    The invention relates to a filter device for cleaning a particle-laden gas stream, having a housing for contaminated gas having housing, which further comprises at least one filter chamber, each having at least one filter element for cleaning the gas stream, wherein the housing between the inlet opening and the filter chamber further a Funkenabscheidekammer for erasing and / or deposition of spark particles.
    In the prior art a variety of filter systems are known, which are used in conjunction with air treatment systems, especially in industrial environments. In industrial plants arise, for example, when grinding or welding metal parts, dust and other particles with high heat energy, so-called spark particles. The filter elements are usually made of fabrics which can be damaged by the sparks. In particular, the spark particles may burn holes in the fabric filters or set them on fire. The use of a spark arrester is intended to prevent the spark particles from reaching the filter elements or at least lowering their energy content to such an extent that the filter elements are not damaged.
    For spark arresting, pre-separators are used in the prior art, which are structurally separated from the actual filter system. In particular axial cyclones are used, which in principle provide satisfactory results. A disadvantage of the upstream of an axial cyclone, however, is the fact that due to the length of the axial cyclone, the footprint of the filter system must be substantially increased. In industrial plants, however, the available space is often very limited, in particular the need for floor space is critical. Thus, such pre-separators can not be used in many industrial facilities with limited space.
    In addition, it has already been proposed in the prior art to integrate the spark plugs in the housing of the filter system. In WO 2010/048647 Al a generic filter system is described, in which the air flow with the aid of
    H® 2
    Bag filters is cleaned. In addition, it is mentioned that the filter housing can be formed by queuing a cross-sectionally substantially U-shaped plate assembly on the raw gas side of the filter device a pre-separation chamber for spark arrest.
    In this case, it is also known to introduce the exhaust air vertically downwards into the pre-separation chamber and to divert it, for example by means of a deflection plate, in the horizontal direction, so that part of the spark particles is separated before the exhaust air reaches the filter modules. However, this design has proven to be less efficient in practice. In addition, it is disadvantageous in this construction that the supply of the exhaust air into the pre-separation chamber takes place in a different flow level than the supply of the filter modules.
    In contrast, the object of the present invention is to increase the efficiency of the spark deposition in a filter device of the type mentioned, wherein the space required for the spark plating base should be kept as low as possible.
    According to the invention, the spark removal chamber of the present filter device has a substantially vertically aligned impact element, wherein at least one lateral passage opening is provided adjacent at least one longitudinal edge of the impact element, so that a substantially horizontal gas flow impinging on the impact element in substantially the same horizontal plane along the impact element deflectable and can be guided through the passage opening in the direction of the filter chamber.
    The raw gas passes in the form of a horizontal flow over the particular vertically extending inlet opening into the spark deposition chamber, which is housed together with the filter chamber in a common housing. Accordingly, the spark separation chamber is - without leading out of the housing connecting line - directly with the filter chamber in gas-conducting connection. Advantageously, hereby the base area of the filter device can be reduced compared to the prior art, which, due to connecting lines between the spark separator and the filter system, has a much larger space requirement at a comparable deposition rate. Opposite the inlet opening, the impact element is arranged, which is oriented substantially perpendicular to the flow direction of the inflowing gas. Due to the impact of the raw gas on the impact element, the spark particles entrained in the gas flow are partially lowered in temperature, i. cleared, so that the sensitive components of downstream in the flow direction filter chamber, in particular any fabric filters, are protected from damage. In addition, the spark particles can also be partially separated from the gas flow with the aid of the impact element, so that these spark particles do not enter the filter chamber. For the deposition of the spark particles can advantageously be used, the vertical extent of the impact element, which may be much larger than the horizontal extent of the impact element due to the height of the, usually vertically suspended, filter elements. The lateral arrangement of the passage opening adjacent to the baffle plate causes the flowing gas in the horizontal plane can be guided in the same horizontal plane along the surface of the impact element and deflected about the longitudinal edge of the impact element. Accordingly, the gas can be guided in horizontal flow through the spark separation chamber in the direction of the filter chamber. This is particularly advantageous when a distribution channel supplying several filter chambers, as usual, is acted upon in the horizontal flow plane with the gas from the spark separation chamber. Advantageously, therefore, the flow plane is not changed by the upstream of the Funkeabscheidekämmer, whereby the flow direction and thus the flow distribution in the filter is not affected. In order to effect the most efficient diversion of the gas flow, it is favorable if the impact element and the lateral passage opening extend substantially over the entire height of the spark deposition chamber. Accordingly, the entire height of the spark deposition chamber can be used to deposit the spark particles before the gas flow is passed on in the direction of the filter chamber. Thus, high volumes of gas can be transported. Preferably, the spark separation chamber is elongated in the vertical direction. This design corresponds to the vertical orientation of the filter chambers, which usually house vertically arranged bag filters as filter elements. In this case, the - for the filter chamber anyway required - height can be used for a particularly efficient spark arrest.
