Description

Technical Field

[0001] This invention relates to the field of hydrogen production technology through water electrolysis, and in particular to a distributed hydrogen production device. Background Technology

[0002] Electrolysis of water to produce hydrogen is a clean and efficient hydrogen production technology. Its core principle is to apply direct current to the electrolyte in the electrolyzer, causing water molecules to undergo an electrochemical reaction on the electrode surface, decomposing into hydrogen and oxygen. It is widely used in many fields such as distributed hydrogen production and industrial hydrogen production. To improve electrolysis efficiency, existing technologies usually set a rotating shaft inside the electrolyzer, with multiple stirring rods fixedly installed in a circumferential ring array on the outside of the rotating shaft. The rotating shaft drives the stirring rods to rotate, stirring the electrolyte in the electrolyzer to achieve electrolyte mixing, removal of bubbles on the electrode surface, and equalization of temperature and ion concentration in the cell, thereby improving the electrolysis reaction conditions.

[0003] However, the existing water electrolysis hydrogen production devices (i.e., structures with only a rotating shaft and stirring rod) still have many shortcomings and disadvantages in actual long-term operation. These shortcomings make it difficult to continuously and stably improve electrolysis efficiency, resulting in poor equipment operational stability. For example, the problem of impurity accumulation is prominent, severely affecting electrolysis efficiency. Even after pretreatment, the tap water used for electrolysis still contains small amounts of solid impurities such as silt, rust, and colloids. Simultaneously, the electrolysis reaction may also produce small amounts of byproduct impurities such as scale and electrode corrosion debris. In the existing technology, the rotation of the stirring rod alone can only achieve horizontal and localized vertical disturbance of the electrolyte, failing to effectively clean and disturb the bottom area of ​​the electrolytic cell. Static dead water zones easily form, especially at the bottom corners and below the rotating shaft, where the aforementioned impurities gradually deposit and accumulate, forming an impurity layer. As the operating time increases, the impurity layer will continue to thicken. On the one hand, it will hinder the full contact between the electrolyte and the bottom electrode, increase the contact resistance between the electrode and the electrolyte, and lead to increased cell voltage and increased electrolysis energy consumption. On the other hand, the accumulated impurities may also block the electrode flow channel and scratch the catalytic coating on the electrode surface, further reducing the electrolysis reaction rate. In severe cases, it may even lead to electrode short circuits, equipment failure, and significantly shorten the service life of the equipment. Summary of the Invention

[0004] Therefore, it is necessary to provide a distributed hydrogen production device that can avoid the accumulation of impurities at the bottom affecting the electrolysis efficiency, in order to address the above-mentioned technical problems.

[0005] The distributed hydrogen production device provided by this invention includes a cylindrical body and a feed inlet located at the top of the cylindrical body, and further includes: Electrode tubes are installed on the inner wall of the bottom of the cylinder; A rotating cylinder is rotatably installed inside the cylinder body; Multiple stirring rods are installed in a circular array from top to bottom on the outside of the rotating cylinder. The impeller is movably mounted on the outside of the rotating cylinder; A lifting assembly is mounted on the rotating cylinder and is used to drive the impeller to move up and down.

[0006] In one embodiment, the lifting assembly includes a vertical groove, which is formed on one side of the rotating cylinder at a lower position. A lifting block is movably installed in the vertical groove, and a connecting rod is fixedly installed on one side of the lifting block. The end of the connecting rod away from the lifting block is fixedly connected to one side of the impeller.

[0007] In one embodiment, a vertical rod is movably arranged inside the rotating cylinder, the bottom of the vertical rod is fixedly connected to the inner wall of the bottom of the cylinder, a curved groove is formed on the cylinder, a limit rod is provided at one end of the lifting block near the fixed rod, and the end of the limit rod away from the lifting block is slidably embedded in the curved groove.

[0008] In one embodiment, the impeller has through holes, and the number of through holes is set to multiple.

[0009] In one embodiment, the impeller is hollow inside, and a fixing ring is fixedly installed at the through hole. The hollow part in the middle of the fixing ring coincides with the through hole. Sliding grooves are symmetrically opened on both sides of the fixing ring, and baffles are slidably installed in the sliding grooves.

