摘要
概述了镁电解槽技术的发展和应用,通过四种槽型对比指出了国内无隔板镁电解槽阳极氯气普遍存在浓度偏低等问题,若将此阳极氯气直接用于沸腾氯化炉生产四氯化钛将会带来许多生产难题。为了解决氯循环这一课题,本文提出了阳极氯气的吸收-解吸过程,即选用精四氯化钛作为吸收剂,通过吸收-解吸法提浓氯气,通过讨论分析可以确认该法技术上切实可行;同时,对氯化炉淋洗尾气的处理也提出了笔者的看法。如果该法实现工业化生产,一方面能够实现镁电解连续安全生产,氯气浓度增浓,降低氯气液化成本,另一方面可以大大改善沸腾氯化炉生产工艺状况,保障其稳定生产,同时可以减少环境污染。
The application and development in magnesium electrolysis processing are reviewed. And it is pointed out that the concentration of anede's chlorine of baffleless magnesium electrolytic cell is somewhat lower. Using directly anede's chlorine of baffleless cell in order to produce tetrachloride titanium by fluidized bed chlorinator will lead to a lot of problems. For the purpose of solving ones, the article gives a feasible way to increase the concentration of anode's chlorine of bafflelass cell, namely, the absorption - desorption process of anede's chlorine by selecting refined tetrachloride titanium as electrolytic chlorine absorbent. And a few personal views on how to settle chlorination tail gas are put forward. The significance of this method for the industrialized application is that on the one hand, it can realize continuous safe production and raise the concentration of chlorine in order to abate the liquefaction cost; on the other hand, it helps to improve greatly production situation of fiuidized bed chlorinator and reduce environmental pollution.
