Problems solved by technology

[0003] Vulcanization is an essential process for synthetic rubber. During the vulcanization process, vulcanization waste gas will be generated. The vulcanization waste gas includes the waste gas generated during the opening of the tank and the waste gas generated during the pressure relief process of the vulcanization tank. People need to treat the vulcanization waste gas. The existing waste gas treatment Only the collection and discharge process in the waste gas treatment process is considered, and the energy recovery and treatment in the vulcanization process and the comprehensive utilization and treatment of water are not considered, which results in a waste of energy and resources

Abstract

The invention discloses a rubber vulcanizing waste gas treatment process. The process specifically includes following steps: step 1, spraying, cooling and drying waste gas generated by tank opening, and performing triple ultraviolet catalytic oxidation to obtain a first product; step 2, sequentially performing low-temperature plasma treatment, low-temperature high-energy plasma treatment and activated carbon absorbing treatment on the first product, and then discharging; step 3, feeding waste gas generated in the process when a vulcanizing tank releases pressure into a heat exchange tank connected with a heat exchange device until temperature of the waste gas is cooled to below 60 DEG C, and repeating the step 1 and the step 2 on the waste gas after being cooled. Comprehensive utilizationof heat and comprehensive utilization of reclaimed water are taken into consideration, so that boiler running cost in heating seasons is saved greatly, and comprehensive energy consumption of a factory in the heating seasons is lowered; sewage is recycled partly, so that outward discharge is reduced, consumption of underground water is reduced, and water vapor content in the process of waste gas emission is lowered.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a rubber vulcanization waste gas treatment process. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. Rubber is divided into two kinds of natural rubber and synthetic rubber. Early rubber was latex taken from plants such as rubber trees and rubber grasses. After processing, it was made into materials with elasticity, insulation, impermeability and air. Later, people began to artificially synthesize rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and ot...
