Description

Technical Field

[0001] This invention relates to the field of hydrogen production technology, and in particular to a modular water electrolysis hydrogen production device based on wind and solar power generation. Background Technology

[0002] In the current global trend towards a green and sustainable energy transition, hydrogen production through water electrolysis, as a highly promising clean energy production technology, has received widespread attention and research. Its core principle is to use electricity to decompose water molecules into hydrogen and oxygen. The resulting hydrogen can serve as a highly efficient and clean energy carrier, applied in several important fields such as fuel cell vehicles, distributed power generation, and industrial production, providing a feasible way to reduce dependence on traditional fossil fuels and lower carbon emissions. Wind and solar power generation, including solar and wind power, with their inexhaustible, environmentally friendly advantages, have become a key energy source for providing electricity for the hydrogen production process through water electrolysis.

[0003] In the separate storage of hydrogen and oxygen, the current process requires a shutdown operation when changing storage tanks. This involves first shutting down the core electrolysis unit of the hydrogen production plant, then closing the product delivery pipeline valves, and subsequently connecting the storage tank to the main hydrogen and oxygen outlet pipelines via flexible connecting pipes. After completion, the valves and electrolysis unit are reopened to resume gas production. Firstly, this operation relies on manual intervention to sequentially perform shutdown and valve closure actions. If a valve is not fully closed, the high-pressure hydrogen-oxygen mixture maintained in the electrolysis tank will leak through the pipeline interfaces. Secondly, leaked hydrogen mixed with air can easily form an explosive mixture, and the electrolysis system has ignition sources such as electrode discharge and heating of electrical components during operation. Once explosion conditions are met, it will pose a significant safety risk to operators and equipment. In the gas-liquid separation process, existing devices mostly adopt a simple gravity sedimentation separation structure. First, the separation efficiency is significantly affected by the gas flow rate. When the electrolysis gas production rate fluctuates, the gas flow can easily carry liquid water molecules through the sedimentation area, resulting in incomplete separation. Second, the separated liquid water lacks an efficient outlet and collection mechanism. Some liquid water can easily form a wall-attached phenomenon on the inner wall of the separation chamber. Under the disturbance of the gas flow, it can be re-mixed into the gaseous products, causing the hydrogen dew point to rise. If it directly enters the subsequent purification or application system, it will cause problems such as catalyst poisoning and pipeline corrosion, which will seriously affect the operational stability of the device and the quality of hydrogen products. Summary of the Invention

[0004] Given the existing technology's problems—first, manual operation can easily lead to valves not closing, resulting in high-pressure hydrogen and oxygen leakage, and hydrogen can easily form an explosive mixture; second, the gas-liquid separation method using gravity sedimentation is greatly affected by airflow, making it difficult to extract liquid water and prone to backmixing, resulting in a high hydrogen dew point, which affects subsequent use and device stability—a modular water electrolysis hydrogen production device based on wind and solar power generation is proposed.

[0005] This application provides a modular water electrolysis hydrogen production device based on wind and solar power generation. Its purpose is to: eliminate the need to close valves when changing hydrogen or oxygen storage tanks, avoiding the risk of high-pressure gas leakage and explosion caused by manual operation; at the same time, optimize the gas-liquid separation structure, improve separation efficiency, improve liquid water output and collection, reduce hydrogen dew point, and ensure subsequent use.

[0006] The technical solution of the present invention is as follows: a modular water electrolysis hydrogen production device based on wind and solar power generation, including a base, a column is provided on one side of the top of the base, an electrolysis tank is provided on the other side of the top of the base, two gas storage tanks are symmetrically distributed on the electrolysis tank, a connecting hose is provided at the gas inlet of each of the two gas storage tanks, two bends are symmetrically distributed on the electrolysis tank, the bends are connected to the corresponding connecting hoses, and a gas-liquid separation component is provided in the bends;

[0007] The gas-liquid separation component includes a gas-liquid separation assembly disposed inside a bend, a ventilation assembly disposed on the gas-liquid separation assembly, a rotation assembly disposed on the ventilation assembly, and a telescopic assembly disposed on the gas-liquid separation assembly.

