Description

Technical Field

[0001] This utility model relates to the field of hydrogen production equipment technology, specifically to a large-capacity electrolyzer hydrogen production container. Background Technology

[0002] Hydrogen is the cleanest and most efficient energy source of the 21st century, with water as its only byproduct. It is a crucial pathway to achieving renewable energy conversion and carbon neutrality. Therefore, technological research surrounding hydrogen energy has gained increasing attention in recent years. Hydrogen production technology, as the upstream technology of the entire hydrogen energy industry chain, has become a key link in the development of the hydrogen energy industry. Among all hydrogen production technologies, alkaline water electrolysis has an early start, high technological maturity, and low cost, consistently maintaining its dominant position in my country's hydrogen production technology.

[0003] Alkaline electrolyzers are the main equipment in alkaline water electrolysis for hydrogen production. With market development and technological maturity, the size and weight of alkaline electrolyzers have become increasingly large, with some reaching 50 tons per 1000 cubic meter. This has led to significant difficulties in the assembly, transportation, and maintenance of these electrolyzers. Furthermore, the electrolyzers generate a large amount of heat during operation, and such a large tank is difficult to dissipate heat within traditional shipping containers. Using fans for cooling would be energy-intensive. Another issue is that hot and cold air may condense into water within the relatively enclosed container, affecting the safety of the electrolyzer during operation and the aesthetics of the interior. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a large-capacity electrolyzer hydrogen production container, aiming to overcome at least one related technical problem existing in the background art. This will facilitate the promotion of hydrogen production equipment and the popularization of hydrogen energy, playing a crucial role in the development of the entire hydrogen energy industry.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This application provides an innovative large-capacity electrolyzer hydrogen production container. Its core concept lies in designing a container structure with an openable top, integrated hoisting system, efficient natural heat dissipation, and organized drainage, providing a factory-like operating environment for large-capacity electrolyzers.

[0006] Specifically, the hydrogen production container includes a container frame that serves as the main supporting structure. The frame is topped with a removable roof, a design key to this invention.

[0007] In order to provide an unprecedentedly spacious vertical working space during the assembly and maintenance of electrolytic cells, this application designs the ceiling to be removable as a whole by hoisting.

[0008] Meanwhile, to maintain the overall rigidity and stability of the frame when the roof is open and to provide additional reinforcement when closed, this application connects a detachable movable crossbeam to the upper part of the container frame. This design allows technicians to remove the roof and crossbeams sequentially when needed, creating a completely open top. This facilitates the direct and smooth lifting of large hoisting equipment into the container for assembly, greatly improving work efficiency.

[0009] In terms of hoisting and transportation, this utility model constructs a unique multi-point force-bearing hoisting system. To achieve stable and safe hoisting of the heavy container as a whole and prevent the frame from deforming due to stress concentration, this application sets movable and concealed hoisting points on the I-beam base. These hoisting points can be stored within the base outline when not in use, without affecting placement and transportation; they can be easily moved out when in use.

[0010] To work in conjunction with the concealed lifting points and optimize the force transmission path, this application incorporates load-bearing struts on the detachable roof. During lifting, the lifting rope connects to the concealed lifting points at the bottom and then passes upwards through the load-bearing struts on the roof. This ingenious design transforms the traditional single-point or localized force distribution into a force that is distributed throughout the entire roof and upper frame structure via the struts, before being transmitted to the base, forming a stable spatial force system. This ensures the container structure remains safe and reliable even when lifting loads of tens of tons.

[0011] Regarding heat dissipation, this invention abandons the high-energy-consumption forced cooling approach and instead utilizes physical principles. To efficiently dissipate the enormous heat generated during electrolytic cell operation in a zero-energy manner, this application incorporates natural exhaust vents on the removable roof. Its working principle utilizes the "chimney effect," where hot air, being less dense, naturally rises, allowing hot air to be continuously discharged from the exhaust vent located at the highest point, while cool air replenishes from the bottom, forming an efficient natural convection circulation.

[0012] To prevent external flying insects and debris from entering the chamber through the exhaust vent and interfering with the equipment operation, this application preferably installs an insect screen at the natural exhaust vent, ensuring both smooth airflow and a clean internal environment.

[0013] Regarding internal environmental management, to address the issue of draining potential condensate or accidental leaks within the enclosure, eliminate safety hazards caused by water accumulation, and maintain an aesthetically pleasing interior, this application includes a drip tray on the equipment mounting surface of the I-beam base. This drip tray is capable of collecting all dripping liquids.

