摘　　要：使用ICEM CFD软件建立光催化氧化设备工作腔体模型并划分网格,导入Ansys Fluent软件Do辐照模型,分析紫外光源(紫外灯管)对炼胶烟气处理效率的影响。结果表明:紫外灯管排列形式会影响工作腔体中辐照强度分布均匀性,从而对炼胶烟气处理效率产生影响;与紫外光源采用正方形排列时相比,紫外灯管采用菱形排列时工作腔体中辐照强度更大及其分布均匀性更好,对炼胶烟气的处理效率更高。该仿真结果可为橡胶厂炼胶烟气光催化氧化设备的设计提供参考。The working cavity model of photocatalytic oxidation equipment was established and meshed by using ICEM CFD software,and the Do irradiation model of Ansys Fluent software was introduced to analyze the influence of ultraviolet light source(UV lamps) on the treatment efficiency of rubber mixing fume. The results showed that the arrangement of UV lamps would affect the uniformity of the irradiation intensity distribution in the working cavity,which would affect the treatment efficiency of the rubber mixing fume. Compared with the square arrangement of the UV lamps,the diamond arrangement of the UV lamps had higher irradiation intensity and better irradiation distribution uniformity in the working cavity,and its treatment efficiency of rubber mixing fume was higher. The simulation results could provide a reference for the design of photocatalytic oxidation equipment for rubber mixing fume in rubber plants.
