专利说明:
The invention relates to a Filte / orrichtung for separating liquid suspended particles from a carrier gas, in particular for separating oil from an oil mist, comprising a housing having at least one inlet opening for introducing the carrier gas and at least one outlet opening for discharging the filtered carrier gas, wherein in the housing at least a filter insert is arranged, which can be traversed by the carrier gas along a flow direction. During operation of an internal combustion engine, so-called blow-by gases are known to be discharged from a crankcase of the internal combustion engine, in order to avoid an increase in the pressure in the crankcase and an undesired escape of blow-by gas and oil contained therein. In closed crankcase ventilation systems, this crankcase ventilation gas or the carrier gas resulting from the blow-by gases in the crankcase is returned to an air intake of the internal combustion engine, wherein the pressure in the crankcase is usually kept within predetermined component limit values. However, the carrier gas contains fine oil droplets and solid particles on the order of about 0.1 pm to 10 pm. In order to avoid negative effects of this oil contained in the carrier gas on components in the air inlet of the internal combustion engine, it is already known to separate the oil and the solid particles from the carrier gas. For this purpose, inter alia filter devices according to the preamble of claim 1 are used, which comprise the carrier gas flow through bare filter cartridges from a knitted wire or knitted fabric. However, such filtering devices achieve only a limited degree of separation due to the underlying deposition mechanisms and the design-related structure of such a wire knit or wire knit for small droplet or particle sizes (in particular in Komgrößenbereicb <1 pm). Downstream of the filter device, therefore, a fine filter (e.g., coalescer filter) may be used which can filter out smaller oil droplets than the separator. The object of the invention is to provide a comparison with the prior art improved filter device. This object is achieved by a filter device with the features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims. According to the invention, it is thus provided that in order to increase a flow velocity of the carrier gas and / or to achieve an extended - preferably labyrinthine - flow path of the carrier gas through the at least one filter insert at least one guide device is provided, through which the flow path can be deflected. By means of a guide device arranged along the direction of flow, the flow cross-section available to the carrier gas is reduced to a correspondingly reduced cross-sectional area through which the carrier gas can flow. This cross-sectional reduction leads to an increased flow velocity of the carrier gas and thus to an increased oil separation in the filter cartridge. Due to the deflection of the carrier gas at the guide devices, in particular with a correspondingly increased flow velocity of the carrier gas-for example more than 0.9 m / s-an increased oil separation can be effected. It can preferably be provided that the at least one guide device is designed as a diaphragm, preferably a plate-shaped diaphragm. The at least one guide device can be attached to the housing, preferably welded, glued or screwed, and at least define an opening which forms a cross-sectional area durchströmbare by the carrier gas through the at least one opening formed by the carrier gas durchströmbare cross-sectional area can in the case of a plate-shaped aperture parallel to the plane of the plate. In particular, in the case of plate-shaped guide devices, the filter inserts can be easily inserted into the housing and do not necessarily need to be connected or sealed to the housing itself. In a preferred embodiment, it can be provided that the at least one filter insert is formed from a woven, braided, knitted, knitted or nonwoven fabric, which consists of at least one filter wire or at least one filter fiber with a diameter smaller than 0.2 mm, preferably smaller than 0.1 mm, is constructed. For small drop sizes, the separation efficiency of the filter insert depends on the diameter of the filter wires or the filter fibers. Small wire or fiber diameter increase the separation efficiency of the filter insert. Preferably, it can be provided that a volume fraction of the at least one filter wire or the at least one filter fiber in the filter insert is about 2% to 5%, preferably substantially 4%. Depending on the choice of the volume fraction of the filter wires or filter fibers, it is possible to influence the degree of separation of the filter insert. However, an increased volume fraction will cause an increased pressure drop across the filter cartridge. Therefore, it is useful to take into account in the dimensioning of the volume fraction of the filter wires or filter fibers as well as in the dimensioning of the lengthened flow path caused by the at least one guide device possibly predetermined limits for a maximum pressure drop through the filter device. Due to the proposed dimensioning of the filter insert, a particularly effective separation of oil from a carrier gas can be achieved. Experiments by the Applicant have shown that with the proposed dimensioning a high reduction of the oil mass contained in the carrier gas can be brought about, whereby the oil load for downstream fine filter, such as coalescer filter, can be significantly reduced. This increases the life of the downstream fine filter, which are to be replaced regularly due to their oil pollution. According to a particularly preferred embodiment