摘　　要：针对提高脱硫效率和石灰石利用率、提高产品品质和降低厂用电率等问题,从优化分级效率的角度探索提高石膏旋流器性能的方法.采用试验的方法,寻找石膏旋流器结构和工作参数对分级效率的影响规律.结果表明:较高的入口压力、适中的溢流管壁厚和内径、较大的溢流管插入深度以及选用渐缩式阿基米德螺旋线入口结构等因素对石膏旋流器的分级效率有积极效果.To improve the separation efficiency, limestone utilization and final product quality of a wet limestone gypsum FGD system, and reduce the auxiliary power consumption rate of the power plant, an expermiemtal study was performed for optimization of the separation performance of the gypsum hydro-cy- clone, by analyzing the influence of cyclone＇s structure and operating parameters on the separation efficien- cy. Results show that for improvement of separation efficiency of gypsum hydro cyclones, it is effective to adopt higher inlet pressure, moderate wall thickness and inside diameter of overflow pipe, higher insertion depth of overflow pipe, and tapered Archimedean helix inlet.