[0014] To ensure that the collected liquid can be effectively and controllably discharged and to avoid long-term water accumulation in the tray, this application further provides a directional drainage structure (such as a preset slope or drain pipe joint) on the bottom surface of the water receiving tray, thereby guiding the liquid to the designated discharge point according to the designed route.

[0015] In addition, to facilitate daily inspections, debugging and maintenance by operators, the container frame is also equipped with a detachable sliding door, providing flexible access for personnel and small tools.

[0016] In summary, through the collaborative design and innovative integration of the above-mentioned subsystems (openable top structure, integrated hoisting system, natural heat dissipation system, and organized drainage system), this utility model successfully provides a containerized solution for large-capacity alkaline electrolyzers that is easy to assemble, safe to transport, economical to operate, and intelligent to manage, thus powerfully promoting the modularization and popularization of large-scale hydrogen production equipment.

[0017] The beneficial effects that a large-capacity electrolyzer hydrogen production container disclosed in this application may bring include, but are not limited to: Improved assembly and maintenance efficiency: The design of a detachable roof and movable crossbeams creates an open working space at the top, making the hoisting and installation of large-capacity electrolytic cells, pipeline connection and equipment maintenance convenient and efficient, significantly shortening the construction cycle and reducing labor costs.

[0018] Ensuring the safety and convenience of overall lifting and transfer: The innovative integrated lifting system, consisting of "concealed lifting points + load-bearing struts," achieves multi-point balanced force under heavy loads, effectively preventing the risk of structural deformation of the container frame during lifting and improving the safety and reliability of transfer operations. The concealed design also ensures that the lifting points do not affect the placement and movement of equipment when not in use.

[0019] Significantly reduced system operating energy consumption: The natural convection cooling system, constructed using natural exhaust vents and the principle of hot air rising, achieves zero-energy, high-efficiency emission of the large amount of heat generated during electrolyzer operation. Compared to traditional forced air cooling solutions, it eliminates the continuous power consumption of high-power fans, significantly improving the overall energy efficiency and economy of the hydrogen production system.

[0020] It effectively improves the safety and reliability of system operation: by setting up water collection trays and drain outlets, the problem of condensate and leaking liquid management inside the container is systematically solved, avoiding safety accidents such as electrical short circuits and equipment corrosion caused by water accumulation, extending the service life of the equipment, and ensuring the continuous and stable operation of the hydrogen production process.

[0021] The internal environment and aesthetics have been optimized: organized drainage and efficient heat dissipation work together to maintain a dry and clean operating environment inside the container, which not only facilitates equipment maintenance but also enhances the overall aesthetics and professional image.

[0022] The container features a modular and universal design: its structure is rationally designed with clear functional modules, and it has good versatility and scalability. It can be used as a standardized unit for the construction of large-scale hydrogen production plants, which strongly promotes the modular development and commercial application of large-scale water electrolysis hydrogen production equipment.

[0029] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] like Figure 1-5As shown, this application provides a large-capacity electrolyzer hydrogen production container. The core structure of this application includes a main container frame 1. Its innovation lies in the fact that the top of the container frame 1 is provided with a detachable roof 2, and the detachable roof 2 is provided with a load-bearing support rod 3 for distributing the force during hoisting and a natural exhaust port 4 for natural heat dissipation; the bottom of the container frame 1 is provided with an I-beam base 5, and the I-beam base 5 is provided with a hidden lifting point 6; the side or top of the container frame 1 is provided with a detachable movable crossbeam 7.

[0032] In this embodiment, the detachable canopy 2 and movable crossbeam 7 are provided so that the top of the container can be opened during the assembly and maintenance of the electrolytic cell, providing a huge vertical operating space. This makes it convenient for large hoisting equipment to directly lift the huge electrolytic cell body and its pipeline system into or out of the container, greatly improving the efficiency of assembly and maintenance, and solving the problem that large-volume electrolytic cells cannot be put in, installed, or repaired.

[0033] like Figure 3 As shown, in this embodiment, the support struts 3 and hidden lifting points 6 are provided to ensure the smooth and safe lifting and transfer of the container as a whole. During lifting, the ropes pass through the support struts 3 on the roof and connect to the hidden lifting points 6 at the bottom, forming a multi-point force system from top to bottom. This system evenly distributes the lifting force across the entire container frame 1, avoiding structural deformation caused by stress concentration, and is particularly suitable for the transportation of heavy equipment.

[0034] In this embodiment, the natural exhaust port 4 is provided to utilize the principle of hot air rising, so that heat can be naturally discharged without relying on a fan when the electrolytic cell is running, forming an effective "chimney effect", which significantly reduces the forced heat dissipation energy consumption of the container and solves the heat dissipation problem of large-volume tanks.

