Abstract： There are scarce reports on the separation performance of discontinuous multi-cone cyclones.This paper presents a combined tricone cyclone structure.First，anumerical simulation was conducted for single factor analysis on the main structure，soas to identifythe influence ofeach factor on the separation eficiency.Second， based on the Placket-Burmann test，the influence weight of each factor was determined，and three important factors were selected.Third，combined with the steepest climbing test and response surface design，the three factors were optimized，and thefiting equations between diferent factors and overallseparation eficiency were obtained. Finall，the interaction between pairwisefactors was analyzed to explore their influenceon theoverallseparation eficiency.The results show that the optimal parameter combination is as follws：main diameter of 76.354 mm， upper cone length of 80mm ，and underflow opening diameter of 18.495 mm，corresponding to a gas separation efficiencyof 96.697% ，asolid separation efficiency of 86. 983% ，andan overall separation efficiency of 94.258% . The conclusions provide a theoretical reference for the research of separation performance of multi

cone cyclones.

在油田生产过程中，高效脱气与除砂是提高生产效率的关键手段之一。因此，气-液-固三相分离技术作为解决方案，已成为研究与应用的焦点。旋流器作为一种能够迅速且高效分离不相溶多介质的设备[1-2]，已广泛应用于多个分离提纯领域[3-4]。近年来，旋流器的结构优化研究取得了重要进展，推动了其技术的发展与应用[5-6]。

魏可峰等研究了下锥角对单锥旋流器分离性能的影响，发现在操作条件不变的工况下，增大锥角会增加压力梯度，使旋流器能耗增加，同时也会增加分离粒度，但分级效率降低，甚至出现“短路”现象。王月文「8研究了双锥旋流器结构参数对分离性能的影响，结果表明，大锥段锥角对旋流分离器的分离性能具有较大影响。刘培坤等[9]、S.SCHUTZ等[10]和YANGQ.等[1]将单锥旋流器与连续双锥旋流器的分离性能进行了对比，研究发现，双锥角旋流器相比于单锥旋流器具有更好的分离效果。马佳伟等对三锥角水介质旋流器的锥体结构进行了正交试验研究，结果表明，三段锥体对旋流器的分离性能皆有不同程度的影响，且影响程度依次为三段锥体、二段锥体、一段锥体。有学者提出内置倒锥式旋流器结构，武海平[13]设计了2种不同类型的倒锥式旋流器，经研究发现，带有集液孔的倒锥式旋流器相比于内嵌圆筒式倒锥旋流器具有更好的分离性能。

尽管众多学者对不同的锥体结构进行了深人探讨，但关于具有多个不同锥角组合的旋流器结构研究鲜有报道，特别是关于非连续多锥段旋流器的分离性能的分析。……
