Abstract

L'appareil comprend une ou plusieurs colonnes verticales 1 divisées en plusieurs parties cylindriques. Chaque partie constitue un étage comprenant un ou plusieurs évaporateurs à film formés par des tubes verticaux 5, une seule cuve 3 destinée à recueillir la saumure et dont la section est circulaire, cette cuve étant pourvue d'ouvertures latérales supérieures, un système de vanne 11, un ou plusieurs tubes de siphonage et un ou plusieurs préchauffeurs comportant les tubes verticaux 6 mandrinés dans les mêmes plaques tubulaires 7 que les tubes verticaux des évaporateurs à film. L'appareil comprend également des tuyaux 8 et des boîtes à eau 9 placés à l'intérieur des cuves pour raccorder les préchauffeurs des divers étages ainsi que des tuyaux entre les étages et un condenseur final à faisceaux de tubes disposés en-dessous du dernier étage.
