Description

Technical Field

[0001] The invention relates to the technical field of electrolyzers, in particular to an AEM electrolyzer for producing hydrogen by electrolyzing water. Background Art

[0002] AEM (anion exchange membrane) water electrolysis hydrogen production technology is a hydrogen production method based on the principle of water electrolysis. It uses anion exchange membrane as an electrolyte to produce hydrogen and oxygen by electrolyzing water. A DC voltage is applied to the anode and cathode of the electrolyzer. Water molecules receive electrons under the action of the cathode catalyst to undergo a hydrogen evolution reaction (HER), produce hydrogen and release it through the gas diffusion layer. At the same time, the hydroxide ions (OH-) produced by the hydrogen evolution reaction pass through the anion exchange membrane back to the anode, and undergo an oxygen evolution reaction (OER) under the action of the anode catalyst to produce oxygen and release it into the atmosphere or for other uses.

[0003] In the prior art, for example, the high-efficiency electrolytic cell with publication number CN202369653U includes a cell body, a support rod, blades and a waterproof generator. Four waterproof generators are evenly distributed at the bottom of the cell body, and blades are installed on the waterproof generator. The support rod is located above the blades and fixed to the wall of the cell body; the blades are made of titanium alloy, and the support rod is made of PVDF. Since the bottom of the electrolytic cell is provided with rotating blades, the mutual circulation of liquids is promoted, and the anion and cation exchange rate can be greatly accelerated during electrolysis, thereby greatly improving the electrolysis speed.

[0004] In actual use, rotating blades are set at the bottom of the electrolytic cell to promote the mutual circulation of liquids. However, in the prior art, electrolyzed water flows at the bottom of the electrolytic cell, making it difficult to achieve uniform distribution in the electrolytic cell, and easily causing the electrolyte to form a dead zone or short circuit in the electrolytic cell; and during the electrolysis process, hydrogen and oxygen are generated and enter the gas cavity, and the flow path of the gas cannot be controlled, resulting in gas accumulation in the cell body, causing the pressure to increase, thereby reducing the stability and safety of the electrolytic water hydrogen production electrolytic cell.

[0034] In the second embodiment, refer to the attached Figure 1-Figure 13On the basis of the first embodiment, in order to achieve uniform circulation of electrolyte in the electrolytic cell body 1: the flow channel assembly includes a flow guide straight pipe 63, the two ends of the flow guide straight pipe 63 respectively penetrate the inner walls of the lower arc flow channel groove plate 61 and the upper arc flow channel groove plate 62, the lower arc flow channel groove plate 61 and the upper arc flow channel groove plate 62 are mirror-distributed about the horizontal central axis of the flow guide straight pipe 63, the lower arc flow channel groove plate 61 and the upper arc flow channel groove plate 62 are overall in an arc-shaped cavity plate structure, and one end of the lower arc flow channel groove plate 61 is sealed and connected to the electrolyte outlet The outer surface of the electrolyte outlet 5 penetrates the interior of the anode plate 2, and one end of the upper arc-shaped flow channel groove plate 62 is sealed and connected with the electrolyte inlet 51, and the electrolyte inlet 51 extends to the outside of the anode plate 2; circular holes 630 are evenly opened on the inner wall of the guide straight pipe 63, and a lower bend pipe 611 is connected through the inner ring surface of the lower arc-shaped flow channel groove plate 61, and an upper bend pipe 621 is connected through the inner ring surface of the upper arc-shaped flow channel groove plate 62, and the upper bend pipe 621 and the lower bend pipe 611 are symmetrically distributed about the horizontal central axis of the guide straight pipe 63;

[0035] A lower arc flow channel plate 61 and an upper arc flow channel plate 62 are relatively distributed on the inner side of the electrolytic cell body 1. When the electrolyte is introduced into the inner cavity of the upper arc flow channel plate 62 through the electrolyte inlet 51, a part of the electrolyte falls in a water curtain shape through the upper bend pipe 621, and a part of the electrolyte is introduced into the interior of the lower arc flow channel plate 61 through the guide straight pipe 63, and is sprayed out through the circular holes 630 evenly opened on the guide straight pipe 63. In this way, the electrolyte is circulated inside the electrolytic cell body 1, avoiding the existence of dead zones that are difficult for the electrolyte to contact, improving the fluidity and distribution uniformity of the electrolyte, thereby improving the reaction rate and hydrogen production. Through such an electrolyte flow path, the electrolyte can fully flow through the electrode surface, thereby improving the electrolysis efficiency.

