摘要
本文针对循环水冷器的泄漏现象,从腐蚀机理、腐蚀类型以及腐蚀因素等方面进行了详细分析,以及对其他炼油厂的水冷器腐蚀失效的了解,我们认为循环冷却水水质、温度、流速以及微生物粘泥、悬浮杂质的沉积、水侧管壁结垢等是造成水冷器腐蚀泄漏的主要原因,并就此提出了相应的对策。
This paper analyzes the leakage phenomenon of circulating water cooler from corrosion mechanism, corrosion types and corrosion factors and so on.We think that the water quality, temperature, flow rate of circulating cooling water, microbial slime, suspended impurities deposition, water side pipe wall and scaling is the main cause of corrosion and leakage of water coolers, at this point,we have put forward corresponding countermeasures.
