Description

Technical Field

[0001] This invention relates to the field of organic waste gas treatment technology in painting workshops, and more specifically, to an organic waste gas adsorption device for painting workshops with self-cleaning function. Background Technology

[0002] Painting is a critical process in the automotive manufacturing industry, requiring a high level of cleanliness during on-site application. However, the painting process generates exhaust pollutants, and these pollutants accumulate and form impurities that fall onto the paint film on the car body, creating visible defects that severely affect the quality of the paint coating on the car body surface.

[0003] Due to the influence of paint and processes, painting workshops can generate a large amount of toxic and harmful organic gases in a closed environment. If substances such as benzene and ammonia are inhaled by the human body, they can cause respiratory diseases such as choking and chest pain in mild cases, and damage the human nervous system and hematopoietic tissue in severe cases.

[0004] The organic waste gas from painting consists of two types of gases: soluble and insoluble. If the different physicochemical properties of these two types of gases can be utilized to treat them simultaneously, the adsorption efficiency of the organic waste gas can be effectively improved.

[0005] Zeolite can effectively adsorb organic waste gas, but there is a problem that the accumulation of deposits on its surface due to long-term adsorption can cause blockage of tiny pores. If not treated in time, it will reduce the adsorption efficiency or even cause the zeolite to be scrapped, greatly increasing the operation and maintenance costs.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0007] To address the problems in related technologies, this invention proposes an organic waste gas adsorption device for painting workshops with self-cleaning function, in order to overcome the aforementioned technical problems existing in the existing related technologies.

[0008] Therefore, the specific technical solution adopted by the present invention is as follows:

[0009] A self-cleaning organic waste gas adsorption device for a painting workshop includes a water storage tank. A water inlet pipe is installed at the front end of the water storage tank, and a water pump is installed at the top of the water storage tank. A water pump is installed at the top of a water inlet pipe. A water curtain cabinet is installed on one side of the water storage tank, with an operation panel located in the middle of one side. The top of the water inlet pipe connects to the interior of the water curtain cabinet. A drying pipe, containing a desiccant, is connected to an adsorption cabinet at the top of one side of the water curtain cabinet. A heat storage tank and water pump are installed at the bottom of one end of the water storage tank. An extraction box is installed at the bottom of the other side of the adsorption cabinet, with an extraction pipe at one end of the extraction box and a through-hole at one end of the extraction pipe. The adsorption cabinet has a rotary joint on its side wall, and an extraction pipe is installed on one side of the extraction box, penetrating the side wall of the adsorption cabinet. A heat storage cabinet is installed at one end of the adsorption cabinet, and the heat storage cabinet and the water pump in the heat storage cabinet's water tank are connected by a water storage tank connecting pipe. A water curtain cabinet adsorption cabinet connecting water pump is installed at the bottom of one side of the adsorption cabinet, and the water curtain cabinet adsorption cabinet connecting water pump is connected to the bottom of the water curtain cabinet through a water curtain cabinet adsorption cabinet connecting pipe. An adsorption cabinet heat storage cabinet connecting water pump is installed in the middle of one side of the heat storage cabinet, and the adsorption cabinet heat storage cabinet connecting water pump is connected to the adsorption cabinet through an adsorption cabinet heat storage cabinet connecting pipe. A drainage water pump is installed at the bottom of one side of the heat storage cabinet, and a drainage pipe is installed on one side of the drainage water pump.

[0010] Furthermore, to achieve preliminary treatment of organic waste gas, organic solvents can be introduced into the interior of the water curtain cabinet to effectively absorb suspended micro-impurities and soluble organic waste gas in the workshop. The sheet metal plates in the water curtain cabinet can generate more water curtains, increasing the organic solvent adsorption rate. A front water tank is set at the top of the interior of the water curtain cabinet, and a front diversion plate is set on one side of the front water tank. A front sheet metal plate is set at the top of the interior of the water curtain cabinet and on one side of the front water tank. The upper part of the front sheet metal plate forms a 45-degree angle with the top of the interior of the water curtain cabinet. The lower part of the front sheet metal plate is parallel to the top of the front diversion plate. The upper part of the front diversion plate is a vertical device, and the lower part of the front diversion plate is an arc-shaped bend. A rear water tank is set on the other side of the front water tank, and a rear sheet metal plate is set on one side of the rear water tank. A rear diversion plate is set at the bottom of the rear water tank, and the rear diversion plate is composed of five arc-shaped bend sheet metal plates.

