Description

Technical Field

[0001] The present invention relates to the technical field of new energy, and specifically to a hydrogen storage device. Background Art

[0002] Hydrogen storage is a key link for safely and efficiently storing and releasing hydrogen, which directly affects the feasibility and economy of hydrogen energy applications.

[0003] Currently, the mainstream technical routes for hydrogen storage include high-pressure gaseous hydrogen storage, cryogenic liquid hydrogen storage, and solid-state hydrogen storage;

[0004] High-pressure gaseous hydrogen storage: Compress hydrogen in a storage tank under high pressure (35 - 70 MPa);

[0005] Cryogenic liquid hydrogen storage: Cool hydrogen to -253 °C to liquefy it and store it in a vacuum-insulated container;

[0006] Solid-state hydrogen storage: Store hydrogen through physical adsorption or chemical reaction with materials (metals / non-metals).

[0007] Solid-state hydrogen storage technology stores hydrogen in a solid state (such as metal hydrides, porous materials), solving the bottlenecks of traditional gaseous / liquid hydrogen storage in terms of density, safety, and energy consumption.

[0008] Solid-state hydrogen storage materials are divided into two major categories: physical adsorption type and chemical hydrogen storage type. The latter is industrialized faster. Chemical hydrogen storage materials include magnesium-based materials and rare earth-based / titanium-manganese-based alloys, etc. The magnesium-based materials or rare earth-based / titanium-manganese-based alloy particles are installed in the corresponding hydrogen storage shell. When hydrogen is introduced into the shell, hydrogen reacts with the material to form metal hydrides, thereby storing hydrogen in a solid state. The process of forming metal hydrides is accompanied by heat release, and a cooling device will be provided; when releasing hydrogen, heat it to a certain high temperature, and the metal hydrides release hydrogen.

[0009] Hydrogen absorption is an exothermic reaction, and hydrogen release requires heat absorption. In the thermal cycle, the material expands and contracts repeatedly, resulting in the accumulation of thermal stress, causing the material particles to agglomerate and reducing the mass transfer efficiency.

[0010] In view of this, we propose a hydrogen storage device. Summary of the Invention

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0049] Two embodiments provided by the present invention

[0050] Embodiment 1

[0051] A hydrogen storage device:

[0052] Please refer to Figures 1 to 8 , which includes a housing 100. A partition A 500 is fixedly arranged on one side of the housing 100, and a heating structure 300 is arranged on the other side of the housing 100.

[0053] The heating structure 300 includes a partition B 301. The partition B 301 is fixedly arranged on the other side of the housing 100. The housing 100, the partition A 500 and the partition B 301 form a closed mechanism for containing chemical hydrogen storage materials. Fill the magnesium-based material into the housing 100 from the feeding port of the housing 100, and then close the feeding port. The magnesium-based material is in the closed mechanism, and the magnesium-based material is not filled completely, leaving a space for the magnesium-based material to expand.

[0054] An intake air passage 101 is fixedly arranged at the hydrogen intake port of the housing 100, and an exhaust air passage 102 is fixedly arranged at the hydrogen outlet of the housing 100. Valves are arranged on both the intake air passage 101 and the exhaust air passage 102. The valve can adopt a bottle mouth valve. The bottle mouth valve plays a crucial role in the solid hydrogen storage mechanism. It not only controls the inlet and outlet of hydrogen, but also integrates various functions, such as a main shut-off valve, a one-way valve, a pressure release device and an overflow valve, etc. During hydrogen storage, the bottle mouth valve of the intake air passage 101 is opened, and the bottle mouth valve of the exhaust air passage 102 is closed. Hydrogen enters the housing 100 from the intake air passage 101. The hydrogen entering the housing 100 reacts with the magnesium-based material to generate metal hydride, thereby storing hydrogen in a solid state. When releasing hydrogen, the bottle mouth valve of the exhaust air passage 102 is opened, and the bottle mouth valve of the intake air passage 101 is closed. Heat the metal hydride to >300 °C. After heating, the metal hydride releases hydrogen, and the released hydrogen is discharged from the exhaust air passage 102.

