The embodiment of the invention provides a solid heat storage system which comprises a cavity defined by a heat preservation wall, and the cavity is filled with protective gas. The solid heat storage system also comprises a heat accumulator, a heat exchanger and a high-temperature fan which are arranged in the cavity, an airflow channel and a heating body are arranged in the heat accumulator, the first heat exchange side of the heat exchanger is used for being connected with external heat utilization equipment, and the high-temperature fan is used for driving the protective gas to circularly flow in the cavity; and the protective gas sequentially passes through an air outlet of the high-temperature fan, the airflow channel in the heat accumulator and the second heat exchange side of the heat exchanger and then flows back to the air inlet of the high-temperature fan. According to the solid heat storage system, the protective gas circularly flows in the cavity of the heat storage system for heat exchange, oxidation corrosion of parts in contact with the gas in the heat storage system can be effectively avoided, an inert protection effect is provided for the system, the working performance of the system is improved, and the service life of the system is prolonged.
Description
technical field [0001] The invention relates to the technical field of solid electric heat storage equipment, in particular to a solid heat storage system. Background technique [0002] Solid heat storage is a heat storage method that converts electrical energy into heat energy and stores it in solid heat storage materials by using low-cost electricity time periods, and releases heat through necessary heat extraction means when heat needs to be provided. The advantages of solid electric heat storage include: high heat storage temperature, small footprint, fast heat storage and release efficiency, stable performance, etc., and can be widely used in areas such as district heating, power plant peak regulation, and industrial production heat. [0003] However, the heat storage body of the solid heat storage system is in direct contact with the circulating air. At the same time, due to the poor sealing performance of the circulation system, corrosive substances such as water vapo...
