UV sterilization lamps

sterilization lamps Introduction:

Ultraviolet disinfection lamps are also called ultraviolet sterilization lamps and ultraviolet fluorescent lamps. A lamp for sterilization and disinfection using ultraviolet sterilization.

The ultraviolet disinfection lamp radiates ultraviolet rays with a wavelength of 253.7nm. The ultraviolet ray has the strongest sterilization ability, and can be used for disinfection and sterilization of water, air, clothing, etc.

The specifications of ultraviolet disinfection lamps commonly used in farms are 15W, 20W, 30W and 40W, and the use voltage is 220V. It is mainly used for disinfection and sterilization of personnel, and is generally installed in disinfection dressing rooms, veterinary rooms and laboratory rooms. The bacteria and viruses carried on the clothes can be killed by the ultraviolet disinfection lamp for about 5 minutes. It can also be used for air disinfection of laboratories and operating rooms that require clean air.

Irradiation can kill bacteria in the air for about 30 minutes. UV disinfection lamps are mainly divided into high pressure, medium pressure and low pressure. Disinfection applications are mainly based on low pressure. According to national standards, the average life expectancy is 8000 hours. Some excellent products have reached 13,000 hours of life.

UV sterilization lamps

Ultraviolet lamps, also known as ultraviolet disinfection lamps, use ultraviolet light emitted by mercury lamps to achieve sterilization and disinfection functions. Ultraviolet disinfection technology has unmatched sterilization efficiency of other technologies, and the sterilization efficiency can reach 99% ~ 99.9%.

The scientific principle of ultraviolet disinfection: it mainly acts on the DNA of microorganisms, destroys the DNA structure, and makes it lose the functions of reproduction and self-replication to achieve the purpose of disinfection and disinfection. Ultraviolet sterilization has the advantages of being colorless, odorless, and without chemical substances.

But if there is no protective measures, it is easy to cause huge harm to the human body. If the bare skin is irradiated by this kind of ultraviolet light, it will be red, swollen, itchy, and desquamated in the light ones; in severe cases, it may even cause cancer and skin tumors. At the same time, it is also an “invisible killer” of the eye, causing inflammation of the conjunctiva and cornea. Long-term exposure may cause cataracts.

sterilization lamps Application:

In the application of surface sterilization, UV surface sterilization devices are widely used in food, electronics, semiconductors, liquid crystal displays, plasma TVs, crystal vibrators, precision devices, chemicals, medicine, health care, biology, beverages, agriculture and other fields.

The UV light source illuminates the surface of food, materials, etc., which has a fast, efficient and pollution-free sterilization effect, thereby maintaining the high quality of the product. Compared with traditional sterilization methods, surface sterilization has the characteristics of fast sterilization speed, continuous treatment and batch treatment, simple operation, environmental protection and no secondary pollution.

Application in medical environment sanitation. The use of ultraviolet disinfection lamps to sterilize air has been in hospitals for decades. There are direct static air irradiation methods and flowing air disinfection methods.

The static air direct irradiation method uses ultraviolet disinfection lamps to directly irradiate. Its disadvantage is that it cannot be sterilized in places where it cannot be irradiated, and people cannot be present during disinfection. The mobile air disinfection method uses a dynamic air disinfection machine, which can make up for the above two defects.

The working principle of the mobile air disinfection machine is to sterilize the air passing through the disinfection machine through indoor air circulation, so as to achieve the purpose of disinfecting the entire indoor air. The structure of this type of sterilization machine mostly uses the housing of the indoor unit of the household air conditioner.

The mobile air disinfection machine has been developed into various disinfection equipment including sterilization air conditioners and air purifiers. The use has also been popularized. Products that were used only in hospitals in the past have moved to homes, offices, and public announcements.

The functions are also diversified, and the products that were used only for sterilization in the past can be used for health care and prevention, and become health-related products.

sterilization lamps Kind:

Ordinary straight tube hot cathode low pressure mercury ultraviolet disinfection lamp. The lamp tube is made of quartz glass or other glass with high ultraviolet transmittance, and the power is 40W, 30W, 20W, 15W, etc. The intensity of 253.7mm ultraviolet radiation (measured at a distance of 1m without a reflector) is required for the new lamp shipped from the factory: power> 30W lamp, intensity ≥ 90Wcm2, (≥100W / cm2 in the hospital infection management specification issued in 2000), Lamps with power> 20W, intensity ≥60μW / cm2; lamps with power 15W, intensity ≥20W / cm2; because this lamp radiates 253.7mm ultraviolet rays, it also radiates a part of 184.9nm ultraviolet rays, so it can produce ozone.

High-intensity ultraviolet disinfection lamp. The intensity of 253.7mm ultraviolet radiation (measured at a vertical distance of 1m from the center of the lamp tube) is required to be a power 30W lamp,> 170μW / cm2; 11W lamp,> 40μW / cm2.

Ultraviolet air sterilizer. Made with low ozone ultraviolet germicidal lamp, it can be used for indoor air disinfection under manned conditions.
