Description

Technical Field

[0001] This invention relates to the field of heat exchange and hydrogen energy utilization technology, specifically to a material rotation mechanism. Background Technology

[0002] Energy shortages, environmental pollution, and global climate change have made the development of clean, efficient, safe, and sustainable energy sources an urgent priority, with hydrogen energy gaining increasing attention from various countries. In the 21st century, the engine industry has developed rapidly; however, gasoline and diesel engines remain the primary choices. Both gasoline and diesel are non-renewable resources. To mitigate the negative impacts of petroleum resource scarcity and reduce air pollution and engine emissions, alternative fuels for engines are needed, and hydrogen energy is currently the most ideal clean fuel. As environmental protection measures become increasingly stringent worldwide, hydrogen-powered engines, due to their energy efficiency and low emissions, have become a focus of engine research and development and have begun commercialization. Traditional hydrogen energy utilization mostly involves directly burning gaseous hydrogen to obtain thermal and kinetic energy. However, gaseous hydrogen is difficult to store and transport, and directly using the hydrogen energy obtained from combustion in power systems can cause knocking, instability, and other problems affecting safe operation.

[0003] Metallic hydrogen storage materials have the ability to store hydrogen and, under certain temperature and pressure conditions, can release the stored hydrogen, making the storage, transportation, and use of hydrogen safer and more reliable. However, current technologies struggle to achieve rapid heat exchange in metallic hydrogen storage materials, which hinders their instantaneous hydrogen absorption and release, making it difficult for them to complete the hydrogen absorption and release transition in a short time.

[0008] Specifically, heat exchange fins are provided in both the hot medium channel and the cold medium channel.

[0009] Specifically, the material rotation mechanism further includes multiple medium inlets and outlets; the medium inlets and outlets pass through the housing and are connected to the hot medium channel and cold medium channel respectively via corresponding hoses and / or rigid pipes.

[0010] Specifically, an insulation layer is provided between each adjacent heat medium channel and cold medium channel; an insulation layer is provided between the outermost heat exchange medium channel and the shell.

[0011] Specifically, the first cavity of the housing is provided with a rotor slot and a stator coil slot; the rotor slot is located in the center of the first cavity, and the stator coil slot is arranged around the outside of the rotor slot.

[0012] Specifically, the driving device includes a squirrel-cage rotor disposed in a rotor slot and a stator coil disposed in a stator coil slot; the squirrel-cage rotor includes a support body, a spindle, and column bars; the spindle of the squirrel-cage rotor is connected to an inner cover disposed at the top or bottom of a first cavity via a second bearing; the support body is wheel-shaped, the spindle is disposed at the center of the support body, and the column bars are symmetrically disposed around the spindle along the support body; a limit block is disposed on the support body; at least one shift fork is disposed on the support body; each shift fork corresponds to a shift fork pin; or, at least one electromagnetic absorbing plate is disposed on the support body; each electromagnetic absorbing plate corresponds to a rotating plate magnet.

By moving the first and second rotating plates disposed in the material interlayer, the heat exchange medium for the metal hydrogen storage material in the material interlayer can be freely selected. Since the amount of metal hydrogen storage material in the material interlayer is small and easy to move, rapid heat exchange of the metal hydrogen storage material can be achieved, solving the problem of the difficulty in rapid heat exchange of metal hydrogen storage materials in the prior art, realizing instantaneous heat exchange of metal hydrogen storage materials, and improving the efficiency of hydrogen absorption and desorption of metal hydrogen storage materials.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0019] Example 1 provides a material rotation mechanism, such as Figure 1 As shown, it can be used for hydrogen absorption and desorption reactions of metal hydrides. In Figure 1 The material rotation mechanism shown includes a housing 101, which may include a first cavity and a second cavity.

