Effects of Discrete Phase Entering Positions on Separation Performance of a Hydrocyclone
摘要
Abstract
A discrete phase model (DPM) was applied to simulate oil droplet trajectory when entering a liquid-liquid separation hydrocyclone at various inlet cross-section positions. Moving rules for oil droplets entering hydrocyclone through different positions were studied. Results show that oil droplets that entering hydrocyclone at 2~2.5 mm from upper cover plate can easily form short-out flow, lower cover flow and cyclic flow. When droplets enter hydrocyclone at 0~0.5 mm radially and 0~7.6 mm axially of lower right area, they generally escape via underflow, and others are trapped by overflow. It is possible to improve the performance of the hydrocyclone by reducing underflow escaping rates through controlling of the initial position of dispersed phase droplets. This method is verified by experimental results of hydrocyclone separation efficiency.关键词
