摘要

采用在线监测和手工分析相结合的方法，突出研究了天然循环冷却水（松花江水）中铁离子、细菌总数、pH值、溶解氧、浊度、电导率等水质参数与板式换热器内冷却水污垢热阻的关系。结果表明：板式换热器冷却水污垢热阻值比TEMA标准值小，且不存在诱导期；pH值和溶解氧影响铁腐蚀速率和细菌总数的变化，而浊度和电导率的变化又受细菌总数的影响；它们在运行初始阶段对结垢特性影响较大，而后进入平缓期。混合污垢间存在协同效应，减小溶解氧和细菌总数的含量可以起到抑制结垢的目的。

Abstract

The relationship between fouling thermal resistance in a plate heat exchanger and water quality parameters such as iron

total bacteria

dissolved oxygen

turbidity and conductivity in the Songhua River water was investigated.Results show that the value of the fouling thermal resistance in the plate heat exchanger is lower than that of Tubular Exchanger Manufacturers Association (TEMA)

and the natural cooling water has no induction period.pH and dissolved oxygen influence the iron corrosion rate and total bacteria

which affects the turbidity and conductivity.All these parameters have considerable effects on the heat transfer performance in the initial period

and then the effects are less.There exists synergetic effects from different fouling causes

and the fouling can be inhibited by reducing the amount of dissolved oxygen and total bacteria.
