When the exhaust gas is powered by a fan and enters the adsorption box under negative pressure, it enters the activated carbon adsorption layer. Due to the unbalanced and unsaturated molecular gravity or chemical bond force on the surface of the activated carbon adsorbent, when the surface of the activated carbon adsorbent comes into contact with gas, it can attract gas molecules, concentrate and maintain them on the surface of the activated carbon. This phenomenon is called adsorption. By utilizing the adsorption capacity of activated carbon adsorbent surface, the exhaust gas is brought into contact with the porous activated carbon adsorbent on the large surface. The pollutants in the exhaust gas are adsorbed on the surface of the activated carbon, separated from the gas mixture, and purified before being discharged.

Scope of application of activated carbon adsorption device:
The treatment of organic waste gas with high air volume and low concentration can treat benzene, ketones, alcohols, alkanes, and their mixed organic waste gases. It is mainly used for the purification and treatment of harmful waste gases generated in chemical, mechanical, electronic, electrical, painting, shoemaking, rubber, plastic, printing, and various industrial production workshops. Activated carbon adsorption device utilizes the surface force of high-performance activated carbon adsorbent solid itself to attract and attach the adsorbate of organic waste gas molecules to the surface of the adsorbent. It can adsorb waste gases of organic solvents such as benzene, alcohols, ketones, esters, and gasoline, and is more suitable for the treatment of high air volume and low concentration waste gases. It is suitable for industries such as electronics, chemical industry, light industry, rubber, paint, coating, printing, machinery, ships, automobiles, and petroleum.
