Active carbon adsorption and desorption catalytic combustion device for VOCs (Volatile Organic Compounds)

The VOCs activated carbon adsorption and desorption catalytic combustion device comprises a combustion chamber, a combustion bed and an air inlet pipe, the circumferential side of the air inlet pipe penetrates through the two end walls of a preheating chamber in a sealed connection mode, the end of the air inlet pipe is fixedly connected with one end of a catalytic pipe, and one end of the catalytic pipe penetrates through the preheating chamber and the side wall of the combustion chamber in a fixedly connected mode. The middle of the catalysis pipe is located in the combustion chamber, the combustion bed is fixedly arranged on the bottom wall of the lower combustion chamber, a plurality of fire spraying openings are formed in the upper surface of the combustion bed, the other end of the catalysis pipe penetrates through the preheating chamber and the side wall of the combustion chamber, and the middle of the catalysis pipe is bent to be in an S shape. And gas in the preheating chamber can enter the combustio
