摘要
昆钢第三炼钢厂转炉一次除尘设备过气量超过设计能力,结合实际,进行了除尘器喷头选型和改造,以提高其除尘效率,提高风机转速,减少炉口烟气外溢量。实施以后,除尘器(一文、二文)除尘效率明显提高,实现了放散烟囱达标排放,风机叶轮积灰少,停机清灰时间明显减少。
Wet and non-combustion method is applied to clean flue gas from converter in Kunming No.3 steel mill.The flue gas content from dust-collecting equipment exceeds the original design of the machine,and the dust collection efficiency cannot meet the requirement.Therefore,improvements have been finished to reform nozzle of the dust collection,and increase the dust collection efficiency and the running velocity of the draught fan,and decrease the loss of the flue gas from the converter.All the above measures improve dust collection efficiency greatly,and realize the discharge of the dust that will meet the national standard.
