Description

Technical Field

[0001] The utility model relates to the technical field of gas storage, and in particular to a split-type, unloadable, easily replaceable and flexible hydrogen storage container. Background Art

[0002] The problems faced by fossil energy are constrained by both the total amount of resources and environmental issues such as global warming. Hydrogen energy has the advantages of zero pollution, abundant resources, and high calorific value. It has become a recognized ideal new energy source and is even considered the ultimate solution to human energy problems. Hydrogen storage is a key issue that must be solved in the use of hydrogen energy. Hydrogen is flammable and explosive, easy to leak, easy to cause hydrogen embrittlement of materials, light weight and difficult to compress, which brings great challenges to its safe and efficient storage. Although there are currently many hydrogen storage modes such as liquid hydrogen, material combination or adsorption, high-pressure hydrogen storage is still the dominant mode.

[0003] At present, most of the hydrogen storage bottles on the market are high-pressure hydrogen storage bottles (filled with compressed hydrogen) and alloy hydrogen storage bottles (filled with solid hydrogen storage alloys). The design features of hydrogen storage bottles correspond to the characteristics and requirements of the filling medium. High-pressure hydrogen storage bottles can be divided into Type I pure steel metal bottles, Type II steel liner fiber-wound bottles, Type III aluminum liner fiber-wound bottles, and Type IV plastic liner fiber-wound bottles. In order to make the bottle body withstand high pressure (350 or 700 atmospheres), the wall of the high-pressure hydrogen storage bottle is mostly thick and multi-layered, resulting in a large self-weight of the hydrogen storage bottle. In addition, even under high pressure compression, the density of gaseous hydrogen is still very small (700 atmospheres, 38g / L), making the volume required to accommodate enough hydrogen storage bottles larger. Therefore, most high-pressure hydrogen storage bottles that store hydrogen with high-pressure gaseous hydrogen are relatively bulky and difficult to adapt to the requirements of portable applications with high volume and weight requirements. In addition, the high-pressure state of the gas poses a safety hazard, and in order to reduce the self-weight of the bottle body, a large proportion of new high-pressure hydrogen storage bottles use carbon fiber composite materials, resulting in a high production cost of hydrogen storage bottles. The alloy hydrogen storage bottle contains a hydrogen storage alloy that can absorb and release hydrogen cyclically. The alloy material is sealed into the bottle body during the manufacturing process of the hydrogen storage bottle, and the subsequent hydrogen absorption and release processes all take place in the hydrogen storage bottle. Since the hydrogenation process of the hydrogen storage alloy still needs to be carried out under hydrogen pressure, the alloy hydrogen storage bottle is still required to withstand a certain pressure, and the bottle wall still needs to be designed to be pressure-resistant, which increases the dead weight to a certain extent. At the same time, the hydrogen storage alloy releases heat during the hydrogenation process, so it is often necessary to equip it with active or passive cooling components / measures, which further increases the dead weight of the bottle. In addition, the hydrogen storage density of most hydrogen storage alloys is relatively limited, and the heavy weight of the hydrogen storage bottle leads to a low overall hydrogen density (<1 wt.%). Utility Model Content

[0004] To this end, the utility model provides a split type removable and easily replaceable portable hydrogen storage container to solve the above-mentioned problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A split type removable and easily replaceable portable hydrogen storage container, comprising a hydrogen buffer zone, a hydrogen supply side integrated interface, a supporting filter plate, a hydrogen storage material cabin and a tank body, wherein the hydrogen supply side integrated interface is provided with a gas path interface and a hydrogen outlet pipe;

[0007] Among them, the top of the tank body is sealed and connected to the integrated interface on the hydrogen supply side; a supporting filter plate is arranged at the inner arc corner of the tank body to divide the internal space of the tank body into an upper hydrogen buffer zone and a lower hydrogen storage material cabin; the gas path interface is arranged at the center position of the integrated interface on the hydrogen supply side, and is connected to the hydrogen outlet pipe at the bottom.

[0008] The hydrogen outlet pipe is integrated with the hydrogen supply side integrated interface. A gas outlet groove is opened at the bottom center of the hydrogen supply side integrated interface, which is internally connected to one end of the gas circuit interface, and the other end of the gas circuit interface is connected to the hydrogen use side integrated interface.

