Description

Technical Field

[0001] The invention relates to the field of hydrogen energy hydrogen cylinder transportation, and more specifically to a solid hydrogen storage and transportation device. Background Art

[0002] Among flammable gases, hydrogen has a lower ignition energy. A cylinder is a pressure vessel for storing and transporting hydrogen. A cylinder is a pressure-bearing device that is dangerous. Its notable characteristics are that the use environment is constantly changing and the operator has a certain degree of instability, which leads to more complex and demanding requirements than other pressure vessels. Once a gas cylinder leaks, fire or poisoning often occurs, or even a catastrophic accident occurs, causing serious property damage, personal injury, and environmental pollution. Hydrogen cylinders often need to be transported back and forth within the factory area where they are used to achieve their storage, use, and transportation functions. There are many safety requirements for the storage and transportation of hydrogen cylinders. For example, hydrogen cylinders should be properly fixed to prevent them from being overturned or hit; hydrogen cylinders must not be placed near heat sources and should be at least 10 meters away from open flames; gas cylinders filled with gases that can cause combustion or explosion after contact with hydrogen (such as oxygen cylinders) cannot be transported in the same vehicle;

[0003] At present, the metal hydride hydrogen storage technology is generally used in the market. It is a solid-state hydrogen storage technology. Compared with high-pressure hydrogen bottles and liquid hydrogen, metal hydride hydrogen storage has low pressure, safety and flexibility. However, the process of metal hydride reacting with hydrogen to convert hydrogen into solid hydrogen is an exothermic process, which needs to be dissipated. The existing hydrogen storage device does not dissipate heat sufficiently, which will lead to a high temperature inside the hydrogen storage device, which may easily lead to insufficient hydrogen absorption by the metal hydride or slow chemical reaction, thereby affecting the hydrogen absorption performance of the metal hydride. In addition, the hydrogen storage material will expand and shrink in volume during the hydrogen absorption and desorption process. Repeated hydrogen absorption and dehydrogenation cycles will cause it to pulverize, and the pulverized hydrogen storage alloy powder is easy to move and enrich internally, which will lead to uneven distribution of expansion stress during the hydrogen absorption process, causing the hydrogen storage tank to deform or even rupture.

[0004] A hydrogen cylinder safety storage and transportation device similar to patent number CN202311388859.X comprises: a cart body, on which a clamping mechanism, a sliding mechanism, an identification mechanism and a detection mechanism are arranged, the clamping mechanism is used to grab and fix the hydrogen cylinder, the sliding mechanism is used to adjust the contact position between the clamping mechanism and the hydrogen cylinder, the identification mechanism is used to identify whether the hydrogen cylinder has a risk of explosion according to the state of the clamping mechanism, and the detection mechanism is used to automatically track the heat source according to the surrounding environment of the hydrogen cylinder and generate an electronic fence. The advantages of the present invention are: flexible, simple, fast, convenient, safe and reliable operation, maintenance-free, able to overcome the harsh environment on site, and transmit the safety environment data to the control room in real time and accurately, which can be read at any time and stored in various forms.

[0005] However, the hydrogen storage device does not dissipate heat sufficiently, which will lead to a high temperature inside the hydrogen storage device, which may easily cause the metal hydride to absorb hydrogen insufficiently or the chemical reaction to be slow, thereby affecting the hydrogen absorption performance of the metal hydride. Summary of the invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that the hydrogen storage device does not dissipate heat sufficiently, which leads to a high temperature inside the hydrogen storage device, easily causing insufficient hydrogen absorption by the metal hydride, or a slow chemical reaction, thereby affecting the hydrogen absorption performance of the metal hydride.

Specific implementation method one:

[0041] like Figure 1 — Fig.13 As shown, a solid-state hydrogen storage and transportation device includes a storage box 1, a hydrogen storage bottle 5 is arranged in the storage box 1, a plurality of hydrogen storage alloy blocks 6 and a plurality of porous air guide tubes 2 are arranged in the hydrogen storage bottle 5, a heat dissipation fin 3 is arranged on the outer side of the hydrogen storage bottle 5, a cooling tube 7 is arranged on the upper plate of the heat dissipation fin 3, and the heat dissipation fin 3 and the cooling tube 7 are automatically fitted and spot-welded and fixed by a combination device 11.

