化纤中水回用于循环冷却水系统的缓蚀阻垢研究

Corrosion and Scale Inhibition Performances of Reclaimed Water of Chemical Fiber Reused in Circulating Cooling Water System

根据对某化纤企业中水的水质监测,分析了化纤中水的水质特点和应用于循环冷却水所面临的问题,提出了系统水质稳定处理中的缓蚀阻垢要求,研制了针对化纤中水水质特点的高效缓蚀阻垢剂,测试了其在不同条件下的缓蚀阻垢性能,并在实际应用中取得良好的效果,解决了化纤中水回用于循环冷却水系统的腐蚀和结垢问题。

According to the monitoring and statistics on the reclaimed water quality of a chemical fiber enterprise, the characteristics of the reclaimed water quality and facing problems which the reclaimed water is reused in circulating cooling water system are analyzed. Therefore, it is presented that the corrosion and scale requirement in the process of the water quality stabilization system. On the basis of the characteristics of the reclaimed water, an efficient scale and corrosion inhibitor is developed. It is tested and researched that the corrosion and scale performance of the inhibitor under different conditions. （;ood results are achieved in practical applications. The corrosion and scale problems, which exist in the reclaimed water of chemical fiber reused in circulating cooling water system are solved.
