    • A gas-solids contactor modification is described which provides for starting or restarting the gas flow to the gas-solids contactor when it is filled with solid particles while preventing the solids from entering and blocking one or more gas inlets which have diameters greater than the solid particle diameters The apparatus modification comprises a gas plenum and one or more chambers within the gas plenum located between the contactor inlet and the gas inlet The wall of the chamber has multiple passageways therethrough that are smaller in diameter than the majority of the bed particles Gas feed to the plenum must pass through the passageways in the chamber walls before entering the contactor. In one embodiment the total open area of the passageways is at least as large as the cross-sectional area of the gas inlet and the inlet to the contactor
    • 描述了一种气固接触器修改方案,当气固接触器填充有固体颗粒时,其启动或重新启动气体流至气固接触器,同时防止固体进入并阻塞直径大于固体的一个或多个气体入口 粒径设备改进包括气体增压室和位于气体增压室内的位于接触器入口和气体入口之间的一个或多个腔室。腔室的壁具有多个直径小于大部分床层颗粒的通道。气体进料 在进入接触器之前必须通过室壁中的通道。 在一个实施例中,通道的总开口面积至少与气体入口和接触器入口的截面面积一样大
