Description

Technical Field

[0001] This invention relates to the field of water electrolysis hydrogen production technology, specifically a high-pressure electrolyzer for water electrolysis hydrogen production. Background Technology

[0002] Hydrogen production via water electrolysis is a relatively convenient method. Direct current is passed through an electrolytic cell filled with potassium hydroxide or sodium hydroxide. Water molecules undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen. The hydrogen and oxygen produced by the chemical reaction need to be collected. During this collection process, some problems may arise. The positive electrode decomposition produces oxygen, while the negative electrode decomposition produces hydrogen. Both hydrogen and oxygen can leak, but hydrogen leaks are more hazardous than oxygen leaks. Therefore, leaked hydrogen needs to be collected and treated. Oxygen decomposition at the positive electrode displaces potassium or calcium ions in the molten metal, producing potassium oxide or calcium oxide, which adsorbs around the lower end of the electrolytic rod. Therefore, the adsorbed potassium oxide or calcium oxide around the lower end of the electrolytic rod also needs to be cleaned.

[0003] Existing high-pressure electrolyzers for hydrogen production via water electrolysis are diverse, but they are basically used to electrolyze molten liquid to produce hydrogen and oxygen, and then collect the hydrogen and oxygen. However, this collection process can cause problems, such as hydrogen and oxygen leakage. Hydrogen leakage is particularly hazardous and requires collection and treatment. While oxygen leakage is not harmful, it is at the positive electrode and, during electrolysis, will displace potassium or calcium ions in the molten liquid, producing potassium oxide or calcium oxide, which adsorbs around the lower end of the electrolysis rod, thus affecting the conductivity of the rod's wires. Therefore, this application proposes a novel high-pressure electrolyzer for hydrogen production via water electrolysis to solve these problems. Summary of the Invention

[0012] This invention provides a high-pressure electrolyzer for hydrogen production via water electrolysis. It has the following advantages:

