昆钢4号!5号转炉(公称容量SOt)原设计年产钢66万吨, 转炉煤气全部燃烧放散,造成大量能源浪费并且污染了环境"随 着生产发展的需要,炼钢工艺不断改进,现两座转炉年产钢已达 到132万吨,并具备了年产钢150万吨的潜力,原有烟气净化回 收系统已不能适应目前生产发展的需要"为了更好的保证安全生 产,回收利用转炉煤气,节约能源,降低成本,减少环境污染, 需对现有烟气净化回收系统进行全面改造"本项目结合昆钢这一 实际,对4号!5号转炉烟气净化回收系统进行技术改造"报告 主要从除尘的角度,对4号!5号转炉烟气净化回收系统,进行 了系统参数计算!主要设备选型计算!系统布置及主要除尘设备 的图纸绘制"同时,对改造工程相配套的其他设施也作了初步设 计描述,并进行了概算和效益分析" 本项目是昆钢三炼钢规划目标中的主要技术措施之一,符合 国家能源综合利用与环保治理政策"该项目实施后,能保证安全 生产,顺利回收转炉煤气,节约能源,可显著改善工作区劳动卫 生条件和厂区大气环境质量,具有一定的经济效益!显著的社会 效益和环境效益" 关键词:转炉烟气净化回收技术改造可行性研究昆明理工大学工程硕士学位报告 AbstraCt originallydesignedforanannualProduetioneaPaeityof660,000tons, No.4andNo.5eonvertersofKu心ingIron&SteelColnpany,份hieh洲na nominalvol姗eof50tonseaeh,aredisehargingburnedgastoairduring dailyoperation.Thisresultsinhugewasteofenergyandeausesserious environmentalPollution.CallingforfurtherdeveloPIDent,thesteel mak1ngProeesshasbeenimProvingeontinuously.Nowtheannuale8Paeity ofthesetwoeonvertershavereaehedl,320,000tonsandhaveaPotential toPlltoutl,500,000tonsProduetseaehyear.50theoldeonvertergas dedustingandreeyelingsystemeouldhardly.eettherequirementsfor produetivitydeveloPment.InordertoensuresaferoPerationandreeyele eonvertergas,saveenergy,1湃ereostsandredueeenviro咖entalilnPaet, it.5necessarytomaketeehniealmodifieationsfororiginaldedusting andreeyelingsystemsofeonvertergas.
