Solar boiler photo-thermal module

Abstract

The invention provides a solar boiler photo-thermal module, belonging to solar thermal utilization technology in the field of new energy or renewable energy. The existing solar thermal utilization technology is mainly capable of solving problems of high focusing ratio, high efficiency, large capacity and low cost. A single photo-thermal tube and a focusing cover are adopted for the photo-thermal module; the focusing cover is capable of tracking the sun in all directions, simplifies an automatic tracking device, sharply reduces the cost and fully improves the solar energy utilization efficiency; the focusing cover is a parabolic cylinder, and the opening area can be large; and the photo-thermal tube is arranged on the axis of the focus of the focusing cover, which is beneficial for improving the focusing ratio. The photo-thermal tube is a vacuum glass tube, and is internally provided with a heat absorption core pipe with a spiral medium passage so as to more uniformly absorb heat by the medium. The photo-thermal module is capable of not only providing hot water, but also providing steam with a certain temperature and a certain pressure; and moreover, a large unit capacity can be obtained to satisfy requirements of combined generation and supply of heat, electricity and cold.
