Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production by electrolyzing water, and particularly to a magnetic field-assisted hydrogen production device for electrolyzing water. Background Technique

[0002] Hydrogen energy exhibits great development potential due to its high energy density, clean and pollution-free products, and wide sources. Currently, the main industrial methods for producing hydrogen include methane steam reforming, coal gasification, and electrolyzing water. Compared with the former two, hydrogen production by electrolyzing water, especially when combined with renewable energy power generation technology, realizes zero carbon emissions throughout the production process, which is undoubtedly an important trend in the future development of the hydrogen energy industry.

[0003] For example, the Chinese patent with the publication number CN216585241 U discloses a hydrogen production device for electrolyzing water. The hydrogen production device for electrolyzing water includes an anode end plate, an anode insulating plate, an anode current collector plate, a sintered titanium mesh, a proton exchange membrane coated with a catalyst, a cathode gas diffusion layer, a cathode current collector plate, a cathode insulating plate, and a cathode end plate laminated in sequence. The anode end plate is provided with a water inlet and an oxygen outlet. An inlet water flow channel connected to the water inlet and an oxygen flow channel connected to the oxygen outlet are jointly formed on the anode insulating plate and the anode current collector plate. An anode flow field communicating the inlet water flow channel and the oxygen flow channel is provided on the side of the anode current collector plate facing the sintered titanium mesh;

[0004] However, the above scheme has the following deficiencies in our implementation process: In the above patent, the deionized pure water is roughly shunted through the setting of the anode flow field, and then the precise shunting of fluid hydrogen is realized by cooperating with the sintered titanium mesh cathode gas diffusion layer. By coating the catalyst that promotes the decomposition of water molecules on the proton exchange membrane, it is ensured that the pure water is uniformly decomposed at the proton exchange membrane. However, in existing hydrogen production devices, the exchange membrane is often set inside the device. When the exchange membrane needs to be replaced after long-term use, operators often cannot quickly remove the old exchange membrane and install the new one, and the operation is rather cumbersome. Therefore, we have developed a magnetic field-assisted hydrogen production device for electrolyzing water. Summary of the Invention

DETAILED DESCRIPTION

[0026] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-8 , the present invention provides a technical solution:

[0028] Embodiment 1:

[0029] A magnetic field-assisted electrolytic water hydrogen production device includes an anode plate 1 and a cathode plate 2. Spiral channels 23 are provided in the opposite surfaces of the anode plate 1 and the cathode plate 2. The lower end of the anode plate 1 is fixedly connected to a connecting plate 31, and the lower end of the cathode plate 2 is fixedly connected to a cross plate 3. The cross plate 3 is movably connected to the connecting plate 31. An electrolyte inlet 13 and an electrolyte outlet 12 are provided in both the anode plate 1 and the cathode plate 2. One end of the electrolyte inlet 13 and the electrolyte outlet 12 is connected to the spiral channel 23. By connecting external conduits to the electrolyte inlet 13 and the electrolyte outlet 12 in the anode plate 1 and the cathode plate 2 respectively, the power supply 10 and the magnetic field controller 8 are turned on respectively. The electrolyte enters the spiral channel 23 through the electrolyte inlet 13 and reacts with the catalyst 18, and then flows out from the electrolyte outlet 12;

[0030] A number of connecting rods 4 are fixedly connected in the cathode plate 2. A jack 20 is provided at one end of the connecting rod 4 close to the anode plate 1. Two limiting holes 32 are provided in the jack 20. A limiting mechanism is clamped in the limiting holes 32. The limiting mechanism is arranged in the anode plate 1. A liquid guiding mechanism is provided at one end of the anode plate 1 close to the cathode plate 2. The electrolyte is guided by the liquid guiding mechanism to prevent the electrolyte in the spiral channel 23 from flowing onto the surface of the electromagnetic coil 5 when the anode plate 1 and the cathode plate 2 are separated;

[0031] Electromagnetic coils 5 are sleeved outside the anode plate 1 and the cathode plate 2. The electromagnetic coils 5 generate an alternating magnetic field after being energized, and its direction is perpendicular to the coil direction. Based on the self-magnetism of oxygen, the generated oxygen is accelerated to be analyzed from the electrode surface. Two catalysts 18 are clamped between the anode plate 1 and the cathode plate 2. The catalyst 18 close to the anode plate 1 is a ferromagnetic CoFe2O4 nanomaterial, and the catalyst 18 close to the cathode plate 2 is a commercial Pt / C material. An anion exchange membrane 17 is clamped between the two catalysts 18. The anion exchange membrane 17 is a modified polyphenylene sulfide fabric composite material.

[0032] Embodiment 2:

[0033] On the basis of Embodiment 1, in order to prevent the electrolyte remaining in the spiral flow channel 23 from falling onto the surface of the electromagnetic coil 5 after the anode plate 1 and the cathode plate 2 are separated, two T-shaped connecting rods 19 are fixedly connected to one end of the connecting plate 31 close to the cross plate 3. The T-shaped connecting rods 19 are slidably connected in the first T-shaped cavity 26. The first T-shaped cavity 26 is opened in the cross plate 3. A connecting spring 27 is fixedly connected in the first T-shaped cavity 26. The other end of the connecting spring 27 is fixedly connected to the T-shaped connecting rod 19. The clamping end of the T-shaped lock block 16 disengages from the limiting hole 32. Under the elastic force of the connecting spring 27, the T-shaped connecting rod 19 moves outward along the first T-shaped cavity 26, and the outward movement of the T-shaped connecting rod 19 drives the connecting plate 31 to move;

