    The invention relates to a suction device for exhaust gas containing pollutants. It may be particularly preferred in the separating or associated with a 5 material removal thermal processing, as example, a laser processing of components, are used. Especially suitable is an application in the processing of polymeric materials from which components may be formed or coated therewith. In this case, conventionally extracted exhaust gas is passed through a filter element and there is a filtration. Usually, exhaust gas extracted from the environment flows through at least one filter element in which a suitable filter medium is contained. In the filamentous medium, in particular particles but also other components, such as e.g. Oils are held back and the filter medium is loaded or it settles to be separated components on the surface of a filter 16/04/2014 16:12 2/11 No.: R061 P.004 / 014 16/04 2014 MI 16:08 FAX 00423 265 33 01 PPR AG - * - * - * ÖPA 0005/014
    2 or filter element from. Particularly critical are substances or particles which have adhesive properties and therefore adhere to surfaces and here also on the surface of a filter element, which leads to a deterioration of the function of such a filter device during operation, since only a limited application of components to be separated and of a filter aid to be exploited on surfaces. Already after a certain operating tent the surfaces of filter elements are loaded so that no further adhesion and thus no further separation are possible and consequently the filtration effect drops sharply. 10
    For this reason, the surfaces thus loaded are freed of adhesions at more or less large pitches of the tent. It can be exploited that particles or other exhaust components to be filtered out do not adhere very firmly to the surface due to the filter aid used 15 and it is possible to remove these adhesions from the surface, so that the filter effect can be restored. The adhesions can preferably be removed pneumatically.
    Filter aid is usually supplied to the sucked raw gas and it can help the adhesion of the raw gas to be separated constituents on surfaces of a filter element. Since the action of a filter aid decreases during use or also consumes, a metered addition of filter aid can take place. In the removal of buildup, not only are separated components of the exhaust gas removed from a filter element. Part of the filter aid is also removed. This part can be recirculated for cost reasons and used again for further filtration. The return preferably takes place by means of suction from a collecting container. Usually 30 is used in batch mode.
    After a certain period of use, the filter aid loses its effect or its effect is significantly reduced, so that a removal of the no longer usable filter aid and from the exhaust separated 35 components is required. For this purpose, a removal of the collecting container with contained therein no longer usable filter aid and already 16/04/2014 16:12 3/11 No .: R061 P.005 / 014 16/04 2014 KI 16:08 FAX 00423 265 33 01 PPR AG - ÖPA 0006/014 ·· ·· ·· ···· ····················································································· ···························································································································· However, this is complex and represents a source of danger, as there may be contaminations that can lead to health impairment. In addition, this removal causes problems due to the sticky and sticky components contained in the sump.
    It is therefore an object of the invention to facilitate the handling and safety of devices for the extraction and purification of exhaust gases and increase. 10
    According to the invention, this object is achieved with a suction device having the features of claim 1. Advantageous embodiments and further developments of the invention can be realized with features described in the subordinate claims. 15
    The suction device according to the invention is designed so that contaminants containing raw gas is sucked by means of a compressor from the environment and fed to a filter chamber. The raw gas is preferably added filter aid before the filter chamber. In the process, they are deposited on the surface of the filter chamber, ie on its inner walls or on the
    Surface of a filter arranged in the filter Fllterhllfsmlttel and components to be separated from the raw gas and adhere to it.
    In more or less large time intervals, the thus loaded inner wall 25 of the filter chamber or a filter is freed of these adhesions and there is an emptying into an intermediate collection chamber. In this case, adhering components can be removed / separated from the filter aid, so that they are then loosely contained in the intermediate collection chamber in addition to filter aid. 30
    By opening a return line can filter aid from the Zwi-collection chamber, which is advantageously arranged vertically below the filter chamber, are returned to the filter chamber, so that a multiple use of Fllterhllfsmittels is achievable. The promotion of the filter-35 tool from the intermediate collection chamber in the filter chamber can be done by some means of negative pressure. In this case, the compressor of the 16/04/2014 16:13 4/11 No .: R061 P.006 / 014 16/04 2014 MI 16:09 FAX 00423 265 33 01 FFR AG - · - »- > ÖPA 0007/014 ······················································································ ·····························
    AbsaugelnrIchtung be used by certain valves are opened or closed accordingly.
    After a predetermined period of use, a predetermined number of 5 return cycles of the filter aid or determination of the loss of sufficient effect of the filter aid filter aid and separated from the raw gas components are conveyed via a second line which is connected to the intermediate collection container in a separate collection chamber and stay in it. The collecting chamber should be so close that an undesired escape of filter aid and separated
    Components or access to it is not possible. The collection chamber can be replaced in the filled state against an empty collection chamber. A remote full collection chamber can be either supplied to a suitable safe disposal or recycled to the manufacturer, who can safely dispose of the contents and re-use the re-emptied Sam melkammer a reuse.
    A collection chamber should be closed in such a way that unauthorized opening is prevented or made considerably more difficult. For example, 20 special keys or tools may be required.
