Activated carbon box for waste gas treatment in workshop

Abstract

The invention discloses an activated carbon box for waste gas treatment in a workshop. The activated carbon box comprises a box body and two filter layers inside the box body. One end of the box bodyis 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 perpendicularto the bottom surface of the box body. A gas flow channel is arranged between the two filter layers. Each filter layer includes an inner gas inlet surface between the two filter layers and an outer gas outlet surface opposite to the inner gas inlet surface. The air inlet and the inner gas inlet surface are communicated, the inner gas inlet surface and the outer gas outlet surface are communicated, and the outer gas outlet surface and the air outlet are communicated. The activated carbon box increases the contact area between an activated carbon layer and waste gas, improves the processing amount of the waste gas per unit time, improves the adsorption efficiency, and facilitates regular replacement of the activated carbon layer, and saves manpower. When the filter layers are replaced or overhauled, the waste gas treatment in an entire waste gas treatment system is not affected.

Description

technical field [0001] The invention belongs to the technical field of filter devices, in particular to an activated carbon box for workshop 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 con...

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.