[0010] In one embodiment, a rotating ring is rotatably mounted on the top of the fixed ring, and arc-shaped grooves are symmetrically formed on both sides of the rotating ring. A positioning rod is fixedly mounted on the top of the baffle and is slidably connected to the arc-shaped groove. An annular groove is formed on the top of the rotating ring, and a torsion spring is provided in the annular groove. The top of the torsion spring is fixedly connected to the inner wall of the impeller.

[0011] In one embodiment, a movable plate is fixedly installed at one end of the rotating ring, and a slot is opened inside the lifting block. A movable rod is movably installed laterally inside the slot. One end of the movable rod movably passes through the inner wall of the slot and the connecting rod, and the other end is located inside the impeller. An abutment rod is connected to the end of the movable rod, and the abutment rod movably abuts against the movable plate.

[0012] In one embodiment, a positioning plate is fixedly installed inside the slot, a round rod is rotatably installed at the bottom of the positioning plate, a cam is fixedly sleeved on the outside of the round rod, a movable frame is movably sleeved on the outside of the cam, one side of the movable frame is fixedly connected to the movable rod, a moving rod is fixedly installed at the other end of the movable frame, a positioning sleeve is movably sleeved on the outside of the moving rod, and the positioning sleeve is fixedly connected to the inner wall of the slot.

[0013] In one embodiment, a crossbar is rotatably mounted inside the slot on one side of the round rod. The crossbar and the round rod are connected by a bevel gear transmission. A drive gear is movably engaged on one side of the crossbar. A ring is fixedly connected to one side of the drive gear. Multiple slots are arranged in an annular array on the ring.

[0014] In one embodiment, racks are provided on both the upper and lower sides of the vertical groove, the racks are slidably connected to the lifting block, and the drive gear meshes with the racks for transmission.

[0015] The aforementioned distributed hydrogen production device, through the cooperation of vertical troughs, lifting blocks, and connecting rods, drives the impeller to rotate synchronously with the rotating cylinder while simultaneously moving up and down reciprocatingly, forming a combined flow field of swirling and vertical pulses. This comprehensively and thoroughly disturbs the electrolyte at the bottom of the cylinder, completely eliminating static dead water zones at the bottom corners of the electrolytic cell and below the rotating components. The through-holes on the impeller, through the cooperation of structures such as fixed rings, baffles, and rotating rings, achieve dynamic aperture adjustment as the impeller rises and falls, effectively suppressing bubble generation and promoting bubble coalescence, further improving electrolysis efficiency. Through the racks distributed vertically and horizontally on both sides of the vertical trough, in conjunction with transmission components such as drive gears, crossbars, bevel gears, and cams, the drive gears maintain a counterclockwise rotation trend, precisely controlling the opening and closing timing of the baffles, ensuring the regular movement of the through-holes as the impeller rises and as it falls.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0024] The following is combined with Figures 1-8 The distributed hydrogen production apparatus of the present invention is described.

[0025] like Figures 1-4 As shown, the distributed hydrogen production device includes a cylinder 1 with a feed inlet at the top for introducing pretreated tap water into the cylinder 1 to provide raw materials for the water electrolysis hydrogen production reaction. An electrode tube 2 is installed on the inner wall of the bottom of the cylinder 1. The electrode tube 2 can be arranged in a coiled structure to fit the inner wall of the bottom of the cylinder 1, increasing the contact area with the electrolyte and providing a stable reaction site for water molecule decomposition. At the same time, it is connected to direct current to drive the electrolysis reaction to continue.

[0026] A rotating cylinder 4 is rotatably installed inside the cylinder 1. The rotating cylinder 4 can rotate circumferentially inside the cylinder 1 around its own axis. Multiple stirring rods 3 are installed in a ring array from top to bottom on the outside of the rotating cylinder 4. The stirring rods 3 rotate synchronously with the rotating cylinder 4 to agitate the electrolyte inside the cylinder 1. On the one hand, this promotes a uniform distribution of temperature and ion concentration inside the electrolyte, eliminating concentration polarization and temperature polarization. On the other hand, it helps to strip away hydrogen and oxygen bubbles generated on the surface of the electrode tube 2, preventing bubbles from accumulating on the electrode surface to form a gas film, which would affect the efficiency of the electrolysis reaction.

