Optimization of inlet structure of liquid-liquid impinging stream cyclone reactor for epoxidation of fatty acid methyl ester based on CFD
Based on the epoxidation of fatty acid methyl ester catalyzed by peroxyformic acid,a novel liquid-liquid impinging stream cyclone reactor was proposed.The cold mixing performance of fatty acid methyl ester and peroxyformic acid in the reactor was investigated using the Eulerian-Eulerian model and RSM turbulence model.Besides,the dispersion uniformity of the dispersed phase was used to quantify the mixing performance in the liquid-liquid impinging stream cyclone reactor.Moreover,the effects of the two-phase inlet angle,inlet rising angle and relative position of inlet on mixing efficiency were studied.The results showed that the two-phase liquid in the impinging stream contact cavity was gradually mixed evenly under the action of impinging stream.Characterized by dispersion uniformity,when the two-phase inlet angle was 60°,the inlet rising angle was 10° and the relative position of the inlet was 5mm,the mixing effect of the reactor was the best.
