The invention discloses a ship bubble drag reduction and energy saving device which comprises a gas generator, a gas storage chamber and a gas releaser, the gas storage chamber is connected with the gas generator through a gas liquid inlet pipeline and a first hollow pipe, the gas storage chamber is connected with the gas releaser through a gas guide pipe, and the gas releaser is arranged at the bottom of a ship; a water inlet and a gas conveying opening are formed in the gas liquid inlet pipeline, and the diameter of the gas liquid inlet pipeline is gradually reduced in the direction away from the gas storage chamber; a gas-liquid mixer is arranged in the gas storage chamber, and a one-way valve connected with an engine waste gas pipe is arranged on the gas-liquid mixing chamber. Water and air enter the gas-liquid mixer sequentially through the conveying pipe with the inlet area gradually reduced, the air is brought out at a high speed by means of rotation of the impeller in the gas-liquid mixer, and therefore a stable air layer is formed to wrap the bottom of the ship body, the advancing resistance of the ship can be obviously reduced, and the resistance reduction effect is good; and the generation efficiency of the bubble layer is improved to a certain extent, engine exhaust gas is utilized, energy consumption in ship navigation is reduced, and environment friendliness is achieved.

    本发明公开了一种船舶气泡减阻节能装置,包括气体发生器、储气室和气体释放器,储气室通过进气液管道、空心管一与气体发生器相连,储气室通过导气管与气体释放器相连,气体释放器设置在船舶底部;进气液管道上设置入水口、输气口,进气液管道的直径沿着远离储气室的方向逐渐变小;储气室内设置气液混合器,气液混合室上设置与发动机废气管相连的单向阀。本发明通过水和空气相继经过进口面积逐渐减小的输送管进入气液混合器,借助气液混合器中叶轮转动以较高速度带出空气,从而形成稳定气层包裹在船体底部,有利于显著减少船舶前进阻力,减阻效果好;在一定程度上提高气泡层生成效率,利用发动机废气,降低了船舶航行中能量的消耗,对环境友好。
