锯齿边窄条阀塔板流体力学和传质性能实验研究 总被引:3,自引:1,他引:2
详细分析了锯齿边窄条阀的锯齿边对传质性能的影响和锯齿边窄条阀的结构特点。在1000 mm×350 mm规格的实验塔中,以典型的水-空气冷模实验系统,对锯齿边窄条阀STV75塔盘和F1圆形浮阀塔盘进行了对比实验,测定了多种气液负荷下的压降、雾沫夹带、泄漏量等流体力学性能。利用氧解吸法,测定了塔板传质效率。实验结果和工业应用表明,在相同条件下,锯齿边窄条浮阀塔板比F1圆形浮阀塔板的板效率提高10%—20%、板压降降低100 Pa以上,雾沫夹带与泄漏与F1阀相当,是一种综合性能优良的新型浮阀。 相似文献

The hydrodynamic performance of a novel SiC foam column tray (SFCT), made of thin slices of SiC foam material with a high specific surface area, is investigated. The performance parameters include pressure drop, entrainment, weeping, and clear liquid height. The tests are carried out with an air‐water system under atmospheric pressure. The mass transfer efficiency of the new SiC foam column tray is studied in a stainless‐steel plate column. The results provide some important parameters for the development of this innovative SiC foam tray. 相似文献

新型固定阀塔板的流体力学和传质性能研究 总被引:4,自引:1,他引:4
提供了一种阀盖两侧具有向下弯曲折边的新型固定阀。在内径为500mm的有机玻璃塔内,以空气水为物系,研究了其流体力学性能;在内径为300mm的不锈钢塔内,以乙醇水为物系,常压全回流情况下,研究了其传质性能。研究结果表明:新型固定阀塔板的板压降略高于筛孔塔板,比F1 浮阀塔板小得多,雾沫夹带量小,雾沫夹带液泛点阀(筛)孔动能因子均比筛孔塔板、F1 浮阀塔板大,漏液量较小,漏液点阀(筛)孔动能因子比筛孔塔板低,比F1 浮阀塔板高,传质效率与F1 浮阀塔板相当。 相似文献

Column setup has been widely utilized in the petroleum and chemistry industries. However, with the fast progress of industries and the increasingly serious energy shortage, designing a new column setup with better performance and higher capacity becomes more urgent. In order to improve column's capacity and expand operating condition, a new type of column tray named novel vertical spray packing (NVSP) tray was designed and experimented. The performances of the novel tray, including pressure drop, weeping, entrainment and tray efficiency, were tested in a plexiglass column. In addition, performances of the novel tray were compared with that of the sieve tray and the Glitsch V1 valve tray. Based on the experiment data, the mathematical correlations of pressure drop, weeping and entrainment for the novel tray were established by regression analysis method. A fundamental model of dry pressure drop of the novel tray was promoted at the form of sum mode. The results indicate that the novel tray has wider operating condition and better performance. 相似文献
