    [0001] [001] The present invention relates to a filtering device for separating paint overspray from a stream of crude gas, containing overspray particles, the filtering device comprising at least one filter, to which it can be conducted at least a portion of the raw gas stream and a pure gas chamber to which the raw gas stream, filtered through the filter element, can be conducted as a pure gas stream.
    [0002] [002] Such a device has come to be known, for example, from DE 10 2007 040 901 A1.
    [0003] [003] If a filter is mechanically damaged in a filtering device of this nature, so that at one or several points, the stream of raw, unfiltered gas reaches the pure gas side of the filtering device, the side of pure gas of the filtering device and the areas of a painting installation located downstream of the filtering device, which installation contains the filtering device, will be made impure by the dirt particles, not eliminated in the filtration of the crude gas stream (especially overspray particles and eventually particles of a supporting filter material).
    [0004] [004] The objective of the present invention is to keep the formation of impurities on the pure gas side of the filtering device and of a paint installation containing the filtering device in the least possible extent, in the event of a rupture in at least one element filtering device.
    [0005] [005] In a filtering device with the characteristics of the preamble of claim 1, this task, according to the invention, will be solved by the fact that for the pure gas chamber of the filtering device, at least one filter is allocated. security, located downstream of at least one filter, through which at least a portion of the crude gas stream - in the event of a filter break - can be filtered through at least one filter of the filtering device.
    [0006] [006] The present invention is based on the concept that in the event of a rupture of the filter, through the main filter that is formed by at least one filter of the filtering device, the material passed through will be captured close to the site, so that sequential components of the installation, especially fans, sensors and air conditioning devices (for example, refrigerators and / or humidifiers) of the pure gas chamber, in the course of the flow of the pure gas stream, are protected against impurities in the case of rupture of the filter.
    [0007] [007] In order to keep the path that is covered by the unfiltered raw gas as short as possible, in the event of a rupture of the filter, on the pure gas side of the filtering device to the safety device, it will be advantageous that the safety filter is integrated into the pure gas chamber of the filtering device.
    [0008] [008] In particular, it can be provided that at least one safety filter is disposed inside the pure gas chamber or in a limiting wall of the pure gas chamber.
    [0009] [009] The pure gas chamber can be shaped, for example, as a pure gas box, essentially in the shape of a cobblestone.
    [0010] [0010] At least one filter element of the main filter preferably includes a filtering diaphragm that serves to separate the paint overspray from the raw gas stream. Damage to the filter diaphragm, made possible by an unfiltered passage of the raw gas stream containing overspray particles, passing through the filter, represents a break in the corresponding filter.
    [0011] [0011] Preferably, the filtering device comprises a main filter which in turn comprises at least one filter conformed as a dry filter, that is, a filter with which a dry filtration can be carried out. A dry filtration is a filtering of the gas stream that passes through the filter, which occurs without washing with a washing liquid. This does not exclude that a layer formed in the course of filtration next to the filter, covering material to be removed in the filtration, and eventually supporting filter material, is rinsed by being subjected to a liquid cleaning product.
    [0012] [0012] Preferably, the main filter covers only dry filters.
    [0013] [0013] When the filtering device comprises a main filter with several filter elements, then it is preferentially provided that the pure gas chamber receives the pure gas streams from several, preferably all, filters of the filtering device.
    [0014] [0014] In addition, it is preferably provided that at least one filter element is kept in the pure gas chamber of the filtering device.
    [0015] [0015] For this purpose, the pure gas chamber can comprise a filter fitting with at least one filter retainer and preferably a fitting opening for the passage of the filters in a filter fitting compartment of the filtering device.
    [0016] [0016] When the filtering device, according to the invention, is part of a device for separating paint overspray from a stream of crude gas containing overspray particles, covering several of these filters, then it will be advantageous that the filtering device The filtration covers a pure gas channel, through which pure gas can be conducted from the pure gas chamber of the filtering device to a pure gas collecting channel, the pure gas collecting channel also receiving pure gas from at least one other device. filtering and moving to sequential sections of the installation, for example, containing a fan and / or an air conditioning device (especially a cooler and / or a humectant).
    [0017] [0017] In order to keep the formation of impurities in the pure gas collecting channel and the components of the paint installation sequential to the pure gas collecting channel in the least possible extent, it will be advantageous that the security filter of the filtering device is arranged upstream of a plunger in the pure gas channel, in the pure gas collector channel.
    [0018] [0018] Preferably, all filtering devices of the device for separating overspray of paint, from a stream of crude gas containing overspray particles, have a security filter of this nature, which is arranged upstream of the hull of the respective pure gas channel of the filtering device in question, within the pure gas collecting channel.
    [0019] [0019] It is thus ensured that each safety filter allocated to a filtering device of this type, in the event of a rupture of the filter in the corresponding filtering device, will have to filter only the portion of the crude gas stream that passes through the filtering device respective.
    [0020] [0020] In this way, the security filter of each filtering device can be kept relatively small.
    [0021] [0021] Preferably, each of the other filtering devices of the device for separating ink overspray from the raw gas stream, containing overspray particles, has its own intake channel through which a portion of the gas stream can always be conducted for the respective filtering device.
    [0022] [0022] Preferably, the portions of the crude gas stream that are conducted to the different filtering devices, between themselves, are essentially of identical size, so that also the safety filters, allocated to these filtering devices, based on the current essentially uniform in volume, through differentiated filtering devices, they can essentially be kept to the same extent and, therefore, the size of the safety filters can be standardized.
