我厂5L-40/8和4L-40/8往复式空压机的冷却系统用水是利用全厂主机循环水。夏季水温高,水质未进行过滤和软化处理,杂质较多,致使空压机缸体水套、中间冷却器、循环水管等处结垢严重,且无法清洗,造成冷却效果不良,出口温度高达170℃。自1981年投产至今,空压机缸体水套未清洗过,结垢厚度平均为3.5mm,中间冷却器φ12紫铜管内壁有1/3结垢。冷却水阀门全部打开,水量也不足。对空压机的正常运行及安全生产造成很大威胁。为此,我们采用了化工部机械研究院化学清洗总公司研制的“兰
I plant 5L-40/8 and 4L-40/8 reciprocating air compressor cooling system water is the use of the host plant circulating water. Summer water temperature is high, the water quality is not filtered and softened, more impurities, resulting in air compressor cylinder jacket, intercooler, circulating water pipe scaling serious, and can not be cleaned, resulting in poor cooling effect, the outlet temperature up to 170 ℃. Since 1981 put into operation so far, the air compressor cylinder water jacket is not cleaned, the average fouling thickness of 3.5mm, intermediate cooler φ12 purple tube wall has 1/3 fouling. Cooling water valves are all open, the water is not enough. Air compressor on the normal operation and safety pose a great threat. To this end, we have adopted the Ministry of Chemical Industry Institute of Chemical Chemical cleaning company developed "blue
