Abstract
Description
Technical Field
[0001] This disclosure relates to a wall module for dry separation of particulate matter in exhaust gas in a treatment device (particularly in the air passage of the treatment device); a treatment device (particularly for dry separation, particularly for dry separation of paint) having a passage for guiding exhaust gas, the passage having a wall module; and a method for modifying the passage of the treatment device from wet separation of particulate matter in exhaust gas to dry separation via the wall module. Background Technology
[0002] It is known to construct treatment equipment with channels (especially air channels) in a modular manner, particularly for equipment used to separate particulate matter (especially paint, such as paint in vehicle painting equipment) from exhaust gases.
[0003] The channel typically consists of multiple sections, which are assembled and welded together on-site at the processing equipment's work site. Most sections are composed of hollow profiles, which are connected to various plates.
[0004] For economic and / or ecological reasons, painting equipment has been partially converted from wet separation of particulate matter in exhaust gas to dry separation.
[0005] When converting a painting equipment from wet separation of particulate matter in exhaust gas to dry separation, the separation chamber of the wet separation section, which contains a so-called venturi separator and demister, is usually completely removed below the gitterrostebene to make room for the construction of the dry separation section. Typically, cranes or other auxiliary tools must be used for larger sections.
[0006] Due to their complexity and associated high costs, retrofit plans are often rejected at the last step. If a common dry separation rack is used, a maintenance passage must be planned between the rear of the rack, the filter box, the installation location of the color-blocking pad, and the filter wall. The bag filters of the filter wall are replaced from the raw gas side through this maintenance passage when necessary.
[0007] Such renovations are time-consuming and material-intensive, both of which contribute to high costs. Therefore, production stoppages caused by downtime due to lengthy or delayed renovations should be avoided as much as possible.
[0008] Public content The purpose of this disclosure is to provide an improved wall module for dry separation of particulate matter in exhaust gas in a treatment device (particularly in the air passage of the treatment device).
[0009] Another object of this disclosure is to provide a treatment apparatus, particularly an apparatus for dry separation, especially an apparatus for dry separation of paint, the treatment apparatus having a channel for guiding exhaust gas, the channel having an improved wall module.
[0010] Another object of this disclosure is to provide an efficient method for converting the channel of a treatment device from wet separation of particulate matter in exhaust gas to dry separation via an improved wall module.
[0011] The above-mentioned objectives are achieved by the features of the independent claims. Advantages and advantages of this disclosure are derived from the other claims, the description, and the drawings.
[0012] According to one aspect of this disclosure, a wall module is proposed for dry separation of particulate matter in exhaust gas in a treatment device, particularly in the air passage of the treatment device. The wall module has a transverse, longitudinal and vertical orientation, and a base frame extending in the transverse and vertical directions through its perforations. At least one frame element for accommodating one or more filter elements is connected to the base frame, wherein, in particular, at least one frame element abuts against the base frame.
[0013] The proposed wall module enables a simple retrofit of treatment equipment from wet separation to dry separation of particulate matter in exhaust gas without relying on the original manufacturer of wet separation equipment, and can be used in common wet separators.
[0014] This wall module allows for minimally invasive modifications. Dismantling of the treatment equipment is limited to the venturi separator and demister. The basic structure of the treatment equipment remains unchanged and is reused, including the outer wall, bottom, and inlet geometry of the venturi separator.
[0015] This eliminates the need for on-site welding. Blind rivet nuts and pins are sufficient for simple installation of the wall modules.
[0016] Advantageously, a scheme for efficient installation of wall modules can be implemented. Therefore, modifications can begin on both sides of the exhaust duct of the processing equipment, and the various modification steps can be carried out by multiple teams in a staggered manner while continuing to use the existing exhaust duct.
[0017] The wall module can advantageously feature a modular design, where components, such as two or more frame elements, can be pre-installed, interlocking and equipped with or potentially equipped with filter elements. Each component weighs less than 40 kg, allowing two people to operate it ergonomically without the use of additional tools.