    [0023] [0023] In this way, preferably, for all filtering devices of the device for separating paint overspray from the raw gas stream, containing overspray particles, the same type of safety filter can be used, with the same elements of security filtering.
    [0024] [0024] According to a preferred embodiment of the invention, it is provided that at least one safety filter is arranged in such a way in the filtering device that at least one filtering element can be removed from the filtering device, without first removing the safety filter. It is thus ensured that the integration of the safety filter in the filtering device, the assembly and disassembly, as well as the maintenance and repair of the filtering elements of the filtering device is not hindered.
    [0025] [0025] Preferably, all the safety filters of the filtering device are so arranged in the filtering device that all filter elements can be removed from the filtering device, without first removing one of the safety filters.
    [0026] [0026] Basically, as a security filter, any type of filter that is suitable for filtering out the particles entrained in the crude gas stream and that resist the volume stream, which in case of a rupture of the filter, will be used as a filter through the safety filter.
    [0027] [0027] Preferably, the safety filter comprises at least one dry filter, that is, a filter with which dry filtration can be carried out. A dry filtration is a filtering of the gas stream that passes through the filter and which is verified without rinsing with a cleaning liquid. This does not exclude that a layer of material to be removed by filtration, conformed to the filter during filtration, and eventually supporting filtering material are removed by rinsing by being subjected to a liquid cleaning product.
    [0028] [0028] Preferably, the safety filter contains only dry filters.
    [0029] [0029] A dry filtration offers the advantage that the temperature and humidity of the gas stream that passes through the filter, in this case, is at least approximately constant, so that the gas stream that passes through the filter, after passing through the filter filter, it does not need to be conditioned in relation to its temperature and / or
    [0030] [0030] The safety filter can be, for example, a shock filter, a bag filter, a tubular filter, a belt filter, a plate filter and / a tube filter.
    [0031] [0031] The safety filter may be permanently disposed in the flow path of the pure gas stream and may be activated for the filtering of the gas stream that passes through the safety filter.
    [0032] [0032] In an alternative or complementary way, it can be provided that at least one safety filter, in the event of a filter break in a filter element, is activated for the filtration of crude gas that passes through the filter. This offers the advantage that the safety filter in question does not re-filter the pure gas that has been filtered before by the main filter filters, but only in the event of a filter break in at least one of the filters of the filtering device will it then be activated the necessary filtration for the crude gas that passes through the main filter. In this way, unnecessary increase in flow resistance on the pure gas side of the filtering device, in the normal operating state of the filtering device, will be avoided.
    [0033] [0033] An activation of this nature of a safety filter in the event of a filter break can, for example, be verified by the fact that at least one safety filter covers at least one safety filter element that in a normal state of operation of the filtering device is arranged in a waiting position, outside the flow path of the pure gas and, through a suitable displacement device, in the event of a rupture of the filter, it can be moved to a working position along the path of the flow of crude gas through the main filter of the filtering device.
    [0034] [0034] Preferably, the movement device has a motorized drive for the movement of at least one filter element.
    [0035] [0035] By means of a mechanical movement device, in the event of a filter rupture, elements of safety filters that can be introduced in the flow path, can be formed, for example, as a filter plate, a bag filter or a shock filter.
    [0036] [0036] In an alternative or complementary way, a safety filter may also be activated by the fact that it comprises at least one safety filter element, which, in the normal operational state of the filtering device, allows the passage of the pure filtered gas essentially and only in the event of a filter break (preferably automatically) it will be filled with a suitable filter material.
    [0037] [0037] For example, a security filter element of this type can cover a reception for the filtered material, especially in the form of a mesh or a grid which in the event of a rupture of the filter will be filled with filtered material, from the filter material reservoir, for example, with a particulate charge of filtered material.
    [0038] [0038] A filter material suitable for filling a safety filter element of this type, in the event of a filter break is, for example, gravel, sand, iron chips or similar materials.
    [0039] [0039] In an alternative or complementary way, a safety filter can also be activated in this way, in the event of a filter break, being that it covers at least one safety filter which in the case of a filter break, can be activated by application of an electrical voltage.
    [0040] [0040] A safety filter of this type can be specially designed as an electrostatic filter.
    [0041] [0041] In order that when using a safety filter that can be activated only in case of damage, the safety filter can be activated in a timely manner, or in the case of a permanently activated safety filter, it can alarm the operators of the painting installation, or in order to be able to determine for how long the safety filter will be subjected to the raw gas reaching the pure gas side of the filtering device, when it will be advantageous for the filtering device to include at least one device for detecting a rupture of a filter.
    [0042] [0042] Such a detector device may, for example, comprise a particle counter, a pressure loss meter, a filter resistance meter to measure the flow resistance of at least one filter element of the main filter, and / or a filter position meter to measure the through resistance of at least one safety filter.
    [0043] [0043] In a preferred embodiment of the invention, it is also provided that in order to filter the stream of crude gas a supporting filtering material and at least one filtering element of the filtering device is used, in the operation of the filtering device, it has a layer blocking material containing the supporting filter material.
    [0044] [0044] In this way, it is especially avoided when using a fluid paint that the overspray of the wet fluid paint reaches the filter surface directly. In contrast, the overspray of the liquid paint will be bonded by the filter aid material and / or the filter aid material constitutes a blocking layer between the wet fluid paint overspray and the filter surface.
