How High Is The Ultraviolet Disinfection Lamp From The Ground
Jan 11, 2022
The installation quantity of indoor suspended ultraviolet disinfection lamp shall be no less than 1.5W per cubic meter, and it is required to be evenly distributed, and the lifting height shall be 1.8 2.2m away from the ground, so that the human respiratory belt is in the effective irradiation range.
Continuous irradiation shall not be less than 30min. The ultraviolet radiation intensity is inversely proportional to the radiation distance, and the suspension is too high, which will affect the sterilization effect. If the object surface is disinfected, the distance between the lamp tube and the irradiated surface should be 1m, and the sterilization is effective.
The thickness of the water layer used for drinking water disinfection shall not exceed 2 cm. During disinfection, the ambient temperature shall be controlled at 20 degree 40 degree and the humidity shall be 40 percent 60 percent . Too high or too low temperature will affect the disinfection effect. The disinfection time can be extended appropriately. When the relative humidity is greater than 80 percent , the irradiation time can also be extended appropriately.
Is there a requirement for the installation height of ultraviolet disinfection lamp? Or what is its effective distance?
Ultraviolet disinfection usually uses the ultraviolet with the wavelength of 253.7nm, which is installed 1.8m to 2m high from the ground, and the sterilization effect is better within the irradiation range of 1.5 2m around.

Ultraviolet disinfection lamp is a lamp that uses ultraviolet rays to kill pathogenic microorganisms. All object surfaces, water and air polluted by pathogenic microorganisms can be disinfected by ultraviolet rays. The ultraviolet disinfection lamp used in China has high irradiation intensity and disinfection and sterilization effect at a longer distance. When used, it must be used in an unmanned state to avoid long-term exposure to human naked eyes and skin.

External sterilization is a traditional and effective disinfection method. It has been widely used in hospitals, food factories and water treatment. However, it is affected by many factors in the process of use, especially the low radiation intensity of lamp tube and improper application will affect the disinfection and sterilization effect. In order to ensure satisfactory disinfection effect, we have mainly implemented the following monitoring and management measures in use.
Radiation intensity of lamp tube ultraviolet radiation intensity is the basic factor affecting disinfection effect. According to the requirements of disinfection technical specifications, the radiation intensity of new ultraviolet lamp tube shall be greater than 100vw / cm2 (at a distance of 1m). The radiation intensity of lamp tube in use shall reach 70vw / cm2, which can be used temporarily, but the irradiation time must be extended.
Number of lamps installed
According to the provisions of Volume 2 (hospital disinfection specification) of the third edition of disinfection Technical Specifications issued by the Ministry of health, the installation quantity of indoor suspended ultraviolet disinfection lamps (30W ultraviolet lamps, with radiation intensity higher than 70 at 1m vertically) μ W / cm2) is not less than 1.5W per cubic meter on average, and it is required to be evenly distributed, and the lifting height is 1.8 2.2m from the ground, so that the human respiratory belt is in the effective irradiation range.
