摘　　要：分别以碳酸铵和碳酸氢铵作脱硫剂对废铅酸蓄电池铅膏脱硫工艺进行了研究,考察了反应时间、反应温度、脱硫剂与硫酸铅物质的量比、液固体积质量比等参数对脱硫率的影响,确定了最佳工艺条件。研究结果表明:以碳酸铵作脱硫剂时,在反应时间60min、反应温度50℃、反应物物质的量比1.2/1、液固体积质量比5/1条件下,脱硫率达95.22%;以碳酸氢铵作脱硫剂时,在反应时间70min、反应温度60℃、反应物物质的量比1.6/1、液固体积质量比5/1条件下,脱硫率达90.46%。Desulfurized of lead paste in waste lead-acid batteries was researched using(NH 4)2CO3 and NH 4HCO3,respectively.The effects of reaction time,temperature,the molar ratio of desulfurization agent to lead sulfate and the ratio of liquid volume-to-solid mass on desulfurization of lead paste were examined.The optimum reaction conditions were determined.The results show that the desulfurization rate can reach 95.22%under the conditions of reaction time of 60 min,temperature of 50℃,mole ratio of 1.2/1,and liquid volume-to-solid mass of 5/1,using(NH 4)2CO3 as desulfurizing agent.The desulfurization rate can reach 90.46%under the conditions of reaction time of 70 min,temperature of 60℃,mole ratio of 1.6/1,and liquid volume-to-solid mass of 5/1,using NH 4HCO3 as desulfurizing agent.
