[0024] See Figure 1 and Figure 2 As shown, this application proposes a box-type green hydrogen production device 100. The device includes multiple boxes, each containing different hydrogen production modules to form chambers with different functions; wherein the boxes are arranged side by side and / or stacked; and the hydrogen production modules in each box are connected to form a complete hydrogen production system.
[0025] The technical solution of this application realizes the modular design of hydrogen production unit through the box, each box can be pre-manufactured and quickly assembled on site, thereby effectively shortening the construction cycle of hydrogen production unit, reducing cost, and the box-type modular design can facilitate standardized disassembly and transportation, improving its flexibility, and is particularly suitable for scenarios that require frequent movement or temporary deployment.
[0026] In a preferred embodiment, each container adopts a container-style structure design, with standardized dimensions suitable for various transportation scenarios, facilitating rapid deployment and scheduling globally. Furthermore, each container structure utilizes high-strength materials to ensure stability in harsh environments.
[0027] The various enclosures are assembled in a side-by-side and / or stacked manner to adapt to different space conditions and hydrogen production scale requirements. For example, a side-by-side arrangement is suitable for locations with ample space, facilitating maintenance and expansion; a stacked arrangement is suitable for locations with limited space, saving floor space. Furthermore, each enclosure, based on a pre-defined assembly layout, has pre-reserved interfaces. After assembly, the hydrogen production modules can be quickly connected via these pre-reserved interfaces (including electrical and piping connections) to ensure stable system operation.
[0028] See Figure 1 and Figure 2 As shown, in some embodiments, the housing includes a first housing 10, a second housing 20, a third housing (not shown in the figures, below the fifth housing 50), a fourth housing 40, a fifth housing 50, and a sixth housing 60; the first housing 10, the second housing 20, the third housing, and the fourth housing 40 are arranged in two rows and two columns, and the fifth housing 50 and the sixth housing 60 are respectively disposed above the third housing and the fourth housing 40.
[0029] In this embodiment, six enclosures are used to construct the hydrogen production system. The first enclosure (10) to the fourth enclosure (40) form a 2×2 bottom structure, while the fifth enclosure (50) and the sixth enclosure (60) are stacked on top of this structure at two different locations. This effectively utilizes vertical space and reduces the area occupied. The hydrogen production modules within each enclosure can be arranged as follows:
[0030] The first enclosure 10 houses a monitoring system, including sensors, data acquisition devices, control units, and a display screen. This system serves as the monitoring room 110 to monitor and control the operating parameters of the entire hydrogen production process, ensuring its safety and efficiency. The second enclosure 20 houses a hydrogen production power supply, including a power quality management device, rectifier, and DC-DC converter. This converts the input electrical energy into DC power suitable for the electrolysis equipment, ensuring smooth operation. The third and fourth enclosures 40 house electrolysis equipment for producing hydrogen through water electrolysis. This equipment includes an electrolyzer and an electrolyte circulation system. The fifth and sixth enclosures 50 house purification equipment, including a cooler, dryer, and adsorption tower. This equipment removes impurities (such as water vapor, oxygen, and nitrogen) from oxygen through a series of physical and chemical processes, thereby improving the purity of the hydrogen.
[0031] Through the above design, the chamber within the first enclosure 10 serves as the monitoring room 110, the chamber within the second enclosure 20 serves as the hydrogen production power supply room 210, the chambers within the third and fourth enclosures 40 serve as the electrolysis chambers 310, and the chambers within the fifth enclosure 50 and the sixth enclosure 60 serve as the refining and purification chambers 410. It is understood that all components of the electrolytic hydrogen production system described above are conventional components of existing technology, and their connection structures and hydrogen production principles are well known to those skilled in the art and need not be elaborated upon here. Through the coordinated operation of each enclosure, the efficient operation and stable output of the hydrogen production system are ensured.
[0032] Furthermore, in this embodiment, the electrolysis chamber 310 is positioned beside the hydrogen production power supply chamber 210 and the monitoring chamber 110, and the refining and purification chamber 410 is placed above the electrolysis chamber 310. This facilitates circuit wiring and pipe connections, reduces the length of lines and pipes, and lowers energy loss. Simultaneously, the compact layout of each enclosure facilitates maintenance and repair, improving the overall reliability of the system.
[0033] The monitoring room 110 is also isolated to form a power distribution room 120, which makes full use of the space within the first enclosure 10, facilitating real-time monitoring of the power supply status by management personnel and enabling timely detection and resolution of problems. This power distribution room 120 is typically equipped with an intelligent power management system for distributing and controlling the power supply to each chamber.
