摘要
微孔注气式旋流器是旋流分离技术与气浮选技术的巧妙结合,利用气泡携带油滴,形成油气复合体,能有效去除粘度大、乳化程度严重等难分离的油。油气复合体具有比油滴更大的直径、更小的密度。通过对油气复合体的径向进行受力分析,得出其径向主要受离心力、浮力、斯托克斯阻力,进而得出了油气复合体的运动方程。并通过试验验证了微孔注气方式有利于提高旋流器的分离效率,且分离效率最高可达95.9%。这为油田采油污水的处理提供了更好的途经。
Micro-porous air-injection hydrocyclone combines with the techniques of cyclone separation and air flotation so as to make use of air bubble to carry oil drip and to form oil-air mixture. In this way, the oil with high viscosity and serious emulsification can be effectively removed. Compared with oil drip, oil-air mixture has larger diameter and lighter density. In this article, the mechanical a- nalysis for oil-gas mixture in radial direction was carried out. It was known that in this direction, oil-gas mixture is subjected to centrif- ugal force, floating force and Stokes resistance force. Then, the motion equation was derived. By experiment, the fact that i.t will bene- fit to the separation efficiency of cyclone to use micro-porous air-injection method and the efficiency may reach 95.5% has been proved. Thus, this method is better way in the treatment of waste water produced in oil field.
