Abstract

L'invention concerne un procédé et un dispositif de production d'eau pure, ledit dispositif étant un dispositif de préférence transportable et approprié pour être raccordé à un robinet d'eau d'une installation d'alimentation en eau domestique, dispositif dans lequel l'eau brute est chauffée à une température d'évaporation. Le processus de chauffe peut être exécuté par répartition de l'eau brute entre différents étages de pression. A l'exception de l'étage où la pression est la plus élevée, la vapeur provenant d'un étage précédent à pression supérieure est utilisée comme caloporteur pour l'évaporation de l'eau brute dans un étage suivant à pression inférieure. En variante, la vapeur d'eau produite peut également être comprimée et la vapeur d'eau comprimée peut être utilisée pour faire chauffer et faire évaporer l'eau brute. Le processus de chauffe peut également être mis en oeuvre pour permettre l'évaporation et la condensation de la vapeur produite à l'aide d'un fluide caloporteur circulant dans le circuit, à la manière d'un processus à pompe à chaleur.
