UV photolysis principle briefly: in the wavelength range of 170nm-184.9nm (704 kj / mol - 647 kj / mol) high-energy ultraviolet light, while oxygen in the air is cleaved, and then combined to produce ozone; on the other hand the stench bond breaking gas, and make it a free state of atoms or groups; at the same time participate in the ozone generated during the reaction, so malodorous gases eventually cleaved, oxidized simple stable compounds, such as CO2, H2O, N2 and the like. A performance review, efficiency in addition to the stench: efficient removal of volatile organic compounds of major pollutants (VOC), inorganic, hydrogen sulfide, ammonia, mercaptans, as well as a variety of bad odor, deodorization efficiency up to 99% above, deodorization effect is much higher than the national emission standards for odor pollutants enacted in 1993 (GB14554-93). Second, the need to add any substance: only need to set the appropriate exhaust pipes and exhaust power, malodorous gases through decomposition purification deodorization this equipment without the addition of any substance involved in chemical reactions. And third, adaptability: can adapt to high concentrations of air volume, deodorizing malodorous gaseous substances of different purification process, 24 hours a day for work, stable and reliable. Fourth, low operating costs: this device without any mechanical movement, no noise, no special management and maintenance, just to make regular inspections of the equipment low energy consumption (per handle 1000 m3 / h and consumes only about 0.2 degrees energy), the device is extremely low wind resistance <100pa, can save a lot of exhaust power consumption. Five, without any pretreatment: malodorous gases without the need for special pre-treatment, such as heating, humidification and other equipment working environment centigrade temperature between -30 ℃ -95 ℃, humidity at 30% -98%, PH value of 2- It can work normally between 13. Sixth, equipment, small footprint, light weight: suitable for a compact layout, small venues and other special conditions, equipment area <1 m2 / processing 10000m3 / h air flow. Seven high-quality imported materials: fire, explosion, high corrosion resistance, performance security and stability, made of stainless steel, equipment service life of more than fifteen years. Eight, environmental protection high-tech patent products: using the most advanced technology concepts, through expert engineering and technical staff and our long-term repeated tests, developed and worked out, with high-tech environmental purification products are completely independent intellectual property rights, can be completely decomposed stench gas is toxic and harmful substances, and can achieve the perfect deodorizing effect, the malodorous gases decomposed, can fully meet the sound emissions, no secondary pollution, while achieving effective disinfection and sterilization effect.
