A support plate 4 is installed in the filter box 1 by bolt connection. The support plate 4 is located on the side of the filter layer 3 away from the air inlet 2. A runner 7 for accommodating zeolite is rotatably arranged on the support plate 4. The runner 7 is divided into a plurality of areas for storing zeolite, and both sides are encapsulated with filter meshes to facilitate the desorption of organic matter in the VOCs exhaust gas and allow the gas to pass through the runner 7. The first mounting frame 7 is installed in the filter box 1 by bolt connection. The filter box 1 is provided with a first mounting frame 5, wherein the first mounting frame 5 is provided with a motor 6 by bolt connection, and the output shaft of the motor 6 is fixedly connected to the impeller 7 by a key, and an adsorption component for absorbing organic matter is connected to the support plate 4, and a reaction reflux component for heating zeolite is also connected to the support plate 4, and the filter box 1 is connected to and communicated with a fourth air duct 22 at one side away from the air inlet 2, and the fourth air duct 22 is connected and communicated with the exhaust pipe 2201, and further comprises a guide frame 23, a baffle 24 and a first elastic member 25, and a guide frame 23 is provided with two baffles 24 on the side of the filter box 1 by bolt connection, and four first elastic members 25 for pushing the baffles 24 are arranged around the guide frame 23.

[0029] See also Figure 2-Figure 5 As shown, the adsorption assembly includes a first air guide cabinet 8 installed on the side of the support plate 4 close to the first mounting frame 5 by bolt connection, a blower 11 is installed on the second mounting frame 10 by bolt connection, the blower 11 is connected to the first air guide cabinet 8 and is connected to the first air guide pipe 9, and a reaction tank 14 for catalytic combustion of organic matter is installed on the support frame 13 by bolt connection, and the reaction tank 14 is connected to the blower 11 and is connected to the second air guide pipe 12.

[0030] See also Figure 2-Figure 6 As shown, the reaction reflux assembly includes a second gas guide cabinet 21 installed on the support plate 4 away from the first gas guide cabinet 8 by bolt connection, a conduction cabinet 17 is installed on the fixed frame 16 by bolt connection, a condensation plate 1701 is installed in the conduction cabinet 17, the conduction cabinet 17 and the second gas guide cabinet 21 are connected and communicated with a third gas guide pipe 20, the conduction cabinet 17 and the reaction tank 14 are connected and communicated with a first ventilation duct 15, a storage cabinet 19 for storing water is installed on the fixed frame 16 by bolt connection, the storage cabinet 19 is located directly below the conduction cabinet 17, and the storage cabinet 19 and the conduction cabinet 17 are connected and communicated with a second ventilation duct 18.

[0031] When it is necessary to treat the VOCs waste gas, the VOCs waste gas is introduced into the filter box 1 through the air inlet 2, and the VOCs waste gas is filtered through the filter layer 3. At this time, the motor 6 is started to drive the wheel 7 to rotate, and the zeolite in the wheel 7 adsorbs the organic matter in the VOCs waste gas. Then the blower 11 is started to extract the organic matter adsorbed by the zeolite through the first air duct 9, and the organic matter is transported to the reaction tank 14 through the second air duct 12 for reaction and combustion. After the reaction and combustion, carbon dioxide and water vapor are generated, and the carbon dioxide and water vapor are transported to the conduction cabinet 17 through the first ventilation pipe 15. The water vapor is liquefied and condensed through the condensation plate 1701, and the condensed water droplets are dripped into the storage cabinet 19 through the second ventilation pipe 18 for collection, and the carbon dioxide is transported to the second air duct through the third air duct 20 with residual temperature. In the cabinet 21, heat is transferred to the zeolite in the rotor 7 through the second air guide cabinet 21 to heat the zeolite, so that the zeolite continues to adsorb organic matter in the VOCs exhaust gas, and the gas after the zeolite desorbs the organic matter enters the exhaust pipe 2201 through the fourth air guide pipe 22, and the gas is discharged outward through the exhaust pipe 2201; when the filter layer 3 needs to be taken out, cleaned or replaced after long-term use, at this time, the baffles 24 on both sides are pulled to slide along the side of the guide frame 23 away from each other, and the first elastic member 25 is compressed and deformed by force to open the baffle 24, and then the filter layer 3 is slid out of the filter box 1, and the filter layer 3 is cleaned or replaced and put back into the filter box 1, and the baffles 24 on both sides are pushed to slide close to each other along the guide frame 23 by the first elastic member 25 to seal the filter layer 3 in the filter box 1.

[0032] Example 2: Based on Example 1, refer to Figure 8 As shown, it also includes guide rods 26 installed on both sides of the support plate 4 by bolt connection, and a cleaning plate 27 is slidably arranged on the guide rods 26. The cleaning plate 27 slides up and down along the guide rods 26. A second elastic member 29 for pushing the cleaning plate 27 to slide upward and reset is wound around the guide rods 26. A hook 30 is fixedly connected to the lower part of the cleaning plate 27 by welding, and a plurality of pulling rods 28 for pulling the hook 30 are fixedly connected to the circumference of both sides of the rotating wheel 7 by welding.

[0033] When the motor 6 drives the wheel 7 to rotate, the pulling rod 28 on the wheel 7 will contact the hook 30, and then pull the cleaning plate 27 to slide downward along the guide rod 26, so that the second elastic member 29 is compressed and deformed by force. As the wheel 7 continues to rotate, the pulling rod 28 will be separated from the hook 30. At this time, the second elastic member 29 loses the force and returns to its original state, thereby pushing the cleaning plate 27 to slide upward along the guide rod 26 to reset. Then the next pulling rod 28 repeats the above operation, so that the cleaning plate 27 can reciprocate and brush away the impurities on the filter screen of the wheel 7 to prevent the impurities from accumulating and clogging the holes of the filter screen of the wheel 7, thereby affecting the efficiency of the zeolite in adsorbing organic matter.

[0034] See also Fig. 9 As shown, it also includes a liquid storage cabinet 31 sleeved on the third air duct 20, a water inlet 33 and a water outlet 34 are provided on the liquid storage cabinet 31, and a thermometer 32 for detecting water temperature is embedded in the liquid storage cabinet 31.

[0035] When carbon dioxide enters the third air duct 20 through the third air duct 20, the residual heat of the carbon dioxide may not be sufficient to heat the zeolite on the runner 7. At this time, hot water is introduced into the liquid storage tank 31 from the water inlet 33, and the carbon dioxide in the third air duct 20 is heated by the hot water. The water after heat conduction is discharged through the water outlet 34, and the current hot water temperature in the liquid storage tank 31 can be known through the thermometer 32.

[0036] See also Figure 7 and Fig. 9 As shown, a plurality of sealing gaskets 35 for preventing gas leakage are installed on the side of the filter box 1 by bonding, and the sealing gaskets 35 are located between the baffle 24 and the filter box 1; a limit frame 36 is installed on both baffles 24 by bolt connection, and a pin 37 for fixing the limit frame 36 is slidably provided on the filter box 1.

[0037] The sealing gasket 35 is used to fill the gap between the filter box 1 and the baffle 24 to prevent leakage of VOCs waste gas input into the filter box 1; when the two baffles 24 are pulled apart to both sides, the common pin 37 is inserted through the limit frame 36 and the filter box 1 to limit the limit frame 36 to prevent the first elastic member 25 from pushing the baffle 24 to close the filter box 1, so as to facilitate the removal of the filter layer 3.
