摘要
主要进行了供热系统在不同温度时的清水、添入十六烷基三甲基氯化铵(CTAC)和聚丙烯酰胺(PAM)时减阻特性的比较研究,通过实验数据可以得出,30℃时在供热管网系统中添入聚丙烯酰胺减阻效果最佳,随着温度升高减租剂减阻性能逐渐降低,聚丙烯酰胺到60℃时丧失减阻性能并使热网压损增大。CTAC最大减阻效果达到25.7%,聚丙烯酰胺最高达到40.68%。
This paper mainly studies the drag reduction characteristics of the heating system at various temperatures,and compares the characteristics of water with additives cetyltrimethyl ammonium chloride(CTAC) and polyacrylamide(PAM).Ac-cording to experimental data,we can see that in 30 ℃ heating network system,the effect of adding polyacrylamide is the best.The drag reduction of additive is gradually reduced with the increasing of temprature.In 60 ℃,the polyacrylamide loses the drag reduction,and pressure loss of heating network system increased.The highest friction reduction efficiency with 20ppmCTAC can reach 25.7%,and the highest friction reduction efficiency with polyacrylamide could reach 40.68%.
