Description

Technical Field

[0001] This invention relates to the field of storage device technology, and more specifically, to a small-scale heated solid hydrogen storage device. Background Technology

[0002] Existing solid hydrogen storage devices are small hydrogen storage cylinders, which are simple bottle structures with inlets and outlets. When hydrogen needs to be stored, it is stored inside the cylinder through the inlet and outlet; when hydrogen is needed, it is discharged from the cylinder. During hydrogen storage, the hydrogen storage material inside the cylinder is in an exothermic state. Due to the large diameter of the storage material, its thermal conductivity is not very good, resulting in poor heat dissipation and slow hydrogen storage. When hydrogen is discharged, the storage material in the cylinder is in an endothermic state. Due to the large diameter of the storage material, the internal temperature drops, and it cannot make good contact with the outside, causing a significant decrease in the output rate. Summary of the Invention

[0003] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] To at least partially solve the above problems, the present invention provides a small heating type solid hydrogen storage device, comprising: a hydrogen storage container connected inside an outer sleeve, a heat exchange cavity formed between the hydrogen storage container and the outer sleeve, and the two ends of the heat exchange cavity being connected to a medium inlet and a medium outlet on the outer sleeve, respectively.

[0005] Optionally, the outer sleeve includes a cylinder, a medium inlet and a medium outlet are disposed on the cylinder, two assembled end plates are fixed relatively inside the cylinder, the two ends of the hydrogen storage container are sealed and connected to the two assembled end plates, and a heat exchange chamber is formed between the hydrogen storage container, the outer sleeve and the two assembled end plates.

[0006] Optionally, the hydrogen storage container includes multiple hydrogen storage tubes, each with its ends sealed and fixedly connected to two assembly end plates. One end of each hydrogen storage tube is inserted into a hydrogen inlet cavity formed between one assembly end plate and one end cap of the cylinder. The other end of each hydrogen storage tube is inserted into a hydrogen outlet cavity formed between another assembly end plate and another end cap of the cylinder. The hydrogen inlet cavity and the hydrogen outlet cavity are respectively connected to the hydrogen inlet and hydrogen outlet at both ends of the cylinder.

[0007] Optionally, both ends of the hydrogen storage tube are sealed with tube caps.

[0008] Optionally, multiple baffles are spaced apart inside the heat exchange chamber. The multiple baffles are located between the medium inlet and the medium outlet. The multiple baffles are sealed to the inner wall of the cylinder. Multiple hydrogen storage tubes are inserted through the tube holes of the multiple baffles. A first flow groove is provided on the baffle.

[0009] Optionally, the first flow channel is disposed at the outer edge of the baffle plate, and the first flow channels of two adjacent baffle plates are respectively disposed on the upper side and the lower side of the inner side of the cylinder, so that the medium entering the heat exchange chamber from the medium inlet flows to the medium outlet in an S-shaped flow path.

[0010] Optionally, the outer edge of the baffle plate is further provided with two second flow grooves, which are located on both sides of the first flow groove. The two second flow grooves are respectively arranged on the left side and the right side inside the cylinder.

[0011] Optionally, the opening size of the second flow channel is smaller than the opening size of the first flow channel.

[0012] Optionally, the second flow channels of two adjacent turbulence baffles are staggered.

[0013] Compared with the prior art, the small heating solid hydrogen storage device provided by the present invention forms a heat exchange cavity between the hydrogen storage container and the outer sleeve. The two ends of the heat exchange cavity are connected to the medium inlet and the medium outlet on the outer sleeve, respectively. The heat exchange medium can be introduced into the heat exchange cavity through the medium inlet, so that the heat exchange medium exchanges heat with the hydrogen storage container, thereby regulating the temperature of the hydrogen storage container. This makes the hydrogen storage or hydrogen output of the hydrogen storage container no longer limited by temperature, reduces the influence of temperature on the hydrogen storage or hydrogen output rate, and allows the capacity of the hydrogen storage container to be relatively large.

[0014] This invention solves the problem that ordinary hydrogen storage devices cannot store or discharge properly due to excessively low or high temperatures by controlling the temperature of the hydrogen storage container, so that solid hydrogen storage will no longer be affected by temperature in terms of storage and discharge.

[0015] The present invention has a larger capacity than the original hydrogen storage cylinder, and the input and output speed is also relatively faster.

[0028] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0030] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0031] The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0032] Example 1

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the small heating solid hydrogen storage device provided by the present invention includes: a hydrogen storage container 1, which is connected inside an outer sleeve 2, and a heat exchange chamber is formed between the hydrogen storage container 1 and the outer sleeve 2. The two ends of the heat exchange chamber are respectively connected to the medium inlet and the medium outlet on the outer sleeve 2.

