摘　　要：在新建炼钢转炉上,较多应用干法除尘系统,相对传统湿法来说,系统设备较少,耗能相对较低,除尘效率达到10 mg/Nm^3以下,且运行成本大大降低。因此在现行炼钢转炉中,将湿法除尘系统改造为干法除尘系统。通过对比分析,干法除尘系统更为经济,充分证明了湿法改干法的必然性和趋势。The dry dust extraction system is more applied to the new-built converters than the wet dust extraction system,for comparing to the conventional wet dust extraction system,the dry dust extraction system has fewer devices and lower energy consumption,the collection efficiency reached below to 10 mg/Nm^3,and production costs decreased evidently,so the dry dust extraction system is applied to the current converters instead of the wet dust extraction system,further by contrast analyzing on the two systems,it concluded that the dry dust extraction system is more economical to prove enough the necessity and tendency of the innovation.
