HEAT STORAGE SYSTEM BASED ON MOLTEN SALT HEAT TRANSFER, AND OPERATION METHOD

WIPO Patent Application WO/2023/246021

A1

Provided are a heat storage system based on molten salt heat transfer, and an operation method. The heat storage system comprises a solid heat storage module (1), lead-out pipes (2), a molten salt tank (4) containing molten salt (15) at a certain liquid level, a molten salt pump (5), a first valve (6), a second valve (7), a third valve (8), a heat charging device (9), a heat discharging device (10), a first valve group (11), a second valve group (12), a housing (13), and a fourth valve (14). The solid heat storage module (1) is arranged in the housing (13) and comprises a plurality of sub-units arranged side by side, and the upper part and the lower part of each sub-unit are respectively provided with valves, so that each sub-unit can independently perform heat charging and discharging processes. The system is used for realizing opposite flowing directions of molten salt (15) in a solid heat storage module (1) in heat charging and discharging processes, thereby improving a heat exchange effect.
