摘要：与圆形滤袋相比,褶皱滤袋可以增大过滤面积,相同处理风量下可减少设备占地尺寸。为了提高褶皱滤袋的清灰性能,搭建褶皱滤袋脉冲喷吹实验系统,实验研究脉冲压力、 脉冲宽度、 褶皱比对褶皱滤袋沿长度方向侧壁峰值压力分布规律的影响。结果表明:不同喷吹参数时,褶皱滤袋侧壁峰值压力沿长度方向逐渐减小,靠近滤袋底部峰值压力又略微增大;脉冲压力对侧壁峰值压力影响显著,侧壁峰值压力随着脉冲压力增加而增大;脉冲宽度对侧壁峰值压力影响不显著,褶皱比对侧壁峰值压力影响较显著,当脉冲压力为0.4～0.6 MPa、 脉冲宽度为100～200 ms时,褶皱比为0.71的滤袋清灰效果更好;粉尘动态脱离结果表明清灰是在高速脉冲气流携带和滤袋膨胀2种机制下共同实现的。

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.