[0008] The gas-liquid separation component is used to separate the gas and liquid inside the bend and to collect the separated liquid.

[0009] The gas-liquid separation assembly includes an inner cylinder disposed inside a bend, a wire mesh demister disposed inside the inner cylinder, and multiple arc-shaped cleaning plates arranged in a ring array on the top of the wire mesh demister, with the bottom of each arc-shaped cleaning plate in contact with the top of the wire mesh demister.

[0010] Furthermore, the ventilation assembly includes a ventilation cylinder disposed inside the bend, a sealing plate being disposed on the top of the ventilation cylinder, and multiple air holes being arranged in a circular array on both the sealing plate and the ventilation cylinder.

[0011] Furthermore, the rotating assembly includes a rotating cylinder disposed on the top of the sealing plate, the rotating cylinder having a spiral groove, a guide rod disposed inside the spiral groove, and the guide rod being fixedly connected to the inner wall of the bend.

[0012] Furthermore, the telescopic assembly includes a telescopic cylinder disposed inside the ventilator, a telescopic inner rod disposed at the bottom of the telescopic cylinder, a telescopic spring disposed between the telescopic inner rod and the inner wall of the telescopic cylinder, multiple arc-shaped cleaning plates being fixedly connected to the telescopic inner rod, a drive motor disposed inside the rotating cylinder, and the output shaft of the drive motor passing through the sealing plate and the ventilator and being fixedly connected to the telescopic cylinder.

[0013] Furthermore, the gas-liquid separation component also includes a lifting assembly disposed inside the bend, a collecting assembly disposed outside the bend, and a locking assembly disposed at the bottom of the bend.

[0014] The lifting assembly includes two top rods symmetrically distributed on the inner cylinder, two wedge blocks symmetrically distributed on the venting cylinder, the top rods and the corresponding wedge blocks being slidably connected, a groove being provided on the bend, a sliding block being provided inside the groove, and a lifting spring being provided between the sliding block and the inner wall of the groove.

[0015] Furthermore, the collection assembly includes a sealing cylinder disposed on the outside of the bend, two absorbent cottons symmetrically distributed on the inside of the sealing cylinder, a sealing cap screwed to the top of the sealing cylinder, and multiple collection holes arranged in a ring array on the bend.

[0016] Furthermore, the locking assembly includes a locking cylinder disposed on the connecting hose, a ring disposed at the bottom of the bend, a vertical groove disposed on the inner cylinder, an L-shaped hole disposed on the ring, and a locking block disposed on the inner side of the locking cylinder, the locking block being slidably connected to the inner side of the vertical groove and the L-shaped hole respectively.

[0017] Furthermore, it also includes wind power generation components, which include wind turbine blades mounted on a column and a generator mounted on a base.

[0018] Furthermore, it also includes a solar power generation module, which consists of two photovoltaic panels symmetrically arranged on a column, and a battery installed on the base.

[0019] The beneficial effects of this invention are:

[0020] 1. Wind power drives a generator to convert into electricity via fan blades, while solar energy is converted into electricity through the photovoltaic effect of photovoltaic panels, forming a complementary system. Excess electricity can be stored in batteries, avoiding power outages caused by reliance on a single energy source. Compared to traditional hydrogen production devices that rely on the grid or a single new energy source, this design maximizes the use of renewable energy, reduces the consumption of fossil fuels, reduces carbon emissions, and ensures the continuous and stable operation of the electrolyzer, improving the energy efficiency and environmental friendliness of the hydrogen production process, thus aligning with the development trend of new energy hydrogen production.

[0021] 2. Liquid water is initially trapped by a wire mesh demister. An arc-shaped cleaning plate, driven by a telescopic assembly, rotates and scrapes away the accumulated liquid. A telescopic spring ensures the cleaning plate adheres closely to the wire mesh. A lifting assembly raises and lowers the vent cylinder, and a collection port switch controls the precise entry of the accumulated liquid into the absorbent cotton within the sealed cylinder. Compared to traditional gravity settling separation, this structure avoids backmixing of the accumulated liquid, significantly reduces the hydrogen dew point, and ensures the quality of subsequent use. Furthermore, the absorbent cotton can be replaced by removing the sealing cap, eliminating the need to disassemble core components, simplifying maintenance, and improving the practicality and ease of operation of the gas-liquid separation process.

