Heat-storage device for heat-storage electric boiler heat-supply system

The utility model provides a regenerative device used in a regenerative electric boiler heat supply system, which comprises a regenerative pot body, which is a pressure container filled with water; wherein, an inlet pipe and an outlet pipe for high temperature hot water are arranged on the upper part of the regenerative pot body, an inlet pipe and an outlet pipe for lower-temperature hot water are arranged on the lower part of the regenerative pot body, a mechanism for stabilizing the pressure of the pot body is communicated with the inlet pipe and outlet pipe of the pot body. The utility model has a large temperature difference of heat accumulation, a rather high heat accumulation quantity per unit volume and hot water supply; therefore, the size of the regenerative pot body is reduced, the problems in the equipment layout of the heat supply system are completely solved, thus playing a positive role in optimizing the heat supply system and lessening the investment in the system. Moreover, the pressure stabilizing mechanism is communicated with the pot body through the inlet pipe and the outlet pipe for low temperature hot water, the utility model has the advantages of optimal structure, simple pipeline and ability to avoid high temperature hot water from entering and vaporizing at the pressure stabilizing section.
