The present water reclamation system (30) includes a series of concentric thin shells including outer shell (40), intermediate shell (32), and inner shell (34). The shells mount within a housing (50) that can be maintained under vacuum or low pressure. The shells rotate at high velocity. Contaminated liquid from outside the housing is injected into the space between half the shells. The centrifugal force causes the liquid to form a thin film along the inward facing surface of the shell. A compressor (220) lowers the pressure adjacent the thin film causing the liquid to boil. The compressor carries the vapor to the other side of those shells at a slightly higher temperature. There the vapor encounters the wall, which is cooler because its heat was transferred to boil the contaminated liquid. The vapor condenses, and rotation throws the condensate against the adjacent wall where it is collected. When condensing, the heat of condensation transfers to the shell for boiling the incoming contaminated liquid. The system (30) needs no heat sources other than the energy of vapor compression to complete the cycle flow from vaporization to condensation.

Le système d'assainissement des eaux (30) de la présente invention comprend une série de fines coques concentriques, à savoir, une coque extérieure (40), une coque intermédiaire (32) et une coque intérieure (34). Les coques se montent dans un logement (50) qui peut être conservé sous vide ou sous faible pression. Ces coques sont en rotation à grande vitesse. Le liquide pollué de l'extérieur du logement est injecté dans le volume entre la moitié des coques. La force centrifuge amène le liquide à former un film fin le long de la face interne de la coque. Un compresseur (220) abaisse la pression au voisinage du film fin, ce qui provoque l'ébullition du liquide. Le compresseur fait passer la vapeur de l'autre côté des coques à une température légèrement supérieure. A cet endroit, la vapeur rencontre la paroi qui est moins chaude parce que sa chaleur a été transférée pour faire bouillir le liquide pollué. La vapeur se condense et la rotation propulse le condensat contre la paroi adjacente où ce dernier est recueille. Pendant la condensation, la chaleur dégagée se transfère à la coque faisant bouillir le liquide pollué entant. Le système (30) n'a pas besoin d'autres sources de chauffage que l'énergie de la compression de vapeur pour achever le cycle vaporisation-condensation.
