New ideas for energy savings – Creative approaches to evaporative vapor recovery in circulating water cooling towers
Thread Content
At present, domestic chemical enterprises use cooling towers to cool their circulating water; this method relies on the evaporation of water to remove heat and thereby lower the temperature of the circulating water. A large amount of pure water evaporates into the atmosphere, resulting in a loss of local water resources. Researching current water recycling systems, particularly those that recover water lost through evaporation in cooling towers, could involve the use of large-scale canopy-type recovery devices. These systems involve processes such as collection, air induction, condensation, and recycling; further research is needed to address these details in order to reduce waste of industrial water resources and alleviate the severe situation regarding global water supplies.
It might be feasible to build a new one, but the question is how the foundation of the old tower can support it
Replacing open cooling towers with closed-loop cooling towers utilizes mature technology available in China, which can save 5% in water usage. Both the Zhongtian Hechuang project and the Datong 600,000-ton methanol project have industrial applications.
