Description

Technical Field

[0001] This invention relates to the field of hydrogen purification technology, and more specifically to a hydrogen purification device after hydrogen production. Background Technology

[0002] Water electrolysis is a relatively convenient method for producing hydrogen. Direct current is passed through an electrolytic cell filled with electrolyte, causing water molecules to undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen. It is easy to see from the principle that hydrogen produced by electrolysis typically contains small amounts of oxygen and gaseous water. Since hydrogen is used as a chemical raw material and energy carrier, its purity and impurity content have different requirements for different applications. Therefore, hydrogen purification is an essential step in the water electrolysis process.

[0003] Hydrogen purification essentially involves separating hydrogen from impurities. Hydrogen purification requires specific purification equipment and a series of purification processes on that equipment.

[0004] In the existing technology, hydrogen purification devices are used to purify hydrogen produced by electrolysis. Due to the large number of pipes and valves in the purification device, the pipe joints and valves are prone to aging after long-term use. This may lead to hydrogen leakage during the purification process, which will reduce the purification efficiency of the purification device, affect the overall performance of the purification device, and may even cause safety accidents due to large-scale hydrogen leakage.

[0043] As a technical optimization scheme of the present application, the cleaning mechanism includes a mounting seat 28 mounted on the telescopic end of the other first electric telescopic rod 19, a rotating block 30 rotatably mounted in the mounting seat 28, a first arc-shaped plate 10 mounted on one end of the rotating block 30 away from the mounting seat 28, a plurality of mounting plates 31 mounted on the top of the first arc-shaped plate 10, and an industrial camera 32 mounted on the outer wall of one side of the plurality of mounting plates 31.

[0044] As a technical optimization scheme of the present application, the outer wall of one side of the first arc-shaped plate 10 away from the rotating block 30 is provided with an arc-shaped groove 33, the arc-shaped groove 33 is provided with an electric sliding block 34, the second arc-shaped plate 29 is mounted on one end of the electric sliding block 34 away from the arc-shaped groove 33, two groups of arc-shaped brushes 35 are mounted on the inner wall of the second arc-shaped plate 29, a dust suction port 38 is arranged at the central position of the inner wall of the second arc-shaped plate 29, and a sound sensor 37 is mounted in the inside of both ends of the second arc-shaped plate 29.

[0045] As a technical optimization scheme of the application, the second arc-shaped plate 29 is provided with a circular hole 39 between the two groups of arc-shaped brushes 35, a second electric telescopic rod 40 is installed inside the circular hole 39, an ultrasonic thickness gauge probe 41 is installed at the telescopic end of the second electric telescopic rod 40, two fourth sliding grooves 42 are formed in the inner walls of the two sides of the second arc-shaped plate 29, fourth sliding blocks 43 are installed inside the two fourth sliding grooves 42, a protective plate 36 for shielding and protecting the ultrasonic thickness gauge probe 41 is jointly installed at the ends of the two fourth sliding blocks 43 away from the fourth sliding grooves 42, and a polishing surface is arranged on the outer wall of the side of the protective plate 36 away from the two fourth sliding blocks 43.

[0046] In the application, when a user uses the device, the hydrogen gas prepared by electrolysis in the PEM electrolytic cell is transported to the inside of the device body 2 through the conveying pipe, and the deoxidizer, the dryer, the gas-water separator, the cooler, the filter, the water collector and other components arranged inside the device body 2 cooperate with each other, so that the oxygen and other gases and water vapor contained in the hydrogen gas can be filtered and separated, and the prepared hydrogen gas can be purified.

[0047] During the use of the device body 2, one of the rotating rods 8 located on the front and rear sides of the device body 2 can be controlled to drive the multiple components of the detection mechanism to rotate and adjust synchronously, so that after the two detection mechanisms are rotated to be horizontal, the two rotating plates 22 can be controlled to rotate and adjust at one end of the corresponding moving seat 21, the hydrogen leak detector probes 26 at the bottom ends of the two rotating plates 22 are driven to rotate to be close to each other, then the two second sliding blocks 14 are moved up and down inside the corresponding second sliding grooves 12, one of the third sliding blocks 18 is moved horizontally inside the corresponding third sliding groove 13, the multiple components of the detection mechanism are moved to be close to the joint parts of the pipelines 3 and the valve parts 4 of the device body 2, the first electric telescopic rod 19 is controlled to be elongated, the moving plate 9 and the two rotating plates 22 are moved towards the joint parts of the pipelines 3 and the valve parts 4 of the device body 2, the second double-headed screw rod 23 is controlled to drive the two rotating plates 22 to move and adjust towards each other or away from each other, and the hydrogen leak detector probes 26 are ensured to be close to the joint parts of the pipelines 3 and the valve parts 4 that need to be detected, so that the hydrogen leak detector can automatically detect the parts of the device body 2 that are prone to hydrogen leakage, and the safety of the device body 2 during use is improved.

