摘　　要：介绍了一种利用现有生产线增湿塔设备进行石灰湿法脱硫的技术改造方案。该方案可根据生料磨停机计划和SO2排放情况灵活开启,投资少,脱硫效果明显。改造后,生料磨停机时的二氧化硫排放由原来的189~225mg/m^3之间波动降至40~60mg/m^3之间波动,未再出现过超标现象。投入使用两年来,未对增湿塔产生不利影响。This paper introduces a technical transformation scheme of lime wet desulfurization using existing humidification tower equipment of production line.The revamp can be opened flexibly according to the shutdown plan of raw mill and SO2 emission,with less investment and obvious desulfurization effect.After the revamping,the sulfur dioxide emission of the raw mill decreased from 189~225mg/m^3 to 40~60mg/m^3,and there was no environmental failure phenomenon according to the standard.In the past two years,the tower has not been adversely affected by the wet desulfurization.
