摘　　要：为提升惰性粒子流化床的生产效率,在传统平板直孔及改良的斜孔气分板研究的基础上,设计加工了一种具有波纹板面结构的新型气分板。以洗衣粉悬浮液为模型体系,通过实测干燥强度随进风速率、进风温度、惰性粒子直径、进料体积流量及惰性粒子静床高等参量的变化曲线,考察分析了该新型气分板的生产操作性能。结果发现：在相同的操作工况下,与装载斜孔气分板时相比,装载该新型波纹气分板时的设备操作压降增加了6%~10%,干燥强度指标提高了15%~30%,生产效率得到提高。To improve the operation efficiency of an inert particle fluidized bed,a novel gas distributor with a corrugated surface structure is designed and manufactured based on the research of the traditional flat distributor with a straight hole structure and the relevant modified distributor with a tilted hole structure.With the detergent suspension employed as a model system,the production operation performance of the novel distributor is investigated by testing the change curves of drying intensity with respect to gas intake rate,gas intake temperature,inert particle diameter,feed volume flow and static bed height of inert particles.The results show： under the same operation conditions,compared with loading the relevant modified distributor with tilted hole,the operation pressure drop of the equipment with the novel gas distributor is added by 6%~10%,while the drying intensity increases by about 15%~30%,and the operation efficiency is improved.
