Description

technical field [0001] The invention relates to the technical field of solar photothermal power generation energy storage, in particular to a method for treating the inner surface of a solar photothermal power generation heat storage device. Background technique [0002] The heat storage medium in the solar thermal power generation energy storage system is mostly a high temperature medium, and the required stress of the structural material of the heat storage device decreases with the increase of the medium temperature, which seriously affects the safety of the heat storage device and the entire solar thermal power generation system; [0003] Traditional solutions mostly use the method of thickening the structural thickness of the heat storage device for strength compensation. This method not only increases the cost of materials, but also increases the difficulty of processing and manufacturing. Contents of the invention [0004] The technical problem to be solved by the p...
