Abstract: |
A vapor compression distiller having a shell for enclosing a pair of heat exchange tube bundles each having one end connected to a steam chest and its other end connected to a condensate collecting chamber. A vapor compressor has its inlet connected to the shell and the outlet to one steam chest which is coupled to a second steam chest through a steam ejector for elevating the inlet pressure to the second heat exchange tube bundle. A half partition extends across the lower end of the vessel and between the wells to divide the lower portion of the vessel into two sections which are in communication across the upper end of the vessel. One well is connected to receive fresh feed liquid and the other includes a density sensor to discharge a portion of the concentrate to therein maintain a desired concentrate level and each well is connected to a spray nozzle manifold disposed in its respective shell section.

I claim:
1. A vapor compression distiller system including a vessel,
- heat exchange tube means disposed within said vessel and including first and second groups of heat exchange tubes, the tubes of each group including inlet and exit ends,
- said vessel including a liquid collector,
- liquid distributing means disposed in said vessel and connected to said liquid collector for circulating liquid from said liquid collector over said heat exchange tubes whereby a portion thereof is evaporated,
- said liquid collector being constructed and arranged for receiving unevaporated liquid from said liquid distributing means,
- feed liquid delivery means for delivering feed liquid to said system and discharge means for discharging concentrate from said liquid collector,
- vapor compression means connected to said vessel for receiving evaporated liquid and for delivering compressed vapor to the inlet ends of said first group of heat exchange tubes,
- steam ejector means connected to the exit ends of said first group of heat exchange tubes for receiving the uncondensed vapor and non-condensable gases therefrom, said steam ejector means also being connected to a high pressure steam source for elevating the pressure of said vapor, said steam ejector means also being connected to the inlet ends of said second group of heat exchange tubes for delivering vapor at an elevated pressure thereto.