    The efficiency of the spark deposition can be further improved if the Abscheidekämmer two lateral passage openings, at the opposite longitudinal edges of the impact element has. Accordingly, the inflowing gas is divided by the impact on the baffle element into two partial flows, which are guided in opposite directions in a horizontal plane along the surface of the impact element, before the partial flows are deflected at the opposite longitudinal edges of the impact element in the direction of the filter chamber. Thus, flow channels are provided on both sides of the impact element, so that the length of the spark deposition available for the sections of the impact element compared to a design in which only one of the two longitudinal edges is used, is substantially doubled. Advantageously, the efficiency of the spark separation can be substantially increased hereby.
    For separating spark particles from the gas stream, it is favorable if the impact element, preferably along its longitudinal edge, has a separating element projecting from the main plane of the impact element for separating spark particles from the gas stream. The separation element is arranged transversely to the flow direction of the gas flow, which is guided along the surface of the impact element facing the inlet opening. As a result of the impact on the separation element, the spark particles are slowed down, so that the spark particles, in particular under the effect of gravity, can be separated from the gas flow, while the gas flow is forwarded in the direction of the filter chamber. Hereby, damage to downstream in the flow direction filter elements can be reliably avoided by spark particles.
    The deposition of the spark section can be made particularly efficient when the separation element extends substantially over the entire height of the spark deposition chamber. Prior to 5
    teilhafterweise, therefore, the entire height of the Spark Abscheidekaxnmer be used for the deposition of spark particles.
    In order to remove the spark particles from the spark separation chamber, it is advantageous if the separation element has a groove-shaped separation channel. The groove-shaped separation channel preferably has a substantially U-shaped cross section, which is open against the flow direction of the gas flowing along the surface of the impact element. With the help of the groove-shaped separation channel, the spark particles can be reliably removed from the spark deposition chamber. To form the groove-shaped separation channel, an angle strip is preferably provided, which is connected at the side facing the inlet opening with the longitudinal edge of the impact element.
    With regard to a structurally simple, stable design, it is also advantageous if the separation element is formed integrally with the impact element. In this embodiment, the separation element is an integral part of the impact element, whereby the manufacturing and assembly costs can be kept particularly low. Alternatively, it would also be possible to produce the separator element as a separate component and to fasten it to the baffle element.
    It is particularly advantageous if a plate is provided as a baffle element whose longitudinal edge is bent or bent to form the separating element of the main plane of the plate. Preferably, the longitudinal edge of the plate is bent by substantially 180 ° (or two times by 90 °), whereby a groove-shaped separation channel is formed.
    According to a particularly preferred embodiment, it is provided that the spark separation chamber are connected to a discharge funnel and the filter chamber is connected to a dust collection funnel for the particles separated from the gas flow, the dust collecting funnel of the filter chamber and the discharge funnel of the spark separation chamber being assigned a common discharge device for removing the particles , Accordingly, the
    m
    6 at filter systems usually already existing discharge device are used at the same time for the removal of the collected particles in the Funkeabscheidekammer. Advantageously, it is thus possible to dispense with a separate discharge device for the spark separation, which would be absolutely necessary, for example, in an embodiment of the spark arrester as an axial cyclone. The formation of the funnel-shaped discharge members and the AustragsVorrichtung is prior art, so that more detailed explanations can do it unnecessary.
    As a discharge, for example, a screw conveyor can be provided.
