Description

Technical Field

[0001] The present invention belongs to the technical field of solid-state hydrogen storage, and in particular relates to a solid-state hydrogen storage and release device. Background Art

[0002] Hydrogen energy is an extremely pure energy source with the advantage of zero pollution, and is widely used in various energy-consuming industries. In terms of stability, hydrogen is not stable enough to be stored and transported. There are two commonly used methods. The first is to convert hydrogen from a gaseous state to a liquid and store it in a pressure vessel to achieve the purpose of storage and transportation. However, this method cannot solve the safety problem, and many measures are needed to ensure the stability of hydrogen. The second method is to react hydrogen with a hydrogen storage alloy to form a compound that is extremely cold at room temperature and pressure, which facilitates subsequent storage and transportation. When hydrogen is needed, the compound is heated to release the hydrogen. In this way, the hydrogen is separated from the hydrogen storage alloy, and the hydrogen storage alloy can be reused to achieve the storage and release of hydrogen. The existing method of storing hydrogen in powder form has been replaced. The main reason is that it is impossible to ensure that the hydrogen storage alloy powder reacts fully with hydrogen. Stirring and disturbance methods are required, which are cumbersome to operate and difficult to ensure safety. Moreover, after the hydrogen is released, some powder will be carried with it, and the hydrogen needs to be filtered and purified, which is difficult and has high maintenance costs in the later stage.

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0034] The present invention discloses a solid-state hydrogen storage and release device, such as Figure 1-9As shown, the hydrogen storage tank 100 includes a temperature control system and a hydrogen storage tank body 100. The hydrogen storage tank body 100 is vertically arranged and includes an upper tank cover 108, a lower tank cover 104, a first hydrogen storage seat 101, and a second hydrogen storage seat 102. The upper tank cover 108 and the lower tank cover 104 are respectively installed at the upper and lower ends of the hydrogen storage tank body 100. An upper air pipe 109 and a lower air pipe 105 are respectively constructed on the upper tank cover 108 and the lower tank cover 104. A second control valve 110 is installed on the upper air pipe 109, a first control valve 106 is installed on the lower air pipe 105, a second bypass pipe 111 is constructed on the upper air pipe 109, and a first bypass pipe 107 is constructed on the lower air pipe 105. According to the installation conditions of the on-site pipelines, the present invention can choose to use the ends of the lower gas pipe 105 and the upper gas pipe 109 to connect the gas pipelines, and close the second bypass pipe 111 and the first bypass pipe 107; or it can choose to use the ends of the second bypass pipe 111 and the first bypass pipe 107 to connect the gas pipelines, and close the ends of the upper gas pipe 109 and the lower gas pipe 105. The number of the first hydrogen storage seat 101 and the second hydrogen storage seat 102 of the present invention is multiple, and the first hydrogen storage seat 101 and the second hydrogen storage seat 102 are connected together by rotating alternately in the vertical direction, and the adjacent first hydrogen storage seat 101 and the second hydrogen storage seat 102 are connected by the connecting seat 103. The first hydrogen storage seat 101 of the present invention has a first temperature adjustment channel, and the second hydrogen storage seat 102 has a second temperature adjustment channel. The temperature adjustment system is connected to the first temperature adjustment channel of each first hydrogen storage seat 101 and the second temperature adjustment channel of each second hydrogen storage seat 102. All of the second hydrogen storage seats 102 of the present invention are connected to a transmission member via a temperature control system, and the transmission member can be driven to synchronously rotate the second hydrogen storage seats 102 0°-180° along the axis of the hydrogen storage tank body 100. The working principle and advantages of the present invention are: the present invention uses the hydrogen storage tank body 100 to store and release hydrogen, because the hydrogen storage tank body 100 is composed of a plurality of first hydrogen storage seats 101 and a plurality of second hydrogen storage seats 102 assembled alternately.When storing hydrogen, all the second hydrogen storage seats 102 are adjusted so that they rotate along the axis of the hydrogen storage tank body 100 at a certain angle, preferably 90 degrees. In this way, hydrogen enters the hydrogen storage tank body 100 from the lower gas pipe 105 and passes through the alternating first hydrogen storage seat 101 and the second hydrogen storage seat 102 in the vertical direction. Since the angle of the second hydrogen storage seat 102 is adjusted, the flow path of the hydrogen is adjusted, that is, the adjusted second hydrogen storage seat 102 creates a certain obstruction to the flow of hydrogen, thereby playing a role in buffering the hydrogen and slowing down the flow. The hydrogen gas can be fully adsorbed by the surfaces of the first hydrogen storage seat 101 and the second hydrogen storage seat 102 at a high speed; the hydrogen gas that is not adsorbed is discharged from the hydrogen storage tank body 100 through the upper air pipe 109, and this part of the hydrogen gas can be forcibly pumped into the hydrogen storage tank body 100 through the lower air pipe 105 by an air pump for forced circulation to ensure the complete absorption of the hydrogen gas; during the hydrogen storage process, the cooling medium is supplied to each of the first hydrogen storage seat 101 and the second hydrogen storage seat 102 by the temperature control system to remove the heat generated during the hydrogen storage process by heat exchange, thereby avoiding the situation where the temperature is too high and hinders the hydrogen storage. When hydrogen is released, all the second hydrogen storage seats 102 are adjusted back to their original positions so that the flow path of hydrogen is unobstructed, and the heating medium is supplied to each of the first hydrogen storage seat 101 and the second hydrogen storage seat 102 by the temperature control system, and the lower air pipe 105 is opened, and the first hydrogen storage seat 101 and the second hydrogen storage seat 102 release the stored hydrogen, and the hydrogen is supplied to the gas-using equipment through the flow path by the lower air pipe 105; In summary, the present invention is extremely safe for storing and releasing hydrogen, and has the characteristics of fully absorbing and quickly releasing hydrogen, which improves the safety of hydrogen storage and the safety of operation, and reduces the difficulty of operation and maintenance costs. The present invention can appropriately increase the number of the first hydrogen storage seat 101 and the second hydrogen storage seat 102 according to the demand for hydrogen storage.