[0009] Furthermore, the hydrogen storage material cabin adopts a three-layer structure, which includes a tank outer shell, an electric heating layer and a heat-conducting inner shell from the outside to the inside.

[0010] Furthermore, a temperature sensor hole is provided on the support filter plate corresponding to the position of the temperature sensor, so that the temperature sensor is inserted into the lower hydrogen storage material cabin to measure the temperature of the hydrogen storage material during operation.

[0011] Furthermore, the rest of the supporting filter plate is provided with a filter screen area to prevent material powder from entering the hydrogen buffer zone and subsequent pipelines during the dehydrogenation process.

[0012] Furthermore, the hydrogen supply side integrated interface is also provided with a temperature sensor connection point, a power supply interface and a pressure sensor connection point for connecting the temperature sensor, the power supply line and the pressure sensor respectively.

[0013] On the side of the hydrogen storage container (hydrogen supply), the corresponding sensors and power lines are connected below the connection point and the power interface respectively. When the integrated interface on the hydrogen supply side and the matching integrated interface on the hydrogen use side are installed, the connection point is connected with the corresponding connection point on the other side to realize the transmission of the sensor signal to the control system. The power interface is also connected with the interface on the other side and connected to the power supply. The power line is used to supply power and heat the electric heating layer to realize hydrogen release of the material.

[0014] Furthermore, the neck of the tank body is provided with a power cord outlet hole, a temperature sensor hole, a pressure sensor hole and a hydrogen outlet, through which the power cord, the temperature sensor, the pressure sensor and the hydrogen gas from the hydrogen outlet pipe are respectively passed and released.

[0015] Furthermore, a power cord is connected below the power interface. After passing through the power cord outlet below the integrated interface on the hydrogen supply side, the power cord is laid along the inner wall of the tank shell of the hydrogen buffer zone and connected to the electric heating layer.

[0016] Furthermore, the hydrogen storage container further comprises a tail cover, which is used to seal the tank body. A pressure relief valve or a bursting disc is arranged on the tail cover for overpressure protection.

[0017] Furthermore, the hydrogen storage container also includes a discharge port for filling or unloading the hydrogen storage material inside the hydrogen storage container.

[0018] Furthermore, the circuits of the hydrogen-using-side integrated interface matching the hydrogen-supply-side integrated interface of the hydrogen storage container include: a gas circuit, a pressure signal transmission line, a temperature signal transmission line, and a power line.

[0019] Each connection point and interface of the integrated interface on the hydrogen-using side is connected to the corresponding signal transmission line, gas line and power line respectively. The integrated line can be deployed as needed in the subsequent system of the integrated interface on the hydrogen-using side, and then divided into bundles and connected to the corresponding units.

[0020] The utility model has the following advantages:

[0021] The design of the utility model integrates the gas circuit, sensor and power supply interface. When installing / disassembling the hydrogen storage container, the user only needs to operate the integrated interface on the hydrogen supply side and the integrated interface on the hydrogen use side (such as simple plugging and unplugging) to achieve simultaneous connection / disconnection of the gas circuit, signal and power supply, thereby allowing the user to easily and quickly replace the hydrogen storage container unit.

[0022] The utility model is easy to unload and load: the split design is convenient for unloading and loading the hydrogen storage material. When the performance of the hydrogen storage material decreases or needs to be replaced with other types of hydrogen storage materials, the operator can easily take out the old material from the hydrogen storage material compartment and replace it with new material, which is conducive to the long-term use and maintenance of the hydrogen storage container.

[0023] The detachable split design of the utility model allows the hydrogenation process after the material releases hydrogen to not be carried out in the container. When the hydrogenation mode is adopted outside the container, the hydrogen storage container does not need to withstand high pressure, thereby making the hydrogen storage container more flexible and better maintaining the advantage of the high density of the hydrogen storage material. At the same time, it brings greater flexibility to the geometric design of the container and the selection of the tank material, thereby reducing costs.

