In this paper,the CFD(Computational Fluid Dynamics)method is used to simulate the gas-solid two-phase flow in four types of prill towers with different structures.The flow field distribution and particle phase volume fraction distribution of the original structure are compared with those of the three amplified structures.The amplified structure with better performance is determined,and the effects of the inlet pitch diameter of bisphenol A and the insertion length of nitrogen outlet pipe on the uniformity of particle distribution are obtained,which provides reference for the engineering scale-up design of prill tower.
