Abstract

The MP-PIC CPFD method was used to numerically simulate the particle flow in a moving bed, and the change of particle outlet flow under different discharge slope of the moving bed was studied, so as to select the appropriate discharge slope of the moving bed. The results show that when the discharge slope is 45 degrees, compared with the discharge slope of 30 degrees, the outlet flow is more stable, and the mass flow of 60 degrees is larger. In the unloading process with a calculated time of 30s, the cumulative discharge quality of the moving bed with a 30 degree and 45 degree discharge slope is similar, while the discharge quality of the moving bed with a 60 degree discharge slope is 116% of that of the other two moving beds. It can be concluded that the discharge slope of the moving bed at 45 degrees can ensure the good flow uniformity of the moving bed and the good flow uniformity of the moving bed. Through the three-dimensional numerical simulation of the moving bed, the theoretical basis for the structural design of the moving bed is provided.
