Description

Technical Field

[0001] The invention relates to the technical field of material detection, in particular to an ozone concentration detection device. Background Art

[0002] Ozone concentration detection equipment has important applications in environmental monitoring. It can monitor the ozone concentration in the atmospheric environment, provide a scientific basis for government departments to formulate relevant policies, and effectively reduce the impact of ozone pollution on human health. In the industrial field, ozone concentration detection equipment is used to detect the ozone concentration at the outlet of the ozone generator to ensure that the ozone concentration in the production process is controlled within the preset range. This is crucial for applications such as drinking water disinfection, sewage purification, air sterilization and purification in sterile places, and food storage and preservation.

[0003] The ozone concentration detection equipment in the prior art directly injects ozone gas into the interior of the detection container and completes the detection process with the help of ultraviolet spectrophotometry. However, since ozone gas is prone to decomposition when it is close to the surface of an object and due to the diffusion phenomenon, there will be slight differences in the ozone concentration in different areas. Conventional ozone concentration detection equipment will also cause errors in the measurement results due to this problem. On the other hand, conventional ozone concentration detection equipment can only perform targeted detection on ozone gas or liquid containing ozone. If the concentration of ozone gas is detected after the liquid is detected, the detection error will be further increased due to the interference of humidity. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: an ozone concentration detection device, comprising a detection device body, the detection device body comprising a detection tank 1, a driving mechanism 5, a feeding mechanism 6 and a sample storage assembly 7, a support frame 3 is welded on the side of the detection tank 1, a base 2 is welded on the bottom of the support frame 3, a top plate 4 is welded on the top of the support frame 3, the driving mechanism 5 passes through the middle position of the top plate 4, and the end of the driving mechanism 5 is embedded in the interior of the detection tank 1, a feeding mechanism 6 is inserted at the bottom of the detection tank 1, and the bottom of the feeding mechanism 6 is welded to the surface of the base 2, the base 2 A sample storage assembly 7 is welded to the side, and the sample storage assembly 7 is used to store the ozone gas sample to be tested. The feeding mechanism 6 is used to draw the ozone gas inside the sample storage assembly 7 into the interior of the detection tank 1. An ultraviolet light source 14 and a photoelectric sensor 15 are installed at the end of the driving mechanism 5, and the outer ends of the ultraviolet light source 14 and the photoelectric sensor 15 are both against the inner wall of the detection tank 1. The ozone concentration detection equipment can detect and process the current concentration of the ozone gas that has been delivered to the sample storage assembly 7, and can also be used to detect the ozone concentration in a liquid containing ozone.

[0029] The present invention is based on the fact that ozone molecules have the maximum absorption characteristics for ultraviolet light of a specific wavelength. Ozone has the maximum absorption coefficient for ultraviolet light with a wavelength of 254nm. When ultraviolet light passes through the ozone layer, the intensity of the light will decay. Therefore, when a stable ultraviolet light source 14 is used to generate ultraviolet light, ultraviolet light of other wavelengths is filtered out through the light wave filter provided in the light source, and only ultraviolet light with a wavelength of 254nm is allowed to pass. When this part of ultraviolet light passes through the ozone layer, the intensity of the light will decay, and the degree of decay is proportional to the concentration of ozone. The current concentration of ozone can be determined by measuring the change in light intensity through the photoelectric sensor 15. Based on the above principle, when it is necessary to detect the current concentration of ozone gas inside the sample storage component 7, the feeding mechanism 6 at the bottom is directly controlled to move downward, so that the ozone gas inside the sample storage component 7 can be extracted and transported to the inside of the detection tank 1. At this time, the drawn-in ozone gas can be directly detected and processed by the ultraviolet light source 14 and the photoelectric sensor 15 at the bottom of the driving mechanism 5, and the driving mechanism 5 is started to control the ultraviolet light source 14 and the photoelectric sensor 15 to rotate, so that the ozone gas on different paths in the detection interlayer 25 can be efficiently detected multiple times, so as to obtain the final average value. If the ozone concentration in the liquid containing ozone is to be detected, the feeding mechanism 6 is directly moved downward, the liquid to be tested is injected, and then moved upward, so that the ozone concentration in the liquid can be directly detected with the help of the ultraviolet light source 14 and the photoelectric sensor 15.

