Water desalting device

Abstract

Abstract PURPOSE:To improve desalting efficiency by providing a washing device which supplies washing water to the surface of a turning member and a collecting device which removes the water formed on the surface of the turning member. CONSTITUTION:A refrigerant is blown to the inside surface of the turning member 1 from refrigerant spraying pipes 10... of a cooling mechanism 7 to cool the member 1 to a prescribed temp. and the member 1 is rotated at a low speed by a driving mechanism 6. Pure water is sprayed from a spraying pipe 14 to the outside surface of the member 1 and the ice crystals to become seeds are formed on the outside surface of the member 1. Sea water is sprayed from the spraying pipes 17... on the outside surface of the member 1 on which the seed ice crystals are formed and the moisture in the sea water freezes with the seed ice crystals as nuclei, thus growing the ice crystals. The washing water is sprayed onto the surfaces of the ice crystals by which the salt component and sea water are washed away when the member 1 is further rotated.