[0011] Furthermore, to achieve secondary treatment of insoluble organic waste gas, zeolite sheets in the zeolite drum adsorb the insoluble organic waste gas. The air baffle, zeolite drum, and spiral brush are interconnected via gears, requiring only a single power source—a drive motor—to operate the device, reducing energy consumption and maintenance costs. Simultaneously, the horizontal structure design of the zeolite drum ensures constant contact with the spiral brush, achieving full-coverage cleaning of the zeolite sheet surface solely through the rotation of the zeolite drum and spiral brush. This solves the problem of clogging in the small pores of the zeolite sheets, further reducing maintenance costs. A heat flow channel is provided between the adsorption cabinet and the heat storage cabinet. A drive motor is located on the top of one side of the adsorption cabinet, with its output shaft passing through the side wall of the adsorption cabinet and connected to an air baffle. A front cover is located in the middle of one side of the adsorption cabinet. A rear end cover is located in the middle of one side, and an adsorption fan is located on one side of the front end cover. Rotating rings are located on adjacent side walls of the front and rear end covers, and zeolite rollers are installed inside the rotating rings. Slide tracks are provided on the inner wall of the rotating rings and on the outer walls of both ends of the zeolite rollers, with several bearings installed between the slide tracks. An air baffle is located inside the adsorption cabinet at the bottom of the zeolite roller. A transmission gear is located on one side wall of the adsorption cabinet, and a rotating shaft is connected to one side of the transmission gear via a transmission belt. One end of the rotating shaft passes through the side wall of the adsorption cabinet, and the other end is connected to a rotary joint. The zeolite roller is cylindrical, and several grooves are provided on its outer side, with zeolite flakes installed. The outer side of the zeolite roller fits tightly against the outer side of the air baffle. Linkage gears are located on the outer ends of both the zeolite roller and the air baffle, and they mesh with each other.

[0012] Furthermore, to transfer the heat source to the surface of the zeolite drum, the organic deposits accumulated on the zeolite sheet surface can be desorbed by increasing the temperature of the zeolite sheet, enabling the reuse of the zeolite sheet and improving resource utilization. Simultaneously, the hot air blown out through the exhaust channel not only heats the zeolite sheet but also further removes impurities from its surface. These impurities are then sucked away through intake channels one and two, maintaining the effective operation of the zeolite drum. The heat flow channel includes a square... The frame has a square frame with a guide plate at the bottom and an arc-shaped structure at the bottom. An arc-shaped baffle is located at the bottom inside the guide plate, and an arc-shaped baffle is located below the first arc-shaped baffle. An air outlet channel is formed between the first arc-shaped baffle and the second arc-shaped baffle. Several channel connecting pipes are installed through the first arc-shaped baffle and the second arc-shaped baffle. An air intake channel is formed between the first arc-shaped baffle and the inner wall of the guide plate, and an air intake channel is formed between the second arc-shaped baffle and the inner wall of the guide plate. Several connecting holes are provided at the bottom of the guide plate.

[0013] Furthermore, in order to achieve the connection between the second extraction pipe and the guide plate, several gas delivery pipes that match the connection holes are provided on the outside of the second extraction pipe and inside the adsorption cabinet.

