Abstract
PURPOSE: To prevent the heating surface from the scaling, by combining the multiple effect evaporator and the multistage flash evaporator, and by heating the seawater, being preheated through the condenser tube of the flash evaporator, to temperatures above the precipitation temperature of CaSO4 in order to precipitate CaSO4 in the seawater.
CONSTITUTION: The seawater, being pumped up through the pipe 101 by the seawater pump 94, is preheated by the condenser tubes 69, 68...61 of the multistage flash evaporator 5, and is introduced into the CaSO4 precipitation tank 70 through the pipe 107. Hereupon, the seawater is heated by the steam to be supplied from the pipe 203 up to temperatures above precipitation temperature, and then, is introduced into the flahsing chamber 51 through the pipe 108. This seawater including CaSO4 crystal is evaporated while falling down in each flashing chamber 51, 52...59, and also, is introduced into the effect evaporators 11W13 through the pipes 109, 112, 115, etc.; hereby, the sweet water is generated in each chamber.
