Abstract
A falling film evaporator having a shell pass, multiple tubes parallel to each other, a condensed steam outlet, an inlet for an aqueous solution on the top of the tube pass, an outlet for the aqueous solution at the bottom of the tube pass, a distributing assembly having a plurality of distributing trays arranged vertically from top to bottom in incremental diameters and each having multiple holes, and a plate for collecting the aqueous solution below the distributing assembly. The tubes are straight and installed vertically in the evaporator; inner wall of the tubes is smooth, and the top portion of the tubes is protruded above a horizontal plane of the plate. The evaporator is particularly useful for concentrating an aqueous solution containing thermosensitive materials.
