Exhaust gas treatment system from YangSunny's blog

To completely solve the problem of exhaust gas, waste oil to diesel or base oil recovery plant is equipped with three levels of treatment, including A)Spray device; B)Activated carbon adsorption ;C)UV photolysis,then introduce the functions separately:

A)Spray device

1) Removal of acidic pollutants: alkali washing can effectively remove acidic components in exhaust gas and reduce environmental pollution.

2) Purify the air: through the neutralization reaction, harmful gases are converted into harmless substances to improve air quality.

3) Protection equipment: to prevent acid gas corrosion of subsequent treatment equipment, prolong the service life of equipment.

B)Activated carbon adsorption

The exhaust gas enters the activated carbon adsorption unit, and the activated carbon rapidly absorbs the organic matter in the exhaust gas by its porosity and high specific surface area, thereby reducing the concentration of the exhaust gas

C)UV photolysis

1)UV photolysis equipment uses special high-energy, high-ozone ultraviolet beams to irradiate malodorous gases and crack malodorous gases such as ammonia, trimethylamine, hydrogen sulfide, sulfur, methyl mercaptan, methyl sulfide, and dimethyl siloxane , carbon disulfide and the molecular chain structure of styrene, benzene, toluene, xylene and other compounds that cause the odor of organic or inorganic polymers when exposed to high-energy ultraviolet beams.

2)High-energy, high-ozone ultraviolet beams are used to decompose oxygen molecules in the air to produce free oxygen. Because the electrons carried by positive and negative free oxygen are unbalanced, it needs to be combined with oxygen molecules to produce ozone. Ultraviolet + oxygen → O- + O* (free oxygen) O + O2 → O3 (ozone). As we all know, ozone has a strong oxidizing effect on organic matter and has an immediate effect on removing odorous gases and other irritating gases.

3)After the odorous gas is input into the purification device through the exhaust device, the purification device uses high-energy ultraviolet beams and ozone to collaboratively decompose and oxidize the odorous gas, thereby converting the odorous gas substances into low molecular compounds, water, carbon, and carbon dioxide, and then through the line . The air duct is discharged to the outside.

After three-stage process as above,the emission gas will be colorless, odorless and harmless,and release to the air with pollution to the enviroment.
