Abstract：In order to solve the problem of the segregationof coke size charging in large-scale CDQ equipment,a three-dimensional discrete element method(DEM) was used to analyze the effect of bell distributor on reducing coke size segregation. The results are as follows.The coke size segregation in diameter direction and circumference direction is obvious,and the degree of coke size segregation in the y-axis is larger than that in x-axis;the segregation degree of coke in CDQ can be improved by the different angle of the distributor,and the 60° distributor can reduce the segregation degree of coke in diameter direction and the circumferential direction of CDQ,which is beneficial to further control the distribution of gas.
