[0002] In the process of waste treatment, the purification of waste gas is involved. Solid and liquid wastes contain some volatile organic compounds (VOCs). If released into the atmosphere, they will also produce odorous substances such as hydrogen sulfide (HS) and ammonia (NH) in the natural environment, which will evaporate into the atmosphere and cause serious air pollution. Therefore, further treatment is required before the waste gas is discharged.

[0003] After searching, the patent with publication number CN218221750U discloses an activated carbon exhaust gas purification self-cleaning device, including a functional shell and an adsorption cylinder fixed in the functional shell. The purpose of this utility model is to solve the problem that after the traditional activated carbon adsorption equipment has worked for a long time, the dust in the exhaust gas affects the penetration rate of the activated carbon adsorption equipment.

[0004] Although the above patent can effectively solve the problem of activated carbon adsorption plate clogging, the use of a motor to rotate the cleaning brush to clean the activated carbon adsorption plate increases the cost of the means used to solve the problem, which is not conducive to energy conservation and emission reduction.
