Steam generation device

摘要

The present invention in several embodiments is an apparatus for producing potable distilled water and solar-thermal energy, as co-products of the generation of steam from sea water by concentrated solar radiation. This apparatus would be comprised of an array an Fresnel lenses of the same or substantially the same focal length which preferably each have an area of approximately 1 square meter, which are oriented in the appropriate 3-dimensional plane in relation to the sun to collect the maximum amount of solar energy over the area of the lens; the lens array would follow or “track” the sun across the horizon in two dimensions. The lens array would focus the collected and concentrated solar radiation in one discrete area of a boiling of several square centimeters, in order to produce steam which is then used to create power and is condensed to provide distilled water.

主权项

1. A solar powered apparatus for generating power and for distilling water in a recirculation free manner, comprising;
a. a boiling vessel in a fluid connection with an inlet water pipe and in a fluid connection with an outlet water pipe, said inlet water pipe in a contact with a body of a fresh water, b. at least one Fresnel lens mounted between said boiling vessel and a solar radiation and operable to generate thermal energy in a response to the solar radiation and transfer said thermal energy to said boiling vessel, said transferred thermal energy sufficient to heat the fresh water entering said boiling vessel through said inlet water pipe, c. a controllable means for moving said at least one Fresnel lens and for directing the solar radiation towards said at least one Fresnel lens, d. a flash steam vessel in a direct fluid connection with said outlet water pipe, said flash steam vessel outputs a distilled water through a first outlet thereof and outputs steam through a second outlet thereof, e. a power generation means coupled to said second outlet of said flash steam vessel, and f. a steam condenser means connected to an outlet from said power generation means for substantially simultaneously dissipating a residual heat in a steam effluent from said power generation means and for condensing said steam effluent to a substantially pure water.
