According to the water film drag reduction system and the ship, heat in waste gas generated by ship navigation is used for heating seawater, high-temperature seawater obtained through heating is released to the ship bottom, and a layer of hot seawater film is directly arranged on normal low-temperature seawater in the ship bottom and the ocean by means of the characteristics that the temperature of the seawater is increased and the viscosity is reduced; therefore, the purpose of reducing the sailing resistance of the ship is achieved, and the corrosion risk of high-temperature air bubbles generated by an air lubricating system to a ship bottom coating is also solved; meanwhile, the ship fresh water system is utilized, waste heat of combustion equipment such as a ship main engine, a generator, a GCU and a boiler is recycled, and the ship operation economical efficiency is improved.

    本发明公开了一种水膜减阻系统及船舶,本发明利用船舶航行产生的废气中的热量来加热海水,并将加热得到的高温海水释放到船底,利用海水温度升高、粘性降低的特点,在船底与海洋中的正常低温海水直接一层热海水膜,从而达到降低船舶航行阻力的目的,也解决了空气润滑系统产生的高温空气泡对船底涂层的腐蚀风险;同时利用船舶淡水系统,实现船舶主机、发电机、GCU及锅炉等燃烧设备的余热再利用,提高了船舶营运经济性。
