[0019] The beneficial effects of the present invention are:

[0020] 1. The interior of the heat exchange component is used to store molten salt, and the heat exchange component is heated to store energy in the molten salt. A water source is introduced through one end of the energy storage component. The water source is heated by the molten salt and becomes steam, and the steam is stored in the energy storage component.

[0036] The embodiment of the present invention provides a heat pipe molten salt energy storage and supply device, including a heat preservation tube 1, a heat exchange component 2 and an energy storage component 3; illustratively, as Figure 1 and Figure 2 shown.

[0038] Specifically, the interior of the heat exchange component 2 is used to store molten salt, and the heat exchange component 2 is heated to store energy in the molten salt. When the thermal energy stored in the molten salt is needed, a water source is introduced through one end of the energy storage component 3.

The steam collected in the energy storage component 3 is used for steam power generation to achieve energy supply.

[0039] The heat exchange assembly 2 includes a heat exchange mechanism 21 and a medium input mechanism 22; illustratively, Figure 3 shown.

[0040] The heat exchange mechanism 21 is arranged in a spiral shape, and one end of the heat exchange mechanism 21 is connected to a medium input mechanism 22 . The medium input mechanism 22 is embedded and installed on the outer wall of the heat preservation cylinder 1 .

[0043] The medium input mechanism 22 includes a linkage disk 221 and a second solenoid valve 226; for example, Figure 6 shown.

[0044] The outer wall of the linkage disk 221 is embedded with an air pump 222, a water source connector 223 and a molten salt feed connector 224, and the air pump 222, the water source connector 223 and the molten salt feed connector 224 are arranged in a circular array with the central axis of the linkage disk 221 as the center. The output end of the servo motor 225 is transmission-connected at the center of the central axis of the linkage disk 221, and the side of the servo motor 225 away from the output end is embedded in the outer wall of the insulation cylinder 1, and the second solenoid valve 226 is embedded in the outer wall of the insulation cylinder 1, and one end of the second solenoid valve 226 is respectively connected to the outer wall of the insulation cylinder 1. The interfaces of the air pump 222, the water source connector 223 and the molten salt feeding connector 224 are interconnected. A particle suction pump is also provided on the second solenoid valve 226. The other end of the second solenoid valve 226 is connected to a medium input pipe 227, and the port of the medium input pipe 227 is connected to the other end of the spiral heat exchange tube 211. The outer wall of the medium input pipe 227 is fixedly connected to a cylinder bracket 228, and a pneumatic telescopic rod 229 is fixedly connected to the cylinder bracket 228. The output end of the pneumatic telescopic rod 229 is transmission-connected to the top of the linkage plate 216.

[0045] The energy storage assembly 3 includes an energy storage box 31; for example, Figure 7 shown.

[0046] A plurality of steam output pipes 32 are embedded in one side wall of the energy storage box 31, and the plurality of steam output pipes 32 are interconnected with the steam recovery hole 212, and a one-way valve is provided inside the plurality of steam output pipes 32. A steam recovery pipe 33 is connected to the outer wall of the energy storage box 31 and the side away from the plurality of steam output pipes 32, and one end of the steam recovery pipe 33 extends to the outside of the insulation cylinder 1.

[0047] Specifically, the molten salt feeding connector 224 connects the molten salt particles, and uses the particle suction pump to work continuously and the second solenoid valve 226 to open, so that the molten salt particles enter the spiral heat exchange tube 211 in sequence, and the output end of the pneumatic telescopic rod 229 drives the linkage piece 216 to move upward, so that the electric heating tube 215 moves from the middle position of the inner cavity of the spiral heat exchange tube 211 to the top position of the inner cavity, and the space for feeding or changing materials is reserved for the molten salt particles to be transported to the spiral heat exchange tube 211, so that the molten salt particles can be quickly filled into the spiral heat exchange tube 211;

[0048] During the continuous operation of the electric heating tube 215, the electric heating tube 215 generates heat in the spiral heat exchange tube 211, so that the spiral heat exchange tube 211 heats the molten salt inside and stores energy. When the heat energy stored in the molten salt is needed, the output end of the servo motor 225 is used to drive the linkage disk 221 to rotate, so that the water source connector 223 is connected to the water pipe, and the water source is transported to the spiral heat exchange tube 211. The water source is heated by the molten salt and becomes steam. The steam is transferred to the steam output pipe 32 through a plurality of steam recovery holes 212 and is stored in the energy storage box 31. Under the dual insulation effect of the energy storage box 31 and the insulation tube 1, the stored steam can fully utilize the heat stored in the molten salt, thereby improving the working efficiency of the energy storage and supply device while reducing heat loss.