[0034] The working principle and technical effects of the above technical solution are as follows:

[0035] In the small-scale heated solid hydrogen storage device provided by this invention, the hydrogen storage container 1 is connected inside the outer sleeve 2, forming a heat exchange chamber between the hydrogen storage container 1 and the outer sleeve 2. The two ends of the heat exchange chamber are respectively connected to the medium inlet and the medium outlet on the outer sleeve. The heat exchange medium can be input into the heat exchange chamber through the medium inlet, flow in the heat exchange chamber, and be discharged through the medium outlet. During the flow of the heat exchange medium, heat exchange can be performed on the hydrogen storage container 1, thereby regulating the temperature of the hydrogen storage container 1. This makes the hydrogen storage or discharge of the hydrogen storage container 1 no longer limited by temperature, reducing the influence of temperature on the hydrogen storage or discharge rate, and allowing the capacity of the hydrogen storage container to be relatively large. By controlling the temperature of the hydrogen storage container 1, the problem that ordinary hydrogen storage devices cannot store or discharge normally due to too low or too high temperatures is solved, so that solid hydrogen storage will no longer be affected by temperature in terms of storage and discharge.

[0036] The outer sleeve 2 includes a cylinder 3 and an assembly end plate 4. The medium inlet and medium outlet are located on the cylinder 3. Two assembly end plates 4 are fixed relatively inside the cylinder 3. The medium inlet and medium outlet are located between the two assembly end plates 4. The structures of the two assembly end plates 4 can be the same or different, as long as they meet the installation requirements at both ends of the hydrogen storage container 1. The two ends of the hydrogen storage container 1 are sealed and connected to the two assembly end plates 4. The space between the hydrogen storage container 1, the outer sleeve 2, and the two assembly end plates 4 is a heat exchange chamber.

[0037] The hydrogen storage container 1 includes hydrogen storage tubes, preferably thin-walled stainless steel round tubes for easy temperature adjustment. Multiple hydrogen storage tubes are provided, with both ends sealed and fixedly connected to two assembly end plates 4. One end of each tube is inserted into a hydrogen inlet chamber formed between one assembly end plate 4 and one end cap of the cylinder 3. The other end of each tube is inserted into a hydrogen outlet chamber formed between another assembly end plate 4 and the other end cap of the cylinder 3. The hydrogen inlet and outlet chambers are connected to the hydrogen inlet and outlet at both ends of the cylinder 3, respectively. With the hydrogen outlet closed, hydrogen to be stored can be input into the hydrogen inlet chamber through the hydrogen inlet, and the hydrogen can then enter the hydrogen storage tubes through one end of each tube for storage. The hydrogen inlet is then closed. When discharging hydrogen, the hydrogen outlet is opened, allowing hydrogen to enter the hydrogen outlet chamber through the multiple hydrogen storage tubes and exit through the hydrogen outlet.

[0038] Both ends of the hydrogen storage tube are sealed with caps, allowing hydrogen to be introduced into a single hydrogen storage tube. When the amount of hydrogen is small, it is not necessary to use all the hydrogen storage tubes. In this case, the cap at one end of the hydrogen storage tube can be opened to introduce hydrogen into the preset hydrogen storage tube.

[0039] Example 2

[0040] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the small heating solid hydrogen storage device provided by the present invention has multiple turbulence baffles 5 spaced apart in the heat exchange chamber. The multiple turbulence baffles 5 are all located between the medium inlet and the medium outlet. The multiple turbulence baffles 5 are sealed and connected to the inner wall of the cylinder 3. Multiple hydrogen storage tubes are all inserted through the tube holes of the multiple turbulence baffles 5. The turbulence baffles 5 are provided with a first flow groove 6.

[0041] The working principle and technical effects of the above technical solution are as follows:

[0042] In the small-scale heating solid hydrogen storage device provided by the present invention, multiple turbulence baffles 5 are arranged at intervals in the heat exchange cavity, and the multiple turbulence baffles 5 are all located between the medium inlet and the medium outlet. After the heat exchange medium enters the heat exchange cavity through the medium inlet, it effectively exchanges heat at different positions of multiple hydrogen storage tubes, so that the medium flows fully in the heat exchange cavity. Furthermore, a first flow groove 6 is provided on the turbulence baffle 5, so that the heat exchange medium can pass through the heat exchange area formed between two adjacent turbulence baffles 5 in sequence through the first flow groove 6. This allows the hydrogen in multiple hydrogen storage tubes to be regulated in temperature, improves the heat exchange effect and heat exchange efficiency, and improves the hydrogen input and output effect.

[0043] The first flow channel 6 is located at the outer edge of the baffle plate 5. The first flow channels 6 of two adjacent baffle plates 5 are respectively located on the upper side and the lower side inside the cylinder 3, so that the medium entering the heat exchange chamber from the medium inlet flows to the medium outlet in an S-shaped flow path.

