| 摘 要： | 以空气和水为介质，对筛孔型润德塔盘的流体力学性能进行实验研究，通过冷模实验考察其固阀开孔率、F因子、喷淋密度对干板压降、总板压降、清液层高度、平均泡沫层高度、操作弹性的影响，并与传统筛孔穿流塔盘进行比较. 结果表明，在操作范围内，筛孔型润德塔盘的操作弹性比传统穿流筛孔塔盘平均提升34.15%，固阀开孔率为33.3%的筛孔型润德塔盘总板压降比传统筛孔穿流塔盘平均低72.38%，比固阀开孔率为50.0%和66.7%的塔盘的干板压降平均低88.8%和206.3%，最佳固阀开孔率为33.3%. 得到筛孔型润德塔盘干板压降关联式为pd=49.98F1.785.

| Abstract: | The hydraulic performance of sieve Runde tray was studied with water and air as working media, the effects of opening ratio of fixed valve, F factor and spray density on dry pressure drop, total pressure drop, clean liquid height, average foaming height and operating flexibility were examined in cold model experiments, and compared with conventional sieve dual flow tray under the same conditions. The results show that the operating flexibility of sieve Runde tray is 51.4% lager than that of conventional sieve dual flow tray on average in the experimental conditions. The total pressure drop under the opening ratio of fixed valves of sieve Runde tray at 33.3% is 72.38% lower than that of conventional sieve dual flow tray on average, and its dry pressure drop is 88.8% and 206.3% lower than that of the opening ratios of fixed valves at 50.0% and 66.7% on average. The optimal opening ratio of fixed valves is 33.3%. The correlations of experimental data is obtained for calculation of the dry pressure drop of the tray as pd=49.98F1.785. |
