Novel organic waste gas treatment method and device

Abstract

The invention relates to a novel organic waste gas treatment method and device. A modified activated carbon adsorbent is adopted, and organic matters in an organic waste gas is rapidly and effectivelyadsorbed by virtue of the high-speed adsorption capacity of the modified activated carbon adsorbent, so that organic pollutants are adsorbed on the surface of the adsorbent. Then, the modified activated carbon is sprayed and cleaned by using reactive oxygen water generated by a reactive oxygen generator, and the organic pollutants on the surface of the modified activated carbon are deeply oxidized, so that the organic pollutants are rapidly and thoroughly degraded to form substances harmless to the environment. Meanwhile, the organic pollutants adsorbed on the surface of the adsorbent are thoroughly removed, so that the adsorbent is always in an unsaturated state, and the regeneration demand is reduced. The adsorbent is not required to be backflushed in the operation process of the deviceand the method, and the organic pollutants in the waste gas can be rapidly and effectively oxidized in combination with reactive oxygen water during operation of the method and the device. The deviceis high in adaptability, high in treatment speed and greatly reduced in floor area.

Description

technical field [0001] The invention relates to a new treatment method and device for treating organic waste gas, belonging to the technical field of waste gas treatment. Background technique [0002] With the rapid development of industry and deep processing of agricultural products, the types and quantities of waste gas have increased rapidly, and the pollution of the atmosphere has become increasingly widespread and serious, threatening human health and safety. Among them, the treatment of organic waste gas is a major problem in the environmental protection industry. [0003] Organic waste gas is generally flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat. At present, various methods such as organic waste gas adsorption treatment method, catalytic combustion method, catalytic oxidation method, acid-base neutralization method, plasma method, etc. are commonly used in the market. [0004] However, the above...

AI Technical Summary

Problems solved by technology

[0004] However, the above methods have their own shortcomings: the plasma method adopts high-voltage discharge method, and the safety cannot be guaranteed in the treatment of flammable and explosive organic waste gas. There have been many explosions in the treatment of organic waste gas by plasma method; activated carbon adsorption The method cannot solve the problem of regeneration after adsorption saturation; both catalytic combustion method and catalytic oxidation method need to heat the exhaust gas to the reaction temperature of the cata
