Solar UV disinfection lamp and its application

2020-05-06 16:33:07

Solar ultraviolet lamps, also called 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 sterilization and disinfection. Ultraviolet sterilization has the advantages of being colorless, odorless, and without chemical substances. But if there are 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, and long-term exposure may cause cataracts

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 high sterilization speed, continuous treatment and batch treatment, simple operation, environmental protection, and no secondary pollution.

Application in water treatment. There are two methods of using ultraviolet sterilization lamps for water treatment: immersion type and over-flow type. Putting the UV lamp directly into the water is called immersion type; when the UV lamp is put into the casing, it is called an overflow type. The main method 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 penetrate the ultraviolet, and the ultraviolet light is generated by the ultraviolet lamp to disinfect and sterilize the water. Its characteristic is that the water flow velocity is very fast, generally, it is not more than 1s when the quartz jacket flows through, so the ultraviolet intensity of the germicidal lamp is very high, and the surface intensity is generally more than 30000uw / cm2.