[0014] Furthermore, in order to ensure that some impurities are sucked into the air extraction port when the spiral brush cleans the surface of the zeolite roller, thus removing the accumulated substances and impurities on the zeolite sheets, the zeolite roller's efficiency is not affected by the accumulation of impurities during the cleaning process. Through double impurity removal, the adsorption performance of the zeolite sheets is repeatedly guaranteed. An air extraction port is opened on the side wall of the rotating shaft near the rotary joint, and the air extraction port is matched with the air extraction pipe. A spiral brush that matches the zeolite roller is set on the outside of the rotating shaft, and several evenly arranged air extraction holes are opened on the outside of the rotating shaft.

[0015] Furthermore, to generate heat, impurities mixed in the organic solvent can be filtered out through a filter screen and dried by the heat generated by the heating tubes above. The impurity removal drawer can be removed for cleaning, making full use of the heat generated by the device. The organic solvent flows into the water storage tank for the next cycle of use, realizing the recovery of organic solvent. The pipes and water pumps in the device can control the recycling and discharge of organic solvent, optimizing resource utilization. Several heating tubes are installed at the top of the heat storage cabinet. A heating fan is installed on the side of the heat storage cabinet away from the heat flow channel, and the heating fan and heating tubes are at the same height. An impurity removal drawer is installed in the middle of the heat storage cabinet and at the bottom of the connecting pipe between the adsorption cabinet and the heat storage cabinet. A filter screen is installed at the bottom of the impurity removal drawer.

[0016] Furthermore, in order to deliver the organic solvent to the front and rear water tanks, two sets of outlet pipes are installed at the top of the water supply pipes, which extend into the interior of the front and rear water tanks respectively.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention combines the adsorption effects of a water curtain cabinet and a zeolite roller, which can effectively treat organic waste gas generated in the painting workshop. The water curtain cabinet absorbs suspended micro-impurities and soluble organic waste gas through water curtain and organic solvent, while the zeolite roller is specifically used to adsorb insoluble organic waste gas, thereby achieving a more comprehensive purification effect.

[0019] 2. By setting up a front diversion plate and a front sheet metal plate, the initial treatment of organic waste gas is achieved. By introducing organic solvents into the water curtain cabinet, the small impurities suspended in the workshop and soluble organic waste gas can be effectively absorbed. The sheet metal plate in the water curtain cabinet can generate more water curtains, increasing the adsorption rate of organic solvents.

[0020] 3. By setting up an adsorption cabinet and a zeolite drum, secondary treatment of insoluble organic waste gas is achieved. The zeolite sheets in the zeolite drum adsorb the insoluble organic waste gas, and the wind baffle, zeolite drum, and spiral brush are interconnected by gears. Only one power source, the drive motor, is needed to operate the device, reducing energy consumption and maintenance costs. At the same time, the horizontal structure design of the zeolite drum can maintain constant contact with the spiral brush. The rotation of the zeolite drum and spiral brush is sufficient to achieve full coverage cleaning of the zeolite sheet surface, solving the problem of clogging of the small pores of the zeolite sheet and reducing maintenance costs.

[0021] 4. By setting up a heat flow channel, the heat source can be delivered to the surface of the zeolite drum. By increasing the temperature of the zeolite sheets, the organic deposits accumulated on the surface of the zeolite sheets can be desorbed, realizing the reuse of zeolite sheets and improving resource utilization. At the same time, the hot air blown out through the air outlet channel not only heats the zeolite sheets, but also further removes impurities from the surface of the zeolite sheets. Then, the blown-off impurities are sucked away through air intake channel one and air intake channel two, maintaining the effective operation of the zeolite drum.

[0022] 5. By setting a rotating shaft and spiral brush, some impurities are sucked into the air extraction port when the spiral brush cleans the surface of the zeolite drum. This removes the accumulated substances and impurities on the zeolite sheets, ensuring that the zeolite drum's efficiency is not affected by the accumulation of impurities during the cleaning process. Through double impurity removal, the adsorption performance of the zeolite sheets is repeatedly guaranteed.

