摘要
以氯化法生产钛白粉的主要原料酸溶性钛渣中的水分为研究对象,对酸溶性钛渣的常规干燥特性及影响因素进行了研究。通过研究酸溶性钛渣在温度变化、样品质量变化、以及初始含水量变化的条件下,获得干燥过程中的水分迁移行为,从而揭示酸溶性钛渣干燥过程的基本规律,探明酸溶性钛渣内部的传质机理。通过实验研究和理论探讨,为干燥冶金、化工原料的工业化应用和推广提供实验依据和理论基础。
The research object of this paper is the water in the acid-soluble titanium slag,the main raw material for the production of chlorinated titanium dioxide.The conventional drying characteristics and influencing factors of acid-soluble titanium slag were investigated.By studying effects of temperature change,sample quality change,and initial water content change on the acid-soluble titanium slag,the water migration behavior during the drying process was obtained,thereby revealing the basic law of the acid-soluble titanium slag drying process,further proving the internal mass transfer mechanism of the titanium slag.Through experimental research and theoretical discussion,the study can provide the scientific basis for the industrial application and promotion of dry metallurgy and chemical raw materials.
