| 摘 要： | 为了提高重力式分离器的性能,选取不同结构的整流和聚结构件,采用Fluent数值模拟软件对分离器内部流场进行三维数值模拟,通过对比速度场和浓度场分布,确定整流和聚结构件的性能.在长为1.8 m,内径为384 mm的重力式分离器内安装4种不同结构的聚结板,改变进口含油率和流量,测量颗粒的单位体积质量含油率,确定聚结板的分离性能.结果表明:在流量较大的时候,聚结板分离效果下降,表现出对粒径选择性的单一分离作用;聚结板的结构和材质对液滴的聚结沉降影响很大,应根据工况和处理条件进行合理选择.

| Abstract: | In order to increase the efficiency of gravity separator,different kinds of commutate and coalescence internals were chosen.Three-dimensional numerical simulation of flow field in separator was carried out by Fluent software.Comparing the velocity field and concentration field,the performances of the commutate and coalescence internals were obtained.Experiments on separation behaviors of 4 kinds of coalescence plates were carried out in a separator with diameter of 384 mm,length of 1.8 m.The separation beha... |
