The invention relates to a heat exchange equipment based on a fluidized bed and a phase change material, the equipment specifically comprises a fluidized bed, a first cyclone separator, a high temperature solid-liquid separator, a heat collecting field, a liquid phase change material storage tank, a first Two cyclones, heat exchangers, solid phase change material storage tanks. Compared with the more commonly used sensible heat heat storage technology, the device of the present invention has a higher energy density because it adopts the phase change material heat storage technology, because it has higher heat capacity and better energy storage performance, so The required device occupies a smaller area than the sensible heat energy storage technology, and can achieve heat absorption and heat release at the same time, and in the process of heat absorption and release, the material temperature changes are small, the device structure is simple, and the accident rate is low. |