[0013] (1) The scraping device in this application can effectively prevent the solid substances such as potassium oxide or calcium oxide from being adsorbed on the lower outer side of the electrolytic rod during the collection of oxygen, which is the positive electrode. This affects the conductivity of the electrolytic rod. When oxygen is collected, the wind turbine will rotate. The wind turbine will transmit the rotational force to the winding wheel through the rotating rod. The winding wheel will drive the bevel gear fixedly connected in the winding groove inside to rotate. The bevel gear will mesh with the toothed rod and drive the scraper fixedly connected at the bottom of the toothed rod to move downward. At the same time as moving downward, the scraper will scrape off the solid substances such as potassium oxide or calcium oxide on the lower outer side of the electrolytic rod to prevent the solid substances such as potassium oxide or calcium oxide from affecting the conductivity of the electrolytic rod and thus affecting the entire electrolysis process. After the scraping is completed, the torsion spring inside the wind turbine will rotate in the opposite direction to drive the rotating rod, winding wheel and bevel gear to rotate in the opposite direction. The toothed rod and scraper will also return to their original positions under the action of the reverse rotation, ready for the next scraping work. (2) This application, through the setting of the alarm suction device, can effectively handle the potential rupture or leakage of the connecting pipe on the hydrogen collection side during the hydrogen collection process. The sealing pipe fixedly connected to the outside of the connecting pipe on the hydrogen side can effectively prevent hydrogen from leaking into the air and causing an explosion, thus creating a safety hazard, when the connecting pipe ruptures or leaks. A hydrogen density measuring meter is fixedly connected to the inner wall on the right side of the sealing pipe. Once the density or concentration of hydrogen exceeds the standard, the telescopic rod slidably connected to the other end of the hydrogen measuring meter will move to the right and squeeze the alarm light switch. The alarm light will then sound and notify the staff to handle the situation. At the same time, as the telescopic rod moves to the right, the rotating plate will move to the top of the connecting groove. The gravity block set above the rotating plate will cause the rotating plate to rotate due to gravity under the action of the rotating shaft. The rotation of the motor causes the gravity block to slide through the connecting groove to the bottom, pressing the motor switch. This starts the motor, causing the transmission rod to rotate. Simultaneously, the horizontal bevel gear at the bottom of the transmission rod meshes with the vertical bevel gear, causing the extension rod to rotate. The extension rod then drives the suction fan, which draws the leaked hydrogen from the sealed tube to the other end of the suction pipe. The rotation of the transmission rod also causes the small rotating rod fixedly connected to its lower end to rotate. This small rotating rod rotates and presses the slider slidingly connected to the right-side groove. The slider then presses the flame box switch along the groove, causing the flame box to spray flames from the nozzle to burn the leaked hydrogen. This process treats the leaked hydrogen, prevents safety hazards, and improves the overall practicality of the device. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figure 1-5This invention provides a technical solution: a high-pressure electrolyzer for hydrogen production by water electrolysis, comprising an electrolyzer 1, which is a sealed metal tank. The left side of the electrolyzer 1 is the positive electrode, and the right side is the negative electrode. The electrolyzer 1 is rectangular in shape. A molecular membrane 2 is fixedly connected to the central region inside the electrolyzer 1. The molecular membrane 2 is designed to allow liquid to pass through but prevent gas from passing through, thus preventing the gases from mixing. An electrolytic melt 3 is stored at the lower end of the electrolytic melt 2. An electrolytic rod 4 is fixedly mounted above the electrolytic melt 2, with a portion of the lower end of the electrolytic rod 4 submerged in the electrolytic melt 3. Two electrolytic rods 4 are provided, and the material of the electrolytic rod 4 is a metal with good conductivity. The electrolytic rod 4 is rectangular when viewed from the front. A fixing rod 5 is fixedly connected to the other end of the electrolytic rod 4. The fixing rod 5 is fixedly connected to the inner wall of the lower end of the connecting pipe 6. The lower end of the connecting pipe 6 passes through and is fixedly connected to the inner wall of the top of the electrolytic cell 1. There are two connecting pipes 6. The left connecting pipe 6 is the positive electrode, and a scraping device 7 is fixedly installed inside. The right connecting pipe 6 is the negative electrode, and an alarm suction device 10 is installed on the outside. Both connecting pipes 6 are rectangular in shape when viewed from the front. The scraping device 7 is also fixedly installed inside the connecting pipe 6. In this application, the scraping device 7 can effectively prevent oxygen from being collected. The side that collects oxygen is the positive electrode. During electrolysis, solid substances such as potassium oxide or calcium oxide will be produced and adsorbed on the outer side of the lower end of the electrolytic rod 4, thus affecting the conductivity of the electrolytic rod 4. When oxygen is collected, it will drive the wind wheel 71 to rotate. The wind wheel 71 will transmit the rotational force to the winding wheel 73 through the rotating rod 72. The winding wheel 73 will drive the bevel gear 74 fixedly connected in its inner winding groove to rotate. The bevel gear 74 will engage with the toothed rod 75. The meshing mechanism drives the scraper 76, which is fixedly connected to the bottom of the toothed rod 75, to move downwards. Simultaneously, the scraper 76 scrapes away solid substances such as potassium oxide or calcium oxide from the outer side of the lower end of the electrolytic rod 4, preventing these substances from affecting the conductivity of the electrolytic rod 4 and thus the entire electrolysis process. After scraping is complete, the torsion spring 77 inside the windmill wheel 71 rotates in the opposite direction, causing the rotating rod 72, winding wheel 73, and bevel gear 74 to rotate in the opposite direction. The toothed rod 75 and scraper 76 also return to their original positions under the action of the reverse rotation, ready for the next scraping operation. The scraping device 7 includes a windmill wheel 71, which rotates when collecting oxygen, driving the rotating rod 72 to rotate. Simultaneously, the rotating rod 72 drives the scraper 76 to scrape away the solid substances such as potassium oxide or calcium oxide adsorbed at the lower