본 발명은 컴팩트하고 높은 조수 효율을 실현하는 선박용의 진공막 증류식 조수 장치를 제공한다. 선박용의 진공막 증류식 조수 장치(1)는, 선박에 취입된 해수를 가열하는 가열 장치(10)와, 가열 장치(10)로 가열된 해수가 흐르는 가열 해수 통액부(20)와, 진공부(21)와, 가열 해수 통액부(20)와 진공부(21)를 이격시키는 소수성 다공질막(22)과, 가열 해수 통액부(20)의 가열된 해수로부터 소수성 다공질막(22)을 통하여 진공부(21)에 유입된 증기를 냉각시켜 응축시키는 냉각부(23)를 구비한 진공 증류 모듈(11)과, 진공부(21)를 감압하는 감압 수단인 물 이젝터(61)를 갖고 있다. 가열 장치(10)는, 해수를 선박의 열원의 열에 의해 가열하고 있다. 물 이젝터(61)는, 진공부(21)를, 가열 해수 통액부(20)의 해수 온도에서의 물의 포화 증기압 이하, 0.1 atm 이상의 압력으로 감압한다.

    Provided is a vacuum membrane distillation desalination device that is for a ship, is compact, and achieves high desalination efficiency. The vacuum membrane distillation desalination device (1) for a ship has: a vacuum distillation module (11) provided with a heating device (10), which heats seawater taken into the ship, a heated seawater duct (20), through which the seawater heated by the heating device (10) flows, a vacuum unit (21), a hydrophobic porous membrane (22), which separates the heated seawater duct (20) and the vacuum unit (21), and a cooling unit (23) which cools and condenses the vapor flowing into the vacuum unit (21) through the hydrophobic porous membrane (22) from the heated seawater of the heated seawater duct (20); and a water ejector (61) that is a decompression means that decompresses the vacuum unit (21). The heating device (10) heats seawater by means of heat from a heat source of the ship. The water ejector (61) decompresses the vacuum unit (21) to a pressure between the maximum vapor tension of water at the seawater temperature of the heated seawater duct (20) and 0.1 atm, inclusive.
