Heat collectors for solar energy hot blast power generation system

Abstract

The present invention relates to a heat collector for solar hot air power generation system, includes solar chimney, heat collectors, transparent material spacing plate disposed vertically along circular tangential direction with 0.8-2 m which is the same center of circle of heat collectors, lower edge of transparent material spacing plate clings to floor of heat collectors, upper edge clings to ceiling of heat collectors; the apparent material spacing plate divides heat collectors into at least 24 regions equally along circumference; outer edge of apparent material spacing plate through to outer margin of heat collectors, and its length is 60-110m. The present invention improves Plate solar energy collector heat collecting stripe heat-collecting efficiency of solar hot air power generation system heat collectors, thereby improving its generating efficiency. Because of increasing heat collectors heating surface, so reducing heat dissipation losses of heat collectors; guiding function of plate glass to air current reaches airflow request when reaches air arriving turbine generator entrance, flowing loss of airflow is decreased.

Description

technical field [0001] The invention belongs to the technical field of energy and electric power, in particular to a heat collector used in a solar thermal wind power generation system. Background technique [0002] As the global energy crisis becomes increasingly prominent, the development of new energy sources is a common need of all mankind. Solar hot wind power generation technology is a new way to realize large-scale development and utilization of solar energy, and it is one of the effective ways to solve my country's energy crisis ([1] Zhang Jianfeng, Yang Jiakuan, Xiao Bo, etc. Current status and prospects of solar chimney power generation technology [J ]. Renewable Energy, 2003(1): 5~7; [2] Zhao Yuwen. The development and future trend of solar energy utilization [J]. China Electric Power, 2003, 36(9): 63~69). [0003] Solar thermal wind power generation technology was first proposed by German Professor J.Schlaich in 1978. Its principle is to use solar collectors and ...
