Description

Technical Field

[0001] The present invention relates to the technical field of solid-state hydrogen storage, and specifically relates to a solid-state hydrogen battery source system and a power system. Background Art

[0002] Hydrogen energy has the characteristics of rich sources, high energy density, green and low-carbon, etc., and has been regarded as the most promising energy source in the 21st century. In the development process of the hydrogen energy industry, the storage and transportation of hydrogen are the key links connecting hydrogen production in the upstream and hydrogen utilization in the downstream. At present, there are three ways to store and transport hydrogen: high-pressure gaseous, liquid, and solid-state. Among them, the solid-state hydrogen storage technology combines hydrogen with hydrogen storage materials through physical or chemical means to achieve hydrogen storage, and has the advantages of high volumetric hydrogen storage density, low pressure, high purity, good safety, long storage time, etc., and is one of the most promising storage methods for commercial development.

[0003] Most of the existing solid-state hydrogen storage containers are made of metal such as steel pipes or steel plates into tubular shells, and then welded with components such as end caps and joints, and multiple hydrogen storage tanks need to be connected in parallel to meet the required hydrogen storage capacity. And because the hydrogen absorption process of the hydrogen storage material is an exothermic process, and the hydrogen release process is an endothermic process, the existing shell-type solid-state hydrogen storage containers usually install a heat exchange liquid flow channel structure inside and connect it with external equipment for heat exchange.

[0004] However, the internal heat exchange liquid flow channel structure design of the existing solid-state hydrogen storage containers often only considers the cooling and heat dissipation problems after hydrogen absorption is completed, but there are problems of inconvenient heating and serious energy consumption during the hydrogen release process; and the parallel connection of multiple solid-state hydrogen storage tanks will lead to a large increase in the number of components. Too many welding parts will not only increase the production cost, but also easily cause various problems such as uneven gas release or airtightness problems, and are not convenient for daily maintenance. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects of the prior art, and provides a solid-state hydrogen battery source system and a power system, which have the advantages of uniform hydrogen absorption and release, good airtightness, convenient heating during the hydrogen release process, and zero energy consumption.

[0006] To achieve the above purpose and other purposes, the present invention is realized by including the following technical solutions: The present invention provides a solid-state hydrogen battery source system, which is characterized in that it includes a storage tank warehouse, including a heat exchange chamber and a pipe layout chamber separated by a fixing plate; a solid-state hydrogen storage tank, fixed in the heat exchange chamber, and its gas inlet and outlet at the top are located in the pipe layout chamber and are connected to the gas circuit of external equipment; a heat exchange rod, arranged at equal intervals with a plurality of the solid-state hydrogen storage tanks, including a connected liquid inlet pipe and a liquid outlet pipe, the connection part of the liquid inlet pipe and the liquid outlet pipe extends into the bottom of the heat exchange chamber, and the liquid inlet of the liquid inlet pipe and the liquid outlet of the liquid outlet pipe are located in the pipe layout chamber and are connected to the liquid circuit of external equipment.

[0011] In one embodiment, reinforcing ribs are arranged between the plurality of fixing structures.

[0012] In one embodiment, a liquid injection hole and an exhaust hole are further formed in the fixing plate. The liquid injection hole is used for injecting a heat-conducting liquid into the heat exchange cavity; a layer of waterproof and breathable film is covered on the exhaust hole.

[0013] In one embodiment, sealing gaskets are arranged on the first mounting hole, the second mounting hole, the liquid injection hole and the exhaust hole, and the cross section of the sealing gasket is T-shaped.

[0014] In one embodiment, a plurality of through holes for communicating the pipe laying cavity with the outside are formed in the tank body of the tank storage bin.

[0015] In one embodiment, a fixing groove is formed in the side wall of the fixing plate, and the fixing plate is fixedly connected to the tank body of the tank storage bin through the fixing groove.

