PURPOSE: A multi-stage fresh water generator for a marine vertical type is provided to improve a fresh water production capability per a unit time by installing multiple evaporators up and down vertically. CONSTITUTION: A multi-stage fresh water generator (200) for a marine vertical type comprises multiple evaporators for evaporating seawater (320). Multiple evaporators are comprised perpendicularly in one container, and implement a miniaturization of the fresh water generator and a minimum of an establishment area. Multiple evaporators manufacture a lot of fresh water (280) per a unit calorie. The seawater for an evaporation injected into the evaporator is injected into the evaporator of an upper part, and releases a steam. The seawater for the evaporation is flowed into a second evaporator (230) of a lower part along a fluid path by gravity, and prevents a heat loss to an outside. A temperature of the seawater is increased to a lower part of the evaporator of a multi-stage, and an evaporation generation rate of the steam increases. |
