摘　　要：建邦集团炼铁厂1号高炉86万风量机组配套的布袋除尘系统存在输灰压力不够、输灰管道容易堵管等问题,针对此情况,重新设计输灰管道走向,并对输灰控制系统进行优化。通过改变PLC程序,使4组输灰管道同时输灰变为单组循环输灰控制;通过wincc7.5组态软件实现对高炉矿槽除尘系统的实时监控,历史数据存储、分析和查询及故障报警等多项功能。实践表明,该系统可使除尘系统输灰畅通无阻,维护周期变长,对企业起到减员增效的效果。There are some problems in the bag dust removal system of 860000 air volume unit of No.1 blast furnace in Jianbang Group Ironmaking Plant,such as insufficient ash conveying pressure and easy pipe blockage of ash conveying pipeline.In view of this situation,the ash conveying pipeline direction is redesigned and the ash conveying control system is optimized.By changing the PLC program,the simultaneous ash conveying of four groups of ash conveying pipelines is changed into single group circulating ash conveying control.Via wincc7.5 configuration software,the real-time monitoring,historical data storage,analysis and query,fault alarm and other functions of blast furnace trough dust removal system are realized.The practice shows that the system can make the ash transportation of the dust removal system unimpeded and the maintenance cycle longer,which has the effect of reducing staff and increasing efficiency for enterprises.
