气液喷射反应器是一种高强度反应器,反应器内部液滴粒径大小和分布对反应收率和选择性具有决定性影响。本文建立了气液喷射反应器内液滴粒径分布测量实验装置,并利用面激光诱导荧光（PLIF）技术对气液喷射反应器内液滴粒径分布进行了研究,得到不同气液流率情况下的液滴粒径的分布规律,结果显示：液相流率不变时,随气相流率的增大,反应器内液滴平均粒径逐渐减小,分布范围变小;气相流率不变时,随液相流率的增大,液滴平均粒径逐渐减小,粒径分布趋于集中。

Gas-liquid jet reactor is a reactor with high intensity.The droplet size scale and distribution in the reactor have crucial effects on the yield and selectivity of reactions.In this paper,experimental equipment was established for measuring droplet size distribution in a gas-liquid jet reactor.The technique of PLIF（Planar laser induced florescence）was used to investigate the droplet size distribution in the jet reactor under different gas and liquid flow rates.The result shows：①In the case of constant liquid flow rate,the jet inside the mean droplet diameters decreases and the distribution of droplet diameters becomes narrower with the increasing of gas flow rate.②In the case of constant gas flow rate,the mean droplet diameters became smaller and the distribution range became narrower with the increasing of liquid flow rate.