[0022] 3. A safe seal is achieved through a locking assembly. The locking block slides into the L-shaped hole along the vertical groove and rotates to lock, simultaneously triggering the opening of the collection hole and the venting assembly. When replacing the gas storage tank, the locking cylinder can be disassembled by reversing it, without needing to close the switch valve. Compared to the traditional operation of changing tanks that requires closing the valve, this design avoids the problem of valves not being closed due to human error, fundamentally eliminating the risk of high-pressure hydrogen and oxygen leakage in the electrolysis tank and ensuring the safety of personnel.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Example 1, referring to Figures 1-6 This invention provides a modular water electrolysis hydrogen production device based on wind and solar power generation, comprising a base 1, a column 11 fixedly connected to one side of the top of the base 1, and an electrolysis tank 12 fixedly connected to the other side of the top of the base 1. Two gas storage tanks 13 are symmetrically distributed and snapped onto the electrolysis tank 12, and each gas storage tank 13 has a threaded connection to a connecting hose 14 at its inlet. Two bent pipes 15 are symmetrically distributed and fixedly connected to the electrolysis tank 12, and the bent pipes 15 communicate with their corresponding connecting hoses 14. The device also includes a gas-liquid separation component installed within the bent pipes 15. The gas-liquid separation component includes components installed within the bent pipes 15. The gas-liquid separation component 2 is installed inside the bend pipe 15. A ventilation component 3 is installed on the gas-liquid separation component 2. A rotating component 4 is installed on the ventilation component 3. A telescopic component 5 is also installed on the gas-liquid separation component 2. The gas-liquid separation component is used to separate the gas and liquid in the bend pipe 15 and collect the separated liquid. The gas-liquid separation component 2 includes an inner cylinder 21 rotatably connected inside the bend pipe 15. A wire mesh demister 22 is fixedly connected to the inner side of the inner cylinder 21. Multiple arc-shaped cleaning plates 23 are rotatably connected to the top of the wire mesh demister 22 in a ring array. The bottom of the multiple arc-shaped cleaning plates 23 are all in contact with the top of the wire mesh demister 22.

[0038] Specifically, the electrolyte solution in the electrolysis tank 12 undergoes an electrolytic reaction, and the generated hydrogen and oxygen enter the corresponding bends 15. At this time, the gas-liquid separation component in the bend 15 starts to operate, and the gas-liquid mixture first enters the inner cylinder 21 of the gas-liquid separation assembly 2. The inner cylinder 21 serves as the core cavity for gas-liquid separation, and the wire mesh demister 22 fixed inside plays a crucial role. When the gas-liquid mixture passes through the mesh structure of the wire mesh demister 22 under the propulsion of the airflow, the liquid water molecules in the airflow collide with the wire mesh fibers due to inertia, are trapped, and adhere to the wire mesh, thus achieving gas-liquid separation. As the separation process progresses, to avoid the accumulation of liquid water adhering to the surface of the wire mesh demister 22 and affecting the separation efficiency, multiple arc-shaped cleaning plates 23 rotate along the annular array trajectory at the top of the wire mesh demister 22. The contact movement between their bottoms and the top of the wire mesh demister 22 utilizes centrifugal force to throw the liquid water adhering to the wire mesh towards the inner wall of the inner cylinder 21. Throughout the entire gas-liquid separation process, the device does not need to shut down the connecting pipeline of the electrolysis tank 12. It not only solves the problem of valve shutdown during tank replacement in traditional equipment, but also controls the hydrogen dew point within the standard range through a multi-component collaborative gas-liquid separation mechanism, ensuring safe use in subsequent applications.

