The activated carbon adsorption tower of the exhaust gas treatment equipment is under the action of the main fan of the system. The exhaust gas enters the pretreatment equipment or functional section of the gas tank from the air inlet of the tower body. Each adsorption unit entering the tower body; the surface force of the high-performance activated carbon adsorbent solid itself is used to attract the adsorbent of the organic waste gas molecules to the adsorbent surface, and the cleaned gas after adsorption passes through the adsorption unit into the tower body. The clean air chamber is collected at the air outlet and discharged. It can adsorb and purify the exhaust gas of organic solvents such as benzene, alcohol, ketone, ester, gasoline and so on. It is more suitable for the operating environment with low concentration and large air volume or high concentration intermittent exhaust gas. The environment, to ensure the health of workers, and to meet emissions standards.
At present, the methods for treating benzene organic waste gas by the waste gas treatment equipment mainly include adsorption method, catalytic combustion method, activated carbon adsorption + catalytic combustion method, and the like. Taking into account the feasibility of the method, operating costs, equipment investment costs and other issues, appropriate treatment methods should be selected. After discussion, exploration and development, our company has developed a simple operation, low investment, and low operating cost treatment process, activated carbon adsorption tower. This device has achieved satisfactory results in the treatment of organic waste gas containing toluene and reached the emission standards of environmental protection departments. .