[0020] Figure 2 for Figure 1 A cross-sectional view along the AA direction. (e.g.) Figure 2As shown, both the heat exchange medium channels and the material jacket 102 are annular and arranged alternately. The heat exchange medium channels consist of symmetrically arranged hot medium channels 103 and cold medium channels 104. An insulation layer 116 is provided between each adjacent hot medium channel 103 and cold medium channel 104. An insulation layer 116 is also provided between the outermost heat exchange medium channel and the shell 101.

Thrust bearings 111 are respectively provided at the other ends of the first rotating plate 105 and the second rotating plate 106. A first bearing 108 is provided in the center of the connecting rod 107. At least one shift fork pin 109 is also provided on the connecting rod 107. The driving device drives the first rotating plate 105 and the second rotating plate 106 to move along the inner wall of the material interlayer 102 via the shift fork pin 109 and the connecting rod 107. Figure 8 This is a structural schematic diagram of the combined device including various rotating plates and connecting rods 107.

Figure 3 As shown, floating carbon sealing strips 112 are respectively provided on both sides of the first rotating plate 105 and the second rotating plate 106. A floating carbon sealing ring 113 is provided at one end of the floating carbon sealing strip 112 near the connecting rod 107.

[0024] Figure 4 A schematic diagram of the structure of housing 101 is shown. Figure 5 It shows Figure 4 A cross-sectional view along the BB direction. The first cavity in housing 101 is used to house the drive unit. Specifically, as shown... Figure 1As shown, the first cavity of the housing 101 is provided with a rotor slot and a stator coil slot 117. The rotor slot is located in the center of the first cavity, and the stator coil slot 117 is arranged around the outside of the rotor slot. The drive device disposed in the first cavity of the housing 101 includes a squirrel-cage rotor 118 disposed in the rotor slot and a stator coil 119 disposed in the stator coil slot 117. Figure 6 This is a schematic diagram of the structure of the squirrel cage rotor 118. Figure 7 This is a top view of the squirrel cage rotor 118. Figure 6 and Figure 7 As shown, the squirrel-cage rotor 118 includes a support body 120, a spindle 121, and column bars 122. The support body 120 is wheel-shaped, the spindle 121 is located in the center of the support body 120, and the column bars 122 are symmetrically arranged around the spindle 121 along the support body 120. A limit block 123 is provided on the upper part of the support body 120 for controlling the rotation angle of the squirrel-cage rotor and the various rotating plates that rotate with the squirrel-cage rotor. At least one shift fork 124 is provided on the lower part of the support body 120, and the shift fork 124 corresponds one-to-one with the shift fork pin 109. In terms of the installation of the squirrel-cage rotor, the spindle 121 of the squirrel-cage rotor 118 can be connected to the inner cover 126 located on the top of the first cavity through a second bearing 125.

[0025] The front view of the material rotating mechanism provided in Example 1 is as follows: Figure 1 As shown below. Figure 1 Taking the outermost material interlayer as an example, the process of heat exchange between the material rotating mechanism and the metal hydride is introduced: exist Figure 1 In the outermost material interlayer 102, the right half of the metal hydrogen storage material is in a hydrogen absorption and heat release state. Immersing the wall of the right half of the metal hydrogen storage material in high-pressure, low-temperature liquid methane allows this part of the metal hydrogen storage material to successfully complete the hydrogen absorption and heat release. The hydrogen to be absorbed enters from the second hydrogen inlet / outlet 130 located at the top of the material interlayer 102 and extending out of the shell. After hydrogen absorption, the high-pressure, low-temperature liquid methane is converted into high-temperature, high-pressure gaseous methane and discharged from the material rotation mechanism through the corresponding medium inlet / outlet 114. At the same time, high-pressure, low-temperature liquid methane continuously replenishes the cold medium channel 104.

[0026] The left half of the metal hydrogen storage material in the outermost material interlayer 102 is in a hydrogen release and heat absorption state. Immersing the left half of the metal hydrogen storage material interlayer in high-temperature, low-pressure gaseous methane allows this part of the metal hydrogen storage material to successfully complete the hydrogen release and heat absorption. The released hydrogen gas exits from the first hydrogen inlet / outlet 129 located at the top of the material interlayer 102 and extending out of the shell. After the hydrogen release is completed, the high-temperature, low-pressure gaseous methane is converted into low-temperature, low-pressure liquid methane, which is discharged from the material rotation mechanism through the corresponding medium inlet / outlet 114. At the same time, high-temperature, low-pressure gaseous methane continuously replenishes the heat medium channel 103.

