针对隔板塔中隔板两侧气体分配比难以调节的问题，提出了一种新型隔板塔气体调配装置。利用计算流体力学软件 STAR-CCM+对该装置的性能进行了模拟分析，并经实验研究对模拟结果进行验证；对不同塔径下升气槽个数进行了模拟研究。结果表明：该气体调配装置能够有效地调节气体在隔板两侧的分配，并且气体通过该装置后分布较均匀，成功实现了气相在隔板塔内的分配控制，实验结果和模型模拟值符合良好。

In order to resolve the problem of controling the vapour split in the divided wall column (DWC), a new vapour splitter was put forward. The study was carried out by using the computational fluid dynamics (CFD) software STAR-CCM+ withk-ε turbulence model and SIMPLE method. The split and the nonuniformity of the vapour were researched and compared against experimental data. The relationship between vapour tubes and internal diameter of the column was examined by simulations. Model results and experimental data obtained in this study have revealed that the device can accurately adjust the vapour split and achieve a uniform vapour distribution. The model results were in good agreement with experimental data.