[0035] As a preferred embodiment of the present invention, Figure 5 As shown, the first hydrogen storage seat 101 includes an annular first seat body 1011, and a plurality of first hydrogen storage and release grids 1012 are spaced apart inside the first seat body 1011. These first hydrogen storage and release grids 1012 are arranged side by side, and a first hydrogen flow channel 1013 is formed between two adjacent first hydrogen storage and release grids 1012. The first temperature adjustment channel of this embodiment is constructed in the first seat body 1011 and each first hydrogen storage and release grid 1012, and a first medium inlet joint 1017 and a first medium outlet joint 1018 are arranged on the outer peripheral wall of the first seat body 1011 relative to each other, wherein the first medium inlet joint 1017 and the first medium outlet joint 1018 are both connected to the first temperature adjustment channel, and the first medium inlet joint 1017 and the first medium outlet joint 1018 are connected to the temperature adjustment system. Figure 3 、 4As shown, the first temperature-regulating channel of this embodiment includes an annular medium channel 1014 constructed within the first seat 1011. Two truncation blocks 1016 are disposed opposite each other within the annular medium channel 1014. These two truncation blocks 1016 divide the annular medium channel 1014 into two semi-annular channels, which are respectively connected to a first medium inlet connector 1017 and a first medium outlet connector 1018. A medium through-channel 1015 is constructed within each first hydrogen storage and release grid 1012. Each of the two ends of each medium through-channel 1015 is respectively connected to the two semi-annular channels, thereby forming a complete channel with the two semi-annular channels and all the medium through-channels 1015. This allows the medium to flow through this complete channel, thereby cooling or heating the first hydrogen storage seat 101. During hydrogen storage in this embodiment, the cooling medium flows through the first temperature-regulating channel, and hydrogen flows through the first hydrogen flow channel 1013, reacting with the outer surface of the first hydrogen storage and release grid 1012, thereby achieving the purpose of hydrogen storage. During hydrogen release, the heating medium flows through the first temperature regulating channel, and the heated first hydrogen storage and release grid 1012 releases the hydrogen thereon. The hydrogen enters the first hydrogen flow channel 1013 and is then discharged from the hydrogen storage tank 100 .

