An industrial multistage circulation stripper (MSCS) is simulated to improve its stripping efficiency. In its baffle region, an amount of vapor is easily to be gathered under the baffle and forms the vapor bypass near the walls. The comparison of the vapor flux at each row of holes indicates that the reason is an improper hole layout in the baffles. A method of hole layout to improve the vapor‐particles contact is built based on the Bernoulli equation. The enhanced baffles can decrease the average standard deviation from 0.1783 to 0.0056 and improve the stripping efficiency in the downer baffle region. The vapor distribution in the baffles perfecting the hole layout is sensitive to the superficial gas velocity but not to the mass flow rate of particles.

工业多级循环汽提塔中气固接触的优化

模拟了工业多级循环汽提塔（MSCS）以提高其汽提效率。在其挡板区域中，一定量的蒸汽易于聚集在挡板下方，并在壁附近形成蒸汽旁路。比较每排孔的蒸汽通量，表明原因是挡板中孔的布局不正确。基于伯努利方程，建立了一种改善汽-质接触的孔布局方法。增强的挡板可以将平均标准偏差从0.1783减小到0.0056，并提高下部挡板区域的剥离效率。挡板中的蒸汽分布完善了孔的布局，它对表观气体速度敏感，但对颗粒的质量流量不敏感。
