Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and specifically to a waste gas treatment device and method for color-coated plates. Background Art

[0002] Color-coated plates are produced on continuous production lines with cold-rolled strip steel or galvanized strip steel as the base plate. After surface pretreatment and by means of roll coating, one or more layers of liquid coatings are applied. The plates obtained after baking and cooling are coated steel plates. The color-coated plates after color coating have the characteristics of light weight, beauty and good corrosion resistance, and are widely used in the fields of construction, shipbuilding, vehicle manufacturing, furniture industry, electrical industry, etc.

[0003] The main production processes of color-coated plates are: uncoiling → pretreatment → coating → baking → post-treatment → coiling. In the coating and baking processes, due to the diffusibility of color coating mist, a large amount of particulate impurities, solvents, etc. mainly composed of coating mist are contained in the color-coated waste gas. The direct emission of coating mist will cause air pollution and damage to the human respiratory system. Therefore, in the production process of color-coated plates, a waste gas treatment device is needed to treat the color-coated waste gas. Since a large amount of coating mist is contained in the color-coated waste gas, the method of using a spray tower is often borrowed, and its internal filtering fillers such as multi-faceted plastic balls, Raschig rings, Pall rings, and cascade rings are used to achieve the atomization and adsorption treatment of coating mist in the color-coated waste gas.

[0004] For example, the Chinese patent with the publication number CN113209750A discloses a spray painting waste gas purification system. Such a spray painting waste gas purification system uses a water curtain spraying table to purify the inhaled waste gas, then uses a pre-filter to pre-filter the waste gas, a spray tower to spray and filter the waste gas, a photo-oxygen purifier to carry out photo-oxygen purification on the waste gas, and finally uses an activated carbon adsorption box to carry out activated carbon adsorption and filtration on the waste gas.

[0005] However, during the process of filtering and intercepting the coating mist in the spray painting waste gas by the spray tower, after each filtering treatment, a large amount of coating mist impurities and residual water mist containing impurities often remain in its fillers. After long-term retention and adhesion, the filtering and intercepting characteristics of the filtering fillers are greatly reduced, and the effectiveness of the spray filtering treatment of the coating mist in the waste gas is extremely slowed down. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a waste gas treatment device and method for color-coated plates, which solves the problems raised in the background art.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: a waste gas treatment device and method for color-coated plates.

[0008] On the one hand, the present invention provides a color-coated board waste gas treatment device, including: a spray tower; a packing orifice plate, which is provided with at least one group, and the packing orifice plate is placed inside the spray tower.

[0009] Furthermore, it further includes a first bracket arranged inside the rotating shell. A rotating shaft is arranged in the middle of the first bracket. There is a spring between the first bracket and the rotating shaft. One end of the rotating shaft is provided with a rotating seat, and the rotating seat is provided with at least one group of arm force push rods along its circumferential direction.

[0010] Furthermore, it further includes a transmission frame arranged inside the transmission belt. Transmission rollers for tensioning and driving the transmission belt to rotate are arranged at both ends of the transmission frame.

[0011] Furthermore, a channel for the lifting plate to turn over is reserved between the partition baffle and the transmission belt. When the lifting plate turns over to the side close to the paddle board, the plate surface of the lifting plate is inclined upward.

[0012] Furthermore, the driving component includes: a machine shell, which is arranged in the middle above the packing orifice plate. A first driving shaft is arranged inside the machine shell. A spiral gear disk is arranged at the top end of the first driving shaft. From the outside to the inside in sequence at the bottom end of the first driving shaft, there are a first bevel gear disk and a second bevel gear disk; a second driving shaft, which penetrates through the transmission roller and is arranged at the top end of the machine shell. A spiral gear meshing with the spiral gear disk is arranged at one end of the second driving shaft; a third driving shaft, which is arranged at the bottom end of the machine shell. One end of the third driving shaft is connected to the rotating shell, and a first bevel gear meshing with the first bevel gear disk is arranged at the other end of the third driving shaft; a fourth driving shaft, which penetrates through the third driving shaft and extends to the inside of the rotating shell. A driving end for driving the rotating seat to rotate intermittently is arranged along the axial direction of the fourth driving shaft. A second bevel gear meshing with the second bevel gear disk is arranged at one end of the fourth driving shaft.

