Ultraviolet UV photolysis ozone purifier acrylic waste gas treatment equipment
Product overview
UV photolysis purification equipment is our company to introduce advanced technology from abroad, and many well-known domestic institutions to cooperate actively, a rapid and efficient removal of volatile organic compounds in joint research and development production of high-tech environmental protection equipment (VOC), inorganic compounds, ammonia, hydrogen sulfide, mercaptan, benzene and other pollutants all the smell. The deodorization efficiency can reach more than 99.9%, deodorizing effect more than the national emission standards for odor pollutants, it has strong adaptability, low operation cost, no characteristic of pretreatment and equipment covers an area of small, UV photolysis purifying equipment widely used in refinery, rubber factory, chemical factory, pharmaceutical factory, sewage treatment plants, garbage transfer station and other pollution source malodorous gas deodorization purification, its not suitable for Biotechnology amine, benzene waste paint odor in addition to organic waste gas.
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.
Ozone production process as follows:
UV +, O- + air + O2 and other negative ion - negative oxygen ion O3-, ozone O3
2, • OH (hydroxyl radical) production:
This device can also use ultraviolet beam and nano TiO 2 role produced • OH, dissolved in water ozone can also produce • • OH.
UV + H 2 O + TiO 2 • • OH
O 3 +H 2 O - OH
• OH (hydroxyl radical) is one of the most active oxidants, oxidation ability is significantly higher than ordinary oxidants, and malodorous gas reaction, higher degree of mineralization. The oxidation potential of several oxidants is as follows:
Oxidant reaction oxidation potential /V
• OH • OH+H + +e - H 2 O 3.06
O 3 O +2H + +2e - O 2 +H 2 O 2.07
H 2 O2 H 2 +2H + O + +2e - 2H 2 O 1.77
HClO HClO+H + +2e - Cl - +H 2 O 1.63
Cl 2 Cl 2 +2e - 2Cl - - 1.36
