Abstract

The invention discloses a method for measuring the emission power of an ultraviolet lamp in water. The method comprises the following steps of: placing an ultraviolet lamp arranged in a quartz sleevein water, and placing a chemical exposure meter on a perpendicular bisector of the ultraviolet lamp; recording absorbance values of the ultraviolet lamp collected by the chemical exposure meter beforeand after irradiation by controlling positions of the chemical exposure meter at different distances from the ultraviolet lamp; calculating a radiation illuminance curve of the ultraviolet lamp withthe change of distance by a system; fitting the radiation illuminance curve with a radiation illuminance curve calculated by a radiation illuminance calculation formula by the system to obtain the emission power of the ultraviolet lamp. The invention also discloses a system for measuring the emission power of the ultraviolet lamp in water. The method and the system provided by the invention can measure the actual ultraviolet emission power of the combination of the underwater ultraviolet lamp and the quartz sleeve, the cost is low, the operation method is simple and the measurement can be carried out in a conventional laboratory, so that the method and the system can be widely applied to the field of ultraviolet lamps.

Description

technical field [0001] The invention relates to the field of ultraviolet lamps, and is specifically applied to measuring the actual ultraviolet emission power of ultraviolet lamps and quartz sleeves combined in water and other media. Background technique [0002] Currently there is no method for measuring the UV output power of UV lamps in other media such as underwater. For water disinfection, UV lamps are placed underwater. [0003] When UV lamps are used for water disinfection applications, they are placed in a quartz sleeve and then placed in the water body. The current method of measuring underwater ultraviolet emission power can only measure its relative value, which is used for comparison between different lamps. For reactor or process design using ultraviolet light for water disinfection, it is necessary to know the absolute value of the actual ultraviolet emission power of the combination of ultraviolet lamp and quartz sleeve, but there is no corresponding method ...
