PURPOSE:To raise the transferred amount of heat by averaging thermal conductivity in cooling tube by providing flush room, condenser room, lapping tube, etc. at the fixed places of cooling tube bundle. CONSTITUTION:At the intermediate stage of a multistage flush type water-making apparatus, for example, the sea water coming into the flush room 4 through the orifice 3 is cooled to a temperature corresponding to the pressure of the stage and flush-evaporated there, and the water vapor is introduced through the demister 8 into the condenser room 6 and then flowed uniformly into the cooling tube bundle 7 for liquefaction. The uncondensed water vapor is flowed the hole 13 into the lapping tube 12 provided in parallel with holed cooling tube, introduced into the gas cooling room 11, passed through the cooling tube bundle 7 uniformly, and sent through the extracting tube 9 to the rear stage 2 for extraction. Consequently, the flow rate and amount of water vapor are made uniform and therefore thermal conductivity in cooling tubes becomes averaged, raising the efficiency of water-making apparatus. |
