Abstract

The invention discloses a Chipton production tail gas treatment method, and relates to the technical field of tail gas treatment. Chipton workshop production tail gas undergoes flash evaporation drying, and organized dichloroethane-containing tail gas is mainly treated with a two-box and four-core active carbon fiber adsorption treatment device and then is treated with a three-box and two-stage active carbon particle adsorption treatment device; disorganized dichloroethane-containing tail gas is mainly treated with a two-box active carbon particle adsorption treatment device; workshop o-methylphenol and other tail gases undergo alkali washing, demisting and hydrogen peroxide catalytic oxidation treatments; and the finally obtained device tail gases are mixed, then enter a photocatalytic oxidation device and are treated. The method reduces tail gas pollutants from the source; unitization separation and targeted optimization of the tail gas treatment simplify the tail gas treatment process, reduce labor and reduce the economic investment; and Chipton production tail gas can be discharged into air after being treated, so the pollution is reduced.

Description

Technical field: [0001] The invention relates to the technical field of waste gas treatment, in particular to a method for treating tail gas produced by dimethyltetrachloride. Background technique: [0002] The dimethyltetrachloride workshop has many posts in the production process, and the organic waste gas generated by each section mainly includes: dichloroethane and o-cresol. At present, the general production workshop has installed a water ring vacuum system and an absorption tower to absorb the volatile substances discharged from the vents of each reactor. However, limited to the operation and operation characteristics of some sections of the site, the volatile organic compounds cannot be completely absorbed and purified, and further treatment is required. Purify, absorb and recover dichloroethane in waste gas. It can not only reduce pollution, protect the environment, but also realize recycling and achieve the purpose of saving resources. [0003] The fugitive disch...
