Description

Technical Field

[0001] The invention belongs to the technical field of ozone concentration detection, and in particular relates to an ozone concentration detection device for ultrapure water. Background Art

[0002] Ultrapure water, also known as UP water, refers to water with a resistivity of 18MΩ*cm (25°C). This water contains almost no impurities except water molecules, and no bacteria, viruses, chlorinated dioxins and other organic substances, and of course no mineral trace elements needed by the human body. In other words, it is water that has almost all atoms except oxygen and hydrogen removed.

[0003] Studies have shown that ozone has a maximum absorption coefficient only for ultraviolet rays with a wavelength of 253.7nm. At this wavelength, ultraviolet rays will be attenuated when passing through ozone, which conforms to the Lamport-Beer law. The principle of ultraviolet absorption method is mainly used in ozone detection of ultrapure water. Ultraviolet rays are generated by a stable ultraviolet light source, and ultraviolet rays of other wavelengths are filtered out through a light wave filter, allowing only ultraviolet rays with a wavelength of 253.7nm to pass.

[0004] However, when detecting the ozone concentration in ultrapure water, in order to improve the detection accuracy, detection is generally performed through two ultraviolet light source nodes, which is prone to inconsistent light intensity, resulting in detection errors, and the sampling tube is easily contaminated by the external environment during storage, resulting in errors in the sampling test results.

[0057] The working principle of the ozone concentration detection device for ultrapure water provided by the present invention is as follows:

[0058] The first step: when in use, connect the second external threaded connector 18 to the ultrapure water storage tank, start the liquid pump 13, draw the ultrapure water sample into the detection box 4 through the sampling hose 17 and the liquid suction tube 14, start the ultraviolet lamp board assembly 7, and the ultraviolet light emitted by the ultraviolet lamp board assembly 7 is irradiated on the filter 9, and other wavelengths of ultraviolet light are filtered out by the filter 9, and only ultraviolet light with a wavelength of 253.7nm is allowed to pass through, and then the ultraviolet light with a wavelength of 253.7nm is irradiated on the polarizing plate 8, and the polarizing plate 8 only allows the light perpendicular to the polarizing plate 8 to pass, so that the light passes through the top light-transmitting plate 5 and irradiates the ultrapure water in the detection box 4, and then passes through the bottom light-transmitting plate 6 and irradiates the first photoelectric sensor 10 and the second photoelectric sensor 11 respectively.
