净化系统设备管线故障判断与修理

Judgment and maintenance of purification system equipment and process pipeline faults

净化系统故障具体表现为设备故障及工艺管线故障等,本文结合变废锅系统给水预热器泄漏、脱碳系统低变煮沸器内漏及变换、脱碳、精致三工序间的工艺管线泄漏等故障实例,从故障原因分析入手,提出了解决故障的具体方案及预防措施,并总结了解决净化系统故障的基本原则,为维护平稳生产,确保高负荷运行提供保障。

Purification system fault includes equipment failure and process pipeline breakdown, etc. This pa- per starts from fault causes of some fault examples, which include leak of feed water preheater, inner leakage of low variable scalder in decarbonization system and process pipeline leakage among transformation, decarburization and delicacy systems. The specific solutions and preventive measures were put forward to these faults, furthermore, the basic principle of solving purification system failure was summarized to maintain stable production and ensure high load operation.
