在Φ９２ｍｍ的有机玻璃导向管充气喷动床反应器内，以玻璃珠为实验物料，以空气作流动介质，在导向管的管壁上开孔，考察导向管的开孔率对导向管充气喷动床的床层压降、最小喷动速度、最大允许充气速度以及颗粒在壁效应区下移速度的影响．结果表明：随开孔率的变化，其床层压降曲线仍呈峰值变化，而且开孔率增加，床层操作压降减小．开孔后最小喷动速度略有增加，而最大允许充气速度有所减小，但开孔率为１时的最小喷动速度和最大允许充气速度与实壁时几乎相同．质量流率相同时，随开孔率增加，颗粒的下移速度减小．表明在导向管的管壁上开孔或采用有孔的导向管，有助于调节和控制导向管充气喷动床内环形区颗粒的停留时间
Φ92mm plexiglass guide tube inflatable spray bed reactor with glass beads as experimental materials to air as the flow medium in the guide tube wall to open the hole to examine the opening of the guide tube of the pilot tube inflatable spray Bed pressure drop, minimum spouting velocity, maximum allowable aeration velocity and the effect of particles moving downward in the wall effect zone. The results show that with the change of porosity, the pressure drop curve of the bed shows a peak change, and the hole opening rate increases and the pressure drop of the bed decreases. The minimum jetting velocity increased slightly after opening, while the maximum allowable inflation velocity decreased. However, the minimum jetting velocity and the maximum allowable inflation velocity when the opening rate was 1 were almost the same as those of the real wall. When the mass flow rate is the same, the rate of downward movement of the particles decreases with increasing the porosity. Indicating that the opening of the tube wall of the guide tube or the use of a perforated guide tube helps to regulate and control the residence time of the annular zone particles in the guide tube inflation spouted bed
