Solar vacuumizing hydraulic electrogenerating system, and operation method thereof

Abstract

The invention provides a solar vacuumizing hydraulic electrogenerating system, and an operation method thereof. The system comprises a solar thermal collector, a steam injector, a condenser, a water circulating pump, a first water storage tank, a hydraulic turbine, a generator and an impounding reservoir; the upper end of the first water storage tank is connected with the steam injector through a first water pipe with a first valve; the lower end of the first water storage tank is connected with the water inlet end of the hydraulic turbine through a first pipeline with a fourth valve; the water outlet end of the hydraulic turbine is connected with the generator; the solar thermal collector, the steam injector, the condenser, and the water circulating pump are sequentially connected through pipelines to form a loop; the upper end of the first water storage tank is also provided with a first ventilating pipe with a second valve and the lower end of the first water storage tank is also provided with a second pipeline with a third valve; and the second pipeline is extended into the impounding reservoir. Compared with other solar thermal power generation devices, the solar vacuumizing hydraulic electrogenerating system has the advantages that: equipment is relatively simple, the manufacturing technology is mature, and cost is relatively low.

Description

【Technical field】 [0001] The invention relates to the technical field of solar energy, in particular to a power generation system utilizing solar energy. 【Background technique】 [0002] In order to solve and respond to problems such as energy shortage and environmental degradation, in recent years, governments of various countries have continuously increased capital investment, demonstration, promotion and industrialization of renewable energy research, and the proportion of renewable energy in China's energy consumption structure Increase year by year. Among them, solar energy resources have development conditions and values ​​unmatched by other renewable energy sources due to their wide distribution, large total resources, cleanliness and pollution-free characteristics. Most of my country is located south of 45° north latitude. Two-thirds of the country's land area has an annual sunshine time of more than 2200h, and the total annual solar radiation per square meter is 334...

AI Technical Summary

Problems solved by technology

In terms of solar power generation, solar photovoltaic power generation has commercialized power stations in operation, but it has disadvantages such as low photoelectric conversion efficiency, large footprint, high requirements for lighting conditions, and high manufacturing costs of solar photovoltaic cells.

At present, solar thermal power generation mainly includes three types: trough type, tower type, and dish type. The system is relatively complicated and the manufacturing cost is relatively high.
