中文摘要: 提出了镍电解生产过程中粗碳酸镍制备工序优化改造的方案，并进行了论证试验。结果表明，现有镍电解生产工艺设备可以进行三方面改造，即改变反应槽镍液和碱液进液位置及流量分布；反应槽改为并联反应方式；碳酸镍制备工艺技术条件改为：停留时间5 h，pH 7.8?0.1，反应温度55 ℃。改造后的碳酸镍各项指标和产能可以达到工艺要求，工艺容易实现自动控制。
Abstract:The scheme of modification and optimization on preparation of crude nickel carbonate in nickel electrolysis was put forward, and the demonstration experiment was conducted. The results show that process equipment can be modified in three aspects including changing feeding location of nickel solution and alkali solution and their flow distribution, changing connection of reaction tank to parallel connection, and changing technical parameters of crude nickel carbonate preparation to retention time of 5 h, pH of 7.8?0.1, and temperature of 55℃. After the modification, the indexes and production capacity of crude nickel carbonate can meet process requirement, and auto-control is easy to be realized.
