Problems solved by technology

Hydropower and wind power are clean energy sources, but due to limited resource conditions, they are far from meeting the growth needs of human material life
Although irradiated solar energy has many advantages, the collection method is not perfect, limited by the sunshine in the day and night, the energy flux density is low, the development cost is high, and it is difficult to popularize and use

example 1

[0029] An air energy power plant is built in a township, the total vertical height of the pipes is H=100 meters, the flow cross-sectional area of ​​the air outlet at the top is 12 meters in diameter, and the area is A 2 =113.m 2 , the inner diameter of the seat ring of the throat air turbine is 3 meters, and the flow cross-sectional area A=7.06 meters 2 . At this time, the pipeline system can produce the maximum flow rate, and the correction coefficient Φ=0.9 is taken, Take the rated air velocity V at the end of the pipe 2 =10m / s, then the flow in the pipe Q=V 2 A 2 =10×113.1=1131 meters 3 / second, take the air gravity γ = 12.26 N / m 3 , efficiency η=0.75, then the air energy power plant can obtain power:

[0030] N=γH·Q·η=12.26×100×1131×0.75=1040 kilowatts.

example 2

[0032] A city builds an air energy power plant, the total vertical height of the pipeline is H=400 meters, the cross-sectional diameter of the air outlet at the top is 51 meters, and the area is A 2 = 2000 meters 2 , The inner diameter of the throat air turbine seat ring is 14 meters. Flow cross-sectional area A = 154 meters 2 , at this time the pipeline system can produce the maximum flow rate, take the correction coefficient Φ=0.9, Take the rated air velocity at the end of the pipe: V 2 =20m / s, then the flow in the pipe Q=V 2 A 2 =20×2000=40000 meters 3 / second, take the air gravity γ = 12.26 N / m 3 , efficiency η=0.75, then the air power plant can obtain power:

[0033] N=γ·H·Q·η==12.26×400×40000×0.75=147000 kilowatts.

[0034] It can be seen from the above example that increasing the air column height H and the cross-sectional area A increases the flow Q, and the power of the power plant increases greatly. One unit of air energy power station can get a lot of p...

Abstract

The present invention is air energy power-generating method. One vertical pipe is set from the ground to upper air, air as working medium is compressed by gravitational attraction and air inside the pipe is expanded to obtain energy owing to heating of the light and heat of the sun. The cooperative action of air inside the pipe and air outside the pipe drives the air energy power generators to produce electricity. The present invention provides one green energy source and is clean, rich, low in cost and safe.

Description

Technical field: [0001] The invention relates to a method for generating power by using solar energy, especially using solar energy to heat the air, so that the hot-pressed air in the vertical tube on the ground itself produces upward expansion force and the buoyancy force generated by the pressure of the air column outside the tube, which jointly act on the air in the tube, and Obtain high-speed airflow to drive the air turbine generator set to rotate and generate electricity by air energy. Background technique: [0002] Since human beings began to use firewood and forests as energy sources for their own heating and cooking, with the increase of population and the needs of industrialization, in addition to vigorously cutting down forests, human beings have also used underground coal, oil and natural gas, nuclear energy, etc. Dig it out and use it. More than 80% of the electric energy used by human beings is generated by utilizing geological and mineral resources. Due to t...