[0024] The utility model divides the interior of the tank into a hydrogen buffer zone and a hydrogen storage material compartment by supporting the filter plate. This partitioning provides a dedicated buffer zone for hydrogen during storage, which is conducive to stabilizing the state of hydrogen. During the hydrogen charging and discharging process, the hydrogen buffer zone can reduce the impact of pressure fluctuations on hydrogen storage materials or subsequent components of the system, thereby improving the safety and stability of the entire system.

[0025] The utility model has the auxiliary function of supporting the filter plate: in addition to dividing the space, the supporting filter plate can also support the hydrogen storage material to a certain extent, and at the same time filter out possible impurities such as hydrogen storage material particles to prevent them from entering the hydrogen outlet pipe and other gas path systems, thereby reducing the risk of gas path blockage and equipment damage, and indirectly reducing maintenance costs.

[0048] In one embodiment, two temperature sensor connection points 7 and one pressure sensor connection point 29 are provided, and the temperature sensor connection points 7 are symmetrically distributed on both sides of the gas circuit interface; if a pressure sensor is provided in the subsequent gas circuit, the pressure sensor connection point 29 (pressure sensor 8) is not necessary.

[0053] Preferably, the hydrogen storage container further comprises a discharge port 24 for loading or unloading the hydrogen storage material inside the hydrogen storage container.

[0056] Each connection point and interface of the hydrogen-using side integrated interface 31 matching the hydrogen-supply side integrated interface 2 are respectively connected to the corresponding signal transmission lines, gas circuits and power lines. The integrated lines can be deployed as needed in the subsequent system of the hydrogen-using side integrated interface 31, and then branched and connected to each corresponding unit. The gas circuit and lines of the hydrogen-using side integrated interface 31 include: gas circuit 26, pressure signal transmission line 27, temperature signal transmission line 28 and power line 30.

[0057] In the present invention, the container shape: since the container system is under low pressure or normal pressure conditions, its geometric shape can be flexibly customized and selected according to the spatial characteristics of the application scenario;

[0058] Container volume: The container is divided into multiple volume versions according to the different hydrogen requirements of the application scenario;

[0059] Heat conduction measures inside the container: The material distribution inside the container and the corresponding heat conduction measures are adjusted according to the geometric shape and volume of the container; when the container volume is very small, no additional heat conduction measures are required, but when the container is large and the internal filling material is large, corresponding internal heat conduction measures are required; the specific internal heat conduction measures can be to insert a heat conduction plate or a heat conduction net, press the material into shape and then fill it in the grid; or wrap the pressed material with a heat conductor, make it into a hydrogen storage material module and then fill the tank;

[0064] The detachable split design of the utility model allows the hydrogenation process after the material releases hydrogen to not be carried out in the container. When the mode of hydrogenation outside the container is adopted, the hydrogen storage container does not need to withstand high pressure, which can make the hydrogen storage container more flexible and better maintain the advantage of high density of hydrogen storage materials. Therefore, the mode of hydrogenation outside the container allowed by the utility model makes it also applicable to hydrogen storage compounds with significantly higher hydrogen storage capacity (>8 wt.%) but cannot be directly hydrogenated under hydrogen pressure, thereby obtaining a hydrogen storage unit with significantly higher energy density than the prior art. When making this application, firstly, since the material cycle hydrogenation process is no longer carried out in the container, and the material can stably store hydrogen at room temperature and pressure, the hydrogen storage container does not need to withstand high pressure; this brings greater flexibility to the geometric design of the container and the selection of tank materials, so that the hydrogen storage container can adapt to more application environments and scenarios, and can effectively reduce the cost and deadweight of the tank, effectively retain the high hydrogen density advantage of the material itself, and at the same time improve the economy and flexibility of the hydrogen storage tank. Secondly, the hydrogenation of the material is not carried out in the container, and the tank does not need to carry out the heat dissipation design related to the hydrogenation process, thereby further reducing the weight and volume of the tank. At the same time, the utility model adds a filling / discharging port at the rear of the tank body to facilitate the unloading and filling of the tank body after recovery, and the filling / discharging port is sealed by the tail cover. In addition, the gas circuit, sensor signal transmission, and electric heating wire power supply heating are integrated into the bottle mouth interface to achieve the feature of easy replacement of the hydrogen storage container, so that users can easily and quickly replace the container.

[0065] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