[0036] In Example 3, refer to the attached Figure 1-Figure 13 On the basis of the second embodiment, in order to achieve the turbulence of the electrolyte between the lower arc-shaped flow channel plate 61 and the upper arc-shaped flow channel plate 62 and promote the fluidity of the electrolyte: the turbulence component includes a connecting ring 640, which is fixedly installed at the center of the arc frame 64. The connecting ring 640 is a circular ring structure, and the inner surface of the connecting ring 640 is fixedly connected to the outer surface of the guide straight pipe 63. The inner walls of the two ends of the arc frame 64 are rotatably connected with shafts 641 respectively, and the upper outer surface of the shaft 641 is fixedly connected with a spoiler 642;

[0037] When the electrolyte flows between the lower arc flow channel plate 61 and the upper arc flow channel plate 62, the electrolyte in the inner cavity of the upper arc flow channel plate 62 flows downward due to gravity, and the electrolyte is caused to flow toward the surface of the spoiler 642 by utilizing multiple groups of upper curved tubes 621 arranged in an array. At this time, the spoiler 642 is impacted by the external electrolyte, and the rotation of the shaft 641 on the arc frame 64 is coordinated to realize the rotation of the spoiler 642, thereby realizing the disturbance of the electrolyte inside the electrolytic cell and improving the overall adaptability and scalability of the electrolytic reaction.

[0038] In the fourth embodiment, refer to the attached Figure 1-Figure 13 On the basis of the third embodiment, in order to achieve the stable discharge and efficient collection of hydrogen and oxygen generated by the electrolysis reaction: the air intake splitting assembly includes an air guide cover 71, which is a tapered bucket-shaped structure that is wide at the bottom and narrow at the top. The inner wall of the upper end of the air guide cover 71 penetrates the lower surface of the hydrogen discharge pipe 7, and an air intake cone cavity 711 is arranged inside the air guide cover 71. A guide plate 712 is fixedly installed on the inner surface of the lower end of the air intake cone cavity 711; a uniform air intake pipe 7121 is fixedly installed on the inner surface of the guide plate 712, and the uniform air intake pipe 7121 is a columnar hollow structure. An air guide hole 7122 is opened on the inner surface of the uniform air intake pipe 7121, and a split plate 7123 is fixedly installed on the inner wall of the air guide hole 7122, and the split plate 7123 is in a "M"-shaped structure;

[0039] The diffused gas generated by electrolysis rises, and the core is a conical bucket-shaped gas guide hood 71 that is wide at the bottom and narrow at the top, and its top is seamlessly connected to the hydrogen exhaust pipe 7. In the process of entering through multiple groups of gas guide hoods 71, the evenly distributed air intake pipe 7121 installed on the guide plate 712 forms a plurality of tiny channels at the bottom of the intake cone cavity 711, and the rising gas is divided by the dividing plate 7123 erected inside the gas guide hole 7122. The gas is then evenly divided and dispersed through the dividing plate 7123 in the gas guide hole 7122, effectively preventing the gas from directly erupting into the gas cavity 70 at high pressure, thereby ensuring the stability of gas emission and the balance of pressure inside the gas cavity 70, further improving the stable discharge of the formed gas, and ensuring the overall safety and stability of the electrolytic cell. At the same time, the presence of the dividing plate 7123 further refines the gas flow path, and improves the gas dispersion effect and collection efficiency.

[0040] In Example 5, refer to the attached Figure 1-Figure 13On the basis of the fourth embodiment, in order to realize the opening of the gas discharge at both ends of the hydrogen discharge pipe 7, the size of the gas discharge flow rate of the inner cavity of the gas cavity 70 is controlled: the gas cavity outlet flow opening adjustment component includes a connecting sleeve 1 72 and a connecting sleeve 2 721, the connecting sleeve 1 72 is detachably installed at both ends of the hydrogen discharge pipe 7, the outer side of the connecting sleeve 1 72 is fixedly connected to one side of the connecting sleeve 2 721, and an avoidance groove 7210 is opened on the inner wall of the upper end of the connecting sleeve 2 721, and an inner gear ring 725 is movably installed on the inner side of the avoidance groove 7210, and the outer ring surface of the inner gear ring 725 is fixedly provided with meshing teeth 7251; a support block 722 is fixedly installed on the upper surface of the connecting sleeve 1 72, and the support block 722 A motor 723 is fixedly installed on the outer surface of the motor 723, and a driving gear 724 is fixedly connected to the output shaft of the motor 723. The outer surface of the driving gear 724 meshes and rotates with the outer surface of the meshing teeth 7251. Limiting rings are respectively provided on both sides of the meshing teeth 7251. The limiting rings are respectively fixedly installed on both sides of the inner gear ring 725. The outer surfaces of the two groups of limiting rings are rotatably connected to the inner walls of the connecting sleeve 1 72 and the connecting sleeve 2 721; a driven gear 726 is meshed and rotated on the inner side of the inner gear ring 725. The central inner surface of the driven gear 726 is fixedly connected to a limiting column 7261. The outer surface of one end of the limiting column 7261 is rotatably connected to the inner wall of the connecting sleeve 1 72, and the outer surface of the limiting column 7261 is fixedly connected to an adjustment plate 727;