[0055] Inside the housing 100, there are multiple heat conducting rods 400 arranged row by row. One end of each heat conducting rod 400 is rotatably connected to the partition A 500 through a sealed bearing A 700, and the other end of the heat conducting rod 400 is rotatably connected to the partition B 301 through a sealed bearing A 700. The heat conducting rod 400 is rotatable relative to the housing 100. A plurality of extension pieces A 401 are fixedly arranged on the outer periphery of the heat conducting rod 400 in an annular array; the extension pieces A 401 and the heat conducting rod 400 are made of copper alloy material. The heat generated by the heating structure 300 is transferred into the magnesium-based material through the heat conducting rod 400 and the extension pieces A 401. The contact surface between the heat conducting rod 400 and the extension pieces A 401 and the magnesium-based material is larger than that of a simple external heating, so that the magnesium-based material can be heated up faster.

[0056] On the side of the partition A 500 facing away from the housing 100, there is a cooling structure 200, which includes a front liquid tank 202 and a heat exchange tank 201. The front liquid tank 202 and the heat exchange tank 201 are fixedly connected to the housing 100 in sequence. A plurality of liquid guiding ports 2021 are opened on the front liquid tank 202. A multi-stage branch pipe 203 is fixedly arranged on the outer wall of the front liquid tank 202 where the plurality of liquid guiding ports 2021 are located. An inlet pipe 204 is fixedly arranged at the inlet end of the multi-stage branch pipe 203. A proportional flow valve 205 is arranged on the inlet pipe 204. The outlet of the front liquid tank 202 is communicated with the inlet of the heat exchange tank 201. An outlet pipe 206 is fixedly arranged at the outlet of the heat exchange tank 201. The external cooling medium is input into the front liquid tank 202 through the inlet pipe 204 and the multi-stage branch pipe 203 by a corresponding liquid pump. The cooling medium is discharged from the outlet of the front liquid tank 202, enters the heat exchange tank 201 through the inlet of the heat exchange tank 201, and finally the cooling medium is discharged from the outlet pipe 206. The heat released during hydrogen storage is absorbed by the flow of the cooling medium in the front liquid tank 202 and the heat exchange tank 201.

[0057] A plurality of connecting rods 207 are longitudinally and rotatably arranged in the inner cavity of the pre-liquid tank 202. A rotating piece 208 is fixedly arranged on the connecting rod 207. A fixed piece 209 is fixedly arranged on the inner cavity wall of the pre-liquid tank 202 corresponding to the rotating piece 208. A bent spring 210 is arranged between the rotating piece 208 and the fixed piece 209. The two ends of the spring 210 are fixedly connected to the rotating piece 208 and the fixed piece 209 respectively. The liquid guide port 2021 is inclined. The liquid guide flow direction of the liquid guide port 2021 forms an angle with the side of the rotating piece 208 facing the liquid guide port 2021. The cooling medium discharged from the multi-stage branch pipe 203 enters the inner cavity of the pre-liquid tank 202 from the liquid guide port 2021. Through the guiding of the cooling medium by the liquid guide port 2021, the impactful cooling medium impacts on the rotating piece 208 at a certain angle, so that the impact force of the cooling medium acts more on the rotating piece 208. After the rotating piece 208 is stressed, it drives the connecting rod 207 to rotate, and the spring 210 is compressed. By changing the flow rate of the cooling medium entering the liquid inlet pipe 204 irregularly through the proportional flow valve 205, the impact force of the cooling medium impacting on the rotating piece 208 is in a changing state, which also makes the spring 210 bounce under the changing impact force, driving the rotating piece 208 to rotate and adjust slightly.

[0058] The cooling medium transported by an external liquid pump has a certain impact force. The cooling medium entering the pre-liquid tank 202 impacts on the rotating piece 208. The impactful cooling medium transfers kinetic energy to the rotating piece 208, causing the rotating piece 208 to deflect, thereby driving the heat conduction rod 400 to rotate within a small range. After the kinetic energy is transferred, the cooling medium enters the heat exchange tank 201 from the pre-liquid tank 202. The cooling medium starts to fill upward from the bottom of the heat exchange tank 201 until it is discharged from the liquid outlet pipe 206 connected to the heat exchange tank 201.

