Working principle of activated carbon adsorption device

Adsorption of exhaust gas by activated carbon: During the activation process, the large surface area and complex pore structure are gradually formed. The surface area of ​​activated carbon is mainly provided by micropores. The adsorption of activated carbon can be divided into physical adsorption and chemical adsorption, and the adsorption process is exactly Conducted in these pores and on the surface, the porous structure of the activated carbon provides a large amount of surface area, making it very easy to absorb the collected exhaust gas. Just like magnetic force, all molecules have mutual attraction. Because of this, a large number of molecules on the pore walls of the activated carbon can generate strong gravitational force, so as to attract the paint exhaust gas in the medium to the pores, which is physical adsorption. It must be pointed out that the diameter of the adsorbed exhaust gas molecules must be smaller than the pore size of the activated carbon, so that it is possible to ensure that the impurities are absorbed into the pores. Activated carbon contains not only carbon but also a small amount of chemically bonded, functional groups of oxygen and hydrogen on its surface, such as carboxyl groups, hydroxyl groups, phenols, lactones, terpenes, ethers, and the like. These surfaces contain a ground oxide or complex which can chemically react with the adsorbed substance to bind to the surface of the activated carbon in combination with the adsorbed substance. The exhaust gas after the post treatment of zui is vacuumed by the rear centrifugal fan to form a negative pressure, which is safely discharged from the ground 15 m chimney and reaches the atmosphere.

Because of the mutual attraction between the molecules, when a molecule is captured by the inner pores of the activated carbon into the voids of the activated carbon, more molecules are attracted to each other due to mutual attraction between the molecules until the activated carbon is filled. The inner gap is up.
