Description

Technical Field

[0001] This utility model relates to the field of water electrolysis hydrogen production technology, specifically to a modular water electrolysis hydrogen production platform system that can be quickly disassembled and assembled. Background Technology

[0002] Hydrogen production via water electrolysis is a core technology in green hydrogen energy production and a key pathway to achieving clean hydrogen production. It is widely used in large-scale hydrogen production stations and distributed energy supply scenarios. Currently, large-scale hydrogen production stations generally adopt a parallel architecture of multiple electrolyzer units. By stacking these units, the hydrogen production scale is increased. The core working logic is that each electrolyzer unit simultaneously performs water electrolysis reactions, and then outputs hydrogen through a centralized pipeline and electrical system. This architecture has been widely used in large-scale hydrogen production scenarios.

[0003] However, the existing electrolyzer installation system for hydrogen production via water electrolysis has significant technical flaws. In terms of space utilization, large electrolyzer units are bulky and heavy, requiring ample maintenance clearances when arranged in parallel, resulting in a loose overall layout and excessive site area, hindering the intensive deployment of hydrogen production stations. Regarding operation and maintenance, the electrolyzer units rely on complex piping and electrical connections with the system. When a single cell malfunctions and needs repair or replacement, surrounding connecting components must be disassembled, and the unit must be removed from top to bottom using large hoisting equipment—a cumbersome and time-consuming process. In terms of system expansion, the fixed installation mode lacks flexible adjustment options. Later expansion, modification, or reconfiguration based on hydrogen production needs requires significant alterations to the original system, making operations extremely difficult.

[0004] These shortcomings can lead to a series of adverse consequences. Users bear high costs for site rental, labor maintenance, and equipment rental, and prolonged system downtime results in a significant decrease in production efficiency, impacting the stability of hydrogen supply. At the industry level, loosely distributed layouts and fixed installation models limit the large-scale, intensive development of hydrogen production stations, making it difficult to adapt to the dynamic adjustment needs of hydrogen production scale in different scenarios. With the rapid development of the global green hydrogen energy industry, the demand for space utilization, ease of operation and maintenance, and expansion flexibility in hydrogen production systems is becoming increasingly urgent. Developing integrated electrolyzer systems with rapid disassembly and replacement capabilities has become a key direction for overcoming current technological bottlenecks and promoting the efficient development of the hydrogen energy industry. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this application provides a modular, quickly detachable water electrolysis hydrogen production platform system. This system effectively solves the problems of cumbersome disassembly and assembly and difficulty in capacity expansion of traditional water electrolysis hydrogen production systems. Through modular design and hydraulic support, it achieves efficient operation and maintenance, reduces costs and increases efficiency, and is adaptable to dynamic adjustments in hydrogen production scale.

[0006] To achieve the above objectives, this utility model provides a modular, quickly detachable water electrolysis hydrogen production platform system.

[0007] The water electrolysis hydrogen production platform system includes a platform frame and multiple mobile platforms. The platform frame has a multi-layered structure, comprising at least an upper and lower layer, with each layer containing multiple modular spaces. Each mobile platform can be detachably installed within its corresponding modular space.

[0008] The mobile platform includes a load-bearing frame, a sliding module, an electrolytic cell, and hydraulic support rods. The sliding module is located at the bottom of the load-bearing frame, and the electrolytic cell is mounted on the load-bearing frame. The upper end of the hydraulic support rod is hinged to the platform frame, and the lower end is hinged to the rod fixing block of the load-bearing frame. The electrolytic cell is connected to the platform frame via a connecting hose and is electrically connected to the platform frame via wires. When the hydraulic support rods retract, the load-bearing frame moves within the modular space via the sliding module. When the hydraulic support rods extend, the load-bearing frame is partially pushed out of the modular space and tilted for support.

[0009] Preferably, there are four hydraulic support rods, which are symmetrically connected to the left and right sides of the mobile platform.

