Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen recovery, and specifically discloses a hydrogen recovery, purification and recycling device. Background Art

[0002] Hydrogen is a single substance formed by the hydrogen element, with the chemical formula H2 and a molecular weight of 2.01588. At room temperature and pressure, hydrogen is a colorless, odorless, highly flammable and insoluble gas in water. The density of hydrogen is 0.089g / L (101.325kpa, 0°C), which is only 1 / 14 of air. It is the gas with the smallest density known in the world, so hydrogen can be used as a filling gas for airships and hydrogen balloons (due to the flammability of hydrogen and its low safety, airships are now mostly filled with helium). Hydrogen shows reducing properties when reacting with non-metals with high electronegativity, and shows oxidizing properties when reacting with active metals.

[0003] Hydrogen has broad application prospects in the energy field. In addition to being used as a fuel for hydrogen-oxygen fuel cells, hydrogen can also be used in chemical production, metallurgical industry, food processing and other fields. However, the production cost of hydrogen is relatively high, and if it is directly discharged into a processing device for treatment and then discharged after use, it is relatively wasteful. It is generally purified through a hydrogen recovery device and recycled.

[0004] The Chinese patent application number CN202310429200.8 discloses a purified hydrogen storage device and a purified hydrogen storage method, which can improve the density and stability of hydrogen storage and reduce energy consumption. The purified hydrogen storage device includes a hydrogen transmission pipeline, a purified hydrogen storage unit and a circulating liquid bath unit. The purified hydrogen storage unit includes a hydrogen purification tank group filled with a first metal hydride hydrogen storage material and a hydrogen storage tank group filled with a second metal hydride hydrogen storage material, and the hydrogen purification tank group and the hydrogen storage tank group are sequentially installed in series on the hydrogen transmission pipeline along the hydrogen transmission direction. The circulating liquid bath unit includes a first liquid bath room for accommodating the hydrogen purification tank group, a second liquid bath room for accommodating the hydrogen storage tank group, and a circulating infusion tank; the second liquid bath room and the first liquid bath room are sequentially installed in series on the circulating infusion pipeline of the circulating infusion tank along the infusion direction, and are used to circulate liquid to the second liquid bath room and the first liquid bath room through the circulating infusion tank.

[0005] However, when hydrogen is purified through a hydrogen purification tank group, since each purification tank is connected by a pipeline, leakage may occur, resulting in reduced purification efficiency, affecting the overall performance of the purified hydrogen storage device, reducing hydrogen recovery efficiency, and even causing safety accidents due to large-scale hydrogen leakage.

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] 1. The present application is provided with an anti-leakage detection frame and a gas leakage detection mechanism, which can effectively detect the leakage of hydrogen during the purification and recycling process, so as to timely discover the hydrogen leakage and repair the purification and recycling mechanism to reduce safety hazards.

[0019] 2. When the gas leak detection mechanism is conducting hydrogen leak detection, the output shaft Ⅰ of the dual-axis motor drives the turntable to rotate, and transmits the motion to the swing rod through the clamping rod, causing the swing rod to swing back and forth. The movement of the swing rod is transmitted to the rack rod through the fan-shaped teeth, causing the rack rod to move back and forth in parallel, driving the gas detector to slide back and forth along the slide groove of the connecting rod Ⅰ.

The swinging setting of the exhaust fan enables the gas detector to perform a more comprehensive detection of the entire row of purification tanks, and can achieve rapid response and effective control of hydrogen leakage. At the same time, the exhaust port effectively absorbs the leaked hydrogen, reducing the risk of explosion and fire.

[0021] 4. When a more detailed and accurate inspection is required for a specific area, the operator starts the motor, the gear rotates, the slide bar with the tooth block slides, the extended shell moves, the extended gas extraction port moves to the specific area, and the gas in the area is extracted.

[0048] The present embodiment realizes the swing of the vacuum pump 39 through the following structure, the vacuum mechanism 3 also includes a support block 31, a rotating rod mounting block 32, a rotating rod I 33, a rotating plate 34, a rotating ring 35, a spherical rocker 36, a U-shaped connecting frame 37 and a rotating rod II 38; the support block 31 is fixed on the top plate 23; the rotating rod mounting block 32 is fixed on the support block 31; the rotating rod I 33 rotates through the rotating rod mounting block 32, the first end of the rotating rod I 33 is fixedly connected to the output shaft II of the dual-axis motor 25, and the second end of the rotating rod I 33 is fixedly connected to the rotating shaft II of the dual-axis motor 25.

