摘　　要：焦炉是焦化生产的主要设备,也是焦化厂生产过程中的最大污染源。原焦炉装煤过程产生大量烟尘,采用炉顶消烟除尘车除尘。消烟除尘车处理效果不理想,释放大量烟尘。针对捣固焦生产过程中焦炉在装煤过程产生的大量烟尘,采用拦焦车集尘罩导入消烟除尘车二者配合除尘,进行了2次改造。第2次改造后采用间距为500 mm,互相垂直的2组折流板结构,2组折流板底部各增加1组旋向相反的螺旋喷淋器,洗涤折流板,除尘效果良好,烟气排放达到并优于环保标准,烟尘排放量远低于国家标准,减排效果显著。Coke oven is the main equipment in coking process,its also the biggest pollution source in coking plant. The smoke prevention and dust control car was used to treat the flue dust generated in coal charging. While the treatment effects were not good. A dust collecting cover was adopted to enhance the dust removal effects. Installed two groups baffle plates which were vertical and the distance was 500 mm.Two groups of spiral sprinkles were fitted on the bottom of baffle plates separately. The baffle plates were washed by spiral sprinkler whose rotation direction was opposite. The smoke and dust was reduced significantly and the emission was far below the national standards.
