Due to the development of China's industry, industrial waste gas is becoming more and more serious, and air pollution has become a thorny problem.Let me share with you how the exhaust gas treatment equipment works.

How does the waste gas treatment equipment work

1.Dilution diffusion method

How It Works: Odorous gases are released into the atmosphere through chimneys or diluted with odourless air to reduce the concentration of odourous substances, thereby reducing odour.Advantages: low cost, simple equipment.

2.Water absorption way

Principle: industrial waste gas treatment equipment uses the characteristics of some substances soluble in water in the odor, so that the odor components directly contact with water, so as to dissolve in water to achieve the purpose of deodorization.Advantages: simple process, convenient management, low cost of equipment operation, secondary pollution, need to deal with washing liquid.Disadvantages: low purification efficiency, should be used in combination with other technologies, mercaptan, fatty acid treatment effect is poor.

3.Deodorization method of aerated activated sludge

Principle: Malodorous substances are dispersed in a mixture containing activated sludge in the form of aeration. Suspend microorganisms have a wide range of applications in degrading malodorous substances.Advantages: after acclimation, the removal rate of odor components under load can reach more than 99.5%.

4.Multimedia catalytic oxygen chemical industry

Principle: The reaction column is equipped with special solid packing, which is mixed with multimedia catalyst.When the odorous gas passes through the packing layer under the action of an induced draft fan, the liquid-phase compound oxidant emitted by the industrial waste gas treatment equipment in the form of diffusion mist through a special nozzle is brought into full contact with the solid surface.Phase filling, the pollution factor in the odor is completely decomposed under the catalysis of catalyst.Advantages: small footprint, less investment, low operating cost;It is easy to manage and can be used immediately.

5.low temperature plasma

Cryogenic plasma is the fourth state of matter after solid, liquid and gas.When the applied voltage reaches the ignition voltage of the gas, the gas molecules break down to produce a mixture containing electrons, various ions, atoms and free radicals.Although the electron temperature is very high in the discharge process, but the temperature of the heavy particles is very low, the whole system is in a low temperature state, so it is called a low temperature plasma.In fact, low-temperature plasma pollutant degradation methods in industrial waste gas treatment facilities take advantage of these high-energy electrons, free radicals and other active particles in the waste gas and the effects of pollutants to decompose pollutant molecules in a short period of time and produce subsequent reactions.To achieve the purpose of degrading pollutants.

Low temperature plasma air purification equipment can significantly control pollution including volatile organic compounds, odor gas, odor gas, oil fumes and dust, but also can be used to sterilize and kill bacteria.Low temperature plasma technology is a new purification process.No additives are required, no waste water or residue is produced, and no secondary pollution is caused.
