4, the sunlight direct projection is to unidirectional focusing reflective mirror 11, unidirectional focusing reflective mirror 11 focuses on sunlight the position at heating tube 12 places, at this moment, the heat that sunlight focuses on the back generation just begins heating with the cold water in the heating tube 12, and the water of heating flows in the water tank 2 by water loop hose 3, and the cold water in the water tank 2 is by being heated in an other water loop hose 3 inflow heating tubes 12.
5, by the circulation heating of step 4, the cold water in the water tank 2 all is heated, and again steam (vapor) outlet 25 just can will be emitted utilization because of the steam that produces behind the cold water in the heating water tank 2.
6, in step 5, when steam is emitted, charge into cold water by water inlet pipe 21 again, and because hot water can rise, cold water can sink, so charge into the bottom that cold water can directly sink to water tank 2 from water inlet pipe 21, flowing into heating tube 12 by water loop hose 3 again is heated, after hot water in the water tank 2 then rises, emit steam, steam is emitted utilization by steam (vapor) outlet 25 again.
By steam (vapor) outlet 25 is connected steam engine, steam engine just can drive generator for electricity generation, and the generated output size is directly proportional with the size of heating tube 12.To organize heating tube 12 more and be used in combination, just can enlarge generated output.
By steam (vapor) outlet 25 is connected heating equipment, namely can be with the steam heat supply that produces.
By outlet pipe 22, also can emit hot water.
If in water tank 2, charge into seawater, then connect the distillation cooling device by steam (vapor) outlet 25 and can obtain distilled water.And by the seawater of outlet pipe 22 (salinity) of emitting high concentration regularly, import the seawater of (salinity) of normal concentration again this moment by water inlet pipe 21.
By embodiment 4 this heating tubes 12, the capacity of increasing metal tube 122 that can be unlimited increases the result of use of the steam boiler of the unidirectional focusing of employing sunshine of the present utility model heating.
Among above-described embodiment 1, embodiment 2 and the embodiment 3, unidirectional focusing reflective mirror 11(is as shown in Figure 8) can be the rectangular plane mirror of multi-angle or arc reflective mirror; The rectangular plane mirror of multi-angle is made of arc mirror holder and minute surface, and minute surface then is made of some level crossings, and the minute surface of level crossing is all set certain angle, namely reverberation can be focused on.This reflective mirror cost is low, and manufacture is simple.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