[0048] And in the process of the above-mentioned hydrogen leak detector automatically detecting the parts prone to hydrogen leakage on the device body 2, the relevant leak detection liquid can be injected into the preset liquid injection equipment, and one end of the two rotating plates 22 installed with multiple spray heads 25 is rotated to a position close to each other. At this time, multiple spray heads 25 can spray leak detection liquid on the pipe 3 joint part and the surface of the valve 4 on the device body 2, and observe whether bubbles are generated, so as to detect whether hydrogen leaks by means of leak detection liquid, and recheck the pipe 3 joint part and the valve 4 on the device body 2 by the hydrogen leak detector, further improve the detection accuracy of hydrogen leakage on the device body 2, and facilitate safe purification of hydrogen on the device body 2.

[0049] During use of the device body 2, the staff need to regularly check the relevant safety facilities to ensure that they can be used normally. When checking the gas interception capacity of the valve 4 on the device body 2, the multiple components of the detection mechanism can be moved to the position close to one of the valves 4 by means of the up and down movement adjustment of the two second sliding blocks 14 in the corresponding second sliding grooves 12 and the horizontal movement adjustment of the corresponding third sliding block 18 in the third sliding groove 13. The second double-headed screw 23 drives the two moving seats 21 and the rotating plates 22 to move towards each other, and the rubber pads 24 provided on the side walls of the two rotating plates 22 are tightly abutted against the outer wall of the valve 4, so that the two rotating plates 22 can tightly clamp and fix the valve 4. The first drive motor provided in the third sliding block 18 drives the first electric telescopic rod 19 and the moving plate 9 and other components to rotate forward and backward, so as to realize the automatic tightening and loosening operation of the valve 4. Subsequent other valves 4 can continue to be adjusted by means of the up and down movement of the two second sliding blocks 14 in the corresponding second sliding grooves 12 and the horizontal movement of the third sliding block 18 in the third sliding groove 13, so that the multiple components of the detection mechanism can be moved to the positions close to the other valves 4 in turn, and the above-mentioned automatic tightening and loosening operation of the valve 4 can be repeated. This facilitates automatic checking of multiple valves 4, and the staff do not need to manually tighten and loosen multiple valves 4 in turn, thereby improving the checking efficiency of multiple valves 4 on the device body 2.

[0050] In order to further improve the safety of the device body 2 in the process of purifying hydrogen, it is necessary to clean the dust and other impurities on the surface of the device body 2. At this time, the other two rotating rods 8 can be controlled to drive the corresponding cleaning mechanism components to rotate to the horizontal state, ensuring that the cleaning mechanism located in the front of the device body 2 is located between the two pipes 3. At this time, the corresponding two first electric telescopic rods 19 can be controlled to extend the extension end together, driving the two second arc-shaped plates 29 to abut the outer wall of one of the tanks in the device body 2. Since the inner diameters of the two second arc-shaped plates 29 are adapted to the outer diameter of the tank, after the two second arc-shaped plates 29 abut the outer wall of the tank, it can be ensured that the two groups of arc-shaped brushes 35 arranged on the inner wall thereof completely abut the outer wall of the tank. The cleaning mechanism located in the front of the device body 2 is subject to the obstruction of the pipe 3, and its up-down movement range is smaller. The cleaning mechanism located in the front of the device body 2 can be moved up and down within a certain range by means of the two second sliders 14. After cleaning a part of the impurities on the outer wall of the tank, the cleaning mechanism located in the back of the device body 2 and its corresponding two second sliders 14 can be moved up and down to clean the impurities on the vertical position of the back of the tank. At the same time, the electric slider 34 located in the back of the device body 2 can move back and forth in the corresponding arc-shaped slot 33, driving the second arc-shaped plate 29 to rotate transversely on the surface of the tank, so as to assist in cleaning the parts that cannot be cleaned by the cleaning mechanism located in the front of the device body 2, thereby improving the quality and efficiency of cleaning the impurities on the surface of the tank.

[0051] Since the dust suction port 38 is arranged on the inner wall of the two second arc-shaped plates 29, the two groups of arc-shaped brushes 35 on the inner wall of the two second arc-shaped plates 29 can clean the impurities on the surface of the tank at the same time, and the dust suction port 38 can simultaneously suck the cleaned impurities, avoiding the problem of impurities escaping everywhere and easily causing secondary pollution on the surface of the device body 2.