[0013] Furthermore, the gear transmission ratio of the first bevel gear disk to the first bevel gear is greater than the gear transmission ratio of the second bevel gear to the second bevel gear disk.

[0014] Furthermore, the driving end includes: a transmission gear plate, which is arranged on one side of the rotating seat; a second bracket, which is arranged inside the rotating shell away from the first bracket, and one side of the second bracket is provided with at least one group of transmission gears that are meshed with the transmission gear plate; a fan gear, which is arranged in the axial direction of the fourth driving shaft, and the fan gear is intermittently meshed with the transmission gear.

[0015] Furthermore, it also includes an inspection end cover, which is arranged on the spray tower and is staggered between the rotating shell and the transmission belt, and the inspection end cover is arranged flush with the filler orifice plate.

[0016] Furthermore, it also includes a spray ring tube arranged above the filter filler, the spray ring tube is provided in at least one group, the spray ring tube is supported and mounted on the spray tower, the spray ring tube is provided with at least one group of atomizing nozzles along its circumference, and the spray ring tube is connected to the external water supply equipment through a water supply pipe.

[0017] On the other hand, the present invention also provides a method for treating waste gas from a color-coated plate, comprising a waste gas treatment stage and a cleaning stage, wherein the waste gas treatment stage comprises the following steps: Step 1: the color coating waste gas is passed into the spray tower from bottom to top, and is filtered by the filter filler through the filler hole plate; Step 2: The atomizing nozzle sprays a water mist curtain above the filter filler, and atomizes, adsorbs and settles the filtered color coating waste gas, and exhausts the waste gas after adsorption and settlement; The cleanup phase includes the following steps: Step 1: After the single spraying and impurity removal of the color-coated waste gas is completed, the paddle is controlled to flip and retract, and the filter filler that slides and accumulates on the bottom of the filler hole plate slope is moved and vibrated, so that the paint mist impurities intercepted and filtered between the pores inside the filter filler and the residual water mist entrained with impurities are vibrated and separated, and the high-efficiency filtering and interception characteristics of the filter filler pores are maintained, and the filter filler after vibration impurity removal is moved to one side of the transmission belt; Step 2: Control the transmission belt to drive the lifting plate to flip and transmit, and circulate and lift the filter filler after vibration and impurity removal at the bottom of the filler hole plate, and flip the material to the top of the other side to keep the filter filler evenly mixed up and down, so as to reduce the accumulation of internal impurities in the bottom filter filler due to the initial filtration and interception of too much color-coated waste gas, which cannot be completely removed, resulting in a slow circulation rate of subsequent color-coated waste gas.

[0018] The present invention has the following beneficial effects: (1) After the single - time spraying of the color - coated waste gas by the color - coated board waste gas treatment device, driven by the driving component, on the one hand, it drives the rotation of the combination of the rotating shell and the paddle board and drives the paddle board to expand and contract and vibrate relative to the rotating shell. While stirring the filter packing at the bottom, it simultaneously applies a vibration force, circulates and stirs the filter packing, and vibrates and removes the filtered impurities and the residual water mist carrying impurities inside it, so that the filter packing always maintains high - efficiency filtering and interception characteristics and extends its service life. On the other hand, it drives the rotation of the combination of the transmission belt and the lifting plate, and cyclically flips and pushes up the filter packing after stirring and vibrating, so that the accumulated filter packing always slides down to the bottom for vibration impurity removal, ensuring the comprehensiveness of impurity removal inside the filter packing.

[0019] (2) The color - coated board waste gas treatment device, through the combined rotation, expansion, and contraction vibration of the rotating shell and the paddle board, enables the rotating shell to drive the paddle board to cyclically stir and drive the filter packing, stir the filter packing between the paddle boards, and utilize the synchronous expansion, contraction, and vibration of the paddle board itself to transmit the vibration to the filter packing, and vibrate and remove the filtered and adhered impurities and the residual water mist carrying impurities inside the filter packing, so that various impurities are separated from the inside of the filter packing to ensure the persistent filtering and interception characteristics of the filter packing.