[0018] Using the proposed wall modules, a compact configuration can be achieved with mutually cooperating and fluid technology-optimized filtration stages (e.g., filter boxes, filter pads, and bag filters). For example, the first frame element can have at least one filter box, the second frame element can have at least one filter pad, and the third filtration element can have at least one bag filter. The filter pad can be a so-called color-blocking pad.
[0019] The bag filter can be installed and removed on the clean gas side with this design. No maintenance access is required between the filter pad and the bag filter in the treatment equipment.
[0020] Advantageously, the intake velocity of the exhaust gas can be optimized by flexibly adjusting the number of bag filters used (e.g., in the first frame element). Similarly, the sequence of different filter elements arranged sequentially in the flow direction can be adjusted as needed.
[0021] Wall components can also be directly integrated into the new channel structure when needed.
[0022] Advantageously, the total pressure drop of the exhaust gas in the treatment equipment is smaller in the proposed wall module than in the existing venturi separator with a demister. Therefore, the existing channels and air equipment can be used in the first step. Consequently, a high-efficiency dry separation section can be constructed in the second step.
[0023] According to an advantageous embodiment of the wall module, a second frame element for accommodating at least one filter element can be longitudinally connected to a first frame element, specifically, the second frame element abuts against the first frame element. Therefore, the wall module can be advantageously configured as modular.
[0024] According to an advantageous embodiment of the wall module, a third frame element for accommodating at least one filter element can be longitudinally connected to a second frame element, specifically, the third frame element abuts against the second frame element. Therefore, the wall module can be advantageously configured as modular.
[0025] According to an advantageous embodiment of the wall module, the airflow direction can extend from the base frame through at least one frame element under normal conditions. Specifically, the airflow direction can extend from the base frame through the first frame element, the second frame element, and the third frame element under normal conditions. This allows for efficient purification of the exhaust gas from the treatment equipment.
[0026] According to an advantageous embodiment of the wall module, at least one filter element may have one of the following components: a filter box, a filter pad, or a bag filter. This allows for efficient purification of the equipment's exhaust gas.
[0027] According to an advantageous embodiment of the wall module, at least one filter element can be arranged to extend laterally and vertically and to be fluid-tightly connected to at least one frame element.
[0028] Specifically, at least one filter box in the first frame element can be arranged to extend laterally and vertically and be fluid-tightly connected to the first frame element. This advantageously allows for pre-separation of particulate matter in the exhaust gas.
[0029] Furthermore, in particular, at least one filter pad in the second frame element can be arranged to extend laterally and vertically and be fluid-tightly connected to the second frame element. Such a filter pad can be, for example, a so-called color-blocking pad to remove pigment particles from the exhaust gas.
[0030] Furthermore, at least one bag filter can be arranged to extend laterally and vertically and be fluid-tightly connected to the third frame element, wherein at least one bag filter extends longitudinally outward from the third frame element. The bag filter for separating fine particles from exhaust gas can be modularly mounted in the third frame element.
[0031] According to an advantageous embodiment of the wall module, at least one filter element can be installed opposite to the flow direction under normal conditions and removed in the same direction. This allows for easy replacement of at least one filter element, for example, when it is fully loaded. This is particularly advantageous when multiple individually replaceable frame elements, each having one or more filter elements, are connected to each other.
[0032] According to an advantageous embodiment of the wall module, the base frame and at least one frame element are screwed, glued, or welded together. This allows for simple and flexible on-site installation of the wall module within the processing equipment. In particular, bolting simplifies the installation of the wall module, as no complex tools are required.
[0033] According to an advantageous embodiment of the wall module, at least one frame element is formed from a folded plate (Kantblechteil). Specifically, at least one frame element can be formed from a thermoplasticized steel sheet with a thickness of at least 1 mm, preferably at least 2 mm. This method allows for the cost-effective manufacture of the wall module components. The weight of the components also allows for on-site installation by two people without the need for larger auxiliary tools.
[0034] According to an advantageous embodiment of the wall module, multiple filter elements capable of parallel flow can be simultaneously arranged in at least one frame element, particularly when the filter elements are in the form of filter boxes and / or bag filters. Advantageously, when multiple successive frame elements exist, at least one frame element can have filter elements capable of parallel flow, while other frame elements can have only one filter element. This allows for effective coarse filtration of exhaust gases. When the first frame element has a square cross-section, nine filter boxes can be arranged simultaneously, exemplarily. Advantageously, standardized bag filters can also be used. When the frame element, particularly the third frame element, has a square cross-section, four bag filters can be arranged side by side, exemplarily.
