摘要：

To operate a bag filter continuously, pulse-jet cleaning of dust particles from the filter medium is com-monly required, and the pulse-jet pressure significantly affects the filter performance. In this study, the accumulation structure of residual dust particles inside and on the surface of a filter medium at different pulse-jet pressures was investigated by constructing a simple model, and the influence of the dust structure on the filter performance was clarified. Using a simple model, we determined the effective ratio of filtration area beta, which represents the ratio of the filterable area to the total filtration area, the true resistance coefficient due to the primary dust layer zeta(p)' thinly deposited on the filter surface, and the true resistance coefficient inside the filter media itself zeta(f)'. The effective ratio of filtration area fi decreased with operation time for all pulse-jet pressures; however, it maintained a high value when the pulse-jet pres -sure was high. The validity of beta analyzed by the model was verified using two different methods, and the results showed good agreement, indicating that the model is effective in identifying real conditions. The true resistance coefficient due to the primary dust layer zeta(p)' decreased as the pulse-jet pressure increased; however, the true resistance coefficient inside the filter media itself zeta(f)' was the highest at 0.5 MPa. In addition, the dust collection efficiency was different at each pulse-jet pressure, which was considered to be caused by the difference in the dust particle accumulation structure.
