All-weather solar heat power generation system with peak regulation function

Abstract

The invention relates to a solar heat power generation system which is composed of a groove-type solar condensation and heat accumulation device, a first heat storage device, a steam generator and a second heat storage device, wherein heat accumulating pipes the interiors of which are filled with molten salt are arrayed at an optical focus position of the condensation and heat accumulation device, and the molten salt is used for storing the heat energy of the sun; the first heat storage device is connected with the heat accumulation pipes and is used for storing the molten salt which is heated by the sunlights; the first heat storage device is connected with the steam generator, exchanges energy with water in the steam generator, and changes water into saturated vapor to enter a steam turbine to do work in an expansion mode; the steam generator is connected with a second heat storage device; the second heat storage device is connected with the heat accumulation pipes; and the molten salt after energy exchange in the steam generator enters the heat accumulation pipes through the second heat storage pipe, thus circulation is formed. The system provided by the invention has the characteristics of high efficiency, heat accumulation function, good heat storage performance, good continuity, low cost and the like.

Description

technical field [0001] The invention relates to a solar thermal power generation system, in particular to a trough solar thermal power generation system. Background technique [0002] As one of the main driving forces for the advancement of civilized society, energy utilization technology occupies a pivotal position in the development of human society. In the past century, the development and utilization of petrochemical energy such as coal, oil, and natural gas has opened the prelude to the era of large industries. After 100 years, the total annual energy supply of human beings has increased by 10 times. However, unrestrained resource development and inefficient energy utilization have caused a large amount of resource waste and increasingly serious ecological environment pollution, and the living space of human beings has been greatly threatened. In the new century, energy science has to face Due to the dual pressure of resource shortage and environmental pollution, peopl...