    In order to transport the gas stream freed from spark particles into the filter chamber, it is favorable if the spark separation chamber has an outlet opening on the side of the impact element facing away from the inlet opening which communicates with the filter chamber, in particular via a distributor channel for distributing the gas stream to a plurality of filter chambers , communicates.
    The distribution channel is used for uniform loading of the filter chambers with the raw gas. Preferably, the filter chambers are arranged in several rows of two filter chambers, which are supplied via the central distribution channel. In this embodiment, it is particularly advantageous if the central axis of the outlet opening substantially corresponds to the central axis of the inlet opening of the spark separation chamber, so that the gas stream is guided in substantially the same horizontal plane between the inlet and the outlet opening.
    According to a particularly preferred embodiment, it is provided that the spark separation chamber is connected via the outlet opening directly to the distribution channel. Accordingly, no connecting leads leading out of the housing are provided between the spark deposition chamber and the filter chamber. Advantageously, the base area of the filter device can hereby be reduced so that the filter device can advantageously also be used in limited space conditions.
    For the efficient separation or extinguishment of the spark particles, it is particularly advantageous if the spark separation chamber has an air gap in the chamber
    meem
    Cross-section substantially U-shaped flow channel around the longitudinal edge of the impact element, so that the gas flow in the Funkeabscheidekämmer is deflected by substantially 180 °. This embodiment has the advantage that those portions of the spark particles contained in the gas stream, which are not separated by means of the separating element, when impacting the Funkeabscheidekammer meet several times on impact surfaces of the flow channel limiting housing wall, whereby the temperature of the particles remaining in the gas stream reliably to a for the Filter element uncritical level can be lowered.
    Moreover, it is advantageous if the spark deposition chamber has at least one further separating element on a housing wall delimiting the U-shaped flow channel inwardly. Accordingly, at least one further separation element is provided on the outside of the flow channel, whereby the yield of the spark deposition is further increased.
    In this embodiment, it is particularly advantageous if the at least one further separation element is arranged adjacent to the exit opening of the spark deposition chamber, wherein preferably one further separation element is disposed on both sides of the exit opening. Accordingly, in this embodiment, further separation elements are provided next to the exit opening of the Funkeab excretion chambers. Hereby, the proportion of the separated from the gas stream spark particles can be further increased.
    With regard to a particularly compact design of the filter device, it is particularly advantageous if the spark separation chamber and the filter chamber are arranged side by side at substantially the same height. In particular, the spark deposition chamber does not project beyond the filter chamber in the vertical direction. Advantageously, therefore, the height is not increased by the arrangement of the spark deposition chamber over a design without spark deposition. This represents a significant advantage over filter systems, in which the spark arrester and the filter housing are mounted at different height levels, which are connected to each other via pipes.

    In addition, it is particularly preferred if the spark deposition chamber has a smaller or essentially the same height as the filter chamber. Advantageously, the same modules or modules of similar construction can therefore be used for the spark separation chamber and the filter chamber.
    The invention will be explained below with reference to an embodiment shown in the figures, to which, however, it should not be limited. In detail, in the drawing:
    1 is a perspective view, partly in section, of a filter device according to the invention, which has filter chambers arranged in rows and a spark separation chamber with a baffle element;
    Figure 2 is a schematic sectional view of the filter device of Figure 1 taken along the line II-II in Figure 1, wherein a second series of filter chambers is visible ..;
    Fig. 3 is a schematic sectional view of the filter device according to
    Figure 1 along the line III-III in Fig. 1.
    Fig. 4 is a schematic sectional view of the filter device according to
    Fig. 1 along the line IV-IV in Fig. 1; and
    Fig. 5 is a perspective view of an alternative filter device with a single filter chamber.
    Fig. 1 to 4 shows a filter device 1 for cleaning a particle-laden gas stream, which has arisen in an industrial plant, such as a steel plant. The gas stream is loaded with a variety of particles, in particular dust, with a proportion of spark particles, i. Particles with high heat energy, is present.
