Description

Technical Field

[0001] The utility model relates to the technical field of zinc fume dust removal equipment, in particular to a zinc fume dust removal device for hot-dip galvanizing of metal products. Background Art

[0002] Hot-dip galvanizing is to first pickle the steel parts to remove the iron oxide on the surface of the steel parts. After pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip plating tank. During the hot-dip galvanizing process, a large amount of water vapor, chemical reaction smoke and splashing zinc will be generated during galvanizing. Hot-dip galvanizing dust is a white dust composed of ammonium chloride, zinc chloride and zinc oxide. It is highly acidic and has great harm to human health and the environment.

[0003] In order to deal with the smoke generated by hot-dip galvanizing, people usually use spray towers to carry out dust removal. At present, when the spray tower is performing dust removal, although the alkaline solution can effectively deal with the smoke, the particles in the smoke may adhere to the inner wall of the spray tower following the stirring of the stirring rod, which increases the subsequent cleaning workload and brings inconvenience to people's cleaning work.
