5, by the circulating-heating of step 4, the cold water in water tank 2 all is heated, then vapor outlet port 25 just can will be emitted utilization because of the steam that produces after the cold water in heating water tank 2.
6, in step 5, when steam is emitted, be filled with cold water by water inlet pipe 21 again, and because hot water can rise, cold water can sink, so be filled with from water inlet pipe 21 bottom that cold water can directly sink to water tank 2, flowing into heating tube 12 by water circulation flexible pipe 3 again is heated, after hot water in water tank 2 rises, emit steam, steam is released utilization by vapor outlet port 25 again.
By vapor outlet port 25 is connected steam engine, steam engine just can drive the generator generating, and the generated output size is directly proportional to the size of heating tube 12.To organize heating tube 12 more and be used in combination, just can enlarge generated output.
By vapor outlet port 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 be filled with seawater in water tank 2, connect the distillation cooling device by vapor outlet port 25 and can obtain distilled water.And by the seawater of outlet pipe 22 (salinity) of emitting high concentration regularly, then pass through the seawater that water inlet pipe 21 is inputted (salinity) of normal concentration this moment.
By this heating tube 12 of embodiment 4, 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 invention heating.
In above-described embodiment 1, embodiment 2 and embodiment 3, unidirectional focusing reflective mirror 11(is as shown in Figure 8) can be the rectangular plane mirror of multi-angle or curved reflection mirror; The rectangular plane mirror of multi-angle is made of arc mirror holder and minute surface, and minute surface 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 is only a specific embodiment of the present invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
