Description

Dust removal device for blast furnace iron-making batching station

Technical Field

The utility model relates to a dust removal technical field specifically is a blast furnace ironmaking batching station dust collector.

Background

Blast furnace ironmaking is an important link in steel production. Blast furnace ironmaking is developed and improved by ancient shaft furnace ironmaking. Although many new iron-making methods are researched and developed in various countries in the world, because the blast furnace iron-making technology has good economic indexes, simple process, large production capacity, high labor productivity and low energy consumption, the iron produced by the method still accounts for more than 95 percent of the total iron production in the world. In the production of a blast furnace, iron ore, coke, and a flux (limestone) for slag formation are charged from the top of the furnace, and preheated air is blown through tuyeres located along the periphery of the furnace at the lower part of the furnace. Carbon in coke (some blast furnaces also blow auxiliary fuel such as pulverized coal, heavy oil, natural gas, etc.) and carbon monoxide generated by combustion of oxygen blown into the air are reduced to obtain iron by removing oxygen in iron ore during the rise in the furnace. The smelted molten iron is discharged from the iron notch. The unreduced impurities in the iron ore are combined with fluxes such as limestone to generate slag, and the slag is discharged from a slag hole. The generated gas is led out from the top of the furnace, and is used as fuel of hot blast stoves, heating furnaces, coke ovens, boilers and the like after dust removal.