    [0045] [0045] With the term "fluid paint" in this description - different from the notion of "powder paint" - it is designated a paint with a fluid consistency, from liquefied to pasty (for example, in the case of a PVC paint). The notion "fluid ink" covers especially the notions of "liquid ink" and "wet ink".
    [0046] [0046] As a supporting filter material, lime, rock flour, aluminum silicate, aluminum oxide, silicon oxide, powdered lacquer or similar product are considered especially.
    [0047] - alimentação de ao menos uma parte da corrente de gás bruto para ao menos um filtro, por meio do qual será filtrada a corrente de gás bruto alimentada, e - alimentação da corrente de gás bruto filtrada pelo filtro como corrente de gás puro, até uma câmara de gás puro. [0047] In addition, the present invention relates to a process for separating paint overspray from a stream of crude gas containing overspray particles, which encompass the following steps: - supplying at least part of the crude gas stream to at least one filter, through which the fed crude gas stream will be filtered, and - supply of the raw gas stream filtered through the filter as a pure gas stream, to a pure gas chamber.
    [0048] [0048] The present invention also has the additional task of creating a process of this type for the separation of paint overspray, from a stream of crude gas, containing overspray particles, of which, in the case of a filter break in at least one filter of the filtering device, the formation of impurities on the pure gas side of the filtering device and the regions located downstream of the filtering device of a painting installation containing the filtering device will be maintained to the smallest extent possible. filtration.
    [0049] [0049] This task will be solved in a process for the separation of a stream of crude gas, containing paint overspray, integrated in overspray particles, according to the characteristics of the preamble of claim 15, according to the information, it will be solved by the fact that in the event of a filter break, in at least one filter, the raw gas stream fed to the pure gas chamber will be filtered through a safety filter, disposed downstream of the filter and allocated to the pure gas chamber.
    [0050] [0050] The filtering device according to the invention is specially adapted for carrying out a process according to the invention, for the separation of paint overspray, from a stream of crude gas, containing overspray particles.
    [0051] [0051] The length of the segment of the gas flow path, made impure in the event of a filter rupture, between the pure gas chamber and the safety filter, will be minimized.
    [0052] [0052] Preferably, machine components that could become dirty in the event of a filter break are not integrated between the main filter element and the safety filter.
    [0053] [0053] The safety filter that is allocated to the pure gas chamber of a single filtering device, may be smaller in size than the safety filter that would be integrated in a pure gas collecting channel or an air collecting channel environment.
    [0054] [0054] The safety filter allows for a safe dry separation of particles from the crude gas, in the event of a filtration rupture, with the need for additional space only reduced.
    [0055] [0055] In the case of a relocation of an existing painting installation, safety filters can be easily added to the pure gas chamber, allocated to a single filtering device; in this way, there will be no need for additional space for a safety filter in a pure gas collecting channel or in an ambient air collecting channel.
    [0056] [0056] The safety filter can be positioned in any imaginable position, after receiving the filter fitting. In particular, it may also be integrated in the pure gas chamber, above the pure gas chamber, below the pure gas chamber, or in a horizontal position, after the pure gas chamber.
    [0057] [0057] The safety filter may be arranged in such a way that it does not affect the disassembly of the filter elements of the main filter or the filtering device.
    [0058] [0058] A corresponding conformation fitting of the safety filter allows simple assembly and disassembly of the safety filter and easy access to the safety filters for maintenance purposes.
    [0059] [0059] This can be made possible, for example, by the fact that the safety filter can be extracted from a frame in a perpendicular direction towards the inflow direction.
    [0060] [0060] In an alternative or complementary form, it may also be provided that the safety filter can be extracted, together with the frame, from the flow path of the gas stream, especially from a channel structure.
    [0061] [0061] The safety filter may include, for example, an F5 bag filter.
    [0062] [0062] The safety filter can be equipped with a control that registers when the safety filter has, for example, a greater resistance passage. In this way, a filter rupture can be registered indirectly, because the resistance to the passage of the safety filter will increase, when particles precipitate in the safety filter, from the raw gas that in the case of a filter rupture reaches the filtering device. on the pure gas side.
    [0063] [0063] A filter occupancy detection in the safety filter can also be combined with a measurement of particle emissions; in this way, a break in the main filter of the filtering device may be prematurely recognized.
    [0064] [0064] A measurement of particle emissions can also be used independently, that is, without an additional measurement of filter resistance for the purpose of detecting a filter break.
    [0065] [0065] The safety filter can be permanently active or can be activated in the event of a break in the main filter of the filtering device.
    [0066] [0066] The detection of damage to the main filter can be done, for example, through a particle counter, by modifying the pressure loss in the main filter and / or by changing the resistance of the filter elements of the main filter, when cleaning with pressurized air.
    [0067] [0067] In the detection of a filter break, the safety filter stage can be applied. This will minimize the pressure loss required during normal operation of the filtering device and at the same time ensure the necessary safety against the formation of impurities in the event of a filter break.
    [0068] [0068] The safety filter of the filtering device of the invention is arranged close to the filter elements of the main filter.
    [0069] [0069] Preferably, between the main filter and the safety filter, allocated to the main filter, no additional pure gas streams occur, so the safety filter will only have to be set for the partial gas stream that crosses the respective allocated filtering device.
    [0070] [0070] The path of the gas channel between the rupture point and the safety filter, which becomes impure in the event of a rupture of the filter by particles from the raw gas stream, will thus be kept to a small extent, so that the filter safety device is arranged next to at least one element of the main filter of the filtering device.
