The invention is applicable to the field of solar energy photo-thermal power generation, and provides a feed uniform distribution and stirring device of a solar energy photo-thermal power generation heat accumulation tank, wherein a first pipeline 3 is arranged at one side in a heat accumulation tank 11, a lower end opening of the first pipeline is arranged under a lower liquid level line 13, and an upper end opening of the first pipeline is arranged outside the heat accumulation tank 11; the upper end of the first pipeline 3 is provided with a pump set 1 and a first valve 2 used for controlling whether the first pipeline is communicated with the outside or not; a second pipeline 5 is communicated with the first pipeline 3 and a third pipeline 6; a second valve 4 used for controlling whether the first pipeline 3 and the third pipeline 6 are communicated with each other or not is arranged in the middle of the second pipeline 5; the third pipeline 6 is arranged in the direction of a central axis of the heat accumulation tank 11, and the upper end of the third pipeline is provided with a third valve 7 used for controlling whether the third pipeline is communicated with the outside or not. According to the feed uniform distribution and stirring device, stirring is realized by the plurality of pipelines; the feed uniform distribution and stirring device is simple in structure, economical and efficient, and effectively solves the problems that a heat storage medium of a solar energy photo-thermal power generation heat accumulation system has the phenomenon of temperature stratification and is not uniform in heat accumulation temperature distribution, and the multi-element medium has composition segregation, so that the stability and the safety of system operation are greatly improved.
Description
technical field [0001] The invention belongs to the technical field of solar thermal power generation, and in particular relates to a material uniform distribution and stirring device for a heat storage tank of solar thermal power generation. Background technique [0002] Compared with photovoltaic power generation and wind power generation, solar thermal power generation technology has the characteristics of grid friendliness and easier acceptance by the grid, and will be one of the most promising power generation methods in renewable energy power generation. [0003] At present, in order to solve the problem of energy storage in solar thermal power generation, it is necessary to install a heat storage device. When the heat collecting field is working normally, a part of the heat energy is stored in the energy storage device. When the heat collecting field cannot provide When heat is generated, the energy storage device releases heat, which continues to supply the steam tur...
