某炼钢厂2#转炉一次烟气塔-环隙工艺技改前后除尘效果分析

Dust Removal Effect Comparisonof "Tower-ring" Gap Process Reform on First Flue Gas of a Converter

某钢厂2#转炉一次烟气除尘系统由原来"两文"系统改为"塔-环隙"系统,经过比较研究两种除尘系统的运行效果得出:塔-环隙系统实现喉口自动调节,出口含尘浓度明显降低,煤气回收利用率基本持平。

The dust removalsystem of first flue gas of No. 2 converter in a steel - making plantchanged from the ＂Two Ventu- ri＂ to ＂Tower - ring＂ system. A comparative study on removal effectsbefore and after the technological reform show thatthe ＂Tower - ring＂ system realized automatic regulation of throat with lower dust concentration in the outlet and the gas recovery ratio remains flat.
