Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, and more specifically, to a testing device for ozone decomposition catalysts. Background Art

[0002] An ozone decomposition catalyst is a device used for catalytically decomposing ozone. With the continuous progress of technology, some instruments will generate a large amount of ozone during operation. The excessive generation of ozone is likely to affect the environmental climate, so it is necessary to use a catalyst for catalytic decomposition. Different catalysts have different effects on the catalytic decomposition of ozone. Therefore, a testing device is needed to detect the speed and effect of the catalyst in catalytically decomposing ozone, etc.

In the above prior art, ozone is generated by the ozone generator, and then the catalyst is injected. Then, by installing ozone detectors at both ends of the ozone and catalyst mixing delivery pipe, the ozone detectors are used to detect the injection end and the discharge end of ozone and the catalyst, so as to obtain the catalytic effect of the catalyst on ozone.

Although the final catalytic effect of the catalyst on ozone can be detected, during the catalytic process of the catalyst on ozone, it is inconvenient to measure the catalytic speed of the catalyst at a certain period and whether there is still a catalytic effect, which leads to incomplete test results.

Detailed Embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0022] As Figure 1 - Figure 4 shown, the present utility model provides a technical solution: an ozone decomposition catalyst testing device, which includes a base 1. A testing pipeline 11 is arranged in the middle of the base 1. One end of the testing pipeline 11 is fixedly connected with an ozone generator 12, and the lower end of the ozone generator 12 is fixedly connected to the base 1. One end of the testing pipeline 11 close to the ozone generator 12 is respectively fixedly connected with a first ozone detector 13 and a catalyst injector 14. The end of the testing pipeline 11 far from the first ozone detector 13 is fixedly connected with a second ozone detector 15. An adjusting component is fixedly connected to the outer side of the middle section of the testing pipeline 11. A detecting component is meshed with the outer side of the middle section of the adjusting component. One end of the detecting component is fixedly connected with a display component, and the lower end of the display component is fixedly connected to the adjusting component. When using a catalyst for ozone catalytic testing, first use the ozone generator 12 and the catalyst injector 14 to inject ozone and the catalyst into the testing pipeline 11 respectively. After injection, the catalyst starts to catalytically decompose ozone. During this process, the initial catalytic value can be detected by the first ozone detector 13, and the final catalytic value can be detected by the second ozone detector 15. When it is necessary to detect the catalytic value at a certain period of time, the adjusting component can be started. After the adjusting component operates, it drives the detecting component to move. When the detecting component moves to a suitable position, the catalytic value is detected by the detecting component, and the detection result is displayed through the display component, so that when the ozone decomposition catalyst testing device is used, different stages of the catalytic decomposition of ozone by the catalyst can be detected according to the detection requirements, and thus a more comprehensive test result can be obtained.

[0023] As Figure 1 and Figure 3 shown, a protective component is arranged outside the ozone generator 12. The protective component includes a first protective cover 5 sleeved outside the ozone generator 12. The lower end of the first protective cover 5 is fixedly connected to the base 1. A filter screen 51 is fixedly connected to the inner side of the upper end of the first protective cover 5. One end of the base 1 far from the first protective cover 5 is fixedly connected with a second protective cover 52. During use, the ozone generator 12 is protected by the first protective cover 5 and the filter screen 51, and the filtering component is protected by the second protective cover 52.

[0024] As Figure 1 and Figure 2As shown, a filtering component is provided inside the second protective cover 52. The filtering component includes an ozone purifier 6 inserted inside the second protective cover 52. The lower end of the ozone purifier 6 is fixedly connected to the base 1. One end interface of the ozone purifier 6 close to the test pipeline 11 is fixedly connected to the test pipeline 11 by bolts. The upper end of the ozone purifier 6 is fixedly connected with an exhaust pipe 61. The upper end of the exhaust pipe 61 penetrates through the second protective cover 52. The ozone discharged from the tail end of the test pipeline 11 enters the ozone purifier 6 and is filtered by the ozone purifier 6 and then discharged from the exhaust pipe 61, which is convenient for treating the ozone tail gas generated by the test.

[0025] As Figure 1 and Figure 4 shown, the adjusting component includes a housing 2 fixedly connected to the outer side of the middle end of the test pipeline 11. One outer side of the housing 2 is fixedly connected with a motor 21. The output shaft of the motor 21 is fixedly connected with a threaded rod 22. The end of the threaded rod 22 far from the motor 21 is rotatably connected to the housing 2. A threaded column 23 is fixedly connected to the outer side of the middle end of the threaded rod 22. When the motor 21 is started, the output shaft of the motor 21 drives the threaded rod 22 to rotate under the support of the housing 2. After the threaded rod 22 rotates, through the engagement with the threaded column 23, the threaded column 23 drives the detection component to move, which is convenient for adjusting the position of the detection component.

[0026] As Figure 3 and Figure 4 shown, the detection component includes a third ozone detector 3 fixedly connected to the outer side of the middle end of the threaded column 23. One end of the third ozone detector 3 close to the threaded column 23 is fixedly connected with a signal transmitter 31. A signal receiver 32 is arranged on the outer side of the housing 2. The ozone decomposition effect here is detected by the third ozone detector 3. The detection result is sent out by the signal transmitter 31, and the signal sent out by the signal transmitter 31 is received by the signal receiver 32, which is convenient for detecting the content of ozone.

[0027] As Figure 3 shown, the display component includes a bracket 4 fixedly connected to one end of the signal receiver 32 close to the housing 2. One end of the bracket 4 close to the housing 2 is fixedly connected to the housing 2. The upper end of the bracket 4 is fixedly connected with a display screen 41. The lower end of the display screen 41 is fixedly connected with a signal transmission line 42. One end of the signal transmission line 42 far from the display screen 41 is fixedly connected to the signal receiver 32. After the signal sent out by the signal transmitter 31 is received by the signal receiver 32, the data is input into the display screen 41 through the signal transmission line 42 for display, which is convenient for displaying the detection result.

[0028] Working principle: When testing the ozone decomposition catalyst, first start the ozone generator 12 and the catalyst injector 14 to inject ozone and the catalyst into the test pipeline 11. At this time, the concentration of ozone during injection is detected by the first ozone detector 13. Then, when the ozone and the catalyst flow to the end of the test pipeline 11 in the test pipeline 11, the concentration of ozone is detected by the second ozone detector 15 at this time. During the flow of ozone, when it is necessary to detect the ozone decomposition effect of a certain section in the test pipeline 11, start the motor 21. The output shaft of the motor 21 drives the threaded rod 22 to rotate under the support of the housing 2. After the threaded rod 22 rotates, through meshing with the threaded column 23, the threaded column 23 drives the third ozone detector 3 and the signal transmitter 31 to move. When the third ozone detector 3 moves to a suitable position, turn off the motor 21 at this time. Then, the ozone decomposition effect here is detected by the third ozone detector 3, and the detection result is sent out by the signal transmitter 31. The signal sent out by the signal transmitter 31 is received by the signal receiver 32 and the data is input into the display screen 41 through the signal transmission line 42 for display. The ozone discharged from the end of the test pipeline 11 enters the ozone purifier 6 and is filtered by the ozone purifier 6 and then discharged from the exhaust pipe 61. During the use of the ozone generator 12 and the ozone purifier 6, the ozone generator 12 is protected by the first protective cover 5 and the filter screen 51, and the ozone purifier 6 is protected by the second protective cover 52.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them.
