UV photolysis air purifier uses a special high-energy and high-ozone UV ultraviolet beam to irradiate malodorous gas, cracking malodorous gas such as: ammonia, trimethyl, amine, hydrogen sulfide, methyl sulfide, methyl mercaptan, methyl sulfide, ether, dimethyl, Disulfide, carbon disulfide and styrene, sulfide H2S, VOCs, benzene, toluene, xylene molecular bonds, make free pollutant molecules and ozone oxidatively combine into small molecules harmless or low-harm compounds, such as CO2 , H2O, etc.
The use of high-energy and high-ozone UV ultraviolet light beams decomposes oxygen molecules in the air to produce free oxygen, that is, active oxygen. Because the free oxygen carries an imbalance of positive and negative electrons, it needs to combine with oxygen molecules to produce ozone. UV+O2→O-+O* (active oxygen) O+O2→O3 (ozone), as we all know, ozone has a strong oxidizing effect on organic matter, and has a strong removal effect on malodorous gases and other irritating odors.
After the malodorous gas is input to the purification equipment by the exhaust equipment, the purification equipment uses high-energy UV ultraviolet light beams and ozone to synergistically decompose and oxidize the malodorous gases, so that the malodorous substances are degraded and converted into low molecular compounds, water and carbon dioxide, and then passed through the exhaust The air duct is discharged outside.
 
Use high-energy UV light beams to crack the molecular bonds of bacteria in the malodorous gas, destroy the nucleic acid (DNA) of the bacteria, and then oxidize through ozone to completely achieve the purpose of deodorization and killing bacteria.
 
UV photolysis air purifier is a perfect combination of plasma decomposition exhaust gas purifier + UV light deodorizing exhaust gas purifier. It combines the advantages of plasma exhaust gas purifier and ultraviolet photocatalyst deodorizing exhaust gas purifier. It uses the combination of plasma decomposition technology and UV ultraviolet photolysis technology to efficiently purify exhaust gas and odor!
 
Next, let’s talk about the UV sensor that can be used in UV photolysis air purifiers. The editor recommends a UV sensor imported from abroad-GUVC-T21GH. This sensor has a chip size of 0.4mm, a TO 5 package, and a small size. Single power supply voltage operation, with high sensitivity and good sun blindness. Widely used in: UV intensity detection and control, UV index detection, outdoor UV index detection equipment, etc., can also be used for ultraviolet disinfection and UV curing, used to monitor ultraviolet intensity, UV flame detectors, etc.
 
Performance characteristics of UV photolysis air purifier:
 
1. Efficient deodorization: It can efficiently remove volatile organic compounds (VOC), inorganics, hydrogen sulfide, ammonia, mercaptans and other major pollutants, as well as various odors, and the deodorization efficiency can reach more than 99%. The effect greatly exceeds the national emission standards for odor pollutants issued in 1993 (GB14554-93).
 
2. No need to add any substance: only need to set up the corresponding exhaust pipe and exhaust power, so that the malodorous gas can be deodorized, decomposed and purified through this equipment, without adding any substance to participate in the chemical reaction.
 
3. Strong adaptability: It can adapt to the deodorization and purification treatment of high concentration, large air volume, and different malodorous gas substances. It can work continuously for 24 hours a day, and the operation is stable and reliable.
 
4. Low operating cost: This equipment has no mechanical action, no noise, no special management and routine maintenance, only regular inspections, low energy consumption of this equipment, (each processing 1000 cubic meters / hour, only power consumption is about 0.2 degrees Electricity), the wind resistance of the equipment is extremely low <50pa, which can save a lot of exhaust power energy consumption.
 
5. No pretreatment is required: no special pretreatment is required for malodorous gas, such as heating, humidification, etc. The working environment temperature of the equipment is between -30°C and 95°C, the humidity is between 30% and 98%, and the PH value is between 2 and 2 13 can work normally.
 
6. The equipment occupies a small area and light weight: it is suitable for special conditions such as compact layout and small space. The equipment occupies an area of ​​<1 square meters/handling 10000m3/h air volume.
 
7. Manufacture of high-quality imported materials: high fire-proof, explosion-proof and anti-corrosion performance, safe and stable equipment performance, stainless steel material, equipment service life of more than 15 years.
 
8. Environmental protection high-tech patented products: Adopting the most advanced technology concepts in the world, through long-term repeated tests by experts and our company’s engineers and technicians, we have developed a high-tech environmental protection purification product with completely independent intellectual property rights, which can completely decompose the odor Poisonous and harmful substances in the gas can achieve a perfect deodorization effect. The decomposed malodorous gas can be completely harmless and discharged without secondary pollution. At the same time, it can achieve efficient disinfection and sterilization.
