Solar hot air generation device

Abstract

The invention provides a solar hot air generation device and relates to a solar power generating device. The solar hot air generation device consists of a solar heat collector, an air heater, an acceleration air pipe, a first windmill generator, a wind wheel a, a wind wheel b, a transmission shaft and an air draft pipe, wherein the air heater is composed of a casing and a heat exchanger installed in the casing, a lower-portion space of the air heater forms an air return chamber, an upper-portion space of the air heater forms an air heating chamber, and the heat exchanger is arranged in the air heating chamber. An inner space of the acceleration air pipe comprises a contraction cavity and a diffusion cavity, wherein a first generating unit is arranged in the inner space of the acceleration air pipe. The acceleration air pipe is installed at the upper end of the air heater, the air draft pipe is installed at the upper end of the acceleration air pipe, a water outlet of the solar heat collector is connected to a hot water inlet of the heat exchanger, a return water outlet of the heat exchanger is connected to a water inlet of the solar heat collector. Compared with photovoltaic power generation, the solar hot air generation device has the advantages of being low in construction cost, simple to maintain and low in maintenance cost.

Description

technical field [0001] The invention relates to a power generating device, in particular to a solar power generating device. Background technique [0002] Wind energy is a clean, safe and renewable green energy. The use of wind power does not need to use fuel, nor will it produce radiation or air pollution. It has no damage to the ecology, and has good environmental protection and ecological benefits. It is of great significance to the sustainable development of human society. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through the speed-increasing mechanism to promote the generator to generate electricity. According to the current windmill technology, a breeze speed of about three meters per second can generate electricity. [0003] Our country is very rich in natural wind resources, and the technology of using wind power to generate electricity is quite mature. Therefore, ther...
