Description

Technical Field

[0001] The utility model relates to the field of dust removal of iron-making blast furnaces, in particular to a dust removal device for blast furnaces. Background Art

[0002] Rebar is the common name for hot-rolled ribbed steel bars. Rebar is widely used in the construction of civil engineering projects such as houses, bridges, and roads. From large public facilities such as highways, railways, culverts, tunnels, flood control, dams, to small foundations, beams, columns, walls, and slabs of house buildings, rebar is an indispensable structural material.

[0003] The production of rebar requires the use of blast furnace ironmaking equipment. Blast furnace ironmaking is one of the important steps in producing steel. Modern blast furnace ironmaking is transformed and developed from the ancient vertical furnace ironmaking method. Although many ironmaking methods have been researched and developed in various countries around the world, blast furnace ironmaking is still the main method of modern ironmaking because of its relatively simple process, large output, high labor productivity and low energy consumption. During blast furnace ironmaking, a large amount of flue gas containing heavy metals will be generated, and the flue gas contains a large amount of dust. Most of the current dust removal devices for blast furnaces simply filter the flue gas, with poor dust removal effect, and it is inconvenient to replace the filter plate, which reduces the dust removal effect of blast furnace flue gas. For this reason, we propose a dust removal device for blast furnaces to solve the above problems. Utility Model Content
