Description

Technical Field

[0001] This utility model relates to the field of zinc fume dust removal technology, and in particular to a zinc fume dust removal device for hot-dip galvanizing of metal products. Background Technology

[0002] In the hot-dip galvanizing process, dust removal devices are widely used to remove zinc fumes. Metals generally refer to a class of substances that have a unique luster but are opaque, ductile, and have thermal and electrical conductivity. In a narrow sense, metals are simple substances composed of metallic elements, most of which are excellent conductors of electricity and heat. Dust removal devices are also used in the hot-dip galvanizing process.

[0003] In the existing hot-dip galvanizing process, rust-removed steel parts are immersed in molten zinc to coat the surface of the steel parts with a zinc layer, thereby achieving the purpose of corrosion prevention. Since zinc is a flammable metal, zinc gas will directly disperse around the zinc pot during the hot-dip galvanizing production process.

[0004] However, existing dust removal devices cause zinc fumes to permeate the entire galvanizing workshop during use, making it impossible to remove zinc from the fumes. Zinc particles also pollute the surrounding environment, resulting in poor performance. To address these issues, a zinc fume dust removal device for hot-dip galvanizing of metal products is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a zinc fume dust removal device for hot-dip galvanizing of metal products, which solves the problems in the background technology where zinc fumes permeate the entire galvanizing workshop, making it impossible to remove zinc from the zinc fumes, and zinc particles will pollute the surrounding environment, resulting in poor performance.
