Process principle
In 2 TiO UV photolysis catalytic oxidation deodorizing device, high energy ultraviolet light and air, TiO 2 produced by the reaction of ozone, OH (hydroxyl radical) of malodorous gas CO oxidation decomposition reaction, and macromolecular malodorous gases under ultraviolet light to make the chain structure fracture, the malodorous gases into small molecular substances no odor compounds or complete oxidation, formation water and CO 2 standard, after the exhaust pipe into the atmosphere, the oxidation process is completed in seconds.
1, the production of ozone:
The use of high-energy ultraviolet light, causing a large number of free electrons in the air, these electrons can be obtained by most of the oxygen, the formation of negative oxygen ions (O 3), negative oxygen ion is not stable, it is easy to lose an electron into active oxygen (ozone), ozone advanced oxidation agent, can oxidation of organic substances the main odor and organic substance, ammonia, hydrogen sulfide, methyl mercaptan and hydrocarbon compounds, can react with ozone in the ozone under the action of the malodorous gas by large molecules is decomposed into small molecules, until oxidation.
The ozone production process is as follows:
The photocatalytic oxidation reaction, is to let the light photosensitive semiconductor catalyst sunlight or other energy, stimulate the occurrence of valence electronic semiconductor intersubband transitions from the valence band to the conduction band, resulting in the photogenerated electrons and holes (e-) (h+). The adsorption of dissolved oxygen in the surface of nano particle trapping electrons to form superoxide anion, and the hole will be adsorbed on the catalyst surface hydroxyl ions and water oxidation of hydroxyl radicals. The superoxide anion and hydroxyl radical with strong oxidation, can make almost all of the oxidation of organic pollutants to the final products of CO2 and H2O, but also completely decomposition of some inorganic pollutants, there is no adsorption saturation and two pollution problems.
UV photolysis adaptation range:
Application of UV photolysis catalytic oxidation technology in all kinds of chemical enterprises, including medical, spray paint, rubber, printing and dyeing, food and other chemical enterprises; sewage station gas; nitrogen compounds such as ammonia, amines, nitriles and nitro compounds, nitrogenous heterocyclic compounds, hydrocarbons, carbon or hydrogen;
Compounds, such as lower alcohols, aldehydes, fatty acids, etc.. The photolysis of UV catalytic oxidation technology investment; covers an area of small, easy to use, simple cleaning, convenient maintenance; impact load, not easily affected by the pollutant concentration meter temperature change; wide range of application, especially the removal rate of odor gas well
