Abstract

The invention discloses a heat and electricity dual-purpose system capable of combining chemical heat storage with seawater power generation. Resources are fully used for providing convenience for users near lakes and seas or islands; the solar thermal energy is used for enabling salt hydrates to generate the desorption-absorption reaction; and the energy change in the process is used for generating electricity or supplying heat. The heat and electricity dual-purpose system capable of combining chemical heat storage with seawater power generation fully exerts the energy storage and energy release effects of the salt hydrates; through utilization of such resources as solar energy and seawater, the whole set of system can be continuously operated; the heat supply and the power generation canbe performed according to different demands under different conditions, so that the flexibility is higher; in addition, the heat and electricity dual-purpose system capable of combining chemical heatstorage with seawater power generation is low in energy loss and high in heat efficiency, can solve the power supply and heat supply problems of the users or the islands to a certain extent by usingthe seaward or lake approaching advantages; the whole process is safe and environment-friendly; and the development prospect is excellent.

Description

technical field [0001] The invention relates to the technical field of chemical energy storage and seawater power generation, in particular to a thermoelectric dual-purpose system combining chemical heat storage and seawater power generation. 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 pay more and more attention to energy conservation and emission reduction. In order to use energy more rationally and efficiently, energy needs to be stored. Compared with sensible heat storage and latent heat storage, chemical heat storage has higher energy density and negligible heat loss, which can be used across seasons. Compared with other types of chemical heat storage methods, the decomposition reaction of hydrated salt has relatively lower operating requirements and costs, and ...