[0027] when Figure 1 When the metal hydrogen storage materials in the left and right parts of the material interlayer 102 change their working state, the first rotating plate 105 and the second rotating plate 106 are simultaneously rotated 180° by the driving device, so as to change the heat exchange environment of the metal hydrogen storage materials in the left and right parts to meet the temperature requirements of the metal hydrogen storage materials changing their working state. Example 2

[0028] Example 2 provides another material rotation mechanism, such as Figure 9 As shown, Figure 10 This is the corresponding three-dimensional view. The material rotation mechanism in Embodiment 2 is largely the same as the material rotation mechanism in Embodiment 1, but the first cavity for setting the drive device is located in the lower part of the housing 101, and the drive device and... Figure 1 The drive mechanisms are largely the same, the difference being... Figure 9 The drive unit is equipped with electromagnetic chucks 133, which can be permanent magnets or electrically controlled electromagnets. Correspondingly, rotating plate magnets 132 are provided on the connecting rods 107 that connect each rotating plate. Each rotating plate magnet 132 corresponds to one electromagnetic chuck 133. When the rotor in the drive unit rotates, the magnetic force between the electromagnetic chucks 133 and the rotating plate magnets 132 drives each rotating plate to move along the inner wall of the material interlayer 102. Figure 9 In the material rotation mechanism shown, the lower structure of the rotating plate is similar to... Figure 1 The rotating plate is different; see details. Figure 11 As shown. In Figure 11 In the middle, the lower part of the rotating plate is equipped with both a thrust bearing 111 and a rotating plate magnet 132. In practical applications, magnetic levitation can be used instead. Figure 11 The thrust bearing is located in the middle. Furthermore, to facilitate the rotation of the rotating plate, a rotary joint 136 can be provided at the lower end of the second bearing 125. The rotary joint 136 is connected to the first hydrogen inlet / outlet 129, the second hydrogen inlet / outlet 130, and the medium inlet / outlet 114 located below. Each inlet / outlet can be connected to its corresponding channel or interlayer via its corresponding rigid pipe 134 and flexible pipe 131. Specifically, the upper first hydrogen inlet / outlet 129 and second hydrogen inlet / outlet 130 are connected to the upper part of the material interlayer 102 via rigid pipes and flexible pipes, respectively; the lower part of the material interlayer 102 is connected to the lower first hydrogen inlet / outlet 129 and second hydrogen inlet / outlet 130 via flexible pipes and rigid pipes, respectively. The metal hydride in the material interlayer 102 needs to be replaced periodically after repeated use. Therefore, it can be... Figure 9 The material rotation mechanism shown is equipped with a metal hydride inlet and outlet 135 for sucking out or pushing metal hydrides.

[0029] The heat exchange method for the metal hydrogen storage material disposed within the material jacket 102 can be direct heat exchange, indirect heat exchange, or a combination of both. When using direct heat exchange, small holes are provided between the hot medium channel 103 and the material jacket 102, and between the cold medium channel 104 and the material jacket 102. High-temperature hydrogen is used as the heat source, and low-temperature hydrogen or liquid hydrogen is used as the cold source. When using indirect heat exchange, the hot medium channel 103 and the material jacket 102, as well as the cold medium channel 104 and the material jacket 102, are mutually isolated.

