Uv sterilizer technology and parameter

1, the mechanism of uv sterilizer

uv is a special form of matter run, is a kind of not connect particles. Every grain at 253. 7 nm ultraviolet photons with 4. 9 ev energy when bacteria, viruses, absorbs more than 3600 ~ 65000 ㎡ uw/c dose, the DNA of bacteria, virus ( DNA） And RNA ( RNA） Has strong destructive power, make the DNA received damage killing bacteria and microorganisms.

uv sterilizer sterilization principle is the use of ultraviolet lamp irradiation intensity, that is, the radiation intensity of ultraviolet germicidal lamps made by, and is inversely proportional to the distance according to disinfect. When water in ultraviolet light for a long time, so the sterilization effect is good, and the closer the light source, the sterilization effect is good, our company USES the Philip lamp, 30 w processing flow design of 1. 5 tons/hour, by analogy, if the flow is big, we use 145 w power tubes.

2, ultraviolet radiation sterilization efficiency

uv disinfection technology under the sufficient irradiation intensity, high efficiency of sterilization. The sterilization efficiency generally can reach more than 99%. And the sterilization time very short, only can be inactivated bacteria in 1 seconds.

traditional chemical disinfection methods to achieve such as chlorine, ozone generally to mix more than 6 minutes.

3, ultraviolet radiation sterilization and chlorine, ozone sterilization advantage

uv sterilization equipment without dead Angle, light condition is good, low energy consumption, equipment installation, convenient disassembly and no secondary pollution etc, uv sterilizer relative to chlorine disinfection, he has no need to add chemicals, no secondary pollution, no mixing equipment, greatly reduce equipment running cost, if they are drinking water, uv sterilizer security, not because of excessive and produce adverse effect to human body. Uv sterilizer relative ozone sterilizer, he has a small energy consumption, no big mixer, no fishy smell, not only in appearance, and reduce the operation cost. My company USES is Philip brand lamp, uv lamp theoretical service life of 8000 hours. Source:
