Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology, specifically to an electrolytic water hydrogen generator. Background Technology

[0002] As a highly promising clean energy device, water electrolysis hydrogen generators are gradually coming into people's view. It is a device that decomposes water into hydrogen and oxygen through the chemical reaction of water electrolysis. Its working principle is based on the basic chemical reaction of water electrolysis: under the action of direct current, water molecules are decomposed in the electrolysis cell, hydrogen is produced at the cathode and oxygen is produced at the anode, and the two are collected and stored through a separation device.

[0003] However, existing water electrolysis hydrogen generators have certain drawbacks in use. They employ an integrated design, meaning individual components cannot be replaced or maintained independently. If a component malfunctions, the entire device must be disassembled for repair or replacement, which is not only time-consuming and labor-intensive but may also damage other components due to frequent disassembly and reassembly. Adding electrolyte to existing water electrolysis hydrogen generators requires manual operation, which can easily lead to equipment damage due to insufficient electrolyte. Existing water electrolysis hydrogen generators also have a high risk of electrolyte leakage. Furthermore, the equipment structure is not stable enough, and improper installation or long-term operation can easily cause components to loosen, affecting the normal operation of the equipment and even leading to damage or shutdown. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an electrolytic water hydrogen generator.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an electrolytic water hydrogen generator, including a bottom tank, a cover, a cathode layer, an anode layer, and a hydrogen-oxygen separation layer. A plurality of cathode layers and anode layers are alternately stacked on top of the bottom tank. The cover is placed on top of the plurality of alternately stacked cathode and anode layers. A plurality of hydrogen-oxygen separation layers are respectively arranged between a plurality of adjacent cathode and anode layers. This electrolytic water hydrogen generator adopts a modular design, and each component, such as the cathode layer, anode layer, and hydrogen-oxygen separation layer, can be independently replaced and maintained. In practical applications, the cathode and anode stacked parts can be adjusted to be vertical, which can effectively avoid upper layer bubbles and ensure that the generated gas can be more easily discharged and collected. When the cathode and anode stacked parts can be adjusted to be vertical, according to the content of this solution, adaptive adjustments need to be made to the positions of the water supply tank, cathode external connector, anode external connector, hydrogen outlet pipe, and oxygen outlet pipe.

[0006] The hydrogen-oxygen separation layer consists of a sealing frame and a diaphragm. The sealing frame has a "U"-shaped cross-section, and the diaphragm's cross-section is adapted to the inner cross-section of the sealing frame. The diaphragm is laid flat inside the sealing frame and allows ions in the liquid to pass through while blocking the passage of gases. This structural design effectively prevents hydrogen and oxygen from mixing during electrolysis, avoiding potential explosion risks. At the same time, the "U"-shaped structure of the sealing frame provides stable support for the diaphragm.

[0007] Preferably, a water supply tank is installed on the top of the cover via a support block, and a water supply pipe is vertically connected to the bottom of the water supply tank. The bottom end of the water supply pipe is connected to the top of the cover, and a valve is installed on the water supply pipe. The water supply tank is connected to the cover via the water supply pipe and is equipped with a valve, thereby realizing automatic supply and flow control of the electrolyte.

[0008] Preferably, the cathode layer includes a cathode sealing frame and a cathode electrolysis plate. The cathode sealing frame has a "U"-shaped cross-section, and the cross-sectional area of ​​the cathode electrolysis plate is smaller than the area of ​​the inner cross-section of the cathode sealing frame. The cathode electrolysis plate is horizontally fixed at the middle height inside the cathode sealing frame. An external cathode connector connected to the cathode electrolysis plate is provided on the outer side of one end of the cathode sealing frame. The anode layer includes an anode sealing frame and an anode electrolysis plate. The anode sealing frame has a "U"-shaped cross-section, and the cross-sectional area of ​​the anode electrolysis plate is smaller than the area of ​​the inner cross-section of the anode sealing frame. The anode electrolysis plate is horizontally fixed at the middle height inside the anode sealing frame. An external anode connector connected to the anode electrolysis plate is provided on the outer side of one end of the anode sealing frame. The cathode and anode layers are stacked alternately, making the electric field distribution more uniform during electrolysis and reducing energy loss. The horizontal fixing method of the cathode and anode electrolysis plates maximizes the electrolysis reaction area and improves electrolysis efficiency. This structural design not only increases the contact area of ​​the electrolysis reaction but also makes the electric field distribution more uniform.

[0009] Preferably, several cathode external connectors are located at the same end of several cathode sealing frames, and the several cathode external connectors are vertically aligned. Cathode series rods are connected through the several aligned cathode external connectors. Several anode external connectors are located at the same end of several anode sealing frames, and the several anode external connectors are vertically aligned. Anode series rods are connected through the several aligned anode external connectors. The cathode external connectors and anode external connectors are connected through the series rods, which realizes efficient current conduction, ensures stable current transmission during electrolysis, and avoids the problem of local overheating or decreased electrolysis efficiency caused by uneven current distribution. This efficient electrolysis structure design enables the equipment to produce more hydrogen and oxygen per unit time, reducing the cost of hydrogen production.

[0010] Preferably, one side of each of several cathode sealing frames is horizontally connected to a hydrogen outlet branch pipe communicating with the inside of the cathode sealing frame. The hydrogen outlet branch pipes are aligned vertically, and the ends of the hydrogen outlet branch pipes away from the cathode sealing frame are connected to a vertically upward hydrogen outlet main pipe. One side of each of several anode sealing frames is horizontally connected to an oxygen outlet branch pipe communicating with the inside of the anode sealing frame. The oxygen outlet branch pipes are aligned vertically, and the ends of the oxygen outlet branch pipes away from the anode sealing frame are connected to a vertically upward oxygen outlet main pipe. The cathode sealing frame and the anode sealing frame are respectively connected to the hydrogen outlet branch pipes and the oxygen outlet branch pipes, and the gas is collected centrally through the hydrogen outlet main pipe and the oxygen outlet main pipe. This design not only facilitates the collection and transportation of gas, but also further improves the production efficiency of hydrogen and oxygen through the synergistic effect of the multi-layer electrolysis plate. At the same time, the combination of the separating sealing frame and the diaphragm effectively prevents gas backflow and cross-contamination.

[0011] Preferably, sealing gaskets are placed between any two adjacent parts of the bottom tank, the cover, several cathode sealing frames, several anode sealing frames, and several partition sealing frames. Two ear plates are fixed to both sides of the bottom tank, the cover, several cathode sealing frames, several anode sealing frames, and several partition sealing frames. The ear plates on the bottom tank, the cover, several cathode sealing frames, several anode sealing frames, and several partition sealing frames are aligned vertically. A screw rod passes through each set of vertically aligned ear plates, and each screw rod has a nut threaded at both ends. The bottom tank, the cover, the cathode sealing frames, the anode sealing frames, and the partition sealing frames are fixed together by sealing gaskets and screw rods, forming a sealed and stable structure. This design not only prevents electrolyte leakage but also enhances the overall stability of the equipment. At the same time, the alignment design of the ear plates and screw rods makes the equipment easier to install and maintain, and also makes the connection between various components tighter, reducing the risk of equipment damage due to improper installation and improving the operating efficiency of the equipment. The fixing method of the screw rods and nuts makes the connection between various components tighter, enhancing the equipment's pressure resistance and shock resistance.

[0012] The beneficial effects of this utility model are:

Each component, such as the cathode layer, anode layer, and hydrogen-oxygen separation layer, can be replaced and maintained independently. This design greatly improves the ease of maintenance of the equipment and reduces the maintenance cost. When a cathode electrolysis plate or anode electrolysis plate fails, only the corresponding module needs to be replaced, without disassembling the entire equipment.

[0014] (2) The water electrolysis hydrogen generator described in this utility model has a water supply tank connected to the cover through a water supply pipe and equipped with a valve, which realizes automatic supply and flow control of electrolyte. This design not only reduces manual operation, but also reduces the risk of equipment damage due to insufficient electrolyte. In addition, the modular design of the whole equipment allows each component to be replaced and maintained independently, further reducing the maintenance cost of the equipment.

[0015] (3) The electrolytic water hydrogen generator described in this utility model has a cathode sealing frame and an anode sealing frame connected to a hydrogen outlet branch pipe and an oxygen outlet branch pipe, respectively, and the gas is collected centrally through the hydrogen outlet main pipe and the oxygen outlet main pipe. This design not only facilitates the collection and transportation of gas, but also further improves the efficiency of hydrogen production through the synergistic effect of the multi-layer electrolysis plates. At the same time, the combination of the separating sealing frame and the diaphragm effectively prevents gas backflow and cross-contamination, ensuring the high purity of the gas.

[0016] (4) The electrolytic hydrogen generator of the present invention is a sealed and stable structure formed by fixing the bottom pool, the cover, the cathode sealing frame, the anode sealing frame and the partition sealing frame together with sealing gaskets and screws.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-4 As shown, the water electrolysis hydrogen generator of this utility model includes a bottom tank 1, a cover 2, a cathode layer 3, an anode layer 4, and a hydrogen-oxygen separation layer 5. Several cathode layers 3 and several anode layers 4 are alternately stacked on top of the bottom tank 1. The cover 2 is placed on top of the several alternately stacked cathode layers 3 and anode layers 4. Several hydrogen-oxygen separation layers 5 are respectively placed between several adjacent cathode layers 3 and anode layers 4. This water electrolysis hydrogen generator adopts a modular design. Each component, such as the cathode layer 3, anode layer 4, and hydrogen-oxygen separation layer 5, can be replaced and maintained independently. This design greatly improves the ease of maintenance of the equipment and reduces maintenance costs. When a cathode electrolysis plate 302 or an anode electrolysis plate 402 fails, only the corresponding module needs to be replaced, without disassembling the entire equipment.

[0025] The hydrogen-oxygen separation layer 5 consists of a separation sealing frame 501 and a diaphragm 502. The separation sealing frame 501 has a "U"-shaped cross-section, and the cross-section of the diaphragm 502 is adapted to the internal cross-section of the separation sealing frame 501. The diaphragm 502 is laid flat inside the separation sealing frame 501. The diaphragm 502 allows ions in the liquid to pass through while blocking the passage of gas. This structural design effectively prevents hydrogen and oxygen from mixing during electrolysis, avoiding potential explosion risks and significantly improving the safety of the equipment. At the same time, the "U"-shaped structure of the separation sealing frame 501 provides stable support for the diaphragm 502, ensuring that it will not shift or deform during electrolysis, further enhancing the reliability of gas separation.

[0026] In one optional embodiment of this example, a water supply tank 6 is mounted on the top of the cover 2 via a support block. A water supply pipe 601 is vertically connected to the bottom of the water supply tank 6, and the bottom end of the water supply pipe 601 is connected to the top of the cover 2. A valve 602 is installed on the water supply pipe 601. The water supply tank 6 is connected to the cover 2 via the water supply pipe 601 and is equipped with the valve 602, thereby realizing automatic supply and flow control of the electrolyte. This design not only reduces manual operation but also reduces the risk of equipment damage due to insufficient electrolyte. In addition, the modular design of the entire device allows each component to be replaced and maintained independently, further reducing the maintenance cost of the equipment.

[0027] In one optional embodiment of this example, the cathode layer 3 includes a cathode sealing frame 301 and a cathode electrolysis plate 302. The cathode sealing frame 301 has a "U"-shaped cross-section. The cross-sectional area of ​​the cathode electrolysis plate 302 is smaller than the area of ​​the inner cross-section of the cathode sealing frame 301. The cathode electrolysis plate 302 is horizontally fixed at the middle height inside the cathode sealing frame 301. A cathode external connector 303 connected to the cathode electrolysis plate 302 is provided on the outer side of one end of the cathode sealing frame 301. The anode layer 4 includes an anode sealing frame 401 and an anode electrolysis plate 402. The cross-sectional area of ​​the anode sealing frame 401 is a "U"-shaped cross-section. The cross-sectional area of ​​the anode electrolysis plate 402 is smaller than the area of ​​the inner cross-section of the cathode sealing frame 301. The area of ​​the internal cross-section of the sealing frame 401 is such that the anode electrolysis plate 402 is horizontally fixed at the middle height inside the anode sealing frame 401. An anode external connector 403 connected to the anode electrolysis plate 402 is provided on the outer side of one end of the anode sealing frame 401. The cathode layer 3 and the anode layer 4 are stacked alternately, which makes the electric field distribution more uniform during electrolysis and reduces power loss. The horizontal fixing method of the cathode electrolysis plate 302 and the anode electrolysis plate 402 maximizes the electrolysis reaction area and improves the electrolysis efficiency. This structural design not only increases the contact area of ​​the electrolysis reaction, but also makes the electric field distribution more uniform, reduces power loss, and further improves the energy utilization rate.

[0028] In one optional embodiment of this example, a plurality of cathode external connectors 303 are located at the same end of a plurality of cathode sealing frames 301, and the plurality of cathode external connectors 303 are vertically aligned. A cathode series rod 10 is connected through the plurality of aligned cathode external connectors 303. A plurality of anode external connectors 403 are located at the same end of a plurality of anode sealing frames 401, and the plurality of anode external connectors 403 are vertically aligned. An anode series rod 11 is connected through the plurality of aligned anode external connectors 403. The cathode external connectors 303 and anode external connectors 403 are connected through the series rods, which realizes efficient current conduction, ensures stable current transmission during electrolysis, and avoids the problem of local overheating or decreased electrolysis efficiency caused by uneven current distribution. This efficient electrolysis structure design enables the equipment to produce more hydrogen and oxygen per unit time, reduces hydrogen production costs, and improves the economy and practicality of the equipment.

