Abstract

This invention discloses a building method of solar energy funnel electricity-generating device. This solar energy funnel electricity-generating device consists of the heat-adding shed, solar funnel and the spiral generator unit. Building the heat-collecting shed on the bevel face of the slope is benefit to direct at the sun, to enlarge the effective surface that the heat-collecting shed can obtain the sun rays, to enhances the efficiency. Fixing the solar energy funnel on the top of slope, can improve the height of the funnel with no or little building cost, and improve the efficiency of the system and reduce the electricity generating cost of system. The top of the heat-collecting shed communicated with the bottom of the funnel, the floor of the heat-collecting shed paves stones evenly or insulating layer. Paving insulating layer can obtain large quantity of electricity generation and apply to merge and synchronize two or more power grids. Paving stones and part-dividing of heat-collecting shed can obtain the regular quantity of electricity generating. This device can be used as an independent electricity-supplying system.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a construction method of a solar chimney power generation device. Background technique [0002] Solar chimney power generation technology is a new technology favored by many energy experts. The idea of ​​building a solar chimney power station was proposed by Professor Jorgen Schleich from the University of Stuttgart. The solar chimney power generation system consists of three basic parts: solar heat collection shed, solar chimney and turbine generator set. The solar heat collection shed is built on a piece of land with strong solar radiation and good heat insulation performance; there is a certain gap between the heat collection shed and the ground to allow the surrounding air to enter the system; a tall chimney is installed at a certain distance from the center of the heat collection shed to the ground. At the bottom of the chimney there is a turbine. When the sun shines...
