摘　　要：引射器应用于湿法磷酸装置磷酸浓缩工段的低压乏汽回收,具有较好的性能。为了引射器设计的精细化,采用Fluent软件对引射器内流场进行数值模拟计算,以掌握引射器内流场情况等。介绍了引射器的建模过程,并对引射器内流体的压力、速度、温度等数值模拟结果进行了分析,为引射器精细化设计提供了可靠的理论依据。The ejector used in the recovery of low⁃pressure exhausted steam in the phosphoric acid concentration section of the wet⁃process phosphoric acid plant offers good performance.In order to achieve fine design of the ejector,Fluent software is used to conduct numerical simulation calculation for the flow field in the ejector to learn about the flow field state in the ejector.The modelling process for the ejector is outlined,and the numerical simulation re⁃sults including pressure,velocity and temperature of the fluid in the ejector are analyzed,which provides reliable theoretical basis for refining the design of the ejector.
