This invention is an apparatus for water purification by distillation. It consists of an upper compartment which is its primary condenser, and a lower compartment which stores the unpurified cold and partly heated water and a heating unit which changes this water into steam. The primary condenser converts the steam into distilled water by means of a number of spiral coolant tubes; and any water vapor or steam which escaped the condensing action in the primary condenser is carried to a secondary condenser in which the condensation is completed. The invention is also provided with means for returning overflow boiling water, and partly heated coolant water from the cooling coils, back to the lower compartment water supply, to be boiled again.

A water-distillation apparatus built of non-corrosive materials and comprising, in combination, an enclosed, generally cylindrical container, a divider plate in an intermediate potion of said container dividing said container into an upper chamber and a lower chamber, an upright tube in said lower chamber and communicating with a central portion of said upper chamber, heating means within said upright tube, a perforated container positioned at the top of said upright tube and containing balls for separating boiling water and vaporized water so that the boiling water can be returned to said upright tube, a plurality of coiled tubes in spaced, generally horizontal planes in said upper chamber, means forming a condenser chamber located outside said cylindrical container, a centrally-located tube in said upper chamber extending through said plurality of coils, a first outlet pipe communicating with the upper end of said central tube and extending through said condenser chamber, a second outlet pipe communicating with the lower end of said upper chamber and with said first outlet pipe, a return pipe communicating with the uppermost one of said coiled tubes and with the lower end of said upright tube for supplying heated water from said coiled tubes to said upright tube, a supply water pipe for supplying water to be distilled to said condenser chamber around said first outlet pipe and for supplying water to be distilled to the lowermost one of said coiled tubes in said upper chamber, whereby water is supplied to said upright tube through said condenser chamber and through said coiled tubes.
