Application Research On Baggy Excision Lampblack Skill In Flast Furnace Gas

Iron and steel industry consumes much energy source and water. Today, energy crisis, water crisis and environmental protection's pressure forces iron and steel industry have to develop toward conserve energy, water and environmental protection. One of iron-smelting production-blast furnace gas,there are much hot-energy, chemistry-energy, pressure-energy and powder dust in it. If it is dealed with excision lampblack, it is used steel works, iron works, rolling mill etc, and realizing hot-electricity union production. Enterpriz's cost of production and energsoure consumption is marked drop, and economic results is marked risen. Traditional watery mathod excision lampblack can fairly remove gas's dust, but through excision lampblack a lot hot is lost, and pressure is drop. There is a lot mechanical water in gas, Gas' hot-energy, pressure-energy, chemistry-energy is warked decreased. If gas' disposition is used baggy, the energy of gas is fairly reserved. There isn't mechanical water in gas. And excision lampblack's effect is good. environmental results and economic results are remarkable.Baggy excision lampblack's skill is better perfect in internal small flast furnace. And it have to be completed in internal large or middle flast furnace. The article associates with engineering actuality of chongqing iron and steel corporation's 750m3 flast furnace, and analyses gas prodution, rationale of baggy excision lampblacke, influence factor on using baggy device to process gas of furnace. It probes reasonable technology of baggy excision lampblack system, design of gas' pipeline system, enter gas pattern of filter, filtration's fashion, filter fiber's characteristic and selection, rational filtration load, cleaning dust mathod of filter, the way of unloading and convey, system safe operation's measure. It also is directed against the problem in system operation, looks into the cause, studies improving's measure, and overall analysis practical result. It advances system have to perfect and enhance's technology. It produces reference for system's optimization. It appraises the project form encomy results and environment results.