[0049] The first solenoid valve 214 is opened, and the servo motor 225 is used to rotate the linkage disk 221 to rotate the air pump 222 to a state of being connected with the second solenoid valve 226. Then, the air pump 222 and the second solenoid valve 226 are started to input gas into the spiral heat exchange tube 211, so that the molten salt particles agglomerated in the spiral heat exchange tube 211 are discharged outwardly through the first solenoid valve 214, which is convenient for regular replacement of molten salt particles.

[0050] When the output end of the pneumatic telescopic rod 229 drives the linkage piece 216 to move downward, the limiting pin 217 contacts the top of the spiral heat exchange tube 211, thereby limiting the continuous falling of the electric heating tube 215, so that the electric heating tube 215 is located in the center of the spiral heat exchange tube 211, and the molten salt particles stored in the spiral heat exchange tube 211 can be evenly heated.

[0051] A heat pipe molten salt energy storage and supply device proposed in an embodiment of the present invention has the following working principle:

[0052] The molten salt particles are connected through the molten salt feeding connector 224, and the particle suction pump is continuously working and the second solenoid valve 226 is opened, so that the molten salt particles enter the spiral heat exchange tube 211 in sequence, and the output end of the pneumatic telescopic rod 229 drives the linkage piece 216 to move upward, so that the electric heating tube 215 moves from the middle position of the inner cavity of the spiral heat exchange tube 211 to the top position of the inner cavity, and the space for feeding or changing the material is reserved for the molten salt particles to be transported to the spiral heat exchange tube 211, so that the molten salt particles can be quickly filled into the spiral heat exchange tube 211;

[0053] During the continuous operation of the electric heating tube 215, the electric heating tube 215 generates heat in the spiral heat exchange tube 211, so that the spiral heat exchange tube 211 heats the molten salt inside and stores energy. When the heat energy stored in the molten salt is needed, the output end of the servo motor 225 is used to drive the linkage disk 221 to rotate, so that the water source connector 223 is connected to the water pipe, and the water source is transported to the spiral heat exchange tube 211. The water source is heated by the molten salt and becomes steam. The steam is transferred to the steam output pipe 32 through a plurality of steam recovery holes 212 and is stored in the energy storage box 31. Under the dual insulation effect of the energy storage box 31 and the insulation tube 1, the stored steam can fully utilize the heat stored in the molten salt, thereby improving the working efficiency of the energy storage and supply device while reducing heat loss.

[0054] Since the molten salt undergoes a phase transition from solid to liquid during the heat storage process, it will gradually decay during this process, resulting in a decrease in its phase change heat, affecting the heat storage efficiency. During the heat release process, the molten salt is easy to agglomerate and form large voids, which will reduce the heat storage density and thermal conductivity, affecting the overall performance of the system. The molten salt needs to be replaced regularly. By opening the first solenoid valve 214, the servo motor 225 is used to rotate the linkage disk 221, and the air pump 222 is rotated to a state connected with the second solenoid valve 226. Then, the air pump 222 and the second solenoid valve 226 are started, and the gas is input into the spiral heat exchange tube 211, so that the agglomerated molten salt particles in the spiral heat exchange tube 211 are discharged outwardly by the first solenoid valve 214, which is convenient for the regular replacement of the molten salt particles.

[0055] In the process of driving the linkage plate 216 downward through the output end of the pneumatic telescopic rod 229, the limiting pin 217 is used to contact the top of the spiral heat exchange tube 211, so as to limit the continuous falling of the electric heating tube 215, so that the electric heating tube 215 is located in the center of the spiral heat exchange tube 211, and the molten salt particles stored in the spiral heat exchange tube 211 can be evenly heated.

[0056] Based on the above-mentioned heat pipe molten salt energy storage and supply device, an embodiment of the present invention further provides a method for using the heat pipe molten salt energy storage and supply device, comprising the following steps:

[0057] The interior of the heat exchange component is used to store molten salt, and the heat exchange component is heated to store energy in the molten salt;

[0058] A water source is introduced through one end of the energy storage component, the water source is heated by the molten salt and becomes steam, and the steam is stored in the energy storage component;

[0059] The steam collected in the energy storage component is used for steam power generation to achieve energy supply.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