[0020] (3) The color - coated board waste gas treatment device, through the transmission combination of the transmission belt and the lifting plate, on the one hand, can make the filter packing after vibration impurity removal be transported away from the paddle board, so that the filter packing cyclically slides between the paddle boards for vibration impurity removal. On the other hand, it can make the filter packing be turned over and mixed from bottom to top, so that the filter packing is mixed up and down, reducing the situation that the subsequent waste gas flow rate is slow due to excessive initial filtering and interception of color - coated waste gas at the bottom of the filter packing, and improving the uniform flow - through filtering and interception characteristics of the color - coated waste gas.

[0021] (4) The color - coated board waste gas treatment device, through the cyclic transportation of the filter packing by the transmission combination of the transmission belt and the lifting plate, makes the filter packing be cyclically transported to the other side for mixing. When the filter packing needs to be regularly cleaned subsequently, only need to open the maintenance end - cover, and utilize the cyclic transportation characteristics of the filter packing, so that while the filter packing is being cyclically transported, it is finally discharged through the maintenance end - cover, without the need to disassemble and assemble the spray tower as a whole, reducing the daily maintenance intensity.

[0022] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above - mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "perimeter", etc. indicating orientation or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0027] Please refer to Figures 1-18 , the embodiments of the present invention provide a technical solution: a color-coated board waste gas treatment device and a treatment method, On the one hand, the present invention provides a color-coated board waste gas treatment device.

[0028] Please refer to Figures 1-2 , Figure 18, The color-coated board waste gas treatment device includes a spray tower 1, a packing orifice plate 71 built inside the spray tower 1. The packing orifice plate 71 is provided with not less than one group, and the packing orifice plate 71 is provided with not less than one group of inclined surfaces 74 along its circumferential direction. A partition baffle 73 is provided at the top of the inclined surface 74, and filter packing 8 is stacked on the slope of the inclined surface 74. The packing bottom plate 7 composed of the packing orifice plate 71, the central platform 72, the partition baffle 73, and the inclined surface 74 is used as the stacking platform for the filter packing 8. Among them, on the one hand, the packing orifice plate 71 serves as the flow channel for the color-coated waste gas, enabling the waste gas to flow through the packing orifice plate 71 into the inside of the filter packing 8 for filtration and interception. On the other hand, it serves as a support plate to stack and support the filter packing 8. The central platform 72 provided in the middle of the packing orifice plate 71 serves as the support platform for the casing 10, enabling the transmission of its internal components. And by setting the inclined surface 74 on the packing orifice plate 71, the stacked filter packing 8 tends to flow towards the bottom of the inclined surface 74, so as to contact the paddle 12 of the rotating shell 11 more comprehensively, perform material feeding and vibration impurity removal, and cyclically push the filter packing 8 after vibration impurity removal towards the conveyor belt 13. At the same time, by setting the partition baffle 73 at the top of the inclined surface 74, under the separation of the conveyor belt 13, the filter packing 8 is successively separated into independent parts, and the filter packing 8 can be successively conveyed to adjacent parts under the transmission combination of the conveyor belt 13 and the lifting plate 14, and the filter packing 8 at the bottom side is cyclically turned over and conveyed to the upper part on the other side. On the one hand, the filter packing 8 after vibration impurity removal is conveyed away. On the other hand, the filter packing 8 is turned over and mixed up and down, avoiding that the filter packing 8 at the bottom has too many internal impurities due to contacting too much color-coated waste gas, affecting the subsequent flow rate of the color-coated waste gas, making the filter packing 8 evenly mixed up and down, always maintaining a high and uniform flow rate, and filtering and intercepting the impurities in the color-coated waste gas. Specifically.

[0029] A rotating shell 11 is provided at the bottom of the inclined surface 74. The rotating shell 11 is provided with not less than one group of paddle 12 along its circumferential direction. By setting the combination of the rotating shell 11 and the paddle 12 at the bottom of the inclined surface 74, using the rotational drive of the rotating shell 11 and the paddle 12, the filter packing 8 at the bottom of the inclined surface 74 is pushed by material feeding. While pushing away the filter packing 8 at the bottom part, the filter packing 8 in the remaining parts slides and accumulates towards the bottom part of the inclined surface 74 under the action of gravity, so as to continuously push the filter packing 8 in the local area by material feeding, and using the continuous elastic expansion and contraction of the paddle 12 relative to the rotating shell 11, a telescopic vibration state is formed to perform synchronous vibration work on the filter packing 8 during material feeding and pushing, so as to vibrate and remove the impurities filtered and intercepted in the filter packing 8 and the water mist carrying the impurities, so as to ensure the efficient and continuous filtration and interception work of the impurities in the subsequent color-coated waste gas.