[0027] See Figure 2 and Figure 3 As shown, an impeller 5 is movably installed on the outside of the rotating cylinder 4. The impeller 5 can move up and down relative to the rotating cylinder 4 and rotate together with the rotating cylinder 4. The impeller 5 is set to enhance the disturbance of the electrolyte at the bottom of the cylinder 1, completely break the static dead water zone at the bottom, prevent impurities from accumulating at the bottom, and promote full contact between the bottom electrode and the electrolyte to improve the stability of the electrolysis reaction.

[0028] The rotating cylinder 4 is equipped with a lifting component 6, which drives the impeller 5 to move up and down, so that the impeller 5 can simultaneously complete reciprocating lifting and lowering during rotation, forming a flow field that combines swirling flow and vertical pulse, further optimizing the stirring effect.

[0029] See Figure 2 and Figure 3 As shown, specifically, the lifting assembly 6 includes a vertical groove 61, which is located on one side of the rotating cylinder 4 at a lower position. The vertical groove 61 extends along the axial direction of the rotating cylinder 4. A lifting block 62 is movably installed in the vertical groove 61. The lifting block 62 can slide up and down along the length of the vertical groove 61. A connecting rod 63 is fixedly installed on one side of the lifting block 62. The end of the connecting rod 63 away from the lifting block 62 is fixedly connected to one side of the impeller 5. When the lifting block 62 moves up and down along the vertical groove 61, the connecting rod 63 can drive the impeller 5 to move up and down synchronously, realizing the linkage movement between the impeller 5 and the lifting block 62.

[0030] See Figure 2 and Figure 3 As shown, a vertical rod 7 is movably installed inside the rotating cylinder 4. The bottom of the vertical rod 7 is fixedly connected to the inner wall of the bottom of the cylinder 1. The vertical rod 7 remains stationary, and the rotating cylinder 4 can rotate circumferentially around the axis of the vertical rod 7. A curved groove 71 is provided on the vertical rod 7. The curved groove 71 has a continuous wave-shaped or spiral structure. A limit rod 8 is provided at one end of the lifting block 62 near the vertical rod 7. The end of the limit rod 8 away from the lifting block 62 is slidably embedded in the curved groove 71. When the rotating cylinder 4 rotates around the vertical rod 7, the limit rod 8 slides in the curved groove 71. The contour structure of the curved groove 71 will drive the limit rod 8 to move up and down vertically, thereby driving the lifting block 62 to slide up and down synchronously along the vertical groove 61, and finally realizing the up and down reciprocating movement of the impeller 5. The whole process does not require additional power drive and is realized by mechanical structure linkage. The structure is simple and the operation is stable.

[0031] See Figures 3-6 As shown, multiple through holes 51 are evenly distributed on the impeller 5 to conduct electrolyte between the upper and lower sides of the impeller 5, balance the fluid pressure difference between the two sides of the impeller 5, suppress the occurrence of local negative pressure cavitation, reduce the generation of new bubbles, and also preliminarily coalesce the passing micro bubbles, which facilitates the subsequent bubbles to rise and break. The impeller 5 is hollow inside, and a fixing ring 9 is fixedly installed inside the impeller 5 at the through hole 51. The hollow part in the middle of the fixing ring 9 coincides with the through hole 51 to ensure that the electrolyte can pass through smoothly. Sliding grooves 91 are symmetrically opened on both sides of the fixing ring 9. The sliding grooves 91 extend radially along the fixing ring 9. A baffle 11 is slidably installed in the sliding groove 91. The baffle 11 can slide back and forth along the sliding groove 91. By adjusting the position of the baffle 11, the conducting cross-sectional area of ​​the through hole 51 can be changed, so as to realize the dynamic adjustment of the diameter of the through hole 51.

