我厂与机械部十院共同研制的浮油收集装置于1980年投入使用。废油回收效果很好。浮油收集装置构造如右图。用三个浮桶使整个装置浮于水面上,当罩桶顶面略低于池中水面时,开动电动机带动叶轮旋转,将浮油和水吸入中心管,而后进入集油罩桶。由于罩桶横断面突然扩大,流速突然变小。由于油水的 I plant and the Ministry of Machinery Institute of the joint development of oil slick oil collection device put into use in 1980. Waste oil recovery works well. The oil skimmer is constructed as shown on the right. Use three floaters to float the whole device on the water surface. When the top of the cover barrel is slightly lower than the water surface in the pool, start the motor to rotate the impeller to suck the oil and water into the center tube and then enter the oil collector barrel. Due to the sudden enlargement of the cross-section of the shroud barrel, the flow rate suddenly becomes smaller. Because of oil and water