[0034] The limiting mechanism includes a plurality of insertion rods 15. Two second T-shaped cavities 28 are opened in the outer side of the insertion rod 15. A T-shaped lock block 16 is slidably connected in the second T-shaped cavity 28. One end of the T-shaped lock block 16 close to the second T-shaped cavity 28 is fixedly connected to a pull rope 29. The end of the pull rope 29 away from the T-shaped lock block 16 passes through the insertion rod 15 and extends into the external environment, and is fixedly connected to a pull ring 7;

[0035] A support spring 30 is sleeved outside the pull rope 29. One end of the support spring 30 is fixedly connected to the T-shaped lock block 16, and the other end is fixedly connected to the second T-shaped cavity 28. The upper end of the T-shaped lock block 16 is arc-shaped. Due to the arc-shaped upper end of the T-shaped lock block 16, the T-shaped lock block 16 will be squeezed into the second T-shaped cavity 28 at this time. When the T-shaped lock block 16 moves to the position of the limiting hole 32, at this time, under the elastic force of the support spring 30, the T-shaped lock block 16 is clamped into the limiting hole 32, so that the anode plate 1 and the cathode plate 2 are installed together;

[0036] The liquid guiding mechanism includes an arc-shaped plate 21. The arc-shaped plate 21 is fixedly connected to the anode plate 1. A guiding cavity 14 is opened in the anode plate 1. Both ends of the guiding cavity 14 are connected to the external environment. An arc-shaped receiving groove 25 is opened in the cathode plate 2. The anode plate 1 drives the insertion rod 15 to disengage from the insertion hole 20, and at the same time, the arc-shaped plate 21 slides out of the arc-shaped receiving groove 25. The remaining electrolyte in the spiral flow channel 23 falls onto the upper end of the arc-shaped plate 21 and is discharged through the guiding cavity 14, preventing the electrolyte from falling onto the surface of the electromagnetic coil 5;

[0037] Two positioning screws 22 are fixedly connected to one end of the anode plate 1 close to the cathode plate 2. A fastening nut 6 is screwed on the outer side of the positioning screw 22. Two relief holes 24 are opened in one end of the cathode plate 2 close to the anode plate 1;

[0038] Terminal posts 9 are fixedly connected to the back surfaces of both the anode plate 1 and the cathode plate 2. The two terminal posts 9 are connected to a power supply 10 through a wire 11. Both ends of the electromagnetic coil 5 are also connected to a magnetic field controller 8 through a wire 11.

[0039] Working principle: When in use, the external conduits are respectively connected to the electrolyte inlets 13 and the electrolyte outlets 12 in the anode plate 1 and the cathode plate 2. The power supply 10 and the magnetic field controller 8 are respectively turned on. The electrolyte enters the spiral flow channel 23 through the electrolyte inlet 13 and reacts with the catalyst 18, and then flows out from the electrolyte outlet 12. After the power supply 10 is started, the current generated electrolyzes the electrolyte therein into hydrogen ions and hydroxide ions. The anion exchange membrane 17 is used to deliver the hydroxide ions and hydrogen ions generated by the electrolysis of water to the anode plate 1 and the cathode plate 2 respectively. The electromagnetic coil 5 generates an alternating magnetic field after being energized, and its direction is perpendicular to the coil direction based on the magnetic property of oxygen itself, thereby accelerating the evolution of the generated oxygen from the electrode surface;

[0040] When it is necessary to replace the catalyst 18 and the anion exchange membrane 17, at this time, by pulling the pull ring 7 outwards, several pull ropes 29 can be driven to move. The movement of the pull ropes 29 drives the T-shaped lock block 16 to move along the second T-shaped cavity 28. At this time, the clamping end of the T-shaped lock block 16 disengages from the limiting hole 32. Under the elastic force of the connecting spring 27, the T-shaped connecting rod 19 moves outwards along the first T-shaped cavity 26. The outward movement of the T-shaped connecting rod 19 drives the connecting plate 31 to move. At this time, the anode plate 1 drives the insertion rod 15 to disengage from the insertion hole 20, and at the same time, the arc-shaped plate 21 slides out of the arc-shaped storage groove 25. The remaining electrolyte in the spiral flow channel 23 falls onto the upper end of the arc-shaped plate 21 and is discharged through the guiding cavity 14 to prevent the electrolyte from falling onto the surface of the electromagnetic coil 5;

[0041] By unscrewing the fastening nut 6, the old catalyst 18 and the anion exchange membrane 17 can be removed. After removal, the new catalyst 18 and the anion exchange membrane 17 are passed through the positioning screw 22, and the fastening nut 6 is tightened again. At this time, the replacement of the catalyst 18 and the anion exchange membrane 17 is completed. The pulling of the anode plate 1 is released. Under the elastic force of the connecting spring 27, the anode plate 1 will come into contact with the cathode plate 2 again, and at the same time, the insertion rod 15 will be inserted into the insertion hole 20. Since the upper end of the T-shaped lock block 16 is arc-shaped, at this time, the T-shaped lock block 16 will be squeezed into the second T-shaped cavity 28. When the T-shaped lock block 16 moves to the position of the limiting hole 32, at this time, under the elastic force of the supporting spring 30, the T-shaped lock block 16 is clamped into the limiting hole 32, so that the anode plate 1 and the cathode plate 2 are installed together.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made therein without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