[0030] Furthermore, a transmission belt 13 is provided on one side of the rotating shell 11 near the dividing baffle 73, and at least one group of lifting plates 14 are provided along the belt surface of the transmission belt 13. The transmission belt 13 pushes the lifting plates 14 cyclically, and the filter filler 8 after vibration stripping is cyclically transferred to the lifting plates 14 at the bottom. The filter filler 8 after vibration and impurity removal at the bottom is lifted, flipped and broadcast to the other side of the top by the transmission of the lifting plates 14. On the one hand, the filter filler 8 at the bottom of the slope 74 is continuously fed, and on the other hand, the filter filler 8 is cyclically flipped up and down.

[0031] In addition, a driving component is provided in the upper middle part of the filler hole plate 71, which is used to drive the rotating shell 11 and the transmission belt 13 to rotate, so that the paddle plate 12 on the rotating shell 11 rotates and reciprocates, applies vibration to the filter filler 8 at the bottom of the inclined surface 74 and transfers the filter filler 8 to the lifting plate 14 of the transmission belt 13. The transmission belt 13 drives the lifting plate 14 to turn the bottom filter filler 8 to the top of the other side. By utilizing the drive of the driving component, the paddle plate 12 and the lifting plate 14 are integrally linked. While vibrating and removing impurities from the filter filler 8, it also has the function of turning the filter filler 8 up and down, so that the filter filler 8 can remove impurities and maintain a uniform mixed state, so as to maintain efficient filtering and interception of impurities in the color-coated exhaust gas in the subsequent process.

[0032] See also Figures 4-6 , Figures 8-18 In order to realize the material pushing and vibration removal of the filter filler 8, the driving assembly includes a casing 10 arranged in the middle of the upper part of the filler orifice plate 71, and a first driving shaft 16 is arranged inside the casing 10. The bottom end of the first driving shaft 16 is provided with a bevel gear plate 20 and a bevel gear plate 21 from the outside to the inside, and includes a third driving shaft 26 arranged at the bottom end of the casing 10, one end of the third driving shaft 26 is connected to the rotating shell 11, and the other end of the third driving shaft 26 is provided with a bevel gear 22 meshing with the bevel gear plate 20. The first driving shaft 16 is driven to rotate by the driving motor 15 arranged on the casing 10, and then the bevel gear plate 20 is driven to rotate. The meshing transmission of the bevel gear plate 20 and the bevel gear plate 21 is used to drive the third driving shaft 26 to rotate, and the rotating shell 11 and its paddle 12 are driven to rotate in conjunction, so as to continuously push the filter filler 8 at the bottom of the slope of the inclined surface 74, and continuously push the filter filler to the side close to the transmission belt 13.

[0033] As a further solution of this embodiment, the drive assembly further includes a fourth drive shaft 27 that extends through the third drive shaft 26 into the interior of the rotating housing 11. The fourth drive shaft 27 is provided with a drive end along its axial direction for driving the rotating seat 33 to rotate intermittently. One end of the fourth drive shaft 27 is provided with a second bevel gear 23 that meshes with the second bevel gear disk 21. Among them, the drive end includes a transmission gear disk 36 provided on one side of the rotating seat 33, a second support 29 provided inside the rotating housing 11 away from the first support 28, at least one set of transmission gears 38 provided on one side of the second support 29 and meshing with the transmission gear disk 36, and a sector gear 39 provided along the axial direction of the fourth drive shaft 27. The sector gear 39 is intermittently meshed with the transmission gear 38. While the drive motor 15 drives the first drive shaft 16 to rotate, it drives the second bevel gear disk 21 to rotate synchronously. By using the meshing transmission between the second bevel gear disk 21 and the second bevel gear 23, it drives the fourth drive shaft 27 to rotate, and then drives the sector gear 39 to rotate. At this time, although the meshing combination of the transmission gear 38 and the transmission gear disk 36 rotates synchronously with the rotation of the paddle 12, when the sector gear 39 rotates to mesh with the transmission gear 38, it still maintains the meshing transmission with the transmission gear 38, pushing the transmission gear disk 36 to rotate intermittently, generating an intermittent thrust, and pushing the rotating seat 33 to rotate intermittently.

