Outside line disinfection technology is the latest generation of international disinfection technology emerging in the late 1990s. It integrates optics, microbiology, electronics, fluid mechanics, and aerodynamics. It has the characteristics of high efficiency, broad spectrum, low cost, long life, large water volume, and no secondary pollution. It is internationally recognized mainstream consumer technology in the 21st century. Mainly used to sterilize cooked food and water. It is widely used in hospitals, food, Chinese herbal medicine, food and beverage processing and packaging equipment, health care products factories, medical products, food factories, cosmetics factories, dairy factories, wineries, beverage factories, bakeries and packaging products factories. The working principle of the device is that the ultraviolet sterilization band is mainly between 200-300nm, and the sterilization ability with the wavelength of 253.7nm is the strongest. When various bacterial viruses in water or air pass through the ultraviolet (253.7nm wavelength) irradiation area, ultraviolet rays penetrate the cell membrane and nucleus of microorganisms, destroying molecular bonds of nucleic acid (DNA or RNA), causing them to lose their replication ability or activity and die. To kill all bacterial viruses without using any chemicals. The germicidal lamp does not need to be converted into visible light. The wavelength of 100-200nm can play a good bactericidal effect. This is because the cell has a regular absorption spectrum of light waves. Ultraviolet rays at 100-200nm have maximum absorption,the absorbed ultraviolet light actually acts on the genetic material of the cell, that is, DNA, and it plays a photochemical role. The energy of the ultraviolet photons is absorbed by the base pairs in the DNA, causing the genetic material to mutate, causing the bacteria to die immediately or fail to reproduce to achieve the purpose of sterilization.
Ultraviolet disinfection technology has unparalleled sterilization efficiency. Sterilization efficiency can reach 99% -99.9%. Ultraviolet technology generally takes less than 1 second to sterilize several common bacterial viruses.However, it takes 20 minutes to 1 hour for the traditional chlorine and ozone chemical disinfection methods to achieve the UV C sterilization effect.
Using Characteristics and Scope
UV sterilizer has the characteristics of uniform water flow, no dead corners, good light irradiation conditions, thorough sterilization, low energy consumption, flexible and convenient installation, etc.The main material is stainless steel, and there is no metal ion infection problem.Product structure is sealed container quartz sleeve type.Built-in electrical control device.The key UV lamp management life is as long as 10,000 hours, reaching the international advanced level. The product has a beautiful appearance, compact structure, convenient operation and maintenance, and is widely used in industrial and mining enterprises, residential life, restaurants, hotels, institutions and schools; field forces, food processing, pharmaceutical industry, high-purity water preparation, public places or leisure tourism directly for drinking. Beverages and other industries residual chlorine is not allowed.
Advantages of UV Disinfection Technology
Ultraviolet C disinfection technology has been recognized on worldwide for the disinfection of bacterial viruses and other pathogens, It has unparalleled sterilization efficiency compared with other technologies. The germicidal effect of ultraviolet rays on bacteria and viruses is generally within one second. For traditional chlorine and ozone methods, it takes 20 to 50 minutes to achieve the germicidal effect of ultraviolet light. It has a broad spectrum of efficient sterilization, no secondary pollution, safe and reasonable design, safe and reliable operation. Simple maintenance and low cost. This equipment occupies a small area and has no noise. Continuous mass sterilization. Wide application fields and many other advantages.
Pay attention to protection
Ultraviolet rays have a powerful lethality to bacteria, and also have a certain degree of damage to the human body. The most vulnerable part of the human body is the cornea of the eyes. Therefore, you must not look directly at the lighted tube at any time to avoid injury. When it is necessary to watch, use ordinary glass (wearing glasses) or transparent plastic sheet as a protective face shield. Do not use quartz glass by mistake, because ordinary glass is almost completely impermeable to ultraviolet rays. Once injured, don't panic and burn your face. After a few days, the epidermis comes off and heals without treatment. Eye injuries can be red, swollen, tearful, and tingling, and it will take about three or four days to heal.However, in case of injury, it is still recommended to seek medical treatment immediately.
Maintenance and maintenance of UV sterilizer
1. Regularly check to ensure the normal operation of the UV lamp.
2. After continuous use for 9000 hours or one year, the UV lamp should be replaced. When replacing a new lamp, first unplug the lamp power socket and take out the ultraviolet lamp. Be careful not to touch the quartz glass of the new lamp with your fingers, as the stain will affect the intensity of the light. At the same time, carefully put the lamp into the interior of the sterilizer.
