摘　　要：金川公司广西防城港铜冶炼采用闪速熔炼+闪速吹炼工艺,烟气条件稳定且SO2浓度高(>30%),针对高浓度烟气制酸过程转化热量不平衡问题,研发了SO2烟气分流控温平衡转化及余热回收技术,提高了SO2转化率,通过净化与转化—干吸之间的"一拖二"匹配化技术提高了冶炼烟气治理的灵活性。Considering the double-flash copper smelting technology in Guangxi Fangchenggang Copper smelter of Jinchuan company, the off-gas is relatively stable and the SO2 concentration is over 30%. With the heat imbalance during metallurgical flue gases acid production, the distributary conversion of SO2 flue gas and heat recovery technology was developed. The application of this technology improved the conversion rate and the flexibility of metallurgical flue gases acid production by the matching between cleaning and dry absorption.
