After the condenser of the chlorination section was replaced, there was basically no leakage, bubbling, dripping or leaking on site, and there was never any chlorine leakage alarm of the condenser. The on-site environment was greatly improved, which greatly reduced the workload and maintenance costs of the mechanics. After the condenser was replaced for secondary crystallization, the water temperature of vacuum pool 3 was significantly lower than before, and the vacuum degree was basically stable at above -0.08Mpa. The dehydration time of each batch of materials was shortened by about 1 hour compared with before, saving steam consumption.
