application of heat pump to the evaporator to multiple expansions in order to increase the level of the water dissalare thermal

摘要

the invention consists in combining a heat pump with an evaporator for expanding multiple, as seen in the drawing, the water from dissalare.yeah preriscaldata since comes from other industrial processes, it is still rising its temperature condensing the distillate of the first stage of expansion, and is further heated.before going into the first stage of the evaporator, through the pump to calore.il rest apparatus and an ordinary evaporator with multiple expansions.
