气提式环流反应器的应用日趋广泛,但对其中固相悬浮的机理仍不够清楚,反应器传统的锥底是否适合固树悬浮仍有待理论和实验的验证.本文在小型环流反应器中试验了平底瓦两种深浅不同的截头雄底对悬浮离子交换树脂的影响.实验结果表明,对上流式(指中心管内流向)操作,平底优于推底;对下流式操作,深浅适中的雄底效果最好.因此,三相环流反应器的优化还需在理论的指导下继续深入.
However, the mechanism of solid phase suspension is still not clear enough. Whether the traditional conical bottom of the reactor is suitable for solid-tree suspension remains to be verified theoretically and experimentally. In this paper, the effect of two different truncated masters of flat-bottom tile on suspended ion exchange resin was tested in a small loop reactor. The experimental results show that for the upflow type (referring to the central tube flow) operation, the flat bottom is better than the push bottom; for the downflow operation, the midsole with the moderate depth is the best. Therefore, the optimization of the three-phase loop reactor needs to be continued under the guidance of the theory.