[0034] Furthermore, Figures 10-18 , a first support 28 is provided inside the rotating housing 11. A rotating shaft 34 is provided in the middle of the first support 28. There is a clockwork spring 35 between the first support 28 and the rotating shaft 34. One end of the rotating shaft 34 is provided with a rotating seat 33. The rotating seat 33 is provided with not less than one set of arm force push rods 32 along its circumferential direction. The arm force push rods 32 are connected to the paddle 12 and drive the paddle 12 to expand and contract and vibrate. While the rotating seat 33 rotates intermittently, on the one hand, it drives the arm force push rods 32 to rotate synchronously, and uses the rotational thrust of the arm force push rods 32 to push the paddle 12 out of the rotating housing 11. On the other hand, it drives the clockwork spring 35 on the rotating shaft 34 to wind up. Then, after the intermittent rotational thrust of the rotating seat 33 disappears, the clockwork spring 35 resets, generating a reset thrust, causing the rotating seat 33 to rotate and reset, driving the paddle 12 to retract into the rotating housing 11 by inertia. Then, by using the reciprocating expansion and contraction of the paddle 12, an expansion and contraction vibration thrust is generated to vibrate the filter packing 8 between the paddles 12 to vibrate and separate the impurities inside the filter packing 8.

[0035] In addition, the gear transmission ratio between the first bevel gear disk 20 and the first bevel gear 22 is greater than that between the second bevel gear 23 and the second bevel gear disk 21. According to the principle that the greater the gear transmission ratio, the slower the rotational speed, the gear transmission ratio between the first bevel gear disk 20 and the first bevel gear 22 is larger. Therefore, the rotational speed of the third drive shaft 26 driving the rotating shell 11 is slower, and the rotational speeds of the internal transmission gear 38 and the transmission gear disk 36 are slower. While the gear transmission ratio between the second bevel gear 23 and the second bevel gear disk 21 is smaller, so the rotational speed of the fourth drive shaft 27 relative to the rotating shell 11 is faster. The sector gear 39 on its shaft can overcome the self-rotational speed of the transmission gear 38 and the transmission gear disk 36, and intermittently engage and drive with them to generate an intermittent driving force in the active form.

[0036] It should be noted that by providing the gasket strip 31 on the rotating shell 11 to seal and guide the expansion and contraction of the paddle 12, when the paddle 12 expands and contracts and vibrates, it isolates the external air and water mist, so as to reduce the situation of water mist air entering the rotating shell 11. And by providing the anti-slip boss 30 at the tail end of the paddle 12, it can prevent the paddle 12 from slipping out of the rotating shell 11 when expanding and contracting and vibrating.

[0037] Please refer to Figures 4-7 , to achieve the up-and-down flipping of the filter packing 8, the drive assembly further includes a spiral gear disk 17 provided at the top end of the first drive shaft 16. A transmission frame 24 is provided inside the transmission belt 13. Transmission rollers 25 for tensioning and driving the rotation of the transmission belt 13 are provided at both ends of the transmission frame 24. A second drive shaft 19 passing through the transmission roller 25 is provided at the top end of the machine shell 10. A spiral gear 18 meshing with the spiral gear disk 17 is provided at one end of the second drive shaft 19. While the drive motor 15 drives the first drive shaft 16 to rotate, it drives the spiral gear disk 17 to rotate synchronously. Using the meshing transmission between the spiral gear disk 17 and the spiral gear 18, it pushes the second drive shaft 19 to rotate, and then drives the transmission roller 25 to drive the transmission belt 13 to rotate, so that the lifting plate 14 circulates and flips along with the transmission of the transmission belt 13. When it flips to the side close to the paddle 12, it aggregates and lifts the filter packing 8 after material feeding and vibration impurity removal, and dials and flips the filter packing 8 at the bottom side to the top of the other side, so that while the filter packing 8 keeps circulating and falling for vibration impurity removal, it also has up-and-down flipping and mixing, in order to avoid continuous accumulation of the filter packing 8 at the bottom and excessive adhesion of internal impurities, which affects the subsequent circulation and spraying efficiency of the colored coating waste gas.

[0038] The lifting plate 14 is tilted upwards to move the filter packing 8 to the adjacent parts, and the lifting plate 14 is tilted upwards to move the filter packing 8 to the adjacent parts.

