| 摘 要： | 在1 600 mm×220 mm矩形塔冷模装置上利用空气和水进行冷模试验，研究NS倾斜长条立体复合塔板的干板压降、湿板压降、雾沫夹带、泄漏等流体力学特性，并与F1浮阀塔板进行对比。结果表明，开孔为文丘里式、装有规整填料的NS-3倾斜长条复合塔板的干板压降和湿板压降比F1浮阀塔板低30%～35%，操作弹性比F1浮阀塔板提高近1倍，处理能力比F1浮阀塔板提高近1.7倍。

| Abstract: | The research of NS stereo composite trays of tilt strip (SCTTS）was introduced in this paper. Cold model experiments using air-water system were carried out in a 1 600 mm×220 mm rectangular column to investigate the hydrodynamic characteristics of NS SCTTS including pressure drop, entrainment and weeping. As compared with F1 float valve trays, the pressure drop of NS SCTTS was 30%~35% lower, the operation flexibility was doubled and throughput increased. |
