Molten salt system

The utility model discloses a molten salt system, which relates to the technical field of molten salt energy storage and comprises an energy storage device, the energy storage device comprises a low-temperature molten salt storage mechanism, a high-temperature molten salt storage mechanism, a heating mechanism and a heat release mechanism, and the low-temperature molten salt storage mechanism and the high-temperature molten salt storage mechanism are both used for storing nitrate molten salt. A salt outlet of the low-temperature fused salt storage mechanism is connected with a salt inlet of the high-temperature fused salt storage mechanism through a first pipeline, a salt inlet of the low-temperature fused salt storage mechanism is connected with a salt outlet of the high-temperature fused salt storage mechanism through a second pipeline, a heating mechanism is arranged on the first pipeline, and a heat release mechanism is arranged on the second pipeline. An exhaust port is further formed in the energy stora
