Description

Technical Field

[0001] The utility model relates to the technical field of steel slag treatment, in particular to a steel slag treatment and dust removal device. Background Art

[0002] Steel slag is a byproduct of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts formed by the reaction of these oxides with solvents. Steel slag contains a variety of useful ingredients: 2% to 8% metallic iron, 40% to 60% calcium oxide, 3% to 10% magnesium oxide, and 1% to 8% manganese oxide, so it can be used as a raw material for steel metallurgy.

[0003] There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle it in the factory as a smelting solvent, which can not only replace limestone but also recover a large amount of metallic iron and other useful elements from it. The other is to use it as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers.

[0004] The slag dust removal device is an auxiliary device for timely absorbing the smoke and steam generated during the slag recovery process. The existing technology uses water mist to treat the smoke, which wastes a lot of water resources and has poor treatment effect. The treated water mist also needs to be filtered before it can be discharged, and the procedure is complicated. Utility Model Content
