摘要

为了寻找烧结机头烟气中微细颗粒物超低排放的方法

实验采用圆线、芒刺电晕线和传统、开孔型收尘极板进行组合

构成多种极配结构。通过分析不同极配结构下的收集效率及粉尘粒径分布

研究了影响烧结烟气中微细颗粒物捕集效果的因素。结果表明:粉尘粒径分布、流场结构是影响除尘效果的重要因素;开孔型收尘极板改变了放电空间的气流分布

实现了对PM2.5、PM10等超微细粉尘的高效捕集。其中

芒刺-孔板极配结构的除尘效率可达99.00%

可使烧结机头除尘机组末级电场颗粒物的排放密度低至5 mg/m3以下

达到了超低排放。

Abstract

In order to find a method for ultra-low emission of fine particles in the flue gas of sintering machine head

two kinds of corona wires（circular linear electrode

barbed electrode） and collecting electrodes（traditional plate

perforated plate） were used to form a variety of electrodes configurations in the test. Moreover

we investigated the factors that affect the collecting effect of fine particles in sintering flue gas through analyzing the dust collection efficiency and particle size distribution of different electrodes configurations. The results reveal that the particle size distribution and flue field structure are the predominant factors of removal effect. The perforated collecting electrode changes the airflow distribution in the discharge space and achieves a high collection efficiency of fine particles（such as PM2.5 and PM10）. Among them

the dust collection efficiency of the configuration with barb-perforated plate is up to 99.00%

and the emission concentration of particulate matter of electrostatic precipitators for the sintering machine head can be lower than 5 mg/m3 in last grade

achieving an effectiveness of ultra-low emission.
