Problems solved by technology

However, the molten salt system also has the characteristics of complex pipelines and high freezing point. Therefore, the molten salt system has strict requirements on pipeline preheating, equipment insulation, operation and maintenance, etc., which limits the development of solar molten salt systems to a certain extent.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the multi-tower and geese-arranged solar heat storage power generation system of the present invention includes a heat absorber 1, a heliostat field 2, a steam generating device 3, a fan or a compressor 4, a steam power system 5, a water pump 6, and a generator 7, etc., among which the heliostat field 2 and the heat sink 1 will contain multiples according to different capacity requirements.

[0025] The normal work flow of the present invention comprises as follows:

[0026] The heat absorber 1 and the heliostat field 2 form a heat collection unit, and the heat absorber 1 receives the sunlight reflected by the heliostat field 2, and is absorbed and transformed by the heat-absorbing materials (such as graphite, metal, composite materials, etc.) The heat energy is converted into heat energy, and then transferre...

Abstract

The invention provides a multi-tower wild-goose-queue-type arrayed solar heat storage power generation system which comprises heat absorbers (1), heliostat fields (2), a steam generating device (3), a fan or a compressor (4), a steam power system (5), a water pump (6), a generator (7) and the like, wherein the number of the heliostat fields (2) and the number of the heat absorbers (1) can be multiple according to different capacity requirements. Compared with a solar heat use system with fused salt as a working medium, the multi-tower wild-goose-queue-type arrayed solar heat storage power generation system is simple, integrates heat absorption and heat storage, is rapid and convenient to start and stop, meanwhile, eliminates a large quantity of energy necessarily consumed by the fused salt system in operation maintenance such as electricity preheating and heat reservation before the fused salt system is started and eliminates fused salt solidification risks, so that initial cost and operating cost of the solar heat storage power generation system can be reduced. The multi-tower wild-goose-queue-type arrayed solar heat storage power generation system is beneficial to application and popularization of the solar heat power generating technology.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a multi-tower and geese-arranged solar heat storage power generation system. Background technique [0002] Solar high-temperature thermal power generation technology is an important direction for large-scale utilization of solar energy, and it has far-reaching significance for human beings to solve problems such as fossil energy crisis and air pollution. Due to the advantages of high parameters and large capacity of solar tower focused thermal power generation, it has attracted the attention of various countries. There are many kinds of media for solar thermal power generation: water, molten salt, air, liquid metal, organic working fluid, etc. Because molten salt has the characteristics of high heat capacity, wide liquid phase temperature range, good fluidity, and strong heat storage characteristics, it is used Its research as a heat-carrying medium ...
