The role of ultraviolet air disinfection machine

ZHONGWU ultraviolet air disinfection machine is a machine that disinfects the air through the principles of filtration, purification and sterilization. In addition to killing bacteria, viruses, molds, spores and other so-called sterilization and disinfection, some models can also remove formaldehyde, phenol and other organic pollutants in the indoor air, and can also kill or filter pollen and other allergens. At the same time, it can effectively remove the smoke and smoke smell generated by smoking, the bad smell of the bathroom, and the body odor of people. The disinfection effect is reliable, and the disinfection can be carried out under the condition of human activity, so as to realize the coexistence of man and machine.

The principle of ultraviolet air disinfection machine

To achieve the inactivation of bacteria in the air, the closer the UV lamp tube is to the object being disinfected, the more and faster the bacteria will be killed. In the range of ultraviolet radiation, the bacterial mortality rate can be guaranteed to be 100%, and no bacteria can escape.

The principle of sterilization is to irradiate bacteria, viruses and other microorganisms by ultraviolet rays to destroy the structure of DNA (deoxyribonucleic acid) in its body, causing it to immediately die or lose its ability to reproduce. Quartz UV lamps have advantages, so how to identify true and false. The ultraviolet sterilization ability of different wavelength bands is different. Only short-wave ultraviolet (200-300nm) can kill bacteria. Among them, the sterilization ability is the strongest in the range of 250-270nm. The cost and performance of ultraviolet lamps made of different materials are also different. Really high-intensity, long-life ultraviolet lamps must be made of quartz glass. This lamp is also called quartz germicidal lamp. It is divided into two types: high ozone type and low ozone type. Generally, high ozone type is used in disinfection cabinets, which is also Compared with other ultraviolet lamps, quartz ultraviolet lamps have a remarkable feature. In addition, it produces high ultraviolet intensity, which is more than times that of high boron lamps, and has a long lifetime of ultraviolet radiation intensity. The most reliable resolution method is to measure with a 254 nm probe of an ultraviolet irradiance meter. At the same power, the highest ultraviolet intensity at 254 nm is the quartz ultraviolet lamp. The second is the high-boron glass ultraviolet lamp. The ultraviolet light intensity of the high-boron glass lamp is easily attenuated. After it is turned on for hundreds of hours, the ultraviolet light intensity drops sharply to 50%-70% of the initial. In the user's hands, although the lamp is still on, it may no longer work. The degree of light attenuation of quartz glass is much smaller than that of high boron lamps. No matter what kind of glass is used for the fluorescent tube, it is impossible to emit short-wave ultraviolet rays, and it is even less likely to produce ozone, because the spectral line converted by the fluorescent powder has a shortest wavelength near 300 nm, which is in the disinfection cabinet What you can often see is the mosquito killer lamp, which can only produce 365nm spectral line and a part of blue light. Its function is not disinfection except attracting mosquitoes.

Precautions for ultraviolet air disinfection machine

Whether it is used for static disinfection or dynamic continuous disinfection, it is required to close doors and windows.

It is strictly forbidden to cover or block the air inlet and outlet of the disinfection machine.

The power socket must use a three-core socket with a safety ground.

Water is strictly prohibited inside the machine. When cleaning the machine with a damp cloth, you must first cut off the power.

In order to achieve the disinfection effect, it should not be used in excess volume.

Regularly check the working status of the machine, if abnormalities are found, they should be repaired immediately, and electrical failures should be handled by professional technicians.

Maintenance of ultraviolet air disinfection machine

The instrument is managed by a dedicated person and keeps 24h power-on standby to avoid frequent startup damage.

Filter maintenance: Check the filter regularly. If you find too much dust in the filter, you should clean or replace the filter with clean water in time. When replacing, open the filter cover, remove the filter net from the machine, replace it with a new filter, and then reinstall the filter on the machine.

Maintenance of ultraviolet lamp: The intensity of ultraviolet radiation will affect the air disinfection effect. Therefore, use ethanol cotton balls to wipe the ultraviolet lamp at least once a month to ensure that the radiation intensity of the ultraviolet lamp is not affected by dust.

Maintenance of negative oxygen ion generator: Due to the dust-reducing effect of negative oxygen ions, after long-term use, a large amount of dust will be deposited near the generator outlet casing, so it should be removed regularly. When cleaning, you should first cut off the power and wipe with a soft dry cloth or a little medical ethanol. Note: Do not rinse with water. The human body sensor probe and display screen cannot be wiped with any detergent, ethanol, etc., but can only be wiped gently with a damp cloth.
