针对供热系统中的板式换热器屡遭腐蚀穿孔的现象,经深入分析发现其根本原因是酸性腐蚀。试验了腐蚀治理的几种措施,包括将锅炉排污水加入换热站补水箱、系统加碱法以及改造离子交换系统。根据试验结果,最终确定将钠离子交换系统更换为H-Na离子交换系统,详细介绍了改造方案。
For the plate heat exchanger in the heating system repeatedly corroded perforation phenomenon, after in-depth analysis found that the root cause of acid corrosion. Several measures of corrosion control were tested, including adding waste water from the boiler into the reboiler tank, adding alkali to the system, and reforming the ion exchange system. According to the test results, it is finally determined that the sodium ion exchange system will be replaced by the H-Na ion exchange system, and the modification scheme will be introduced in detail.
