摘要
通过分析承钢钒钛矿烧结烟气特点,针对湿法脱硫工艺流程存在的问题,采取拆除全部旁路烟道、优化脱硫各系统运行参数、开展Ca/S摩尔比研究攻关、降低除雾器故障率、提高副产物石膏品质等措施,使烧结机与脱硫系统同步运行率达到了100%,Ca/S摩尔比降低0.18,出口烟气二氧化硫平均排放达标率提高了5.5个百分点。生产实践证明:石灰石-石膏湿法烟气脱硫工艺对钒钛矿烧结烟气具有较强的适应性和推广意义。
In order to address the problems occurred during the wet desulfurization process for sintering vanadium titanium bearing iron ore, some measures had been taken, such as dismounting all flue gas by- pass ducts, optimizing individual system operating parameters and Ca / S molar ratio, reducing the failure rate of mist eliminator, and improving the quality of gypsum byproduct, under which the synchronous operation rate between the sintering machine and desulfurization systems reached 100%, and Ca / S molar ratio decreased by 0.18, emissions compliance rate of sulfur dioxide in the outlet flue gas increased by 5.5%.Limestone-gypsum wet flue gas desulfurization has been proven a suitable technology for vanadium titanium bearing iron ore sintering process.