[0016] The present invention also provides a solid hydrogen power system, which is characterized in that the foregoing solid hydrogen battery source system is used to supply hydrogen to the hydrogen-consuming equipment of the power system and perform heat exchange with the hydrogen-consuming equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The structure of the present invention is simple and has a high integration degree. The storage tank chamber is divided into a heat exchange chamber and a pipe layout chamber by a fixing plate, and the solid-state hydrogen storage tank is provided with only one air inlet and outlet, which can avoid the high production cost, uneven gas absorption and release or airtightness problems caused by excessive welding parts. The heat exchange rods of the present invention are arranged at equal intervals with multiple solid-state hydrogen storage tanks, and the connection part of the liquid inlet pipe and the liquid outlet pipe extends into the bottom of the heat exchange chamber, and can be directly connected to the water circuit of a hydrogen-consuming device such as a cooling device or a fuel cell stack for heat exchange, which can reduce the energy consumption of gas release to zero, reduce the energy consumption of the entire power generation system, and ensure uniform temperature in the heat exchange chamber and consistent hydrogen absorption and release temperatures of each solid-state hydrogen storage tank, thereby ensuring the consistency of gas absorption and release.

[0019] 2. The liquid inlet pipe of the heat exchange rod of the present invention is a straight pipe, which can ensure that the heat exchange medium quickly enters the connection part of the liquid inlet pipe and the liquid outlet pipe and preferentially exchanges heat with the heat-conducting liquid at the bottom of the heat exchange chamber. The main body of the liquid outlet pipe is a spiral pipe, which can increase the contact area and contact time between the liquid outlet pipe and the heat-conducting liquid and improve the heat exchange efficiency. The pipe section of the liquid outlet is a straight pipe, which can facilitate the liquid outlet 321 to extend out of the fixing plate.

[0020] 3. The design of the unequal heights of the end faces of the liquid inlet and the liquid outlet of the present invention can be conveniently distinguished by the naked eye to avoid misconnecting the liquid inlet and outlet directions.

[0021] 4. The present invention can conveniently place multiple solid-state hydrogen storage tanks evenly at equal intervals by arranging a plurality of fixing structures in an array at the bottom of the storage tank chamber, so as to ensure that the positions of each solid-state hydrogen storage tank are equivalent to the heat exchange rod located in the center, and at the same time can prevent the solid-state hydrogen storage tank from shaking.

[0022] 5. The present invention can improve the bottom load-bearing capacity of the storage tank chamber by arranging reinforcing ribs between multiple fixing structures.

[0023] 6. The present invention is provided with a liquid injection hole and an exhaust hole on the fixing plate. The liquid injection hole can facilitate the injection of heat-conducting liquid into the heat exchange chamber to increase the thermal conductivity between the heat exchange rod and the solid-state hydrogen storage tank. The exhaust hole can discharge the gas in the heat exchange chamber when the temperature is too high to ensure the safe use of the system.

[0024] 7. The present invention is provided with a T-shaped sealing gasket on the first mounting hole, the second mounting hole, the liquid injection hole and the exhaust hole of the fixing plate, which can further fix the solid-state hydrogen storage tank and the heat exchange rod and play a shock-absorbing role, preventing the solid-state hydrogen storage tank and the heat exchange rod from shaking up and down. The T-shaped design only needs to be plugged down as a whole along each hole during use to achieve installation and fixation, which is convenient to use.

[0025] 8. The present invention is provided with a plurality of through holes for connecting the pipe layout chamber with the outside on the storage tank body of the storage tank chamber, which can facilitate the connection of the pipelines in the pipe layout chamber with external equipment, and can also be used as a handle to facilitate the lifting and moving of the solid-state hydrogen battery source system.

