Waste gas treatment device and system for chemical reaction kettle

Abstract

The invention discloses a waste gas treatment device and system for a chemical reaction kettle, and belongs to the technical field of chemical production; according to the scheme, the benzene steam isfiltered by the retractable filter ball; when the offset pull rod is in contact with the trigger switch, the first electromagnet and the second electromagnet attract each other, the whole retractablefiltering ball is temporarily retracted; when the offset pull rod is not in contact with the trigger switch, the retractable filter ball is continuously expanded, therefore, the retractable filter ball is continuously in a contracted and expanded state; the retractable filter balls are continuously contracted and expanded, so the filtering effect on distilled benzene steam can be improved; when the expansion balloon expands when heated, static electricity can be generated on the surface of the rubber ball through continuous friction of the fur layer on the rubber ball, so that the effect of collecting particles in benzene steam is improved, the content of the particles in the benzene steam can be reduced when coal tar containing benzene is separated, and the purity of the obtained benzeneis improved.

Description

technical field [0001] The invention relates to the technical field of chemical production, more specifically, to a waste gas treatment device for a chemical reaction kettle and a system thereof. Background technique [0002] The broad understanding of the reaction kettle is a stainless steel container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. The pressure requirements in the subsequent reaction process also have different requirements on the design of the container. Production must be processed, tested and tested in strict accordance with the corresponding standards. Stainless steel reactors vary according to different production processes and operating conditions. The design structure and parameters of the reactors are different, that is, the structural styles of the reactors are different, and they a...

Problems solved by technology

[0004] At present, when separating coal tar containing benzene, the generated coal tar and gas pass through washing and absorption equipment together, and high-boiling coal tar is used as washing and absorbent to recover the coal tar in the gas. After distillation, crude Benzene and other high-boiling point fractions, crude benzene can be refined to obtain industrial grade benzene, but during the distillation process, the benzene vapor will drive particles to float out, which will pollute the environment and make the condensed benzene impure
