基于正交试验的双锥旋流器结构设计及优化

摘要

During the oil field development,the release of oily sludge inevitably pollutes the environment.It applies orthogonal design and computational fluid dynamics simulation to build separating fine particles of dual cone hydro-cyclone model.According to analysis on the different experimental of solid-phase volume,oil-phase volume of underflow port and pressure fall of overflow port,it obtains the optimal structure.Based on these tests,it describes the optimal structure operating parameters,designs efficient hydro-cyclone handling of oil-bearing sludge.This design reduces the environmental pollution.%在油田开发过程中,含油污泥的排放不可避免会对环境造成污染.首先通过正交试验及计算流体力学等方法,模拟出可用于处理细颗粒污泥的旋流器结构.然后通过对不同试验组的固相体积分数分布云图、底流口油相体积分数分布以及溢流口压力降的综合分析,筛选出旋流分离单体的最优结构,并针对最优结构优化其操作参数.最终设计出高效的处理油田含油污泥的双锥旋流结构单体,以达到减少环境污染的目的.
