摘　　要：烧结烟气粉尘排放量大、成分复杂,现有烧结烟气除尘装置对微米级粒子的收集效率不高,如果后续不对其进行深度处理,会对大气污染产生影响。以烧结烟气粉尘为研究对象,对粉尘的成分、粒径进行分析,通过搭建云式雾化除尘实验台,利用相变团聚、化学团聚以及湍流团聚技术,实现多场协同技术对微细颗粒物的脱除。结果显示,相变团聚与化学团聚能够明显增大微细粉尘粒径,多场协同团聚对PM_(2.5)、PM_(10)的最佳去除效率分别为96.19%和84.03%。The sintering flue gas dust emission is large and the composition is complex,and the existing sintering flue gas dust removal device has low collection efficiency of micron-level particles,and if it is not advanced treatment in the future,it will have an impact on air pollution.Taking the sintered flue gas dust as the research object,the composition and particle size of the dust were analyzed,and the removal of fine particulate matter by multi-field collaborative technology was realized by building a cloud-type atomization dust removal test bench and using phase change agglomeration,chemical agglomeration and turbulent agglomeration technology.The results showed that phase change agglomeration and chemical agglomeration could significantly increase the particle size of fine dust,and the optimal removal efficiency of PM_(2.5) and PM_(10) by multi-field synergistic agglomeration was 96.19%and 84.03%respectively.
