Industrial oil fume and exhaust gas purification scheme for Jiangxi Electronics Factory
Keywords: Industrial oil fume purification, exhaust gas purification,
Oil containing waste gas can cause serious air pollution. After some substances enter the atmosphere, they form photochemical smog under certain conditions, causing secondary pollution. After entering the stratosphere, some substances undergo photochemical reactions with ozone under ultraviolet radiation, resulting in the formation of holes in the ozone layer. Some substances have dual properties of odor pollution and harmful gases. There are also some that can cause greenhouse effect.
This type of oil fume is difficult to handle and can be treated by adsorption or other electrostatic methods, but cannot be purified using cloth bags. If the oil particles are large, gravity method can be used for pretreatment, and then adsorption method can also be used
1. Liquid absorption method:
2. Adsorption and catalytic combustion methods:
3. Low temperature plasma UV photolysis integrated machineWaste gas treatment equipment
4. Direct combustion method
The treatment device for oily waste gas includes a biological purification treatment device, a circulating water pump, an oil-water separator, and a sewage pipe.
1. Oil containing waste gas inlet, 2. Microbial treatment layer, 3. Packing, 4. Spray device, 6. Low concentration waste gas outlet (closed during purification treatment, opened after several cycles), 8. Separation liquid inlet, 9. Oil water separator, 10. Waste oil pipe, 12. Circulating water pump (water flows upward), 13. Mixed liquid outlet; 14- Circulating water tank.
The activated carbon adsorption tower is designed with adsorption time based on different gas pollution factors, and the adsorption area is determined based on the amount of treated waste gas. Each project is a completely new design scheme. At the same time, according to the characteristics of the exhaust gas emitted in different production processes, such as exhaust gas temperature, whether it contains oil mist, dust and other related parameters, pre-treatment devices or functional sections such as coolers and filters are built or added to the inlet of the exhaust gas equipment. It effectively protects the adsorption section and ensures the efficient operation of the adsorption tower.