[0035] According to an advantageous embodiment of the wall module, at least one bottom balancing element and / or top balancing element can be vertically arranged at the base frame, with the balancing elements protruding from the permeable openings of the base frame. In this way, the wall module can be easily inserted into existing treatment equipment and provides advantageous guidance for exhaust gases.
[0036] According to another aspect of this disclosure, a treatment apparatus is proposed, particularly an apparatus for dry separation, especially an apparatus for dry separation of paint, the treatment apparatus having at least one channel for guiding exhaust gas, the channel having at least one wall module, wherein the at least one wall module is arranged on or inside the sidewall of the channel.
[0037] The proposed treatment apparatus can advantageously include at least one wall module as described above for dry separation of particulate matter (particulate matter, particularly paint) from exhaust gas. The treatment apparatus can advantageously be converted from wet separation to dry separation via at least one wall module. For common wet separators, this conversion can be made independently of the original manufacturer of the wet separation section via the wall module.
[0038] The wall module has a modular design, with parts pre-installed.
[0039] A compact construction of filtration stages (e.g., filter boxes, filter pads, and bag filters) that are mutually compatible and optimized for fluid technology can be achieved through at least one wall module.
[0040] In this design, the bag filter can be installed and removed from the clean gas side. No maintenance access point within the processing equipment is required between the filter pad and the bag filter.
[0041] Advantageously, when using multiple filter boxes, there is flexibility to optimize the exhaust gas intake velocity.
[0042] When needed, the wall modules can also be directly integrated into the new channel structure.
[0043] The total pressure drop of the exhaust gas in the treatment equipment is advantageously lower in the wall module than in the wet separation section with a venturi separator.
[0044] According to an advantageous embodiment of the treatment equipment, at least one wall module can be directly integrated into or form the sidewall of the channel via its basic frame. This allows for efficient filtration and favorable flow guidance of the exhaust gas.
[0045] According to an advantageous embodiment of the treatment equipment, multiple wall modules can be integrated into or form the sidewalls of the channel in a manner that allows them to flow through in parallel. Specifically, every two wall modules in the channel can be arranged opposite each other via their basic frame, and / or multiple wall modules can be arranged side-by-side in the sidewalls. This allows for the combination of a compact design of the treatment equipment with highly efficient filtration of exhaust gases.
[0046] According to an advantageous embodiment of the processing equipment, the sidewalls of the passage may at least partially have one or more gates. Specifically, the sidewalls of the passage may at least partially have one or more gates capable of being flipped to a horizontal position. In particular, the sidewalls of the passage may at least partially have one or more gates that, when horizontally flipped open, obstruct the passage relative to the processing chamber or relative to the bottom.
[0047] To facilitate better maintenance and, possibly, to allow for filter replacement during production, the sidewalls in the channel opposite at least one wall module can be designed to be at least partially folded open, depending on the percolation method of the exhaust gas, thereby creating a partition and allowing access to the filter box from the outside.
[0048] According to an advantageous embodiment of the processing equipment, the wall module can be moved longitudinally, particularly on rollers, for the purpose of replacing at least one filter element, especially for the purpose of replacing the filter box.
[0049] When the wall components are isolated from the original gas flow by flipping the sidewalls, the wall modules can be designed to move forward along a track on rollers, allowing the filter box to be replaced completely outside the paint mist of the exhaust gas.
[0050] To improve the isolation of the wall module, other gates that also block gas flow in the lateral direction can be installed.
[0051] According to another aspect of this disclosure, a method is proposed for modifying a channel of a treatment device from wet separation of particulate matter in exhaust gas to dry separation via an improved wall module. The method includes at least the following steps: capturing the top of a venturi device of the wet separation section of the channel by a capturing element; removing the venturi device; installing a base frame of the wall module; removing the droplet condensation wall of the channel; installing at least one frame element of the wall module for accommodating one or more filter elements to the base frame; and equipping the at least one frame element with at least one filter element.
