DISTILLATION APPARATUS HAVING CONCENTRIC RISER, EXPANSION AND CONDENSING CHAMBERS

摘要

An apparatus and process for purifying water by distillation and subsequent condensation. The impure water is heated to form a distillate which is moved in a rotational path, expanded condensed and recovered. The recovered condensate contacts only materials not imparting impurities thereto and does not contact the outer shell of the purifying apparatus. Rotational movement is imparted by means of a riser having baffled openings from which the steam exits into an expansion zone.
