Description

Technical Field

[0002] During the distillation process, the steam temperature in the distillation tower is very high. The condenser cools the high-temperature and high-pressure steam into liquid by using cooling water or other cooling media. This step is the key to reducing the changes in pressure and temperature and ensuring the stability in the distillation tower. After passing through the distillation tower, the liquid substances are collected by the condenser. These condensed liquids can be returned to the tower body and continue to cycle through repeated evaporation and condensation processes to achieve the purpose of separating and purifying liquid substances. The recovery efficiency of the condenser directly affects the separation effect.
