摘　　要：本文叙述了一种适合于颗粒涂覆用的，具有特殊的多气体入口的喷动床。研究了这种喷动床在不同气流量和松装体积时的五种特征状态，给出了各种状态下的颗粒循环特点，并描述了在不同气流量和松装体积区间内出现不同喷动状态的相图。Here a kind of spouted bed with multi gas inlets for fuel particles’coating is described. Five spouting condition in the spouted bed were found.The characters of particles’ circulating in each condition were shown. The Phase diagram of the spouting conditions was studied.

关 键 词：喷动床 多气体入口 颗粒涂覆
