Activated carbon is a kind of very fine carbon particles with large surface area and granular and small bore capillary. The capillary has a strong adsorption capacity, due to the large surface area of carbon particle, so it can fully contact with the gas (impurities), when the gas (impurities) met capillary adsorption and purification. The essence of activated carbon adsorption is to use activated carbon adsorption characteristics of low concentration and large amount of air in the organic solvent adsorption to activated carbon. Activated carbon adsorption method is mainly used for the removal of low concentration gaseous pollutants.

When the exhaust gas is powered by the fan, negative pressure into the adsorption box into activated carbon adsorption layer, due to the adsorption of activated carbon agent on the surface there are no balance and unsaturated molecular attraction or chemical bonding force, so when the activated carbon adsorbent surface in contact with the gas, will be able to attract gas molecules the concentrated poly and remain on the surface of activated carbon. This phenomenon known as adsorption. Using activated carbon adsorption of surfactant adsorption capacity, the waste gas with large surface porous activated carbon adsorption agent contact, pollutants in the exhaust gas is adsorbed on the surface of activated carbon, making it and the separation of a gaseous mixture, purified gas discharge in the sky. Activated carbon adsorption box is a dry waste gas treatment equipment, composed of a box body and filled in the box body adsorption unit.

Activated carbon box is mainly used for the treatment of organic waste gas with low concentration of large air volume. Activated carbon adsorption agent can purify a variety of organic and inorganic pollutants: benzene, ketones, alcohols, ethers and alkanes and mixed type organic waste gas, acid gas, alkaline waste gas, mainly used to produce pharmaceuticals, metallurgy, chemical industry, machinery, electronics, electrical appliances, coating, footwear, rubber, plastics, printing and environmental desulfurization, deodorization, and various industrial production workshop of harmful exhaust gas purification treatment.

Characteristics of the environmental protection box performance of activated carbon 1, absorption of high efficiency, strong ability; 2, to simultaneously process a plurality of mixed organic waste gas; purification efficiency is greater than or equal to 95%; 3, the equipment is compact in structure, covers an area of small, simple maintenance and management, low operating costs; 4, the use of automation control in operation, simple operation, safety; 5, fully enclosed type, indoor and outdoor.
