Abstract
The disclosure relates to an improved solar water purification apparatus. More specifically, it relates to a solar water purification apparatus that includes a first and second preheater, an evaporation load tank, condenser, and pure distillate collecting tank. The condensing surface is a domed upper structure which includes a corrugated inner surface to increase the condensing surface. The outersurface of the domed upper structure is likewise corrugated and completely enclosed by a first preheater chamber the permit efficient cooling of the domed upper structure and encourage rapid condensation, thus transferring heat from the interior corrugations to the exterior corrugations of the first preheater chamber, further adding to the overall thermal efficiency. After the load, which is any form of polluted water including seawater, is preheated in the first preheater chamber, it is directed to the an external solar operated preheater from which it is directed into the load evaporation tank within the domed upper structure where it evaporates and condenses on the internal corrugated surface of the domed upper structure and flows by gravity into a distillate collecting tank which is inverted mirror image of the domed upper structure. Back-up electrical heater units are provided for periods of cloudy days.
