Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing processing, in particular to an acid mist absorption and treatment device for hot-dip galvanizing processing. Background Art

[0002] Hot-dip galvanizing is a common surface treatment method used to protect metal parts (usually steel) from damage due to corrosion. During the hot-dip galvanizing process, the metal parts are first pickled and degreased, and then immersed in molten zinc for galvanizing. At high temperatures, the zinc reacts with the metal surface to form a zinc coating, which can provide effective corrosion protection. The advantages of hot-dip galvanizing include higher corrosion resistance, long-term protection and beautiful appearance. However, hot-dip galvanizing will produce waste gases such as acid mist and carry environmental pollution and health risks, so appropriate measures need to be taken to deal with and reduce the impact of these emissions.

[0003] At present, a simple acid mist purification tower is usually used in the existing hot-dip galvanizing process to absorb and purify the acid mist. However, in this way, the acid mist stays in the acid mist purification tower for too short a time, and the purification effect of the acid mist is not sufficient. Continuous emission will cause certain harm to the environment and workers. Therefore, we propose an acid mist absorption and treatment device for hot-dip galvanizing processing.
