摘　　要：自19世纪以来,浮选技术一直是选矿行业、选煤行业、废水处理行业的热点,本文阐述了微泡发生器的喉管在浮选中的作用,并对其做了深入的研究,在特定的操作参数下,通过改变喉管的直径,采用流体动力学软件FLUENT来分析其结构内部的速度曲线、紊动能云图,从而求得合适且较高性能的微泡发生器,同时数值仿真结果对指导实际的工业生产具有非常重要的参考价值。Since the nineteenth century,flotation technology has been the hotspot in mineral selection industry,coal industry and waste water treatment industry.This article elaborated the effect of the throat pipes of micro-bubble generator on flotation and studied it deeply.The FLUENT fluid dynamics software was introduced to analyze the velocity curve of the generator and kinetic energy of turbulent cloud of the internal framework in order to get an appropriate and better capability for micro-bubble by changing the diameter of throat pipes in a particular operating parameters.At the same time,numerical simulation results possess a significant referential value for supervising the practical industrial manufacture.
