袋式除尘器的应用已有百余年的历史,其优点是除尘效率高(达以上),排放浓度可达到10mg/m3以下,且分级效率也很高,对2.5μm以下的微细颗粒物也有很好的捕集效率,因此广泛的应用。但袋式除尘器经过多年的运行也暴露出一些问题,如滤袋易损坏、结露、运行阻力高、清灰失灵、灰斗卸灰不畅等。造成袋式除尘器运行出现问题的因素有很多,除了除尘器自身因素外,操作、管理不当也是造成其在运行中出现问题的重要原因。本文对目前袋式除尘器在运行过程中经常出现的问题进行了分析讨论。

腐蚀是滤袋损坏的常见的原因之一,由于烟气中含有多种腐蚀性物质,且在高温环境下腐蚀作用大,从而会造成滤袋损坏。产生腐蚀的主要原因有水解、氧化、酸、碱腐蚀。其中主要以水解、氧化原因造成损坏较多,而酸腐蚀较少,碱腐蚀则少。