[0042] The working principle and beneficial effects of this embodiment are as follows: the hydrogen storage alloy block 6 comprises hydrogen storage alloy powder, a thermal conductor and a resin material, the mass proportion of the hydrogen storage alloy powder is between 80% and 98%, the mass proportion of the thermal conductor is between 1% and 10%, and the mass proportion of the resin material is between 1% and 10%;

[0043] The unit weight of the hydrogen storage alloy compact 6 is between 0.1kg and 50kg, and the shape can be cylinder, cuboid, cube, or prism;

[0044] The hydrogen storage alloy powder is titanium AB 2 type, titanium AB type, rare earth system, titanium vanadium solid solution, magnesium-based hydrogen storage alloy; the thermal conductor is copper fiber, aluminum fiber, graphene, flake graphite, carbon nanotube, aluminum oxide, magnesium oxide, zinc oxide, aluminum nitride, boron nitride or silicon carbide; the resin is WACKER soft resin or hard resin;

[0045] When the hydrogen storage alloy powder and the thermal conductor in the hydrogen storage alloy compact 6 are mixed and dispersed, a double planetary mixer, a V-type mixer or a high-speed stirring mixer is used for stirring;

[0046] The porous air guide tube 2 is made of powder metallurgy sintered porous material, and the filtering accuracy is between 20μm and 100μm;

[0047] Since hydrogen storage alloy releases heat when absorbing hydrogen and absorbs heat when charging hydrogen, the heat release power and heat absorption power when absorbing and desorbing hydrogen are positively correlated with the absorption and desorption rate. Therefore, an adjustment switch is set at the inlet of the cooling pipe to control the water flow rate. Hot water is passed when absorbing hydrogen, and cold water is passed when desorbing hydrogen. The hot and cold water are automatically switched to hot and cold water according to the charging and discharging mode using the control switch. The water inlet flow rate is adjusted according to the heat release or heat absorption power to improve the energy efficiency of the system. In addition, the fan power of the lower side wall is also adjusted according to the hydrogen charging and desorption rate. The fan is equipped with a resistance wire and can provide hot air. Cold air is sent when absorbing hydrogen, and hot air is sent when desorbing hydrogen. The above parts are controlled through the control system;

[0048] The filling process of the hydrogen storage alloy briquette of the present invention is simple and efficient, and the hydrogen alloy powder and the thermal conductor are directly stirred and mixed, which ensures that the hydrogen storage alloy powder material is fully in contact with the thermal conductor, and the two are tightly combined by the resin material, and have good thermal conductivity and overall firmness, avoiding the internal movement and enrichment of the hydrogen storage alloy powder; by arranging heat dissipation fins on the side of the hydrogen storage bottle and cooling pipes on the side of the heat dissipation fins, the heat dissipation fins effectively transfer the heat of the hydrogen storage bottle and increase the heat exchange area, and at the same time the cooling pipes dissipate heat from the heat dissipation fins, thereby playing the effect of cooling the hydrogen storage bottle, improving the heat dissipation efficiency, and effectively improving the hydrogen storage performance of the hydrogen storage alloy briquette.

[0053] The filling process of the hydrogen storage alloy briquette of the present invention is simple and efficient, and the hydrogen alloy powder and the thermal conductor are directly stirred and mixed, which ensures that the hydrogen storage alloy powder material is fully in contact with the thermal conductor, and the two are tightly combined by the resin material, so that the hydrogen storage alloy powder material has good thermal conductivity and overall firmness, and the internal movement and enrichment of the hydrogen storage alloy powder are avoided.

The side fixing frame 33 is fixed to the side end of the operating processing frame 12. The side fixing frame 33 is fixed with a height driver 34. The height driver 34 drives the longitudinal slide 35 to slide longitudinally in the side fixing frame 33 through a synchronous belt and a screw.

The reversal drive chain 28 is attached to the top platform 29 and engages with the reversal transport sprocket 24. The top platform 29 is fixed to the operating processing frame 12.

[0067] The working principle and beneficial effects of this embodiment are as follows: the transport carrier 23 which is transported in a circular manner sequentially adds the heat dissipation fins 3 and the cooling tubes 7 when passing through the adding frame 13, and sequentially passes through the rotating welding table 15, the cooling box 1 16, the secondary rotating welding table 17 and the cooling box 2 18; the effects of welding, cooling, welding and cooling are achieved, and the equipment is prevented from being damaged due to excessive temperature;

[0068] When the carrier 23 carrying the heat dissipating fins 3 and the cooling tubes 7 passes through the welding stop frame 30, the transport is stopped by the limit feedback, and the pressing hydraulic press 31 drives the pressing rotating plate 32 to press down to control the height position of the heat dissipating fins 3 and the cooling tubes 7 to prevent the position from tilting or skewing during the welding process.
