Activated carbon filtering box for waste gas treatment

Abstract

The invention discloses an activated carbon filtering box for waste gas treatment. The activated carbon filtering box comprises a box body and two filter layers inside the box body. One end of the boxbody is provided with an air inlet, and the other end of the box body is provided with an air outlet. The two filter layers are arranged along the lengthwise direction of the box body and are perpendicular to the bottom surface of the box body. A gas flow channel is arranged between the two filter layers. Each filter layer includes an outer gas inlet surface and an inner gas outlet surface between the two filter layers. The air inlet and the outer gas inlet surface are communicated, the outer gas inlet surface and the inner gas outlet surface are communicated, and the inner gas outlet surfaceand the air outlet are communicated. The activated carbon filtering box increases the contact area between an activated carbon layer and waste gas, improves the processing amount of the waste gas perunit time, improves the adsorption efficiency, and facilitates regular replacement of the activated carbon layer, and saves manpower.

Description

technical field [0001] The invention belongs to the technical field of filter devices, in particular to an activated carbon filter box for waste gas treatment. Background technique [0002] Industrial waste gas usually contains pollutants such as benzene, toluene and sulfide, which are usually harmful to human health and the environment. For example, these pollutants enter the human body through breathing, skin contact and digestive tract, which will cause endocrine dysfunction and affect the human immune function, cardiovascular and central nervous system. Therefore, the issue of waste gas treatment has received great attention. [0003] Existing industrial waste gas filtration devices are usually equipped with activated carbon in the filter box. Due to the unbalanced and unsaturated molecular attraction or chemical strength on the solid surface of the activated carbon, when the solid surface is in contact with the gas, it can attract the gas. Molecules, so that they conde...

AI Technical Summary

Problems solved by technology

Although the adsorption effect is good and can be widely used, the contact area between activated carbon and exhaust gas is small, and the treatment capacity of exhaust gas per unit time is low. Moreover, after a period of use of activated carbon, the adsorption capacity decreases and it is inconvenient to replace.
