摘要: 本文研究了在负压差条件下,立管移动床中的气体流动特性,没有气体通过时的理想料封状态,以及固体流动速率。根据三种物料四种规格的试验结果,得出了综合关系式;并讨论了移动床的气-固流动,提出合理选择与设计移动床料封高度的方法。

Abstract: The gas flow characteristics, the ideal sealing state without gas passing through and the solid flow rate in a vertical moving bed under negative pressure difference were studied in this paper. The correlated equations were obtained based upon the experimental results of three kinds and four standards of particle materials. A discussion was made about the gas-solid flow further and a method was suggested to select and design the sealing height in a moving bed reasonably.
