Introduction to the principle of UV oxidation waste gas treatment device

The UV oxidation exhaust gas treatment device uses high-energy ultraviolet radiation to destroy and decompose large molecular chains into small molecular chains, and then uses ozone and hydroxyl radicals for oxidation and catalytic oxidation with catalysts to convert organic matter into water and carbon dioxide, in order to achieve the goal of removing organic matter.

(1) Destruction cracking

By using microwave ultra strong electromagnetic radiation and penetration power, as well as microwave catalytic combustion function, the exhaust gas is subjected to microwave radiation and destruction, completely breaking down the molecular chains of all organic waste gases, cracking and changing the material structure, and decomposing high molecular pollutants into low-molecular-weight harmless substances such as water and carbon dioxide.

A specially designed ultraviolet light tube is used to generate high-energy C-band (253.7nm band) ultraviolet light in the processing device, which destroys and breaks down organic molecular chains, changes the material structure, and breaks down and oxidizes large molecular substances into low molecular weight substances or harmless substances, such as water and carbon dioxide. Under the action of high-energy C-band ultraviolet radiation, organic waste gas with a molecular weight below 1000PPM can be decomposed and oxidized into CO2 and H2O in just 0.5s.

(2) Triple catalytic oxidation

A specially designed ultraviolet light tube is used to generate C-band (185nm band) ultraviolet light in the treatment device. This band of ultraviolet light irradiates the water vapor and oxygen in the exhaust gas inside the device, producing a large amount of hydroxyl radicals. Due to its extremely high oxidation potential (2.80EV), hydroxyl radicals (OH) have strong oxidation ability and can undergo rapid chain reactions with most organic pollutants, selectively oxidizing harmful substances into CO2, H2O or mineral salts without secondary pollution.