[0052] And after the surface impurities of the tank body are cleaned, the two second sliding blocks 14 move up and down inside the corresponding second sliding grooves 12, and the two third sliding blocks 18 move horizontally inside the corresponding third sliding grooves 13, which can synchronously drive the multiple industrial cameras 32 arranged at the top of the two first arc-shaped plates 10 to detect the quality of the surface of the tank body in real time. If it is found that there is paint peeling or other phenomena at a certain position of the tank body, the cleaning mechanism located on the front or back of the device body 2 can be moved to the position close to the defective part of the tank body after ensuring that there is no hydrogen gas in the device body 2, and the corresponding first electric telescopic rod 19 is controlled to extend the telescopic end, so that the corresponding second arc-shaped plate 29 abuts against the outer wall of the tank body, and then the second arc-shaped plate 29 is moved horizontally by the electric sliding block 34, so that the protective plate 36 arranged on the inner wall of the second arc-shaped plate 29 is moved to the position where the defect exists on the surface of the tank body. The outer wall of the protective plate 36 can automatically polish the position where the defect exists on the surface of the tank body, so that the paint with rust or peeling is polished clean, and then the staff can re-paint the polished outer wall of the tank body, thereby improving the efficiency of processing the defects on the surface of the tank body.

[0053] Moreover, since the two second arc-shaped plates 29 are provided with sound sensors 37 and ultrasonic thickness gauges 41, the telescopic ends of the two first electric telescopic rods 19 can be controlled to extend regularly, so as to push the two second arc-shaped plates 29 to abut against the outer wall of the tank body, and the two fourth sliding blocks 43 are controlled to move downward inside the corresponding fourth sliding grooves 42, so as to drive the two protective plates 36 to slide downward and remove the shielding protection of the ultrasonic thickness gauge probes 41. At this time, the telescopic ends of the two second electric telescopic rods 40 are controlled to extend together, so as to drive the two ultrasonic thickness gauge probes 41 to abut against the outer wall of the tank body, thereby facilitating the detection of the wall thickness of the tank body, recording the detection data of the wall thickness of the tank body, evaluating the structural strength and safety, verifying whether the tank body has sufficient strength to withstand the design pressure, avoiding catastrophic accidents such as local deformation, rupture or explosion caused by insufficient wall thickness; and quantifying the corrosion rate of the tank body, evaluating the remaining corrosion allowance of the tank body, and ensuring that repair or replacement measures are taken before the design life is reached; through long-term wall thickness data tracking, it can be verified whether the tank body has reached the design life, or the inspection period is adjusted according to the actual corrosion condition, so as to realize the risk-based inspection strategy.

[0054] The sound sensor 37 is in abutment with the outer wall of the tank body, and when the tank body has a slight leakage, the medium flowing out will generate a specific frequency of turbulent flow sound or hissing sound. The sound sensor 37 can capture these early signals much earlier than obvious signs such as pressure drop or medium overflow, gaining time for emergency shutdown or maintenance; and when the internal components or external accessories of the tank body are loose, abnormal knocking or rubbing sounds will be generated due to vibration, and the sound sensor 37 can quickly identify such problems to prevent parts from falling off and damaging the equipment; even when the cracks in the inner wall of the tank body expand due to corrosion, fatigue or mechanical impact, they will be accompanied by changes in friction or vibration sound. By continuously monitoring the sound spectrum through the sound sensor 37, the damage location can be located and the severity can be evaluated to prevent crack propagation from causing a burst, so that the device body 2 has higher safety during use and reduces the occurrence of safety accidents.

[0055] Since the first arc-shaped plate 10 can be adjusted in rotation by the rotating block 30 inside the mounting seat 28, driving the second arc-shaped plate 29 to rotate upward to a vertical state, the two rotating plates 22 above which are provided with one end of the plurality of spray heads 25 are rotated to the bottom end, and the distance between the two rotating rods 8 is reduced by the two first double-headed screws 16, so that the two rotating plates 22 are closer to the inner wall of the second arc-shaped plate 29, and the first electric telescopic rods 19 are telescoped at the corresponding telescopic ends to ensure that the two rotating plates 22 are located directly above the second arc-shaped plate 29. At this time, by controlling the plurality of spray heads 25, the neutral cleaning agent injected into the inside of the external pre-set liquid spraying device is sprayed downward on the inner wall of the second arc-shaped plate 29, and at the same time, the two rotating plates 22 are slowly adjusted in rotation to ensure that the plurality of spray heads 25 can uniformly spray the neutral cleaning agent on the surfaces of the two groups of arc-shaped brushes 35, so that the subsequent two groups of arc-shaped brushes 35 can better clean the impurities on the surface of the tank body in cooperation with the neutral cleaning agent, further improving the quality of cleaning the surface of the tank body.
