Technical Field

In scenarios with diversified energy demands, fixed hydrogen storage equipment cannot meet diverse needs, which also limits the scope of application of hydrogen energy.

[0005] Finally, existing hydrogen storage devices heat the hydrogen storage material through direct contact. This heating method is not only slow, but also increases energy loss, greatly reducing the efficiency of hydrogen storage. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0040] See also Figure 1-3 As shown, the embodiment of the utility model provides a solid-state hydrogen storage device, which includes a container 1, a solid-state hydrogen storage tank group 2 and a connection structure 3. The solid-state hydrogen storage tank group 2 is installed inside the container 1, and the solid-state hydrogen storage tank group 2 includes a plurality of evenly distributed hydrogen storage tanks 21, wherein:

[0041] Each hydrogen storage tank 21 includes hydrogen absorbing metal particles 211, a tank body 212, a thermal insulation material 214, an electromagnetic induction heating cable 215 and a shielding layer 216. The hydrogen absorbing metal particles 211 are filled in the tank body 212, the thermal insulation material 214 is coated on the outer surface of the tank body 212, the electromagnetic induction heating cable 215 is wound on the thermal insulation material 214, and the shielding layer 216 covers the outer surface of the electromagnetic induction heating cable 215.

[0042] The connection structure 3 is fixedly connected to the end of each hydrogen storage tank 21 to charge or discharge hydrogen into or out of the hydrogen storage tank 21 and detect the hydrogen pressure and temperature in real time.

[0043] When the electromagnetic induction heating cable 215 is powered to generate an induced magnetic field, the induced magnetic field interacts with the hydrogen absorbing metal particles 211 , thereby heating the hydrogen absorbing metal particles 211 and reacting with hydrogen to generate solid hydrogen storage.

[0044] Specifically, see Figure 1 , 2 As shown in Figure 3, in this embodiment, the solid-state hydrogen storage device is composed of a container 1, a solid-state hydrogen storage tank group 2 and a connecting structure 3, wherein the cross-sectional schematic diagram of the container 1 presents a precise and efficient energy storage structure. As a preferred embodiment of this embodiment, the container 1 is composed of nine hydrogen storage tanks 21 tightly integrated and installed together, and the hydrogen storage tanks 21 are interconnected through gas pipelines to ensure smooth circulation and storage of hydrogen. This compact design not only improves space utilization, but also enhances the stability of the overall structure.

[0045] like Figure 2 As shown, in the container 1, each hydrogen storage tank 21 is composed of hydrogen absorbing metal particles 211, a tank body 212, a thermal insulation material 214, an electromagnetic induction heating cable 215 and a shielding layer 216, wherein the thermal insulation material 214 is cleverly arranged between the electromagnetic induction heating coil 215 and the tank body 212, which not only ensures the heating efficiency but also avoids unnecessary heat loss.

[0046] The electromagnetic induction heating cable 215 is the heating source of the solid-state hydrogen storage device. Through the principle of electromagnetic induction, the heat energy generated by the electromagnetic induction heating cable 215 can be quickly and evenly transferred to the hydrogen storage tank 21, thereby realizing rapid heating of the hydrogen-absorbing metal particles 211. This heating method controlled by the PLC system is not only highly efficient, but also can achieve precise control of the temperature.

[0047] For example, when the electromagnetic induction heating cable 215 is powered on, the induced electromagnetic field generated by it cuts the alternating magnetic lines of force of the tank body 212, thereby exciting an alternating current inside the metal. This process realizes the conversion of electrical energy into magnetic energy, so that the heated metal tank body senses the magnetic energy and generates heat. This non-contact heating method is not only highly efficient and energy-saving, but also avoids the potential safety hazards caused by traditional heating methods.

[0048] It should be particularly noted that in order to maintain a stable temperature inside the tank body 212, this embodiment uses an efficient thermal insulation material 214 to cover the tank body 212. This thermal insulation material 214 has good thermal insulation performance, can effectively reduce heat loss, and improve the energy efficiency of the system. In this embodiment, the thermal insulation material 214 is preferably thermal insulation cotton, which is convenient for obtaining materials and can also ensure the thermal insulation effect.

[0049] In addition, the hydrogen absorbing metal particles 211 are the core part of the solid-state hydrogen storage device. The hydrogen absorbing metal particles 211 are loaded into a carefully designed tank body 212. These metal particles have excellent hydrogen absorption capacity and can store hydrogen safely and efficiently at normal temperature and pressure.

[0050] Furthermore, the container 1 includes a tank body connector 11 and a frame fixture 12 , and the tank body connector 11 is used to connect between adjacent hydrogen storage tanks 21 and between the frame fixture 12 and the hydrogen storage tank 21 , so that the hydrogen storage tank 21 is fixedly connected in the frame fixture 12 .

[0051] The container 1 is made of high-strength material and has excellent compression and impact resistance, ensuring safety and stability during transportation. It is worth mentioning that the container 1 is also lightweight and easy to move and transport.

[0052] Through reasonable structural design, the weight of the container 1 is effectively controlled, so that it can be easily carried in various environments. In addition, the container 1 is also equipped with a convenient loading and unloading device, making it more convenient and quick during transportation.

[0053] Furthermore, the hydrogen storage tank 21 also includes a non-metallic support member 213 rigidly supported between the tank body 212 and the electromagnetic induction heating cable 215 .

[0054] Therefore, the non-metallic support parts 213 play a vital role in the system. They are used to connect the electromagnetic induction heating cable 215 and the tank body 212 to provide stable rigid support. This design not only ensures the structural stability of the system, but also avoids the potential safety hazards caused by metal parts.

