Abstract：Compared with the circular filter bag, the pleated filter bag can further increase the filter aera, reduce the size of the equipment under the same air volume. In order to improve the dust cleaning performance of the pleated filter bag, the impulse injection experimental system of the pleated filter bag was established. The effects of pulse-jet pressure, pulse width and pleated ratio on the distribution of peak pressure along the length direction of the pleated filter bag were investigated experimentally. The results show that with different pulse-jet parameters, the peak pressure on the side wall of the pleated filter bag gradually decreases along the length direction, and the peak pressure near the bottom of the filter bag increases slightly. The influence of pulse-jet pressure on peak wall pressure is significant, and the sidewall maximum pressure increased with the increase of pulse-jet pressure. Pulse width has no significant effect on the peak wall pressure, but the pleated ratio has a significant effect on the peak wall pressure. When the pulse-jet pressure is 0.4-0.6 MPa and the pulse width is 100-200 ms, the filter bag with pleated ratio of 0.71 has better deashing effect. The results of dynamic dust separation show that the dust removal is realized under the two mechanisms of high-speed pulsed air carry and filter bag expansion.
