Background
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 coal dust, heavy oil, natural gas and the like) at high temperature is combusted with oxygen blown into air to generate carbon monoxide and hydrogen, and oxygen in iron ore is removed in the ascending process in the furnaces, so that iron is obtained by reduction. Blast furnace gas is a byproduct combustible gas in the blast furnace ironmaking production process. Its composition is mainly formed from 6-12% of carbon dioxide, 28-33% of carbon monoxide, 1-4% of hydrogen, 55-60% of nitrogen gas, 0.2-0.5% of hydrocarbon and small quantity of sulfur dioxide. Its dust concentration is 10-50 g/cubic meter (standard condition), and its dust-producing quantity is averagely 50kg/t (pig iron) -75kg/t (pig iron). The dust has particle size below 500 μm, and mainly comprises iron, ferrous oxide, aluminum oxide, silicon oxide, magnesium oxide and coke powder.
This application improves to prior art, and the inside air current of clean gas case among the prior art distributes unevenly, easily leads to the import to rock the collision to the offside sack and appear the damage, and the part still occupies the inside space of box, reduces the quantity of sack.
