| 摘 要： | 研究了废铅酸蓄电池膏泥和板栅的直接低温熔炼过程,开发出一种能耗低和环境有好的处理废铅酸蓄电池新技术。在较低温度下,考察了氢氧化钠加入量、还原剂加入量和碳酸钠加入量对熔炼过程的影响。小型试验和中间低温熔炼试验均取得了较好的结果。在温度920℃、氢氧化钠加入量为理论量、还原剂加入量为膏泥量的6%的条件下,大型试验的铅直收率达91.48%,渣率和烟尘率分别为17.49%和4.19%。

| Abstract: | Direct low-temperature smelt process of battery paste and battery plates was studied and a new technology for treating spent lead battery was developed.The effects of dosage of sodium hydroxide,reductant and sodium carbonate on the smelt process were investigated.Good results of laboratary and pilot experiment were achieved.The results of the pilot experiment indicated that direct recovery of lead is up to 91.4%,and rate of slag and rate of dust are 17.5% and 4.18% respectively under the conditions of temperature 920 ℃,dosage of sodium hydroxide theoretical amount and dosage of reductant 6%. |