    [0071] [0071] Preferably, between at least one filter element of the main filter and the allocated safety filter, there are no fans, sensors, or conditioning devices (such as, for example, air conditioning units and / or humectants) in the path of flow of the gas stream.
    [0072] [0072] Other features and advantages of the invention are the subject of the following description and drawings of examples of execution.

    [0081] [0081] Equal elements or equivalent function are designated in all figures with the same reference numbers.
    [0082] [0082] A device, shown in figures 1 to 3, in all designated with the number 100, designed to separate overspray of fluid paint from a stream of crude gas, comprises one or more filter modules 102, in the present description also designated as filtering devices, of which one unit is shown in figures 1 through 3.
    [0083] [0083] The device 100 for separating overspray of fluid paint forms part of a painting installation for the jet painting of parts, for example, bodies of motor vehicles that are transported through an application area of the painting installation and in the area of application through jet painting sets (not shown), for example, in the form of painting robots, are painted.
    [0084] [0084] Through an ambient air cycle, an air current is generated that crosses the application area and collects an overspray of paint in the form of overspray particles. The term "particles" in this case covers both solid and liquid particles, especially droplets.
    [0085] [0085] In the use of fluid ink, the overspray of fluid ink is composed of ink droplets. Most of these overspray particles have a maximum size, in the range of approximately 1 μm, to approximately 100 μm.
    [0086] [0086] The exhaust air stream, charged with the overspray particles from the application area, will then be designated as crude gas stream 104. The flow direction of the crude gas stream is shown in figures 2 and 3 with arrows designated with the number 104.
    [0087] [0087] The crude gas stream 104 passes from the application area to the device 100 for separating fluid paint overspray from the crude gas stream, which, preferably, is provided below the application area.
    [0088] [0088] The filter modules 102 of the device 100 can be arranged especially in two rows of modules on the two opposite sides of a flow chamber, of which a vertical side wall 105 is shown in figure 2.
    [0089] [0089] Between the two rows of modules there may be a footbridge 106 (see figure 2), in which an operator can be moved.
    [0090] [0090] Each of the filter modules 102 is preferably formed as a pre-assembled unit that is produced in a location far from the assembly site of the painting installation and of the device 100 for the separation of the fluid paint overspray and that is transported as a unit to the location of the installation of the painting installation. At the assembly site, the pre-assembled unit will be arranged in the intended working position and will be joined with one or more neighboring pre-assembled units, as well as with a supporting construction of the application area.
    [0091] [0091] Each filter module comprises a support construction 108 of two rear vertical supports 110 and two front vertical supports 112 which through transverse beams 114 are joined with one of the rear supports 110.
    [0092] [0092] In addition, the front supports 112 and the rear supports 110, at their upper ends, are interconnected through a horizontal beam (not shown).
    [0093] [0093] The filter module 132 also comprises a housing 116 that separates a plug-in compartment from the filter element 118 from the filter module 102, disposed within the housing 116, from an area 120 of the flow chamber located externally from the housing 116.
    [0094] [0094] In the compartment of the insert of the filter element 118 of the filter module 132 there are arranged several filter elements 122 which are retained by a pure gas chamber 124, maintained in the support construction 108, standing out in a horizontal direction.
    [0095] [0095] The filter elements 122 can be formed, for example, as sintered polyethylene plates which on their external face have a polytetrafluoroethylene (PTFE) diaphragm.
    [0096] [0096] The PTFE diaphragm serves to increase the filtering class of the filter elements 122 (that is, to reduce their permeability) and, in addition, to prevent the permanent adherence of the fluid paint overspray, separated from the gas stream crude 104, adherence is on the surface of the filter elements 122.
    [0097] [0097] The diaphragm of the filter elements 122 furthermore preferably contains a component with an electrically conductive capacity, for example, graphite, to guarantee a derivation of electrostatic charges from the filter elements 122 and anti-static properties of the filter elements 122.
    [0098] [0098] Both the basic material of the filter elements 122 as well as its PTFE diaphragm have a porosity, so that the crude gas can reach, through the pores, the internal compartment of the respective filter element 122 and from there it can reach the pure gas 124.
    [0099] [0099] To avoid sticking to the filter surfaces, they also have a blocking layer that contains supporting filter material released into the raw gas stream 104. This supporting filter material, preferably in the form of particles, will also be commonly referred to as a so-called "Precoat" material.
    [0100] [00100] The locking layer is formed in the region of the device 100 by separating the supporting filtering material, released in the raw gas stream 104, on the filter surfaces, and prevents these filter surfaces from being stuck by adhering fluid paint overspray .
    [0101] [00101] As an auxiliary auxiliary material, basically any medium that is capable of collecting the liquid portion of the fluid ink overspray and settling on the overspray particles can be used, thus removing its sticky state.
    [0102] [00102] Especially, as supporting filtering materials are considered, for example, lime, rock flour, an aluminum silicate, an aluminum oxide, a silicon oxide, powder paint, or similar material.
    [0103] [00103] Preferably, the filter aid material consists of a variety of particles of aid material that have an average diameter, in the range, for example, from about 10 μm to about 100 μm.
    [0104] [00104] As can be seen from figure 2, the housing 116 comprises a ceiling wall 126, essentially horizontal and a front wall 128 that extends from a front edge 132 of the ceiling wall 126, in a downward direction.
