摘　　要：为应对湍急海面溢油回收难度大问题,设计了自诱导漩涡收油器进行溢油收集,通过数值仿真计算对该设备入流角度和插入深度进行适当的调整和优化,找到最佳入流角度和插入深度组合,以达到最佳的分离效果和油相收集效率。通过比较相同时间内设备内部的油相体积剩余情况,得出在20°的入流角度和设备高度三分之一的吸油管插入深度的条件下,该设备能够保持较高的油相分离效率,抑制油水混合,减少油水界面的扩散并减少杂质的混入。在确定最佳结构后,通过改变入流速度来确定设备在不同水面环境下的除油效果。结果表明,入口流速越大,设备汇聚油相的性能更强,除油效果越好。整个收油过程在设备内部进行,不受外部环境影响,说明该设备能够克服复杂的水面环境来进行收油作业。To achieve the best separation effect and oil phase collection efficiency,a self-induced vortex oil collector was designed to collect residual oil from the turbulent sea.The inlet flow angle and suction pipe insertion depth of the device were adjusted and optimized via numerical simulation calculations.By comparing the volume of oil phase remaining inside the device in the same operation time,we concluded that at an inlet flow angle of 20°and a suction pipe insertion depth of h/3,the device could maintain a high oil phase separation efficiency,suppress oil-water mixing,and reduce oil-water interface diffusion and impurities.After determining the optimal structure,we analyzed the oil removal effect of the device in different water surface environments by changing its inlet flow velocity.The higher the inlet flow velocity,the higher the performance of the device for collecting the oil phase and better its oil removal effect.In addition,the entire oil collection process occurs inside the device without being affected by the external environment,suggesting that the device can collect oil from complex water surface environments.Moreover,the main body of the device has no moving parts,hence,it relies solely on the baffle to guide the swirl for collecting the oil phase.
