Computational fluid dynamics (CFD) is a comprehensive subject which combined modern hydromechanics, numerical mathematics with computer science [9].
The Fluent is a kind of CFD software that uses finite element method (FEM) to simulate incompressible and moderate compressible flow [10].

The results show that: (1)Using the sense organ’s symmetry characteristic, a half model is built first, which is convenient for modelling and observing the simulation results;(2) Gridding should be meshed more densely where fluid grads is large, which is helpful of saving simulation time and improving precision.
The FLOTRAN CFD analysis function of ANSYS program is chosen, because it is an advanced tool used to analysis the two and three dimensional flowing fields [2].

In this paper, the 2D numerical simulation research for bench-scale circular cross-section riser based on EMMS methods is carried out.
With the development of the computer technology, the CFD (Computational Fluid Dynamics) has developed rapidly, which provide low-cost and high efficient design method [5, 6].

According to the simulation result, this article has analyzed the influence of different distances between the air nozzle and the filtering bag and different injecting times on the dust-cleaning effect, and supplied theoretical basis to design the optimal pulse bag filter.
The simulation indicates that 200mm is the best distance