[0052] The proposed method advantageously enables a simple retrofit of a treatment device from wet separation to dry separation of particulate matter in the exhaust gas without relying on the original manufacturer of the wet separation unit, and can be used with common wet separators.
[0053] The wall module features a modular design with pre-installed parts. Each part weighs less than 40 kg, allowing for ergonomic operation by two people without additional tools.
[0054] This wall module allows for minimally invasive modifications. Demolition work is limited to the venturi separator and demister. The basic structure of the treatment equipment remains unchanged and is reused, including the outer wall, bottom, and inlet geometry of the venturi separator.
[0055] This eliminates the need for on-site welding. Blind rivet nuts and pins are sufficient for simple installation of the wall modules.
[0056] Advantageously, a scheme for efficient installation of wall modules can be implemented. Therefore, modifications can begin on both sides of the exhaust duct of the processing equipment, and the various modification steps can be carried out by multiple teams in a staggered manner while continuing to use the existing exhaust duct.
[0057] The use of wall modules allows for the creation of compact structures with interlocking and fluid technology-optimized filtration stages, such as filter boxes, filter pads, and bag filters.
[0058] The bag filter can be installed and removed from the clean gas side with this design. No maintenance passage is required between the color-blocking pad and the bag filter.
[0059] Advantageously, when using multiple filter boxes, there is flexibility to optimize the exhaust gas intake velocity.
[0060] Wall components can also be directly integrated into the new channel structure when needed.
[0061] Advantageously, the total pressure drop of the exhaust gas is smaller in the wall module than in the existing venturi separator with a demister. Therefore, the existing channels and air equipment can be used in the first step. Consequently, a high-efficiency dry separation section can be constructed in the second step.
[0062] According to an advantageous embodiment, the method may further include: mounting a second frame element of at least one frame element of the wall module onto the first frame element and equipping the second frame element with at least one filter element. This allows the wall module to be advantageously configured as modular.
[0063] According to an advantageous embodiment, the method may further include: mounting a third frame element of at least one frame element of the wall module onto the second frame element and equipping the third frame element with at least one filter element. This allows the wall module to be advantageously configured as modular.
[0064] For example, a first frame element may be configured to accommodate a filter box, a second frame element may be configured to accommodate a filter pad, and a third frame element may be configured to accommodate a bag filter.
[0065] According to an advantageous embodiment of the method, the capturing element may have two tubes arranged coaxially. This allows the length of the capturing element to be adapted to the size of the processing equipment when capturing the top.
[0066] According to an advantageous embodiment of the method, the base frame can be welded to the bottom of the channel and / or to the top of the venturi assembly. Specifically, in this case, the bottom balancing element of the base frame is welded to the bottom and / or the top balancing element of the base frame is welded to the top. This allows for a stable connection between the base frame and the channel structure of the processing equipment.
[0067] According to an advantageous embodiment of the method, the base frame and at least one frame element can be screwed, glued, or welded together. This allows for simple and cost-effective installation of the wall modules. In particular, bolting simplifies the installation of the wall modules in the processing equipment, as no complex tools are required.
[0068] According to an advantageous embodiment of the method, the base frame can be connected to the cut edge of the venturi device. This allows for a stable connection between the base frame and the channel structure of the processing equipment.
[0069] According to an advantageous embodiment of the method, multiple wall modules can be installed in the channel, wherein every two wall modules are arranged opposite each other in the channel, and / or multiple wall modules are arranged side by side in the sidewalls of the channel. In this way, the channel structure can be effectively expanded by integrating multiple wall modules.
[0070] According to an advantageous embodiment of the method, the installation of each pair of wall modules facing each other in the channel can begin simultaneously, with the installation steps performed at staggered times. Alternatively or additionally, the existing channels of the processing equipment can continue to be used during the installation of the wall modules. This advantageously minimizes downtime of the processing equipment and thus reduces production stoppages in the plant.
[0071] According to an advantageous embodiment of the method, the gates on the sidewalls of the channel can be at least partially flipped to replace the filter elements, particularly the filter pads and / or filter boxes. Specifically, in this case, the gates on the sidewalls of the channel can be at least partially flipped to a horizontal position to replace the filter elements, particularly the filter pads and / or filter boxes, and the processing chamber and bottom are closed relative to the wall module.
