Method for treating industrial organic waste gases

Abstract

The invention belongs to the technical field of waste gas treatment and relates to a method for treating industrial organic waste gases. In the method, a combination of screen mesh water removal, dielectric barrier discharge plasma and activated carbon fiber adsorption is adopted to treat the industrial organic waste gases, a screen mesh water remover removes liquid drops from the waste gases to ensure the normal operation of the following dielectric barrier discharge plasma, a double dielectric barrier discharge plasma reaction tube is adopted to solve the problem of electrode corrosion by allowing the treated gases to pass through between inner and outer tubes, and high-activity groups generated in reaction, undecomposed organic matters and oxygen in the gases are absorbed in the microporous structure of activated carbon fibers under the absorption and medium actions of the activated carbon fibers to ensure the activated carbon fibers is always in an activated state. The method has the advantages that: the treatment system is compact in structure; the energy efficiency is high; the treatment effect is desirable; and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and relates to an industrial organic waste gas treatment method, in particular to a novel organic waste gas treatment process technology which organically combines a dielectric barrier discharge plasma technology and an activated carbon fiber adsorption oxidation bed. Background technique [0002] Industrial organic waste gas generally contains volatile organic pollutants such as "triphenyl" (benzene, toluene, xylene), aldehydes, halogenated hydrocarbons, polycyclic aromatic hydrocarbons, and organic sulfides. In addition to chemical, paint production and mechanical product spraying, publishing and printing, sewage pumping stations and sewage treatment processes, there are also small pollution sources that can be seen everywhere in daily life, such as interior decoration paints and automobile exhaust. Studies have shown that organic pollutants can basically be divided into two categor...

AI Technical Summary

Problems solved by technology

[0006] 1. Some exhaust gases contain excessive water vapor, which has an adverse effect on the dielectric barrier discharge process

[0007] 2. The tail gas after dielectric barrier discharge plasma treatment contains a large amount of ozone, which cannot be fully utilized and causes secondary pollution;

[0008] 3. The discharge area is small, the gas reaction time is short, and the pollutants will be discharged with the exhaust gas if they fail to fully react
