Through changing the shape of impeller, the agitated flow fields of carboxylation axe of 8 cubic liquid-solid two-phase system is carried out and the solid concentration is simulated. The carboxylation axe is optimized from the view of hydromechanics. Using simulation optimization results in actual industrial production, the results show that the carboxylation axe after the simulation and optimization of computational fluid dynamics (CFD) can improve the reactor of fluid flow inside, and then to influence the reaction, make the raw material conversion rate increased 5.6%.
