针对船舶压载水排放要求,结合当前船舶压载水处理技术,采用紫外技术设计处理量为200 m3/h的压载水装置。基于紫外线的工作原理,设计了新型UV压载水处理装置,其中包括灯管的选择、腔体结构的设计和紫外线辐照强度、剂量的计算等。采用Fluent软件分别对新型与原型UV装置内的流场分布、流体过流时间进行数值模拟;分别采用Fluent和Mat-lab软件对装置内的紫外辐照强度和辐照剂量进行仿真模拟,并将模拟结果进行对比分析。模拟结果显示,新型UV装置内的流体过流时间与辐射剂量较原型装置均有所增加;与Fluent软件相比较,Matlab软件能够精确计算装置内各点的UV强度与剂量,且模拟过程更加简便,对UV装置展开深入的研究提供了一种定量分析的新方法。

In view of the requirements for ship's ballast water discharging,combining with current technologies, ultraviolet technology is used in the design of ship's ballast water treatment devices. Based on the working princi-ple of the ultraviolet ray,a new UV ballast water treatment device is designed. The design includes selection of tubes,the calculation of ultraviolet doses and the design of cylinder bodies,etc. The flow field and residence time of the UV device are simulated by the Fluent software,and the UV intensity and dose are calculated by both Fluent and Matlab. The results show that compared with the prototype UV device,both the residence time and UV dose of the new UV device increase;compared with the Fluent software,UV intensity and dose of each point in the UV device can be calculated by Matlab accurately and it's process of simulation is easier,and it provides a new method for quantitative analysis of the further study of intensive UV device.