[0040] Embodiment 1

[0041] As Figure 1 shown, the present invention provides a solid hydrogen battery source system 100 for the storage and transportation of hydrogen, including a storage tank warehouse 10 and a solid hydrogen storage tank 20 and a heat exchange rod 30 arranged in the storage tank warehouse 10. The solid hydrogen storage tank 20 is used to place solid hydrogen storage materials, and the solid hydrogen storage materials can be magnesium-based, titanium-based, vanadium-based, rare earth-based and composite hydrogen storage alloys, carbon materials, etc. Please refer to Figure 3 and Figure 4 , a gas inlet and outlet 21 is arranged at the top of the solid hydrogen storage tank 20, and a valve body 41 and a hydrogen manifold pipeline 42 are installed on the gas inlet and outlet 21. The valve body 41 is set according to functional requirements. When the valve body 41 is a one-way valve, it includes a one-way pressure reducing valve for releasing hydrogen from the inside of the solid hydrogen storage tank 20 to the outside, and a one-way hydrogen filling valve for filling hydrogen from the outside of the solid hydrogen storage tank 20 into the inside; the valve body 41 can also be a two-way valve that can be filled and discharged; the hydrogen manifold pipeline 42 is communicated with the gas circuit of external equipment. When the solid hydrogen storage tank 20 stores hydrogen, the hydrogen manifold pipeline 42 is externally connected to a hydrogen production device, and at this time the gas inlet and outlet 21 is an air inlet; when the solid hydrogen storage tank 20 discharges hydrogen, the hydrogen manifold pipeline 42 is externally connected to a hydrogen-consuming device (usually a fuel cell stack, a combustion furnace, etc.), and at this time the gas inlet and outlet 21 is an air outlet. The heat exchange rod 30 is communicated with the liquid circuit of external equipment and is used to perform heat exchange with the solid hydrogen storage tank 20; when the solid hydrogen storage tank 20 stores hydrogen and releases heat, it is used to cool the solid hydrogen storage tank 20, and when the solid hydrogen storage tank 20 needs to discharge hydrogen, it is used to heat the solid hydrogen storage tank 20.

[0042] As Figures 1-4As shown, the storage tank bin 10 can be made of stainless steel material resistant to corrosion and high temperature, such as 304 stainless steel. The storage tank bin 10 can include a bin body 11, a fixing plate 12 and a bin cover 13. The fixing plate 12 is fixedly connected to the upper part of the bin body 11 to form a heat exchange cavity 10a for accommodating and fixing the solid hydrogen storage tank 20 between the fixing plate 12 and the bin body 11. The bin cover 13 is covered on the top of the bin body 11, and a pipe layout cavity 10b for placing pipelines and valve bodies is formed among the bin cover 13, the bin body 11 and the fixing plate 12. A through hole 111 for communicating the pipe layout cavity 10b with the outside of the storage tank bin 10 is formed on the bin body 11. The number and shape of the through holes 111 can be any number and geometric shape required by the design. For example, one through hole 111 can be provided on each of the four side surfaces of the bin body 11 shown in the figure, and the through hole 111 can be in the shape of a rectangle with rounded corners. In addition to facilitating the connection between the pipelines in the pipe layout cavity 10b and external devices, the design of the through hole 111 can also be used as a handle to facilitate lifting and moving the solid hydrogen battery source system 100.

[0043] As Figure 5 As shown, a plurality of fixing structures 112 are arranged at the bottom of the bin body 11. The plurality of fixing structures 112 are arranged in an array for positioning and fixing the solid hydrogen storage tank 20. The positioning is to facilitate the uniform arrangement of the plurality of solid hydrogen storage tanks 20 at equal intervals to ensure that each solid hydrogen storage tank 20 is in a comparable position to the heat exchange rod 30 located at the center, and the fixing is to prevent the solid hydrogen storage tank 20 from shaking. Specifically, the fixing structure 112 can be a hoop protruding from the inner surface of the bottom of the bin body 11, and it can be integrally formed with the bin body 11 to facilitate production and processing. The number of the fixing structures 112 is the same as the number of the solid hydrogen storage tanks 20, and the shape matches the shape of the bottom of the solid hydrogen storage tank 20. For example, an embodiment is shown in the figure where the number of the fixing structures 112 is 4 and the shape is circular. In this embodiment, the inner diameter of each fixing structure 112 is equal to the outer diameter of the bottom of the solid hydrogen storage tank 20 to ensure that the bottom of the solid hydrogen storage tank 20 is clamped by the fixing structure 112 to achieve fixation. The 4 fixing structures 112 are arranged in a matrix array, and the center-to-center connection lines of adjacent two fixing structures 112 form a square.

[0044] Furthermore, in order to improve the load-bearing capacity of the bottom of the bin body 11, reinforcing ribs 113 can be arranged between the plurality of fixing structures 112. The reinforcing ribs 113 are linear and integrally formed with the bin body 11.

