摘　　要：炼油工艺原料的重质化,劣质化越来越严重,人们对环境的保护意识增强,对轻质油品质量的要求提高,而环流反应器因具有结构简单、操作方便、能耗低、传质及传热效果好等特点受到越来越多的关注。研究了有分离器带翅片倒流筒的环流反应器气含率。实验在室温、压力0.2 MPa、水-空气两相物系的实验条件下,以有分离器带翅片导流筒的环流反应器(高为1 370 mm、直径为100 mm)为主要研究对象。实验研究了表观气速、轴向高度、底部间隙、顶部间隙、翅片导流筒以及气液分离器与上升区局部气含率和整体平均气含率的关系。Raw materials for refining process are poorer and poorer,while people＇s awareness of environment protection is enhancing,the quality requirements of light oil are higher and higher,so the circulation reactor has been paid more and more attention because of its simple structure,convenient operation,low energy consumption,good mass transfer and heat transfer effect.In this experiment,the gas flow rate of the circulating reactor（its height 1 370 mm,diameter 100 mm） with finned fins was deeply studied under room temperature and 0.2 MPa pressure in air-water two-phase system.The relationship between superficial gas velocity,axial height,bottom gap,top gap,the finned draft tube,gas-liquid separator and the local gas holdup in riser,overall average gas holdup was studied.
