摘要
研究采用空气-蒽醌工作液体系模拟过氧化氢生产中蒽醌氢化用三相反应器内流体的流动情况。首先建立了实验测定部分发泡固定床内泡沫流持液量的方法。然后应用建立的方法测定了不同气液表观流速下动态持液量,并考察了气液表观流速对动态和总持液量的影响。最后,比较了10种用于估算发泡体系泡沫流区持液量经验式的计算精度。结果表明,分别采用Specchia和Larachi经验式估算动态和总持液量的计算误差均在5%以内。
In order to obtain the accurate relationship for the total and dynamic liquid holdup of foaming flow in the three-phase packed-bed used for hydrogen peroxide production by anthraquinone process. Air and anthraquinone working solution system was selected to simulate the fluid flow in the real reactor. At first, a method to measure liquid holdup for the foaming flow was initially established, and then the effect of gas and liquid superficial mass rate on the dynamic and total liquid holdup were discussed in detail. Finally, by comparison of 10 empirical relations for liquid holdup, it's indicated that Specchia and Larachi's correlations can be used to predict the dynamic and total liquid holdup of the foaming flow in the Three-phase packed-bed for hydrogenation of anthraquinone with an accuracy of 5%, respectively.
