Introduction of ultraviolet sterilizer and comparison with traditional sterilizer

2023/03/28

Mechanism of stainless steel ultraviolet sterilizer Ultraviolet light is a special form of material operation, and it is a flow of unconnected particles. Each ultraviolet photon with a wavelength of 253.7nm has an energy of 4.9eV. When bacteria and viruses absorb a dose of more than 3600~65000uW/c㎡, it has a strong effect on deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of bacteria and viruses. Destructive force, which damages DNA and leads to the death of bacteria and microorganisms. The sterilizing principle of ultraviolet sterilizer is to use the radiation intensity of the ultraviolet lamp tube, that is, the radiation intensity emitted by the ultraviolet germicidal lamp, which is inversely proportional to the distance of the irradiated object to be sterilized.

That is, when the water stays in the ultraviolet light for a long time, the sterilization effect is better, and the closer it is to the light source, the better the sterilization effect. Our company uses Philips lamps, and the designed 30W treatment flow rate is 1.5 tons/hour. By analogy, if the flow rate is large, We use 145W high-power lamps. Ultraviolet sterilization efficiency Under sufficient irradiation intensity, ultraviolet disinfection technology has extremely high sterilization efficiency. The sterilization efficiency can generally reach more than 99%.

And the sterilization time is extremely short, bacteria can only be inactivated in 1 second. Traditional chlorine, ozone and other chemical disinfection methods generally require mixing for more than 6 minutes. Stainless steel ultraviolet sterilization and chlorine gas, ozone sterilization advantages Ultraviolet sterilizer has the characteristics of no dead angle, good light irradiation conditions, low energy consumption, flexible and convenient equipment installation and disassembly, and no secondary pollution. Compared with chlorine gas sterilization, ultraviolet sterilizer has no need to add Chemical agents, no secondary pollution, no mixing equipment, greatly reducing equipment operating costs, if it is drinking water, ultraviolet sterilizers are safe, and will not have adverse effects on the human body due to excessive amounts of agents.

Compared with the ozone sterilizer, the ultraviolet sterilizer has the advantages of low energy consumption, no large mixer, no fishy smell, etc. It not only looks good, but also reduces operating costs, so it is widely used in the water treatment and filtration industry. Our company uses Philips brand lamps, and the theoretical life of the ultraviolet lamps is as long as 8,000 hours. Poolking is the best swimming pool equipment manufacturer and supplier in China. Poolking exists to provide the highest quality swimming pool equipment while offering competitive pricing..
