设计了一种Taylor vortex光催化反应器，通过将流体从本体再循环到包覆TiO2的内筒壁上，在两个共轴筒之间产生非定常Taylor- couette流。系统地研究了三种不同有机化合物的流动发展和光催化降解。比较了不同雷诺数和催化剂负载对光催化降解的影响。实验结果表明，即使催化剂是固定的，Taylor vortex光催化反应器也很有希望用于水净化，因为浆体和固定体系的总体降解率没有显著差异。(C) 2004 Elsevier Ltd.版权所有。
A Taylor vortex photocatalytic reactor was developed that creates unsteady Taylor-Couette flow in between the two co-axial cylinders by re-circulating fluids form bulk to the inner cylinder wall, which was coated with TiO2. Systematic investigation for flow development as well as photocatalytic degradation of three different organic compounds was carried out. The effect of Reynolds number and catalyst loading on photocatalytic degradation were compared for both slurry and fixed catalyst system. The experimental results demonstrate that Taylor vortex photocatalytic reactor is promising for water purification even when catalyst is fixed, as there is no significant difference in overall degradation rate between slurry and immobilized systems.
