ABSTRACT:
In an apparatus for the desalination of sea water using a multi-effect evrator process, a sea water preheater and a falling film evaporator are both formed of similar stamped heat exchanger plates. The heat exchanger plates have a uniform arrangement of projections-depressions disposed in a grid-like manner with rows of the projections-depressions extending perpendicularly to one another. The plates are assembled in facing contact so that one pair of plates form tubular ducts and adjacent plates on each side of the pair combine with the plates forming the tubular ducts and provide slot-like ducts separated from and extending perpendicularly to the tubular ducts. Adjacent plates are welded together. The plates in the preheater form a continuous unit divided into stages. The plates in the falling film evaporator are arranged in individual units with each unit forming a separate stage.
