袋式除尘器的腐蚀原因及防腐措施

发表时间:2019-12-25 17:11  来源:本站

腐蚀是造成除尘器损坏的常见原因之一,特别是布袋除尘器,因为烟气中腐蚀性物质较多,在高温环境下腐蚀效果较大,会造成除尘器的损坏。腐蚀的主要原因是水解、氧化、酸碱腐蚀。破坏的主要原因是水解和氧化,但酸腐蚀少,碱腐蚀更小。
 

除尘器内壁、喷淋管等内部部件严重腐蚀是长期威胁除尘器正常运行的又一常见故障。它使壁面逐渐变薄,强度降低,而且随着时间的推移磨损更严重。喷淋管特别是管口的腐蚀,使口径逐渐增大,形状不规则,不仅增加了压缩空气的消耗,而且使同一喷淋管下的清洗效果失控,这是我们不希望的。
 

因此,为了防止袋式除尘器的腐蚀,直接有效的措施是改进工艺系统和操作方法,避免结露。让我们来看看具体的原因和解决办法!
