水质参数与板式换热器结垢的关联
Relationship between water quality parameters and fouling in plate heat exchangers
摘要
Abstract
The relationship between fouling thermal resistance in a plate heat exchanger and water quality parameters such as iron, total bacteria, pH, 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.关键词