[0030] When both direct heat exchange and indirect heat exchange are used simultaneously, the hot medium channel 103 and the material jacket 102, as well as the cold medium channel 104 and the material jacket 102, are isolated from each other. The first heat source and the first cold source operating in the hot medium channel 103 and the cold medium channel 104 do not contact the metallic hydrogen storage material, thus performing indirect heat exchange. Liquid substances can be used for the first heat source and the first cold source used for indirect heat exchange to improve heat exchange efficiency. Furthermore, while performing indirect heat exchange, a second heat source or a second cold source can be introduced into the corresponding material jacket 102 according to heat exchange requirements to perform direct heat exchange. High-temperature hydrogen can be used as the second heat source, and low-temperature hydrogen or liquid hydrogen can be used as the second cold source. Direct heat exchange between hydrogen or liquid hydrogen and metallic hydrogen storage materials can trigger the metallic hydrogen storage materials to immediately enter a hydrogen absorption or desorption state, completing the instantaneous switching between hydrogen absorption and desorption while exchanging heat. By rapidly introducing a large amount of cold or hot medium into the material rotation mechanism, the metallic hydrogen storage materials can be rapidly cooled or heated, and the switching between hydrogen absorption and desorption states can be completed quickly.

[0031] Figure 12 A top view of a material rotation mechanism that employs both direct heat exchange and indirect heat exchange is shown. Figure 13 and Figure 14 They are shown respectively Figure 12 Cross-sectional views in the CC and BB directions. Figure 15 It shows Figure 13 A sectional view along the AA direction. Figure 15 The rotating frame carrying the metal hydride is not shown in the AA direction cross-sectional view.

[0032] As can be seen from the above figures, the material rotation mechanism employing both direct heat exchange and indirect heat exchange also includes the material jacket 102, hot medium channel 103, cold medium channel 104, first rotating plate 105, second rotating plate 106, and drive device for rotation described earlier, which will not be repeated here. It should be noted that for... Figures 12 to 15The material rotation mechanism, which simultaneously employs direct heat exchange and indirect heat exchange, has the following features: On the high-temperature side of the heat medium channel 103, there is a high-temperature side indirect heat exchange medium inlet 137 at the top and a high-temperature side indirect heat exchange medium outlet 138 at the bottom; a hydrogen absorption inlet 139 is located on the side of the high-temperature side, accompanied by a high-temperature side direct heat exchange hydrogen inlet 140; a high-temperature side direct heat exchange hydrogen outlet 141 is also located on the side of the high-temperature side. The high-temperature side direct heat exchange hydrogen outlet 141 is positioned lower than the positions of the hydrogen absorption inlet 139 and the high-temperature side direct heat exchange hydrogen inlet 140. On the low-temperature side of the cold medium channel 104, there is a low-temperature side indirect heat exchange medium inlet 142 at the top and a low-temperature side indirect heat exchange medium outlet 143 at the bottom. A hydrogen release outlet 144 is located on the side of the low-temperature side, accompanied by a heat exchange circulating hydrogen outlet 145. A heat exchange circulating hydrogen inlet 146 is also located on the side of the low-temperature side. The position of the heat exchange circulation hydrogen inlet 146 is lower than the positions of the hydrogen outlet 144 and the heat exchange circulation hydrogen outlet 145. The high-temperature side direct heat exchange hydrogen inlets and outlets 140 and 141, as well as the heat exchange circulation hydrogen outlets and inlets 145 and 146, are all connected to the corresponding internal hydrogen pipelines 148 within the material rotation mechanism. Hydrogen or liquid hydrogen used for direct heat exchange enters and exits the material rotation mechanism via the internal hydrogen pipelines 148. Filter screens 149 are installed inside the high-temperature side direct heat exchange hydrogen inlets and outlets 140 and 141, as well as the heat exchange circulation hydrogen outlets and inlets 145 and 146, to filter the hydrogen or liquid hydrogen used for direct heat exchange, preventing the introduction of impurities into the material interlayer and thus contaminating the metal hydride. In a material rotation mechanism that simultaneously employs direct heat exchange and indirect heat exchange, a rotary drive fork 147, which is linked to the drive device, is located above the material interlayer, the hot medium channel, and the cold medium channel, driving the first rotating plate 105 and the second rotating plate 106 to rotate.

[0033] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
