Abstract
A water de-salination and ice slush producing system separates potable water and brine from sea water in a reverse osmosis apparatus. A chiller tube produces ice slush from the sea water mixed with waste brine. The chiller tube has an outer housing and a first cylindrical wall, defining a first cooling space together with the outer housing. A first cooling conduit is inside the first cooling space, for circulating a coolant to cool down the first cylindrical wall. A second cylindrical wall defines an ice generating space together with the first cylindrical wall. An inside of the second cylindrical wall defines a second cooling space having a second cooling conduit, wherein coolant enters the second cooling space via a coolant inlet, is cooled by the second cooling conduit having a refrigerant circulated inside from a refrigerant inlet to a refrigerant outlet, so that the coolant in the second cooling space cools the second cylindrical wall, the coolant then being circulated through the first cooling conduit to cool the first cylindrical wall. A scraper is rotatable inside the ice generating space, to remove fresh ice crystals from both an inner surface of the first cylindrical wall and an outer surface of the second cylindrical wall and transfer the ice crystals to an outlet.
