Activated carbon adsorption and desorption organic waste gas treatment device

Abstract

The invention discloses an activated carbon adsorption and desorption organic waste gas treatment device. The device comprises a waste gas treatment tank and a desorption tank which share a same sidewall; a horizontal sliding rail is arranged on the inner wall of the waste gas treatment tank, an activated carbon box is slidably arranged on the horizontal sliding rail; the activated carbon box isprovided with a weighing ring, and the weighing ring can be used for weighing a bottom plate and activated carbon; a plurality of iron blocks are arranged on one side of a box wall frame; an electromagnetic push device is arranged outside the side, corresponding to the iron blocks of the activated carbon box, of the waste gas treatment tank; the electromagnetic push device can push the activated carbon box to move between the waste gas treatment tank and the desorption tank back and forth. The device has the advantages of being simple in structure, capable of saving manpower and good in organic waste gas treatment effect.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to an activated carbon adsorption-desorption organic waste gas treatment device. Background technique [0002] At present, my country's ambient air pollution is becoming more and more serious, and the frequency of heavy pollution such as smog and haze is increasing day by day. Ozone and PM2.5 have become the "culprit" and "main culprit" of urban air pollution, while VOCs (volatile organic pollutants) are the common precursors of fine particles such as ozone and PM2.5. VOCs have the characteristics of low concentration and high toxicity, and are called "shadow killers". Therefore, the research on the treatment of organic waste gas containing volatile organic compounds (VOCs) has gradually received more and more attention. [0003] At present, the commonly used processes in the treatment of organic waste gas mainly include: adsorption method, absorption metho...

AI Technical Summary

Problems solved by technology

Compared with activated carbon adsorption, spray absorption and other methods, the oxidation method structurally destroys the organic components, decomposes organic pollutants relatively more thoroughly, and is less likely to cause secondary pollution, but there is also the problem of low waste gas treatment efficiency

Activated carbon adsorption has strong adaptability, and is suitable for the purification treatment of most high-concentration, large-volume, and different organic substances. However, activated carbon adsorption is saturated, and it is necessary to replace activated carbon regularly, which is more troublesome.
