Abstract

The invention discloses a method for testing the effective output power of a sterilized ultraviolet lamp in a single-wavelength line shape. The method comprises the following steps: adjusting and mounting an ultraviolet lamp tube, a light shade, an ultraviolet actinograph (or an ultraviolet spectroradiometer) and an ultraviolet light intensity measuring platform in a laboratory with a temperature fluctuation range not exceeding 2 DEG C; preheating the ultraviolet lamp tube under the full-power operation of the ultraviolet lamp tube and respectively measuring ultraviolet light intensity E0 under the existence of the light shade and ultraviolet light intensity E1 under the absence of the light shade; and then, obtaining the effective output power P of the ultraviolet lamp tube according to a Gauss module equation. The invention has simple requirements for the laboratory conditions, needs simple instrument equipment, small investment, low detection cost and short time, has test results with good stability and high repeatability and can satisfy the requirements of related research departments and quality control departments for estimating the practical output power of the ultraviolet lamp tube. Enterprises for developing and producing ultraviolet sterilized equipment can also use the method to measure ultraviolet output to further simulate and optimize an ultraviolet reactor by using a hydromechanics calculating method.

Description

technical field [0001] The invention relates to a method for testing the effective output power of a single-wavelength linear sterilizing ultraviolet lamp. Background technique [0002] In the actual ultraviolet lamp sterilization (for water disinfection or air disinfection) system, it is very difficult to directly measure the effective output power of the ultraviolet lamp. Due to the temperature change and water transmittance change during the operation of the UV system, and the outside must be protected by a quartz sleeve, use different methods or measure in different laboratories, that is, use the same UV lamp And the combination of ballast, the result will be very different. Therefore, there is no widely recognized standard measurement method in China to measure the effective power output of single-wavelength linear germicidal UV lamps, which may lead to large differences in the measurement results of disinfection UV lamps. Therefore, it is urgent to study a measuremen...
