Problems solved by technology

Its disadvantage is the same as most of the patents mentioned above, that is, it does not use the latent heat of refrigerant condensation in the energy storage stage but directly discharges the heat to the outside; although different temperature zones are formed, the reaction rates of various reaction salts at different temperatures The difference is also large, and it is difficult to maintain a consistent pressure, so the problem of uneven force on the reactor cannot be completely avoided; in addition, the evaporation heat of the refrigerant in the energy release stage depends on the external temperature, which has also become an unstable factor

Abstract

The invention discloses a heat and electricity dual-purpose system based on hydrous salt chemical heat storage and a using method thereof. The system comprises a heat storage system, a first power generation system and a heat supply system. The heat storage system comprises a solar air heat collector, a reactor, a first heat exchanger, a gas-liquid separator, a heat preserving water tank and a flash chamber. The first power generation system comprises a turbine motor, a generator and a condenser. The heat supply system comprises a heat exchange coiler arranged in the reactor, a second heat exchanger and a water storing tank. According to the dual-purpose system, latent heat of steam condensing can be fully utilized through the first power generation system, the benefit is increased, and by selecting a suitable energy storing material and conforming to the actual operation situation, feasibility of work is improved. In addition, power generation and heat supply are brought into the whole system and used in parallel, and the system can be used for supplying electricity or heat according to needs during different hours.

Description

technical field [0001] The invention relates to the technical field of thermochemical energy storage, in particular to a thermoelectric dual-purpose system based on hydrated salt chemical heat storage and a method for using the same. Background technique [0002] Energy is the material basis of human activities, and the continuous development and utilization of energy has promoted the development of human civilization. As the energy crisis becomes more and more serious, human beings gradually turn their attention to new energy sources. Solar energy, geothermal energy, ocean energy, wind energy, nuclear energy and other new energy sources have also been developed relatively rapidly. However, the utilization of new energy sources also has its own limitations, such as the instability of wind energy and the safety of nuclear energy. solved problem. In order to use energy more reasonably and efficiently, it is necessary to store energy, which is also the focus of scholars' atte...
