Photo-thermal power generation system

Abstract

The invention provides a photo-thermal power generation system, and belongs to the technical field of solar power generation. The photo-thermal power generation system comprises a power generation device, a heat storage device, an output device, a steam generation device and a circulation device, and the circulation device can be sequentially connected in series with the power generation device, the heat storage device and the output device to form a closed circulating first circulating path; the circulation device can also be sequentially connected with the heat storage device and the output device in series so as to form a closed circulating second circulating path; the power generation device can convert light energy into heat energy; in the first circulation path, the heat storage device can absorb part of the heat energy generated by the power generation device, and the output device can absorb part of the heat energy generated by the power generation device; in the second circulation path, the output device can absorb the heat energy in the heat storage device; and the output device can also exchange heat with the steam generation device. The photo-thermal power generation system solves the problems that a photovoltaic power generation system in the prior art is influenced by illumination and cannot continuously generate power, and continuous operation of electric equipment is influenced.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and more specifically relates to a photothermal power generation system. Background technique [0002] Latent heat energy storage is also called phase change energy storage. Latent heat energy storage technology uses latent heat energy storage materials to release and absorb heat energy in the process of phase change (ie solidification, melting, sublimation, sublimation, condensation or gasification) to realize energy. store. Latent heat energy storage materials are divided into low-temperature phase change materials (ice, paraffin, etc.) and high-temperature phase change materials (metals, alloys, high-temperature molten salts and mixed salts, etc.). The process is approximately constant temperature. [0003] At present, the most commonly used power generation devices in plain areas or low-altitude areas are photovoltaic power generation systems. Photovoltaic power generation us...
