ULTRAVIOLET STERILIZATION AND DISINFECTION DEVICE AND CONFIGURATION METHOD THEREOF

摘要

Provided herein is an ultraviolet sterilization and disinfection apparatus. One or multiple low-pressure ultraviolet lamps are arranged within the ultraviolet sterilization and disinfection apparatus. A configuration method therefor is such that the inner diameters of the low-pressure ultraviolet lamps are Φ30-36 mm and the tube current density is: 0.250-0.800 A/cm2; alternatively the inner diameters are Φ26-30 mm and the tube current density is: 0.280-0.850 A/cm2; alternatively, the inner diameters are Φ20-26 mm and the tube current density is: 0.300-1.100 A/cm2; alternatively, the inner diameters are Φ15-20 mm and the tube current density is: 0.340-1.350 A/cm2. The method allows the ultraviolet dosage of the ultraviolet sterilization and disinfection apparatus to be increased, thus increasing efficiency in sterilization and disinfection.