[0045] As Figure 6As shown, a plurality of first mounting holes 121 and a second mounting hole 122 are formed in the fixed plate 12. The first mounting holes 121 are circular holes, and the centers of the plurality of first mounting holes 121 correspond to the centers of the plurality of fixing structures 112 one by one, and are used for fixedly mounting the top of the solid hydrogen storage tank 20 to prevent the solid hydrogen storage tank 20 from shaking left and right and up and down. The second mounting hole 122 is arranged at the center of the fixed plate 12 and is used for fixedly mounting the heat exchange rod 30. Moreover, the linear distance between the center of the second mounting hole 122 and the centers of the first mounting holes 121 is equal, so as to ensure that the heat exchange rod 30 uniformly transfers heat to each solid hydrogen storage tank 20, making the hydrogen absorption temperature and hydrogen release temperature of each solid hydrogen storage tank 20 consistent, thereby ensuring the consistency of hydrogen absorption and hydrogen release.

[0046] Furthermore, a liquid injection hole 123 and an exhaust hole 124 are also formed in the fixed plate 12. The liquid injection hole 123 is used for injecting a heat-conducting liquid into the heat exchange cavity 10a, so that the heat-conducting liquid directly fills the remaining space of the heat exchange cavity 10a after the heat exchange rod 30 and the plurality of solid hydrogen storage tanks 20 are installed, thereby increasing the heat conductivity between the heat exchange rod 30 and the solid hydrogen storage tank 20; a layer of waterproof and breathable membrane is covered on the exhaust hole 124, so the exhaust hole 124 cannot inject liquid or drain liquid, and is mainly used for discharging the gas in the heat exchange cavity 10a when the temperature is too high.

[0047] Furthermore, a fixing groove 125 can be formed on the side wall of the fixed plate 12, and the fixed plate 12 can be fixedly connected to the housing 11 through the fixing groove 125.

[0048] Please review Figure 2 , in order to ensure the sealing performance of the first mounting hole 121, the second mounting hole 122, the liquid injection hole 123 and the exhaust hole 124 to prevent the liquid in the heat exchange cavity 10a from flowing out of each hole, sealing gaskets 40 can be arranged on the first mounting hole 121, the second mounting hole 122, the liquid injection hole 123 and the exhaust hole 124. The cross section of the sealing gasket 40 is T-shaped. During use, it can be installed and fixed by simply plugging it tightly downward along each hole as a whole. Moreover, after the sealing gasket 40 is combined with the fixed plate 12, it can further fix the solid hydrogen storage tank 20 and the heat exchange rod 30 and play a shock-absorbing role to prevent the solid hydrogen storage tank 20 and the heat exchange rod 30 from shaking up and down. Specifically, the sealing gasket 40 can be made of silica gel material.

[0049] As Figure 2 and Figure 7As shown, the heat exchange rod 30 can be made of corrosion-resistant, high-temperature-resistant, and highly thermally conductive materials. The heat exchange rod 30 includes a connected liquid inlet pipe 31 and a liquid outlet pipe 32. The connection between the liquid inlet pipe 31 and the liquid outlet pipe 32 extends as far as possible into the bottom of the heat exchange chamber 10a to preferentially exchange heat with the heat-conducting liquid at the bottom; the liquid inlet 311 of the liquid inlet pipe 31 and the liquid outlet 321 of the liquid outlet pipe 32 extend out of the second mounting hole 122 and the sealing gasket 40 thereon to connect with the external device liquid circuit. Specifically, the liquid inlet pipe 31 is a straight pipe to ensure that the heat exchange medium can quickly enter the connection between the liquid inlet pipe 31 and the liquid outlet pipe 32 through the liquid inlet port 311, and preferentially exchange heat with the bottom heat-conducting liquid of the heat exchange chamber 10a; the main body of the liquid outlet pipe 32 is a spiral tube, which can increase the contact area and contact time between the liquid outlet pipe 32 and the heat-conducting liquid, thereby improving the heat exchange efficiency; the pipe section of the liquid outlet port 321 is a straight pipe, so that the liquid outlet port 321 can extend out of the second mounting hole 122 and the sealing gasket 40 thereon.

[0050] Furthermore, since the liquid inlet 311 and the liquid outlet 321 are usually equal-diameter ports and difficult to distinguish with the naked eye, the end faces of the liquid inlet 311 and the liquid outlet 321 can be designed to be unequal in height to facilitate distinction and avoid connecting the wrong liquid inlet and outlet directions. For example, in this embodiment, the end face of the liquid inlet 311 is designed to be higher than the end face of the liquid outlet 321, that is, the pipe section of the liquid inlet pipe 31 extending out of the second mounting hole 122 and the sealing gasket 40 thereon is longer than the pipe section of the liquid outlet pipe 32 extending out of the second mounting hole 122 and the sealing gasket 40 thereon. It should be noted that it is not necessary to distinguish the liquid inlet 311 and the liquid outlet 321 by the height of the end faces. In practice, the liquid inlet 311 and the liquid outlet 321 can also be distinguished by marking on or beside the tube body or other conventional distinguishing methods.

