工业冷却水中氯离子的含量一直为人们所关注,认为高氯离子水会引起设备的腐蚀。在一些大型工程的建设中,为了取得氯离子含量较低的水有时要开挖长距离引水工程。如石化总厂的黄浦江一期引水工程、宝山钢铁总厂原计划的淀山湖引水工程、嘉定宝山内河调蓄方案等。但是,冷却水中氯离子对腐蚀到底有什么影响,氯离子含量允许多少,高氯离子水能否作为石油化工、冶金及其它工业的冷却用水,用高氯离子水来冷却工艺过程如何采取措施来避免或缓和腐蚀,长期以来人们对这些问题的认识模糊,以致在一些大型工程决策方案时,缺乏充分的科学依据,可能会造成巨大的浪费。因此弄清这些问题有重大的经济意义。我厂从1979年开车以来长期使用高氯离子的水作为冷却水,现将我厂高氯离子水的 Chloride content in industrial cooling water has always been of concern, that high chloride ion water can cause corrosion of equipment. In the construction of some large projects, in order to obtain low-chloride water, sometimes digging long-distance water diversion project. Such as the petrochemical plant Huangpu River a water diversion project, Baoshan Iron and Steel Plant planned Dianshan Lake diversion project, Jiading Baoshan inland river regulation program. However, the impact of chloride ion in cooling water on corrosion in the end, the amount of chloride ions allowed, high chloride ion water can be used as petrochemical, metallurgical and other industrial cooling water, high chloride water to cool the process how to take measures to Avoiding or alleviating corrosion has long been a vague understanding of these issues. As a result, the lack of adequate scientific evidence in some large-scale engineering decision-making programs can cause enormous waste. Therefore, it is of great economic significance to clarify these issues. I plant from 1979 car long-term use of high-chloride water as cooling water, now I plant high chloride water