[0036] As a preferred embodiment of the present invention, Figure 5 As shown, the second hydrogen storage seat 102 has a similar structure to the first hydrogen storage seat 101. The second hydrogen storage seat 102 includes an annular second seat body 1021. A plurality of second hydrogen storage and release grids 1022 are spaced apart within the second seat body 1021. These second hydrogen storage and release grids 1022 are arranged side by side, and a second hydrogen flow channel 1023 is formed between two adjacent second hydrogen storage and release grids 1022. The second temperature control channel of this embodiment is constructed within the second seat body 1021 and each second hydrogen storage and release grid 1022. A second medium inlet connector 1024 and a second medium outlet connector 1025 are arranged on the outer peripheral wall of the second seat body 1021. The second medium inlet connector 1024 and the second medium outlet connector 1025 are both connected to the second temperature control channel, and the second medium inlet connector 1024 and the second medium outlet connector 1025 are connected to the temperature control system. The structure of the second temperature control channel of this embodiment is the same as that of the first temperature control channel, and will not be repeated here. The hydrogen storage and release principles of the second hydrogen storage seat 102 of this embodiment are the same as those of the first hydrogen storage seat 101. In this embodiment, when storing hydrogen, the second hydrogen storage seat 102 is rotated 90 degrees so that the second hydrogen flow channel 1023 and the first hydrogen flow channel 1013 are perpendicular to each other, forming a flow blocking channel 129, that is, Figure 9As shown in the form, in the process of hydrogen flowing through the hydrogen storage tank body 100, the flow of hydrogen is hindered, thereby slowing down the flow rate of hydrogen, so that the hydrogen can fully react with the outer surface of the first hydrogen storage grid 1012 and the second hydrogen storage grid 1022. In this embodiment, when hydrogen is released, the second hydrogen storage seat 102 is rotated back to its original position so that the second hydrogen flow channel 1023 and the first hydrogen flow channel 1013 are aligned one by one to form a guide channel 128, that is, Figure 8 In the embodiment shown, hydrogen flows unimpeded through the hydrogen storage tank 100, thereby promoting rapid release of hydrogen and its rapid departure from the hydrogen storage tank 100. The connection base 103 of this embodiment includes a connection ring 1031. A connection flange 1032 extending radially inward is configured on the inner wall of the connection ring 1031. The corresponding end surfaces of the adjacent first and second base bodies 1011, 1021 contact the connection flange 1032. The connection ring 1031 is sleeved over the ends of the first and second base bodies 1011, 1021 that are adjacent to each other, and is rotatably connected to the first and second base bodies 1011, 1021.

[0037] As a preferred embodiment of the present invention, Figure 11 As shown, a plurality of grooves 1019 are constructed on the vertical outer surfaces of the first hydrogen storage grid 1012 and the second hydrogen storage grid 1022. These grooves 1019 are arranged vertically at intervals and each groove 1019 extends along the length of the first hydrogen storage grid 1012 or the second hydrogen storage grid 1022. The cross-section of the grooves 1019 is sawtooth-shaped, and the sharp corners of the sawtooth shape of the grooves 1019 face downward. The working principle and advantages of this embodiment are: during the hydrogen storage process, since hydrogen enters the hydrogen storage tank 100 through the lower gas pipe 105, the hydrogen is blocked by the grooves 1019 as it flows through the hydrogen storage tank 100, achieving a slow flow effect, allowing the hydrogen sufficient time to react with the outer surfaces of the first hydrogen storage grid 1012 and the second hydrogen storage grid 1022. In addition, the presence of the grooves 1019 increases the surface area of ​​the first hydrogen storage grid 1012 and the second hydrogen storage grid 1022, thereby increasing the hydrogen storage capacity. In the present embodiment, during the release of hydrogen, the hydrogen is released, and then passes vertically downward through the hydrogen storage tank body 100 and is discharged from the lower gas pipe 105. During this process, since the sharp corners of the sawtooth shape of the groove 1019 are facing downward, this will not hinder the exhaust, allowing the hydrogen to be smoothly discharged from the hydrogen storage tank body 100.

[0038] As a preferred embodiment of the present invention, in order to facilitate the installation and alignment of the first hydrogen storage seat 101 and the second hydrogen storage seat 102 and to ensure the rotation stability of the second hydrogen storage seat 102, the upper ends of the first hydrogen storage seat 101 and the second hydrogen storage seat 102 are raised upward, and the lower ends of the two are recessed upward, and the raised portion of the second hydrogen storage seat 102 is adapted to the recessed portion of the adjacent first hydrogen storage seat 101.

