圆筒式紫外线消毒器灯管数和灭菌率的计算方法

Calculating Method for the Necessary Lampes and Sterile Ratein a TubeShaped Ultraviolet Air Washer

使用循环风的圆筒式紫外线消毒器比单纯紫外灯辐照灭菌有很大的优越性。国外已有矩形紫外线消毒器必要灯管数的计算公式，但有限定条件。本文进一步推导出圆筒形消毒器的必要灯管数和相应的灭菌率两个计算公式，两者可针对任何参数求出灭菌率，或按要求的灭菌率求出灯管数。计算结果得到实验结果和使用效果的很好印证。

t has much more advantage to use the cylindric ultraviolet air washer than to use the ordinary ultraviolet lamps. There was a calculation method for determining necessary lamps in a rectangled ultraviolet air washer, but it had a limiting condition. This paper developed two calculating methods for determining necessary lamps and its sterile rate in a tubeshaped ultraviolet air washer. The sterile rate can be extracted with any parameter. Necessary lamps can also be extracted with its sterile rate.
