Principle of Ultraviolet Sterilization
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 lose the ability of replication 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.
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 absorbed by the base pairs in DNA can cause the variation of the genetic material, and make the bacteria die or unable to reproduce the offspring immediately, so as to achieve the goal of sterilization.
Sterilization Efficiency
UV disinfection technology has a sterilization efficiency that other technologies cannot match.
The bactericidal efficiency is 99% - 99.9%.
Sterilization of several common bacterial viruses generally takes less than 1 second.
Traditional chemical disinfection methods such as chlorine and ozone usually take 20 minutes to 1 hour 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, and flexible and convenient installation.
The main material is stainless steel, with no metal ion infection problem.
The product structure is a quartz sleeve type sealed vessel, with an electrical control device inside.
The key ultraviolet lamp has a long theoretical life, 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.
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.
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 and wide application fields.
Safety and Protection
Ultraviolet has strong killing power to bacteria, and it also has certain harm to the human body; the most vulnerable part of the human body is the cornea of the eye.
It is not allowed to look directly at the lighted lamp tube at any time to avoid injury.
In case it is necessary to look, ordinary glass (with glasses) or transparent plastic sheet shall be used as the protective mask.
Never use quartz glass by mistake, because ordinary glass can hardly penetrate ultraviolet rays.
Once injured, do not panic; with facial burns, the epidermis falls off a few days later and heals without cure.
Eye injury can be red, swollen, tearful and tingling, taking about three or four days to recover.
In any case, it is recommended to see a doctor immediately in case of injury.
Maintenance of UV Sterilizer
Check regularly to ensure the normal operation of the UV lamp.
After 9000 hours or one year of continuous use, the ultraviolet lamp should be replaced.
When replacing a new lamp, first unplug the power socket of the lamp and take out the ultraviolet lamp.
Pay attention not to touch the quartz glass of the new lamp with your fingers, because the stain will affect the intensity of the light, and carefully put the lamp into the chamber of the sterilizer.