    As filter aids already conventionally used, e.g. Aluminum-soda-mix or trass can be used. 25 The leadership and return of filter aid can advantageously be done by Un terdrück. In this case, valves can be opened and closed, so that the return line from the intermediate collecting container is connected to the intake side of the compressor of the suction device when a return is to take place. It can be used while the Venturi Prlnzip. Sinnge-30 measure this can also be achieved in the transfer of filter aid with separated Be constituents from the intermediate header into the sump through the second line. In this case, the air flow should be influenced so that at a time only a promotion from the intermediate collection container in the filter chamber or in the collection chamber is lent. 16/04/2014 16:13 5/11 No .: R061 P.007 / 014 16/04 2014 WED 16:09 FAX 00423 265 33 01 PPR AG ÖPA 0008/014 ·· ·· ·· ···· · ···· · # »« ·· ··· · · · · · · · · · · · · ················································································· ···· 5
    A filter chamber may be formed as a Schwebstofffllter. It can also be used one or two filter cartridge (s) as a filter in a filter chamber into which the raw gas introduced and on the wall, the settling and adhering filter aid and to be separated 5 components.
    The detachment of filter aid and separated components from the inner wall of the filter chamber or a filter can advantageously be effected by means of pneumatic pressure surge. Such a pressure surge should be conducted in the opposite direction to the filter chamber in relation to the flow direction of the raw gas. The use of such pressure surges in the filtration has been quite common, so that it can be used for Known Back. A filter aid dosing device may be connected to the return line, the raw gas inlet and / or the filter chamber. When feeding to filter aid in the sucked raw gas, the respective amount depending on the intake volume flow of crude gas can be controlled. Following an inlet device for the raw gas in the Absaugeinrich device can be a pre-separator for larger particles contained in the raw gas and in turn following a filter aid dosage, with the filter aid to the raw gas can be supplied, arranged. Pre-purified exhaust gas emerging from the filter chamber can be supplied to at least one further storage filter stage. For this purpose, one or more filters can be used, which are filled with activated carbon as the filter medium, for example. Several filters can be used in the flow direction in a row arrangement. 30
    The invention will be explained in more detail by way of example in the following.

    The example shown is formed with three modules. Here, the module shown here on the left contains the compressor 4, is sucked with the raw gas from the environment. The raw gas passes through the opening 6 in the here right dar-5 Asked module. In the module there is a pre-separator for larger particles, which are separated by gravitational force from the raw gas.
    The raw gas filter additive is added via a metering device, not shown, and it flows into the filter chamber 1, which is brought here in the middle 10 shown module. In the filter chamber 1, two filter cartridges l.l and 1.2 are present in the raw gas is introduced with filter aid and other components to be separated. Filter aids and components to be separated from the raw gas are deposited on the inner walls and adhere to them. This particularly concerns constituents of the raw gas which have adhesive properties and can thereby adhere to the surface together with the filter aid.
    Vertically below the filter chamber 1, an intermediate collecting chamber 2 is arranged, in the particles from the raw gas but in particular also from the 20 walls in the filter chamber 1 detached filter aid and there far re separated components from the raw gas can be stored.
    Filter aid with separated components from the raw gas are replaced at intervals of walls of the filter chamber 1 and / or the Fllterpat-25 ronen 1.1 and 1.2 and then fall into the intermediate collection container. 2
    Also preferably in temporal intervals filter aid from the inter mediate collecting chamber 2 via the return line 2.1 in the filter chamber 1 back and re-use can be supplied. The thus recirculated filter aid can be added to new raw gas and used again, as has already been described. It is achievable multiple use of the filter aid.
    Since, however, the effect of the filter aid decreases after several cycles of use or can be completely lost, a discharge of used filter aid, which is at a distance from already separated 16/04/2014 16:14 7/11 No .: R061 P.009 / 014 MI 16 * 10 FAX 00423 265 33 01 PPR AS ÖPA 0010/014
    7 th constituents can be accompanied by the raw gas required.
    If such a time or state is reached, the second line 2.2 is opened, so that filter aid and already separated components can be emptied from the intermediate collection chamber 2 and transferred into the collection chamber 3. In this case, the return line 2.1 is closed. The transfer of the filter aid with already separated components from the intermediate collection chamber 2 in the collection chamber 3 by means of negative pressure generated by means of the compressor 4 and can be utilized accordingly with appropriate control of valves.
    If the collection chamber 3 is filled, which may be the case after several cycles to be performed between the intermediate collection chamber 2 and the collection chamber 3, the collection chamber 3 can be taken out of the extraction device and replaced by a new empty collection chamber 3. Openings on a collection chamber 3 should be kept closed at least during transport. For this purpose, check valves or analogously acting closure elements can advantageously be present at openings, with which an undesired escape of filter aid and from the raw gas separated. In particular, the sticky components, can be avoided.
    In the example shown, pre-purified raw gas can already be passed out of the filter chamber 1 via further filter stages 5 with which further components or components can be separated from the raw gas. In this example, there are four filter elements, which are arranged one above the other and are flowed through successively, in each filter element activated carbon is contained, on the surface of which absorption can take place. 16/04/2014 16:14 8/11 No .: R061 P.010 / 014
