An upper activated carbon adsorption cylinder 10 and a lower activated carbon adsorption cylinder 9 are respectively arranged at the top and bottom of the partition 8. An exhaust valve is provided in the middle of the partition 8. Pipe 11, exhaust pipe 11 is fixedly connected to waste gas treatment box 2, and one end of exhaust pipe 11 passes through waste gas treatment box 2, and the other end of exhaust pipe 11 is rotatably sealed with rotating drum 6. Exhaust pipe 11 located inside rotating drum 6 has an exhaust port 23 at the bottom. Rotating drum 6 has an upper air inlet 14 and a lower air inlet 15 respectively. Rotating drum 6 has an assembly port 17 directly opposite the upper activated carbon adsorption cylinder 10 and the lower activated carbon adsorption cylinder 9. The assembly port 17 facilitates the disassembly and assembly of the upper activated carbon adsorption cylinder 10 and the lower activated carbon adsorption cylinder 9.

[0025] The upper activated carbon adsorption cylinder 10, the lower activated carbon adsorption cylinder 9, and the exhaust pipe 11 are all tightly connected to the inner wall of the partition 8 to prevent exhaust gas from leaking out between the upper activated carbon adsorption cylinder 10 and the rotating cylinder 6 or between the lower activated carbon adsorption cylinder 9 and the rotating cylinder 6, and to achieve a rotational seal between the rotating cylinder 6 and the exhaust pipe 11 during the rotation process.

Industrial waste gas is conveyed to the adsorption tank 1 through the waste gas conveying pipe 3 and discharged through the outlet 4 on the waste gas conveying pipe 3. Pollutants in the waste gas fully contact the adsorption liquid and undergo a neutralization reaction. Then, the waste gas enters the rotating drum 6 through the lower inlet 15. After odor adsorption by the activated carbon in the lower activated carbon adsorption cylinder 9, the gas enters the exhaust pipe 11 through the outlet 23 at the bottom of the exhaust pipe 11 and is finally discharged outwards from one end of the exhaust pipe 11. When it is necessary to... When replacing the lower activated carbon adsorption cylinder 9, simply start the motor 13. The motor 13 drives the rotating cylinder 6 to rotate 180° quickly via the rotating shaft 12, so that the positions of the lower activated carbon adsorption cylinder 9 and the upper activated carbon adsorption cylinder 10 are quickly switched and put into use. Then, the operator can climb the ladder to the waste gas treatment box 2 and quickly pull the upper activated carbon adsorption cylinder 10 out of the compartment 8 from the assembly port 17.
