I produced the UV photolysis efficient exhaust gas cleaning equipment, used by the US imported specialty lighting launch tube, the UV light emitting tube can be converted into electrical energy efficient 185nm wavelength UV light. At the same power consumption, a substantial increase in the decomposition efficiency and avoid unnecessary energy loss. Technical principles I. The products use a special high-energy beam of high ozone UV irradiation malodorous gases, molecular bond cleavage of malodorous gases that was free state of a single molecule is incorporated into a small molecule ozone oxidation harmless or less harmful compounds, such as CO2 , H2O, etc. Second, the use of high energy ultraviolet beam UV ozone decomposing oxygen molecules in the air to produce free oxygen, i.e., reactive oxygen species, due to the free oxygen labile to be combined with oxygen molecules, and produce ozone. UV + O2 → O- + O * (reactive oxygen species) O + O2 → O3 (ozone), known to ozone oxidation of organic matter has a strong effect on the odorous gases and other irritating odor have an immediate effect cleared. Third, the stench of exhaust gas utilization equipment entered into after this purification equipment, decontamination equipment and the use of high-energy beam of ultraviolet UV ozone decomposition of malodorous gases collaborative oxidation degradation malodorous gaseous substances converted into low molecular weight compounds, water and carbon dioxide, and then exhausted to the outside through the exhaust pipe. Fourth, the use of high-energy UV beam malodorous gas molecules bond cleavage of bacteria, destruction of bacterial nucleic acid (DNA), and then an oxidation reaction by ozone, to completely kill bacteria and to achieve the purpose of deodorization. An overview of product performance, efficiency besides stench: efficient removal of volatile organic compounds of major pollutants (VOC), inorganics, etc., as well as a variety of odor, deodorization efficiency up to 99%, much higher than the national deodorizing effect in 1993 stench pollutant emission standards promulgated (GB14554-93). Second, without adding any substance: only need to set the appropriate exhaust pipes and exhaust power, malodorous gases through decomposition purification deodorization this equipment without adding any substance involved in chemical reactions. And third, adaptability: can adapt to high concentrations of atmospheric volume, deodorizing malodorous gaseous substances of different purification treatment, 24 hours a day of continuous work, stable and reliable. Fourth, low running 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 process 1000 cubic meters / hour, consumes only about 0.2 degrees power), the device is extremely low drag <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 Celsius ambient temperature between -30 ℃ -95 ℃, humidity at 30% -98%, PH value in 2- can work between 13. Six, small equipment footprint, light weight: Suitable for 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, safe and stable equipment performance, the use of stainless steel, equipment service life of more than fifteen years. Eight, environmental protection high-tech patent products: using the most advanced technology concepts, by experts and our engineering and technical personnel long-term repeated tests, developed out with high-tech environmental purification products completely independent intellectual property rights, can be completely decomposed stench gas, toxic and hazardous substances, and can achieve the perfect deodorizing effect, the stench of decomposition gases can be completely harmless emissions, no secondary pollution, while achieving efficient disinfection effect.
