中文摘要: 针对熔盐氯化各工序中固含量偏高、波动大、控制困难的问题，对氯化工序全流程TiCl4固含量展开了调研。调查结果表明，淋洗罐内固含量偏高、冷凝工序温度控制偏高造成粗TiCl4固含量偏高和沉降过程效果不明显。针对调查结果，提出了熔盐氯化炉欠氯反应技术、收尘室和淋洗系统温度控制技术及沉降控制技术等技术措施，有效降低了淋洗罐和粗TiCl4中的固含量，使淋洗罐内的固含量稳定控制在200 g/L以内，平均值为133.62 g/L；粗TiCl4中的固含量控制在15 g/L以下，减小了固含物对氯化系统和成品的影响，为氯化系统的稳定运行提供了保障，为粗TiCl4精制的产能提高奠定了基础。
Abstract:In sight of the problems that high content, large fluctuation and uncontrollable of solid content, the solid content of TiCl4 in the whole process of chlorination was investigated. The results show that the high solid content in leaching tank and the high temperature during the cooling process lead to the high solid content in the raw TiCl4 and the settlement of solid is not obvious. Base on the results, several technologies are proposed, including insufficient chlorine technology in chlorination furnace, temperature control technology in dust collecting room and washing system and settlement control technology, the solid contents in raw TiCl4 and leaching tank are decreased effectively. The solid contents in leaching tank can be stable controlled within 200 g/L with an average of 133.62 g/L, the solid contents in raw TiCl4 is controlled within 15 g/L, the effect of solid on chlorination system and products is decreased and it provides a guarantee for the normal and stable operation of the chlorination system and lays a foundation for increaseproduction capacity of refiningcrude TiCl4.
