| 摘 要： | 顺流式紫外消毒器中灯管布置方式对消毒效果有很大影响,采用数值模拟的方法对紫外消毒器中灯管不同布置方式下的运行效果进行模拟比较。结果表明:通过改变消毒器中灯管的布置方式,可以有效改变消毒器内的辐射场和粒子受到的辐射剂量。在所研究的3种布置形式中,五边形均布形式的消毒器中辐射光强和辐射剂量分布更加均匀,而且粒子所受辐射剂量明显提高,可以产生更好的消毒效果。

| Abstract: | T he tube arrangement has great impact on the performance of dow nstream type ultraviolet disinfection reactor . The operating results of ultraviolet disinfection reactors with three different types of tube arrangement are simulated by using FLUENT .The results show that the fluid field and the radiation dose can be enhanced w hen the tube arrangements are changed .The fluid velocity , radiation area , and radiation of UV disinfection reactors with pentagonal distributed tubes are more uniform ,so that it has better disinfection results . |