[0010] Preferably, the modular space is provided with a guide rail adapted to the sliding module, and the sliding module is a caster wheel, a set of directional wheels, or a slide rail.

[0011] Preferably, the modular spaces of the upper and lower layers of the platform framework are arranged in an m-row × n-column matrix.

[0012] Preferably, the mobile platform is a rigid metal frame structure, and an insulating layer is laid on the upper layer of the electrolytic cell support base.

[0013] Preferably, the platform frame is provided with quick-connect interfaces for connecting external pipes and cables, and the electrolytic cell is provided with a connector that matches the quick-connect interface.

[0014] Preferably, the pipeline includes an alkali circulation branch pipe, a hydrogen-side main pipe, an oxygen-side main pipe, and a alkali return main pipe. The alkali return main pipe is connected to the alkali circulation branch pipe through a alkali return branch pipe and an electrolytic cell alkali return valve.

[0015] Preferably, the alkali circulation branch pipe is equipped with a pneumatic three-way valve, an alkali flow control valve, and an electrolytic cell alkali valve. The alkali enters the electrolytic cell through the pneumatic three-way valve, the alkali flow control valve, and the electrolytic cell alkali valve. Under the action of external nitrogen and the alkali return pump, it enters the alkali return main pipe through the electrolytic cell alkali return valve and the alkali return branch pipe.

[0016] Preferably, a flow sensor for monitoring the alkali removal status of the electrolytic cell and a gas-liquid separator for separating nitrogen and alkali are provided between the alkali return collection pipe and the external interface.

[0017] Preferably, in a matrix-arranged platform framework, the modular spaces in the upper and lower layers of the same column are powered by the same set of power systems.

[0018] Compared with the prior art, the beneficial effects of this application are as follows: Firstly, in terms of technical performance, this water electrolysis hydrogen production platform system, through the synergistic effect of a mobile platform and hydraulic support rods, specifically addresses the shortcomings of existing systems where electrolyzer assembly and disassembly rely on large hoisting equipment and involve cumbersome processes. The hydraulic support rods enable the smooth extension and tilting support of the load-bearing frame. Combined with the guiding action of the sliding module and guide rails, the disassembly and assembly of the electrolyzer can be completed with a small number of personnel without complex disassembly of pipelines and electrical connections, significantly reducing system maintenance downtime and ensuring production continuity. Simultaneously, the hydraulic support rods provide stable and adjustable support loads, effectively suppressing the risk of tipping over during the movement of the electrolyzer. Combined with the rigid structure and insulation layer design of the load-bearing frame, a comprehensive safety protection system is constructed, improving the safety of operation and maintenance and the stability of equipment operation.

[0019] Secondly, from an economic perspective, the modular design gives the electrolyzer independent functional integrity, enabling standardized production, spare parts inventory management, and rapid replacement, reducing the cost of reserving dedicated spare parts. The integrated design of the pneumatic valve control system and pipeline circuits achieves automated control of the shutdown and alkali return process, reducing reliance on manual labor and optimizing the system's lifecycle operational economy from both operational efficiency improvement and labor cost control perspectives. When expanding the system, only corresponding modular space and mobile platforms need to be added, without significant modifications to the original system, significantly reducing the construction and time costs of expansion and renovation.

[0020] Furthermore, the system's matrix-style modular spatial layout and independent power supply design effectively improve site space utilization and solve the problem of loose layout in existing parallel architectures. Its modular expansion capabilities can flexibly adapt to the dynamic adjustment needs of hydrogen production scale, enabling rapid response to hydrogen production demands in different scenarios, whether in initial deployment or subsequent expansion. This system aligns with the current industry demand for large-scale and intensive development of the green hydrogen energy industry, demonstrating significant industrialization potential in scenarios such as large-scale hydrogen production stations and distributed energy replenishment, providing strong support for the efficient and flexible development of hydrogen production.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a method such as Figures 1 to 4 The modular, quickly detachable water electrolysis hydrogen production platform system shown is an example of such a system. Through the coordinated operation of its components, this system enables the rapid assembly and disassembly of the electrolyzer 15, stable operation, and automated maintenance, effectively addressing the technical bottlenecks of traditional hydrogen production systems.

