采用 φ２０ ｍ ｍ 环隙式离心萃取器研究了不同操作条件对夹带量和传质级效率的影响。选取的体系是高效酚萃取剂 Ｑ Ｈ１——苯酚硝酸溶液。试验结果表明，当转速为 ２ ５００～４ ０００ｒ／ｍ ｉｎ，总流量在８５ ｍ Ｌ／ｍ ｉｎ 以下，流比（水相／有机相）从 １∶１～４∶１，环隙为 ２．５～５．５ ｍ ｍ 时，只要这些操作条件匹配得当，两相出口液中的夹带量低于 ０．３％ ，传质级效率高于９０％ 。
The effects of different operating conditions on entrainment and mass transfer efficiency were investigated using a φ20 m m annular gap centrifugal extractor. Selected system is efficient phenol extractant Q H 1 - phenol nitrate solution. The experimental results show that the flow rate (water / organic phase) is from 1: 1 to 4: 1 and the annulus gap is 2 when the rotational speed is 2 500 ~ 4 000 r / min and the total flow is below 85 m L / As long as these operating conditions are properly matched, the entrainment in the two-phase outlet liquid is less than 0.3% at 5-5.5 m m and the mass transfer efficiency is higher than 90%.
