一、概述七号500吨吹氧平炉在生产过程中排出大量含尘烟气,污染环境,影响农作物生产,危害人民身体健康,因此在设计时采用了两台20米~3三电场电除尘器进行烟气净化,其流程见图1: 正常运转时:平炉—余热炉—电除尘器—引风机—小烟囱。电除尘器检修时:平炉—余热炉—锅炉引风机—大烟囱。电除尘器和余热炉同时检修时:平炉—大烟囱放散。该系统建成后,由于种种原因,一直未投产。1971年在七号吹氧平炉旁建了一座80吨氧气顶吹转炉,暂借给80吨转炉进行烟气净化。但因吹氧转炉烟气温度高,含湿
I. Overview The No.7 500-ton oxygen blowing hearth emits a large amount of dusty flue gas during the production process, polluting the environment and affecting the crop production, endanger the health of the people, so two 20m ~ 3 three electric field electrostatic precipitators Flue gas purification, the process shown in Figure 1: normal operation: open hearth - waste heat furnace - electrostatic precipitator - induced draft fan - a small chimney. ESP maintenance: open hearth - heat furnace - boiler induced draft fan - large chimney. ESP and heat recovery furnace at the same time overhaul: open hearth - a large chimney to disperse. After the completion of the system, due to various reasons, has not been put into production. In 1971, an 80-ton oxygen top-blown converter was built beside No.7 blowing oxygen furnace and was temporarily lent to 80-ton converter for flue gas purification. However, due to high temperature blowing oxygen converter flue gas, moisture
