Embodiment Construction

[0032] plan 1

[0033]The trough heat storage and cascade evaporative heat generation are connected in series with the trough concentrators 1 to form a concentrating array like the existing solar thermal power station. Taking the "European trough" as an example, the concentrating array generally consists of 4 One or six independently driven concentrating single rows form a cycle, and its inlet and outlet are connected to the main pipeline of heat transfer oil. The difference in this scheme is that the solar receivers are connected in series or in parallel to form a concentrating array, and the solar energy of the concentrating array The outlet of the receiver 3 is connected to the inlet of the evaporator 20, the outlet of the evaporator 3 leads to the heat storage pool 21 or the heat storage battery 22, the outlet of the heat storage pool 21 or the heat storage battery 22 is connected to the high temperature power pump 23, and the outlet of the high temperature power pump 23 is...

Abstract

The invention belongs to the technical field of solar thermal power generation, provides an independent cyclic heat storage and electric power storage and cascaded heat exchange and evaporation technology and relates to a large-scale solar thermal power station formed by being combined with trough type solar concentrators, tower type solar concentrators and the like with molten salt or sulfur and quick sand as heat storage and heat transfer fluid. According to the solar thermal power station, the brand new cascaded evaporation technology is adopted while the integrated design of heat storage and electric power storage is considered, standardization and mass production of manufacturing of solar power generation equipment are promoted, and the investment cost of the power station can be lowered; the power supply capacity of the solar thermal power station is improved, the operating cost of the solar thermal power station is lowered, the power generation hours are increased substantially, and the capability of the solar thermal power station competing with fossil energy power generation is improved.

Description

technical field [0001] The invention adopts independent cycle heat storage and electricity storage and cascade heat exchange and evaporation technology, uses molten salt or sulfur and quicksand as heat storage and heat transfer fluid, and combines with trough type, tower type and other solar concentrators to form a large-scale solar thermal Power station; the device adopts a new cascade evaporation technology while taking into account the integrated design of heat storage and power storage, which is not only beneficial to the standardization and scale of solar power generation equipment manufacturing, but also conducive to reducing the investment cost of the power station, improving its own power supply capacity and reducing operating costs. cost, significantly increase the number of hours of power generation, and improve the ability to compete with fossil energy power generation. The device belongs to the technical field of solar thermal power generation. Background techniq...