[0051] Please combine Figure 8 When the solid-state hydrogen battery source system 100 is storing hydrogen, since the solid-state hydrogen storage material in the solid-state hydrogen storage tank 20 releases heat when absorbing hydrogen, it is necessary to cool the solid-state hydrogen storage tank 20 with the help of an external cooling device 200 to ensure that it can continue to absorb hydrogen. At this time, the liquid inlet 311 of the heat exchange rod 30 is connected to the cold water outlet of the cooling device 200, and the liquid outlet 321 of the heat exchange rod 30 is connected to the hot water inlet of the cooling device 200. After the cold water of the cooling device 200 enters the heat exchange rod 30, it absorbs the heat released by the solid-state hydrogen storage tank 20 to the heat-conducting liquid, so that the cold water is heated. The heated hot water returns to the cooling device 200 to complete the cooling of the solid-state hydrogen storage tank 20.

[0052] Please combine Figure 9, when the solid hydrogen battery source system 100 supplies hydrogen to the fuel cell stack 300, since the dehydrogenation of the solid hydrogen storage material in the solid hydrogen storage tank 20 requires heat absorption, and the fuel cell stack 300 generates heat during operation, it is usually necessary to dissipate heat through an externally connected cooling device. Therefore, the liquid inlet 311 of the heat exchange rod 30 can be connected to the water outlet of the fuel cell stack 300, and the liquid outlet 321 of the heat exchange rod 30 can be connected to the water inlet of the fuel cell stack 300. Moreover, a water pump, a circulation pump, etc. can be added to the water passage to promote the flow of the heat exchange medium, so that the heat generated during the reaction of the fuel cell stack 300 is brought into the heat exchange rod 30 through the heat exchange medium and transferred to the solid hydrogen storage tank 20 through the heat-conducting liquid in the heat exchange chamber 10a, thereby achieving the effect of heating the solid hydrogen storage tank 20. At the same time, when the solid hydrogen storage tank 20 dehydrogenates, it absorbs the heat of the heat exchange medium in the heat exchange rod 30, realizing the effect of cooling the fuel cell stack 300. Therefore, there is no need to add a water-cooled heat dissipation system to the working system of the fuel cell stack 300, and the solid hydrogen battery source system 100 does not need to add a separate heating device during hydrogen supply, so that the energy consumption can be reduced in a dual-effect manner. The energy consumption during dehydrogenation of the solid hydrogen battery source system 100 can be reduced to zero, and the energy consumption of the entire power generation system can be reduced.

[0053] Embodiment 2

[0054] The present invention also provides a solid hydrogen power system. The power system can be a fuel cell stack, a combustion furnace, an emergency power supply, a hydrogen energy vehicle, etc. The power system uses the solid hydrogen battery source system 100 described in Embodiment 1 to supply hydrogen to its hydrogen-consuming equipment and perform heat exchange with the hydrogen-consuming equipment. Specifically, when the power system is a fuel cell stack or a combustion furnace, the hydrogen-consuming equipment is itself; when the power system is a hydrogen energy vehicle or an emergency power supply, the hydrogen-consuming equipment is the fuel cell of the hydrogen energy vehicle or the emergency power supply.

[0055] Specifically, the air inlet and outlet 21 of the solid hydrogen battery source system 100 is externally connected to the hydrogen inlet of the hydrogen-consuming equipment through the hydrogen manifold pipeline 42 to supply hydrogen to the hydrogen-consuming equipment; at the same time, the liquid inlet 311 of the heat exchange rod 30 of the solid hydrogen battery source system 100 is connected to the water outlet of the hydrogen-consuming equipment, and the liquid outlet 321 of the heat exchange rod 30 is connected to the water inlet of the hydrogen-consuming equipment to realize the heat exchange between the hydrogen-consuming equipment and the solid hydrogen storage tank 20.

[0056] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
