Abstract
A multistage flash-evaporator for producing soft water from a saline water, comprising a shell forming a pair of lobes enclosing therebetween a spinal portion in symmetrical arrangement with respect to a vertical longitudinal mid-plane. The top and bottom walls of the spinal portion are, in cross-sectional shape, circular arcs having their centres of curvature on the said mid-plane, while the lobes are polycentric curves each of which has its centres of curvature on a plane parallel to the mid-plane. A specifically shaped hood arrangement in the shell is provided to define in each stage a condensation chamber centrally located between a pair of evaporation chambers.
