Description
Technical Field

Background
With the development of society, the energy consumption demand of people is increasing, and the problems of energy shortage and environmental pollution are becoming more severe. In order to realize "carbon peak reaching" and "carbon neutralization", vigorous development and utilization of renewable energy sources such as solar energy become important approaches. However, because solar energy has the characteristics of intermittency, fluctuation and the like, the development of a heat storage technology is particularly important for ensuring efficient and continuous energy supply. The heat storage technology mainly comprises three technologies of sensible heat storage, latent heat storage and thermochemical heat storage. The thermochemical heat storage has many advantages compared with sensible heat storage and latent heat storage, such as higher heat storage density, long-term storage of the heat storage material without heat preservation treatment, and trans-regional and trans-seasonal energy storage and utilization.
The patent CN110822868A provides a solar drying system integrating heat absorption, heat storage and water collection, which utilizes the heat provided by solar energy to dry the material, and stores the solar energy through a hydrate chemical heat storage device, so that the material can be continuously dried when the illumination is insufficient. However, when the illumination is insufficient, namely in the heat release stage, air in the environment is introduced into the heat storage module, and hydration heat release is carried out by utilizing moisture in the air and the heat storage material, so that the method is theoretically feasible, but in most cases, the moisture content of the air is limited, so that the heat release rate is greatly reduced, and the aim of drying the material cannot be achieved. The invention patent CN103256792B proposes a combined solar thermochemical cascade utilization device, in which multiple heat storage materials with different equilibrium temperatures are arranged in series, so that cascade storage of heat energy can be realized during the heat storage process, and the solar energy can be stored even when the illumination is not strong. The device has the defects that gas generated by the reaction is discharged out of the reaction device under the condition of no external driving force, and the problems can cause that products generated by the reaction cannot be taken away in time and are accumulated in the reactor to block the reaction, so that the heat storage efficiency is not high.