[0072] For better maintenance and possibly for replacing the filter during production, the sidewalls in the channel opposite at least one wall module can be designed to be at least partially hinged, depending on the percolation method of the exhaust gas, thereby creating a partition and allowing access to the filter box from the outside.
[0073] According to an advantageous embodiment of the method, in order to replace the filter element, especially to replace the filter box, the wall module can be moved longitudinally, particularly on rollers.
[0074] When the wall module is isolated from the original gas flow by the sidewall gates, it can be moved forward along a track on rollers, allowing the filter box to be replaced completely outside the paint mist of the exhaust gas. To improve the isolation of the wall module, other gates that also block gas flow laterally can be installed. Attached Figure Description

[0081] The wall module 100 has a horizontal dimension 110, a vertical dimension 112, and a vertical dimension 114.
[0082] The direction of airflow according to this disclosure, indicated by the arrow, extends longitudinally at 112.
[0083] The wall module 100 includes a base frame 10 extending in the transverse direction 110 and in the vertical direction 114, and at least one frame element 20, 30, 40 for accommodating filter elements 21, 31, 41 is connected to the base frame in the longitudinal direction 112, and the frame element abuts against the base frame 10 in particular.
[0084] Figure 1 and Figure 2 In the embodiment shown, the first frame element 20 for housing the filter box 22 is connected to the base frame 10 and particularly abuts against the base frame 10.
[0085] Multiple filter elements 21, particularly multiple filter boxes 22, can be arranged in parallel in the conventional flow direction 120 in the first frame element 20, so that these filter elements can be flowed through.
[0086] exist Figure 2The filter box 22 can be observed in the longitudinal section. The filter box 22 in the first frame element 20 extends in the transverse direction 110 and the vertical direction 114 respectively and is fluid-tightly connected to the first frame element 20.

[0091] In the illustrated embodiment, four bag filters 42 are arranged on the third frame element 40, extending in the transverse direction 110 and in the vertical direction 114 respectively, and are fluid-tightly connected to the third frame element. In this case, the bag filters 42 extend outward from the third frame element 40 in the longitudinal direction 112.

[0097] On the base frame 10, a bottom balancing element 12 and a top balancing element 14 protruding from the base frame 10 are arranged vertically on 114. The bottom balancing element 12 can be welded to the bottom 216 of the processing device 300, and the top balancing element 14 can be welded to the top 214 (see [reference]). Figure 11 ).

[0105] Figures 9 to 16The longitudinal section of the treatment device 300 shows the various steps of a method for converting the channel 200 of the treatment device 300 from wet separation of particulate matter in exhaust gas to dry separation by at least one wall module 100 according to an embodiment of the present disclosure.
[0106] The treatment equipment 300 has a channel 200 for guiding exhaust gas, in which various wet modules 130 are arranged in the initial state. The exhaust gas is guided to the wet modules 130 through a venturi device 212.
[0107] The processing chamber 302, equipped with the corresponding conveying technology equipment 310, is located above the channel 200, which has a wet module 130.
[0108] Channel 200 is defined by side wall 210.
[0109] Figure 9 The first step is shown for converting the channel 200 of the treatment device 300 from wet separation of particulate matter in exhaust gas to dry separation via at least one wall module 100.
[0110] First, the wet module 130 is removed. To do this, the top 214 of the venturi assembly 212 of the wet separation section of the channel 200 is captured by the capturing element 50. The capturing element 50 may, for example, have two tubes 52, 54 arranged coaxially for adjusting the length.
[0111] exist Figure 10 In the second step of the method shown, the venturi 212 is at least partially removed, a process shown by the dashed outline of the venturi device 212, which was previously a solid outline.
[0112] exist Figure 11 In the third step of the method shown, the base frame 10 of the wall module 100 is installed. In this case, the base frame 10 is connected to the cut edge 220 of the venturi device 212.
