Suzhou olefins | rubber occupational waste gas treatment:

A large amount of organic waste gas will occur in the rubber industry. The exhaust gas is characterized by large emissions and complex and variable pollution components. Rubber waste gas contains malodorous substances, which can stay in the air for a long time and cause various adverse effects. And the rubber material production occupation is the first batch of occupations in China to test the emission of volatile organic compounds (VOC) in the atmosphere, which shows its importance.

Rubber waste gas treatment:

The origin of rubber production of VOCs

Organic waste gas that occurs during rubber mixing;

Organic waste gas during dipping and drying of fiber fabric;

Organic waste gas that occurs during calendering;

Organic waste gas generated in the vulcanization process;

Organic waste gas that occurs when ingredients, storage, and storage of resins, solvents, and other volatile organic compounds.

Rubber waste gas treatment equipment

The specific origins have the following three aspects:

(1) Release of residual organic monomer. Raw rubber such as natural, butyl benzene, cis-butyl, butyl, ethylene-propylene, chloroprene rubber, etc., the monomer has great toxicity, under the conditions of high temperature thermal oxidation, high temperature plasticizing and burning, these raw rubber dissociate a small amount of Monomers and hazardous compounds, mainly alkane and olefin derivatives.

(2) Volatilization of an organic solvent. Rubber is commonly used as an organic thinner for gasoline.

(3) Thermal reaction product. The rubber product is produced under high temperature conditions, which is easy to cause thermal reaction between various chemical substances and constitute a new compound.

Rubber professional VOCs treatment technology

In the exhaust gas produced by rubber, some effective treatment methods have been formed. However, due to different treatment methods of exhaust gas, the treatment is different from the advantages and disadvantages. Common methods include thermal combustion, biological treatment and catalytic oxidation. Law, etc., Zhongming Environmental Protection today focuses on the photocatalytic oxidation differentiation method.

Process: Exhaust gas - pipeline collection - spray tower - photocatalytic equipment - fan - chimney (clean air discharge)

After the exhaust gas is collected through the pipeline, it enters the spray tower. The spray tower can wash away the dust and part of the exhaust gas. After the spray treatment, it enters the photo-oxidation catalytic equipment, and the photo-oxidation catalytic equipment cracks and oxidizes and differentiates the organic waste gas. The core component of the photo-hydrogen ion purification in the rubber waste gas treatment equipment is the imported 253.7-nm two-photon wave generating tube. The photocatalytic reaction of the nano-photocatalytic nano-titanium is reflected by the nanophotonic generating tube, and a large amount of hydrogen peroxide is generated together. , oxygen ions, OH- and a large number of negative ions to achieve the purpose of purifying the air.

Rubber occupational emission standards

In order to control the pollution of the rubber occupation to the environment, the state standardized the rubber production process, and issued the "Rubber Products Industry Pollutant Discharge Specification (GB27362-2011)", which made specific rules for the rubber occupational pollutant emission regulations.