[0029] The water electrolysis hydrogen production platform system includes a platform frame 10 and multiple mobile platforms 11. The platform frame 10 has a multi-layer structure, including at least an upper layer and a lower layer, with multiple modular spaces 12 in each layer. Each mobile platform 11 can be detachably installed in its corresponding modular space 12. The modular design enables the electrolyzer 15 to have independent functional integrity, allowing for standardized production and rapid replacement, and adapting to the dynamic adjustment needs of hydrogen production scale.

[0030] The mobile platform 11 includes a support frame 13, a sliding module 14, an electrolytic cell 15, and a hydraulic support rod 16. The sliding module 14 is located at the bottom of the support frame 13, and the electrolytic cell 15 is mounted on the support frame 13. The upper end of the hydraulic support rod 16 is hinged to the platform frame 10, and the lower end is hinged to the rod fixing block 17 of the support frame 13. The electrolytic cell 15 is connected to the platform frame 10 via a connecting hose 18 and is electrically connected to the platform frame 10 via a wire. When the hydraulic support rod 16 retracts, the support frame 13 moves within the modular space 12 via the sliding module 14. When the hydraulic support rod 16 extends, the support frame 13 is partially pushed out of the modular space 12 and tilted for support. When the system is running, the electrolytic cell 15 needs to be disassembled and assembled according to the following procedure: first disconnect the power and pipeline connection of the target electrolytic cell 15, then extend the hydraulic support rod 16 to push out the support frame 13 and tilt it for support, facilitating forklift lifting and transportation. During installation, the operation is reversed. The hydraulic support rod 16 retracts, which drives the load-bearing frame 13 to move into place along the modular space 12. Then, the pipes and cables are connected through the quick interface. No large hoisting equipment is required throughout the process, which greatly shortens the operation and maintenance time.

[0031] In some embodiments, four hydraulic support rods 16 are symmetrically connected to the left and right sides of the mobile platform 11. This arrangement provides a stable and adjustable support load, effectively suppressing the risk of overturning during the movement of the electrolytic cell 15, and ensuring the safety of operation and maintenance and the stability of the equipment.

[0032] In some embodiments, the modular space 12 is provided with a guide rail 19 adapted to the sliding module 14. The sliding module 14 is a caster wheel, a set of directional wheels, or a slide rail. The sliding module 14 cooperates with the guide rail 19 to realize the smooth movement of the load-bearing frame 13, reduce the frictional resistance during the assembly and disassembly process, and further improve the assembly and disassembly efficiency.

[0033] In some embodiments, the modular spaces 12 of the upper and lower layers of the platform framework 10 are arranged in an m-row × n-column matrix. The matrix layout significantly improves the utilization of site space, solves the problem of loose layout in traditional parallel architectures, and adapts to the intensive deployment requirements of large-scale hydrogen production stations.

[0034] In some embodiments, the mobile platform 11 is a rigid metal frame structure, and an insulating layer is laid on the upper layer of the support base of the electrolytic cell 15. The insulating layer can achieve electrical isolation between the electrolytic cell 15 and the supporting frame 13, avoid the risk of leakage, and ensure the safe operation of the system.

[0035] In some embodiments, the platform frame 10 is provided with a quick-connect interface for connecting external pipes and cables, and the electrolytic cell 15 is provided with a connector that matches the quick-connect interface. The pluggable and pluggable connection of the quick-connect interface and the connector simplifies the connection process of pipes and cables, and further reduces the time required for disassembling and assembling the electrolytic cell 15.

