PURPOSE: A seawater desalination or evaporation concentrating method is provided to recycle evaporation heat to enable desalination by using significantly small amount of overall energy. CONSTITUTION: A seawater desalination or evaporation concentrating method generates condensation by pushing vapor generated in an evaporation tub into a condensation tub, which is filled with water and the upper part is mostly sealed. The vapor of the evaporation tub is pushed down from an upper part to a lower part. The condensation tub is heated with constant heat to increase the temperature of the condensation tub higher than the temperature of water being evaporated in the evaporation tub. The vapor generated in the evaporation tub is pushed into the water of the condensation tub by using a low pressure compressor to mix and condense the vapor with water, and the generated heat is delivered to the water evaporated in the evaporation tub. |