[0032] See Figure 5 and Figure 6 As shown, a rotating ring 10 is rotatably mounted on the top of the fixed ring 9. The rotating ring 10 can rotate circumferentially around the axis of the fixed ring 9. Arc-shaped grooves 101 are symmetrically formed on both sides of the rotating ring 10, and are inclined, extending circumferentially along the rotating ring 10. A positioning rod 12 is fixedly mounted on the top of the baffle 11. The end of the positioning rod 12 away from the baffle 11 is slidably connected within the arc-shaped groove 101. When the rotating ring 10 rotates, the arc-shaped groove 101, through the positioning rod 12, drives the baffle 11 to slide along the groove. The moving groove 91 slides back and forth, thereby adjusting the degree of obstruction of the through hole 51 by the baffle 11, and realizing the scaling of the diameter of the through hole 51; the top of the rotating ring 10 is provided with an annular groove 102, and a torsion spring 13 is provided in the annular groove 102. The top of the torsion spring 13 is fixedly connected to the inner wall of the impeller 5. The torsion spring 13 is used to provide a reset elastic force for the rotating ring 10, so that the rotating ring 10 can return to the initial position when there is no external force, ensuring the stability of the initial position of the baffle 11, and thus maintaining the initial diameter state of the through hole 51.

[0033] See Figures 5-7 As shown, a movable plate 14 is fixedly installed at one end of the rotating ring 10. The movable plate 14 rotates synchronously with the rotating ring 10. A slot 621 is opened inside the lifting block 62. The slot 621 extends laterally along the lifting block 62. A movable rod 15 is movably installed laterally inside the slot 621. The movable rod 15 can slide back and forth along the length of the slot 621. One end of the movable rod 15 moves through the inner wall of the slot 621 and the connecting rod 63, and the end extends into the impeller 5. The end of the connecting rod 63 is connected to an abutment rod 16. The abutment rod 16 moves in contact with the movable plate 14. When the movable rod 15 slides back and forth, it will drive the abutment rod 16 to move synchronously. The abutment rod 16 presses against or releases the movable plate 14, thereby driving the movable plate 14 and the rotating ring 10 to rotate, realizing the sliding adjustment of the baffle 11.

[0034] See Figures 5-7 As shown, a positioning plate 17 is fixedly installed inside the slot 621. A round rod 18 is rotatably installed at the bottom of the positioning plate 17. The round rod 18 can rotate around its own axis. A cam 19 is fixedly sleeved on the outside of the round rod 18. A movable frame 20 is movably sleeved on the outside of the cam 19. The movable frame 20 fits against the outer peripheral wall of the cam 19. When the cam 19 rotates, the change in the contour of the cam 19 will drive the movable frame 20 to move laterally back and forth. One side of the movable frame 20 is fixedly connected to the movable rod 15. A moving rod 21 is fixedly installed at the other end of the movable frame 20. A positioning sleeve 22 is movably sleeved on the outside of the moving rod 21. The positioning sleeve 22 is fixedly connected to the inner wall of the slot 621. The positioning sleeve 22 is used to guide and limit the moving rod 21 to ensure that the reciprocating movement of the movable frame 20 and the movable rod 15 is smooth and accurate, and to avoid deviation or jamming.

[0035] See Figures 5-8As shown, a crossbar 23 is rotatably mounted inside the slot 621 on one side of the round rod 18. The crossbar 23 can rotate around its own axis. The crossbar 23 and the round rod 18 are connected by a bevel gear 24. The bevel gear 24 enables the power transmission between the crossbar 23 and the round rod 18, so that when the crossbar 23 rotates, it can drive the round rod 18 to rotate synchronously. When the impeller 5 moves from bottom to top relative to the rotating cylinder 4, in the initial state, the baffles 11 on both sides move away from each other and do not block the through hole 51. The through hole 51 is in the maximum aperture state. At this time, the liquid can quickly flow down from the through hole 51, instantly balancing the negative pressure at the bottom of the impeller 5, effectively suppressing the occurrence of cavitation, avoiding the generation of new bubbles, and ensuring the stable progress of the electrolysis reaction.

