Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology, specifically an anti-clogging electrolyzer device for hydrogen production by water electrolysis. Background Technology

[0002] Electrolysis of water to produce hydrogen is a technology that uses electricity to decompose water into hydrogen and oxygen. It is environmentally friendly and highly efficient, and is one of the important methods for producing green hydrogen. The electrolyzer, as the core equipment in water electrolysis for hydrogen production, directly affects the hydrogen production efficiency and system stability.

[0003] An existing patent (authorization announcement number: CN222948485U) discloses a water-to-hydrogen electrolyzer. The key technical point of the solution is that, through the setting of the detection rod and the drive assembly, when personnel need to detect electrical data at different depths inside the electrolyzer body, they can hold the drive rod and rotate the circular block to rotate it, so that the threaded cylinder moves the detection rod to extend into the electrolyzer body, which facilitates non-contact detection of electrical data at different depths of the water source.

[0004] However, the above technical solutions still have certain defects. The electrolyte contains impurities such as metal ions and particulate matter, which will deposit on the surface of the electrode or diaphragm after long-term operation, resulting in uneven local current distribution and even blockage of the flow channel. Therefore, an anti-clogging electrolyzer device for hydrogen production by water electrolysis is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging electrolyzer device for hydrogen production by water electrolysis, so as to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-clogging electrolyzer device for hydrogen production by water electrolysis includes a housing, an inlet valve on the side of the housing, an anode head and a cathode head on the top of the housing, an outlet at the bottom of the housing, a floating component to accelerate hydrogen production inside the housing, and a magnetic filter for initial filtration of the electrolyte on the side of the housing.

[0008] The floating assembly includes a drive motor fixedly mounted on the side of the housing. A bidirectional screw is fixedly mounted on the output end of the drive motor. The two threads of the bidirectional screw have opposite directions of rotation. Moving rings are respectively provided on the two sets of reverse threads.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-5 As shown, an anti-clogging electrolyzer device for hydrogen production by water electrolysis includes a housing 1, a water inlet valve 3 is provided on the side of the housing 1, an anode head 4 and a cathode head 5 are provided on the top of the housing 1, a liquid outlet 26 is provided at the bottom of the housing 1, a floating component 7 for accelerating hydrogen production is provided inside the housing 1, and a magnetic filter 2 for initial filtration of the electrolyte is provided on the side of the housing 1.

[0030] In this embodiment, during electrolysis, hydrogen and oxygen bubbles tend to accumulate on the electrode surface, forming a gas film that hinders the contact between the electrolyte and the electrode, increasing the reaction impedance. By setting the floating component 7, the liquid in the electrolyte is stirred, reducing the gas film effect and reducing consumption. At the same time, the electrolyte contains metal particles such as iron and nickel, which can deposit on the electrode or diaphragm 6, causing uneven local current distribution and even short circuits. The magnetic filter 2 can adsorb ferromagnetic impurities, preventing them from entering the electrolytic cell, improving the purity of the electrolyte, and protecting the electrode and diaphragm 6.

[0031] In one embodiment, as shown in the figure, the floating assembly 7 includes a drive motor 71 fixedly mounted on the side of the housing 1. A bidirectional screw 72 is fixedly mounted on the output end of the drive motor 71. The two threads of the bidirectional screw 72 have opposite directions of rotation. Moving rings 73 are respectively provided on the two sets of reverse threads, and a floating plate 74 is fixedly mounted on one side of the moving rings 73. A cross bar 75 is provided at the bottom of the moving rings 73. Vertical plates 76 are provided at both ends of the horizontal bar of the cross bar 75. A cleaning plate 77 is provided at the lower end of the cross bar 75. The cleaning plate 77 is connected to the lower end of the cross bar 75 by an elastic element. By starting the drive motor 71, the bidirectional screw 72 is driven to rotate. The floating plate 74 reciprocates under the drive of the bidirectional screw 72, disturbing the electrolyte and causing bubbles to quickly detach from the electrode surface, reducing the gas film effect, thereby reducing energy consumption and improving current efficiency. The structure of the cross bar 75 and the cleaning plate 77 at the bottom of the floating assembly 7 can move with the floating plate 74 to scrape the inner wall of the electrolytic cell and the diaphragm 6 to prevent impurities from depositing.

[0032] In one embodiment, as shown in the figure, the cleaning plate 77 is equipped with a cleaning brush, the bristles of which are made of polytetrafluoroethylene. The floating plate 74 is conical, with the side closer to the moving ring 73 being smaller and the side farther from the moving ring 73 being larger. The surface of the floating plate 74 is coated with a catalytic coating. The cathode head 5 and anode head 4 penetrate the housing 1 and extend into the interior of the housing 1, and the two sets of electrode heads do not touch the floating plate 74. The top of the housing 1 is provided with two sets of vent holes, one for oxygen and the other for hydrogen. The cleaning brush on the cleaning plate 77 can further remove deposits, reduce the frequency of manual maintenance, and extend the equipment life. The conical design of the floating plate 74 can form a directional liquid flow, promote electrolyte circulation, and allow the generated gas to be carried out more quickly, avoiding local gas accumulation.

[0033] Hydrogen production by water electrolysis involves passing direct current into an electrolytic cell. Water molecules are oxidized at the anode to produce oxygen and hydrogen, which then migrate through the electrolyte or proton exchange membrane to the cathode, where they are reduced to hydrogen. The gases are then discharged from the cathode and anode chambers, respectively.

[0034] In one embodiment, as shown in the figure, the magnetic filter 2 includes a gripper 22 fixedly disposed on the side of the housing 1 near the water inlet valve 3. The gripper 22 holds a cover plate 23, and the cover plate 23 is connected to the gripper 22 at the middle position by a bolt 21. A filter device 24 is disposed at the bottom of the cover plate 23. An inlet 25 is disposed on the side of the filter device 24 near the housing 1, and an outlet 26 is disposed at the bottom of the filter device 24. The inlet 25 is connected to the housing 1. The magnetic filter 2 can attract ferromagnetic substances. Impurities are removed to prevent them from entering the electrolytic cell, thus improving the purity of the electrolyte and protecting the electrodes and diaphragm 6. The filter is fixed by clamps 22 and bolts 21. By removing bolts 21, it can be quickly disassembled for cleaning or replacement, reducing downtime and improving operational stability. The magnetic filter 2 serves as the primary filter to remove large metal particles. At the same time, the filter device 24 uses a combination of neodymium magnet array and magnetic grid. A high-intensity magnetic field is arranged on the inlet 25 side to capture ferromagnetic particles, and a weak magnetic field is set on the outlet 268 side to adsorb fine paramagnetic substances.

[0035] The above embodiment discloses an anti-clogging electrolyzer device for hydrogen production by water electrolysis. In this device, by starting the drive motor 71, the bidirectional screw 72 is driven to rotate. The floating plate 74 reciprocates under the drive of the bidirectional screw 72, disturbing the electrolyte and causing bubbles to quickly detach from the electrode surface, reducing the gas film effect, thereby reducing energy consumption and improving current efficiency. The cross bar 75 and cleaning plate 77 at the bottom of the floating component 7 can move with the floating plate 74 to scrape the inner wall of the electrolyzer and the diaphragm 6. At the same time, when the electrolyte is poured in, metal particles are filtered by a magnetic filter.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
