Based on CFD technology, the present paper is aimed at using numerical simulation to analyze uniformity of air flow of downward inlet and external filtration style bag filter under different inlet air velocities. The simulation results show that the distribution of air flow in jet direction on both sides of the filter bags is higher under different inlet air velocities in bag filter. On condition of inlet air velocity is 5.8m/s, 6.9m/s, 8.1m/s, 9.3m/s respectively, the maximum relative deviation of filter bag flow distribution is 24.54%, 26.93%, 29.27%, 31.38%, as the velocity increases, the i...
