(1) in the application of surface sterilization, UV surface sterilization device is widely used in food, electronics, semiconductors, liquid crystal display, plasma TV, crystal vibrator, precision devices, chemical, medical, health, biological, beverage, agriculture and other fields. UV light source irradiation food, materials and other surfaces, with fast, efficient, pollution-free sterilization effect, so as to maintain the high quality of products. Compared with the traditional sterilization method, surface sterilization has the characteristics of fast sterilization, continuous processing and batch processing, simple operation, environmental protection without secondary pollution.
(2) Application in water treatment. The use of uv sterilization lamp for water treatment has immersion and flow two methods, directly put the UV lamp into the water, known as immersion; The ultraviolet lamp is used in the casing, which is called overflow. The main method is overflow. The working principle of the overflow equipment is that the water flow at a certain velocity of pressure generated by the water pump passes through the quartz sleeve outside the ultraviolet ray, and the ultraviolet ray produced by the ultraviolet lamp disinfect and sterilize the water. Its characteristic is that the water flow rate is very fast, generally in the quartz coat flow is not more than 1s, so the ultraviolet intensity of the sterilization lamp is very high, generally requires the surface intensity of more than 3000UW /cm2.
(3) Application in medical environment health. The use of ultraviolet disinfection lamp to sterilize the air has been in the hospital for decades, there are static air direct irradiation method and flow air disinfection method. Static air direct illumination method uses ultraviolet disinfection lamp direct illuminate, its shortcoming is the place that irradiation cannot disinfect, the person cannot be present when disinfect. Flow air disinfection method uses dynamic air disinfection machine, this kind of disinfection machine just can make up for the above two defects. The working principle of mobile air disinfection machine is to sterilize the air in the disinfection machine through indoor air circulation, so as to achieve the purpose of air disinfection in the whole room. The structure of this kind of disinfection machine is mostly taken from the shell of the indoor machine of household air conditioning. Flow air disinfection machine, has developed into a variety of disinfection equipment including sterilization air conditioning, air purifier and so on. The use of products used only in hospitals has also become popular, and they have moved to homes, offices and public places. The function is also diversified, the products used only for sterilization can be used for health care, prevention, become health related products.
