本文报导了φ200mm脉冲筛板萃取柱(以下简称萃取柱)在半工业试验中的运行情况。萃取柱运行了980小时,总计处理水相料液425立方米。连续运行的结果表明萃取柱的各项指标均达到或超过设计要求,证明了脉冲筛板柱在萃取分离镍、钴工业上应用的可行性。
This paper reports the operation of the φ200mm pulse sieve plate extraction column (hereinafter referred to as the extraction column) in the semi-industrial test. The extraction column was run for 980 hours, totaling 425 cubic meters of water phase feed. The results of continuous operation showed that all the indexes of the extraction column met or exceeded the design requirements, and proved the feasibility of pulsed sieve column in the industrial application of extraction and separation of nickel and cobalt.