end of the electrolytic rod 4. The wind turbine wheel 71 is rotatably connected to the upper inner wall of the left connecting pipe 6 via the rotating rod 72. Six blades are arranged on the outer side of the wind turbine wheel 71. A torsion spring 77 is located between the outer side of the rotating rod 72 and the interior of the wind turbine wheel 71. The torsion spring 77 is installed inside the wind turbine wheel 71, and it can drive the wind turbine wheel 71 and the rotating rod 72 to rotate in reverse, thereby causing the scraper to reset.A rotating rod 72 is rotatably connected through the interior of the wind turbine 71. Winding wheels 73 are rotatably connected to the outer ends of both ends of the rotating rod 72. A bevel gear 74 is fixedly connected to the winding groove of the winding wheel 73. The bevel gear 74 meshes with a retaining rod 75. A scraper 76 is fixedly connected to the other end of the retaining rod 75. The scraper 76 scrapes away solid substances such as potassium oxide or calcium oxide adsorbed at the lower end of the electrolytic rod 4, preventing them from affecting the conductivity of the electrolytic rod 4. The scraper 76 is made of a corrosion-resistant and high-hardness metal. While the scraper 76 appears rectangular from the front, its actual shape is ring-shaped. The electrolytic rod 4 is slidably connected through the interior of the scraper 76. A flexible hose 8 is fixedly connected to the top of the connecting pipe 6, and a sealing pipe 9 is fixedly connected to the outside of the right side of the connecting pipe. An alarm suction device 10 is fixedly installed on the right side of the sealing pipe 9. This application can effectively handle the situation where the connecting pipe 6 on the hydrogen collection side may break or leak during the hydrogen collection process. The sealing pipe 9 fixedly connected to the outside of the hydrogen connecting pipe 6 can effectively prevent hydrogen from leaking into the air and causing an explosion, thus creating a safety hazard, when the connecting pipe 6 breaks or leaks. A hydrogen density meter 11 is fixedly connected to the inner wall of the right side of the sealing pipe 9. Once the density or concentration of hydrogen exceeds the standard, the telescopic rod 12 slidably connected to the other end of the hydrogen meter 11 will move to the right and squeeze the alarm light switch 13. The alarm light 14 will then sound an alarm and notify the staff to handle the situation. At the same time, as the telescopic rod 12 moves to the right, the rotating plate 125 will move above the connecting groove 16. The gravity block 123 set above the rotating plate 125 will be affected by gravity and rotated by the shaft 124. Rotating the turntable 125 causes the gravity block 123 to slide through the connecting groove 16 to the bottom of the groove, pressing the motor switch 71. This starts the motor 18, causing the transmission rod 19 to rotate. Simultaneously, the horizontal bevel gear 111 at the bottom of the transmission rod 19 meshes with the vertical bevel gear 112, causing the extension rod 113 to rotate. The extension rod 113 then drives the suction fan 115 to rotate, and the suction fan 115 uses the suction pipe 119 to expel hydrogen leaking into the sealed pipe 9. Gas is drawn into the other end of the suction pipe 119. As the transmission rod 19 rotates, it also drives the small rotating rod 110 fixedly connected to the lower end of the transmission rod 19 to rotate. The small rotating rod 110 rotates and compresses the slider 116 slidably connected to the right-side slide groove 117. The slider 116 then presses against the flame box switch 118 along the slide groove 117. The flame box 121 then sprays flames from the flame nozzle 122 to burn off the leaked hydrogen, thus treating the leaked hydrogen, preventing safety hazards, and improving the practicality of the entire device. The alarm suction device 10 includes a measuring instrument 11, which can measure the density or concentration of hydrogen in the air to prevent hydrogen leakage.The measuring instrument 11 is inserted through and fixedly connected to the left side of the alarm light base 15. The telescopic rod 12 is slidably connected inside the alarm light base 15. The alarm light switch 13 is fixedly connected inside the alarm light base 15. The connecting groove 16 is inserted through and fixedly connected to the lower end of the alarm light base 15. The telescopic rod 12 is inserted through and slidably connected to the right side of the measuring instrument 11. A gravity block 123 is installed inside the telescopic rod 12. A rotating plate 125 is installed at the bottom of the gravity block 123. The rotating plate 125 is rotatably connected to the inner wall of the bottom left side of the telescopic rod 12 via a rotating shaft 124. The alarm light switch 13 is fixedly installed on the right side of the telescopic rod 12. The alarm light switch 13 can sound an alarm when hydrogen leaks, notifying personnel to handle the situation. An alarm light 14 is fixedly connected to the right side of the alarm light switch 13. The alarm light 14 is fixedly connected to the right side of the alarm light base 15. A connecting groove 16 is slidably connected to the bottom of the telescopic rod 12. A motor switch 17 is fixedly installed on the inner side of the bottom of the connecting groove 16. A motor 18 is fixedly connected to the bottom of the motor switch 17. A transmission rod 19 is rotatably connected to the bottom of the motor 18. A horizontal bevel gear 111 is fixedly connected to the other end of the transmission rod 19. The horizontal bevel gear 111 meshes with a vertical bevel gear 112. An extension rod 113 is fixedly connected to the other end of the vertical bevel gear 112. An air intake fan 115 is rotatably connected to the other end of the extension rod 113. The air intake fan 115 can draw the hydrogen gas leaking from the sealed tube 9 into the other end of the air intake tube 119 for elimination. A connecting rod 114 is rotatably connected to the outer side of the middle part of the extension rod 113. The other end of the connecting rod 114 is fixedly connected to the inner wall of the suction pipe 119. A suction fan 115 is rotatably connected inside the suction pipe 119. The connecting rod 114 is fixedly connected inside the suction pipe 119. A slide groove 117 is fixedly connected to the top of the suction pipe 119. An L-shaped extension rod 120 is fixedly connected to the top of the suction pipe 119. A small rotating rod 110 is fixedly connected to the middle of the transmission rod 19. A slider 116 is provided on the right side of the transmission rod 19. The slider 116 is slidably connected above the slide groove 117. A flame box switch 118 is provided on the upper right side of the slide groove 117. The flame box switch 118 is fixedly connected to the flame box 121 via the L-shaped extension rod 120. A flame nozzle 122 is fixedly connected to the top right side of the flame box 121. The flame emitted from the flame nozzle 122 can burn off the leaked hydrogen.

