Photocatalytic oxidation

　　I Working Principle

　　1. Photocatalytic oxidation occurs under the action of visible light. The photocatalytic oxidation reaction takes semiconductor and air as catalyst and light as energy to degrade organic matter into CO2 and H2O, kill viruses and bacteria, and remove peculiar smells. The company USES artificial ultraviolet light wave as energy source, with nano TiO2 catalytic net with the strongest activity and highest reaction efficiency as catalyst, to achieve relatively ideal purification effect in air purification and disinfection and sterilization, and completely improve air quality and freshness.

　　2, in the semiconductor photocatalytic oxidation reaction, nanometer TiO2 catalytic net absorption of light energy and produce electronic jump leap, holes, electrons and holes by leaps forward powerful combination to produce pair, general and surface adsorption of H20, O2 reaction to generate oxidizing very live wave of oxyhydrogen free radical (OH -) and super oxide free radical (O2 -, O -) ions. To air a variety of harmful gas such as formaldehyde, benzene, ammonia and TVOC other direct oxidation of organic matter into H20 and CO2 and inorganic small molecules, and kill all kinds of transmitted virus bacteria in the air, sterilization rate of more than 98%, harmful ingredients and virus after bacterial oxidation also there will be no odor and harmful gas, so as to achieve clean air power, because the antioxidant is H2O and CO2 of the air, so it won't create any secondary pollution.

　　Ii. Technical Features

　　1. Efficient odor removal: it can effectively remove volatile organic compounds (VOC), inorganic substances, hydrogen sulfide, ammonia gas, mercaptan and other major pollutants, as well as various foul smells. The purification and deodorization efficiency can reach more than 99%.

　　2. No need to add any substance: it only needs to set the corresponding exhaust pipe and exhaust power to decompose and purify the industrial waste gas through the equipment, and no need to add any substance to participate in the chemical reaction. .

　　3, strong adaptability: can adapt to high concentration, large gas volume, different industrial waste gas material purification treatment, can work 24 hours a day, stable and reliable operation.

　　4. Low operating cost: the equipment has no mechanical action, no noise, no special person for management and daily maintenance, and only needs regular inspection. The equipment has low energy consumption (every 1000 cubic meters/hour, only about 0.2 degree of electricity consumption), and extremely low wind resistance < 50PA, which can save a lot of power consumption of exhaust power.

　　5, no pretreatment: industrial waste gas does not need special pretreatment, such as heating, humidifying, etc., the operating environment temperature of the equipment is between -30℃-95℃, humidity is between 30%-98%, PH value is between 4-10 can work normally.

　　6. Small floor space and light dead weight: it is suitable for special conditions such as compact layout and narrow space. The floor space of the equipment is less than 1 square meter/handling 10,000m3 /h air volume.

　　7. High quality material manufacturing: high fire and corrosion resistance, stable performance and long service life.

　　Iii. Scope of Application
