浅谈1080立方米高炉矿槽除尘设计及改造

Brief Discussion on the Design of 1080 Cubic Meter Blast Furnace Dust Removal Tank

文中以某公司高炉矿槽除尘改造实例,重点论述了矿槽各工序粉尘产生的机理、设计原则、治理方案及实施过程中控制要点。通过加强密封(封闭)、除尘管道优化、部分设备改造等手段,改善矿槽环境,同时采用阀门连锁控制等,大大减少诱导风(野风)进入系统,降低布袋除尘的负荷,达到节能通风除尘的目的。

Taking the dust removal transformation of blast furnace trough of a company as an example,this paper focuses on the dust generation mechanism,design principle,treatment scheme and control points in the implementation process of each process of trough.By means of strengthening sealing(sealing),optimization of dust removal pipeline and transformation of some equipment,the ore tank environment is improved.At the same time,valve interlocking control is adopted to greatly reduce the induced wind(wild wind)entering the system and reduce the load of bag dust removal,so as to achieve the purpose of energy-saving ventilation and dust removal.
