Structural optimization of axial cyclone reactor for alkylation of ionic liquids
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.
