Abstract
An evaporation product discharged from a lower end a falling-film evaporator enters a downpipe ( ), makes a 180° turn at a bottom of the downpipe, and moves upward through an annular rising channel ( ) defined between the downpipe and an intermediate housing ( ). As the evaporation product moves along a spiral path ( ) defined by the spiral fins, centrifugal forces urges water droplets and impurities to a radial outward periphery where they pass through openings ( ) in the intermediate shell as pure steam continues through the spiral path and out a pure steam outlet ( ). A cooling jacket ( ) chills a peripheral wall of an outer shell ( ) adjacent the holes such that the discharged water droplets condense on the outer shell and flow down a reject water return path to a reject water reservoir at the bottom of the outer shell.