it can be provided that the at least one filter wire or the at least one filter fiber at least partially, preferably substantially completely, consists of metal, preferably of stainless steel or aluminum. In other words, it can thus be provided that the filter insert is formed from a metal mesh. A particularly good filtering effect can be achieved if an increased flow velocity of the carrier gas of at least 0.6 m / s, preferably at least 0.9 m, by suitable dimensioning of the at least one guide device and thus the resulting cross-sectional areas permeable by the carrier gas in the at least one filter insert / s, is reached. The cross-sectional area through which the carrier gas can flow or through can be a cross-sectional area extending transversely to a flow path of the carrier gas through the filter insert, through which the carrier gas can flow through the filter insert. However, the increased flow velocity of the carrier gas in the filter insert caused by the arrangement and dimensioning of the guide devices should be below the so-called flood point of the filter insert, ie below the speed at which drops are discharged from the filter insert. According to a preferred embodiment it can be provided that along the flow direction a plurality of filter cartridges is arranged one behind the other. To achieve a prolonged, preferably labyrinthine, flow path of the carrier gas through the plurality of filter cartridges at least between two of the filter cartridges arranged one behind the other, preferably between all of the filter cartridges arranged one behind the other, at least one guide device can be arranged. Particularly preferred is that embodiment in which are limited by the guide devices openings viewed in the flow direction offset from one another, wherein preferably formed by the openings formed by the carrier gas flow cross-sectional areas are substantially equal. Due to the staggered arrangement of the openings of the respective guide devices, a labyrinth-like structure results in relation to the flow path of the carrier gas through the filter device, which extends the path of the flow path accordingly. If the flow-through cross-sectional areas are substantially equal, a constant flow velocity of the carrier gas through the individual filter cartridges can be achieved. Depending on the application, however, it may also be useful to change the cross-sectional areas through which the carrier gas can flow and thus the flow velocity of the carrier gas along the flow path. For example, it may be provided to increase the flow velocity by dimensioning the openings during the transition from the first to the second filter insert (viewed in the flow direction) and to reduce it again when emerging from the second filter insert. A structurally particularly simple to manufacture variant can provide that the housing is substantially cuboid-shaped, wherein the housing has a length, a width and a height. Preferably, it may be provided that length to width have a ratio of about 1: 1 to 1: 2 and / or have a length to height ratio of about 2: 1 to 3: 1. Depending on the application, the housing is more or less populated with filter cartridges. Thus, it can be provided that the length of the housing to a total filter insert height of all located in the housing filter inserts has a ratio of about 2: 1 to 10: 1. MH other words, it may well be provided that only a portion of the housing height is actually equipped with filter cartridges - preferably starting from the at least one inlet opening of the housing - and the rest of the housing remains empty. Genereil can be provided that an inlet surface of the at least one inlet opening of the housing formed transversely to the flow direction and / or by Leitvorrichtungen by the carrier gas through cross-sectional areas transversely to the flow direction at least 10% and / or at most 40%, preferably at most 30%, a clear housing cross-section transverse to Flow direction is or amount. As a result, an increased flow velocity of the carrier gas and thus increased oil separation in the filter element can be achieved. Protection is also desired for an oil by-pass separator according to claim 15, which in particular can serve for the separation of oil in a crankcase ventilation gas of an internal combustion engine. Preferably, it may be provided that the at least one filter device is arranged inclined to the vertical, wherein the flow direction through the filter device with the vertical angle of about 30e to 90 °, preferably substantially 45 °, includes. It is particularly favorable if an inlet opening of the filter device in mounting position extends at least in sections inclined to the vertical, preferably up to a lower end of the filter device with respect to the vertical. The inlet opening may preferably extend along a housing wall of the housing of the filter device, wherein a lower edge of the housing wall with the vertical an angle of about 30e to 90 °, preferably substantially 45 °, includes. Preferably, it can be provided that the guide devices are arranged inclined in the filter device corresponding to the vertical, for example, by running parallel to the plane of the inlet opening. By inclined to the vertical arrangement of the filter device of the oil mist separator, the targeted flow of the separated oil along the guide devices or panels back to the inlet opening of the filter device can be achieved on the Rohgasseite. The outflow can occur due to gravity along the guide devices, whereby the drainage behavior can be improved because the oil return and the gas flow of the carrier gas are separated from each other. According to an