1、年产250万吨炼钢生铁的高炉炼铁车间工艺设计专业:冶金工程学生:杨鹏程指导老师:王启铭设计总说明本初设计年产250万吨生铁的高炉炼铁车间工艺,高炉有效容积为3500m3。在经过翻阅大量相关资料的基础上进行设计的。设计内容主要包括八大部分:矿焦槽系统设计、高炉本体设计、鼓风机选型设计、热风炉工艺计算设计、煤气除尘及净化系统设计、出铁厂设计、喷煤系统设计、除尘系统设计。焦槽、矿槽合并设置,烧结矿、球团矿、生矿分散筛分、分散称量,焦炭分散筛分、集中称量,设置小焦块回收系统;高炉炉顶采用无料钟炉顶设备,设置两个铁口,无渣口及32个风口;出铁厂风口平台平坦化,
2、配备泥泡、开口机等设备;采用四座内燃式热风炉,设计风温为1100℃,热风炉的燃烧为高炉煤气;采用重力除尘器对煤气进行粗除尘,采用干法布袋除尘设施净化煤气;炉渣处理采用冲水渣工艺,成品水渣渣采用胶带机外运;喷煤系统采用并列罐喷吹主管直接喷吹,输送和喷吹介质采用压缩空气。本设计特点是采用了精料入炉,提高了了原料入炉品位。煤气采用干法布袋除尘,节电、省水,同时能得到高质量的煤气。采用新型全底虑法水冲渣工艺,流程短,投资少,可靠安全。本设计附有三张图纸:高炉砌砖图、热风炉砌筑按图、高炉车间平面工艺布置图。关键词:高炉,热风炉,喷煤,除尘第59页Annualo
