Principle of photocatalytic equipment technology: 185 nm band and 253.7 nm band are combined to produce C band (185 nm band) ultraviolet light in the treatment unit by using ultraviolet tube. The ultraviolet radiation in this band produces a large number of hydroxyl radicals for the irradiation of water vapor and oxygen in the exhaust gas of the device. OH radicals have some oxidation potential (2.80EV). Its oxidation ability is very strong. It can react with most organic pollutants in a fast chain way. It can oxidize harmful substances into CO 2, H 2 or mineral salts without selectivity. Ultraviolet ray tube is used to produce C band (253.7 nm band) ultraviolet rays in the treatment unit, which can destroy and crack the molecular chains of organic substances, change the structure of substances, and crack macromolecular substances. Under the action of C-band ultraviolet radiation, organic waste gases of less than 1000 PPM molecules can be cracked and oxidized into CO2 and H2O in only 0.5 s.
Photo-oxygen catalytic equipment, if the selection of air volume and configuration is accurate, can purify industrial waste gas to achieve environmental emission standards, but also does not produce secondary pollution.
The above is all about the principle of photocatalytic equipment technology, hope to help you, more information please pay attention to photocatalytic equipment manufacturers./
