摘　　要：铜电解精炼过程中产生的阳极泥,其中贵金属和稀散金属可被提取,具有重要的经济价值。基于某冶炼企业铜阳极泥焙烧工艺存在的问题如预处理不充分、喂料不均匀、窑尾负压波动大、窑体易变形以及射流泵内压过高等,结合EMERSON-DeltaV DCS控制系统,提出了调整浓密压滤方式、增加DCS联锁控制阳极泥浆化槽的液位、阳极泥浆化槽与给料槽间的液位联锁、增设负压延时保护、改善加热系统的燃料使用和增设射流泵传感器等措施。改造后,提高了回转窑的铜阳极泥日处理能力,改善了作业环境,降低了能源消耗,减轻了工人的劳动强度,有效降低了生产成本,延长了设备使用寿命。The anode sludge produced during the copper electrolytic refining process,in which precious and rare metals can be extracted,has important economic value.Based on the problems existing in the copper anode sludge roasting process of a smelting enterprise,such as insufficient pretreatment,uneven feeding,large fluctuation of negative pressure at the end of the kiln,easy deformation of the kiln body,and excessive pressure in the jet pump,combined with the EMERSON-DeltaV DCS control system,optimization measures were proposed,such as adjusting the dense pressure filtration method,increasing DCS interlock control of the anode slime tank's liquid level,establishing liquid level interlock between the anode slime tank and the feed tank,adding negative pressure delay protection,improving fuel usage in the heating system,and adding vacuum pump sensors.After these improvements,the daily processing capacity of the rotary kiln for copper anode slime had been increased,the working environment had been improved,energy consumption had been reduced,the labor intensity of workers had been reduced,production costs had been effectively lowered,and equipment lifespan had been extended.
