Definitions

  • one vacuum chamber made up of two separate chambers with highly heat conductive common wall ( 4 ) is required.
  • One clumber ( 2 ) is for solution of water ( 5 ) and Second chamber ( I ) is for collection of distilled water ( 6 ).
  • Both chamber is connected via air compressor ( 3 ) which w ill transfer saturated ⁇ apour from solution chamber ( 2 ) to distilled water chamber with maintaining presume difference of vapour across both the chambers.
  • the wall of the vacuum chamber is thick enough to resist one ATM pressure against vacuum.
  • Ty pe of Compressor ( 1 ) used in this method may be centrifugal, rotating. reciprocating or w hich ever design is energy efficient to work under low pressure environment Energy efficiency of this method of distillation of w ater depends upon lollow ing factors :
  • This method is generally used at room temperature but in whenever required this method can be used at any lciupcrnlurc by heat insulating vacuum chamber and mamtainmg temperature of distilled water chamber at operating temperatuie for gaming optimum adv antage energy efficiency of this method
  • This method can be used for separation of salt and water from solution ol water

Abstract

L'invention concerne un procédé de distillation d'eau consistant à recycler toute la chaleur latente d'évaporation à vide dans la chambre à vide, à travers une paroi commune conduisant la chaleur. La chambre à vide est composée de deux chambres connectées par un compresseur d'air. L'une (2) des deux chambres contient une solution d'eau (5) soumise à un traitement préalable consistant à éliminer les gaz solubles, et l'autre chambre (1) est destinée à la récupération de l'eau distillée (6) obtenue de la condensation de la vapeur saturée. Après avoir effectué la mise à vide des deux chambres, l'équilibre vapeur-eau est établi à l'intérieur de la chambre. Le point d'ébullition de l'eau est à température ambiante. Le compresseur (3) réduit encore plus la pression dans la chambre (2) en poussant la vapeur saturée dans la chambre (1), générant une différence de pression de part et d'autre de la paroi commune à l'intérieur des deux chambres, ce qui provoque l'ébullition de la solution d'eau dans la chambre (2) et le refroidissement de la paroi (4) conduisant la chaleur. Dans la chambre (1), la pression augmente jusqu'à condensation de la vapeur au-dessus de la paroi commune refroidie, et l'eau distillée est récupérée à l'intérieur de la chambre (1). La chaleur latente d'évaporation de l'eau provenant de la vapeur saturée en condensation est transférée à travers la paroi commune conduisant la chaleur vers l'eau en ébullition.
