摘要
在循环水冷却系统中,由于冷却塔的蒸发会使系统中各种盐份的含量逐渐升高,循环水中的碳酸根碱度和硬度值达到一定程度,就会导致凝汽器铜管的结垢。通常,由小型试验所确得的循环水的最高允许浓缩倍率是控制循环水排污的依据。而循环水的浓缩倍率与缓蚀阻垢剂的性能有重要关系,在使用过程中要必须对缓蚀阻垢剂的性能进行评定。
循环水在浓缩蒸发过程中,各种离子的浓度随浓缩倍率的增大而增大,当浓缩倍率达到一定数值时,二氧化碳溢出,产生碳酸盐沉淀,此时水中的碳酸盐碱度就是极限碳酸盐碱度。据此可以计算出极限浓缩倍率。加入阻垢剂的目的,就在于提高其极限碳酸盐碱度,其极限值越高,其阻垢效能也越好。
本文介绍了用动态极限碳酸盐法,在小型模拟试验的环境下,按照一定的试验条件和试验方法,对永昌发电公司缓蚀阻垢剂阻垢性能和缓蚀性能进行评定。对缓蚀阻垢剂的阻垢和缓蚀机理进行了分析,针对永昌发电公司循环水水质、运行状况,按照国家和行业标准,确定缓蚀阻垢剂的投加量,分析了在缓蚀阻垢剂的使用过程中应遵循安全技术措施。

ABSTRACT
In the circulation water cooling system, because of evaporate of cooling tower will make the various salt in the system of content gradual go up, circulation aquatic carbonic acid root alkalinity and degree of hardness value attain certain degree, will cause the Ning vapor machine copper tube of knot , from small scaled experiment indeed get of circulation water of tallest allow inspissation magnification is control circulation water row dirty circulation water of concentrated magnification and the function of water steady have importance relation and want to have to carry on assess to the function of water steady in the usage the process.
Circulation water is in the inspissation the evaporation the process, the density of various ion with concentrated magnification of enlarge but enlarge, be inspissation magnification to attain certain number, carbon dioxide overflow, creation the carbonate precipitate, the aquatic carbonate alkalinity is an extreme limit carbonate at this time to time can calculation extreme limit concentrated Zu dirt the purpose of, lie in the carbonate alkalinity of the exaltation its extreme limit, its extreme limit value more Gao, the its Zu dirt effect be also more good.