[0055] Furthermore, the connection structure 3 includes fixed support members 31 fixedly supported at both ends of the tank body 212 and a thermal insulation board 36 installed between the fixed support members 31 and the thermal insulation material 214 .

[0056] Specifically, the fixed support member 31 is used to fix the two ends of the support tank body 212, and the thermal insulation board 36 is installed between the fixed support member 31 and the thermal insulation material 214 to isolate the heat source from contacting the fixed support member 31 and avoid heat loss.

[0057] Furthermore, the connection structure 3 also includes an air inlet 32 ​​and an air outlet 34 communicated with the interior of the tank body 212 , and the air inlet 32 ​​and the air outlet 34 are fixed on the fixed support member 31 .

[0058] Thus, the tank body 212 is filled with hydrogen through the air inlet 32 ​​and is adsorbed by the hydrogen absorbing metal to form a stable form; the hydrogen in the tank body 212 is discharged through the exhaust port 34.

[0059] Furthermore, the connection structure 3 further includes a temperature sensor 33 and a pressure sensor 35 mounted on the tank body 212, and the temperature sensor 33 and the pressure sensor 35 are supported and connected to the fixed support member 31. In this way, the temperature sensor 33 can detect the temperature change in the tank body 212 in real time, and the pressure sensor 35 can detect the pressure change in the tank body 212 in real time.

[0060] With the arrangement of the temperature sensor 33 and the pressure sensor 35, the container 1 can remain stable during the heating process through precise temperature control and pressure regulation, thus avoiding safety accidents caused by overheating or overpressure.

[0061] Furthermore, the container 1 is in a cubic shape, and the hydrogen storage tank 21 is in a cylindrical shape and is vertically installed inside the container 1 .

[0062] Preferably, the hydrogen storage tank 21 is made of high-strength, corrosion-resistant material to ensure its safety and stability during use, and the interior of the tank body 212 is specially treated to optimize the storage environment of the hydrogen-absorbing metal particles 211 .

[0063] Furthermore, the hydrogen absorbing metal particles 211 include magnetic material and solid hydrogen storage material, and the magnetic material is uniformly mixed into the solid hydrogen storage material.

[0064] In this embodiment, the hydrogen absorbing metal particles 211 are composed of magnetic materials and solid hydrogen storage materials. According to one embodiment, the solid hydrogen storage material can be a composite hydrate based on magnesium hydride (MgH2), sodium aluminum hydride (NaA1H4), etc. In addition, the magnetic material can be a composite hydrate based on ferrite oxide (FeO x ) or lanthanum manganate (LaMnO3) materials. According to an embodiment, the magnetic material may also include magnetite (Fe3O 4) Or lanthanum manganese (LaMnO X ). In order to realize the solidification of the hydrogen absorbing metal particles 211, they are heated to a specific temperature. During this process, hydrogen reacts chemically with the hydrogen absorbing metal particles 211 to generate solid substances.

[0065] In addition, in order to comprehensively study the hydrogen absorption and desorption processes of the hydrogen absorbing metal particles 211, the present embodiment also deeply understands the influence of temperature on these processes. During the hydrogen absorption process, as the temperature increases, the hydrogen absorption capacity of the hydrogen absorbing metal particles 211 gradually increases until it reaches a saturated state; and during the desorption process, as the temperature increases, the hydrogen absorbing metal particles 211 gradually release the absorbed hydrogen. Therefore, it is very important to determine the temperature range required for the hydrogen absorbing metal particles 211 to absorb saturation and completely release hydrogen, which is of great significance for optimizing the performance of the hydrogen absorbing metal particles 211 and ensuring its stability and safety under different environmental conditions.

[0066] Furthermore, in this embodiment, the shielding layer 216 is made of aluminum. By adding an aluminum shielding layer to the outer layer of the electromagnetic induction heating cable 215, the shielding layer 216 can effectively reduce electromagnetic interference, protect the system from the influence of external electromagnetic fields, and improve the stability and reliability of the system.

[0067] It is worth noting that the electromagnetic induction heating cable 215 of each tank body 212 needs to be protected with aluminum. This measure not only isolates the interference of the electromagnetic field and ensures the normal operation of the cable, but also improves the safety and stability of the entire container 1. The solid-state hydrogen storage container is cleverly and efficiently designed, and it realizes rapid heating and storage of hydrogen through electromagnetic induction heating technology.

[0068] Furthermore, the solid-state hydrogen storage device also includes a power supply and a controller, wherein:

[0069] The power supply is used to supply current to the electromagnetic induction heating cable 215 ; the controller is used to control the supply of current from the power supply to the electromagnetic induction heating cable 215 according to whether hydrogen is stored in or released from the hydrogen absorbing metal particles 211 .

[0070] The electromagnetic induction heating method in this embodiment can achieve precise temperature control of the hydrogen storage material. By adjusting the frequency and intensity of the current, the heating temperature and heating speed can be accurately controlled to ensure that the hydrogen storage material reacts under the optimal temperature conditions. This precise temperature control can not only improve the quality stability of the hydrogen storage container, but also help reduce safety hazards caused by improper temperature.

[0071] Compared with traditional heating methods, electromagnetic induction heating does not require burning fuel, so it does not produce harmful gases and smoke, and has significant environmental advantages. At the same time, due to its high energy conversion efficiency, it can reduce energy waste and meet the requirements of sustainable development.

[0072] In addition, through precise temperature control and pressure regulation, automated and intelligent operation can be achieved. Users can set parameters to achieve remote control and monitoring, and conveniently and flexibly make hydrogen storage containers. This flexible operation method not only improves production efficiency, but also reduces labor costs.

[0073] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
