Manufacturer of medium voltage ultraviolet sterilizer Guanyu UV sterilizer Aike medium voltage ultraviolet sterilizer

Description :

　　The manufacturer of medium voltage ultraviolet sterilizers, Guanyu UV sterilizer, Aike medium voltage ultraviolet sterilizer, and low-pressure ultraviolet sterilizer differ in terms of sterilization intensity. Due to the higher photoelectric conversion rate of low-pressure ultraviolet lamps than medium voltage ultraviolet technology, low-pressure ultraviolet technology is often used in some industrial water treatment. Medium pressure ultraviolet radiation has its special advantages for disinfecting swimming pool water.

　　1) Low voltage ultraviolet lamps have high sterilization efficiency at a wavelength of 253.7mm, but only output a single frequency spectrum in a single straight line; The medium voltage ultraviolet lamp has a wide wavelength range and can kill many bacteria. For low load slightly polluted water bodies such as swimming pools, it is sufficient to meet the sterilization requirements

　　2) Low voltage ultraviolet lamps have little effect on degradation; The output wavelength range of medium voltage high-intensity ultraviolet lamps is wide (230-400m), containing wavelengths of 245mm, 297nm, and 340mm required for degradation. Photooxidation can effectively promote the decomposition of other organic compounds. The decomposition wavelengths are in the UVC, UVB, and UVA ranges, so medium voltage ultraviolet radiation has the ability to decompose and combine compounds. The medium pressure ultraviolet technology is far superior to the traditional low-pressure ultraviolet technology in terms of decomposition. The experiment used the same power (1200W) of medium and low-pressure ultraviolet to photodecompose in the swimming pool. The effective decomposition rate of medium pressure ultraviolet (mg/L level) can reach 74%, which is much higher than the degradation effect of low-pressure ultraviolet.

　　3) Effectively improve the ultraviolet penetration rate of swimming pool water quality. Penetration rate is one of the standards for evaluating water quality, and it is not exactly the same as turbidity. Turbidity is a characterization of suspended solids in water and does not represent dissolved substances in water. Ultraviolet radiation can oxidize organic matter in water and also destroy the structure of some substances that can cause water turbidity. Combined with filtration technology, it can improve the penetration rate of water quality. Medium pressure ultraviolet radiation can increase the penetration rate of water quality from 75% to over 97%

　　4) The Effect of Temperature on Sterilization Efficiency

　　The water temperature of a typical swimming pool is 26-28 ℃ or higher, which is higher than the evaluation temperature for the effectiveness of general disinfectants and disinfection methods (in general, tap water and sewage are lower than this temperature). The amount of ultraviolet radiation is affected by temperature, and the efficiency of low-pressure ultraviolet lamps is greatly affected by temperature, while the efficiency of medium pressure ultraviolet lamps is not affected by temperature.

　　Manufacturer of medium voltage ultraviolet sterilizer Guanyu UV sterilizer Aike medium voltage ultraviolet sterilizer Background of use: UV disinfection technology is a physical disinfection method with broad-spectrum sterilization ability, and it is also a disinfection method that does not produce disinfection by-products. At present, ultraviolet disinfection technology has developed into a safe, reliable, efficient and environmentally friendly disinfection technology, which has been widely used in various fields abroad. In China, ultraviolet disinfection technology is increasingly being emphasized and promoted due to its energy-saving and environmentally friendly characteristics, gradually replacing traditional chemical disinfection methods and becoming the mainstream water treatment and purification technology. With the gradual acceptance of ultraviolet disinfection technology by people and the continuous expansion of its scope of application, more requirements have been put forward for ultraviolet disinfection systems, not just limited to low-voltage lamps and low-power low flow water purification disinfection. In the market context of such usage requirements, high-power medium voltage ultraviolet disinfection systems have emerged.

　　Principle of medium voltage ultraviolet disinfection equipment: The principle of medium voltage ultraviolet disinfection equipment is basically the same as that of low-pressure ultraviolet disinfection equipment. The main difference lies in the fact that the ultraviolet lamp used belongs to the medium voltage standard. The ultraviolet lamp contains a small amount of mercury (liquid mercury or solid mercury), which appears in a vapor state under light irradiation. When the mercury evaporates, it is bombarded by photoelectrons to produce various wavelengths of ultraviolet light. The wavelength of the emitted ultraviolet light depends on the vacuum pressure inside the lamp. The low-pressure ultraviolet lamp is evacuated to a lower pressure (1-10 Pa) and can emit a single ultraviolet wavelength of 254 nanometers for sterilization. The medium voltage ultraviolet lamp is evacuated to a medium pressure (10-50 Pa) and can emit ultraviolet light with a wide spectrum of 254-265 nanometers. When the ultraviolet light is irradiated on microorganisms, the medium voltage ultraviolet sterilizer manufacturer Guanyu UV sterilizer Aike medium voltage ultraviolet sterilizer transfers and accumulates energy, The accumulation results in the collapse of microbial cell walls, killing microorganisms. When microorganisms absorb doses exceeding 3600-65000 uw/cm2, they have strong destructive power, causing them to lose their survival and reproductive ability, thus achieving the purpose of disinfection and sterilization. In summary, the principle of ultraviolet sterilization and disinfection is to use the irradiation intensity of the ultraviolet lamp tube, that is, the irradiation intensity emitted by the ultraviolet sterilization lamp is inversely proportional to the distance of the disinfected object being irradiated. The higher the irradiation intensity, the better the disinfection effect. When the irradiation intensity is constant, the longer the irradiation time of the disinfected object being irradiated and the closer it is to the sterilization lamp tube, the better the disinfection effect, and vice versa.
