Solar distillation apparatus

Claim 1

A solar distillation and desalinization apparatus comprising: a. a heating chamber having a transparent top convex dome, said dome adapted to receive solar radiation, b. the interior of said dome being provided along its internal periphery with a continuous gutter, c. said dome being provided with a pluralIty of radial, arcuate, sea-water conveying condenser tubes connected between a central feed header at the top of said dome and an annular tube lying said continuous gutter along the inner surface of said dome, d. said dome being provided on its external periphery with a vertically disposed concave part cylindrical solar energy condensing reflector, e. a sea water supply tank positioned at a level above said solar heating chamber, f. means for controlling the output from said sea water supply tank including a motor operating electrical switch supported by said supply tank, a vertically movable float adapted to be actuated by sea water within said tank and whose vertical position controls said electric switch to activate a pump motor at low water level and inactivate the motor at high water level, a pump connected to a source of sea water and whose output is coupled to said supply water tank for supplying sea water thereto, the operation of said pump being controlled by the actuation of said electrical switch as indicated, g. a condenser tank having condensate conveying coils in fluid receiving communication with said peripheral gutter, h. a liquid conveying conduit connecting said condenser tank and the interior of said heating chamber for feeding warmed sea water to said chamber, h''. a sea water conveying conduit connecting said annular tube and the condenser tank i. float controlled valve means connected to the terminus of said last mentioned tube and positioned within said condenser tank for controlling the level of liquid in said condenser tank, j. a filter bed, the output of said condenser coils feeding the top of said filter bed, k. conduit means for receiving the output from said filter bed and leading to a fresh water reservoir tank.
