Description

Technical Field

[0001] The utility model relates to the technical field of steam heat exchange, in particular to a steam energy heat exchange water storage system. Background Art

[0002] With the rapid economic growth, the production volume of enterprises is constantly increasing, and the energy consumption is also increasing. At this stage, the contradiction between the supply and demand of electric energy is becoming increasingly prominent, especially in urban power supply. The power supply is insufficient during peak hours, and the difference between peak and valley power consumption is increasing. Therefore, the state has implemented peak-valley electricity price policies in some provinces and cities to ease the pressure of power supply during peak hours and encourage people to use electricity during valley hours.

[0003] The existing invention patent with publication number CN117606002A and its name is a steam-heated molten salt energy storage system, which includes a boiler, a main steam molten salt heat exchanger, a hot section molten salt heat exchanger, a cold reheat steam unit, a reheat steam branch pipe, a cold tank, a hot tank, a low-pressure cylinder, a medium-pressure cylinder, a high-pressure cylinder and an intelligent diagnostic system; the main steam in the boiler enters the main steam molten salt heat exchanger to heat the molten salt, and the main steam is connected in parallel with a first preheating pipe, and the air inlet of the first preheating pipe is connected to the air outlet of the main steam, and the air outlet of the first preheating pipe is connected to the air inlet of the main steam molten salt heat exchanger; the other way enters the high-pressure cylinder to do work.

[0004] When this system is in use, the steam and molten salt are heat exchanged and stored, and the molten salt is reused after absorbing heat. The actual temperature of the steam drops after exchanging heat with the molten salt. Since the steam in this temperature range cannot heat the molten salt to the highest temperature, it will re-enter the boiler for heating through some steam condensing devices, resulting in heat loss of this section of saturated steam.