[0021] In use, the electrolytic rod 4 is first energized to electrolyze the molten electrolytic liquid 3 in the electrolytic cell 1. Oxygen is produced at the positive electrode on the left and hydrogen is produced at the negative electrode on the right. Oxygen and hydrogen do not mix on the other side due to the action of the molecular membrane 2, but the molecular membrane 2 allows the molten electrolytic liquid 3 to pass through, enabling it to switch freely between the two sides for complete electrolysis and preventing incomplete electrolysis. The oxygen produced on the left side is collected by connecting a hose 8 to an oxygen storage tank. However, solid substances such as potassium oxide or calcium oxide will adsorb around the lower end of the electrolytic rod 4 at the oxygen electrolysis end, so it needs to be removed to prevent affecting the conductivity of the electrolytic rod 4. Therefore, a scraping device 7 is installed in the left connecting pipe 6. When collecting oxygen, the fan wheel 71 rotates. The rotational force is transmitted to the winding wheel 73 through the rotating rod 72. The winding wheel 73 drives the bevel gear 74 fixedly connected in the winding groove inside to rotate. The bevel gear 74 meshes with the toothed rod 75, causing the scraper 76 fixedly connected to the bottom of the toothed rod 75 to move downward. While moving downward, the scraper 76 scrapes off solid substances such as potassium oxide or calcium oxide from the outer side of the lower end of the electrolytic rod 4 to prevent the solid substances such as potassium oxide or calcium oxide from affecting the conductivity of the electrolytic rod 4, thereby affecting the entire electrolysis process. After the scraping is completed, the torsion spring 77 set inside the wind turbine wheel 71 will rotate in the opposite direction, causing the rotating rod 72, the winding wheel 73 and the bevel gear 74 to rotate in the opposite direction. The toothed rod 75 and the scraper 76 will also return to their original positions under the action of the reverse rotation, ready for the next scraping work.The hydrogen produced on the right side also needs to be collected in a hydrogen storage tank via hose 8. However, hydrogen leakage is strictly prohibited, as it could pose a significant safety hazard. Therefore, an alarm suction device 10 is installed on the outside of the right-side connecting pipe 6. In the event of a hydrogen leak, the sealing pipe 9 fixedly connected to the outside of the hydrogen connecting pipe 6 can effectively prevent hydrogen from leaking into the air and causing an explosion, thus preventing a safety hazard. A hydrogen density meter 11 is fixedly connected to the inner wall of the right side of the sealing pipe 9. If the density or concentration of hydrogen exceeds the standard, the telescopic rod 12, which is slidably connected to the other end of the hydrogen meter 11, will move to the right, pressing the alarm light switch 13. The alarm light 14 will then sound an alarm to notify personnel to handle the situation. Simultaneously, as the telescopic rod 12 moves to the right, the rotating plate 125 will move above the connecting groove 16. The gravity block 123 above the rotating plate 125 will rotate due to gravity under the action of the rotating shaft 124, thus reducing the gravity... Block 123 slides through the connecting groove 16 to the bottom of the connecting groove 16, pressing the motor switch 71. At this time, the motor 18 starts, driving the transmission rod 19 to rotate. While the transmission rod 19 rotates, the horizontal bevel gear 111 at the bottom of the transmission rod 19 meshes with the vertical bevel gear 112, thereby driving the extension rod 113 to rotate. The extension rod 113 drives the suction fan 115 to rotate, and the suction fan 115 draws the hydrogen gas leaking in the sealing tube 9 into the suction pipe 119. At the other end of 19, as the transmission rod 19 rotates, it also drives the small rotating rod 110 fixedly connected to the lower end of the transmission rod 19 to rotate. The small rotating rod 100 rotates and squeezes the slider 116 slidably connected on the right side slide groove 117. The slider 116 then squeezes the flame box switch 118 along the slide groove 117. The flame box 121 then sprays flames from the flame nozzle 122 to burn the leaked hydrogen, thus treating the leaked hydrogen, preventing safety hazards, and improving the practicality of the entire device.
