| 中文摘要: |
| 以A、B、C三种有机酸清洗剂为研究对象，筛选出性能较好的清洗剂并优化其清洗工艺参数，结果表明，清洗剂C与水的体积比为1∶20、清洗温度为20~40℃、清洗时间为1 h时，除垢率达97%，且对碳钢和不锈钢的腐蚀率为三种清洗剂中最低，满足化学清洗对腐蚀率的要求.在此基础上，建立动态除垢实验装置考察实际清洗效果，结果表明，清洗剂C实际清洗效果较好，除垢后清洗试件在管程流速分别为0.5、0.7、0.9、1.1 m·s-1时，传热系数分别提高6.01%、6.98%、6.93%、9.04%. |

| Three organic acid cleaning agents A,B and C were used for the best cleaning agent selection and the cleaning process optimization.The results showed the highest cleaning rate of 97% was achieved with the volume ratio of cleaning agent C and water of 1:20,the temperature range of 20~40℃ and cleaning time of 1 h.The lowest corrosion rate of carbon steel and stainless steel was achieved,which could meet the requirements of chemical cleaning.The dynamic cleaning experiments were conducted to verify its cleaning effect.The results showed that the heat transfer coefficients increased by 6.01%,6.98%,6.93% and 9.04% after cleaning when the flow rate of the inner tube was 0.5,0.7,0.9 and 1.1 m·s-1,respectively. |
