Mountain massif shaft-well chimney highly effective solar energy hot gas flow generating system

Abstract

The invention discloses a high efficient solar hot-gas generating system of mountain impact chimney. It is one generating device in facilities utilizing solar thermal energy which can regenerate green energy. It is characterized in that: it contains hot-gas duct system of heat collecting and retaining unit, hot-gas heat-collecting system of heat collecting and retaining unit of mountain body slope and generating system. The hot-gas duct system contains mountain body, peak chimney on top of it, mountain chimney inside it and mountain flat cavity. The flat cavity connects with the upper hot-gas linking duct, hot-gas duct of heat collecting and retaining unit of mountain body slope, lower cool-gas linking duct and cool-gas inlet duct of generator in sequent. The invention is the most economical generating mode with high-benefit, which has smallest investment, lowest cost, most simple structure, most rapid constructing speed, longest serve years and without pollution discharging or destroying ecological environment.

Description

(1) Technical field [0001] The invention relates to a high-efficiency solar thermal airflow power generation system of a mountain shaft type chimney, which is a renewable green energy power generation device among solar thermal energy utilization equipment. (2) Background technology [0002] At present, the invention patent application number: 98104903.6 "Hillside Solar Greenhouse Wind Generation System" and other invention patents, and Spain built the world's first solar thermal power station in 1982, its common disadvantages: 1. Solar heat collection sheds are all used The plastic film is used as a heat collecting material, so the temperature difference between the inside and outside of the heat collecting shed is small (about 20°C), that is, the heat collecting temperature is low. Poor thermal insulation performance, low heat collection efficiency, and short service life; 2. The heat storage adopts stone paving on the ground and thermal insulation layer. This heat storage...

[0002] At present, the invention patent application number: 98104903.6 "Hillside Solar Greenhouse Wind Generation System" and other invention patents, and Spain built the world's first solar thermal power station in 1982, its common disadvantages: 1. Solar heat collection sheds are all used The plastic film is used as the heat collecting material, so the temperature difference between the inside and outside of the heat collecting shed is small (about 20°C), that is, the heat collecting temperature is low

Poor thermal insulation performance, low heat collection efficiency, and short service life; 2. The heat storage adopts stone paving on the ground and thermal insulation layer. This heat storage method has low efficiency and is difficult to adjust and control; 3. The slope chimney only acts as an air duct. Therefore, the chimney utilization rate and power generation efficiency are low

In short, the existing solar thermal power generation systems in the world currently have the problem of low power generation efficiency.