[0030] In this embodiment, a top barrier sleeve 22 and a bottom barrier sleeve 21 are welded inside the detection tank 1, and a detection interlayer 25 is provided between the top barrier sleeve 22 and the bottom barrier sleeve 21. A fixing plate 23 is integrally formed on the side of the top barrier sleeve 22, and the fixing plate 23 is welded and fixed to the inner wall of the detection tank 1. A rotation gap 20 is provided between the top barrier sleeve 22, the bottom barrier sleeve 21 and the inner wall of the detection tank 1, and an arc plate 26 is welded on the inner wall of the rotation gap 20. The bottom of the rotation gap 20 is in a closed state, and both ends of the top barrier sleeve 22 and the bottom barrier sleeve 21 are in an open state. The feeding mechanism 6 penetrates upward from the bottom of the bottom barrier sleeve 21. There are two arc plates 26, and the two arc plates 26 are symmetrically arranged on both sides of the detection interlayer 25. While the driving mechanism 5 controls the rotation of the ultraviolet light source 14 and the photoelectric sensor 15, the arc plate 26 provided inside the detection tank 1 can also push the ultraviolet light source 14 and the photoelectric sensor 15. Therefore, after rotating to a fixed position, the distance between the ultraviolet light source 14 and the photoelectric sensor 15 can be changed. By shortening the distance, additional detection data can be obtained, and by comparing the data with the average data obtained in the early stage, a verification function of the detection result can be provided.

[0031] Specifically, when ultraviolet light passes through the ozone layer, the intensity of the light will decay, and the degree of decay is proportional to the concentration of ozone. The photoelectric sensor 15 measures the change in light intensity to determine the current ozone concentration, so the length of the space that the ultraviolet light passes through will also change the final detection result in proportion, so when the motor 8 at the top is started, the ultraviolet light source 14 and the photoelectric sensor 15 are driven to rotate through the movable cover 10, the linkage rod 12 and the rotating ring 13 at the bottom, until the ball 17 at the rear end of the ultraviolet light source 14 and the photoelectric sensor 15 is pressed against the top area of ​​the arc plate 26, the spring 19 can be compressed at this time, the ultraviolet light source 14 and the photoelectric sensor 15 are close to each other, and the distance between the ultraviolet light beam emitted by the ultraviolet light source 14 and the photoelectric sensor 15 is shortened. By obtaining the ozone gas concentration data detected after shortening and comparing it with the data collected in the early stage, the concentration data collected in the early stage can be verified.

[0032] In this embodiment, the driving mechanism 5 includes a motor 8, a movable cover plate 10 and a rotating ring 13. The output end of the motor 8 is inserted with a driving shaft 9, and the end of the driving shaft 9 is welded with a movable cover plate 10. The bottom of the movable cover plate 10 is integrally formed with a sealing ring 11, and the bottom of the sealing ring 11 is integrally formed with a linkage rod 12, and the end of the linkage rod 12 is integrally formed with a rotating ring 13. The surface of the rotating ring 13 is provided with holes, and the ultraviolet light source 14 and the photoelectric sensor 15 pass through the holes on both sides of the rotating ring 13 respectively. The surfaces of the ultraviolet light source 14 and the photoelectric sensor 15 are both provided with a shell 16, and a convex plate 18 is welded on the side of the shell 16. A ball 17 is embedded at the rear end of the shell 16, and a spring 19 is welded on one side of the convex plate 18. The other end of the spring 19 is welded to the surface of the rotating ring 13, the ultraviolet light source 14 and the photoelectric sensor 15 are on the same horizontal axis, the ultraviolet light source 14 and the photoelectric sensor 15 are both pressed against the inner wall of the detection tank 1 or the surface of the arc plate 26 through the ball 17, and the rotating ring 13 is embedded in the detection interlayer 25. The ultraviolet light source 14 and the photoelectric sensor 15 at the bottom are controlled by the driving mechanism 5 at the top to rotate along the detection interlayer 25 area, and the ozone concentration on multiple lines of the same sample can be quickly obtained by means of the rotation process, so that the sample can be detected and processed along multiple different lines in a short time, so that the final detection result is averaged, which improves the validity of the measurement result data.

