Description
Technical Field
The utility model relates to a tail gas treatment technology, in particular to a tail gas adsorption treatment system for amitraz production.
Background
The raw materials for producing the amitraz comprise trimethyl orthoester and 2, 4-dimethylaniline, wherein the raw materials firstly generate intermediate imidoester, and then the imidoester reacts with N-methyl formamide to generate the amitraz. The boiling point of the triethyl orthoformate is 143 ℃, and the triethyl orthoformate is dissolved in ethanol and diethyl ether and slightly dissolved in water; 2, 4-dimethylaniline has a boiling point of 218 ℃ and is dissolved in ethanol, diethyl ether, benzene and acid solution and slightly dissolved in water; n-methyl formamide has boiling point of 180-185 deg.c, and is soluble in water and alcohol and insoluble in ether; the intermediate iminoester has a boiling point of 185 ℃ and is insoluble in water.
In the feeding process of producing amitraz, raw materials of raw methyl ester triethyl and 2, 4-dimethylaniline are vaporized to form tail gas due to vacuum feeding and high-temperature reaction; the intermediate imidoester formed in the reaction is gasified to generate tail gas by high temperature reaction with N-methyl formamide. And because the boiling points of the raw materials are high, the tail gas contains high-boiling-point substances, and the treatment is difficult. At present, the treatment mode for tail gas is two-stage water washing and active carbon adsorption, but because the tail gas contains the raw materials and related intermediates, most of the tail gas is slightly soluble in water or insoluble in water, so that the water washing effect is small, the water resource waste is high, the tail gas is mainly treated by the active carbon adsorption, the active carbon needs to be replaced frequently, a large amount of waste is generated, and a large amount of waste is also caused.
