The present invention completely degrades organic waste gas by means of catalytic combustion, degrades waste gas pollutants into low-molecular harmless substances, can also effectively reduce reaction temperature, improve equipment safety, and reduce operating costs; by adsorbing activated carbon boxes, Desorption can transform large-volume low-concentration exhaust gas into small-volume high-concentration exhaust gas, which can greatly reduce the scale of subsequent treatment devices, thereby reducing investment, long service life, low maintenance and replacement costs, and the entire set of devices adopts automatic control and easy operation and management. .
