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 irradiates the surface of food, materials, etc., and has a fast, efficient and pollution-free sterilization effect, thereby maintaining the high quality of the product. Compared with the traditional sterilization method, the ultraviolet lamp has the characteristics of fast sterilization speed, continuous processing and batch processing, simple operation, environmental protection and no secondary pollution.
There are two methods for water treatment with UV disinfection lamps: immersion and overflow. Putting the UV lamp directly into the water is called immersion; using the UV lamp in a casing is called overflow. Mainly used is the over-flow method. The working principle of the over-flow equipment is that the water flow with a certain flow rate generated by the pressure of the water pump flows through the periphery of the quartz sleeve that can transmit ultraviolet rays, and the ultraviolet rays are generated by the ultraviolet lamp to disinfect and sterilize the water. Its characteristic is that the water flow rate is very fast, and generally the time that it flows through the quartz jacket is no more than 1s. Therefore, the ultraviolet intensity of the disinfection lamp is required to be very high, and the surface intensity is generally required to exceed 30000uw/cm2.
The use of ultraviolet lamps to sterilize air has been used in hospitals for decades. There are static air direct irradiation method and flowing air disinfection method. The static air direct irradiation method uses ultraviolet lamps for disinfection to directly irradiate them. The disadvantage is that the places that cannot be irradiated cannot be disinfected, and people cannot be present during disinfection. The flow air disinfection method uses a dynamic air disinfection machine, which can just make up for the above two shortcomings. The working principle of the mobile air sterilizer is to sterilize the air passing through the sterilizer through indoor air circulation, so as to achieve the purpose of sterilizing the entire indoor air. The structure of this type of sterilizer mostly adopts the shell of the indoor unit of the household air conditioner. The mobile air disinfection machine has developed into various disinfection equipment including sterilization air conditioners and air purifiers. The use is also popularized. Products that were only used in hospitals in the past have moved to homes, offices, and public announcement places. The functions are also diversified. Products that were only used for sterilization in the past can be used for health care and prevention, and become health-related products.
Dairies, breweries and bakeries in the food processing industry. It is a necessary product for sterilization and disinfection of air, instrument industry, drinking water, and equipment. According to different usage needs, there are different ways to use ultraviolet lamps for disinfection, choose disinfection lamps of different powers, use them scientifically, and achieve disinfection methods.
