Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a hydrogen analyzer. Background Technology

[0002] With the continuous development of my country's high-tech industries, including power, chemical, nuclear, semiconductor, and aerospace fields, the demand for various gases is increasing, and the requirements for their purity are also becoming higher. Therefore, the strong demand for high-quality gas measuring instruments has become inevitable. Hydrogen analyzers are involved in both production safety and the reliable guarantee of high-quality industrial products. Therefore, good hydrogen analyzers have always been an important goal for the instrument industry in development and production.

This application can effectively reduce the energy consumption and size of the hydrogen analyzer, and can perform the measurement of hydrogen in binary gases or similar binary gases, facilitating its widespread application in industrial fields such as hydrogen production stations in power plants, chemical synthesis gas production, and nitriding furnaces.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: existing hydrogen analyzers cannot clean and absorb other gases and particulate impurities in the hydrogen to be tested, which can easily affect the test results. At the same time, they cannot buffer the absorbed gas to allow it to enter the instrument smoothly, which can easily affect the sensor and lead to inaccurate test results. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it is impossible to absorb and process impurities and other gases in the hydrogen to be detected while ensuring that the gas to be detected enters the instrument smoothly, and to propose a hydrogen analyzer.

[0006] The technical solution of this utility model is as follows: A hydrogen analyzer, comprising an analyzer body and an inlet port disposed on the top of the analyzer body; further comprising:

[0007] The hydrogen processing mechanism is threaded on the outside of the air inlet and is used to filter impurities in the incoming hydrogen and absorb the remaining gases in the filtered hydrogen.

[0008] The buffer gas delivery mechanism is located at the top of the hydrogen processing mechanism and is used to block the absorbed hydrogen gas, so that it enters the analyzer smoothly.

[0009] And a rotating shaft one, which is rotatably mounted on the hydrogen processing mechanism. A filter plate is installed on the outside of the rotating shaft one. A rotating shaft two is installed below the rotating shaft one. A filter box is installed on the outside of the rotating shaft two. The filter plate is provided with multiple filter holes, which are used to allow hydrogen to pass through and block impurities that are absorbed into the pipeline at the top. The filter box is hollow and is used to hold a molecular sieve. Filter holes are provided on both the top and bottom surfaces of the filter box, which are used to allow hydrogen to pass through so that the molecular sieve can absorb and process the remaining gases in the detection gas.

[0010] Preferably, a display screen is provided on the side of the analyzer body, and a switch is provided on the side of the display screen.

[0011] Preferably, the hydrogen processing mechanism includes a filter tube, an absorption assembly, and a positioning assembly;

[0012] The filter pipe thread is located on the outside of the air inlet;

[0013] The absorption component is located inside the filter tube and is used to absorb the remaining gas in the detection gas.

[0014] The positioning component is located on the outside of the filter tube and is used to rotate and adjust the filter box and filter plate, and then fix their positions after adjustment.

[0015] Preferably, the absorption assembly includes a placement box and a straight slide rail;

[0016] The straight slide rail is set on the filter tube, and the placement box is slidably set on the straight slide rail.

[0017] Preferably, the positioning assembly includes a socket, a rod, a rotating plate, and a spring;

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] 1. Through the hydrogen processing mechanism, the filter plate filters and removes particulate impurities in the gas to be detected. The molecular sieve in the filter box and the activated carbon in the placement box absorb the remaining gases in the gas to be detected. This effectively removes these impurities, ensuring that hydrogen enters the analyzer smoothly, thereby improving the accuracy of the measurement. At the same time, it avoids impurities interfering with the hydrogen detection signal, which could lead to deviations in the measurement results. Absorbing the remaining gases can increase the hydrogen concentration, more accurately reflecting the actual hydrogen concentration, improving the accuracy of the measurement, and also reducing damage to the sensor and extending the sensor's service life.

[0023] 2. By setting up a buffer gas delivery mechanism, the gas to be detected is absorbed into the rotating tube and blocked by the spiral blades. Then, the motor drives the spiral blades to rotate, thereby slowly delivering the gas to be detected. This can reduce gas flow rate and pressure fluctuations, avoid loosening of sensor elements or deformation of precision parts, extend the service life of the equipment, and reduce the dynamic pressure on the seals, maintaining the airtightness of the system.

[0030] Example 1

[0031] like Figures 1-5As shown, the present invention proposes a hydrogen analyzer, which includes an analyzer body 1, an air inlet 6 disposed on the top of the analyzer body 1, a hydrogen processing mechanism, a buffer gas delivery mechanism, and a rotating shaft 502.

[0032] The hydrogen treatment mechanism is threaded on the outside of the air inlet 6, used to filter impurities in the incoming hydrogen and absorb the remaining gases in the filtered hydrogen.

[0033] The buffer gas delivery mechanism is located at the top of the hydrogen processing mechanism to block the absorbed hydrogen gas and allow it to enter the analyzer smoothly.

[0034] A rotating shaft 502 is rotatably mounted on a hydrogen processing mechanism. A filter plate 503 is installed on the outer side of the rotating shaft 502. A rotating shaft 511 is located below the rotating shaft 502. A filter box 508 is installed on the outer side of the rotating shaft 511. The filter plate 503 has multiple filter holes for passing hydrogen through and blocking impurities that are absorbed into the pipeline. The filter box 508 is hollow and is used to hold a molecular sieve. Filter holes are provided on both the upper and lower surfaces of the filter box 508 for passing hydrogen through so that the molecular sieve can absorb and process the remaining gases in the detection gas.

