【摘要】 针对工业化生产中，粗品碳酸锂通过碳化提纯的过程，分析碳化过程的变量，包括粗品碳酸锂浆料密度、粗品碳酸锂浆料流量、碳酸氢锂热析母液流量、碳酸氢锂热析母液密度和碳化反应温度，通过多变量分析和变量变换，将影响碳化过程的多变量转化为在某一碳化反应温度条件下，碳酸锂浆料流量与热析母液流量之间的单一变量的控制逻辑，设计了碳化过程自动化连续稳定的控制模式，实现了碳化工艺连续自动化的运行，提高了生产效率及产品质量的稳定性。更多还原

【Abstract】 Analyzed the variables of lithium carbonate carbonization for lithium carbonate purificationincluding crude lithium carbonate slurry density and flow,lithium hydrogen carbonate digestion mother liquor flow and density,and carbonation temperature.Transformed the multi-variables of carbonation process as a single variable between crude lithium carbonate slurry flow and lithium hydrogen carbonatedigestion mother liquor flow under a carbonation temperature through multi-variables analysis and variable transformation.Improved the production efficiency and the stability of product qualityby designing a process for controlling running of lithium carbonate carbonization continuously and automatically.更多还原