[0023] 6. By setting up a heat storage cabinet, heating tubes, and a cleaning drawer, heat is generated. At the same time, impurities mixed in the organic solvent can be filtered out through the filter screen and dried by the heat generated by the heating tubes above. The cleaning drawer can be removed for cleaning. The heat generated by the device is fully utilized. The organic solvent flows into the water storage tank for the next cycle of use, realizing the recovery of organic solvent. The pipes and water pumps in the device can control the recycling and discharge of organic solvent, optimizing resource utilization. Attached Figure Description

The top of one side of the water curtain cabinet 6 is connected to an adsorption cabinet 15 through a drying pipe 13, and a desiccant 14 is provided inside the drying pipe 13.

Outside the exhaust pipe 47, and inside the adsorption cabinet 15, there are several air supply pipes 4701 that cooperate with the connection hole 3309.

[0042] By utilizing the above-mentioned technical solution of the present invention, the present invention combines the adsorption effects of the water curtain cabinet 6 and the zeolite roller 25, which can effectively treat the organic waste gas generated in the painting workshop. The water curtain cabinet absorbs suspended micro-impurities and soluble organic waste gas through water curtain and organic solvent, while the zeolite roller is specifically used to adsorb insoluble organic waste gas, thereby achieving a more comprehensive purification effect.

[0043] In one embodiment, for the aforementioned water curtain cabinet 6, a front water tank 9 is provided at the top interior of the water curtain cabinet 6, a front diversion plate 7 is provided on one side of the front water tank 9, and a front sheet metal plate 8 is provided at the top interior of the water curtain cabinet 6 and on one side of the front water tank 9. Furthermore, it should be noted that the front diversion plate 7 and the front sheet metal plate 8 are fixedly connected, and the organic solvent in the front water tank 9 flows down through the gap between the front water tank 9 and the front diversion plate 7. The upper end of the front sheet metal plate 8 forms a 45-degree angle with the top interior of the water curtain cabinet 6, and the lower end of the front sheet metal plate 8 is parallel to the top of the front diversion plate 7. The upper end of the front diversion plate 7 is a vertical device, and the lower end of the front diversion plate 7 is an arc-shaped curved device. The other side of the front water tank 9... A rear water tank 10 is provided on one side, and a rear sheet metal plate 11 is provided on one side of the rear water tank 10. A rear diversion plate 12 is provided at the bottom of the rear water tank 10, and the rear diversion plate 12 is composed of five curved sheet metal plates (it should be noted that the five curved sheet metal plates are arranged opposite each other, with three plates on one side and two plates on the other side). By setting the front diversion plate 7 and the front sheet metal plate 8, the preliminary treatment of organic waste gas is achieved. The organic solvent introduced into the water curtain cabinet 6 can effectively absorb the small impurities suspended in the workshop and the soluble organic waste gas. The sheet metal plate in the water curtain cabinet 6 can generate more water curtain, which increases the adsorption rate of organic solvent.

[0044] In one embodiment, for the adsorption cabinet 15, a heat flow channel 33 is provided between the adsorption cabinet 15 and the heat storage cabinet 30. A drive motor 16 is provided on the top of one side of the adsorption cabinet 15. The output shaft of the drive motor 16 passes through the side wall of the adsorption cabinet 15 and is provided with a wind baffle 17. A front cover 20 is provided in the middle of one side of the adsorption cabinet 15, and a rear cover 21 is provided in the middle of the other side of the adsorption cabinet 15. An adsorption fan 22 is provided on one side of the front cover 20. A rotating ring 28 is provided on the adjacent side walls of the front cover 20 and the rear cover 21. A zeolite roller 25 is provided inside the rotating ring 28. Slides are provided on the inner wall of the rotating ring 28 and the outer walls of both ends of the zeolite roller 25. Several bearings 29 are provided between the slides. A wind baffle 27 is provided inside the adsorption cabinet 15 and at the bottom of the zeolite roller 25. A transmission gear 18 is provided on one side wall of the adsorption cabinet 15. A rotating shaft 23 is connected to one side of the transmission gear 18 through a transmission belt 19. One end of the rotating shaft 23 passes through the adsorption cabinet 15. The side wall of cabinet 15, the other end of rotating shaft 23 is connected to rotary joint 46; zeolite drum 25 is cylindrical, and several grooves are opened on the outer side of zeolite drum 25 and zeolite pieces 26 are provided. The outer side of zeolite drum 25 is closely fitted with the outer side of wind baffle 17. Both ends of zeolite drum 25 and wind baffle 17 are equipped with linkage gears that mesh with each other, thereby realizing secondary treatment of insoluble organic waste gas. Insoluble organic waste gas is adsorbed by zeolite pieces 26 in zeolite drum 25, and wind baffle 17, zeolite drum 25 and spiral brush 24 are linked by gears. Only one power source, drive motor 16, is needed to realize the operation of the device, reducing energy consumption and maintenance costs. At the same time, the horizontal structure design of zeolite drum 25 can keep in contact with spiral brush 24 at all times. Only the rotation of zeolite drum 25 and spiral brush 24 is needed to achieve full coverage cleaning of zeolite piece 26 surface, solving the problem of clogging of small pores of zeolite piece 26 and reducing maintenance costs.