[0035] The analyzer body 1 has a display screen 2 on its side, and a switch 3 on its side. The display screen 2 is used to observe and record the concentration of hydrogen gas detected, and the switch 3 is used to control various functions of the analyzer body 1.

[0036] The hydrogen treatment mechanism includes a filter tube 501, an absorption assembly, and a positioning assembly. The filter tube 501 is threaded on the outside of the air inlet 6. The absorption assembly is located on the inside of the filter tube 501 and is used to absorb and treat the remaining gas in the detection gas. The positioning assembly is located on the outside of the filter tube 501 and is used to rotate and adjust the filter box 508 and the filter plate 503, and fix their positions after adjustment. The absorption assembly includes a placement box 510 and a straight slide rail 509. The straight slide rail 509 is disposed on the filter tube 501, and the placement box 510 is slidably disposed on the straight slide rail 509. The filter box 508 is used to store activated carbon, which absorbs all gases except hydrogen in the detection gas. The side of the placement box 510 closest to the filter tube 501 is provided with filter holes to facilitate the entry of the detection gas into the placement box 510 for processing. The side of the placement box 510 away from the filter tube 501 is provided with a partition. The height of both ends of the placement box 510 is higher than the placement box 510 itself, so the placement box 510 can be limited to prevent it from falling off the filter tube 501. The positioning assembly includes a socket 507, a rod 505, a rotating plate 504, and a spring 506. The rotating plate 504 is located at the end of the first rotating shaft 502, and the end of the second rotating shaft 511 is also equipped with a rotating plate 504. The rod 505 is slidably disposed on the side of the rotating plate 504, and the spring 506 is located on the outside of the rod 505. The socket 507 is located on the filter tube 501. When the rod 505 is pulled to disengage from the socket 507, the first rotating shaft 502 or the second rotating shaft 511 can be rotated. There are two sockets 507. After rotating to the appropriate position, the rod 505 is released so that it is inserted into the socket 507 at that position under the action of the spring 506. The filter tube 501 is then removed from the air inlet 6. Then, the filter plate 503 or the filter box 508 is adjusted so that one of them is kept vertical and fixed, so that the other can be cleaned, keeping the filter plate 503 and the filter box 508 clean and tidy.

[0037] Example 2

[0038] like Figures 2-3 As shown, this utility model proposes a hydrogen analyzer. Compared with Embodiment 1, this embodiment details the structure of the buffer gas delivery mechanism.

[0039] The buffer gas delivery mechanism includes a motor 401, a rotating shaft 402, a spur gear 403, and a gear ring 404. The motor 401 is located on the top of the analyzer body 1. The rotating shaft 402 is located at the output end of the motor 401. The spur gear 403 is located on the top of the rotating shaft 402. The gear ring 404 is located on the side of the spur gear 403. A rotating tube 405 is located inside the gear ring 404. A spiral blade 408 is located inside the rotating tube 405. A connecting shaft 407 is located at the axis of the spiral blade 408. A connecting rod is rotatably mounted at the end of the rotating tube 405. Connector 406 is used to connect the bottom of the filter tube 501 and the top of the hydrogen delivery tube. The motor 401 is started, which drives the rotating shaft 402 to rotate. The rotating shaft 402 drives the gear ring 404 to rotate through the spur gear 403. The gear ring 404 drives the rotating tube 405 to rotate. The rotating tube 405 drives the spiral blade 408 to rotate. After the gas in the hydrogen delivery tube enters the pipe, it impacts the spiral blade 408. The spiral blade 408 rotates and transports the internal hydrogen, making the delivery process smoother.

[0040] In summary, when using this utility model, the top of the connecting pipe 406 is connected to the hydrogen delivery pipe, and the bottom of the filter pipe 501 is connected to the air inlet 6 on the analyzer body 1. Then, the motor 401 is started to deliver hydrogen. The motor 401 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the gear ring 404 to rotate through the circular gear 403. The gear ring 404 drives the rotating pipe 405 to rotate, and the rotating pipe 405 drives the spiral blade 408 to rotate. After the gas in the hydrogen delivery pipe enters the pipe, it impacts the spiral blade 408. The spiral blade 408 rotates and transports the internal hydrogen, thus smoothly delivering it into the filter pipe 501. The hydrogen first passes through the filter plate 503 to filter out particulate impurities. After filtration, it then passes through... Placement box 510 and filter box 508 treat gases other than hydrogen through internal activated carbon and molecular sieves. After treatment, the hydrogen enters the analyzer body 1 for detection, and the detection results are displayed and recorded on the display screen 2. After detection, the filter tube 501 is rotated to remove it. The placement box 510 is moved so that its perforated side is attached to the inner wall of the filter tube 501 to avoid affecting the rotation of the filter plate 503 and filter box 508. The insertion rod 505 is pulled to disengage it from the insertion hole 507. Then, the filter plate 503 or filter box 508 is adjusted so that one of them is kept vertical and fixed. After adjustment, the insertion rod 505 is released so that it is locked in the insertion hole 507 at that position under the action of the spring 506, so that the other one can be cleaned.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
