板式换热器内漏故障分析与处理

Analysis and Treatment of Internal Leakage in Plate-Fin Heat Exchanger

板式换热器流程制氧机在日常生产过程中发生氮气产品纯度超标现象。经过分析和推断,确定了导致该现象发生的根本原因是板式换热器内部泄漏。根据生产和设备实际情况,制定并实施了切实可行的板式换热器处理修复方案,最终取得了较好的运行效果。

Nitrogen purity exceeds the standard during everyday production of oxygen generator using plate-fin heat exchanger process. Through analyzing and concluding, the basic cause of the problem was found to be an internal leakage in the plate-fin heat exchanger. Based on the actual condition of production and equipment, some practical restoration plan for the exchanger was drawn up and carried out, which has achieved good operation effect.
