Title: Desalination plant for sea water - using vortex tube ice producers and diffusers above level of contents of high freezing tank towers
Inventor: HOHMANN HERBERT
IPC: C02F1/22
Filed: 1973-01-08
Abstract: A desalination plant for sea water to produce fresh water by freezing passes the growing ice crystals and the freezing brine without centrifugal treatment through a high-pressure zone at the bottom of 50-70m high towers. Vortex ice producers are arranged above the outflow level of freezing tanks. The inlet level of the supercooled soln. leaving the vortex ice producers for the outflow pipes is high enough above the outflow level to keep the downflow velocity higher than the upflow velocity of the ice particles. Capital costs are only one-tenth of a conventional desalination plant and the high pressure promotes the formation of ice crystals. The vortex action produces ice with radial structure without the need for centrifuges.
