Technical principle
There are unbalanced and unsaturated molecular gravitation or chemical bond force on the surface of activated carbon. When activated carbon contacts with gas, it can attract gas molecules and make them concentrate and keep on the solid surface. This phenomenon is adsorption. By using the adsorption capacity of activated carbon surface, the waste gas contacts with the porous solid material on the surface, and the pollutants in the waste gas are adsorbed on the solid surface, so that it can be mixed and separated with the gas to achieve the purpose of purification.
