Concrete condition understands the concrete meaning of above-mentioned term in the present invention.
As shown in Figure 1, the present invention increase carbon dioxide layer salt gradient solar pond include lower troposphere 6, non-convection layer 5,
Higher troposphere 4 and carbon dioxide layer 7, the higher troposphere 4, the non-convection layer 5 and the lower troposphere 6 are successively from upper
To lower setting, the carbon dioxide layer 7 is between lower troposphere 6 and non-convection layer 5；Sunlight enters the shortwave 1 of the earth, leads to
Solar pond higher troposphere 4 and non-convection layer 5 are crossed, carbon dioxide layer 7 is passed through, lower troposphere 6 is reached, is absorbed and store up by lower troposphere 6
It deposits；And the long wave 2 that lower troposphere 6 dissipates upwards can be reflected when encountering carbon dioxide layer 7, be returned to lower troposphere 6；And
And carbon dioxide layer 7 is also distributing long wave around, a part of long wave 3 can be absorbed by lower troposphere 6, can make lower troposphere 6
Temperature improves.
Carbon dioxide layer 7 is by upper transparent glass piece, lower transparent glass piece, import insulation sheet 11, outlet heat-insulating material
Piece 10 and the carbon dioxide inlet 8 in import insulation sheet 11, the titanium dioxide in outlet insulation sheet 10
9 composition of carbon outlet, wherein upper transparent glass piece is located at 5 bottom surface of non-convection layer, and lower transparent glass piece is located at lower 6 top surface of troposphere,
Carbon dioxide inlet 8 is located in import insulation sheet 11, and carbon dioxide outlet 9 is located in outlet insulation sheet 10, import
Insulation sheet 11 and outlet insulation sheet 10 are located at left and right sides of the carbon dioxide layer and are symmetrical arranged, medium two
Carbonoxide, the area of upper transparent glass piece, lower transparent glass piece in the carbon dioxide layer 7 respectively with non-convection layer bottom surface face
Long-pending, lower troposphere top surface area is identical, and import and export insulation sheet is in same plane with solar pond the right and left respectively.
As shown in Fig. 2, be filled with carbon dioxide by carbon dioxide inlet 8 in solar pond work, close carbon dioxide into
Mouth 8, the shortwave of sunlight reaches lower troposphere 6 through carbon dioxide layer and is stored, and the long wave meeting that lower troposphere radiates upwards
It is reflected by carbon dioxide layer, forms greenhouse effects, reach heat preservation, improved the purpose of lower troposphere temperature, improve heat accumulation efficiency.
As shown in figure 3, when solar pond does not work, carbon dioxide outlet 9 is opened, extract out after carbon dioxide and is stored, is closed
Carbon dioxide outlet 9 is closed, import insulation sheet 11 is opened, is put into heat-insulating material, closes import insulation sheet 11, further
It reduces lower 6 dissipation heat of troposphere and reaches heat insulation effect, reduce heat loss, improve heat accumulation efficiency.When working again, beat
Mouthful insulation sheet 10 is outputed, heat-insulating material is taken out, closes outlet insulation sheet 10, then the carbon dioxide of storage is led to again
It crosses carbon dioxide inlet 8 and is filled with carbon dioxide layer.
The course of work approximately as:
Solar pond mechanism of the present invention is based on greenhouse effects and increases by one layer of carbon dioxide between lower troposphere and non-convection layer
Layer reentries a certain amount of carbon dioxide to carbon dioxide layer by carbon dioxide inlet, due to dioxy when solar pond is started to work
Changing carbon can be through shortwave, reflection long wave, so the part that the wave that the sun issues passes through atmosphere is shortwave, shortwave passes through upper convection current
Layer and non-convection layer pass through carbon dioxide layer and reach lower troposphere, stored by lower troposphere, will not influence the normal work of solar pond
Make, and the wave given out from lower troposphere is long wave, and lower troposphere can be reflected back by carbon dioxide layer reaching carbon dioxide layer,
The internal energy for reducing solar pond scatters and disappears, while carbon dioxide can also distribute long wave around simultaneously, and a part of long wave can be straight
It connects to be absorbed by lower troposphere and store, improve down tropospheric temperature；When solar pond does not work, taken out by carbon dioxide outlet
It carbon dioxide and stores out, then by import insulation sheet, is filled with heat-insulating material to the layer, completely cut off lower troposphere and dissipate upwards
Heat；When working again, the carbon dioxide of storage is filled with carbon dioxide layer again through carbon dioxide inlet.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of protection of the claims
Subject to.
