Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen energy storage equipment, and in particular to an integrated hydrogen storage cabin. Background Art

[0002] As a clean and efficient secondary energy source, hydrogen energy's industrial chain covers hydrogen production, storage, transportation, and use. Among them, hydrogen storage is the core hub connecting hydrogen production and use, which directly affects the large-scale application efficiency and safety of hydrogen energy.

[0003] With the rapid development of renewable energy hydrogen production technology and the gradual popularization of downstream applications such as hydrogen refueling stations and hydrogen fuel cell vehicles, the market has put forward higher requirements for the modularity, easy transportation, scalability and high safety characteristics of hydrogen storage equipment.

[0004] However, existing hydrogen storage equipment mostly adopts an integrated welded structure, which still has the following prominent problems: 1. Poor expansion flexibility: The integrated structure has a fixed hydrogen storage capacity, and the number of hydrogen storage modules cannot be flexibly increased according to user needs. If capacity expansion is required, the entire cabin must be replaced, resulting in a waste of resources.

[0005] 2. Low installation and maintenance convenience: The internal space of the integrated cabin is closed, making it difficult for maintenance personnel to enter. The installation, replacement or troubleshooting of the hydrogen storage module sometimes requires disassembly of the cabin, which is time-consuming and labor-intensive, affecting the operating efficiency of the equipment.

[0006] 3. Insufficient safety protection: The sealing structure design of some hydrogen storage equipment is simple, which can easily lead to hydrogen leakage due to weld corrosion or vibration; the insulation measures are not perfect, and the optimal operating temperature of the hydrogen storage module cannot be maintained, affecting the hydrogen storage efficiency.

[0007] To address the above issues, the industry urgently needs a modular, easy-to-transport, easy-to-expand, easy-to-install and maintain, safe and reliable hydrogen storage equipment to meet the needs of the rapid development of the hydrogen energy industry. Summary of the Invention

[0008] In order to solve the problems existing in the above-mentioned background technology, such as the difficulty in expanding the hydrogen storage capacity of the overall structure of traditional hydrogen storage equipment, insufficient cabin sealing performance, narrow installation and maintenance space, and imperfect safety protection, the present invention provides an integrated hydrogen storage cabin, which realizes modular transportation and capacity expansion through a split splicing structure, improves the safety of hydrogen storage through a double-layer sealing and insulation design, improves the convenience of installation and maintenance through a dedicated inspection channel and door structure, and reduces the risk of explosion through multiple safety protection measures, ultimately realizing the safe, convenient and scalable hydrogen storage needs.

[0009] To achieve the above object, the present invention adopts the following technical solutions: An integrated hydrogen storage cabin adopts a split splicing structure, including a front part and a rear part, each of which is composed of an odd number of splits, and the front part and the rear part are symmetrically arranged front to back, and all the splits of the front part and the rear part are connected to form a closed hydrogen storage cabin body; the middle split of the front part and the rear part is a maintenance corridor for personnel operation and equipment maintenance in the cabin, the lower part of the left and right splits of the front part and the rear part is a hydrogen storage module installation area for fixing and accommodating the hydrogen storage unit, and the upper part of the left and right splits is a pipeline routing area for installing hydrogen transmission pipelines and various electrical equipment.

[0010] Specifically, the bottom of all the splits in the front and rear parts are provided with a base frame as the load-bearing foundation of the cabin, bearing the weight of the hydrogen storage module and the cabin itself; a row of several vertical support tubes are provided on the two outer sides of the left and right splits, which are connected to the base frame, and a horizontal tube is provided on the top of each row of the vertical support tubes in the horizontal direction to connect the several vertical support tubes for the subsequent installation of the top plate. The row of vertical support tubes close to the middle side is higher than the row of vertical support tubes on the outer side, so as to ensure that the top plate has an inclination angle, and at the same time, an extended support arm is connected to the outside; two rows of vertical narrow support tubes are also provided on both sides of the middle split corresponding to the vertical support tubes of the adjacent splits, and the top of the vertical narrow support tubes is connected to the horizontal narrow tube in the horizontal direction, and is respectively connected to the adjacent splits after splicing. When all the splits are assembled, all the support tubes are connected together, and combined with the horizontal tubes and the extended support arms to form a support frame of the hydrogen storage cabin, which bears the weight, enhances the stability of the cabin, and prevents deformation of the cabin.