[0041] When it is necessary to control the opening size of the port of the hydrogen discharge pipe 7, the motor 723 is driven by controlling its output shaft to rotate and drive the driving gear 724 to rotate. In the rotating state, the driving gear 724 is adapted to mesh with the outer surface of the meshing tooth 7251, thereby realizing the rotation of the inner gear ring 725. At this time, when the inner gear ring 725 is limited and rotated, multiple groups of driven gears 726 on the inside rotate synchronously, thereby realizing the synchronous movement of multiple groups of adjustment plates 727, thereby realizing the size adjustment of the opening size of the port of the gas chamber 70. Specifically, according to Bernoulli's principle, the flow rate is inversely proportional to the cross-sectional area of ​​the pipeline. When the opening of the adjustment structure decreases, the area through which the gas passes decreases and the flow rate increases; when the opening of the adjustment structure increases, the area through which the gas passes increases and the flow rate decreases, further meeting the demand for precise control of the gas flow rate and helping to improve the stability and reliability of the entire gas processing.

[0042] In Example 6, refer to the attached Figure 1-Figure 13 Based on Example 5, a method for using an AEM water electrolysis hydrogen production electrolyzer is proposed, and the method comprises the following steps:

[0043] Step 1: A relatively distributed lower arc-shaped flow channel plate 61 and an upper arc-shaped flow channel plate 62 are arranged on the inner side of the electrolytic cell body 1, and an external suction pump is connected to the input end of the electrolyte inlet 51. After the suction pump is turned on, the electrolyte is introduced into the inner cavity of the upper arc-shaped flow channel plate 62 through the electrolyte inlet 51, and a part of the electrolyte falls in a water curtain shape through the upper curved pipe 621, and a part of the electrolyte is introduced into the interior of the lower arc-shaped flow channel plate 61 through the guide straight pipe 63, and is sprayed out through the circular holes 630 uniformly opened on the guide straight pipe 63, so that the electrolyte is circulated in the electrolytic cell body 1, avoiding the existence of a dead zone that is difficult for the electrolyte to contact, and improving the fluidity and distribution uniformity of the electrolyte;

[0044] Step 2: When the electrolyte flows between the lower arc-shaped flow channel plate 61 and the upper arc-shaped flow channel plate 62, the electrolyte in the inner cavity of the upper arc-shaped flow channel plate 62 flows downward due to gravity, and the electrolyte flows toward the surface of the spoiler 642 by using multiple groups of upper curved pipes 621 arranged in an array. At this time, the spoiler 642 is impacted by the external electrolyte, and the rotation of the shaft 641 on the arc frame 64 is coordinated to realize the rotation of the spoiler 642, thereby realizing the disturbance of the electrolyte inside the electrolytic cell;

[0045] Step 3: The electrolyte continuously reacts to generate hydrogen and is released through the gas diffusion layer 13. The diffused gas rises and enters through the multiple groups of gas guide covers 71. The evenly distributed air inlet pipes 7121 installed on the guide plate 712 form multiple small channels at the bottom of the air inlet cone cavity 711. The rising gas is divided by the dividing plate 7123 set up inside the gas guide hole 7122, and the gas is dispersed to avoid directly erupting into the gas cavity 70, causing the gas pressure inside the gas cavity 70 to be too high, and further improve the stable discharge of the formed gas;

[0046] Step 4: By controlling the motor 723 to drive, its output shaft rotates to drive the driving gear 724 to rotate. In the rotating state, the driving gear 724 is adapted to mesh with the outer surface of the meshing tooth 7251, so that the rotation of the inner gear ring 725 is realized. At this time, when the inner gear ring 725 is limited and rotated, multiple groups of driven gears 726 on the inside rotate synchronously, thereby realizing the synchronous movement of multiple groups of adjustment plates 727, so as to realize the size adjustment of the opening of the gas chamber 70 port. Specifically, according to Bernoulli's principle, the flow rate is inversely proportional to the cross-sectional area of ​​the pipeline. When the opening of the adjustment structure decreases, the area through which the gas passes decreases and the flow rate increases; when the opening of the adjustment structure increases, the area through which the gas passes increases and the flow rate decreases, which further meets the demand for precise control of the gas flow and helps to improve the stability and reliability of the entire gas processing.
