The Optimal Structure Parameters of Hydrocyclone with Dual Cone Based on Orthogonal Design
摘要: 油田勘探与开发过程中所产生的含油污泥的排放和处理一直是各大油田急待解决的问题，本文基于正交试验及计算流体力学模拟出适用于处理细颗粒污泥的双锥旋流器的单体结构。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，得到最优结构。并针对最优结构优化其操作参数。最终设计出用于高效处理油田含油污泥的旋流结构单体，其优化后的结构分离效率可以达到96.22%。
Abstract:
Emissions and processing of oil-bearing sludge generated during oil field exploration and produc-tion processes have been major problems to be solved. Based on orthogonal design and computa-tional fluid dynamics, dual-cone hydrocyclone monomer structure suitable for separating fine particles has been simulated. According to the analysis of solid-phase volume, oil-phase volume of underflow port and pressure fall of overflow port in different experimental groups, the optimal structure was found. Through these tests, the optimal structure operating parameters were found. Finally dual-cone hydrocyclone monomer structure was designed for high-efficient treatment of oil-bearing sludge. The optimal efficiency can reach 96.22%.
