摘要
在空气、水和固体玻璃或陶瓷球颗粒床层中,测定了两相并流时的压降和持液量。讨论了流体流率、颗粒粒度及材质对压降和持液量的影响,比较了大颗粒和小颗粒的特性,修正了前人的一些关联式。
The pressure drop and liquid hold-up are measured in a trickled bed with the system of air-watersolid spheric particles(glass or earamics) in which the gas and liquid are in cocurrent. The inflences of flow rate, particle sizes and materials on the pressure drop and liquid hold-up are discussed. Basedon making a comparision between the characteristics of small and large particles, some correlations presented by the previous authors are modified.
