摘　　要：催化裂化反应系统相关装备的开发需要满足“高-快协同”,即应实现流动-传递环境的“三高”[油气-催化剂(简称油-剂)高效接触、油-剂高效分离、催化剂高效汽提]与反应动力学所要求的“快”的相互协同。基于将单一非均匀流化区域分解-重构的方法,开发了新型预提升装备和汽提装备;将空气动力学理论用于多相流分析,形成了可调控多股受限射流-多相流的进料装备技术;通过强化有效切向速度,开发了全新理念的提升管出口油-剂快速分离装备。这些装备不仅具备优良的性能,还可实现催化裂化反应系统内两相流型的快速转捩,获得了广泛的工业应用。The development of equipment related to catalytic cracking reaction systems needs to satisfy the“high-quick synergy”principle,which requires mutual coordination between the“three highs”in the flow-transfer environment[high-efficiency oil-catalyst contact(referred to as oil-cat),high-efficiency oil-cat separation,and high-efficiency catalyst stripping]and the“quick”requirement dictated by reaction kinetics.Based on the method of decomposing and reconstructing single heterogeneous fluidization zones,novel pre-lifting equipment and stripping equipment have been developed.By applying aerodynamic theorem to multiphase flow analysis,feed injection equipment that can regulate multi-channel confined jet flow-multiphase flow has been developed.Through enhancing effective tangential velocity,a revolutionary oil-cat rapid separation equipment with innovative concepts has been created for riser outlets.These equipment configurations not only demonstrate excellent performance but also enable quick phase transition of two-phase flow patterns within catalytic cracking reaction systems,achieving extensive industrial applications.
