摘要
自80年代中期以来，气固并流下行床反应器以其接触时间短、接近平推流而成为气固流态化新的研究方向. 本文对目前下行床反应器出入口结构方面的研究现状进行了总结，包括下行床出入口结构设计、出入口形式对下行管流动混合行为的影响以及气固分离效率等. 在此基础上，探讨了下行床出入口结构及其性能之间的关系，并提出了下行出入口设计与放大的基本思路.
Since last ten years, the cocurrent downflow reactor(downer) has become a hot topic in fluidization research. The structure of inlet and outlet of a downer is critical for realizing effective gas-solids contact in very short time. This paper summarizes the current research work about inlet and outlet, including design and structure, and effect on hydrodynamics and dispersion behavior in the downer. Based on this, the relation of structure and performance was discussed, design and scale-up criteria were suggested.
