Chengdu medium voltage ultraviolet sterilizer

Description :

　　The principle of Chengdu 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 the dosage is used, it has strong destructive power. The Chengdu medium pressure ultraviolet sterilizer causes microorganisms to lose their survival and reproductive ability, thereby 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.
