In the process of vulcanization of rubber products, perhaps in the process of waste rubber regeneration, some vulcanization waste gas will affect the surrounding environment and also affect the health of workers. The main components of these waste gas are: non methane hydrocarbon, hydrogen sulfide, sulfur dioxide, odor, smoke, particles, etc. Because this sulfuration waste gas is discharged intermittently, it is difficult to use simple spray method or water filtration method for useful treatment.
Previously, activated carbon adsorption was selected for rubber vulcanization waste gas, and the main treatment fields include: production of electronic components, production of batteries (batteries), pickling workshop, laboratory exhaust, metallurgy, chemical plants, pharmaceutical manufacturers, coating workshops, food and brewing, furniture production, etc. It is especially suitable for waste gas treatment of rubber vulcanization, foaming and rubber refining processes in rubber industry, tire industry, seal manufacturing enterprises, rubber and plastic industry, etc.
It is mainly to use the adsorption characteristics of activated carbon to adsorb the waste gas of organic solvents such as benzene, alcohol, ketone, ester and gasoline. However, since the activated carbon after full adsorption is a hazardous waste, it needs to find a professional solid waste or hazardous waste treatment unit for treatment, and a hazardous waste treatment agreement needs to be signed, so the activated carbon adsorption has been gradually used by others Waste gas treatment equipment Instead, before understanding the rubber vulcanization waste gas treatment equipment, let's first understand in which process the waste gas mainly occurs.
1. Feed inlet: under the effect of mechanical kneading and high temperature, a certain amount of odorous and dusty waste gas escapes from the rubber in the internal mixer. The waste gas is collected by the smoke collecting hood at the feed inlet, filtered by the bag filter, and discharged through the fan.
2. Discharge outlet: the rubber in the internal mixer is discharged after mechanical kneading, and a lot of odorous and dusty waste gas occurs. The waste gas is collected by the smoke collecting hood at the discharge outlet, filtered by the bag type dust collector, and discharged through the fan.
3. Precondition of high section (i.e. compression section and cooling section): after the rubber mixture is discharged from the internal mixer, it is rolled to form a hot film, which is sent to the front elevating equipment after being soaked in the separator. In the front elevating equipment, the odor steam formed after the separation liquid on the hot film evaporates is collected by the smoke collecting hood set on the front elevating equipment, and is discharged through the fan.
Rubber waste gas and rubber vulcanization waste gas are relatively large, and the waste gas composition contains malodorous substances. The rubber vulcanization waste gas treatment process selected by Tianhaoyang Environmental Protection Co., Ltd. is as follows: waste gas collection ->spray purification ->UV photolysis purification equipment ->centrifugal fan ->qualified discharge from a 15m chimney. A variety of combined processes are selected to collect and purify effectively, Ensure that the production and operation of the enterprise are outstanding, improve the environment of the workshop and the plant area, and the emissions meet the national environmental protection requirements.