    [0105] [00105] The front wall 128 of the housing 116 comprises an upper segment of the front wall 130 that extends from the front edge 132 of the cover wall 126 to a front edge 134 of the front wall 128, and a lower segment of the front wall 136 that extends. extends from the front edge 134 down to an edge of the front wall 138.
    [0106] [00106] The front wall segment 136 forms an upper supply of an intake channel 140 of the filter module 102 through which a portion of the raw gas stream 104 penetrates into the respective filter module 102.
    [0107] [00107] In order to be able to add the filter aid material in the raw gas stream 104, without the danger that the filter aid material reaches the application area of the painting installation, each filter module 102 has an auxiliary material collecting container 142, attached to the supporting construction108, which, for example, has a tapered shape in the form of an inverse pyramid cone (see also figures 1 and 2).
    [0108] [00108] The upper edges of the side walls 144, for example, four in trapezoidal shape, of the auxiliary material collector container 142 involve an access opening 146 of the auxiliary material collector container 142, through which the gas stream crude 104, loaded with the overspray, can penetrate and exit the auxiliary material collector container 142.
    [0109] [00109] To control in a controlled way the stream of crude gas that enters the filter module 102, inside the compartment 148 of the auxiliary material collection container 142 and to avoid a direct penetration of the stream of crude gas from the flow chamber in the filter elements 122, each filter module 102 has an intake channel 140 which is limited upwards by the lower front wall segment 136 of the housing 116 and, downwards, by a side wall 150 of the displacement footbridge 106.
    [0110] [00110] Due to the small intake cross-section and the consequent high flow rate of the crude gas stream 104 in the intake channel 140, it will be effectively prevented that the supporting filter material passes from inside the filter module 102 -which forms a closed box - inside the flow chamber and from there reach the area of application of the painting installation. A swirling of the supporting filter material in the auxiliary material collecting container 142 and cleaning of the filter elements 122 can therefore be done at any random time, without having to interrupt the supply of raw gas to the filter module 102, or even the operation of jet painting sets in the application area.
    [0111] [00111] Furthermore, due to the fact that the crude gas stream 104, inside the auxiliary material collecting container 142 leaves the intake channel 140 in a controlled manner, it is ensured that a deviation of the crude gas stream 104 occurs in the internal compartment 148 of the auxiliary material collecting container 142. In this way, a sufficient amount of filter aid material that is produced by the swirling of filter aid material, through pulses of pressurized air, will be dragged by the stream of crude gas 104. from a pressurized air lance (not shown) from the forward section that is in the collector of supporting material 142, being moved from the collector of supporting material 142, to the filter elements 102.
    [0112] [00112] The auxiliary auxiliary material dragged by the raw gas stream 104 and the fluid paint overspray, dragged by the raw gas stream 104, will be separated from the filter surface of the filter elements 122 and the raw gas, filtered through the filter elements 122 , passes as clean gas through the porous filter surfaces to reach the internal compartments of the filter elements 122 which are in fluid connection with the internal compartment 152 of the pure gas chamber 152.
    [0113] [00113] As can be better seen in figure 1, where the filter elements 122 of the filter module 102 are not shown, on the front side 154 of the pure gas chamber 124, facing the front side 154 of the collector compartment of the filter element 118 of the filter module 102, a fitting for filter element 156 is formed which comprises a receiving opening 158 and a filter element retention 160, so that the filter elements 122 can be retained in the filter element retention 160, extending from there, through the receiving opening 158, inside the receiving compartment of the filter elements 118.
    [0114] [00114] In the pure gas chamber 124, the pure filtered gas will be collected from all filter elements 122 of the same filter module 102.
    [0115] [00115] As can be seen from figure 2, this collected pure gas passes through one or more channels of pure gas 162 to a collector channel of pure gas 164, disposed outside the flow chamber.
    [0116] [00116] In each of the pure gas collecting channels 164, arranged on both sides of the flow chamber, pure gas channels 162 of the filter modules 102 emerge from one of the two module rows, from several filter modules 122, which are arranged on the opposite sides of the flow chamber.
    [0117] [00117] From the pure gas collecting channels 164, arranged on both sides of the flow chamber, the clean pure gas from the fluid paint overspray, passes to an exhaust air fan (not shown), from where the pure gas , through a cooling register (not shown), and a pipeline (not shown), from an air chamber above the application area (not shown), will be conducted to the full call.
    [0118] [00118] From this air chamber, clean air as pure gas passes through a filtering roof back to the application area, with which the ambient air cycle will be closed by the painting installation.
    [0119] [00119] As the separation of the fluid paint overspray, from the raw gas stream 104, is verified by the filter elements 122 in a dry way, that is, without rinsing with a cleaning liquid, the air conducted in an ambient cycle, in the separation of the fluid paint overspray, it will not be humidified, so that no devices are required for dehydration of the air conducted in an ambient cycle. In addition, no devices are required for separating fluid paint overspray from a rinsing liquid for disposal.
    [0120] [00120] The filter elements 122 will be cleaned by pulses of compressed air, at certain intervals of time, when their load with the overspray of fluid ink and supporting filtering material, has reached a predetermined measure.
    [0121] [00121] The necessary compressed air pulses will be generated through a pulse forming unit 166 which is arranged in the pure gas chamber 124 of each filter element 102. The compressed air pulses generated pass from the internal compartment 152 of the pure gas chamber 124 for the internal compartments of the filter elements 122, and from there they pass through the porous surfaces of the filter to the collector compartment of filter elements 118 of the respective filter module 102, feeling that the blocking layer, formed on the surfaces of the filter, constituted of supporting material filter and the fluid paint overspray precipitated there, will be removed from the filter surfaces, so that these filter surfaces are restored to their original clean state.
