Embodiment Construction

[0033] Treatment of waste gas experiment

[0034] Take the exhaust gas containing dimethylamine as an example, the gas volume is 4000m 3 / h, concentration 1000mg / m 3 , the gas temperature is between 30°C and 70°C, and the water vapor is supersaturated. After the organic gas containing dimethylamine is collected, it first passes through the screen dehydrator (this unit can be omitted if there is no water vapor) to remove water vapor, and then enters the dielectric barrier discharge plasma reactor, where the bombardment of high-energy electrons is used , make the pollutants undergo a series of reactions, decompose and convert them into carbon dioxide and water or harmless substances, a small amount of undecomposed organic substances, O produced during the reaction process 3 , O and HO · and O 2 When passing through the activated carbon fiber bed, it is adsorbed by the activated carbon fiber and continues to react. Through the adsorption and accumulation of activated carbon f...

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...