[0059] A plurality of transmission structures 600 are arranged between the partition A 500 and the pre-liquid tank 202 and the heat exchange tank 201. The plurality of transmission structures 600 are longitudinally arranged in sequence corresponding to multiple rows of heat conduction rods 400. The transmission structure 600 includes a connecting shaft 60, one end of the connecting shaft 601 is rotatably connected to the pre-liquid tank 202 through a sealed bearing B 800, one end of the connecting shaft 601 is fixedly connected to the connecting rod 207, the other end of the connecting shaft 601 is fixedly connected to one end of the heat conduction rod 400, a double-link synchronous pulley 602 is sleeved on the connecting shaft 601, and two adjacent double-link synchronous pulleys 602 are power-connected through a synchronous belt 603. Two adjacent synchronous belts 603 are staggered. During the process that the rotating piece 208 is continuously rotating and adjusting its position, the connecting rod 207 rotates accordingly, the connecting shaft 601 rotates along with the connecting rod 207, and multiple connecting shafts 601 in the same row rotate under the action of the double-link synchronous pulley 602 and the synchronous belt 603, driving the heat conduction rod 400 to rotate. The extension piece A 401 rotates along with the heat conduction rod 400, so that the heat conduction rod 400 and the extension piece A 401 stir the magnesium-based material.

[0060] The present invention provides a connecting rod 207, a rotating plate 208, a fixed plate 209, a spring 210, a connecting shaft 601, a double synchronous pulley 602, a synchronous belt 603, a heat-conducting rod 400 and an extension plate A401. It has the advantages of conveying a cooling medium while utilizing the impact of the cooling medium to drive the heat-conducting rod 400 and the extension plate A401 to rotate and stir the magnesium-based material, thereby reducing the agglomeration of material particles and solving the problem of material particle agglomeration and reduced mass transfer efficiency.

[0061] See also Figure 6 and Figure 9 Four guide rods 212 are provided on the rotating plate 208. One end of the guide rods 212 is fixedly connected to the fixed plate 209. The four guide rods 212 are distributed around the spring 210 to form a limiting mechanism for the spring 210. Without affecting the compression and elasticity of the spring 210, the spring 210 is limited and kept in a bent shape. The other end of the guide rods 212 is fixedly provided with a limit block 213. The limit block 213 limits the rotational position of the rotating plate 208, and the rotating plate 208 does not disengage from the guide rods 212.

[0062] A plurality of guide plates 211 are fixedly provided on the inner wall of the front liquid tank 202. The guide plates 211 are located below the rotating plate 208. The guide plates 211 are tilted. The guide plates 211 guide the cooling medium so that the cooling medium entering the front liquid tank 202 and hitting the rotating plate 208 will not affect the movement of the rotating plate 208 below as much as possible during the downstream process.

[0063] Example 2

[0064] Based on the technical content of the above embodiment 1, another embodiment is proposed, a hydrogen storage device:

[0065] See also Figure 2 、 Figure 3 and Figure 10 A plurality of embedding grooves 3011 are provided on the side of the partition B301 facing away from the outer shell 100, and the heating section of the heater body 302 is embedded in the embedding groove 3011. The shell of the heater body 302 is fixedly connected to the partition B301 by bolts. The heater body 302 and the partition B301 are detachable. When a heater body 302 is damaged, the damaged single heater body 302 can be directly removed, and it is more convenient to replace a new heater body 302.

[0066] See also Figure 11 and Figure 12, the heat conducting rod 400 is provided with an inner cavity. The inner cavity of the extension piece A401 communicates with the inner cavity of the heat conducting rod 400. An extension piece B402 is inserted through the outer end of the extension piece A401 facing away from the heat conducting rod 400. A limiting piece 403 is fixedly arranged at one end of the extension piece B402 extending into the inner cavity of the extension piece A401. The extension piece B402 and the limiting piece 403 form a pressure stabilizing mechanism. The extension piece B402 and the limiting piece 403 are made of copper alloy material. A sealing strip is arranged on the outer periphery of the limiting piece 403, and the sealing strip abuts against the inner cavity wall of the extension piece A401. The inner cavity of the extension piece A401 separated by the limiting piece 403 and the inner cavity of the heat conducting rod 400 are in a sealed state. After the heater main body 302 works, the generated heat is transferred to the heat conducting rod 400. The gas pressure in the inner cavity of the heat conducting rod 400 is constant. When the gas is heated, it will expand. In order to stabilize the pressure in the inner cavity of the heat conducting rod 400, the expanded gas pushes the limiting piece 403 to move along the inner cavity of the extension piece A401, pushing the extension piece B402 to move outward relative to the extension piece A401, further increasing the contact surface with the magnesium-based material through the extension piece B402, and the magnesium-based material can be heated up faster. And the protruding extension piece B402 plays a role in puncturing the magnesium-based material. For the agglomeration of magnesium-based material particles, the protruding extension piece B402 destroys the agglomerated magnesium-based material particles, and cooperates with the rotation of the heat conducting rod 400 and the extension piece A401 in the first embodiment to easily stir the destroyed agglomerated magnesium-based material particles. When not heated, the gas cools down and no longer expands. In order to stabilize the pressure in the inner cavity of the heat conducting rod 400, the limiting piece 403 moves back along the inner cavity of the extension piece A401, driving the extension piece B402 to retract into the inner cavity of the extension piece A401.

