The invention relates to an environment-friendly ship propulsion system and a corresponding ship propulsion method. An eco-friendly ship propulsion system comprises a permeation chamber (1), a decompression unit (2) and a desalination unit, the permeation chamber (1) comprising a high salinity zone (11) and a low salinity zone (12) separated from each other by a permeable membrane (13). The pressure reduction unit (2) has at least one pressure-to-motion converter which is connected to the high-salinity zone (11) of the permeation chamber (1) via a high-pressure line (21). The desalination unit is adapted to produce, on the one hand, salt or at least high-salt water and, on the other hand, fresh water or at least low-salt water. The desalination unit is connected with the low-salinity area (12) of the permeation chamber (1) through a fresh water pipe, and a saline water source (14) is controllably connected with the high-salinity area (11) of the permeation chamber (1).
本发明涉及一种环保船舶推进系统及相应的船舶推进方法。一种环保船舶推进系统,包括渗透室(1),减压单元(2)和脱盐单元,渗透室(1)包括通过渗透膜(13)相互隔开的高盐度区(11)和低盐度区(12)。减压单元(2)具有至少一个压力‑运动转换器,该压力‑运动转换器经由高压管线(21)连接到渗透室(1)的高盐度区(11)。所述脱盐单元适于一方面产生盐或至少高盐的水,另一方面适于产生淡水或至少低盐度的水。淡水管将脱盐单元与渗透室(1)的低盐度区(12)连接,盐水源(14)与渗透室(1)的高盐度区(11)可控连接。
