摘要
公司原篦冷机抗故障能力差,运行不稳定,现场巡检不便,故障查找较慢,料层控制稳定性差,漏料严重。通过将6列篦床改为9列篦床,调整现场触屏和中控双显示,开发料床温度检测系统控制料层,增加液压油流量压力自修正和前馈控制,优化算法,自动调整压力系统设定值,篦冷机运行稳定性显著提高,二次风温由1050℃提高至1152℃,出篦冷机熟料温度平均约为85℃,熟料生产电耗降至60kWh/t。
Considering the unsatisfactory conditions of our existing grate cooler,i.e.the poor failure resistance,unstable operation,inconvenience for on-site inspection,slow troubleshooting,low stability of clinker layer control and high leak volume,some improvements were made,including changing the 6-row grate bed to 9-row grate bed,adopting the touch screen at the site and the double display in the central control room,developing the clinker bed temperature detection system to control the clinker layers,adding hydraulic oil flow pressure self-correction and feed forward control,optimizing algorithms and adopting the automatic adjustment to the pressure system settings.After the improvements,the operation reliability of the grate cooler is significantly improved,the secondary air temperature increases from 1050℃to 1152℃,the average temperature of clinkers out of the grate cooler is about 85℃,and the power consumption for clinker production decreases to 60kWh/t.
