Embodiment 1
[0026] Such as figure 1 As shown, a conceptual diagram of calcium cycle cascade thermochemical energy storage, including primary energy storage (CaCO 3 energy storage) and secondary energy storage (Ca(OH) 2 Energy storage), energy storage is carried out through the interaction conversion between thermal energy generated by solar energy and chemical energy, primary energy storage: when there is sufficient sunlight during the day, CaCO 3 The particles undergo a thermal decomposition reaction through solar heat exchange and decompose into CaO and CO 2 Carry out primary energy storage; secondary energy storage: upper level CO 2 The residual heat can be used to exchange heat with water vapor, so that Ca(OH) 2 The particles undergo a thermal decomposition reaction and decompose into CaO and H 2 O for secondary energy storage; when energy is needed, CaCO 3 The CaO produced by particle decomposition will combine with H 2 O undergoes a reverse chemical reaction to release heat en...
