High-efficiency activated carbon attachment device can quickly absorb pollutants in exhaust gas. The exhaust gas containing pollutants is powered by a fan and enters the activated carbon adsorber under negative pressure. Since there is unbalanced and unsaturated molecular attraction or chemical force on the solid surface of activated carbon, when the solid surface comes into contact with the gas, it can attract The gas molecules are concentrated and kept on the solid surface, and the pollutants are thus adsorbed. After the exhaust gas passes through the filter, it enters the dust exhaust system of the equipment, and the purified gas is discharged at high altitude to meet the standards.