[0035] Assembly process: Lift open the removable roof 2 and remove the movable crossbeam 7 to create a top opening. Lift the electrolytic cell into the box for positioning and pipe connection.

[0036] Transfer process: The concealed lifting point 6 can be moved out using a crowbar. One end of the lifting rope is connected to the lifting point, and the other end passes through the ceiling support rod 3 and is connected to the crane. The crane lifts the frame, and the force is transferred to the entire frame through the support rod and the lifting point, achieving a stable overall transfer.

[0037] Operating process: The electrolytic cell generates heat, and the hot air rises and is discharged from the natural exhaust port 4. External cold air is replenished from the bottom or side, forming natural convection heat dissipation.

[0038] The movable crossbeam 7 can be a detachable structure connected by bolts, pins, or quick clamps. The natural vent 4 can be a louvered, grille-type, or simple opening.

[0039] To prevent flying insects, leaves, and other debris from entering the container through the natural vent 4, in some embodiments, an insect screen 10 is installed at the natural vent 4. This avoids interference or contamination of the electrolytic cell operation and ensures a clean internal environment.

[0040] The insect net 10 acts as a physical barrier, allowing free airflow while effectively blocking small foreign objects. The insect net 10 can be made of materials such as metal wire mesh or nylon mesh. It can be installed by embedding it into the door frame or by fixing it with a molding strip.

[0041] To allow the lifting points to be retracted within the base profile when not in use, without affecting the placement and transportation of containers, the concealed lifting points 6 are movably mounted on the I-beam base 5. They can be easily removed during use, providing a lifting interface. This "movable" design improves the overall integrity and convenience of the equipment.

[0042] The concealed suspension point 6 can be a flip-type, pull-out type, or plug-in type suspension point structure. The suspension point can be moved or flipped through a sliding groove, hinge, or plug-in connection. In this embodiment, the concealed suspension point 6 adopts a pull-out type, that is, the ceiling is normally slidably connected to the container frame 1; it is pulled out by a pry bar when in use.

[0043] In order to collect and drain any condensate or accidental leaks that may occur inside the container, and to address potential electrical safety hazards and equipment corrosion caused by moisture accumulation, the I-beam base 5 is equipped with a water collection tray 8 for guiding and draining internal water.

[0044] The water collection tray 8 is located at the bottom of the equipment and has a certain slope, which can guide the collected liquid to the preset drain outlet and discharge it outside the tank according to the designed route. At the same time, it keeps the interior of the skid look neat.

[0045] The water receiving tray 8 can be a single, integral tray structure, or it can be a system composed of multiple guide channels. Its material can be stainless steel, galvanized sheet, or corrosion-resistant plastic.

[0046] To facilitate daily inspection, debugging and maintenance of other auxiliary equipment inside the container by operators, and to provide flexible access, the container frame 1 is equipped with a detachable movable door 9.

[0047] The detachable sliding door 9 is connected to the frame via hinges and bolts or quick-locking devices, and can be opened or completely removed when needed. The detachable sliding door 9 can be a single door, a double door, or a roller shutter door.

[0048] In some embodiments, the movable beam 7 is explicitly connected to the upper part of the container frame 1. Positioning the movable beam 7 on the upper part of the frame provides maximum top opening space after removal, optimizing the lifting operation range. Simultaneously, in the installed state, it effectively enhances the structural rigidity and overall stability of the container top.

[0049] The movable crossbeam 7 acts as a reinforcing member, working together with the longitudinal beams at the top of the frame to bear the stresses brought about by hoisting, transportation, and wind loads. The cross-sectional shape of the movable crossbeam 7 can be I-beam, channel steel, or rectangular tube.

[0050] The "movable" in "movable beam 7" means that the beam can be removed after installation, not that the beam can slide after installation.

[0051] To clarify and optimize the lifting mechanics path, the lifting rope is passed through the support rod 3, which changes the direction and point of application of the lifting force, enabling multi-point lifting of the container frame 1. This distributes the force, originally concentrated at one point, across the roof and the entire frame, forming a stable multi-point lifting system, effectively preventing frame deformation and ensuring absolute safety during heavy-load lifting.

[0052] During hoisting, the rope forms a loop, with the lower part connected to the base lifting point and the upper part passing through (or around) the load-bearing strut 3 in the ceiling before connecting to the hook. The strut acts as a fixed pulley-type guide and load-bearing point.

[0053] Optionally, the support rod 3 can be a steel pipe directly welded to the ceiling, or a special pulley block installed through a support.

