Technical Principle Of UV Photolysis And Photocatalysis Products


Technical principle

A, products by using UV ultraviolet beam, fetor, cracking odorous gases such as ammonia and trimethylamine, hydrogen sulfide, hydrogen sulfide and methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide and styrene, sulfide H2S, VOC, molecular chain structure of benzene, toluene, xylene, organic or inorganic polymer odorous compounds molecular chain, under ultraviolet light irradiation, degraded into low molecular compounds, such as CO2, H2O, etc.

B,UV beam is used to crack the molecular bonds of bacteria in odorous gas, destroy the nucleic acid (DNA) of bacteria, and conduct oxidation reaction through ozone to achieve the purpose of deodorization and killing bacteria.

Ii. Use UV ultraviolet beam to decompose oxygen molecules in the air to produce free oxygen, namely reactive oxygen species. Due to the imbalance of positive and negative electrons carried by free oxygen, it needs to combine with oxygen molecules to produce ozone.

UV+O2→O-+O * (reactive oxygen species)O+O2→O3(ozone), it is well known that ozone has a strong oxidation effect on organic matters, and has an effect on odorous gases and other irritating odors.

C, nanometer TiO2 photocatalysis, and its mechanism in simple terms: nano TiO2 photocatalyst in specific wavelengths of light under the irradiation of excitation generated a hole "electronic" to (a) particles, this kind of "electronic a hole" in and around the water, oxygen, has the strong ability of oxidation - reduction, aldehydes, hydrocarbons and other pollutants in the air can be directly down into harmless tasteless substance, and destroy bacteria cell walls, kill bacteria and decompose the screen bacteria, so as to achieve the goal of eliminating air pollution.

D, "plasma waste gas treatment" series of products are the use of plasma to activate, ionize, pyrolysis waste gas in various components, thus a series of complex chemical reactions, will be harmful substances into clean air release to nature.

Five, the stench gas using collected after the exhaust equipment input to the purification equipment, purification equipment using UV ultraviolet light, ozone O3 and nanometer TiO2 photocatalysis technology combined to collaborative decomposition gas oxidation reaction, make the waste gas degradation into harmless, odorless compounds, water and carbon dioxide, and then through the exhaust pipe.