[0039] Reference Figure 5 The ventilation assembly 3 includes a ventilation cylinder 31 that is slidably connected to the inside of the bend 15 with a limiting seal. A sealing plate 32 is rotatably connected to the top of the ventilation cylinder 31. Both the sealing plate 32 and the ventilation cylinder 31 have multiple air holes 33 arranged in a ring array.

[0040] Specifically, the sealing plate 32 and the vent cylinder 31 are rotatably connected. When the sealing plate 32 rotates, the air holes 33 on the sealing plate 32 and the vent cylinder 31 overlap, allowing gas to flow normally within the bend 15. When the air holes 33 on the sealing plate 32 and the vent cylinder 31 intersect, the sealing plate 32 and the vent cylinder 31 seal the bend 15, preventing further gas flow.

[0041] Reference Figure 5 The rotating assembly 4 includes a rotating cylinder 41 fixedly connected to the top of the sealing plate 32. The rotating cylinder 41 has a spiral groove 42. A guide rod 43 is slidably connected to the inner side of the spiral groove 42. The guide rod 43 is fixedly connected to the inner wall of the bent pipe 15.

[0042] Specifically, when the ventilator 31 slides inside the bend 15, it drives the rotating cylinder 41 to slide through the sealing plate 32. Under the action of the spiral groove 42, the guide rod 43 pushes the rotating cylinder 41 to rotate, which in turn drives the sealing plate 32 to rotate. This causes the air holes 33 on the sealing plate 32 and the air holes 33 on the ventilator 31 to overlap or intersect, facilitating the flow of gas or its blocking within the bend 15.

[0043] Reference Figure 5The telescopic assembly 5 includes a telescopic cylinder 51 rotatably connected to the inside of the ventilation cylinder 31. A telescopic inner rod 52 is slidably connected to the bottom of the telescopic cylinder 51. A telescopic spring 53 is fixedly connected between the telescopic inner rod 52 and the inner wall of the telescopic cylinder 51. Multiple arc-shaped cleaning plates 23 are fixedly connected to the telescopic inner rod 52. A drive motor 54 is fixedly connected to the inside of the rotating cylinder 41. The output shaft of the drive motor 54 passes through the sealing plate 32 and the ventilation cylinder 31 and is fixedly connected to the telescopic cylinder 51.

[0044] Specifically, the drive motor 54 fixed inside the rotating cylinder 41 starts, and its output shaft passes through the sealing plate 32 and the vent 31, transmitting torque to the telescopic cylinder 51 fixedly connected to it, causing the telescopic cylinder 51 to rotate synchronously inside the vent 31. Since multiple arc-shaped cleaning plates 23 are fixedly connected to the telescopic inner rod 52, and the telescopic inner rod 52 slides at the bottom of the telescopic cylinder 51 through a limiting structure, the rotation of the telescopic cylinder 51 drives the arc-shaped cleaning plates 23 to make a circular motion along the top of the wire mesh demister 22 via the telescopic inner rod 52, achieving rotational scraping of the wire mesh surface. The telescopic inner rod 52 slides at the bottom of the telescopic cylinder 51, and under the action of the telescopic spring 53, the telescopic inner rod 52 always tends to slide outwards from the telescopic cylinder 51, ensuring that the multiple arc-shaped cleaning plates 23 always contact the top of the wire mesh demister 22. Regardless of whether the vent 31 slides upwards or downwards, the multiple arc-shaped cleaning plates 23 always contact the wire mesh demister 22.

[0045] Example 2, refer to Figure 7 This is the second embodiment of the present invention, which differs from the first embodiment in that: the gas-liquid separation component further includes a lifting assembly 6 installed inside the bend 15, a collecting assembly 7 installed on the outside of the bend 15, and a locking assembly 8 installed at the bottom of the bend 15; the lifting assembly 6 includes two top rods 61 that are symmetrically distributed and fixedly connected to the inner cylinder 21, and two wedge blocks 62 that are symmetrically distributed and fixedly connected to the vent cylinder 31. The top rods 61 are slidably connected to the corresponding wedge blocks 62. A groove is provided on the bend 15, and a sliding block 63 is slidably connected to the inside of the groove. A lifting spring 64 is fixedly connected between the sliding block 63 and the inner wall of the groove.

