摘　　要：铅电解高锑残极因含锑较高致使阳极泥结构致密、坚硬,采用现有常用的残极洗刷机组难以洗刷下来,目前只能采用人工铲泥方式。文章主要介绍了广西某有色公司研制的利用公司余热锅炉所产的余热蒸汽和电解工序高温烟气作为热源,采用高锑铅残极烘干回收阳极泥工艺和装置,以达到高锑残极烘干的阳极泥经敲打自动脱落回收。按年产5000 t锑金属计算,与人工铲泥回收阳极泥工艺相比,年可节约成本85万元。该工艺为国内首创,研究成果的应用,利于清洁生产,可以利用二次能源,降低能源消耗,提高阳极泥冶炼回收率,对环境更友好,成果应用前景广阔。Due to the high content of antimony in the anode mud of lead electrolysis,the structure of anode mud is dense and hard.It is difficult to wash down by using the existing commonly used anode residue washing machine.At present,only manual dredging method can be used.This paper mainly introduces the process and equipment of recovering anode slime by drying high antimony lead residue using waste heat steam produced by waste heat boiler and high temperature flue gas of electrolysis process as heat source developed by a non-ferrous metal company in Guangxi,in order to achieve high antimony residual pole drying anode mud by beating automatic stripping recovery.According to the annual output of 5000 tons of antimony metal calculation,compared with the artificial shovel mud recovery anode mud process,the annual cost savings of 850,000 yuan.The process is the first in China,and the application of the research results is beneficial to clean production,utilization of primary energy,reduction of energy consumption,improvement of recovery rate of anode slime smelting,more friendly to environment,and wide application prospect of the results.
