DE-SALINATOR FOR BRACKISH -OR SALT-WATER

摘要

A de-salinator (10) for brackish or salt-water has a heat insulating shell (11) enclosed by end plates (12); a heat exchanger (22) in the bottom of the de-salinator (10) is heated by engine coolant from an engine (27); at least one condensor coil (19) in the upper portion of the de-salinator (10) is separated from the heater exchanger (22) by baffles (15); and is connected to manifolds (33), (34) which pass through one of the end plates (12); the at least one condensor coil (19) uses brackish or salt-water to cool the fresh vapour drawn off from condensate collection chamber (20) through outlet (21) from the de-salinator (10). Engine driven pump (37) draws the water through the condensor coil or coils (19) and operates an eductor (36) which generates a partial vacuum in the de-salinator (10) drawing off brine from the bottom of the de-salinator (10) and any excess water in the de-salinator (10). The level of water in the chamber (13) is maintained by drawing off a portion of the heated water passing through the condensor tubes (19). The condensate is drawn from the outlets (21) via an eductor (46) which is driven by a suction pump (45) connected to the fresh water tank (47).