    As can be further seen from FIGS. 1 to 4, the filter device 1 has a filter housing, hereinafter referred to as housing 2, which has an inlet opening 2 'for the gas flowing in the horizontal direction 3. For cleaning the gas flow
    9, the housing 2 in the embodiment shown, two rows of filter chambers 4, 4 '. Alternatively, a single-row filter device 1 can also be provided (compare FIG. 5). The housing 2 further has a central distribution channel 18 which extends between the opposing filter chambers 4 and 4 '. The distribution channel 18 is connected via supply openings 19 with the torture chambers 4, 4 ', so that the raw gas stream passes in the direction of arrow 7 into the filter chamber 4.
    As can be further seen from Figures 1, 2, the filter chambers 4 and 4 'each have a plurality of filter elements 5; in Fig. 1, for better clarity, only a single filter element 5 is located. In the embodiment shown, the filter elements 5 are designed as a bag filter, which are arranged in a vertical orientation in the filter chambers 4 and 4 '. For cleaning industrial exhaust gases on a large scale, the filter elements 5 have a height of at least 3 meters. The filter elements 5 are acted upon from the outside with the gas stream to be cleaned, wherein the entrained in the gas stream particles are deposited on the lateral surface of the filter elements 5. The filter elements 5 may be connected to, not shown in the drawing, cleaning devices, which allow cleaning of the filter elements 5. The purified gas flows upward in the vertical direction 7 'within the filter elements 5. The upper ends of the filter elements 5 are in this case connected to the clean gas chambers 6 and 6 ', so that the gas stream passes from the interior of the filter elements 5 into the clean gas space 6. The purified gas stream flows through the clean gas space 6, 6 'in the direction 7'1, enters the clean gas channel 27 and leaves the housing 2 of the filter device 1 via an outlet opening (not shown).
    As can be further seen from Figs. 1 to 4, the filter chambers 4 and 4 'are connected at the bottom with Staubsammmeltrichtern 9, in which the deposited particles are collected.
    The dust collecting funnels converge conically downwards. The Staubsammmeltrichtern is associated with a discharge device 10, with which the particles are taken from the Staubsammmeltrichtern 9 and transported away. The discharge device 10 is in this case designed as a screw conveyor.
    10
    As is further apparent from FIGS. 1 to 4, the filter device 1 has a spark arrestor chamber 11 integrated into the housing 2, with which the spark particles contained in the gas flow are extinguished or separated. The spark separation chamber 11 is arranged between the inlet opening 2 and the filter chambers 4 and 4 ', so that the spark separation chamber 11 is set up as a pre-separator. The spark separation chamber 11 is adapted to separate the spark particles entrained in the gas flow from the gas flow and / or to lower the temperature of the spark particles in such a way that the filter elements 5 of the filter chambers 4 and 4 'acted upon by the gas flow are not damaged.
    As can be further seen from FIGS. 1 to 4, the spark arrester carcasses 11 and the filter chambers 4 and 4 'are arranged side by side in the same housing 2. In addition, the spark separation chamber 11 and the filter chambers 4 and 4 'substantially the same height, wherein the filter chambers 4 and 4' by the height of the clean gas space 6 are higher than the spark separation chamber 11. Advantageously, therefore, similar housing modules can be used for the spark separation chamber 11 and the filter chambers 4 and 4 ', the arrangement of the filter separation chamber 11 not increasing the overall height of the filter device 1 as a whole.
    As is further apparent from FIGS. 1 to 4, the spark deposition chamber 11 has a substantially vertically aligned impact element 12, which is arranged substantially perpendicular to the gas flowing in the horizontal direction 3. The impact element 12 is designed as a plate, which is arranged substantially perpendicularly in the spark separation chamber 11, opposite the inlet opening 2 '. The arrangement of the impact element 12 causes the substantially horizontal gas flow impinging on the impact element 12 to be divided into two partial flows 15 and 15 ', which are guided in opposite directions in a horizontal plane along the surface of the impact element 12. As a result of the impact on the impact element 12, the spark particles contained in the gas flow are at least partially extinguished.
    11
    As can also be seen from FIGS. 1 to 4, the spark arresting chamber 11 also has lateral passage openings 13 and 13 ', which adjoin the opposite longitudinal edges 14 of the impact element 12. The partial flows 15 and 15 'of the gas flow are deflected around the longitudinal edges 14 of the impact element 12 (see arrows 15'), wherein the partial flows 15 and 15 'pass through the passage openings 13 and 13'. The passage openings 13 and 13 'in this case extend essentially over the entire height of the spark separation chambers 11, so that comparatively large flow volumes can be conducted via the passage openings 13 and 13' in the direction of the filter chambers 4 and 4 '.
