Plastic particle waste gas treatment process

The demand for plastic in modern life is increasing, and the recycling of waste plastic has become a trend. Recycling, washing and granulating waste plastic is a way to turn waste into treasure and reuse resources. But regeneration granulation process, when the temperature exceeds 200 ℃, low boiling point impurities, plasticizer and internal oxidation decomposition happens, produce a large number of harmful gas containing dust particles, which contained more organic material, such as benzene, toluene, styrene, chlorinated organic compounds and so on, these harmful gas polluting, direct emissions into the air would not only cause physical harm to workers, as well as pollution to the environment.

Principle of UV photolysis technology

Using UV purification equipment special high-energy UV ultraviolet radiation beam splitting decomposition oxygen molecules in the air to produce free oxygen (ros), and high-energy UV ultraviolet light and ozone to collaborative photolysis oxidation of organic waste gas, the stench gas material degradation into low molecular compounds, water and carbon dioxide, the purpose of purifying waste gas.

Advantages: efficient deodorization, deodorization efficiency up to 99%; Strong adaptability, can adapt to low, medium and high concentration, large volume, granulator exhaust gas treatment equipment manufacturers of different odor gas deodorization purification treatment; Stable product performance, stable and reliable operation, 24 hours a day continuous work; Low cost of operation, low energy consumption of equipment, no need for personnel management and maintenance, just regular inspection.

　　Application: apply to printing and coating factory, dyeing factory, electronics factory, plastics factory, paint factory, furniture factory, oil refineries, rubber factory, chemical plants, paper mills, tanneries, pesticide plant, pharmaceutical factory, food processing plants, fish meal feed mills, farms, slaughterhouses, the stench gas such as sewage treatment plant, waste transfer station, industrial waste gas purification treatment.

When the waste gas treatment equipment processes the spray paint waste gas, because the paint mist particles in the spray paint waste gas is small, the viscosity is big, easy adhesion material surface, must remove the paint mist before purifying the organic waste gas. The traditional method of removing paint mist must adopt washing spray chamber. According to the experiment and engineering practice, the spray paint waste gas treatment process can use the spray paint waste gas -- water curtain -- spray washing --UV photocatalytic oxidation -- induced draft fan -- high altitude emissions to complete the exhaust gas treatment up to the standard.
