Abstract

The invention discloses a photo-thermal system. The photo-thermal system comprises a photo-thermal collector and a solid heat storage device; wherein the solid heat storage device comprises a solid heat storage base body and heat exchange pipelines, and the heat exchange pipelines are arranged in the solid heat storage base body, and is used for exchanging heat with the solid heat storage base body; and heat storage inlets of the heat exchange pipelines communicate with steam outlets of the photo-thermal collector, heat storage outlets of the heat exchange pipelines communicate with water return inlets of the photo-thermal collector, so that the photo-thermal collector and the solid heat storage device form a heat energy storage loop. The embodiment of the invention further discloses a photo-thermal power station. According to the scheme, the problems that the power generation efficiency is low, device investment cost is high and the safety coefficient is low due to the fact that heatenergy storage of an existing photo-thermal power generation system by utilizing heat conduction oil or molten salt can be solved.

Description

technical field [0001] The present application relates to the technical field of solar energy utilization, in particular to a photothermal system and a photothermal power station. Background technique [0002] Solar energy has been widely used in many fields, such as the field of optoelectronics, due to its advantages such as abundant resources, no pollution, and low threshold for utilization technology. Using the heat energy generated by sunlight to generate electricity is a rapidly developing technology, and a photothermal power station is a place where the heat energy generated by sunlight is used to complete power generation. In the process of power generation, the heat energy generated by sunlight will turn the water into steam that drives the steam turbine, and then the steam drives the steam turbine generator set to generate electricity. [0003] Although solar energy is an ideal clean energy source, the acquisition of solar energy is time-sensitive. During the day, ...
