摘　　要：喷射环流反应器是一种新型的气液或气液固接触反应装置,其中的喷射器结构会对反应器性能产生重要影响。文章采用计算流体力学方法,建立了文丘里型喷射器的数学模型,分析了吸气室、喉部和扩散段等结构对喷射器吸气量的影响规律。模拟结果表明:吸气室直径和气相入口方式对吸气量影响不大;喷嘴与喉部之间距离越小,喉部长度越短,吸气量越高;扩散段扩散角度在2~4°之间时吸气量存在最大值。Jet loop reactor is a new type of gas-liquid or gas-liquid-solid contact reactor,in which the ejector structure has an important effect on the reactor performance.In this paper,the mathematical model of Venturi ejector is established by computational fluid dynamics method and the influence rules of inspiratory chamber,throat and diffusion section on inspiratory capacity is analyzed.The simulation results show that the suction chamber diameter and the gas inlet have little influence on the suction volume;the smaller distance between the nozzle and the throat and the shorter throat length may result in higher suction volume;and the maximum suction volume exists when the diffusion angle of diffusion section is between 2°and 4°.
