[0031] Example:

[0032] like Figure 1-6 As shown, this embodiment provides a quick-detachable array-modular alkaline electrolytic cell, including an electrolytic cell frame 1 and a plurality of independent electrolytic cell module units 2, each of which has an independent tab lead-out structure.

[0033] A plurality of frame slots 3 are arranged in a matrix on the electrolytic cell frame 1, and one frame slot 3 can be adapted to install one electrolytic cell module unit 2. An electrolyte solution circulation pipe opening is arranged on the innermost side surface (i.e., the side surface extending into the innermost part of the frame slot) of the electrolytic cell module unit 2, and the electrolyte solution circulation pipe opening is composed of an anode liquid inlet 4, a cathode liquid inlet 5, an anode liquid outlet 6 and a cathode liquid outlet 7, and the anode liquid inlet 4, the cathode liquid inlet 5, the anode liquid outlet 6 and the cathode liquid outlet 7 are respectively connected to corresponding pipeline branches 8 in the frame slot 3, and the same type of connecting pipeline branches 8 are finally connected to the corresponding connecting pipeline mains on the electrolytic cell frame 1; the electrolyte solution circulation pipe opening and the corresponding connecting pipeline branch 8 are connected through a quick-release switch, and the quick-release connection design can simplify the maintenance and repair process.

[0034] The present invention adopts an array-modular design to divide the electrolytic cell into multiple independent electrolytic cell module units 2 installed in the electrolytic cell frame 1. Each electrolytic cell module unit 2 has an independent pole ear lead-out structure, which is convenient for the individual maintenance and replacement of the electrolytic cell module unit 2 and the expansion and upgrade of the entire electrolytic cell system.

[0035] In further specific embodiments, see Figure 6 The quick-release switch includes a rotary switch 9 and connecting nuts 10 respectively threadedly connected to the left and right pipe ends of the rotary switch. The types of the rotary switch 9 include gate valves, ball valves, stop valves, butterfly valves, etc. All the electrolyte solution flow pipe openings and the pipe openings of the connecting pipeline branch 8 are provided with rotating threads adapted to the connecting nuts 10. By rotating the connecting nuts 10 at both ends of the quick-release switch outward, the quick-release switch can be connected to the electrolyte solution flow pipe opening and the connecting pipeline branch 8 on the corresponding side.

[0036] During the operation of the entire system, if some components in a single electrolytic cell module unit 2 are damaged, the corresponding rotary switch 9 can be turned off first to prevent the electrolyte solution from flowing, and then the entire corresponding electrolytic cell module unit 2 can be removed for maintenance by rotating the connecting nut 10, so that the operation of other electrolytic cell module units 2 of the entire system will not be affected.

[0037] In this embodiment, the connection and disassembly between each electrolytic cell module unit 2 and the connecting pipeline branch 8 is achieved by rotating the connecting nut 10 and the rotating switch 9, making the connection and disassembly quick and easy, greatly reducing the maintenance time and labor intensity.

[0038] In a further specific embodiment, the bottom and top of the frame slot 3 are both provided with raised guide rails 11 along the length direction, and the top and bottom of the electrolytic cell module unit 2 are both provided with groove rails 12 matching the corresponding side guide rails 11, and the electrolytic cell module unit 2 is inserted into or slid out of the frame slot 3 along the guide rails 11. The design of the guide rails 11 and the groove rails 12 realizes the precise positioning and rapid installation of the electrolytic cell module unit 2.

[0039] Furthermore, a flexible clamping block 13 is provided at the outer notch of the frame slot 3 , and after the electrolytic cell module unit 2 is inserted into the frame slot 3 , the flexible clamping block 13 limits the electrolytic cell module unit 2 in the length direction.

[0040] Based on the design of a single electrolyzer module unit 2, this embodiment further proposes a rail bayonet design, so that each module unit can be quickly and accurately installed on the electrolyzer frame 1. This design not only improves the efficiency of module installation, but also ensures the stability and sealing of the entire electrolyzer system.

[0041] In a further specific embodiment, two opposite flexible card blocks 13 are provided on the upper and lower sides of the outer notch of the frame slot 3. In addition, each flexible card block 13 is designed with a guiding slope 14 at the end close to the outer side, and the electrolytic cell module unit 2 can be quickly inserted into the frame slot 3 along the guiding slope 14. When disassembling, it is necessary to press the flexible card block 13 to pull the electrolytic cell module unit 2 out of the frame slot 3.

[0042] In a further specific embodiment, a handle 15 is installed on the outermost surface of the electrolyzer module unit 2 to facilitate pushing and pulling it.

[0043] In this embodiment, the electrolytic cell module unit 2 has a handle 15 on the outside and has a groove structure (i.e., groove rails) on the top and bottom. The edge of the frame is equipped with a buckle (i.e., a flexible card block), which ensures the stability of the electrolytic cell module unit 2 in the electrolytic cell frame 1.

[0044] In a further specific embodiment, the anode tab 16 and the cathode tab 17 on the electrolytic cell module unit 2 are respectively installed on the front and back surfaces of the electrolytic cell module unit 2 by plugging and unplugging.

[0045] Specifically, the front and back surfaces of the electrolytic cell module unit are provided with a plug-in port in the form of a groove, and the corresponding pole ear has a protruding end that can be inserted into the plug-in port, and the metal with good conductivity is in close contact with the pole plate nipple. When the electrolytic cell is working, the current generated by the power supply flows into the electrode in the electrolytic cell through the pole ear, so that an electric field is formed between the electrode and the electrolyte solution. This embodiment uses a plug-in method to lead out the pole ear, which has the characteristics of convenient connection, easy maintenance, repair and replacement, and is conducive to the flexible expansion and adjustment of the array-modular electrolytic cell system.

[0046] In summary, the present invention effectively solves the pain points of existing alkaline electrolyzers in operation, maintenance and efficiency through innovative modular design and quick-release connection mechanism, and provides strong technical support for the commercial promotion of water electrolysis hydrogen production technology.
