摘要

摘要: 针对烧结厂环境电除尘器颗粒物排放不达标问题，采用新型多孔收尘极板可提升整体除尘性能，以实现烧结厂环境除尘超低排放。首先对工业电除尘器烧结灰分取样分析，并采用COMSOL Multiphysics对两种板形除尘区域内电场、流场对比研究，最后以灰分取样结果为依据，对除尘性能进行模拟预测。结果表明：传统电除尘器对烟气中粒径为0.01~10 μm粉尘捕集效率较低，各电场内捕集粉尘中含Fe及其氧化物达到50%以上，具有一定的再生价值，粉尘整体比电阻值较高，均为10¹² Ω·cm；多孔板平均收尘场强高于平板，极板因开孔降低了板表面附近电场风速，并减缓了板表面附近的二次扬尘效应；在66 kV外加电压条件下，采用多孔板电除尘器增加了对粒径为0.01~10 μm的颗粒物捕集效率，可有效提高末端电场捕集效率。该研究结果可为新型多孔板在烧结烟气颗粒物超低排放的应用中提供参考价值。

Abstract: Electrical precipitators in the sintering plants are facing with the excessive emission of particulate beyond the standard limit， and the new type of porous dust collecting plate can promote the overall dust removal performance， to achieve the ultra-low emissions of sintering plants. The article first conducted a sampling and analysis of sintering ash in industrial electrostatic precipitators， and then used COMSOL Multiphysics to study the electric field and flow field within the dust collection areas of two types of plate shapes. Finally， based on the ash sampling results， it simulated and predicted the dust collection performance. The dust removal performance of the new porous plate electric dust collector was verified by practical engineering cases. The results showed that the collection efficiency of the electrostatic dust precipitator in the flue gas was low when the dust was in the range of 0.01 to 10 μm. The collected dust contained more than 50% Fe and its oxide， which had a certain regeneration value. The overall specific resistance of the dust was about 10¹² Ω·cm.The average dust-collecting field strength of a porous plate was higher than that of a flat plate. The opening of the plate reduced the wind speed of the electric field near the plate surface and slowed down the secondary dust lifting effect near the plate surface. Under the condition of 66 kV external voltage， the collection efficiency of particulate matter in the range of 0.01~10 μm was increased by using a porous plate electrostatic precipitator， which can effectively improve the efficiency of electric field capture at the end. The results can provide reference values for the application of new porous plates in the ultra-low emission of sintering flue gas particles.