[0011] Specifically, anti-slip steel plates are laid above and below the base frame to prevent operation and maintenance personnel from slipping when walking in the cabin, adapting to the needs of industrial scenarios, and the bottom of the base is sealed to prevent foreign objects from entering; the gap between the two layers of anti-slip steel plates and the base frame is filled with glass wool to play a role in heat preservation and sound insulation, avoiding drastic changes in cabin temperature that affect the performance of the hydrogen storage module.

[0012] Specifically, all the split bodies are provided with walls on their outer sides, and the walls are connected to the adjacent vertical support tubes. The walls are provided with a double-layer steel plate structure, taking into account both impact resistance and load-bearing capacity. The outer layer is made of corrugated steel plates, which have good impact resistance and are suitable for harsh outdoor environments. The inner layer is ordinary steel plates, which serve as the wall load-bearing layer to ensure structural stability. The corrugated steel plates and the ordinary steel plates are connected by spot welding and sealed with glue to completely block the hydrogen leakage path. Glass wool is filled inside to enhance the thermal insulation and fireproof performance of the wall. The outer wall surface of the wall is sprayed with anti-corrosion paint to prevent the steel plate from rusting and extend the service life of the cabin. The left and right sides of the split bodies are left and right. The walls on both outer sides are provided with several equipment doors for the installation, replacement and maintenance of the hydrogen storage module. The equipment doors adopt the conventional container door structure with container lock rods, which are easy to open and close and meet the needs of convenient installation; U-shaped container straps are provided on the edges of the equipment doors to enhance the sealing performance of the door body and prevent hydrogen leakage; ventilation devices and automatic pressure relief valves are provided above the equipment doors. The ventilation devices are used to discharge hydrogen that may leak and accumulate in the cabin to avoid explosion caused by excessive hydrogen concentration. The automatic pressure relief valve is used to automatically release pressure when the cabin pressure exceeds a threshold to prevent the cabin body from being damaged due to overpressure; the equipment door is provided with a windproof pull rod to prevent damage to the door body in windy weather.

[0013] Specifically, inspection doors are provided at the front and rear of the middle split for personnel entry and exit and daily maintenance. Door stop strips and keel strips are provided at the edges of the inspection door. The door stop strips are used to support the door body, prevent collisions and increase the overall structural strength of the door frame. The keel strips enhance the sealing performance between the door body and the wall. The inspection door is a double-layer steel plate structure, with an outer layer of corrugated steel plate and an inner layer of ordinary steel plate. The interior is filled with glass wool, which is consistent with the thermal insulation performance of the wall. The door lock of the inspection door is a flat-push escape lock, which can be quickly pushed open to escape in an emergency, thereby improving personnel safety. An emergency light is provided above the inspection door to provide cabin lighting when the power is off, facilitating personnel evacuation or maintenance. The inspection door is also provided with a windproof pull rod to prevent damage to the door body in windy weather.

