Abstract
A solar desalinator that converts contaminated water to potable water includes a cylindrical solar collector, a trough-shaped parabolic mirror, and a condenser. The solar collector is positioned within the trough-shaped parabolic mirror, and the parabolic mirror focuses the Sun's rays onto the solar collector, heats the water, and converts the water to steam. The steam is fed to the condenser where the steam is condensed to recover potable water. The solar collector includes an inner conduit surrounded by an outer shell with a vacuum in the anger space between. Energy absorbing material in the form of dark metal is positioned in the inner conduit. A residue bulb is attached at the contaminated water inlet to collect residue left by the creation of the steam.
Claims9
A solar desalinator for removing contaminants from contaminated water to produce potable water comprising:
- a. a source of contaminated water;
- b. a solar collector for receiving the contaminated water comprising:
- i. an inner conduit having in internal wall defining a volume, a center line, a collector inlet for receiving the contaminated water, and a collector outlet for delivering steam;
- ii. an outer shell surrounding the inner conduit defining an annular vacuum space between the inner conduit and the outer shell;
- iii. a silicone stopper positioned adjacent the collector outlet capable of blocking water from the collector outlet but transmitting steam to the collector outlet;
- and
- iv. a heat absorbing material positioned within the inner conduit;
- c. a parabolic mirror configured as a trough, extending parallel to the solar collector, and having a focal line coincident with the center line of the inner conduit;
- and
- d. a condenser for receiving the steam from the collector outlet of the inner conduit and condensing the steam into potable water.