[0044] Placing two adjacent baffles 5 in a relative position ensures that the first flow channels 6 of the two adjacent baffles 5 are staggered and opposite, so that the medium entering the heat exchange chamber from the medium inlet flows in an S-shaped path to the medium outlet. For example, the path of the heat exchange medium is down-up-down-up-down-up-down-up, and the heat exchange medium presents a continuous S-shaped path flow, so that the heat exchange medium can fully contact different positions of multiple hydrogen storage tubes and improve the uniformity of heat exchange of multiple hydrogen storage tubes.

[0045] Two second flow channels 7 are also provided at the outer edge of the baffle plate 5. The two second flow channels 7 are located on both sides of the first flow channel 6. The two second flow channels 7 are respectively arranged on the left side and the right side inside the cylinder 3.

[0046] Each of the aforementioned baffles 5 is provided with two second flow channels 7, which are used in conjunction with the first flow channels 6 to adjust the path of the heat exchange medium. Since the first flow channels 6 of the multiple baffles 5 are used to make the heat exchange medium flow in an S-shaped path, the heat exchange medium moves in the up and down direction, and the contact effect between the heat exchange medium and the multiple hydrogen storage tubes in the middle of the inner side of the cylinder 3 is better. In order to improve the contact effect between the heat exchange medium and the multiple hydrogen storage tubes at the left and right ends of the inner side of the cylinder 3, each of the aforementioned baffles 5 is provided with two second flow channels 7, so that in addition to flowing along the S-shaped path, the heat exchange medium also has a second and a third flow path, that is, it flows through the two second flow channels 7 on the left and right sides of the multiple baffles 5, forming two heat exchange medium flow paths on the left and right sides inside the cylinder 3, ensuring that the medium can travel through all the hydrogen storage tubes and improving the uniformity of heat exchange for multiple hydrogen storage tubes.

[0047] The opening size of the second flow channel 7 is smaller than that of the first flow channel 6. Since the heat exchange medium flows in a continuous S-shaped path, it comes into contact with a large number of hydrogen storage tubes. In order to ensure sufficient heat exchange effect, the first flow channel 6 is larger and the second flow channel 7 is smaller.

[0048] The second flow channels 7 of two adjacent turbulence baffles 5 are staggered, and multiple second flow channels 7 are staggered so that the heat exchange medium flowing through the second and third flow paths on both sides also has a certain up-and-down undulation effect when flowing, ensuring that the heat exchange medium can fully contact the hydrogen storage tubes on both sides and improve the heat exchange effect.

[0049] Example 3

[0050] like Figure 8 , Figure 9 and Figure 10As shown, the small-scale heated solid hydrogen storage device provided by the present invention has seven baffles 5. The seven baffles 5 are arranged sequentially from the medium inlet to the medium outlet as baffle I 501, baffle II 502, baffle III 503, baffle IV 504, baffle V 505, baffle VI 506, and baffle VII 507. An electric push rod I 8 is fixed to a mounting end plate 4, and the movable end of the electric push rod I 8 is connected to a horizontal mounting shaft 9. The baffles I 501, II 502, III 503, and VII 507 are... 7 are all fixed on the horizontal mounting shaft 9; partitions IV 504, V 505 and VI 506 are all slidably connected to the horizontal mounting shaft 9; the fixed end of electric push rod II 10 is fixed on partition III 503, and the movable end of electric push rod II 10 is connected to partition IV 504; the fixed end of electric push rod III 11 is fixed on partition IV 504, and the movable end of electric push rod III 11 is connected to partition V 505; the fixed end of electric push rod IV 12 is fixed on partition VII 507, and the movable end of electric push rod IV 12 is connected to partition VI 506.

[0051] The working principle and technical effects of the above technical solution are as follows:

[0052] In the small-scale heated solid hydrogen storage device provided by this invention, because the initial temperature of the heat exchange medium entering the heat exchange chamber is relatively high, the heat exchange effect of the heat exchange medium on the tube body near the medium inlet of the cylinder 3 is better. However, when the heat exchange medium flows to the tube body near the medium outlet of the cylinder 3, the temperature of the heat exchange medium is lower than its initial temperature when it enters the medium inlet. In order to improve the heat exchange effect, the above-mentioned structure is set up, and seven turbulence baffles 5 are set. The seven turbulence baffles 5 are baffle I 501, baffle II 502, baffle III 503, baffle IV 504, baffle V 505, baffle VI 506 and baffle VII 507 in the direction from the medium inlet to the medium outlet. Baffles I 501, baffle II 502, baffle III 503, baffle IV 504, baffle V 505, baffle VI 506 and baffle VII 507 are the turbulence baffles 5. After the heat exchange chamber is filled with heat exchange medium,

[0053] First, control the electric push rod Ⅲ11 to start. The electric push rod Ⅲ11 controls the partition V505 to move towards the partition IV504. When the partition V505 is tightly attached to the partition IV504, the partition V505 and the partition IV504 block each other's second flow groove 7 and first flow groove 6. At this time, the heat exchange medium cannot flow through the partition V505 to the second flow groove 7 and first flow groove 6 of the partition IV504.

