Structural optimization of axial cyclone reactor for alkylation of ionic liquids
为了研究结构参数对离子液体烷基化用旋流反应器分离性能的影响,采用雷诺应力模型和Eulerian多相流模型研究不同结构参数对旋流反应器轻相收率、重相收率及综合效率的影响;同时结合响应面法分析结构参数对反应器分离性能影响的相互作用,确定最优的反应器结构.结果表明:锥段角度z增加,旋流反应器轻重两相分离效率均先增大后减小,在z=5°时,分离效率有最优值;溢流管插入深度l增加,旋流反应器两相分离效率先稳定不变后缓慢下降再趋于稳定,整体变化在10%以内;溢流管直径d对反应器分离效率的影响较小;依据响应面法分析得到结构参数对反应器分离效率的影响显著性顺序为:锥段角度z>溢流管插入深度l>溢流管直径d,同时得到旋流反应器最优结构为:z=5°,l=13 mm,d=13 mm;在该结构参数组合下,旋流反应器综合效率为82.28%,较优化前提高了17.19%.研究结果可为实现两相的充分分离提供更优结构.
To investigate the effect of structural parameters on the separation performance of the cyclone reactor for ionic liquid alkylation,the Reynolds stress model and Eulerian multiphase flow model were used to study the effects of different structural parameters on the separation efficiency of the two phases and comprehensive separation efficiency.Moreover,the response surface method was used to analyze the interaction of structural parameters on the effect of the separation performance and determine the optimal structure of the cyclone reactor.The results indicate that the separation performance of the cyclone reactor increases and then decreases with the increase of the cone angle z,and the highest separation performance appears at z=5°.The separation efficiency stabilizes first and then slowly declines and finally stabilizes with the increase of the overflow tube insertion depth l,and the overall change is within 10%.The overflow tube diameter d has little effect on the separation performance of the cyclone reactor.the order of significance of the effects of structural parameters obtained by the response surface method on the separation performance of the cyclone reactor is as follows:cone angle>overflow tube insertion depth>overflow tube diameter,and the optimal structure obtained is z=5°,l=13 mm,and d=13 mm;with this combination of structural parameters,the integrated efficiency of the cyclone reactor is 82.28%,which is 17.19%higher than that before optimization.The research results can provide a more optimal structure for achieving sufficient separation of the two phases.
