The most likely leakage of switching heat exchanger is the welding line, especially the joint of the head and the pipeline. Most of the causes of leakage are the quality problems of manufacture and installation, which are also related to maintenance. The working condition of switching heat exchanger is poor. It is not only impacted by alternating airflow, but also changes greatly in airflow temperature. In long-term operation, the weak parts are easy to leak. Therefore, the welding quality should be strictly guaranteed during manufacture and installation. After installation, strict leak detection and pressure test must be carried out before driving, and problems should be dealt with timely to avoid passivity after driving. There are three methods to check whether the switching heat exchanger leaks in operation: 1) flow method. When a large amount of leakage occurs between the channel of product oxygen or product nitrogen and air channel, the output of oxygen or nitrogen increases ob...

Oxygen product: liquid oxygen is pumped out from the lower tower plate of the low pressure tower and sent to the storage tank, the inner compressed oxygen pump is placed next to the liquid oxygen storage tank, the liquid oxygen extracted from the storage tank is pressurized by the oxygen pump and sent out after gasification and reheating in the main heat exchanger to get the required oxygen product in liquid air separation plant. The nitrogen product is pumped from the top of the pressure tower...
