[0002] Waste gas treatment refers to the pre-treatment of waste gas generated in industrial sites and factory workshops before external discharge in order to meet the national standards for external waste gas discharge. Generally, the zeolite drum is a device that adsorbs volatile organic compounds in waste gas. It is divided into adsorption zone, desorption zone, cooling zone and regeneration zone. The zeolite drum rotates at a certain speed and operates continuously in each of the above zones. The waste gas enters the zeolite drum through the waste gas inlet, and then the adsorption zone of the zeolite drum adsorbs and removes volatile organic compounds in the waste gas. The purified waste gas is discharged from the treatment zone of the zeolite drum. The organic matter adsorbed in the zeolite drum is desorbed by preheating gas treatment in the desorption zone and sent to the catalytic combustion device for treatment;