[0054] To ensure that the collected liquid can be discharged from the tank efficiently and in a controlled manner, and to prevent water accumulation in the tray, a drain outlet is provided on the bottom surface of the water receiving tray 8. The drain outlet design prevents water from dripping indiscriminately, meeting environmental protection and on-site management requirements.

[0055] By making the bottom surface of the water receiving tray 8 into a sloped surface with a certain gradient, or by integrating and installing a drain pipe joint, water can be directed to a designated collection point or drainage system.

[0056] In some embodiments, the detachable canopy 2 is detached from and reassembled with the container frame 1 by means of hoisting. The canopy itself is prefabricated with lifting lugs or lifting points, and can be lifted off the frame as a whole or placed back into the frame using a crane.

[0057] Regarding the detachable canopy 2, it can be either a single piece or a modular assembly to suit different lifting capacity requirements.

[0058] In some embodiments, the natural exhaust vent 4 is specifically located at the top or upper side of the removable ceiling 2. Positioning the exhaust vent at the highest point is to most effectively utilize the principle of hot air rising, ensuring that hot air is directly exhausted after accumulating to its highest point, forming the strongest thermal pressure driving force and achieving the best natural ventilation and heat dissipation effect.

[0059] The working principle of this large-capacity electrolyzer hydrogen production container is a systematic and integrated design process centered around the entire lifecycle of "assembly-transfer-operation," with its core lying in the coordinated operation of various functional modules. The working principle is explained in detail below: 1. Working principle for convenient assembly and maintenance: During the initial installation of the electrolytic cell or subsequent major maintenance, the removable roof 2 is first removed entirely using hoisting equipment. Then, the movable crossbeam 7 connected to the upper part of the container frame 1 is removed. This operation transforms the traditional enclosed container into an open working cabin with a completely open top, providing unobstructed vertical operating space for large hoisting equipment.

[0060] The electrolytic cell and its associated piping system can be directly and vertically hoisted into the enclosure and precisely positioned and secured on the I-beam base 5. This design fundamentally changes the traditional method of difficult assembly in confined spaces, elevating the efficiency of accommodating large equipment to a new level.

[0061] 2. Working principle of safe and stable transfer: When the container needs to be moved as a whole, its integrated lifting system is activated. First, the concealed lifting points 6 located on the I-beam base 5 are moved out or flipped to the working position. Then, one end of the lifting rope is connected to these lifting points, and the other end passes upward through the load-bearing strut 3 on the removable canopy 2, and finally connects to the hook of the lifting equipment.

[0062] During the lifting process, the lifting force is first transferred to the concealed lifting point 6 at the bottom, and then guided to the load-bearing strut 3 at the top via the lifting ropes. At this time, the load-bearing strut 3 acts as a key force distributor, laterally distributing the localized stress originally concentrated on the ropes to the entire roof structure, and further transferring it to the entire container frame 1. This multi-point load-bearing system of "bottom bearing and top force distribution" effectively avoids the torsion or plastic deformation of the frame due to stress concentration when lifting heavy objects, ensuring absolute safety and structural integrity during the transfer process.

[0063] 3. Working principle of high-efficiency and energy-saving heat dissipation: During the operation of the electrolytic cell, a large amount of heat energy is generated. This invention fully utilizes thermodynamic principles to construct a highly efficient passive heat dissipation system. The heat generated by the electrolytic cell heats the surrounding air, causing the hot air density to decrease and rise naturally. The hot air accumulates inside the chamber and is eventually continuously discharged from the natural exhaust port 4 located at the highest point of the ceiling.

[0064] Meanwhile, cooler outside air is supplied through gaps in the bottom of the container or specially designed air inlets, creating a stable, thermo-pressure-driven natural convection circulation inside the container. This process is entirely powered by natural forces, eliminating the need for large electrical fans and significantly reducing operating energy consumption. The insect screen 10 installed at the exhaust vent effectively prevents the entry of foreign objects without affecting airflow.

[0065] 4. Working principle of intelligent and orderly drainage: To address potential condensation or accidental leaks caused by temperature differences within the enclosure, this invention employs an organized drainage system. All dripping liquid is collected by a drip tray 8 positioned beneath the equipment. The bottom of this tray 8 is designed with a drainage outlet structure, featuring a specific directional drainage mechanism (such as a preset slope or integrated drain pipe) that automatically guides the collected liquid to the designated outlet and discharges it out of the enclosure in an orderly manner along the designed path. This mechanism effectively prevents disorderly water accumulation within the enclosure, eliminating safety hazards such as short circuits and corrosion caused by water accumulation, while simultaneously maintaining a dry and clean internal environment.

[0066] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
