铅锌冶炼烟气三氧化硫的分布及污酸减量化研究

Study on the distribution of sulphur trioxide and the reduction of spent sulphuric acid in lead-zinc smelting off-gas

主要从铅锌冶炼企业生产线各流程段烟气采集点中三氧化硫含量进行追踪测试,并对测试结果进行分析,从而得到三氧化硫流向,为铅锌冶炼企业控制回收硫提出了相应的建议。

The sulphur trioxide contentsinthe flue gasesat the collection points of the lead-zinc smelting companies various production sections were tracked and monitored.The test results were analyzed to obtain information about the input and output streams of sulphur trioxide in the process.Recommendations on how to control sulphur recovery were provided for the lead and zinc smelting companies.
