Problems solved by technology

However, this method has certain inherent defects: in order to prolong the ultraviolet irradiation time, it is usually necessary to increase the area or volume of the disinfection area irradiated by the ultraviolet source, so as to achieve the purpose of complete disinfection, so this method is not practical
Using the existing technology to increase the UV dose and improve the efficiency of one-time sterilization, on the one hand, the device is bulky, expensive, and inconvenient to place; Efficiency is greatly reduced, and system energy consumption is high

Abstract

The invention discloses an ultraviolet sterilization disinfection method and an ultraviolet sterilization disinfection device. One or more low-pressure ultraviolet lamps are arranged in the ultraviolet sterilization disinfection device, the inner diameter of each low-pressure ultraviolet lamp is phi 30-36mm, and the tube current density of each low-pressure ultraviolet lamp is 0.250-0.800A / cm<2>; or the inner diameter of each low-pressure ultraviolet lamp is phi 26-30mm, and the tube current density of each low-pressure ultraviolet lamp is 0.280-0.850A / cm<2>; or the inner diameter of each low-pressure ultraviolet lamp is phi 20-26mm, and the tube current density of each low-pressure ultraviolet lamp is 0.300-1.100A / cm<2>; or the inner diameter of each low-pressure ultraviolet lamp is phi 15-20mm, and the tube current density of each low-pressure ultraviolet lamp is 0.340-1.350A / cm<2>. By the adoption of the ultraviolet sterilization disinfection method and the ultraviolet sterilization disinfection device, the ultraviolet dosage of the ultraviolet sterilization disinfection device can be improved, and the sterilization disinfection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an ultraviolet sterilization device and a setting method thereof. Background technique [0002] Ultraviolet disinfection technology is widely used in various sterilization and disinfection fields. The ultraviolet source can be ultraviolet LED or ultraviolet mercury vapor discharge lamp. In the field of air purification, harmful substances in the air can also be killed by ultraviolet disinfection to achieve the purpose of improving air quality. Ultraviolet rays can destroy the DNA and RNA of microorganisms, and have a killing effect on microorganisms. Ultraviolet rays have a decomposing effect on some harmful organic substances, and the combination of ozone and hydrogen peroxide has a better effect of oxidative decomposition. No matter what kind of ultraviolet light source, its ultraviolet dose determines the effect of ultraviolet sterilization and disinfection, namely:...
