烧结机尾布袋除尘器具有处理风量大，清灰效果好，除尘效率高，运行可靠，维护方便，占地面积小等特点，广泛应用于钢铁冶炼厂、建材、电力、化工、碳黑、冶金等行业的粉尘治理和物料回收。

　随着近两年钢铁行业和火电厂的大规模建设，对环保提出了新的挑战。钢铁行业是国家重要的基础产业，又是高能耗、高排放、增加环境负荷源头的行业。钢铁生产在其热加工过程中消耗大量的燃料和矿石，同时排放大量的空气污染物。1996年钢铁工业二氧化硫(SO2)排放量为97.8万t，占全国工业SO2排放量的7.5%，仅次于电力、煤气、热水的生产供应业和化工原料及化学制品制造业，居第3位。烧结工艺过程产生的SO2排放量约占钢铁企业年排放量40%～60%，控制烧结机生产过程O2的排放，是钢铁企业SO2污染控制的重点。随着烧结矿产量大幅度增加和烧结机的大型化发展，单机废气量和SO2排放量随之增大，控制烧结机烟气SO2污染势在必行。国外已投巨资对此进行治理，甚至关闭了烧结厂。目前我国在烧结烟气SO2脱除方面基本上还处于空白，仅有几个小型烧结厂上了脱硫除尘器设施，而以烧结矿为主要原料的炼铁生产又不允许大量关闭烧结厂。因此，对烧结烟气进行脱除处理是满足今后日益严格的环保要求的比较特殊选择。目前的关键是借鉴国外的先进经验，开发应用适合我国烧结特点的先进脱硫除尘设备工艺。

烧结机除尘器的工艺过程
　　该工艺的原理是利用干粉状的钙基脱硫剂，与密相干塔及布袋除尘器除下的大量循环灰一起进入加湿器内进行增湿消化，使混合灰的水分含量保持在3%到5%之间，加湿后的循环灰由塔上部进料口进入塔内，工艺流程。含水分的循环灰有极好的反应活性和流动性，与由塔上部进入的烟气发生反应。脱硫剂不断循环利用，脱硫效率可达95%。终脱硫副产物由灰仓溢流出循环系统，通过气力输送装置送入废料仓。