[0046] Specifically, when the inner cylinder 21 rotates forward, it drives the top rod 61 to rotate. The top rod 61 slides with the wedge block 62. Under the action of the wedge block 62, the vent 31 moves, causing the sliding block 63 to slide inside the groove and stretching the lifting spring 64. When the inner cylinder 21 rotates in reverse, it also drives the top rod 61 to rotate in the opposite direction. The top rod 61 and the wedge block 62 are misaligned. Under the action of the lifting spring 64, the sliding block 63 slides downward inside the groove, causing the vent 31 to slide downward.

[0047] Reference Figure 8 and Figure 9The collection component 7 includes a sealing cylinder 71 fixedly connected to the outside of the bend 15. Two absorbent cottons 72 are symmetrically inserted inside the sealing cylinder 71. A sealing cap 73 is screwed onto the top of the sealing cylinder 71. Multiple collection holes 74 are arranged in a ring array on the bend 15.

[0048] Specifically, when the arc-shaped cleaning plate 23 rotates at the top of the wire mesh demister 22, centrifugal force throws water droplets from the top of the demister 22 onto the inner wall of the bent tube 15, where they enter the absorbent cotton 72 inside the sealing cylinder 71 through the collection hole 74 for collection. When the venting cylinder 31 slides upwards, the collection hole 74 is opened, activating the gas-liquid separation component to remove water droplets from the wire mesh demister 22. When the venting cylinder 31 slides downwards, the collection hole 74 is sealed, preventing gas from flowing from the bent tube 15 into the sealing cylinder 71. By loosening the screws, the sealing cover 73 is opened, allowing the absorbent cotton 72 inside the sealing cylinder 71 to be removed for easy replacement.

[0049] Reference Figure 10 and Figure 11 The locking assembly 8 includes a locking cylinder 81 fixedly connected to the connecting hose 14, a ring 82 fixedly connected to the bottom of the bend 15, a vertical groove 83 on the inner cylinder 21, an L-shaped hole 84 on the ring 82, and a locking block 85 fixedly connected to the inner side of the locking cylinder 81. The locking block 85 is slidably connected to the inner side of the vertical groove 83 and the L-shaped hole 84 respectively.

[0050] Specifically, the locking cylinder 81 is inserted into the inner cylinder 21, allowing the locking block 85 to slide against the inner side of the vertical groove 83. The locking cylinder 81 is pushed upwards until the locking block 85 slides into the vertical section of the L-shaped hole 84. Then, the locking cylinder 81 is rotated, causing the locking block 85 to rotate and insert into the horizontal section of the L-shaped hole 84. Under the action of the vertical groove 83, the inner cylinder 21 rotates, triggering the lifting assembly 6, which opens the collecting hole 74. With the combined action of the ventilation assembly 3 and the rotating assembly 4, the ventilation assembly 3 is opened, allowing normal gas flow within the bend 15. When it is necessary to pull the locking cylinder 81 out from the bottom of the bend 15, the locking cylinder 81 is reversed, causing the locking block 85 to slide from the horizontal section of the L-shaped hole 84 to the vertical section. Under the action of the vertical groove 83, the inner cylinder 21 rotates in reverse. The locking cylinder 81 is then pulled out along the vertical groove 83. The remaining structure is the same as in Embodiment 1.

[0051] Example 3, referring to Figure 1 and Figure 2 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that it also includes a wind power generation component 9. The wind power generation component 9 includes a wind power generation fan blade 91 rotatably connected to the column 11, and a generator 92 fixedly connected to the base 1.