[0029] In one optional embodiment of this example, one side of each of several cathode sealing frames 301 is horizontally connected to a hydrogen outlet branch pipe 304 communicating with the inside of the cathode sealing frame 301. The several hydrogen outlet branch pipes 304 are vertically aligned, and the ends of the several hydrogen outlet branch pipes 304 away from the cathode sealing frame 301 are connected to a vertically upward hydrogen outlet main pipe 12. One side of each of several anode sealing frames 401 is horizontally connected to an oxygen outlet branch pipe 404 communicating with the inside of the anode sealing frame 401. The several oxygen outlet branch pipes 404 are vertically aligned, and the ends of the several oxygen outlet branch pipes 404 are far from the cathode sealing frame 301. One end of the anode sealing frame 401 is connected to a vertically upward oxygen outlet main pipe 13. The cathode sealing frame 301 and the anode sealing frame 401 are respectively connected to the hydrogen outlet branch pipe 304 and the oxygen outlet branch pipe 404. The gas is collected centrally through the hydrogen outlet main pipe 12 and the oxygen outlet main pipe 13. This design not only facilitates the collection and transportation of gas, but also further improves the production efficiency of hydrogen and oxygen through the synergistic effect of the multi-layer electrolysis plates. At the same time, the combination of the separator sealing frame 501 and the diaphragm 502 effectively prevents gas backflow and cross-contamination, ensuring the high purity of the gas.

[0030] In one optional embodiment of this example, sealing gaskets 14 are provided between any two adjacent pairs of the bottom pool 1, the cover 2, the plurality of cathode sealing frames 301, the plurality of anode sealing frames 401, and the plurality of partition sealing frames 501. Two ear plates 7 are fixed on both sides of the bottom pool 1, the cover 2, the plurality of cathode sealing frames 301, the plurality of anode sealing frames 401, and the plurality of partition sealing frames 501. The ear plates 7 on the bottom pool 1, the cover 2, the plurality of cathode sealing frames 301, the plurality of anode sealing frames 401, and the plurality of partition sealing frames 501 are aligned vertically. A screw 8 passes through each set of vertically aligned ear plates 7, and each screw 8 has a nut 9 threaded at both ends. The bottom pool 1, the cover 2, the cathode sealing frames 301, the anode sealing frames 401, and the partition sealing frames 501 are aligned vertically. The frame 401 and the partition sealing frame 501 are fixed together by the sealing gasket 14 and the screw 8, forming a sealed and stable structure. This design not only prevents electrolyte leakage but also enhances the overall stability of the equipment. At the same time, the alignment design of the ear plate 7 and the screw 8 makes the equipment easier to install and maintain, and also makes the connection between various components tighter, reducing the risk of equipment damage caused by improper installation, reducing equipment downtime, and improving equipment operating efficiency. The fixing method of the screw 8 and nut 9 makes the connection between various components tighter, enhancing the equipment's pressure resistance and shock resistance. This stable structural design enables the equipment to maintain good performance during long-term operation and extends the service life of the equipment.

[0031] In use, first, place the bottom tank 1 in a stable installation position, ensuring it is level and stable. Then, alternately stack the cathode layer 3 and anode layer 4 on top of the bottom tank 1 in the following order: cathode layer 3, hydrogen-oxygen separator layer 5, anode layer 4, hydrogen-oxygen separator layer 5. Place sealing gaskets 14 between the bottom tank 1, cathode sealing frame 301, anode sealing frame 401, and separator sealing frame 501 to prevent electrolyte leakage. Ensure the ear plates 7 of the cathode sealing frame 301 and anode sealing frame 401 are aligned vertically. Place the cover 2 on the topmost anode layer 4 or cathode layer 3 and secure the entire device with screws 8 and nuts 9, ensuring all components are tightly connected. Open the valve 602 at the bottom of the water supply tank 6 to allow the electrolyte to flow into the electrolytic hydrogen generator through the water supply pipe 601. The electrolyte fills the bottom tank 1, cathode sealing frame 301, anode sealing frame 401, and separator sealing frame 501. The space is designed to ensure that the electrolyte completely submerges the cathode electrolysis plate 302 and the anode electrolysis plate 402. Then, the cathode series rod 10 is connected to the negative terminal of the power supply, and the anode series rod 11 is connected to the positive terminal of the power supply, ensuring that the current can pass smoothly through the cathode electrolysis plate 302 and the anode electrolysis plate 402. The power supply is turned on, and the water molecules in the electrolyte begin to decompose under the action of the electric field. Hydrogen ions are reduced to hydrogen gas at the cathode electrolysis plate 302, and oxygen ions are oxidized to oxygen gas at the anode electrolysis plate 402. Finally, the hydrogen gas is collected upwards through the hydrogen outlet branch pipe 304 into the hydrogen outlet main pipe 12, and the oxygen gas is collected upwards through the oxygen outlet branch pipe 404 into the oxygen outlet main pipe 13. The hydrogen and oxygen are collected in their respective main pipes and transported to the gas storage tank or other equipment through pipelines. The diaphragm 502 in the hydrogen-oxygen separation layer 5 ensures that the hydrogen and oxygen do not mix during the electrolysis process, ensuring the purity and safety of the gas.
