Study on performance of a new gas distributor for dividing wall column

提出了一种新型的隔板塔气体分配装置,运用计算流体力学(CFD)建立了三维模型,采用双欧拉均相多相流模型对此装置进行了模拟。同时,搭建了此装置的实验流程,将此装置对于隔板两侧气体分配的效果与实验数据进行对比,验证建立的CFD模型。结果表明,模型的模拟结果与实验结果吻合较好,此新型隔板塔气相分配装置能够调节隔板两侧的气相流量。

A new type of gas distributor for dividing wall column is proposed. A three-dimensional model is established by using computational fluid dynamics（ CFD） and the double Eulerian homogeneous multiphase flow model is used to simulate this gas distributor. At the same time,the experimental process of this distributor is set up. The effect of this distributor on the gas distribution on both sides of the partition is compared with the experimental data to verify the established CFD model. The results show that the simulation results of the model are in good agreement with the experimental results. This new type of gas distributor for dividing wall column can adjust the gaseous phase flow on both sides of the partition.
