Description
The present invention is the hydraulic potential that solar energy, energy wind energy from low energy current density become high water level, becomes the method and the mechanical device of the energy of high fluence density.
Understand according to interrelated data, do not have similar technology report.
The hydraulic potential that solar energy, wind energy become high water level can generate electricity, irrigate, and the energy is provided, improves the ecological environment, develops production.Can also accelerate the new and renewable sources of energy development speed, form solar energy, a wind energy and transfer hydraulic potential generating to, irrigate the energy that green plants the absorbs solar energy pattern that develops at a progressive speed.
One, solar energy changes lowpressure energy principle, device, characteristics into.
Principle is that the gas volumetric expansion of being heated produces the air pressure energy.
Figure [1] is that solar energy changes lowpressure energy device into, and 1-solar thermal collector, 2-intensification chamber, 3-chimney, 4-low-temperature receiver storehouse, 5,6-gas-turbine, 7-compression pump, 8-low-temperature receiver pneumatic tube, the heat insulation tarpaulin of 9-, 10-air-flow go out the Pneumatic water pump pipe among the figure, the suction engine pipe is pressed in the air inlet of 11-air-flow.
Energy transformation method: solar energy is that the cold and heat source energy crosses, and cool air kelvin temperature is raise 70～80 ℃, and becoming lowpressure can do work.
Thermal source is the hot air on the solar thermal collector, as the dull and stereotyped air thermal collector of long strip, and long strip column paraboloid mirror heat collector, heat source temperature is more than 100 ℃.
Low-temperature receiver one is a low ambient temperature, the 2nd, and artificial low-temperature receiver.
Low ambient temperature, also subzero, available interiorly underground water, soil are lowered the temperature at plateau some places in summer.Subzero 10～35 ℃ of China the north, west area winter temperature will be at artificial low-temperature receivers in the coldest season, as large-scale cellar for storing things ice, and blizzard, utilizing gully, mountain depression ice storage, snow is saving of labor, the artificial low-temperature receiver in labour-saving.
Energy conversion process: the air in low-temperature receiver storehouse (4), enter intensification in the solar thermal collector (1) by pipeline, temperature reaches more than 100 ℃, gas expands and rises along the straight-through gas-turbine (5) of pipeline, in addition the two-way cool air enters intensification chamber (2) expanded by heating by pipeline (8) and rises to chimney and promote gas-turbine (6) [gas-turbine (5) is same rotatingshaft with (6) in fact, just with the gas road of differing of originating].Every gas-turbine that can start is turned over, and no matter rotating speed is fast, slow, drives the compression pump gas transmission and pumps up water with regard to doing work, and making solar energy is hydraulic potential.
Can compile the air pressure of counting this energy conversion device formation of cover is huge making a concerted effort, and just the high-lift big flow of energy pumps up water.
If solar radiation intensity is at 1kw/m
2About, sink temperature is at subzero degree more than 20 ℃, and available gas-turbine directly drives generator for electricity generation.
