Abstract:
A distiller that includes a liquid inlet from which it receives liquid to be purified, that produces purified liquid from liquid entering its liquid inlet, that includes a liquid outlet from which it discharges the purified liquid, and that further includes:A) a rotary-motion source; and B) a rotating assembly so coupled to the rotary-motion source as thereby to be imparted rotary motion about an axis of rotation and including: i) a heat exchanger that includes heat-transfer surfaces that form at least one evaporation chamber to which the distiller directs the liquid to be purified and at least one condensation chamber from which the distiller draws the purified liquid, the heat exchanger providing a heat-exchanger gas outlet by which gas produced in the at least one evaporation chamber can leave the heat exchanger and further providing a heat-exchanger gas inlet by which gas can reach the at least one condensation chamber; and ii) a compressor so coupled between the heat-exchanger gas outlet and the heat-exchanger gas inlet as to maintain a pressure at the heat-exchanger gas inlet higher than that at the heat-exchanger gas outlet.
