Ultraviolet sterilizer

Detail:

The working principle of the equipment is: the ultraviolet wave band is mainly between

In the range of 200-300nm, the bactericidal ability of 253.7nm is the strongest. When all kinds of 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, destroy the molecular bond of nucleic acid (DNA or RNA), make it  or activity and die, so as to kill all bacterial viruses without using any chemical drugs. The sterilization lamp does not need to be converted into visible light, and the wavelength of 100-200nm can play a good role in sterilization. This is because there is a rule in the absorption spectrum of the light wave of the cell. The ultraviolet light at 100-200nm has the largest absorption. The absorbed ultraviolet light actually acts on the genetic material of the cell, namely DNA, which plays a role in photochemistry. The energy of ultraviolet photons is DNA The absorption of the base pairs in can cause the variation of the genetic material, and make the bacteria die or can't reproduce the offspring immediately, so as to achieve the goal of sterilization.

Sterilization efficiency UV disinfection technology has a sterilization efficiency that other technologies can't match. The bactericidal efficiency is 99% - 99.9%. The following table lists the sterilization time of UV technology for several common bacterial viruses, which generally takes less than 1 second. However, it usually takes 20 minutes to 1 hour for traditional chemical disinfection methods such as chlorine and ozone to achieve the sterilization effect of ultraviolet C.

Features and scope of use: UV sterilizer has the characteristics of uniform water flow, no dead angle, good light radiation conditions, complete sterilization, low energy consumption, flexible and convenient installation, the main material is stainless steel, no metal ion infection problem, the product structure is quartz sleeve type sealed vessel, with electrical control device inside. Among them, the key ultraviolet lamp has a theoretical life of up to 10000 hours, reaching the international advanced level. The product has beautiful appearance, compact structure and convenient operation and maintenance. It is widely used in industrial and mining enterprises, residents' life, hotels, government schools, field troops, food processing, pharmaceutical industry, high-purity water preparation, public places or direct drinking leisure tourism and beverage or other industries without residual chlorine in the water.

Application:

Widely used in hospitals, food, Chinese herbal medicine or Spices, food and beverage processing and packaging equipment, health products factory, medical products, food factory, cosmetics factory, dairy factory, brewery, beverage factory, bakery and packaging products factory, etc.

Advantages of UV disinfection technology:

The disinfection effect of UV-C on bacteria, virus and other pathogens has been recognized all over the world, and it has incomparable sterilization efficiency. The bactericidal effect of ultraviolet on bacteria and virus is generally within one second. For the traditional chlorine and ozone methods, it usually takes 20 to 50 minutes to achieve the sterilization effect of ultraviolet. The utility model has the advantages of high efficiency sterilization, wide spectrum, no secondary pollution, safe and reasonable design, safe and reliable operation. Simple operation and maintenance, low cost. The equipment covers a small area without noise. Continuous mass sterilization. Many advantages, such as wide application fields.