    [0122] [00122] The mixture removed by cleaning the supporting filter material and the fluid paint overspray falls down into the supporting material collecting container 142, from where the raw gas stream 104 reaches, and from there it will be recycled back to the elements filtering 122.
    [0123] [00123] When the portion of the ink overspray has reached a higher threshold value in the mixture of the collector material of supporting material 142, the mixture consisting of the filtering material and the ink overspray, will be aspirated from the collector material material 142, being replaced by fresh filter material.
    [0124] [00124] As can be seen better from figures 2 and 3, for the pure gas chamber 124 of each filter module 102, a safety filter 168 is allocated. Safety filter 168 is arranged in the gas flow path pure downstream of the filter elements 122 of the filter module 102. This flow path is shown in figures 2 and 3 by arrows 169.
    [0125] [00125] The safety filter 168 is used so that in the event of a rupture of at least one of the filters 122 (that is, in the case of mechanical damage to the corresponding filter 122, by which crude gas loaded with unfiltered filter aid material and loaded with fluid paint overspray and with supporting filtering material, it can leave the collector compartment of the filter element 118 to the pure side of the filter elements 122, reaching from that point the pure gas chamber 124), you can perform a filtering of the raw gas that reaches the pure side and, in this way, the fluid paint overspray that reached the pure side and the supporting filter material, which reached the pure side, can be separated from the raw gas that reached the clean side, so that the overspray of fluid paint and the supporting filtering material cannot reach the regions of the pure gas channels 162, located downstream of the safety filter 168, as well as the pure gas collector channel 164, can making these regions unclean.
    [0126] [00126] Especially, the safety filter 168 - in the event of a filter break - is prevented from forming impurities in fans and sensors, as well as air conditioning sets (especially air conditioning and / or humectants) in the gas collecting channel pure 164 and in the areas of the ambient air cycle, located downstream of the pure gas collector channel 164.
    [0127] [00127] In the mode shown in figures 1 to 3, the safety filter 168 is permanently integrated in the flow path 169 of the pure gas stream, so that the safety filter 168, in the normal operation of the device 100, for the separation of fluid paint overspray, the pure gas stream will pass through and the pure gas stream will again be filtered through the 168 safety filter.
    [0128] [00128] In this modality, the safety filter 168 may cover, for example, one or more bag filters.
    [0129] [00129] In this case, it may be, for example, F5 pocket filters that have a degree of filtration efficiency of 40% to 60% with particles with a diameter of 0.4 μm.
    [0130] [00130] Each bag filter can have, for example, a passage face in the order of magnitude of about 600 mm x 600 mm.
    [0131] [00131] Alternatively, with a bag filter, a hose filter, a belt filter, a plate filter and / or a tube filter may also be used.
    [0132] [00132] Basically any type of filter is suitable that withstands the volume current that is conducted through the safety filter 168.
    [0133] [00133] Preferably, dry filters will be used, that is, filters with which a dry filtration can be carried out, that is, the filtering of the gas stream that passes through the filter is done without rinsing with a cleaning liquid.
    [0134] [00134] In a dry filtration of this type, the advantage is offered that the temperature and humidity of the gas stream that passes through the filter remains at least approximately constant, so that the gas stream that passes through the filter, after the passage through the filter, does not need to be additionally conditioned, in relation to its temperature and / or its humidity.
    [0135] [00135] The safety filter 168 can also have simple ricochet sheets, through whose deflectors the product to be filtered can be separated (especially overspray of fluid paint and supporting filter material).
    [0136] [00136] Basically, the safety filter 168 can be positioned in any imaginable position downstream of the fitting of the filter element 156.
    [0137] [00137] In particular, the safety filter 168 can be arranged in the internal compartment 152 of the pure gas chamber 124, above the pure gas chamber 124, below the pure gas chamber 124 or in a horizontal position, next to the pure gas 124.
    [0138] [00138] Preferably, the safety filter 168 is arranged in one or several walls of the pure gas chamber 124.
    [0139] [00139] In the embodiment shown in figure 1, the safety filter 168 is arranged on a bottom wall 170 of the pure gas chamber 124.
    [0140] [00140] In this execution example, the bottom wall 170 of the pure gas chamber 124 presents for each safety filter element 172 of safety filter 168, a receiving opening, within which the safety filter element in question 172 it is in such a way hooked on a frame 174 that surrounds the safety filter element 172, so that the frame 174 rests on an internal side of the bottom wall 170 of the pure gas chamber 124, facing towards the internal compartment 152 of the pure gas chamber 124, and the security filter element 172 extends through the slot opening to an area bordering the pure gas chamber 124 of the pure gas channel 162.
    [0141] [00141] In the execution example shown in figure 1, each of the safety filter elements 172 is shaped as a bag filter (176) that comprises a filter element 178 folded in the same way as an accordion, which is attached at its upper edges in table 174 of the respective bag filter 1756.
    [0142] [00142] The security filtering elements 172 can be removed in a vertical direction above the respective allocated opening and can be removed through a maintenance opening 180 of the pure gas chamber 124, in order to be replaced by another safety filter element 172, which will be especially necessary when the respective safety filter element 172, in the event of a filter break in one of the filter elements 122, has been requested for the filtration of crude gas.
