Therefore, the nation sets up strict exhaust emission standards, and the traditional exhaust pollution treatment technologies include an adsorption method, a condensation method, a biological method, a combustion method and the like, which are relatively laggard and difficult to achieve the expected treatment purpose.
The UV photolysis purification process utilizes high-energy ultraviolet light beams to irradiate molecular bonds of malodorous gases (industrial waste gases) to crack malodorous gas substances such as: benzene, toluene, xylene, non-methane total hydrocarbons, esters and the like, ammonia, trimethylamine, hydrogen sulfide, methylthio hydrogen, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene, sulfide and other VOC gas molecular bonds, so that pollutant atoms in a free state and ozone are oxidized and polymerized into small-molecule harmless or low-harmful substances, such as CO2、H2O, and the like.
The specific working mechanism is as follows:
1. the molecular bond in the malodorous gas is cracked by using high-energy 253.7nm UV light beams (254 nm for short) to change the malodorous gas into extremely unstable C bond, -OH and O ions.
2. Decomposing oxygen molecules in the air by using high-energy high-ozone 185nmUV ultraviolet light beams to generate free oxygen, namely active oxygen, wherein the free oxygen needs to be combined with the oxygen molecules because positive and negative electrons carried by the free oxygen are unbalanced, and then ozone is generated; UV + O2→O-+O＊(active oxygen), O + O2→O3(ozone), which polymerizes with the atoms of the pollutants in the free state to form new harmless or low harmful substances, such as CO2、H2O, etc., has instant effect of removing malodorous gas and other pungent odor.
