对于粉碎机针刺毡除尘器布袋的磨损题目，咱们总结了以下几个方面供朋友们参考：

1、粉碎机针刺毡除尘器布袋所配套的除尘骨架焊接处有破洞或毛刺时，或因烟尘腐蚀而使外表变得毛糙，亦会加速针刺毡除尘滤袋的磨损。布袋与多孔板密封不严，也会形成布袋顶端反褶处磨损。

2、除尘器过高的过滤气速，会使初始粉尘层破碎，招致粉尘冲击布袋而形成针刺毡除尘滤袋过火磨损。烟气中含尘超准、小灰斗积灰过量，也会使布袋加速磨损。

3、毁掉：形成除尘器布袋的毁掉的原因，要紧是针刺毡除尘滤袋外表的初始层厚度不行，烟气的温度过高所至。要是除尘器 处置的烟气温度超越布袋的工作前提，轻易使针刺毡除尘滤袋强硬缩短，或熔化发生破洞。要是除尘器布袋初始层厚度不行，烟气中的火星流入、或粉尘发烧，也可能使针刺毡除尘滤袋烧出孔洞。形成针刺毡除尘滤袋毁掉要紧表现在在线新换的针刺毡除尘滤袋上。若在线换除尘器布袋后未进行预涂灰，高温烟气佩戴火星干脆触布袋，也易使针刺毡除尘滤袋遭到烧损。确保针刺毡除尘滤袋外表的初始层厚度，保证排烟温度不超温可以防范针刺毡除尘滤袋毁掉。

4、磨损：针刺毡除尘滤袋的磨损要紧发生在除尘器中心部位。其要紧原因是烟气漫衍不均，在单室中心部位流速过高，以致粉尘冲击除尘器布袋，磨损布袋；也使针刺毡除尘滤袋的织物纤维张力受损，轻易部分招致针刺毡除尘滤袋穿孔、应用周期过短。针对时常磨损的针刺毡除尘滤袋，咱们必要换成耐磨损的针刺毡除尘滤袋。

5、粉碎机针刺毡除尘器布袋与除尘骨架间的距离过小过大轻易形成布袋的磨损。布袋与龙骨的直径相差联系，太小时针刺毡除尘滤袋成果欠安；太大时布袋与龙骨的冲突力增大，会加速针刺毡除尘滤袋磨损。某些针刺毡除尘滤袋会随温度变更较大、并且有伸长的特性，必要咱们特别留意。针刺毡除尘滤袋是布袋除尘器的严重组成片面，针刺毡除尘滤袋相配于心脏，其余配件辅佐它获得清灰成果，当咱们发现除尘器的除尘成果不睬想的时候，不妨针刺毡除尘滤袋老化了。