[0045] In addition, it should be noted that the zeolite drum 25 and the air baffle 17 fit tightly after installation. The air baffle 17 and the air baffle 27 block the organic waste gas in the space on the left side of the adsorption cabinet 15, ensuring the overall airtightness of the device.

[0046] In one embodiment, the heat flow channel 33 includes a square frame 3301 disposed between the adsorption cabinet 15 and the heat storage cabinet 30. A guide plate 3302 is provided at the bottom of the square frame 3301 (it should be noted that the generated heat enters the interior of the square frame 3301 and then into the guide plate 3302 at the bottom of the square frame 3301). The bottom of the guide plate 3302 has an arc-shaped structure. An arc-shaped baffle 3303 is provided at the bottom of the guide plate 3302. An arc-shaped baffle 3304 is provided below the arc-shaped baffle 3303. An air outlet channel 3305 is provided between the arc-shaped baffle 3303 and the arc-shaped baffle 3304. Several channel connecting pipes 3306 are provided through the arc-shaped baffle 3303 and the arc-shaped baffle 3304. The inner wall of the arc-shaped baffle 3303 and the guide plate 3302 is configured as a suction channel 3307, and the inner wall of the arc-shaped baffle 3304 and the guide plate 3302 is configured as a suction channel 3308. The bottom end of the guide plate 3302 is provided with several connecting holes 3309, so that the heat source can be delivered to the surface of the zeolite drum 25. By increasing the temperature of the zeolite sheet 26, the organic deposits accumulated on the surface of the zeolite sheet 26 can be desorbed, realizing the reuse of the zeolite sheet 26 and improving the resource utilization rate. At the same time, the hot air blown out through the exhaust channel 3305 not only heats the zeolite sheet 26, but also further removes impurities from the surface of the zeolite sheet 26. Then, the blown-off impurities are sucked away through the suction channel 3307 and the suction channel 3308, maintaining the effective operation of the zeolite drum 25.

[0047] In one embodiment, for the aforementioned rotating shaft 23, an air extraction port 48 is provided on the side wall of the end of the rotating shaft 23 near the rotary joint 46, and the air extraction port 48 cooperates with the air extraction pipe 45. A spiral brush 24 that cooperates with the zeolite roller 25 is provided on the outer side of the rotating shaft 23, and a plurality of evenly arranged air extraction holes 49 are provided on the outer side of the rotating shaft 23. Thus, when the spiral brush 24 cleans the surface of the zeolite roller 25, some impurities will be sucked into the air extraction port 48, thereby removing the accumulated substances and impurities on the zeolite sheet 26. This ensures that the zeolite roller will not be affected by the accumulation of impurities during the cleaning process. Through double impurity removal, the adsorption performance of the zeolite sheet 26 is repeatedly guaranteed.

