摘　　要：以广西某碳素公司400 kt/a预焙阳极碳素焙烧系统烟气治理项目为研究对象,设计了两套焙烧烟气处理系统,采用“降温预处理+电捕焦+脱硫脱氟除尘一体化”工艺,系统投运后,烟气各污染物浓度均稳定达到烟气超低排放标准(二氧化硫≤35 mg/Nm^(3),颗粒物≤10 mg/Nm^(3),沥青烟≤20 mg/Nm^(3),氟化物≤3 mg/Nm^(3)),为炭素工业焙烧烟气治理提供了一种可靠的技术参考。Taking the 400kt/a pre-baked anode carbon roasting system of a carbon company in Guangxi as the research object,two sets of roasting flue gas treatment systems are designed,after the system is put into operation,the process of“Cooling Pretreatment+electric coke capture+desulphurization,defluorination and dedusting”is adopted,the concentration of all pollutants in flue gas reached the ultra-low emission standard(SO_(2)≤35 mg/Nm^(3),particulate matter≤10 mg/m^(3),asphalt fume≤20 mg/m^(3),fluoride≤3 mg/Nm^(3)),it provides a reliable technical reference for flue gas treatment of carbon industrial roasting.