[0033] Specifically, the movable cover 10 is always pressed on the top of the detection tank 1. By starting the motor 8 to drive the movable cover 10 and the linkage rod 12 to rotate, the rotating ring 13 at the bottom can be driven to rotate synchronously, and the ultraviolet light source 14 and the photoelectric sensor 15 are always symmetrically inserted on both sides of the rotating ring 13. Therefore, after the rotating ring 13 continues to rotate along the detection interlayer 25 area, the area where the ozone gas is detected by the ultraviolet light source 14 and the photoelectric sensor 15 will also continue to change, and finally the ozone concentration data on different paths inside the detection interlayer 25 is realized, and the multiple sets of data results obtained are averaged, so as to improve the accuracy of the final detection result.

[0034] In this embodiment, the movable cover plate 10 is pressed on the top of the detection tank 1, the outer shell of the motor 8 is screwed to the surface of the top plate 4, the linkage rod 12 passes through the inside of the rotating gap 20, and the sealing ring 11 is embedded between the top blocking sleeve 22 and the detection tank 1. The feeding mechanism 6 includes an electric lifting rod 27 and a material storage interlayer 30, the top of the electric lifting rod 27 is screwed with a clamping plate 28, the edge of the clamping plate 28 is attached with a sealing ring 29, and the inner side of the clamping plate 28 is provided with a material storage interlayer 30. A water injection port 31 is provided on the side of the material storage interlayer 30, and a drainage hole is provided inside the material storage interlayer 30, and the inside of the water injection port 31 and the drainage hole are filled with sealing plugs, and the clamping plate 28 is embedded into the bottom blocking sleeve 21 or the top blocking sleeve 22 through the sealing ring 29 on the side. The sample storage assembly 7 includes a sample storage tank 32 and a docking plate 36. The top of the surface of the fixing plate 23 is provided with a plurality of air inlet holes 24. An extraction pipe 33 is inserted into the middle position of the inner side of the sample storage tank 32. The surface of the extraction pipe 33 is provided with a diffusion hole 34. The top of the extraction pipe 33 is connected with a delivery pipe 35. The end of the delivery pipe 35 is inserted into the interior of the docking plate 36, and the interior of the docking plate 36 is partially connected with the air inlet holes 24. The ozone gas inside the external sample storage assembly 7 is drawn in through the feeding mechanism 6 at the bottom to realize the gas drawing detection process. At the same time, the liquid to be tested can be injected after moving down, and then the ozone concentration in the liquid can be directly detected by moving up. Therefore, the measurement state of the ozone gas and the ozone concentration in the liquid can be quickly switched, and the measurement of the two media will not affect the internal measurement environment.

[0035] Specifically, by starting the feeding mechanism 6, when the ozone gas inside the sample storage tank 32 is drawn in, the multiple diffusion holes 34 at the center position can ensure that the drawn ozone can be evenly drawn from different depth areas, so that the drawn ozone gas is more balanced, and the drawing points are not too concentrated, which causes the final detection result to be unable to reflect the actual average concentration inside the sample storage tank 32. When it is necessary to detect the ozone concentration in the liquid containing ozone, the electric lifting rod 27 is directly controlled to move the feeding mechanism 6 downward, and the liquid to be tested is injected into the storage interlayer 30 from the water injection port 31, and then the feeding mechanism 6 is controlled to move upward until the storage interlayer 30 is moved to the same height position as the detection interlayer 25, so that the ozone concentration in the liquid can be directly detected by means of the ultraviolet light source 14 and the photoelectric sensor 15, and the entire detection process will not cause the internal liquid to adhere to the inner wall of the detection tank 1, and when the ozone gas is detected later, the influence of humidity changes on the ozone gas concentration can also be avoided.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
