Universal UV Sterilizer Introduction


The disinfection principle of the universal ultraviolet sterilizer is to irradiate the objects that need to be sterilized by using the sun's rays with ultraviolet wavelengths between 200nm and 380nm. According to the characteristics of this sunlight, ultraviolet lamps made by special processes can be used for disinfection and sterilization. Universal ultraviolet sterilizers are used in many fields by using this principle.

The ultraviolet light disinfection mentioned in the general ultraviolet sterilizer water supply and drainage project actually refers to UVC disinfection. Universal ultraviolet light disinfection technology is based on modern epidemiology, medicine and photodynamics. It uses specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to irradiate flowing water to kill various bacteria, bacteria, parasites and algae in the water. And other pathogens are directly killed to achieve the purpose of disinfection. Recent studies have shown that short-wave UV rays (below 200 nanometers) in general-purpose UV sterilizers are highly efficient at decomposing organic molecules in water, especially low molecular weight pollutants.

Ultraviolet light with a wavelength below 200nm degrades TOC in two ways: (1) through direct photolysis, that is, the chemical bonds in organic matter are destroyed by ultraviolet energy; (2) through photolysis of water molecules to generate charged OH- radicals, Organic compounds are attacked by these free radicals. Ultraviolet sterilizer technology introduction: 1. Ultraviolet light is a kind of electromagnetic wave. When electrons in atoms jump from high energy level to low energy level, they will release excess energy as electromagnetic wave. The stronger the energy of the electromagnetic wave, the shorter the wavelength. The human naked eye can see the wavelength of 400nm-780nm. To the naked eye, the 400nm electromagnetic wave is displayed as blue, and the purple 780nm electromagnetic wave is displayed as orange and red.

Ultraviolet refers to electromagnetic waves with a wavelength shorter than 400nm. Because its spectrum is outside the purple region, it is called Ultraviolet (UV for short). 2. Ultraviolet rays usually refer to electromagnetic waves with a wavelength of 100-400nm. Human eyes cannot see ultraviolet rays. Ultraviolet rays with a wavelength of 100-400nm, according to their influence and function on the human body, are UV-A, UV-B, UV-C and V-UV.

UV-A refers to ultraviolet rays with a wavelength of 315-400nm. UV-A can make human skin produce melanin and darken the skin. UV-B is ultraviolet rays with a wavelength of 280-315nm. UV-B can cause cancer and wrinkle and age the skin. The wavelength of UV-C is 200-280nm, of which the 254nm band has the effect of sterilization and disinfection.

3. UV-C with a wavelength of 240-270nm can directly destroy the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of cells and viruses, causing the rapid death of microorganisms. 4. VUV185nm with a wavelength of 100-200nm can produce ozone, and ozone in the air or dissolved in water can destroy the cell wall of microorganisms by oxidation, causing the microorganisms to die immediately. Classification of general-purpose UV sterilizers: (1) According to the method of use, there are directly put the lamp in water, which is called immersion type; the ultraviolet lamp is used in a casing, called over-current type; the current mainstream products use over-current type Mode.

(2) According to the principle of action, there are disinfection, sterilization, photolysis and other photochemical reactions. (3) Divided by treatment objects, including, urban supply, drinking water treatment, pure water treatment, etc. (4) For high-end general-purpose ultraviolet sterilizer products, the disinfection method of the over-flow sterilization system is not only complicated, but also needs to be equipped with a complex control system, such as ultraviolet intensity detector, time accumulator, ultraviolet lamp monitoring, fault alarm, automatic sound and light alarm system.

(Optional) Ultraviolet sterilizers are widely used in food and beverage processing plants and independent water supply systems with various pipe diameters for disinfection and sterilization, and can also be used for ship and field water supply systems. According to the professional identification of the health and epidemic prevention department, Boying ultraviolet sterilizer can kill more than 99% of viruses and bacteria in water, which fully meets and complies with the relevant national water standards. Universal ultraviolet (UV) sterilizer technology was originally developed to ensure complete disinfection of town tap water.

Water is the most used substance, and disinfection technology has been adopted under the drive of more stringent standards and increasingly complex process requirements. The wide application of universal ultraviolet sterilizer technology has brought great economic benefits to many industries, and at the same time improved the operating efficiency of equipment.