[0014] Specifically, the tops of all the splits are designed as a double-layer structure, which are the inner top plate and the outer top plate from the inside to the outside. Both the inner top plate and the outer top plate are made of steel plates to ensure the load-bearing and strength of the top; the outer top plates and the inner top plates of the left and right splits are respectively connected to the upper and lower edges of the horizontal tubes on their left and right sides and are connected to the extended support arms, forming an angle inclined outward for the smooth drainage of rainwater from the top, and at the same time, the gaps are spot welded and sealed with sealant to prevent rainwater from seeping into the cabin; the outer top plate and the inner top plate of the middle split are respectively connected to the upper and lower edges of the horizontal narrow tubes on both sides of themselves; glass wool is filled between the inner top plate and the outer top plate to enhance the thermal insulation performance of the top, and a top cover is buckled on the top of the middle split. The top cover has an inclined angle to both sides to cover the gaps that may exist after the splits are spliced, further preventing rainwater and dust from entering while draining rainwater smoothly; a lightning strip is set on the top of the top cover to lead lightning into the ground to prevent lightning damage to equipment in the cabin or cause a hydrogen explosion.

[0015] Specifically, a number of hydrogen storage module bases are provided in the hydrogen storage module installation areas of the left and right split bodies, and a number of hydrogen storage modules are correspondingly installed on the hydrogen storage module bases for storing hydrogen. The hydrogen storage modules are connected through transmission pipelines for the input and output of hydrogen. The transmission pipelines are arranged in the pipeline routing area, and the transmission pipelines penetrate the walls in front of the left and right split bodies and are connected to external hydrogen production and hydrogenation equipment.

[0016] Specifically, the pipeline wiring area is equipped with explosion-proof electrical appliances, such as explosion-proof switches and explosion-proof sockets, to prevent electric sparks from causing hydrogen explosions; metal open wire troughs are provided to standardize electrical wiring to avoid safety hazards caused by chaotic or aging lines; lighting is provided to provide operational lighting in the cabin; the explosion-proof electrical appliances and lighting lamps are all designed to be explosion-proof and meet the safety requirements of the hydrogen environment. All wiring is placed in the metal open wire troughs to facilitate maintenance and troubleshooting of line problems.

[0017] In summary, the beneficial technical effects of the present invention are: 1. Modular transportation and expansion: The split-type splicing structure allows the split parts to be disassembled and transported to on-site assembly, solving the problem of inconvenient transportation of traditional integral hydrogen storage equipment. If the hydrogen storage capacity needs to be expanded, the number of split parts can be increased to achieve on-demand expansion and adapt to the hydrogen storage needs of different scenarios.

[0018] 2. Convenience of installation and maintenance: Several equipment doors are installed on the left and right exterior walls corresponding to the positions of the hydrogen storage modules to facilitate the installation of the hydrogen storage modules. The middle part is a maintenance aisle, which provides ample operating space. Operation and maintenance personnel can enter the cabin through the maintenance door to facilitate maintenance of hydrogen storage modules, transmission pipelines and other equipment; the maintenance door adopts a flat-push escape lock, which allows quick escape in an emergency, thereby improving personnel safety.

[0019] 3. Sealing and thermal insulation performance: The walls are sealed with double-layer steel plates that are spot-welded and glued, filled with glass wool inside, and sprayed with anti-corrosion paint on the walls, which effectively prevents hydrogen leakage and solves the problem of insufficient sealing of traditional hydrogen storage cabins. At the same time, the glass wool filling layer maintains a stable temperature inside the cabin, preventing drastic temperature changes from affecting the hydrogen absorption and desorption efficiency of the hydrogen storage module and other performance.

[0020] 4. Multiple safety protections: Explosion-proof electrical appliances are used in the cabin to prevent explosions caused by electric sparks; a ventilation device is installed above the equipment door on the equipment installation surface to discharge hydrogen accumulated in the cabin to prevent hydrogen concentration from exceeding the standard; the automatic pressure relief valve releases pressure when the cabin is over-pressurized to prevent damage to the cabin; the lightning protection strip on the top of the top cover prevents lightning strikes. Multiple safety measures jointly ensure the safe operation of the hydrogen storage cabin.

[0021] 5. Structural stability: The support frame consists of multiple vertical support tubes, horizontal tubes, and extended support arms, and is connected to the base, wall, and top as a whole, which enhances the structural strength of the cabin and adapts to harsh outdoor environments.