[0036] When the lifting block 62 moves to the top of the vertical groove 61 with the rotating cylinder 4, the drive gear 25 meshes with the rack 29 at the top of the vertical groove 61. The rack 29 drives the drive gear 25 to rotate counterclockwise. In this direction of rotation, the locking block 27 and the locking groove 261 of the ring 26 are in a stable locking state. The drive gear 25 will drive the crossbar 23 to rotate synchronously. After the crossbar 23 rotates, it drives the round rod 18 to rotate through the bevel gear 24. The rotation of the round rod 18 further drives the cam 19 to rotate. The change in the contour of the cam 19 pushes the movable frame 20. Moving closer to the connecting rod 63, the movable frame 20 drives the movable rod 15 to move towards the inside of the impeller 5. The movable rod 15 pushes the abutment rod 16 to move synchronously. The abutment rod 16 presses against the movable plate 14, causing the movable plate 14 and the rotating ring 10 to rotate counterclockwise. The torsion spring 13 is twisted and stores elastic force. During the rotation of the rotating ring 10, the two baffles 11 move closer to each other through the arc groove 101 and the positioning rod 12, blocking the through hole 51 and making the diameter of the through hole 51 smaller. At this time, the through hole 51 is in a reduced state.

[0037] Subsequently, the lifting block 62 begins to move downwards, and the drive gear 25 meshes with the rack 29 again. At this time, the rack 29 drives the drive gear 25 to rotate clockwise. In this direction of rotation, the locking block 27 disengages from the locking groove 261 of the ring 26, and the locking block 27 compresses the spring 28. The rotation of the drive gear 25 will not drive the crossbar 23 to rotate together. The baffle 11 remains in a position close to the through hole 51, that is, it keeps the diameter of the through hole 51 decreasing as it moves downwards with the impeller 5. The decrease in the diameter of the through hole 51 plays a throttling and damping role, reducing the impact and fluctuation of the liquid during the downward pressing of the impeller 5. At the same time, it squeezes and coalesces the microbubbles passing through the through hole 51, so that the microbubbles merge into large bubbles, which facilitates the subsequent rapid floating and collapse, reduces the number of suspended fine bubbles in the tank, and reduces the obstruction of the electrolysis reaction by the bubbles.

[0038] When the lifting block 62 drives the drive gear 25 to engage with the rack 29 at the bottom of the vertical groove 61, the rack 29 drives the drive gear 25 to rotate counterclockwise again. In this direction of rotation, the locking block 27 re-engages with the locking groove 261 of the ring 26, and the crossbar 23 rotates synchronously with the drive gear 25, driving the round rod 18 and cam 19 to rotate through the bevel gear 24. After the cam 19 rotates, it drives the movable frame 20 to move away from the connecting rod 63. The movable frame 20 pulls the movable rod 15 and the abutment rod 16 to move in the opposite direction. The abutment rod 16 disengages from the limit on the movable plate 14. At this time, the movable plate 14 and the rotating ring 10 rotate clockwise under the restoring force of the torsion spring 13, causing the baffles 11 on both sides to move away from each other, completely exposing the through hole 51, and the through hole 51 returns to its maximum diameter state.

[0039] Subsequently, the lifting block 62 moves upward again, the drive gear 25 meshes with the rack 29 at the top of the vertical groove 61 and rotates clockwise. When rotating in this direction, the locking block 27 and the locking groove 261 do not engage, the drive gear 25 does not drive the crossbar 23 to rotate, the baffles 11 remain in a state of being far apart from each other, and the through hole 51 maintains its maximum diameter as it moves upward with the impeller 5. After that, all the above actions are repeated to achieve synchronous linkage between the up and down movement of the impeller 5 and the scaling of the through hole 51.

[0040] The racks 29 on the upper and lower sides of the vertical groove 61 are respectively arranged on the left and right sides of the vertical groove 61 and distributed vertically. Through the arrangement direction of the racks 29, the drive gear 25 maintains a counterclockwise rotation trend as it moves up and down with the lifting block 62. This results in the regular action that when the lifting block 62 rises, the baffles 11 move away from each other and the through hole 51 becomes larger; when the lifting block 62 falls, the baffles 11 move closer to each other and the through hole 51 becomes smaller. Through this dynamic linkage structure, the flow field at the bottom of the cylinder 1 is continuously optimized, effectively suppressing bubble generation, coalescing microbubbles, and preventing impurity accumulation, thus significantly improving the efficiency of hydrogen production by water electrolysis and the stability of the device operation.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
