摘　　要：为提高重力式液-液分离器的流场稳定情况,针对处理量为0.2 m^3的分离器,应用Fluent软件对入口构件(防冲挡板)后安装整流构件(折流板)进行数值模拟,并研究分析有无折流板对分离器内部流场特性的影响,对不同折流板尺寸的4种结构进行相对标准偏差和矢量图的分析.结果表明:折流板的安装对分离器内部稳流具有明显作用,能够稳定冲击防冲挡板后带来的紊乱流场.不同尺寸的折流板对稳流的效果明显不同,当折流板两板之间的距离h为200 mm时,稳流效果最好,能够抑制流场内部旋涡和反混现象.In order to improve the stable flow field environment of the gravity type liquid-liquid separator.With and without battle plate was simulated to value their influence on the flow field for the capacity of 0.2 m 3 separator.And then four conditions with different sizes are studied by value and vector drawings.Research results show that the installation of the battle plates has obvious effect to steady flow and can be stable disorder owe to the striking baffle flow field.The sizes of baffle plates effect on the steady flow is significantly different.When the h of distance between the two baffle plates for 200 mm,the flow is the most homogeneous and can reduce and suppress the flow eddy and re-circulation obviously.
