Solar photo-thermal power station and heat absorption system thereof

The invention discloses a solar photo-thermal power station and a heat absorption system of the solar photo-thermal power station, and belongs to the field of solar photo-thermal power stations. The heat absorption system comprises a heat absorption working medium inlet pipeline, a working medium buffering tank and a heat absorption working medium outlet pipeline, heat absorption working media enter the working medium buffering tank through the heat absorption working medium inlet pipeline, the working medium buffering tank is provided with a working medium inlet serving as a focusing light spot incidence opening, focusing light spots do not pass through a heated tube and directly illuminate the working media inside the working medium buffering tank, and after absorbing heat, the working media come out of the working medium buffering tank through the heat absorption working medium outlet pipeline. The heat absorption system is suitable for the photo-thermal power station and is arranged on the ground, the mirror field focusing light spots directly illuminate the heat absorption working media, and the problems that a heat absorber adopted for an existing photo-thermal power station is arranged in a high-altitude mode, so that installing, operating and maintaining are difficult, a tube panel is heated unevenly, the manufacturing cost is high, and power consumption of a factory is high are directly solved.