[0039] Also, see Figures 1-2 In order to realize the regular unloading, cleaning or replacement of the filter packing 8, an inspection end cover 6 is provided on the spray tower 1. The inspection end cover 6 is arranged on the spray tower, and the rotating shell 11 and the transmission belt 13 are staggered, and the inspection end cover 6 is arranged flush with the packing hole plate 71. When the filter packing 8 needs to be replaced or cleaned in the later stage, it is only necessary to open the inspection end cover 6. At this time, the filter packing 8 is cyclically turned over and conveyed by the combination of the transmission belt 13 and the lifting plate 14, so that the filter packing 8 is gradually turned over and conveyed to the area close to the side of the inspection end cover 6. When the filter packing 8 is turned over to the area close to the inspection end cover 6, the filter packing 8 is circulated and self-unloaded and discharged from the inspection end cover 6 for cleaning or replacement. There is no need to disassemble the spray tower 1 as a whole, which is more convenient and efficient for the daily filtering, replacement and cleaning of the filter packing 8.

[0040] In addition to the above, it further includes an air inlet 2 provided at the bottom of the tower body of the spray tower 1, an exhaust port 3 provided at the top of the spray tower 1, a sewage discharge port 5 provided at the bottom of the spray tower 1, and a spray header pipe 92 provided above the filter packing 8. The spray header pipe 92 is provided with not less than one group. The spray header pipe 92 is provided on the spray tower 1 through a support frame 91. The spray header pipe 92 is provided with not less than one group of atomizing nozzles 93 along its circumferential direction. The spray header pipe 92 is connected to an external water supply device through a supply water pipe 4. When spray-treating the color-coated waste gas, the color-coated waste gas is transported into the spray tower 1 through the air inlet 2, so that the color-coated waste gas is transported and circulated in a flowing manner from bottom to top. During the circulation process, the paint mist, impurities, etc. in the color-coated waste gas are filtered and intercepted by the filter packing 8. And by the pumping of the external water supply device, clean water is transported into the spray assembly composed of the support frame 91, the spray header pipe 92, and the atomizing nozzles 93 through the supply water pipe 4. The clean water is atomized and sprayed out through the atomizing nozzles 93 to form a uniform water mist surface, which combines with the flowing color-coated waste gas, adsorbs and settles the impurities in the waste gas, and makes the water mist disperse into the filter packing 8 to further enhance the combined adsorption efficiency of the impurities in the color-coated waste gas. Then, the waste gas after spray impurity removal is discharged through the exhaust port 3 for the next step of treatment, and the sewage generated by spraying is finally discharged through the sewage discharge port 5.

[0041] On the other hand, the present invention further provides a method for treating color-coated board waste gas, including a waste gas treatment stage and a cleaning stage. The waste gas treatment stage includes the following steps: Step 1, the color-coated waste gas is introduced into the spray tower 1 from bottom to top and filtered by the filter packing 8 through the packing orifice plate 71; Step 2, the atomizing nozzles 93 spray a water mist curtain above the filter packing 8, and atomize, adsorb, and settle the filtered color-coated waste gas. The waste gas after adsorption and settlement is exhausted; The cleaning stage includes the following steps: Step 1, after the single-time spray impurity removal of the color-coated waste gas is completed, control the paddle 12 to flip and extend, stir the filter packing 8 that has slipped and accumulated at the bottom of the slope of the packing orifice plate 71 and apply vibration, so that the paint mist impurities intercepted and filtered between the internal pores of the filter packing 8 and the residual water mist carrying the impurities are vibrated and separated, maintaining the efficient filtering and intercepting characteristics of the pores of the filter packing 8, and stirring the filter packing 8 after vibration impurity removal to one side of the conveyor belt 13; Step 2, control the conveyor belt 13 to drive the lifting plate 14 to flip and drive, and circularly lift and transport the filter packing 8 after vibration impurity removal at the bottom of the packing orifice plate 71, and turn it over to the top on the other side, so that the filter packing 8 is evenly mixed up and down, reducing the situation that excessive internal impurities accumulate at the bottom of the filter packing 8 due to excessive initial filtering and interception of the color-coated waste gas, resulting in a slow subsequent circulation rate of the color-coated waste gas that cannot be completely removed.
