Description

Microwave catalytic spraying exhaust-gas treatment all-in-one

Technical Field

The spraying waste gas is characterized in that the waste gas generated by a paint spray booth mainly comprises paint mist and volatile organic waste gas, and atomized dust particles formed by paint mist liquid paint under the action of air pressure are sticky and easily adhered to a ventilation pipeline system and waste gas treatment equipment, so that the system is unstable in operation; meanwhile, if a large amount of paint mist is directly discharged, the surrounding environment is affected. According to the characteristics of the spraying industry, paint mist and triphen waste gas (benzene, toluene and xylene) in the spraying and drying processes are treated simultaneously so as to reach relevant emission standards specified by environmental protection.

In the existing waste gas treatment process, an activated carbon adsorption method is most commonly used, is suitable for treating low concentration, requires low temperature, humidity and dust content of malodorous gas to be treated, has a removal rate of generally more than 80 percent, and is difficult to regenerate because particulate matters exist in the adsorption process of simple activated carbon and can be blocked inevitably; the thermal combustion method is suitable for treating high-concentration and small-gas-amount combustible gas, the removal rate is about 95 percent, but the thermal combustion method is not suitable for the spraying industry generally; the washing method is used for waste gas which is easy to react, the removal rate is generally more than 80%, and a large amount of volatile gas which is difficult to dissolve and stable in chemical property exists in the paint spraying waste gas, so the washing can be only used as a pretreatment measure.
