Abstract
The utility model discloses an off-peak electricity high-temperature heat storage steam power generating system. The off-peak electricity high-temperature heat storage steam power generating system includes a thermal storage box. High-temperature thermal-storage bricks or phase-change fuse salt balls are arranged in an inner cavity of the thermal storage box. Side walls of the thermal storage box are provided with an inlet and an outlet. The inlet and the outlet are connected with a heat-conducting medium heating and conveying pipe separately. The heat-conducting medium heating and conveying pipe separately is connected with an electric boiler and a high-temperature circulating pump. High-temperature heat-conducting oil or fuse salt can be heated in the electric boiler and then conveyed to the thermal storage box through the conducting medium heating and conveying pipe. The inlet and the outlet in the side walls of the thermal storage box are also connected with a plate-type heat exchange provided with a cold water inlet and a hot water outlet. Through heat conduction performed by the high-temperature heat-conducting oil or the fuse salt, high-temperature thermal energy is stored in the high-temperature thermal storage bricks or the phase-change fuse salt balls and the high temperature realized through thermal storage can be higher than 300 DEG C. The thermal energy can be released in peak periods of a power grid in the day and high temperature steam produced through heat exchange performed by the heat exchanger can be used for utilization in production processes or for power generation of a steam turbine.
