摘要
以水-空气为介质,研究了开孔率为15%,25%,35%的筛孔型润德塔盘的流体力学性能.结果表明,筛孔型润德塔盘的压降、气含率随开孔率增大而减小,泛点气速和操作弹性随开孔率增大而增大.开孔率为35%的筛孔型润德塔盘的干板压降、总板压降及气含率均低于开孔率15%和25%的塔盘,而操作弹性大于15%和25%的塔盘.
The hydrodynamic performance of sieve runde tray with opening ratio of 15%, 25%, 35% was studied with water-air system as medium. The results showed that the pressure drop and the gas holdup of sieve runde tray decreases with the increase of the opening ratio. The flooding velocity and operating flexibility increases with the increase of the opening ratio. Dry pressure drop, total pressure drop and gas holdup of sieve runde type with the opening ratio of 35% were lower than that with opening ratio of 15% and 25%, and operating flexibility is greater than that with opening ratio 15% and 25%.
