A Seawater Desalination System for Small Craft

摘要

A seawater desalination device for a small vessel of the present invention includes: a vessel engine; a first circulation pump; a first heat exchanger; a first vacuum chamber; a first vacuum pump; a second vacuum chamber; a second heat exchanger; a second circulation pump; a condenser; a second vacuum pump; a fresh water pump; a fresh water storage tank; a salinity measurement sensor; and a control unit. The seawater desalination device evaporates seawater to generate fresh water using exhaust gas generated from the vessel engine. The seawater desalination device may use waste heat that is wasted in the form of the exhaust gas of a vessel to easily obtain drinking water and fresh water. Thus, the crews of fishing boats or deep-sea fishing vessels do not need to worry about securing drinking water even when sailing for a long time, so that the crews may concentrate on fishing.
