摘要
综述了塔板技术的发展现状。介绍了近年来出现的新型浮阀塔板、新型筛孔塔板、立体喷射型塔板、复合塔板以及针对特殊物系设计的塔板的原理和结构特点。这些新型塔板与原有塔板相比,具有压降低、雾沫夹带量少、处理能力大、操作范围广及塔板效率高等特点。展望了今后塔板技术的研究方向。
The present status of tray technology is reviewed focusing on the principle and structure characteristics of the latest float valve tray, novel screen opening tray, stereo-jet tray, compounded tray and tray designed for specific feed system. As compared with the conventional types of tray, these novel trays exhibited lower pressure drop, lower entrainment, higher throughput, more flexible in operation and higher plate efficiency. Finally, the future research and development of various trays are discussed.