[0049] The working process of the above hydrogen recovery, purification and recycling device is as follows:

[0050] When hydrogen leakage detection is performed, the dual-axis motor 25 is started, the turntable 26 rotates, and the rotational motion of the turntable 26 is transmitted through the clamping rod 29. The clamping rod 29 slides in the elliptical slide groove 28 of the swing rod 27, thereby driving the swing rod 27 to swing. The swinging motion of the swing rod 27 is transmitted to the rack rod 45 through the fan-shaped teeth 210, so that the rack rod 45 moves back and forth along the rack rod connecting block 213 in a straight line. The movement of the rack rod 45 drives the gas detector mounting plate 41 to move back and forth along the connecting rod I 21, thereby realizing the scanning detection of the gas detector 43 along the anti-leakage detection frame 2. The precise mechanical transmission process ensures the high efficiency and accuracy of hydrogen leakage detection.

[0051] At the same time, the exhaust mechanism 3 starts to start and enters the working state. The rotating plate 34 and the rotating ring 35 start to rotate under the drive of the dual-axis motor 25 and the coordinated action of the rotating rod I 33. The rotation of the rotating plate 34 causes the spherical pendulum 36 to swing and rotate. The swinging and rotation of the spherical pendulum 36 drives the U-shaped connecting frame 37 to swing and rotate accordingly, causing the rotating rod II 38 to rotate, and the exhaust fan 39 swings accordingly. When the gas detector 43 slides toward the first side of the anti-leakage detection frame 2, the exhaust port 393 of the exhaust fan 39 swings toward the first side of the anti-leakage detection frame 2 with the gas detector 43, and the exhaust port 392 of the exhaust fan 39 swings toward the second side of the anti-leakage detection frame 2. When the detector 43 slides toward the second side of the anti-leakage detection frame 2, the vacuum fan 39 swings in the opposite direction, ensuring that the exhaust ports 393 of the multiple vacuum fans 39 are always close to the gas detector 43, and the vacuum port 392 can effectively absorb the gas in the area far away from the gas detector 43, so that the gas detector 43 can always and comprehensively monitor whether there is hydrogen leakage around the purification and recycling mechanism 1, thereby improving the detection efficiency and safety. The precise linkage mechanism not only improves the sensitivity of gas detection, but also ensures the efficient operation of the entire device, and can also prevent hydrogen from accumulating in the detection area, thereby reducing the risk of explosion and fire, enhancing the safety performance of the device, and providing a safer working environment for operators.

[0052] The vacuum pump 39 includes a fixed vacuum port 392 and a retractable extended vacuum port 3912, which can perform more detailed and precise detection of specific areas. The operator starts the motor 3910, and the gear 3911 connected thereto begins to rotate. The sliding rod 3914 fixed with a plurality of tooth blocks 3915 slides along the slide groove of the slide groove plate 395, and the other sliding rods 3914 will slide accordingly, so as to adjust the distance between the extended vacuum port 3912 and the vacuum port 392. Through the above design, the vacuum pump 39 can achieve more precise detection of the area around the purification and recycling mechanism 1, which not only improves the efficiency of hydrogen leakage detection, but also ensures the accuracy and safety of the detection process.

[0053] In order to further improve the sensitivity and reliability of detection, the above-mentioned hydrogen recovery, purification and recycling device is also equipped with an advanced control center. The gas detector 43 in the gas leakage detection mechanism 4 can monitor the concentration of hydrogen in real time and transmit the data to the control center. The control center will automatically adjust the detection parameters according to the data provided by the gas detector 43 to ensure the accuracy of the detection process. In addition, the control center also has a self-diagnosis function, which can monitor the operating status of the purification and recycling mechanism 1, the anti-leakage detection frame 2, the gas leakage detection mechanism 4 and the exhaust mechanism 3 in real time during the detection process. Once an abnormality is found, the control center will immediately sound an alarm and take corresponding emergency measures to prevent the occurrence of hydrogen leakage accidents. The entire detection process not only relies on precise mechanical transmission, but also relies on advanced electronic technology and intelligent control systems, thereby ensuring the efficiency, accuracy and safety of hydrogen leakage detection.

[0054] The design of the entire hydrogen recovery, purification and recycling device fully considers safety and efficiency. Through the coordinated work of the gas leakage detection mechanism 4 and the exhaust mechanism 3, the hydrogen leakage problem can be monitored and handled in real time, ensuring the safety and reliability of the hydrogen purification process, thereby providing a guarantee for the stable operation of the entire device. Through the efficient monitoring and processing mechanism, the risk of hydrogen leakage is greatly reduced, ensuring the safety of the entire hydrogen recovery and purification process, and at the same time improving the detection efficiency, so that the hydrogen leakage problem can be quickly discovered and handled in time, thereby ensuring the efficient operation of the entire device.