[0048] In addition, it should be noted that when the device is running, the spiral brush 24 can clean the organic deposits on the surface of the zeolite sheet 26 by rotating, so as to prevent the deep holes of the zeolite sheet 26 from becoming blocked. The swept-off organic deposits can fall into the adsorption cabinet 15 along the wind baffle 27.

[0049] In one embodiment, for the aforementioned heat storage cabinet 30, a plurality of heating tubes 31 are provided at the top of the heat storage cabinet 30, and a heating fan 32 is provided on the side of the heat storage cabinet 30 away from the heat flow channel 33, with the heating fan 32 and the heating tubes 31 at the same height. A cleaning drawer 34 is provided in the middle of the heat storage cabinet 30 and at the bottom of the adsorption cabinet heat storage cabinet connecting pipe 38. A filter screen 35 is provided at the bottom of the cleaning drawer 34, thereby generating heat. At the same time, impurities mixed in the organic solvent can be filtered out through the filter screen 35 and dried by the heat generated by the heating tubes 31 above. The cleaning drawer 34 can be removed for cleaning, making full use of the heat generated by the device. The organic solvent flows into the water storage tank 1 for the next round of use, realizing the recovery of organic solvent. The pipes and water pumps in the device can control the recycling and discharge of organic solvent, optimizing resource utilization.

[0050] In one embodiment, the water supply pipe 4 is provided with two sets of outlet pipes at its top end, which extend into the front water tank 9 and the rear water tank 10 respectively, so as to deliver organic solvents to the front water tank 9 and the rear water tank 10.

[0051] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0052] In practical applications, when using this adsorption device, the operator controls the start and stop of the device through the control panel 5. After the device is started, firstly, organic solvent is injected into the water storage tank 1 through the water inlet pipe 2. Then, the organic solvent in the water storage tank 1 is sent to the front water tank 9 and the rear water tank 10 through the water supply pipe 4 by the water pump 3. After being added to the designated position, it flows down along the front guide plate 7 and the rear guide plate 12 respectively, forming an organic solvent water curtain. Then, the adsorption fan 22 is started to draw the organic waste gas from the painting workshop into the device through the water curtain cabinet 6. After passing through the water curtain cabinet 6, the dust and soluble organic waste gas in the organic waste gas are absorbed by the organic solvent water curtain and fall into the water curtain cabinet 6 with the organic solvent, thus achieving the preliminary treatment of the organic waste gas.

[0053] After preliminary treatment, the organic waste gas is dried by desiccant 14 when passing through drying pipe 13, and then sent to adsorption cabinet 15. After passing through zeolite drum 25, the insoluble organic waste gas is adsorbed by zeolite sheets 26, and the purified air is discharged with adsorption fan 22.

[0054] Driven by the drive motor 16 and gears, the windbreak 17, zeolite roller 25, and rotating shaft 23 rotate in tandem. The spiral brush 24 covering the rotating shaft 23 cleans the organic deposits from the zeolite flakes 26 through a full-coverage rotation. Then, the extraction box 44 is activated, creating a vacuum that generates negative pressure inside the extraction pipe 47. The cleaned organic deposits from the zeolite flakes 26 then enter the extraction port 48 through the extraction hole 49, are extracted along the extraction pipe 47, and recovered. The contents are then stored in the heat storage cabinet 30. Heating tube 31 generates a high temperature of 180-200℃, which is blown to the surface of zeolite sheet 26 through hot flow channel 33 by heating fan 32. When zeolite sheet 26 rotates to the air outlet of hot flow channel 33, it is heated, thereby achieving the desorption of organic deposits. At the same time, due to the start of the suction box 44, a negative pressure is generated inside the second suction pipe 47 and the air supply pipe 4701. Then, under the action of connecting hole 3309 and channel connecting pipe 3306, a negative pressure is generated inside the first suction channel 3307 and the second suction channel 3308, which can suck away the impurities blown away by the hot air and maintain the effective operation of zeolite drum 25.

