袋式除塵器的腐蝕原因及防腐措施

發表時間:2019-12-25 17:11  來源:本站

腐蝕是造成除塵器損壞的常見原因之一,特別是布袋除塵器,因為煙氣中腐蝕性物質較多,在高溫環境下腐蝕效果較大,會造成除塵器的損壞。腐蝕的主要原因是水解、氧化、酸堿腐蝕。破壞的主要原因是水解和氧化,但酸腐蝕少,堿腐蝕更小。
 

除塵器內壁、噴淋管等內部部件嚴重腐蝕是長期威脅除塵器正常運行的又一常見故障。它使壁面逐漸變薄,強度降低,而且隨著時間的推移磨損更嚴重。噴淋管特別是管口的腐蝕,使口徑逐漸增大,形狀不規則,不僅增加了壓縮空氣的消耗,而且使同一噴淋管下的清洗效果失控,這是我們不希望的。

因此,為了防止袋式除塵器的腐蝕,直接有效的措施是改進工藝系統和操作方法,避免結露。讓我們來看看具體的原因和解決辦法!
