通过对该模型的无因次分析，找到了影响固体循环速率的无因次数群，并由实验数据回归拟合得到了固体循环速率的定量关联式，它与实验结果符合较好，误差为29 。 - It was found that the ultra - fine powder can flow smoothly in a spouted bed with a draft tube under some sorts of design parameter and operating condition , thus a new effective method to improve fluidization quality of the ultra - fine powders is obtained ; at higher supplied gas velocity , an increase in the solid circulation rate is observed ; the extent of the distance between the nozzle and the draft tube inlet result in the promotion of the solid circulation rate ; the solid circulation rate increase with increasing the draft tube diameter or the bed mass ; the gas bypassing is nearly zero in the present work ; and the solid flow in the annulus is observed as a moving bed
结果表明：在一定的床层结构和操作条件下，超细粉可以在导向管喷动床中实现平稳流化，从而为改善超细粉的流化质量提供了一种有效的新方法；固体循环速率与喷动气流量、导向管直径、导向管底部与喷嘴出口间距以及床层装填量成正比；气体则基本上不存在“旁路”现象；环隙区中的颗粒流动表现为一移动床特征。 - Fluidized behaviors of ultra - fine powder caco3 of mean diameter 5 um in a spouted bed with a draft tube were investigated , studying the effects of geometry and operating parameters on the two - phase fluidized characters such as the initial spouted behavior , the solid circulation rate , the gas flow distribution in the spout and the annulus , and the solid flow in the annulus
