Abstract

Abstract:

There is exchanging of CO₂ between circulating cooling water and the atmosphere. Since the circulating cooling water system runs continuously, the CO₂equilibrium can be produced between them. Then the pH can be calculated exactly with the formula. The control range of pH is closely relative to the concentration multiplying power，and also has important effect on water saving and corrosion.

Key words: alkalinity, pH, aeration, carbonate equilibrium

摘要：

循环冷却水中和空气中的CO₂之间存在交换,由于循环冷却水系统的连续运行,冷却水中和空气中的CO₂达到平衡,此时的pH可由公式准确计算。pH的控制范围同循环水的浓缩倍率有密切关系,并对节水和腐蚀有重要影响。
