Description

A kind of water washing and dust removal device for steelmaking

technical field

The utility model relates to the technical field of smoke and dust removal, in particular to a steelmaking water washing smoke and dust removal device.

Background technique

The pig iron used for steelmaking is put into the steelmaking furnace and smelted according to a certain process to obtain steel. Steel products include steel ingots, continuous casting slabs and direct casting into various steel castings. Generally speaking, steel generally refers to steel rolled into various steel products. Steel belongs to ferrous metal but steel is not exactly equal to ferrous metal. Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio of elements to obtain the best performance.

In the steelmaking process, one of the important processes is to put the raw materials into the steelmaking furnace for smelting. In this process, a large amount of rust, moisture and other impurities may be mixed in the steelmaking raw material pig iron, which makes the smelting in the steelmaking furnace A large amount of smoke and dust will be generated during the process, and if these smoke and dust are directly discharged into the air, it will cause great harm to the air and directly affect the living environment of nearby residents.
