本技術涉及環境保護領域,尤其涉及一種高爐煤氣除塵器。
技術介紹
高爐煤氣為高爐煉鐵副產物,屬于有毒可燃性含塵氣體,通過全干法袋式除塵器過濾凈化后方可使用。隨著高爐煤氣全干法袋式除塵技術日趨成熟,大型高爐(3000m3以上)煤氣凈化也逐漸采用全干法袋式除塵器。因大型高爐煤氣量較大,如采用DMOOOmm,DN5000mm直徑的箱體,除塵器筒體數量就比較多,故障點較多,對于高爐安全生產造成隱患。因此采用大直徑箱體DN6000成為大勢所趨,如何做好大直徑箱體的氣流分布,對于大型高爐全干法袋式除塵系統的安全、穩定、高效的運行尤為重要。原有小直徑的除塵器筒體或者大筒體大部分采用除塵器直段底部進風的形式;導流裝置也未設置,這樣容易造成,氣流分布不均勻,局部濾袋過濾負荷過大;均流整流裝置也未設置,容易形成渦流,造成濾袋晃動,濾袋底部因摩擦而破損。 ...