[0067] By providing the heat conducting rod 400, the extension piece A401, the extension piece B402 and the limiting piece 403, the present invention has the advantages that the protruding extension piece B402 further increases the contact surface with the magnesium-based material, and the protruding extension piece B402 plays a role in puncturing the magnesium-based material, and the protruding extension piece B402 destroys the agglomerated magnesium-based material particles.

[0068] Working principle: During hydrogen storage, the bottle valve of the intake channel 101 is opened, and the bottle valve of the outlet channel 102 is closed. Hydrogen enters the housing 100 from the intake channel 101. The hydrogen that enters the housing 100 reacts with the magnesium-based material to form metal hydride, thereby storing hydrogen in a solid state. Along with the hydrogen storage process, heat is released. The external cooling medium is input into the pre-liquid tank 202 by the corresponding liquid pump through the liquid inlet pipe 204 and the multi-stage branch pipe 203. Through the guiding of the cooling medium by the liquid guiding port 2021, the impactful cooling medium impacts on the rotating piece 208 at a certain angle. After the rotating piece 208 is stressed, it drives the connecting rod 207 to rotate, compressing the spring 210. The flow rate of the cooling medium entering the liquid inlet pipe 204 is changed irregularly through the proportional flow valve 205, resulting in the impact force of the cooling medium impacting on the rotating piece 208 being in a changing state. That is, the spring 210 bounces under the changing impact force, driving the rotating piece 208 to rotate slightly for adjustment; during the process that the rotating piece 208 is constantly rotating and adjusting its position, the connecting rod 207 rotates accordingly, and the connecting shaft 601 rotates along with the connecting rod 207. Multiple connecting shafts 601 in the same row rotate under the action of the double-pulley synchronous belt wheel 602 and the synchronous belt 603, driving the heat conducting rod 400 to rotate. The extension piece A401 rotates along with the heat conducting rod 400, causing the heat conducting rod 400 and the extension piece A401 to stir the magnesium-based material. The cooling medium is discharged from the liquid outlet of the pre-liquid tank 202 and enters the heat exchange tank 201 through the liquid inlet of the heat exchange tank 201. Finally, the cooling medium is discharged from the liquid outlet pipe 206, and the heat released during hydrogen storage is absorbed through the flow of the cooling medium in the pre-liquid tank 202 and the heat exchange tank 201.

[0069] During hydrogen release, the bottle valve of the outlet channel 102 is opened, and the bottle valve of the intake channel 101 is closed. The heat generated after the heater body 302 works is transferred to the heat conducting rod 400. The gas pressure in the inner cavity of the heat conducting rod 400 is constant. The gas expands when heated. To stabilize the pressure in the inner cavity of the heat conducting rod 400, the expanded gas pushes the limiting piece 403 to move along the inner cavity of the extension piece A401, pushing the extension piece B402 to move outward relative to the extension piece A401. The contact surface with the magnesium-based material is further increased through the extension piece B402, enabling the magnesium-based material to heat up faster. Moreover, the protruding extension piece B402 punctures the magnesium-based material, and for the agglomeration situation of the magnesium-based material particles, the protruding extension piece B402 destroys the agglomerated magnesium-based material particles. The destroyed agglomerated magnesium-based material particles are easily stirred by the rotating heat conducting rod 400 and the extension piece A401 during hydrogen storage; the released hydrogen is discharged from the outlet channel 102.

[0070] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
