| 摘 要： | 分别以碳酸钠、碳酸氢铵作脱硫转化剂，采用正交试验设计，研究了废铅蓄电池湿法再生时铅膏的碳酸化脱硫转化工艺。研究表明，碳酸钠相对碳酸氢铵脱硫转化效率更高。碳酸钠作脱硫剂时，各因素对脱硫率的影响程度顺序为：转化剂浓度〉矿浆浓度〉反应时间〉反应温度；碳酸氢铵作脱硫剂时，各因素对脱硫率的影响程度顺序为：矿浆浓度〉转化剂浓度〉反应时间〉反应温度。在转化剂浓度1．79mol／L，反应温度80℃，反应时间60min，矿浆浓度10％的相同脱硫转化条件下，碳酸钠的脱硫转化率可达99．99％，碳酸氢铵的脱硫转化率达99．27％。

| Abstract: | Using sodium carbonate and ammonium bicarbonate as desulfurizing conversion agent respectively,the desulfurization of lead paste from waste lead-acid batteries is studied in this paper by orthogonal experimental design.The results showed that the sodium carbonate is more efficient in desulfurizing conversion agent than ammonium bicarbonate.When sodium carbonate is used as a desulfurizer,the influence of different facts on desulfurization rate weakened as the following order: conversion agent concentration>p... |
