我厂电解镍钴的生产过程中,溶液净化除铁采用氯气作氧化剂。由于反应管道设计不合理,造成氯气利用率低,大量含氯尾气排空,污染了环境,影响职工健康,危害农业生产,又浪费了液氯。 在批林整风运动的推动下,为消除氯气危害,降低氯气消耗,在厂党总支的领导下,开展了群众性的技术革新,采用逆流填料反应塔进行除铁作业,获得成功并用于生产。经不断改进完善,终于实现了氧化除铁 I plant electrolysis of nickel and cobalt production process, the solution used to purify the iron chloride as oxidizer. Due to unreasonable reaction pipe design, resulting in low utilization rate of chlorine gas, a large amount of chlorine-containing tail gas is exhausted, polluting the environment, affecting the health of workers and endangering agricultural production, and wastes liquid chlorine. In order to eliminate the harm of chlorine and reduce the consumption of chlorine, under the leadership of the rectification campaign of forest protection, under the leadership of the general branch of the factory, mass technological innovations were carried out, the counter-current packed reaction tower was used for iron removal operations, and was successfully used for production . After continuous improvement and improvement, finally achieved the oxidation of iron
