If it is drinking water, the ultraviolet sterilizer is safe and will not adversely affect the human body due to the excessive amount of medicine Compared with the ozone sterilizer the ultraviolet sterilizer has the advantages of low energy consumption, no large mixer, no fishy smell, etc., which not only has a good look and feel but also reduces operating costs.

The working principle of UV sterilizer

The working principle of UV sterilizer is to use ultraviolet light to sterilize and sterilize. Ultraviolet light is an invisible light wave that exists outside the violet end of the spectrum, so it is called ultraviolet light. Ultraviolet light is one of the electromagnetic waves that come from solar radiation and is generally divided into the following four categories by wavelength.

It is a special form of matter functioning, a flow of unconnected particles. When the ultraviolet rays are irradiated on the microorganisms, energy transfer and accumulation will occur, and the accumulation will lead to the inactivation of the microorganisms, so as to achieve the purpose of disinfection. When bacteria and viruses absorb a dose of more than 3600~65000uW/c㎡, they have strong destructive power to the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of bacteria and viruses, which will make bacteria and viruses lose their viability and reproduction. force. , and then destroy it to achieve the effect of disinfection and sterilization. On the one hand, UVC can mutate nucleic acids, preventing its replication, transcriptional block, and protein synthesis; on the other hand, the production of free radicals can cause photoionization, which leads to cell death.

The sterilization efficiency of UV sterilizer

Ultraviolet sterilizer has other technologies with unparalleled sterilization efficiency. The sterilization efficiency can reach 99%-99.9%. And the sterilization time is very short, the bacteria can only be inactivated within 1 second. Traditional chemical disinfection methods such as chlorine and ozone generally take 20 minutes to 1 hour to achieve the sterilization effect of UVC.

Types of UV Sterilizers

Pipeline UV Sterilizer

Pipeline UV sterilizer, also known as overflow UV sterilizer, is connected to the water pipe, turn on the power supply UV lamp to work, the water flows through the light irradiation area, and automatically sterilizes the water body to achieve the required water quality. It can make the turbulent flow of the treated water, make the water contact with ultraviolet rays more fully and uniformly, and achieve a more efficient sterilization effect. Spectrum sterilization, so that the treated water can achieve sterilization effect in a very short time.

Medium pressure UV sterilizer

Medium pressure UV sterilizers actually refer to the gas pressure inside the lamp. The main advance is the ability to create lamps that produce higher output power than low pressure lamps, thus providing greater disinfection power. Medium-pressure technology uses fewer lamps, has a smaller footprint, is compact, and tends to provide higher levels of inactivation than low-pressure UV at the same dose.

Open Channel UV Sterilizer

The open channel UV sterilizer sterilizes the water flowing through the channel by emitting short-wave ultraviolet radiation with a wavelength of 253.7nm from the UV lamp installed in the slotted channel, thus solving the problem of excessive bacteria in the treated sewage and making the bacteria in the discharged water. Meet and exceed the relevant national emission standards. Mainly used for disinfection of municipal sewage, domestic sewage, hospital sewage, industrial sewage and reclaimed water reuse.

How to install the UV sterilizer?

1. The UV sterilizer is suitable for indoor safety equipment, and outdoor safety equipment must be equipped with rain-proof and dust-proof facilities.

2. The built-in quartz shell and UV lamp tube of the UV sterilizer are fragile items, and should be handled with care during transportation, installed and used safely, avoiding collisions and violent vibrations.

3. The UV sterilizer should be installed horizontally and safely, not vertically, the barrel should not be subject to external pressure, and the quartz sleeve should not be contacted at the inlet and outlet.

4. The ultraviolet sterilizer should be safely installed at the outlet of the water tank or pool. If the water pressure is high, it should be safely installed in the low-pressure area before the pump inlet or with a pressure reducing valve.

5. The UV sterilizer is safely installed at both ends of the equipment, leaving a space of ≥1m and 0.5m (1.6m and 0.5m for high-power models) to facilitate the replacement of lamps and electric control maintenance boxes. There is no less than 0.5m of space.

6. The two ends of the water inlet and outlet of the UV sterilizer can choose one as the water inlet and the other as the water outlet, and the customer can follow up with their own convenience.

7. The ultraviolet sterilizer should be equipped with bypass pipeline and stop valve during safe installation to facilitate maintenance.

8. Before the water operation and debugging, the construction residual debris in the pipeline should be rinsed clean by bypass, and the inlet and outlet valves of the ultraviolet sterilizer should be opened after the water quality is clean.

9. After the UV sterilizer is safely installed, test the water first, and check for water leakage before turning on the power. Wait until all the lamps work normally for 3-5 minutes (the lamp indicator shows that the lamps are normal), and then boil the water. Open the water valve first, then open the water valve, and the equipment starts to work.

Advantages of using a UV sterilizer

1. Ultraviolet sterilizer High-efficiency sterilization: UVC can sterilize bacteria and viruses. Generally, a sterilization rate of 99%-99.9% can be achieved in one to two seconds.

2. Ultraviolet sterilizer has high-efficiency broad-spectrum sterilization: UVC has the highest broad-spectrum sterilization, which can kill almost all bacteria and viruses with high efficiency.

3. The ultraviolet sterilizer has no secondary pollution: ultraviolet sterilization does not add any chemical substances, so it will not cause secondary pollution to the water body and the surrounding environment. Do not alter any composition of the water.

4. UV sterilizer is safe and reliable: traditional disinfection techniques such as chlorine or ozone, the disinfectant itself is a highly toxic and flammable substance. The UV disinfection system does not have such a safety hazard.
