ABSTRACT:
The invention is a fluid distillation apparatus (10) which, in its preferred embodiment, includes a cylindrical portion (12) which mates with an end wall (14) and a bell portion (16) to form an enclosed volume (18) within which evaporization and condensation of a selected fluid may take place. A heat exchange rotor assembly (20) is formed of head conductive material and includes intertwined evaporization and condensation channels (52, 54) in spiral array. A central tunnel (58) provides access for vapor from an evaporization volume (24) to a condensation volume (26) with a pressure gradient provided by an impeller (100) urging such passage. A drum motor (68) rotates the drum (40) to facilitate liquid flow in the heat exchange rotor (20). An impure fluid input port (32) and output ports are provided for purified fluid (34), concentrated brine (36) and degassing purposes (38). The apparatus is a flow process device and is especially adapted for continuous purification, such as water distillation or desalinization.