    [0143] [00143] One or more maintenance openings 180 may be provided, for example, on a rear side 182 of the pure gas chamber 124, remote from the receiving compartment of the filter element 118.
    [0144] [00144] During the operation of the device 100 for the separation of fluid paint overspray, a maintenance opening 180 of this type is preferably closed by a cover or a door.
    [0145] [00145] Through the maintenance opening 180, the filters 122 that form the main filter of the filter module 102 can also be removed, being removed from the filter module 102.
    [0146] [00146] In this case, the filter elements of safety filters 172 are so shaped and arranged in a limiting wall of the pure gas chamber 124, especially in its bottom wall 170, that the disassembly of the filter elements 122 of the filter module 102, especially the extraction of filters 122 in an essentially horizontal direction through the maintenance openings 108 do not encounter obstacles due to the presence of safety filter elements 172.
    [0147] [00147] In the event of a filter break in one of the filters 122, the damaged filter 122 should be replaced as soon as possible to avoid overloading the safety filter 168 sequentially integrated.
    [0148] [00148] Therefore, it is advantageous that a filter break is detected as soon as possible.
    [0149] [00149] A damage to the main filter of the filter module 102, formed by the filter elements 122, can, for example, be detected through a particle counter 184 which is arranged downstream of the filter elements 122, for example, in the compartment internal 152 of the pure gas chamber 124, being connected with an evaluation unit 188, through a signal line 186. A particle counter of this type reacts in relation to the particles of the overspray and / or the particles of the supporting filtering material that in the in the event of a filter break, they reach the pure side of the filter elements 122.
    [0150] [00150] In an alternative or complementary character, damage to the main filter may be detected by the fact that there is a change in the pressure loss between the raw gas side and the pure gas side of the filter elements 122 of the main filter.
    [0151] [00151] As shown schematically in figure 3, a differential pressure measurement of this nature can be made, for example, through a first pressure sensor 190, disposed in the filter element receiving compartment 118, and downstream of the filter elements. filtering 122, for example, in the internal compartment 152 of the pure gas chamber 124, through a second pressure sensor 192 disposed there.
    [0152] [00152] A differential pressure meter 194, connected with the two pressure sensors 190 and 192, to determine the differential pressure ΔpF through the filter elements 122, can also be connected, via a signal line 196, with the evaluation unit 188.
    [0153] [00153] A reduction of the pressure loss by the filter elements 122 presents a filter passage in at least one of the filters 122.
    [0154] [00154] Pressure sensors 190 and 192 can also be used to detect a change in the resistance of passage of filters 122 in the cleaning by pulses of compressed air by the pulse release unit 166, which also indicates a rupture of the filter in action least one of the filter elements 122.
    [0155] [00155] In addition, in an alternative or complementary way to the aforementioned possibilities, it is also possible to detect a filter rupture in at least one of the filter elements 122, due to the fact that a change in the pressure loss is verified, through the safety filter 168.
    [0156] [00156] To determine the pressure loss ΔpS by the safety filter 168, a pressure sensor 198 may be used, upstream of the safety filter 168, for example, in the internal compartment 152 of the pure gas chamber 124, this sensor is positioned upstream, as well as a pressure sensor 200, downstream of the safety filter 168, for example, in the pure gas channel 162.
    [0157] [00157] The upstream pressure sensor 198 and the downstream pressure sensor 200 can be coupled to a differential pressure meter 202, which, in turn, can be joined via a signal line 204 with the evaluation unit 188.
    [0158] [00158] In the event of a filter rupture in one of the filter elements 122 of the main filter, the differential pressure ΔpS increases through the safety filter 168, since the fluid paint overspray and the supporting filter material reaching the pure side of the filter elements 122, separate on the upstream side of the safety filter 168, which increases the resistance to the passage of the safety filter 168.
    [0159] [00159] Due to the signals transmitted by the particle counter 184, the differential pressure gauge of the main filter 194 and / or the differential pressure gauge of the safety filter 202, the evaluation unit 188 determines whether a filter rupture is present in at least one of the filters 122 and in this case of a filter break produces an alert signal or an alert communication issued to the operators of the painting installation, who can then make a replacement of the defective filter element 122.
    [0160] [00160] A second modality shown in figure 4 of a device 100 for the separation of fluid paint overspray, differs from the first embodiment shown in figures 1 to 3, just in the fact that the safety filter 168, in the second embodiment, different from what happens in the first embodiment, it is permanently activated and the pure gas already filtered by the filter elements 122, will be filtered again in the normal operational state of the filter module 102, but only in case of damage, that is, in the case of a filter break in at least one of the filter elements 122, when it will be activated or applied.
    [0161] [00161] For this purpose, the safety filter 168 in this embodiment comprises at least one safety filter element 172, which, in turn, comprises a fitting of filter material 206 which is arranged in the direction of the flow path 169 of the pure gas, but that in the normal service state of the filter module 102, does not yet contain filter material, so that the safety filter 168, in the normal operating state of the filter module 108, opposes only a very low resistance to the pure gas in ticket.
    [0162] [00162] The material fitting for filtering 206, through a line of material for filtering 208, which can be closed through a flap 210, is joined with a reservoir of filtering material 212, which in normal service state of filter module 102, it is filled with a suitable filter material, for example, gravel, sand, iron chips or the like.
    [0163] [00163] In the normal operating state of the filter module 102, the flap 210 is closed, so that the filter material cannot pass from the filter material reservoir 212 to the filter material fitting 206.
