Beijing ultraviolet sterilizer factory direct sales

  Overview of ultraviolet sterilizer: the ultraviolet sterilizer is a device that uses the ultraviolet mercury lamp as the light source and the 253
7nm ultraviolet radiation radiated during the discharge of mercury vapor in the lamp tube as the main spectral line to disinfect drinking water (hereinafter referred to as the sterilizer)
It destroys and changes the DNA structure of microorganisms through the irradiation of ultraviolet light, so that bacteria die immediately or can not reproduce offspring, so as to achieve the purpose of sterilization
All life is based on DNA and RNA as the basis of reproduction and survival
During cell reproduction, the long chain in DNA is opened
After opening, the a unit on each long chain will find the T unit to combine
Each long chain can replicate the same chain as the other long chain just separated, restore the original complete DNA before division, and become the basis of newborn cells
Ultraviolet light with a wavelength of 240nm ~ 270nm can break the ability of DNA to produce protein and replication
After the DNA and RNA of cells or viruses are destroyed, their ability to produce proteins and reproduce have been lost
Because the general life cycle of bacteria and viruses is very short, bacteria and viruses that cannot reproduce will die quickly
Ultraviolet can be divided into UV-A (320-400nm), UV-B (275-320nm), UV-C (200-275nm) and vacuum ultraviolet according to the difference of its biological function
The UV-C part of ultraviolet is actually used in water treatment
In this band, the ultraviolet with the highest sterilization efficiency is near 260nm
Advantages of ultraviolet disinfection: 1
High efficiency sterilization: the sterilization of bacteria and viruses by ultraviolet rays can reach a sterilization rate of 99% - 99
9% in one to two seconds
2
High efficiency and broad spectrum sterilization: the broad spectrum of ultraviolet sterilization is the highest
It can kill almost all bacteria and viruses with high efficiency
3
No secondary pollution: ultraviolet sterilization does not add any chemical agents, so it will not cause secondary pollution to the water body and the surrounding environment and will not change any components in the water
4
Safe and reliable operation: traditional disinfection technologies such as chloride or ozone, the disinfectant itself belongs to *, flammable substances, while the ultraviolet disinfection system does not have such potential safety hazards
5
Low operation and maintenance costs: UV sterilization equipment occupies a small area and has simple requirements for structures, so the total investment is less and the operation cost is low
At the level of 1000 tons of water treatment capacity, its cost is only 1 / 2 of chlorine disinfection
Instructions for the use of ultraviolet sterilizer: 1
It is strictly prohibited to start the ultraviolet sterilizer frequently, especially in a short time, so as to ensure the service life of the ultraviolet lamp
2
Regular cleaning of ultraviolet sterilizer: according to the water quality, the ultraviolet lamp tube and quartz glass sleeve need to be cleaned regularly
Wipe the lamp tube with alcohol cotton ball or gauze to remove the dirt on the quartz glass sleeve and wipe it clean, so as not to affect the ultraviolet transmittance and sterilization effect
3
When replacing the lamp tube, first pull out the power socket of the lamp tube, pull out the lamp tube, then carefully insert the wiped new lamp tube into the sterilizer, install the sealing ring, check whether there is water leakage, and then plug in the power supply
Be careful not to touch the quartz glass of the new lamp tube with your fingers, otherwise the sterilization effect will be affected by stains
4
Prevention of ultraviolet radiation: ultraviolet radiation has strong lethality to bacteria and certain harm to the human body
When starting the disinfection lamp, avoid direct irradiation to the human body
If necessary, use protective glasses
Do not directly face the light source with your eyes to avoid burning the eye mask
Common sense of life: 178
When you put on makeup, put the wet cosmetics into the fridge
After a few minutes, put the cold sponge on the skin with good foundation
You will feel that the skin is extra cool and the make-up is very fresh
