废铅蓄电池火法冶炼的联合脱硫除铅工艺研究
Research on integrated technique of desulfurization and lead-removal in process of pyrometallurgy of spent lead battery
摘要
Abstract
Integrated technique of desulfurization and lead-removal were studied for treating lead mud and by-product from the process of pyrometallurgy of spent lead battery in the paper. The methods that the NaCO3 used in lead mud desulfuration, CaO used in fixing sulfur of liquid, and NaCI-FeCI3 system used in removed lead of fix-sulfur solid were adopted. The results show that the fix sulfur rate is 77.47%, and lead leaching rate is 99.14%.The integrated technique has a much better effect in comparison with separate technique. NaOH in the liquid after fixing sulfur can cut the amount of NaCO3, and can be recycled as water for fragmentation and gas desulfurizer. The lead leaching rate of lead-removal liquid is as much as 31%. In that case, the less NaCI-FeCI3, is needed in lead-removal. Dealing with a ton spent lead battery, SO2 can be reduced by 3.532 kg, and economic benefit was 374.376 yuan can be gained. Compared with separate technique, this technique can conserve energy, cut emission, and reduce the pollution with remarkable economic and environmental benefits.关键词
