Photocatalytic Oxidation Reaction Mechanism ultraviolet photocatalytic reaction is very complicated. Conventional UV germicidal lamp lighting circuit when plugged in, because ultraviolet light disinfection high-impedance state, the power generated by the ballast and filament glow discharge, heat discharge bimetal thermal deformation and switched to the contact, the circuit current starts two cathode fluorescent lamp heating, a large number of electron emission, increase in mercury vapor lamp, complete the preheating of the fluorescent tube filament. Cathode heating, firing a large number of electrons in the mercury vapor lamp to increase the light hydrogen ion air purification device processing, the completion of the fluorescent tube circuit current starts to two bimetal thermal deformation of the fluorescent lamp is turned contacts Conventional UV After sterilization lighting circuits when power is turned on, because ultraviolet light disinfection high-impedance state, the power generated by the ballast and filament glow discharge optical hydrogen ion air purification device price, so that the heat discharge. Filament preheating. Hole has a strong ability of electrons entrapped after hit the water molecules, the water molecules are taken away electrons to form hydroxyl (-OH) light hydrogen ion air purification devices offer, hydroxy strong chemical activity, can destroy organics chemical bonds, to the desert of the decomposition of organic pollutants purposes. Some nanomaterials such as TiO2 composite photocatalyst powder, after ultraviolet irradiation, will produce 'electron - hole' right. Central air conditioning, air-purifying technology used broadly divided into the following categories, they have their own strengths, and with advances in technology continue to improve. 4. Nano photocatalyst nano technology is the use of titanium dioxide photocatalyst produce hydroxyl free radicals and reactive oxygen has an oxidation decomposition under UV irradiation, were potent bactericidal. Its combination of common and other formaldehyde, ammonia and benzene having a certain degradation. But only in the titanium dioxide particles as small as true nanoscale state, it can play an effective role. At this time the physical and chemical properties of titanium dioxide will change dramatically, the overall surface area will be massive increases in air can flow through the full contact with the surface of titanium dioxide, so as to achieve sterilization purposes.
