建立了一直径为0.186m、高3m的内环流气升式反应器。通过电化学方法测得了反应器中的气含率和速度。本文以文(Ⅰ)所得气升式环流反应器的一维两流体模型为基础,推导出了反应器的能量方程。分析了反应中的功耗分配规律,并以此对反应器中的流动规律作了较合理的解释。本文还从理论和实验上较全面地讨论了反应器操作参数和结构参数对气含率和循环液速等的影响。 An internal circulation gas lift reactor with a diameter of 0.186m and a height of 3m was established. The gas holdup and velocity in the reactor were measured electrochemically. Based on the one-dimensional two-fluid model of the gas-lift loop reactor obtained in (1), the energy equation of the reactor is deduced. The distribution law of power consumption in the reaction was analyzed, and the law of flow in the reactor was explained reasonably. In this paper, the effects of reactor operating parameters and structural parameters on gas holdup and circulating liquid velocity are also discussed theoretically and experimentally.
