动力波ZnO脱硫技术在铅锌冶炼尾气脱硫中的应用

Dyna Wave zinc oxide desulphurization technology for the exhaust gas desulphurization in lead and zinc smelting plant

介绍了动力波氧化锌脱硫技术在铅锌冶炼行业制酸尾气脱硫中的应用情况。该脱硫装置采用铅冶炼烟化炉产生的氧化锌浆液作为脱硫剂,使排放气体SO2质量浓度从2 g/m3降至200 mg/m3以内,确保制酸尾气达标排放。脱硫产生的硫酸锌用作炼锌原料不产生二次污染。针对运行中存在的问题,技术人员通过不断技术改造,优化工艺参数,基本予以解决,确保了装置平稳运行。

DynaWave zinc oxide desulphurization technology for the exhaust gas desulphurization in lead and zinc smelting plant is described. Zinc oxide slurry produced by lead-smelting furnace is used as a desulphurizer to make the concentration of SO2 gas emission reduce from 2 g/m^3 to less than 200 mg/m^3, thus ensuring tail gas upto emission standards. Zinc sulphate produced by desulphurization is used as raw material for zinc smelting with no secondary pollution. Technical staffs continuously transformed technology for solving the existing problems during the operation, optimized process parameters to ensure smooth operation of the devices.
