[0025] Molten salt heater 2 raises the temperature of the molten salt. The molten salt remains liquid at high temperatures, effectively storing thermal energy. The molten salt enters the storage tank through molten salt inlet pipe 7. Inside the tank, the molten salt's temperature rises after heating, storing thermal energy. The molten salt circulates within the tank, ensuring uniform heat distribution. When the power grid requires additional electricity, the molten salt is pumped to molten salt outlet pipe 5, which is connected to a molten salt cooler. In the cooler, the thermal energy of the molten salt is transferred to the working fluid, causing it to evaporate and generate steam. The generated steam drives a turbine generator, converting it into electrical energy for power grid use.

[0026] like Figure 1 and Figure 2 As shown, a chassis 3 is installed at the lower end of the molten salt tank 1. The diameter of the chassis 3 is larger than the diameter of the molten salt tank 1. Multiple molten salt heaters 2 are installed inside the molten salt tank 1, extending into the interior of the molten salt tank 1. A liquid distribution ring pipe 15 is installed at the bottom of the molten salt tank 1. The liquid distribution ring pipe 15 is connected to the salt inlet pipe 12. The liquid distribution ring pipe 15 has a ring structure design, which makes the molten salt evenly distributed inside the molten salt tank 1. The molten salt pump motor 9 drives the molten salt pump body 14 to work. The molten salt pump body 14 discharges the molten salt from the molten salt outlet pipe 5. The sleeve 6 is wrapped around the outer wall of the molten salt outlet pipe 5. The water inlet 8 adds cooling water into the interior of the sleeve 6. The spiral pipe 11 inside the sleeve 6 is used for the flow of cooling water. The water outlet 4 discharges the cooling water.

[0027] A sleeve 6 is fitted onto the outside of the molten salt outlet pipe 5. Cooling water is added to the inside of the sleeve 6 through the water inlet 8 at the upper end of the sleeve 6. The cooling water flows through the spiral tube 11 inside the sleeve 6 and makes full contact with the molten salt outlet pipe 5. This can reduce the temperature of the molten salt outlet pipe 5, prevent overheating, and protect the interface from damage.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
