The Influence of the Inclined Angle and Circulating Flow Rate on the Performance of Flat-plate Type Photocatalytic Reactor
倾角和循环流量对平板型光催化反应器性能的影响

This paper investigated the influences of inclined angle and circulating flow rate on the flow characteristics and performance of the flat plate reactor,the optimum inclined angle for the flat plate reactor under radiation of solar light was also discussed.The results showed that the water volume(V) and film thickness(b) on the flat plate were separately correlated with the inclined angle and the circulating flow rate.Under the condition of same radiation on the flat plate,the reactor performance increased with decrease of the inclined angle and increase of the circulating flow rate in the suspended catalyst system,while in the immobilized catalyst film system,the reactor with the flat plate of 1m×0.48m had the highest performance as the circulating flow rate was 500L/h and the inclined angle was 10°,the corresponding Renold number was 286.Also under the condition of the same radiation,whether in the suspended catalyst system or in the immobilized catalyst film system,periodic radiation would increase the reaction rate.
