摘要

为探讨铁细菌在板式换热器里的污垢规律，对不同流速、温度及浓度下铁细菌在板式换热器内的污垢特性进行了实验研究。结果表明：随着流速的增加，铁细菌的污垢热阻渐近值逐渐减小；随着温度的升高，铁细菌的结垢诱导期明显缩短，结垢速率加快，污垢热阻的渐近值呈减小的趋势；而随着浓度的增加，污垢热阻值呈现明显的增长。

Abstract

The bio-fouling characteristics of iron bacteria on plate heat exchanger was studied by several experiments to examine the impact of different flow velocity，temperature and concentration of iron bacteria. The results showed that the asymptotic value of heat transfer resistance of the plate heat exchanger

due to the bio-fouling

decreased gradually with increase of flow velocity. With increase of temperature，induction period of iron bacteria fouling cut down obviously，the rate of fouling accelerated，and the asymptotic value showed a reducing trend. With increasing concentration of iron bacteria

increase of the amplitude of heat transfer resistance of the plate heat exchanger was obvious because of the bio-fouling.