[0055] In addition, any impurities or organic deposits that are not removed will fall to the bottom of the adsorption cabinet 15. Then, the organic solvent in the water curtain cabinet 6 will be sent into the adsorption cabinet 15 through the water curtain cabinet adsorption cabinet connecting pipe 36, and then into the impurity removal drawer 34 in the heat storage cabinet 30 through the adsorption cabinet heat storage cabinet connecting pipe 38. After being filtered by the filter screen 35, the organic solvent that meets the purity standard can be recovered to the water storage tank 1 through the heat storage tank water storage tank connecting pipe 40. The organic solvent that does not meet the purity standard will be discharged from the drain pipe 42. At the same time, the high temperature generated inside the heat storage cabinet 30 is also used to dry the organic impurities on the filter screen 35. When a certain amount is accumulated, the impurity removal drawer 34 can be opened to clean it.

[0056] In summary, by utilizing the above-mentioned technical solution of this invention, the present invention combines the adsorption effects of the water curtain cabinet 6 and the zeolite roller 25, effectively treating the organic waste gas generated in the painting workshop. The water curtain cabinet absorbs suspended micro-impurities and soluble organic waste gas through the water curtain and organic solvent, while the zeolite roller is specifically used to adsorb insoluble organic waste gas, thereby achieving a more comprehensive purification effect. By setting the front guide plate 7 and the front sheet metal plate 8, preliminary treatment of organic waste gas is achieved. The organic solvent introduced into the interior of the water curtain cabinet 6 can effectively absorb suspended micro-impurities and soluble organic waste gas in the workshop, while the sheet metal plate in the water curtain cabinet 6 can generate more water curtain, increasing the organic solvent adsorption rate. By setting up the adsorption cabinet 15 and the zeolite drum 25, secondary treatment of insoluble organic waste gas is achieved. The insoluble organic waste gas is adsorbed by the zeolite sheets 26 in the zeolite drum 25. The wind baffle 17, the zeolite drum 25 and the spiral brush 24 are interconnected by gears. Only one power source, the drive motor 16, is needed to operate the device, reducing energy consumption and maintenance costs. At the same time, the horizontal structure design of the zeolite drum 25 can maintain constant contact with the spiral brush 24. The rotation of the zeolite drum 25 and the spiral brush 24 is sufficient to achieve full coverage cleaning of the surface of the zeolite sheets 26, solving the problem of clogging of the small pores of the zeolite sheets 26 and reducing maintenance costs. By setting up the heat flow channel 33, heat can be delivered to the surface of the zeolite drum 25. By increasing the temperature of the zeolite flakes, the organic deposits accumulated on the surface of the zeolite flakes 26 can be desorbed, enabling the reuse of the zeolite flakes 26 and improving resource utilization. At the same time, the hot air blown out through the air outlet channel 3305 not only heats up the zeolite flakes 26 but also further removes impurities from the surface of the zeolite flakes 26. Then, the blown-off impurities are sucked away through the first suction channel 3307 and the second suction channel 3308, maintaining the effective operation of the zeolite drum 25. By setting up the rotating shaft 23 and the spiral brush 24, some impurities are sucked into the air extraction port 48 when the spiral brush 24 cleans the surface of the zeolite drum 25, realizing the removal of accumulated substances and impurities on the zeolite flakes 26. This ensures that the zeolite drum's efficiency is not affected by the accumulation of impurities during the cleaning process. Through dual impurity removal, the adsorption performance of the zeolite flakes 26 is repeatedly guaranteed. By setting up a heat storage cabinet 30, a heating tube 31, and a cleaning drawer 34, heat is generated. At the same time, impurities mixed in the organic solvent can be filtered out by the filter screen 35 and dried by the heat generated by the heating tube 31 above. The cleaning drawer 34 can be removed for cleaning. The heat generated by the device is fully utilized. The organic solvent flows into the water storage tank 1 for the next round of use, realizing the recovery of organic solvent. The pipes and water pumps in the device can control the recycling and discharge of organic solvent, optimizing resource utilization.
