Abstract
This invention provides a storage tank for ultra-high temperature molten salt energy storage, belonging to the field of molten salt energy storage technology. It includes a double-shell molten salt storage tank with a heating chamber between the shells. The heating chamber contains an electric heating tube. It also includes a stirring and heating steam section for optimized heating. The stirring and heating steam section includes a stirring tube and a U-shaped hot steam pipe connected within the double-shell molten salt storage tank. Both the stirring tube and the U-shaped hot steam pipe have several interconnected branch pipes evenly spaced along their bodies. A composite insulation layer is provided on the outer wall of the double-shell molten salt storage tank. This invention achieves dual heating through the combined action of the stirring and heating steam section and the electric heating tube within the heating chamber, thereby improving the heating efficiency of molten salt energy storage. Mechanical stirring and branching keep the molten salt in a flowing state, ensuring uniform heating during flow and preventing localized solidification and temperature stratification during high-temperature molten salt energy storage.
