Effect of Rotation-starting Speed on Separation Characteristics of Hydrocyclones
A DN 50 axial hydrocyclone was employed to separate alkylation products from catalysts.Through numerical simulations and experimental validation,the influence law of swirling velocity on the two-phase volume distribution of alkylation products and catalysts within the cyclone flow field was discussed,including the oil recovery rate.The results demonstrate that,the separation efficiency of the hydrocyclone is enhanced with increasing swirling velocity,and which shows a positive correlation between swirling velocity and axial velocity,tangential velocity and turbulence kinetic energy of the alkylation products;the intensified aggregation of the light phase at the core and the convergence of the heavy phase near the wall can elevate oil volume fraction and the separation efficiency becomes increased nonlinearly and surpasses 90%when the swirling velocity exceeds 14 m/s.The experimental result complies with the simulation data.