    As is further apparent from FIGS. 1 to 4, the spark deposition chamber 11 has substantially U-shaped flow channels 16 and 16 'in cross-section at the opposite longitudinal edges 14 of the impact element 12, the gas flow essentially being passed through the flow channels 16 and 16' 180 ° is deflected. In addition, the spark deposition chamber 11 has an outlet opening 17 on the side of the impact element 12 facing away from the inlet opening 2 ', which outlet opening extends in the vertical direction over substantially the entire height of the spark deposition chamber 11. The outlet opening 17 is directly connected to the central distribution channel 18, which divides the gas flow to the opposite filter chambers 4 and 4 '.
    As best seen in Fig. 1, separator elements 20 are provided on the longitudinal edges 14 and 14 'of the baffle element 12 in the illustrated embodiment, which are arranged to separate spark particles from the gas stream. The Äbschei-deelemente 20 are opposite to the flow direction of the flowing at the surface of the impact member 12 partial streams 15 and 15 'oriented, so that the partial streams 15 and 15' impinge against the separation elements 20. As a result of the impact on the separation elements 20, the spark particles are decelerated and fall down under the effect of gravity. The separation elements 20 extend essentially over the entire height of the spark separation chamber 11.
    As can be seen from Fig. 1 further, the AbScheideelement
    iPrinted: 21-12-2012 12 20 a groove-shaped separation channel 21 on. The separation channel 21 adjoins the impact element 12. In this case, the separation element 20 is arranged on the side of the impact element 12 facing the inlet opening 2 '. In the embodiment shown, the separation element 20 is formed integrally with the longitudinal edge 14 of the impact element 12. To form the Abscheidelements 20, the longitudinal edges 14 of the plate-shaped impact element 12 are bent.
    As is further apparent from FIGS. 1 and 2, the spark arrestor chamber 11 is connected to two discharge hoppers 23, which are funnel-shaped in accordance with the dust collecting funnels 9 of the filter chambers 4 and 4 '. The discharge hoppers 23 are arranged opposite one another below the spark deposition chamber 11. In this case, the impact element 12 extends as far as the lower end regions of the discharge funnels 23, wherein the separation elements 20 of the impact element 12 protrude into the vicinity of the lower end regions of the discharge funnels 23. In addition, 23 vertical separating elements 25 are arranged in the discharge hoppers, which are arranged substantially perpendicular to the main plane of the impact element 12 aligned with the longitudinal edges 14 and 14 'of the impact element 12. The separating elements 25 prevent the gas streams from entering the discharge funnels 23 and resuming already separated particles there.
    As can be further seen from FIGS. 1 to 4, the discharge funnels 23 of the spark separation chamber 11 and the dust collection funnels 9 of the filter chambers 9 are connected to the discharge device 10, so that the particles deposited in the spark separation chamber 11 and those in the filter chambers 4 and 4 '. deposited particles are transported together for further processing or disposal.
    As can be further seen from FIGS. 1 to 4, the spark arresting chamber 11 has further separating elements 20 ', which are formed on the housing walls 25' of the spark deposition chamber 11, which delimit the U-shaped flow channels 16 and 16 'inwards. In the embodiment shown, the further separation elements 20 'are arranged adjacent to the outlet opening 17 of the spark deposition chamber 11, the opposite side being the one
    13
    Output opening 17 each have a further separating element 20 'is provided. The further separation elements 20 'are aligned in a substantially vertical direction, parallel to the separation elements 20 of the impact element 12. As separation elements 20 'as the separation elements 20 are designed as angle strips, which are oriented counter to the flow direction of the gas flow. For separating spark particles, the further separation elements 20 'each have a groove-shaped separation channel 21' which leads into the associated discharge element 23 below the spark deposition chamber 11.
    Fig. 5 shows an alternative embodiment of the filter device 1, which largely corresponds to the previously described embodiment, but in which only a single filter chamber 4 is provided.