advantageous embodiment, the at least one filter device can be arranged detachably in the oil mist separator, wherein a preferably peripheral seal is provided between a first attachment surface of the oil mist separator and a second attachment surface of the filter device to be fastened thereto. As a result, a bypass of the filter device can be avoided by passing past portions of the carrier gas. Preferably, it can be provided that the oil mist separator in relation to a flow path of the carrier gas in front of the at least one filter device has a first housing chamber, which has an increased free flow area transversely to the flow path of the carrier gas relative to an entrance surface of the at least one inlet opening of the housing of the filter device. It can also be provided that the oil mist separator has a second housing chamber with respect to a flow path of the carrier gas downstream of the at least one filter device, which has an increased free flow area transverse to the flow path of the carrier gas relative to an exit surface of the at least one outlet opening of the housing of the filter device. In addition, protection is desired for an internal combustion engine according to claim 21, wherein preferably on the crankcase, a proposed oil separator is arranged. Further details and advantages of the present invention will be explained with reference to the following description of the figures. It shows or show: 1 is a schematic sectional view through a filter device according to the prior art, 2 is a schematic sectional view through an embodiment of a proposed filter device, 3 is a bottom view of the filter device of FIG. 2, Fig. 4 is a schematic sectional view through another Embodiment of a proposed filter device, 5 shows a perspective top view of a further exemplary embodiment of a proposed filter device, and FIG. 6 shows a schematic illustration of an internal combustion engine with a proposed oil mist separator comprising a proposed filter device. Fig. 1 shows a schematic Schnittdarsteliung a filter device 1 according to the prior art, comprising a housing 3 and a housing 3 arranged in the filter cartridge 6. The housing 3 of the filter device 1 has an inlet opening 4 for introducing a carrier gas 2 in the filter device 1 and an outlet opening 5 for draining the filter gas 6 filtered by the filter gas 2 from the filter device 1. The flow through the carrier gas 2 - to be separated from the liquid suspended particles such as oil - through the filter cartridge 6 along a flow path 16 is indicated by a dashed line. Starting from the inlet opening 4 up to the outlet opening 5, the carrier gas 2 flows through the filter device 1 along a flow direction 7. In this example, the housing 3 has a substantially rectangular cross-section transverse to the flow direction 7 so that a rectangular, light is formed transversely to the flow direction 7 Housing cross-section 10 results. The inlet opening 4 of the housing 3 has transversely to the flow direction 7, a likewise rectangular inlet surface 20, which corresponds to a carrier gas from the 2 ruchström ble cross-sectional area 11. 2 shows a schematic sectional illustration through an exemplary embodiment of a proposed filter device 1 for separating oil from an oil mist or carrier gas 2. The filter device 1 comprises a housing 3, in which a filter insert 6 is arranged. The filter insert 6 is formed in this example of a wire mesh of stainless steel wires, the filter wires 8 of the wire mesh having a wire diameter less than 0.2 mm, preferably less than 0.1 mm. The housing 3 has in this example two inlet openings 4, which form transversely to the flow direction 7 in total an inlet surface 20 through which the carrier gas 2 can enter the housing 3 and flow along the flow paths 16 through the filter cartridge 6. Two guide devices 9, which are arranged in the flow direction after the filter element 6 on the housing 3, define an opening 12, which corresponds in this example to the outlet opening 5 of the housing 3, through which the carrier gas 2 can escape from the filter device 1. By selecting suitable sizes of the inlet openings 4 and thus by selecting a suitable inlet surface 20, the flow velocity of the carrier gas 2 can be influenced, preferably the inlet openings 4 and the inlet surface 20 is selected so that the flow rate of the carrier gas 2 through the filter insert 6 at least 0th , 6 m / s, preferably at least 0.9 m / s. The thickness of the filter insert 6 or the distance 25 between inlet openings 4 and guide devices 9 viewed in the flow direction 7 is selected in this example so that the resulting cross-sectional area transversely to the flow path 16 through the filter element 6 is substantially half as large is formed by the two inlet openings 4 entrance surface 20. The formed by the opening 12 and outlet opening 5, durchströmbare by the carrier gas 2 cross-sectional area 11 is selected in this example substantially the same size as the entrance surface 20 (formed by the two inlet openings 4) so that a substantially constant flow velocity of the carrier gas 2 is established along the flow paths 16 through the filter insert 6. 3 shows a bottom view of the filter device 1 of FIG. 2. As can be seen in this illustration, the base of the housing 3 of this embodiment of the filter device 1 has a rectangular shape with a length 17 and a width 18. The inlet openings 4, through which the carrier gas 2 can flow into the filter device 1, run in this example along two housing walls 13 of the housing 3 and extend over the entire width 18 of the housing 3. The two inlet openings 4 in total form an entrance surface 20, through which the carrier gas 2 can flow into the filter device 1. 