[0036] In some embodiments, the pipeline includes an alkali circulation branch pipe 20, a hydrogen-side main pipe 21, an oxygen-side main pipe 22, and an alkali return main pipe 23. The alkali return main pipe 23 is connected to the alkali circulation branch pipe 20 via an alkali return branch pipe 24 and an electrolyzer alkali return valve 25. This pipeline layout forms a complete alkali circulation loop, ensuring the stable operation of the electrolyzer 15.

[0037] In some embodiments, the alkali circulation branch pipe 20 is equipped with a pneumatic three-way valve 26, an alkali flow control valve 27, and an electrolytic cell alkali valve 28. The alkali enters the electrolytic cell 15 via the pneumatic three-way valve 26, the alkali flow control valve 27, and the electrolytic cell alkali valve 28. Under the action of external nitrogen and the alkali return pump 29, it enters the alkali return main pipe 23 via the electrolytic cell alkali return valve 25 and the alkali return branch pipe 24. The pneumatic valve control and pump body work together to automate the alkali circulation and alkali return process, significantly reducing reliance on manual labor and optimizing operational economy. The alkali flow control valve 27 can adjust the inlet flow rate according to the operating temperature and aging degree of the electrolytic cell 15. The higher the operating temperature of the electrolytic cell 15, the faster the inlet flow rate; the higher the aging degree, the faster the inlet flow rate is adjusted accordingly. When the flow rate reaches the lower limit, the alkali return and cell dismantling process is triggered.

[0038] In some embodiments, a flow sensor 30 for monitoring the alkali removal status of the electrolytic cell 15 and a gas-liquid separator 31 for separating nitrogen and alkali are provided between the alkali return collection pipe 23 and the external interface. The flow sensor 30 can accurately monitor the degree of alkali removal, ensuring that the alkali is completely discharged. The gas-liquid separator 31 can prevent nitrogen from entering the alkali return pump 29 and causing cavitation, thus extending the service life of the equipment.

[0039] When the system is running, the following procedure can be followed when disassembling and assembling the electrolytic cell 15: First, disconnect the power connection of the target electrolytic cell 15 and close the alkali flow control valve 27 before it enters the system. At the same time, change the alkali inlet path through the pneumatic three-way valve 26 to ensure that the alkali is only supplied to the non-disassembling electrolytic cell 15. Then, disconnect the valves connecting the connecting hose 18 of the target electrolytic cell 15 to the hydrogen-side manifold 21 and the oxygen-side manifold 22 (i.e., close the hydrogen outlet valve and oxygen outlet valve of the electrolytic cell 15 to be disassembled), open the electrolytic cell alkali return valve 25 and ensure that the electrolytic cell alkali valve 28 is open. Introduce nitrogen into the electrolytic cell 15 through the one-way valve located after the hydrogen outlet valve and oxygen outlet valve of the electrolytic cell 15, and push the alkali in the cell through the electrolytic cell alkali return valve 25 and the alkali return branch pipe 24 into the alkali return manifold 23. During the process, the flow sensor 30 on the alkali return collection pipe 23 is monitored to determine the degree of alkali removal from the electrolytic cell 15. After the alkali solution is completely discharged, the electrolytic cell alkali return valve 25 and the electrolytic cell alkali solution valve 28 are closed, and the connection between the electrolytic cell 15 and the platform frame 10 is disconnected. The support frame 13 is pushed out and tilted for support by extending the hydraulic support rod 16, making it easy for forklifts to lift and transport. During installation, the operation is reversed. The hydraulic support rod 16 retracts, causing the support frame 13 to move along the modular space 12 into place. Then, the pipes and cables are connected through quick interfaces. The entire process does not require large hoisting equipment, greatly shortening the operation and maintenance time.

[0040] In some embodiments, in the matrix-arranged platform frame 10, the modular spaces 12 in the upper and lower layers of the same column are powered by the same group of power systems. Furthermore, each group of power systems operates independently. This independent group power supply design ensures that maintenance or replacement of a single cell does not affect the normal operation of other columns of electrolytic cells 15, significantly improving system production continuity.

[0041] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
