Abstract
There is provided a distillation plant of the multiple stage flash distillation type. The plant comprises a reinforced concrete shell which is divided into a large number of flash chambers and a heat supply chamber by means of separation walls. At least some of a bundle of continuous condensation tubes of plastic extend throughout all of the chambers. The tubes may be extruded in situ so that they directly move into position in the shell. The inlet and outlet manifolds for the tube bundle are defined by an end of the shell and an adjacent separation wall. The shell has preferably a plastic coating or consists of a polymer concrete. Preferably, the walls consist of or comprise plastic so that the bundle of plastic tubes may be sealed to apertures in the walls by gluing or welding.
Claims6
Distillation plant comprising an axially elongated tubular shaped shell, a plurality of generally vertically positioned horizontally spaced partitions extending transversely of the axis of said shell and dividing the interior of said shell into a plurality of serially arranged vaporizing chambers, a bundle of condenstion tubes extending through said vaporizing chambers and passing through said partitions between adjacent said vaporizing chambers, at least one of said partitions having an opening therethrough with said tube bundle passing through said opening, a bowl positioned in the opening in said partition and extending outwardly therefrom into each of the adjacent said chambers with the upper edge of said bowl located at least above the uppermost point of the opening through said partition, said tube bundle extending through and dipping into said bowl on both sides of said partition, and said bowl arranged to receive distillate to a level above the uppermost point of the opening in said partition so that a water lock is formed within said bowl for sealing the adjacent said chambers from one another.
