<p>A water-cooled apparatus (1) for distilling water (53), including a boiler (3), cooling tray assembly (5) and collection vessel (7). As the raw water in the boiler begins to boil, a self-regulating screen (25) rises to float above the raw water, at a height automatically adjusted in proportion to the rate of boil, exposing more and more surface area of the screen as the boiling rate increases. Clean steam rises from a water film (69) formed on the exposed screen surface and enters a condensing area (33) in one of several cooling tray assemblies (5). In each condensing area (33), the coolant water (55) evaporates from its reservoir (31) as the clean steam (70) supplies heat by condensing on the bottom surface (101) of the reservoir. Distillate (105) formed by the condensing steam is then transferred to a collection vessel (7).</p> |