[0054] Then, the electric push rod IV12 is started. The electric push rod IV12 controls the partition VI506 to move towards the partition VII507. When the partition VI506 and the partition VII507 are tightly fitted together, the partition VI506 and the partition VII507 block each other on the second flow groove 7 and the first flow groove 6 of each other. At this time, the heat exchange medium cannot flow through the partition VI506 to the second flow groove 7 and the first flow groove 6 of the partition VII507.

[0055] Finally, the electric push rod II10 is activated. The electric push rod II10 controls the partitions IV504 and V505, which are in a closed state, to move towards the partitions VI506 and VII507, which are in a closed state. At this time, the heat exchange medium between partitions V505 and VI506 cannot flow out. Under the pushing action of the electric push rod II10, the heat exchange medium between partitions V505 and VI506 can be pressurized, thereby increasing the temperature of the heat exchange medium between partitions V505 and VI506 to a certain extent. This improves the heat exchange effect of the heat exchange medium with the tube body near the medium outlet of the cylinder 3 after the temperature is increased.

[0056] In addition, after the electric push rod I8 is started, it can drive the partitions I501, II502, III503 and VII507 to slide on the inner wall of the cylinder 3 through the horizontal mounting shaft 9. It can also drive the partitions IV504, V505 and VI506 to move through the cooperation of the electric push rods II10, III1 and IV12, and slide on the multiple hydrogen storage tubes. This can scrape off the dust or impurities on the cylinder 3 and the multiple hydrogen storage tubes, and clean them regularly to prevent scaling when there is a large amount of heat exchange medium flowing, which would affect the heat exchange effect.

[0057] Example 4

[0058] like Figure 1 , Figure 2 and Figure 3As shown, the small-scale heated solid hydrogen storage device provided by the present invention has an input check valve on the medium inlet, so that the external medium can only be fed into the cylinder 3 through the medium inlet; the partitions I 501, II 502 and III 503 have the same structure, all being annular partition structures, and each partition I 501, II 502 and III 503 is connected to a swirl component 13, the swirl component 13 including a sleeve ring 14, the sleeve ring 14 being rotatably connected to partition I 501, partition II 502 or partition III 503, the outer ring surface of the sleeve ring 14 slidingly fitting on the inner wall of the cylinder 3, and the side of the sleeve ring 14 near the medium inlet being fixedly connected to... An internal gear ring 15 is connected to two gears 16 on its inner side. The two gears 16 are fixed to one end of two shafts 17. The middle of the two shafts 17 rotates at both ends of a bearing frame 18. The bearing frame 18 is fixed on partition I 501, partition II 502, or partition III 503. A worm gear 19 is rotatably connected to the bearing frame 18. A rotating wheel 20 is fixed at the center of the worm gear 19. The rotating wheel 20 rolls and frictionally engages with the inner wall of the cylinder 3. The two ends of the worm gear 19 are engaged with two worm wheels 21 one by one. The two worm wheels 21 are fixedly connected to the two shafts 17 one by one. Multiple swirl impellers 22 are evenly and fixedly connected around the side of the sleeve ring 14 away from the medium inlet.

[0059] When partitions I 501, II 502, and III 503 slide within the cylinder 3, they drive the swirling component 13 to move. The rotating wheel 20 within the swirling component 13 contacts the inner wall of the cylinder 3 and can rotate during relative motion. The rotation of the rotating wheel 20 drives the worm 19 to rotate, which in turn meshes with and drives two worm gears 21. The rotation of the two worm gears 21 drives two axles 17 to rotate, which in turn drives two gears 16 to rotate. The meshing of the two gears 16 during rotation... The rotating internal gear ring 15 drives the sleeve ring 14 to rotate on partition I 501, partition II 502, or partition III 503. When the sleeve ring 14 rotates, it drives multiple swirling impellers 22 to rotate and circulate, thus improving the uniformity of the heat exchange medium distribution within the heat exchange cavity and enhancing the heat exchange effect and efficiency. Furthermore, the rotation of the sleeve ring 14 allows for better breaking down and cleaning of the dirt on the inner wall of the cylinder 3, improving the cleaning effect without requiring additional power.

[0060] A rack is fixed on the inner wall of the cylinder 3, and the length direction of the rack is parallel to the axis of the cylinder 3. The rotating wheel 20 is a gear structure, and the rotating wheel 20 is meshed with the rack. When the rotating wheel 20 moves, it contacts the rack and rotates, making the rotation of the rotating wheel 20 more stable.