4 shows a further exemplary embodiment of a proposed filter device in a schematic sectional illustration. Compared to the embodiment of FIG. 2, a plurality of filter cartridges 6 are arranged one behind the other in the flow direction 7. Between the filter cartridges 6 guide devices 9 are arranged on the housing 3, through which the flow paths 16 of the flowing through the filter cartridges 6 carrier gas 2 are respectively deflected accordingly. The Guiding devices 9 - which are arranged substantially perpendicular to the flow direction 7 - thereby each form openings 12, which are viewed in the flow direction 7 offset from each other. This results in a total of a labyrinthine structure, whereby the flow paths 16 extend accordingly. In this example, all of the resulting cross-sectional areas 11 which can be flowed through by the carrier gas 2, as well as the entrance surface 20 of the inlet openings 4, are dimensioned substantially equal, resulting in a substantially constant flow velocity of the carrier gas 2 along a flow path 16. Depending on the application, however, it may also be useful to change the cross-sectional areas 11 which can be flowed through by the carrier gas 2 and thus the flow velocity of the carrier gas 2 along the flow path 16. For example, it may be provided to increase the flow velocity by dimensioning the openings 12 during the transition to the second filter insert 6 (viewed in the flow direction 7) and to reduce it again when emerging from the second filter insert 6. The guide devices 9 between two filter cartridges 6 are arranged in the example shown in the flow direction 7 at a distance 25 on the housing 3. By a suitable choice of entrance surface 20, the carrier gas 2 through-flow cross-sectional areas 11 and distances 25 between the guide devices 9 influence on the flow rate of the carrier gas 2 at a given volume flow of the carrier gas 2 can be taken. Depending on the application, such as Thus, the internal combustion engine to be equipped with a filter device 1 can be adapted to the constructionally particularly easy-to-influence values for entry surface 20, cross-sectional areas 11 and distances 25 through which carrier gas 2 can flow in order to achieve an optimum filtering effect. In particular, by adapting these values, filter devices 1 can be provided for a wide range of different internal combustion engines, which can all have the same outer housing dimensions. FIG. 5 shows a further example of a proposed filter device 1 similar to FIG. 4 in a perspective top view. For the sake of clarity, in this case the filter inserts 6 and a front side wall of the housing 3 have been hidden. As can be seen from the figure, the inlet openings 4 and the openings 12 delimited by the guide devices 9 run essentially along the entire width 18 of the housing 3. The labyrinth-like internal structure of the filter device 1 can also clearly be seen, which is achieved by the guide devices 9 becomes, 6 shows a schematic representation of an internal combustion engine 15, on whose crankcase 21 a proposed oil mist separator 14 with a proposed filter device 1 is arranged. The internal combustion engine 15 may be, for example, a gas engine in which a charge air is introduced in a known manner via an air inlet 24. In the crankcase 21 of the internal combustion engine 15 resulting blow-by gas or carrier gas 2 is passed into the oil mist separator 14. After the oil mist separator 14, which is used as a pre-filter, the carrier gas 2 passes into a fine filter 22 to remove smaller oil droplets, which can not be separated from the oil mist separator 14, from the carrier gas 2. After the fine filter 22, the carrier gas 2 - via a separate chamber 28 of the Ölnebelabscheiders 14 - returned to the air inlet 24 and thus the charge air. Along this flow path, the flow of the carrier gas 2 takes place due to the prevailing pressure conditions in the air inlet 24. In the oil mist separator 14, a filter device 1 is arranged, which is flowed through by the carrier gas 2 along a flow direction 7. In this case, an oil contained in the carrier gas 2 is at least partially separated. By a correspondingly inclined arrangement of the filter device 1, so that the flow direction 7 is inclined by the filter device 1 to the vertical with an angle 23, the oil deposited in the filter device 1 can be targeted, for example, at one of the inlet openings 4 of the filter device 1, drained. The angle 23 is in the example shown about 45e to the vertical. The oil mist separator 14 shown here has settling zones for the carrier gas 2 in the form of a first housing chamber 26 and a second housing chamber 27 before and after the filter device 1. Both the first housing chamber 26 and the second housing chamber 27 each have a free flow area increased transversely to the flow path of the carrier gas 2 in comparison to the entry area 20 of the at least one inlet opening 4 of the filter device 1 or exit area of the at least one outlet opening 5 of the filter device 1. Due to the thus reduced flow velocity of the carrier gas 2 on the one hand in the first housing chamber 26 large drops of oil can be eliminated before the filter device 1 from the carrier gas 2 and on the other hand oil drops in the second housing chamber 27 after the filter device 1 not by an excessive flow velocity of the carrier gas. 2 carried away. The prefiltered in the oil mist separator 14 carrier gas 2 is subsequently fed to the fine filter 22, after which it is recycled via a third housing chamber 28 of the oil mist separator 14 to the air inlet 24 of the internal combustion engine 15.
