system for desalting seawater and continuously removing ice and method for desalting seawater

摘要

SYSTEM FOR DESALINIZING SEA WATER AND REMOVING ICE CONTINUOUSLY AND METHOD FOR DEALING SEA WATER. The invention relates to a desalination method and system utilizing ice crystallization technology that incorporates the use of compressed air energy as a source of freezing temperatures. When compressed air is released by a turboexpander, the cooled air is produced as a by-product, where the cooled air is introduced into a chamber in which a spray cloud of seawater droplets has been pre-cooled by heat exchange with the cold walls of the chamber, is then circulated and exposed to the cooled air within the chamber. The drops then rest at the bottom of the chamber, where they are deposited slightly above the eutectic temperature, to form a snow / ice slurry mixture. A mud removal mechanism is provided with a screw-type helical blade to continuously remove ice particles from the chamber.
