Microwave electrodeless ultraviolet sterilization equipment Once 1 falls below the required intensity, it should be replaced in time. The service life of the ultraviolet disinfection lamp is reduced from the intensity of the new lamp to 70 μ At the moment of W/cm2 (power ≥ 30W), or when the intensity drops to 70% of the original new lamp intensity (power<30W), it should not be less than 1000h. The UV lamp manufacturer should provide the actual service life.
When killing common bacterial breeding bodies, the illumination dose should reach 10000 μ W.s/cm2; 100 000 for killing bacterial spores μ W.s/cm2; The resistance of the virus to ultraviolet ray is between the bacterial multiplication body and the spore; The resistance of fungal spores is stronger than that of bacterial spores, sometimes it needs to be illuminated to 600000 μ W. S/cm2, but the resistance of common pathogenic fungi to ultraviolet light is weaker than that of bacterial spores.
When the disinfection policy microorganism is unknown, the illumination dose should not be less than 100000 μ W. S/cm2, the irradiation dose is the product of the irradiation intensity of the used ultraviolet lamp at the surface of the object to be illuminated and the illumination time. Therefore, according to the irradiation intensity of the ultraviolet light source, the time to be illuminated can be calculated, for example, when the irradiation intensity is 70 μ The W/cm2 ultraviolet surface sterilizer shines on the surface of the article at close intervals, and the selected irradiation dose is 100 000 μ W. S/cm2.
