Example Embodiment

[0043] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0044] like figure 1 shown, figure 1 A schematic structural diagram of a tower solar thermal power generation system with double-stage heat storage provided by the present invention, the system at least includes a light-to-heat conversion subsystem, a double-stage heat storage subsystem and a power subsystem. Among them, the photothermal conversion subsystem is used for receiving and concentrating solar radiation energy, converting the received solar radiation energy into heat energy, and outputting it to the power subsystem or the dual-stage heat storage subsystem. The dual-stage thermal storage subsystem is used to store the thermal energy input by the photothermal conversion subsystem, and provide thermal energy to the power subsystem w...

Abstract

The invention relates to the technical field of solar energy thermal power generation and discloses a tower-typed solar energy thermal power generation system with two-stage thermal storage. The system at least comprises a photo-thermal conversion subsystem, a two-stage thermal storage subsystem and a power subsystem; wherein, the photo-thermal conversion subsystem is used for receiving and converging solar radiation energy, converting the received solar radiation energy into heat energy, and transmitting the heat energy to the power subsystem or the two-stage thermal storage subsystem; the two-stage thermal storage subsystem is used for storing the heat energy input by the photo-thermal conversion subsystem and providing the heat energy for the power subsystem when the solar radiation energy is not enough; the power subsystem is used for converting the received heat energy into electrical energy and outputting the electrical energy. By adopting the invention, the problem that the steam is difficult to store is solved, and the difficulty that the running of a steam turbine in the previous tower-typed solar energy thermal power generation proposal by taking the steam as heat absorption working substance is influenced by the unstable and discontinuous solar radiation is overcome.

Description

technical field [0001] The invention relates to the technical field of solar thermal power generation, in particular to a tower-type solar thermal power generation system with double-stage heat storage. Background technique [0002] At present, solar thermal power generation technology has been widely used. The system types and system characteristics of commonly used solar thermal power generation technologies are summarized as follows: [0003] 1. Parabolic trough solar thermal power generation system [0004] The parabolic trough solar thermal power generation system is a form of solar thermal power generation that uses a trough parabolic reflector to meet the requirements of concentrating light. The temperature is generally lower than 400 ℃. The system usually consists of a concentrating heat collection device, a heat storage device, a power generation device or / and an auxiliary energy device (such as a boiler), etc. The parabolic trough solar thermal power generation...