[0113] For this purpose, the base frame 10 is first installed and then welded to the structure of the processing device 300. The base frame 10 is welded to the bottom 216 of the channel 200 and to the top 214 of the venturi assembly 212. In particular, the bottom balancing element 12 of the base frame 10 can be welded to the bottom 216 and the top balancing element 14 of the base frame 10 can be welded to the top 214.
[0114] exist Figure 12 In the fourth step of the method shown, the droplet condensation wall 218 of the channel 200 is removed and the previously existing percolation device of the treatment device 300 is removed from the center.
[0115] exist Figure 13In the fifth step of the method shown, the first frame element 20 of the wall module 100 for accommodating the filter box 22 is mounted on the base frame 10.
[0116] exist Figure 14 In the sixth step of the method shown, the second frame element 30 of the wall module 100 for receiving the filter pad is mounted on the first frame element 20.
[0117] exist Figure 15 In the seventh step of the method shown, the third frame element 40 of the wall module 100 for accommodating the bag filter 42 is mounted to the second frame element 30.
[0118] The base frame 10, the first frame element 20, the second frame element 30, and the third frame element 40 can be advantageously screwed together.
[0119] exist Figure 16 In the eighth step of the method shown, the wall module 100 is equipped with a filter box 22 and / or a filter pad 32 and / or a bag filter 42.
[0120] Advantageously, each pair of wall modules 100 facing each other within the channel 200 can begin installation simultaneously and perform the installation steps separately in staggered time. Alternatively or additionally, the existing channel 200 of the processing device 300 can continue to be used during the installation of the wall modules 100.
[0121] The wall module 100 can be arranged on the side wall 210 of the channel 200. In this case, the wall module 100 is directly integrated into the side wall 210 of the channel 200, specifically integrated into the side wall 210 through its base frame 10 or forming the side wall 210 of the channel 200.
[0122] exist Figure 17 The image shows a processing device 300 according to another embodiment of the present disclosure, which has a gate 208 located within a sidewall 210.
[0123] For better maintenance and possibly for replacement of the filter during production, the sidewall 210 in the channel 200, which is opposite to at least one wall module 100, can be designed to be at least partially foldable, depending on the percolation method of the exhaust gas, thereby creating a partition and allowing access to the filter box 22 from the outside.
[0124] In this configuration, the sidewall 210 of the channel 200 at least partially has one or more gates 208. Specifically, the sidewall 210 of the channel 200 in this configuration is as follows: Figure 17 The embodiments shown may at least partially have a plurality of gates 208 capable of being opened in the horizontal direction.
[0125] exist Figure 17 The central gate 208 is represented by a solid line when the side wall 210 is closed and by a dashed line when it is open. The direction of movement of the open gate 208 is indicated by a dashed arrow.
[0126] The gate 208 can therefore block the passage relative to the processing chamber 302 and relative to the bottom 216 in a horizontally open state.
[0127] The gate 208 of the side wall 210 of the channel 200 can therefore be at least partially opened for replacing filter elements 21, 31, 41, especially filter pad 32 and / or filter box 22. In particular, the gate 208 can be at least partially opened horizontally for replacing filter elements 21, 31, 41, especially filter pad 32 and / or filter box 22 and close the processing chamber 302 and bottom 216 relative to the wall module 100.

[0129] When the wall module 100 is isolated from the original gas flow by the gate 208 of the side wall 210, the wall module 100 can be moved forward on the track on rollers, so that the filter box 22 can be replaced completely outside the paint mist of the exhaust gas. To improve the isolation of the wall module 100, other gates 208 that also isolate the air flow laterally can be installed.
[0130] Figure 18 A top view of a processing apparatus 300 according to another embodiment of the present disclosure is shown, which has six wall modules 100. Figure 19 The image shows a cross-section through the processing device 300.
[0131] The processing device has multiple wall modules 100, which are integrated into or form the sidewalls 210 of the channel 200 in a manner that allows for parallel flow through. The flow direction 120 extends outward from the channel 120 through the wall modules 100 under normal conditions.
[0132] Each pair of wall modules 100 is arranged opposite each other within the channel 200, wherein multiple wall modules 100 are arranged side by side within the sidewall 210. In this way, the channel structure can be efficiently expanded by integrating multiple wall modules 100.
