Application Of Ultraviolet Disinfection Lamp in Water Treatment

1, Application in water treatment. There are two methods for water treatment with ultraviolet sterilization lamp: immersion type and overflow type. Putting the ultraviolet lamp directly into the water is called immersion type; The ultraviolet lamp is put into the casing for use, which is called over-current type. The over-current method is mainly adopted. The working principle of the overflow type equipment is that the water with a certain flow rate generated by the pressure of the water pump flows through the periphery of the quartz casing that can penetrate the ultraviolet light, and the ultraviolet light is generated by the ultraviolet lamp to disinfect and sterilize the water. The utility model is characterized in that the water flow velocity is very fast, and the time when the quartz jacket flows is generally no more than 1s, so the ultraviolet intensity of the sterilization lamp is required to be very high.

2, 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, chemical industry, medicine, health care, biology, beverage, agriculture and other fields. UV light source irradiates the surface of food and materials, which has rapid, efficient and pollution-free sterilization effect, so as to maintain the high quality of products. 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.

3, Application in medical and environmental sanitation. Using ultraviolet disinfection lamp to sterilize the air has a history of decades in hospitals, including static air direct irradiation method and mobile air disinfection method. The static air direct irradiation method adopts ultraviolet disinfection lamp for direct irradiation. Its disadvantage is that the place that cannot be irradiated cannot be disinfected, and people cannot be present during disinfection. Mobile air disinfection method adopts dynamic air disinfection machine, which can make up for the above two defects. The working principle of mobile air disinfector is to sterilize the air in the disinfector through indoor air circulation, so as to achieve the purpose of disinfecting the air in the whole room. The structure of this kind of disinfection machine mostly takes the shell of the indoor unit of household air conditioner. Mobile air disinfection machine has now developed into various disinfection equipment including sterilization, air conditioning and air purifier. The use is also popularized. The products used only in hospitals in the past have now moved to families, offices and announcement places. The functions are also diversified. Products used only for sterilization in the past can now be used for health care and prevention, and become health-related products.
