1. From this work , a new way to improve the fluidization quality of the ultra - fine powders is found , and the studying result can supply as a basis of further investigation and be able to be used in the design of a spouted bed with a draft tube for the ultra - fine powders
   本研究为改善超细粉的流化质量提供了一种新的思路，研究成果为进一步四川大学硕士学位论文开展有关基础研究和开发超细粉导向管喷动床反应器提供了良好的基础。
2. 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。
3. 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