[0034] In some embodiments, a seawater treatment device is also installed in the electrolysis chamber 310 and connected to the electrolysis equipment for pretreating seawater. Thus, the hydrogen production device proposed in this application can fully utilize seawater as a raw material for hydrogen production, not only enriching the source of hydrogen but also achieving effective utilization of marine resources.
[0035] Seawater treatment equipment removes impurities and salt from seawater, making it more suitable for electrolysis. Pretreatment typically includes steps such as filtration, desalination (e.g., using reverse osmosis), and pH adjustment. Pretreatment makes seawater easier to electrolyze, thus reducing energy consumption and significantly decreasing byproducts (such as chlorine) produced during electrolysis, while increasing hydrogen purity and yield.
[0036] See Figure 1 As shown, in some embodiments, the third box and the fourth box 40, as well as the fifth box 50 and the sixth box 60, are connected.
[0037] One approach is through-type design, which involves removing the side panels between two adjacent enclosures during assembly. This design, by reducing unnecessary partitions and walls, facilitates easier maintenance and repair of the equipment.
[0038] Furthermore, a ladder 115 is provided between the electrolysis chamber 310 and the refining and purification chamber 410. The ladder 115 is used for operators to move between the electrolysis chamber 310 and the refining and purification chamber 410.
[0039] Ladder 115 provides operators with a passageway from electrolysis chamber 310 to refining and purification chamber 410. This allows operators to move quickly and safely between these two areas when needed, without having to detour or traverse other areas. This helps optimize the layout of the entire hydrogen production system. By reducing unnecessary passageways and partitions, the equipment arrangement can be more compact and rational, thereby saving space and reducing costs.
[0040] The ladder 115 can be installed on the third chamber to connect the third chamber and the fifth chamber 50, or it can be installed on the fourth chamber 40 to connect the fourth chamber 40 and the sixth chamber 60. Since the third chamber and the fourth chamber 40, as well as the fifth chamber 50 and the sixth chamber 60, are all interconnected, regardless of where the ladder 115 is located, operators can easily move between the electrolysis chamber 310 and the refining and purification chamber 410.
[0041] See Figure 2 As shown, in some embodiments, the top of the enclosure corresponding to the refining and purification chamber 410 is provided with a rainproof ventilation component 114.
[0042] The primary function of the rainproof ventilation component 114 is to prevent rainwater from entering the refining and purification chamber 410, thereby protecting the internal equipment and hydrogen from moisture. In addition to rain protection, the ventilation component 114 also serves to ventilate. During the refining and purification process, some harmful gases or vapors may be generated, such as untreated waste gas or hydrogen leaks. The design of the ventilation component 114 effectively removes these harmful gases, maintaining air circulation and freshness within the refining and purification chamber 410.
[0043] Among them, the ventilation component 114 can be a louvered structure, which can both block rainwater from entering and ensure air circulation.
[0044] See Figure 1 As shown, in some embodiments, each box is provided with a first door panel 111 for opening or closing the communication environment between each box and the external environment; and a second door panel 112 is provided between the boxes for opening or closing the communication environment between adjacent boxes.
[0045] In this embodiment, the primary function of the first door panel 111 is to protect the internal environment of the enclosure from external environmental influences. By opening or closing the first door panel 111, operators can easily enter each enclosure to perform equipment installation, debugging, inspection, and maintenance. The second door panel 112 is used to open or close the communication between adjacent enclosures, allowing operators to move freely between different enclosures to connect, debug, and repair equipment, thus improving work efficiency. By rationally configuring the first door panel 111 and the second door panel 112, not only is the independence and safety of each enclosure ensured, but efficient linkage between enclosures is also achieved, further optimizing the overall operation process, reducing operation time and energy consumption, and improving the overall performance of the hydrogen production system.
[0046] See Figure 1 As shown, in some embodiments, observation windows 113 are also provided on the periphery walls of each enclosure, and may further be located on the door panel. The design of the observation windows 113 facilitates operators to monitor the operating status of the equipment inside each enclosure in real time and promptly detect abnormalities. The observation windows 113 are typically made of high-strength transparent material, which ensures good visibility while resisting the impact and corrosion of the external environment. Through the observation windows 113, operators can achieve efficient monitoring of the equipment without frequently opening the door panel, further improving the system's safety and ease of operation.
[0047] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
