【摘要】 针对河南某氮肥厂循环冷却水系统的腐蚀结垢特点,结合冷却水系统的垢质分析,通过溶垢、腐蚀挂片试验等,研究确定了中性清洗剂不停车清洗方法,并对不停车化学清洗方案进行了研究。根据现场检测,清洗效果良好。更多还原

【Abstract】 According to the corrosion and scaling features of the circulating cooling water system in a nitrogenous fertilizer plant in Henan,an analysis was made of the scale mass of the cooling water system and,through dissolution and corrosion coupons and tests,the on-line cleaning approach was used with neutral cleaning agents,on basis of which the on-line chemical cleaning solution was studied.Field detection shows that the cleaning is good.更多还原
