>>Overview of UV photolysis exhaust gas purification equipment

UV photolysis is one of the methods for photocatalytic waste gas treatment. Photocatalytic method uses photoexcitation to separate the electrons and holes of the catalyst for oxidation and reduction of pollutants adsorbed on it. A large number of studies and customer cases prove that UV light catalysis has a good degradation effect on benzene, toluene, styrene, formaldehyde, acetaldehyde, ethylene, n-hexane, ammonia, hydrogen sulfide, mercaptans, etc. It has high reaction efficiency, easy recovery, small device footprint, and simple operation, and is particularly suitable for low-concentration exhaust gas treatment.

>>UV photolysis purification basic principles

l  The high-voltage power source excites the UV light to emit light, and generates a high-energy UV light beam. The ultraviolet light in a specific band (253.7nm) decomposes the molecular chain of the malodorous gas, breaking its large molecular structure into a small molecular structure.

l  UV light in a specific band (185nm) of the ultraviolet band causes oxygen molecules in the air to generate free oxygen, that is, active oxygen. Because the positron and negative electrons carried by free oxygen are not balanced, they need to combine with oxygen molecules to generate ozone. Ozone has extremely strong oxidizing properties, and has a strong elimination effect on malodorous gases. Finally, through the superposition of multiple effects, the malodorous gas molecules are oxidized into inorganic substances such as CO2 and H2O.

lUnder normal circumstances, TiO2 coating is added in the reaction chamber. Under the action of a catalyst (TiO2), ozone will oxidize the broken odorous gas molecules into inorganic substances such as CO2 and H2O.
