Abstract

The invention discloses a trough type solar middle-high temperature integrated concentrating solar power (CSP) device, and belongs to the technical field of concentrated solar power. The trough type solar middle-high temperature integrated CSP device is composed of parabolic trough condensation arrays, a heat exchanger, a heat accumulation evaporating tank, heat accumulation working medium, an evaporator, steam power machines, a condenser, a complementary boiler and the like. The trough type solar middle-high temperature integrated CSP device adopts a direct steam generation (DSG) heat transfer mode, achieves integral operation of heat transfer, heat accumulation, evaporation, heat supplement through the heat accumulation evaporating tank of the complementary boiler and fused salt and other heat accumulation medium, greatly simplifies integral construction, is favorable for lowering trough trough type concentrating solar power equipment cost, and is favorable for improving temperature of working conditions and power generating efficiency.

Description

technical field [0001] The invention relates to a trough solar medium-high temperature integrated thermal power generation (CSP) device, which belongs to the field of solar thermal power generation. Background technique [0002] At present, the key technical issues in the field of international concentrated solar power generation (CSP) are to continuously reduce the manufacturing cost of solar thermal power generation equipment through technological innovation, continue to improve power generation efficiency, and actively create an economic and technological basis for replacing fossil energy. In the application of invention patents 201110060078.9; 201110086362.3 and 201110161536.8, it is proposed to set up a new type of heat storage and heat exchange integrated device suitable for solar medium and low temperature thermal power generation (CSP), the purpose of which is to reduce the number of solar thermal power generation equipment, reduce heat loss, and improve heat transfer...
