Principle of UV sterilization

External disinfection technology is the latest generation of disinfection technology that emerged in the late 1990s internationally. It integrates optics, microbiology, electronics, fluid mechanics, and aerodynamics, and has the characteristics of high efficiency, broad spectrum, low cost, long lifespan, large water volume, and no secondary pollution. It is internationally recognized as the mainstream consumer technology of the 21st century. Mainly used for sterilizing and disinfecting cooked food and water. Widely used in hospitals, food, herbal medicine, food and beverage processing and packaging equipment, health product factories, medical products, food factories, cosmetics factories, dairy factories, breweries, beverage factories, bakeries, and packaging product factories. The working principle of the equipment is that the ultraviolet sterilization band is mainly between

Between 200-300nm, the wavelength of 253.7nm has the strongest bactericidal ability. When various bacteria and viruses in water or air pass through the area irradiated with ultraviolet light (253.7nm wavelength), the ultraviolet light penetrates the cell membrane and nucleus of microorganisms, destroys the molecular bonds of nucleic acids (DNA or RNA), causing them to lose their replication ability or activity and die, thereby killing all bacteria and viruses without using any chemical drugs. Sterilization lamps do not need to be converted into visible light, and wavelengths of 100-200nm can effectively kill bacteria. This is because there is a pattern in the absorption spectrum of light waves by cells, with the maximum absorption occurring in the 100-200nm ultraviolet range. The absorbed ultraviolet light actually acts on the genetic material of cells, namely DNA, exerting a photochemical effect. The energy of ultraviolet photons is absorbed by the base pairs in DNA, causing genetic material to mutate, resulting in immediate death or inability to reproduce, achieving the purpose of sterilization.

UV disinfection technology has unparalleled sterilization efficiency compared to other technologies. The sterilization efficiency can reach 99% -99.9%. The table below shows that UV technology generally requires less than 1 second to kill several common bacteria and viruses. Traditional chemical disinfection methods such as chlorine gas and ozone generally require 20 minutes to 1 hour to achieve the sterilization effect of UV-C.

Characteristics and scope of use: The ultraviolet 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 problem of metal ion infection. The product structure is a closed container quartz sleeve type, with an electrical control device inside. The key ultraviolet lamp tube has a theoretical lifespan of up to 10000 hours, reaching the international advanced level. The product has a beautiful and elegant appearance, compact structure, and easy operation and maintenance. It is widely used in industrial and mining enterprises, residential life, hotels, government agencies, and schools; Field troops, food processing, pharmaceutical industry, high-purity water preparation, leisure tourism in public places or directly for drinking, and beverages or other industries that do not allow residual chlorine in water.

The advantages of ultraviolet disinfection technology

The disinfection effect of UV-C disinfection technology on bacteria, viruses, and other pathogens has been recognized worldwide, and it has unparalleled bactericidal efficiency compared to other technologies. The bactericidal effect of ultraviolet radiation on bacteria and viruses is generally within one second. For traditional chlorine and ozone methods, it usually takes 20 to 50 minutes to achieve the bactericidal effect of ultraviolet radiation. It has high efficiency and broad-spectrum sterilization, no secondary pollution, safe and reasonable design, and safe and reliable operation. Simple operation and maintenance, low cost. This device has a small footprint and no noise. Continuous large-scale sterilization. There are many advantages such as a wide range of application fields.

Pay attention to protection

Ultraviolet radiation has a powerful killing effect on bacteria and can also cause certain harm to the human body. The most vulnerable part of the human body is the cornea, so it is not advisable to look directly at a lit lamp at any time to avoid injury. If it is necessary to look, ordinary glass (wearing glasses) or transparent plastic sheets should be used as protective masks. Do not misuse quartz glass, as ordinary glass is almost completely impervious to ultraviolet radiation. Once injured, there is no need to panic. Facial burns will cause the epidermis to peel off after a few days and heal without treatment. Eye injuries can cause redness, swelling, tearing, and stinging, and take about three to four days to heal. Regardless, it is still recommended to seek medical attention immediately upon encountering injury

Maintenance and upkeep of ultraviolet sterilization machine

1. Regularly check to ensure the normal operation of the UV lamp.

After continuous use for 9000 hours or one year, the ultraviolet lamp tube should be replaced. When replacing a new lamp tube, first unplug the lamp tube power socket and take out the ultraviolet lamp tube. Be careful not to touch the quartz glass of the new lamp tube with your fingers, as stains can affect the strength of the light. At the same time, carefully place the lamp tube into the sterilization machine cavity.
