摘　　要：对现有堰式撇油器的原理和结构进行改进,使其具有油水分离功能:利用泵吸产生的负压将油水混合物快速吸入集油箱,进入箱内的油滴因为流动中获得的向上初速度和浮力的作用而迅速上浮分离。将分离出的纯油回收,水排出集油箱外。改进后的撇油器溢油回收的效率大幅提高。After the theory and structure being improved, the weir skimmer obtains the function of oil-water separation. Oil water mixture is inhaled into gathering box by negative pressure produced by suction of pump. With initial vertical velocity gained from fluxion, oil drops are driven to rise rapidly and accumulate at the top of the gathering box by buoyancy. Separated oil can be recovered and water is pumped out. Being improved, the recovery speed and efficiency of the weir skimmer are increased markedly.