[0052] Specifically, when wind is present, the wind turbine blades 91 mounted on the column 11 begin to rotate under the influence of the wind. The wind turbine blades 91 are connected to the generator 92 on the base 1 via a transmission mechanism. The rotational torque of the blades is transmitted to the rotor of the generator 92, causing the rotor to cut magnetic field lines within the stator magnetic field of the generator 92. Based on the principle of electromagnetic induction, an induced electromotive force is generated inside the generator 92, which then outputs alternating current (AC). This AC is processed by the device's rectification, voltage stabilization, and energy storage system, converting it into stable direct current (DC). The electrical energy is directly supplied to the electrolysis tank 12, providing energy for the electrolysis reaction of the electrolyte solution, generating hydrogen and oxygen.

[0053] Reference Figure 1 and Figure 2 It also includes a solar power generation component 10, which includes two photovoltaic panels 101 that are symmetrically distributed and rotatably connected to a column 11, and a battery 102 that is fixedly connected to a base 1.

[0054] Specifically, the two photovoltaic panels 101 symmetrically rotated on the column 11 can flexibly adjust their orientation according to the angle of sunlight to maximize solar energy reception. The photovoltaic panels 101 convert the absorbed solar energy into direct current (DC) through the photoelectric effect. The generated DC is processed by a matching photovoltaic controller, and can be directly supplied to the electrolysis tank 12. Excess energy is stored in the battery 102 on the base 1. When sunlight is insufficient or the load demand is high, the battery 102 releases its energy to ensure a stable energy supply for the device, complementing the wind power generation components 9 and improving the energy utilization efficiency and operational continuity of the device. The remaining structure is the same as in Embodiment 2.

[0055] Based on embodiments 1-3, the working principle of this invention is as follows: Under the action of wind power, the wind turbine blades 91 on the column 11 rotate, driving the rotor of the generator 92 on the base 1 to cut magnetic field lines through the transmission mechanism. The generated alternating current is rectified and regulated to be converted into direct current. At the same time, the two photovoltaic panels 101 on the column 11 can be adjusted to maximize the reception of solar energy. Through the photoelectric effect, the solar energy is converted into direct current. Part of it is directly used for power supply, and the excess power is stored in the battery 102 to ensure the energy stability of the electrolysis process. The electrolyte solution in the electrolysis tank 12 undergoes an electrolysis reaction under the drive of electricity. The generated hydrogen and oxygen enter the corresponding bends 15 respectively. The gas-liquid separation component in the bend 15 is activated. The gas-liquid mixture first enters the inner cylinder 21, and the liquid water is intercepted by the wire mesh demister 22 to achieve preliminary separation. The drive motor 54 drives the telescopic cylinder 51 to rotate, and the telescopic inner rod 52 drives the arc-shaped cleaning plate 23 to rotate along the wire mesh demister 22 to scrape off the accumulated liquid. The telescopic spring 53 ensures that the cleaning plate is always in contact with the wire mesh. Simultaneously, the ventilation component 3 and the rotating component 4 are linked. When the ventilation cylinder 31 slides, it drives the rotating cylinder 41, which, under the action of the guide rod 43 and the spiral groove 42, causes the sealing plate 32 to rotate. The gas flow is controlled by the overlapping or staggering of the air holes 33, or by blocking or controlling the gas flow. The rotation of the inner cylinder 21 drives the top rod 61 and the wedge block 62 to slide, pushing the ventilation cylinder 31 to rise and fall, stretching or resetting the lifting spring 64. The lifting action is coordinated with the collection component 7. Liquid accumulated on the inner wall of the bend 15 enters the absorbent cotton 72 of the sealing cylinder 71 from the collection hole 74. The lifting of the ventilation cylinder 31 can control the opening and closing of the collection hole 74. The absorbent cotton 72 can be replaced by removing the sealing cover 73. The locking cylinder 81 is inserted into the inner cylinder 21, so that the locking block 85 slides into the L-shaped hole 84 along the vertical groove 83 and rotates to lock, triggering the lifting component 6 to open the collection hole 74. At the same time, the ventilation component 3 is opened to ensure gas flow. When replacing the gas storage tank 13, the locking cylinder 81 can be reversed to remove it. There is no need to shut down the switch valve of the device, avoiding the leakage risk of traditional tank replacement, and achieving safe and efficient hydrogen production.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
