摘　　要：本次研究是通过对烟化炉的给煤装置进行升级改造,实现科学、自动作业,达到降本增效的目的。在摒弃原有通过中间仓给煤经平衡风加压,变频螺旋给煤与风,一并送入烟化炉炉内。该设备没有给煤计量装置,全靠手动调整变频档位控制螺旋转速来给煤量。经常会出现塌煤、断煤、给煤不均匀等隐患,导致烟化炉煤耗居高不下,且系统不能安全稳定运行。经过对烟化炉给煤装置进行升级改造后,能够达到自动化程度高、精确入炉给煤计量、解决塌煤现象,并且降低劳动强度,维护生产的稳定运行。本次生产实践研究在节能降耗、降本增效上效果明显,经过一年的生产实践,烟化炉吨氧化锌煤耗从2019年的1850kg/t降低到2021年的1352kg/t,实现降本增效,提升企业的经济效益,完成年度生产效益任务。This study is to upgrade the coal feeding device of smoke furnace,realize scientific and automatic operation,and achieve the purpose of reducing cost and increasing efficiency.In abandoning the original coal through the middle bin by balance air pressure,frequency conversion spiral coal and wind,together into the smoke furnace furnace.The equipment has no coal feeding metering device,all rely on manual adjustment of frequency conversion gear control screw speed to feed coal.There are often hidden dangers such as coal collapse,coal breaking and uneven coal feeding,which lead to high coal consumption of smoke furnace,and the system can not operate safely and stably.After upgrading the coal feeding device of smoke furnace,it can achieve a high degree of automation,accurate coal feeding measurement,solve the phenomenon of coal collapse,and reduce labor intensity,and maintain the stable operation of production.This production practice research has obvious effect on energy saving and consumption reduction,cost reduction and efficiency increase.After one year of production practice,the ton zinc oxide coal consumption of fuming furnace has been reduced from 1850kg/t in 2019 to 1352kg/t in 2021,realizing cost reduction and efficiency increase,improving the economic benefit of the enterprise and completing the annual production efficiency task.
