[0002] Hot dip galvanizing is a common anti-corrosion treatment method, but a large amount of waste heat is generated during this process. Effectively recovering these waste heat resources is crucial for environmental protection and energy utilization.

[0003] In traditional hot dip galvanizing processes, a large amount of thermal energy is discharged into the atmosphere in the form of waste gas, which not only causes energy waste but also has a certain impact on the environment. To solve this problem, some waste heat recovery technologies have been developed, but these technologies often have problems such as low recovery efficiency, complex equipment, and high costs.