    [0164] [00164] When, however, the evaluation unit 188 detects a filter passage in at least one of the filters 122 of the main filter, the safety filter 168 will be activated, being (from a control device not shown in the device 100 for the separation of fluid paint overspray), the flap 210 will be opened, when the filter material passes to the filter material reservoir 212 - preferably due to the gravity force - for the fitting of the filter material 206.
    [0165] [00165] As a consequence, the fluid paint overspray and the supporting material are separated from the raw gas that reached the pure side of the filter elements 122, in the filtered material of the safety filter 168 that reached the fitting of the filter material 206, from way that the safety filter 168 fulfills its filtering effect.
    [0166] [00166] The fitting of the filtering material 206 can, for example, be formed as a network of coarse meshes which in the case of a filter break is filled with a load of particulate-shaped filtering material, from the material reservoir filter 212.
    [0167] [00167] As in this embodiment, the safety filter 168 will only be activated for the filtration of the gas stream, when a filter rupture is verified in at least one of the filters 122 of the filter module 102, the differential pressure through the safety filter 168 (Δos) in this mode cannot be used to detect the rupture of a filter; on the contrary, the rupture of the filter, in this case, will have to be detected through the particle counter 184 and / or through the differential pressure Aos, through the filter elements 122 of the main filter. Even so, in this modality it may also be useful to control the differential pressure Δps, through the safety filter 168, after the activation of the safety filter 168, in order to verify and be able to evaluate the respective load of the safety filter 168 with overspray. of fluid paint precipitated on the pure side of the filter elements 122 of the pure gas, including filter aid material, to determine how long the safety filter 168 can still be operated in an orderly manner.
    [0168] [00168] In addition, the second modality of a device 100 for the separation of fluid paint overspray, shown in figure 4, with regard to constitution and function, coincides with the first modality shown in figures 1 to 3, whose description precedent, reference is made.
    [0169] [00169] A third embodiment shown in figure 5 of a device 100 for the separation of fluid paint overspray differs from the second embodiment shown in figure 4, in that the safety filter 168 is activated not by filling with the material to be filtered, however by applying an electrical voltage, when a filter break is detected in at least one of the filters 122 of the filter module 102.
    [0170] [00170] The safety filter 168, in this mode, is configured as an electrostatic filter 214 that covers an emitter electrode 216 and one or more separator electrodes 218.
    [0171] [00171] If, between the emitting electrode 216 and the separating electrodes 218, an electrical voltage is applied, the dirt particles will be charged from the raw gas that reached the pure side of the filter elements 122, in the electric field of the safety filter 168 in the opposite direction to the polarity of the separating electrodes 218, being attracted by the separating electrodes 218 and being eliminated there.
    [0172] [00172] The electrical voltage will be applied to the electrodes of the safety filter 168 by the control device of device 100 for the separation of fluid paint overspray, when the evaluation unit 188 has verified a filter rupture in at least one of the elements. filter elements 122.
    [0173] [00173] In the normal operating state of the filter module 102, in which no voltage is applied to the electrodes of the safety filter 168, the safety filter 168 does not essentially offer a resistance to the flow of pure gas.
    [0174] [00174] Furthermore, the third modality, shown in figure 5, of a device 100 for the separation of fluid paint overspray, in relation to the constitution of function, coincides with the second modality shown in figure 4, whose previous description is reference made.
    [0175] [00175] A fourth modality, shown in figures 6 and 7, of a device 100 for the separation of fluid paint overspray differs from the second modality shown in figure 4, in that the safety filter 168 will not be activated by filling of the filter material in a fitting of the filter material 206, existing in the flow path 169 of the gas stream, however due to the fact that one or more filter elements of the safety filter 172, through a handling device 220, schematically shown in the figures 6 and 7, in the event of a filter break, they are introduced into at least one of the filter elements 122 of the filter module 102, only in the flow path 169 of the gas stream.
    [0176] [00176] In the normal operating state, shown in figure 6, of the filter module 102, one or more safety filter elements 172 are arranged outside the flow path of the pure gas stream in a standby position, so that the pure gas stream, in normal operating state, does not experience increased flow resistance.
    [0177] [00177] When the evaluation unit 188 has detected a filter rupture in at least one of the filters 122, by the control device of the device 100 to separate the fluid paint overspray, the movement device 220 will be activated in such a way that at the at least one safety filter element 172 will be moved from the standby position outside the flow path 169 d gas flow, to the working position shown in figure 7, in which the respective safety filter elements 172 are in the flow path. filter 169 of the crude gas which has reached the pure side of the filter elements 122 and, therefore, are effective for separating the fluid paint overspray and the supporting filter material from this crude gas stream.
    [0178] [00178] The elements of mobile safety filters 172 can be formed, for example, as filter plates, filters and bag or shock filters.
    [0179] [00179] In addition, the fourth embodiment, shown in figures 6 and 7, of a device 100 for separating an overspray of fluid paint, in relation to the constitution and function, coincides with the second embodiment shown in figure 4 , to whose previous description, reference will be made.
    [0180] [00180] Due to the fact that in the second to fourth embodiments shown in figures 4 to 7 of a device 100 for separating an overspray of fluid paint, the safety filter stage will only be applied when a passage is detected filter in at least one of the main filters of the filter elements 122, when the pressure loss will be minimized by the safety filter 168 in normal service state of the filter module 102, while at the same time the necessary safety against the formation of impurity on the pure gas side of the ambient cycle of the paint installation in the event of a filter break.