[0039] As a preferred embodiment of the present invention, Figure 2 As shown, the temperature control system includes a first communicating pipe and a second communicating pipe that are connected to each other. The first communicating pipe is connected to each first hydrogen storage seat 101, and the second communicating pipe is connected to each second hydrogen storage seat 102. Figure 6 As shown, the first connecting pipeline of this embodiment includes a connecting pipe A112 and a connecting pipe B116, which are relatively arranged on the outside of the hydrogen storage tank body 100; a plurality of joint pipes A113 are spaced apart on the connecting pipe A112, and a plurality of joint pipes B117 are spaced apart on the connecting pipe B116, each joint pipe A113 is connected to the corresponding first medium inlet joint 1017, and each joint pipe B117 is connected to the corresponding first medium outlet joint 1018. In this embodiment, a conducting joint A114 and a conducting joint B118 are respectively constructed on the connecting pipe A112 and the connecting pipe B116, a third control valve 115 is installed on the conducting joint A114, and a fourth control valve 119 is installed on the conducting joint B118 to facilitate the inflow and outflow of the medium. Figure 7As shown, the second connecting pipe of this embodiment includes a connecting pipe C120 and a connecting pipe D122, which are relatively arranged on the outside of the hydrogen storage tank body 100; a plurality of joint pipes C121 are spaced apart on the connecting pipe C120, and a plurality of joint pipes D123 are spaced apart on the connecting pipe D122, each joint pipe C121 is connected to the corresponding second medium inlet joint 1024, and each joint pipe D123 is connected to the corresponding second medium outlet joint 1025. Moreover, the upper end of the connecting pipe C120 of this embodiment is connected to the connecting pipe A112 through the first hose 126, and the upper end of the connecting pipe D122 is connected to the connecting pipe B116 through the second hose 127. In this way, the medium entering the connecting pipe A112 enters the connecting pipe C120 through the first hose 126, and enters each first hydrogen storage seat 101 and each first hydrogen storage seat 101 respectively, thereby cooling or heating all the first hydrogen storage seats 101 and all the second hydrogen storage seats 102, and then flows into the connecting pipe B116 and the connecting pipe D122 respectively, and finally flows out through the conducting joint B118. The transmission member of this embodiment includes a transmission wheel 125, which is respectively connected and fixed to the lower ends of the connecting pipe C120 and the connecting pipe D122 through two connecting arms 124. In this way, when the transmission wheel 125 is driven to rotate a predetermined angle, the transmission wheel 125 drives the second connecting pipe to rotate a predetermined angle through the connecting arm 124, thereby achieving the purpose of the second connecting pipe driving all the second hydrogen storage seats 102 to rotate synchronously.

[0040] As a preferred embodiment of the present invention, in order to improve the hydrogen storage capacity and efficiency and facilitate transportation and other operations, as Figure 12-14As shown, there are multiple hydrogen storage tanks 100 arranged in multiple rows, with the hydrogen storage tanks 100 in each row mounted on a fixed frame at intervals.

The inlet and outlet of each temperature control system are connected to the first medium pipe 600 and the second medium pipe 700, respectively. Specifically, multiple connector pipes F501 are spaced apart on the first manifold 500, each of which is connected to the corresponding upper air pipe 109.

In this embodiment, a plurality of joint pipes G601 are spaced apart on the first medium pipe 600. These joint pipes G601 are respectively connected to corresponding conductive joints A114. A plurality of joint pipes H701 are spaced apart on the second medium pipe 700. These joint pipes H701 are respectively connected to corresponding conductive joints B118. The fixed frame of this embodiment includes an upper frame 200 and a lower frame 300. The upper and lower ends of the hydrogen storage tank body 100 are respectively fixedly connected to the upper frame 200 and the lower frame 300. The transmission wheel 125 of the transmission member of each hydrogen storage tank body 100 is rotatably mounted on the lower frame 300. The transmission wheels 125 in the same row can be connected by a chain. In this way, by driving the chain, the transmission wheel 125 drives the corresponding second hydrogen storage seat 102 to rotate.
