Abstract

Disclosed is a fused salt energy storage heating heat-exchange system. An integrated device with a large-capacity and good thermal insulation fused salt tank, an electric heating tube for heating in a fused salt liquid and a radiation heat exchange tube which is mounted in the fused salt liquid and used for heat exchange is applied, thereby, the complicated process of fused salt energy storage and heat exchange application is simplified, and a technology of fused salt energy storage is easy to implement and extremely low in costs; direct heating is performed in the fused salt liquid so that the heating efficiency is high, radiant heat exchange is performed in the fused salt liquid so that the heat exchange efficiency is high, energy is controllable, safety and reliability are achieved, and off-peak electric energy is stored as required; the energy is used for heat supply of residential quarters in winter, the ultra-large fused salt tank is used, and heat energy is stored by the off-peak electric energy at night; high-pressure steam is generated through the heat exchange tube to push a steam turbine to generate electricity during on-peak power utilization, and insufficient power can be supplemented; compared with other energy storing methods, the method of electricity generation by the fused salt energy storage has the advantages that the investment is small, the method can rapidly take effect, the price of energy storing media is low, the source is wide, materials are easy to obtain, and the heat conversion efficiency is high.

Description

technical field [0001] The invention relates to the technical field of molten salt energy storage heating and heat exchange, in particular to a molten salt energy storage heating heat exchange system. Background technique [0002] At present, the gap between peak and valley power supply is large, the power supply is tight during peak power consumption, and cannot meet the demand, and the proportion of power usage in the low valley at night is very small, and the large power energy cannot be effectively used. Contradictory, it is very necessary, power low valley energy storage is widely used at present; 1. Use the water drop to drive the water turbine to generate electricity to make up for the shortage of power supply during the peak power consumption. However, pumped storage is limited by geographical conditions, the investment is huge, and the conversion efficiency is less than 70%. Molten salt heat storage is a new emerging technology. At present, the energy storage techn...
