Beijing medium voltage ultraviolet sterilizer manufacturer

Description :

　　The difference between manufacturers of medium voltage ultraviolet disinfectors and low-pressure ultraviolet disinfectors in Beijing lies in the sterilization intensity. Due to the higher photoelectric conversion rate of low-pressure ultraviolet lamps compared to 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.

　　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), which can emit a single ultraviolet wavelength of 254 nanometers for sterilization. The medium pressure ultraviolet lamp is evacuated to a medium pressure (10-50 Pa), which can emit ultraviolet light with a wide spectrum of 254-265 nanometers. When the ultraviolet light is irradiated to microorganisms, energy transfer and accumulation occur, resulting in the collapse of the microbial cell wall and the killing of microorganisms. When microorganisms absorb more than 3600-65000 Pa, the accumulation results in the destruction of microorganisms. uw/cm2 When administered, it has a strong destructive power, causing microorganisms 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.

　　In the design of medium voltage ultraviolet disinfection equipment, in addition to the selection of core products, the integration of equipment is very important. The surface temperature of the lamp wall of medium voltage lamps can reach up to 600-800oC, and the selection and configuration of the sleeve have a significant impact on the lifespan and effectiveness of the lamp tube; Due to the high temperature of the lamp tube, extremely high requirements are placed on the sealing design and cooling system of the system; The control system for ballasts and lamp dimming, as well as other control systems, will be crucial for the stable operation of the system. Whether another water treatment and disinfection system can become a reliable sterilization and inactivation system requires professional UV dose calculation and verification. Whether the equipment is equipped with a cleaning system, temperature sensing monitoring, ultraviolet radiation measurement monitoring, PLC integration, and so on.
