摘要(Abstract)：

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。
