How high is the UV disinfection lamp from the ground?

The number of indoor suspended ultraviolet disinfection lamps installed is an average of not less than 1.5W per cubic meter, and it is required to be evenly distributed and the lifting height is 1.8-2.2m away from the ground, so that the human breathing belt is in the effective irradiation range.

Continuous irradiation is not less than 30 minutes, the intensity of ultraviolet radiation is inversely proportional to the radiation distance, and the suspension is too high, which will affect the sterilization effect. If it is to disinfect the surface of the object, the distance between the lamp tube and the irradiated surface should be 1m for the disinfection to be effective.

Used for drinking water disinfection. The thickness of the water layer is not more than 2 cm. During disinfection, the ambient temperature is controlled at 20℃～40℃, and the humidity is 40%～60%. Too high or too low temperature will affect the disinfection effect, and the disinfection time can be appropriately extended. When the humidity is greater than 80%, the irradiation time should be extended appropriately.

Is there a height requirement for the UV disinfection lamp? Or how long is its effective distance?

Ultraviolet disinfection usually uses ultraviolet rays with a wavelength of 253.7nm, installed at a height of 1.8 meters to 2 meters from the ground, and has a better sterilization effect within an irradiation range of 1.5 to 2 meters.

Ultraviolet disinfection lamps are lamps that use ultraviolet rays to kill pathogenic microorganisms. All surfaces, water and air contaminated by pathogenic microorganisms can be disinfected by ultraviolet rays. The ultraviolet disinfection lamp used in China has high radiation intensity and longer distance disinfection and sterilization effect. When using it, it must be used in an unmanned state to avoid long-term exposure to human eyes and skin.

Is there a height requirement for the UV disinfection lamp? Or how long is its effective distance?

The number of indoor suspended ultraviolet disinfection lamps installed is an average of not less than 1.5W per cubic meter, and it is required to be evenly distributed and the lifting height is 1.8-2.2m away from the ground, so that the human breathing belt is in the effective irradiation range.

Is there any installation height requirement for the UV disinfection lamp?

Ultraviolet disinfection usually uses ultraviolet light with a wavelength of 253.7nm.

The installation is 1.8 meters to 2 meters high from the ground, and the sterilization effect is better within the irradiation range of 1.2 meters.

External sterilization is a traditional and effective disinfection method. It has been widely used in hospitals, food factories, water treatment, etc., but it is affected by many factors during use, especially the low radiation intensity of the lamp and improper application. Disinfection and sterilization effect. In order to ensure a satisfactory disinfection effect, we mainly implemented the following monitoring and management measures during use.

The radiation intensity of the lamp Ultraviolet radiation intensity is the most basic factor that affects the disinfection effect. According to the requirements of the "Disinfection Technical Specification", the radiation intensity of the new ultraviolet lamp should be greater than 100VW/cm2 (at a distance of 1m) to be qualified and in use The minimum radiation intensity of the lamp should reach 70VW/cm2, which can be used temporarily, but the irradiation time must be extended.

Number of lamps installed

According to the “Disinfection Technical Specification” issued by the Ministry of Health, the third edition of the second sub-volume (Hospital Disinfection Specification), the number of indoor suspended ultraviolet disinfection lamps installed (30W ultraviolet lamps, the radiation intensity at a vertical 1m is higher than 70μW/cm2) The average is not less than 1.5W per cubic meter, and it is required to be evenly distributed, and the lifting height is 1.8-2.2m away from the ground, so that the human breathing belt is in the effective irradiation range.
