Abstract

The invention provides a treatment method of waste gas produced by dicumyl peroxide. A waste gas treatment device used for the method comprises a collecting tank, an activated carbon adsorption tank, a condenser, a fluid container and a draught fan which are connected by virtue of pipelines. The treatment method comprises the processes of waste gas collection, adsorption treatment, desorption regeneration treatment, condensation layering and the like. The treatment method of waste gas produced by dicumyl peroxide, which is provided by the invention, is used for adsorbing and desorbing waste gas by activated carbon fibers so as to treat and recycle waste gas; compared with the traditional combustion and liquid absorption, the treatment method has the advantages that secondary pollution cannot be caused; meanwhile, the cost is relatively low; the treatment effect is excellent; the whole treatment method is capable of achieving the waste gas treatment efficiency of 95-99%; the finally emitted waste gas is lower than the national emission standard.

Description

technical field [0001] The invention relates to a method for treating waste gas, in particular to a method for treating waste gas produced by dicumyl peroxide, and belongs to the technical field of waste gas treatment. Background technique [0002] Dicumyl peroxide (DCP for short) is widely used in the chemical industry as an excellent initiator, vulcanizing agent and crosslinking agent in polymer materials such as natural rubber, synthetic rubber and polyethylene resin. At present, the industry mainly uses cumene as raw material to oxidize cumene hydroperoxide, and then reduces it with sodium sulfide to generate α,α-dimethylbenzyl alcohol, and then catalyzes hydrogen peroxide under the catalysis of perchloric acid. The condensation reaction between cumene and benzyl alcohol produces dicumyl peroxide. [0003] During the oxidation and condensation reaction, a large amount of exhaust gas pollutants will be produced, and the main ones are cumene and non-methane total hydrocar...
