摘  要:沸腾氯化因具有生产效率高、成本低、环境污染小、自动化程度高等优点,已成为四氯化钛生产的主流方式。结合双瑞万基钛业公司研究实际,主要讨论了沸腾氯化生产四氯化钛过程中除铝、除钒以及除去四氯化钛中固体颗粒杂质的工艺及研究进展,认为采用氯化炉多级旋风分离系统、离心分离系统及真空搅拌蒸发系统除去四氯化钛中固体颗粒杂质,有机物除钒,配合精四氯化钛中氧碳杂质在线检测技术精准除铝等多项技术措施并用,可以满足高品质四氯化钛的制备需求。并认为有机物除钒和四氯化钛中固体颗粒物绿色环保回收技术将成为四氯化钛制备的主流工艺。Boiling chlorination has become the mainstream production method of tetrachloride production due to its advantages of high production efficiency, low cost, little environmental pollution and high automation. Combined with the research practice in Sunrui Wanji titanium industry company, this paper mainly discussed the process of removing aluminum, vanadium and solid impurities in titanium tetrachloride during the process of boiling chlorination production. By combining the on-line detection technology of oxygen and carbon impurities in refined titanium tetrachloride to accurately remove aluminum, we independently developed and designed a chlorination furnace multi-cyclone separation system, titanium tetrachloride centrifugal separation system and vacuum stirring evaporation system to remove the solid particle impurities in titanium tetrachloride, which can meet the requirements of highquality titanium tetrachloride preparation. And it is believed that the vanadium removal by organic matter and the environmentally friendly recycling technology of solid particles in titanium tetrachloride will become the mainstream production technologies of titanium tetrachloride industry.
