   The iron and steel industry is the first big users of air filter, air filter cotton in the proportion of iron and steel industry has accounted for 95%.Including raw materials, carbonization, lime, blast furnace tank on tank under, out of the field of iron and iron pretreatment, the cast iron machine, secondary dedusting of converter, steelmaking eaf dust source point dust removal, steel rolling process.Bag dust removal technology mature, reliable, stable, in addition to efficient dust removal, can also recycle much of your precious resources.

 

    Air filter dust removal iron and steel industry technology progress and application of the most significant performance in blast furnace gas purification. We use wet flue gas purification of the traditional process, high energy consumption, water consumption is big, strong corrosion, water treatment of the high cost of investment,So change the wet to dry is basically universal energy conservation to reduce blast furnace gas bag dust removal technology.At present, the large blast furnace gas showed a strong momentum of bag-type dust collector, 2007 air blast furnace gas purification filter cotton has been successful. Dry cleaning blast furnace gas using bag dust removal technology replaced the traditional two-stage venturi wet dust removal technology.Its outstanding advantage is that the total investment to save 3016, covers an area of 50, 96, the production of iron per ton water saving 200 kg, saving electricity was above 7094, and recycling of coal gas water content increased significantly. Application of the technology can reduce the management at the same time, greatly reduce soot emissions and waste emissions.

 

    Sinter machine the nose and the tail dust removal of iron and steel industry are mostly by electric dust collector.The soot emission standard up to 50 mg/m3, some cities and enterprises discharge standard limit up to 20-30 mg/m3.For fine particulate matter less than 10 microns, using conventional electricity, dust collector efficiency capture difficult, such as increasing electric field or electric field expanding, its investment, energy consumption and operation cost will be increased significantly, is still difficult to satisfy.In recent years, many companies began to change used bag bag. Desulfurization of sintering machine head is the main task of the flue gas purification, air filtration in half dry process desulphurization cotton can be widely used.Carbon concentration can be greatly reduced to 20 a 30 mg/m3, stable running, not being affected by the fluctuation of the working condition of sintering machine, greatly improve the factory and the surrounding environment.

 

    Adopt the ferroalloy electric furnace flue gas is the air filter cotton, and the use of high temperature filter material. According to the national industrial policy, small ferroalloy furnace to be being washed out gradually, thus large air filter cotton broad prospects in ferroalloy electric furnace flue gas purification.Nonferrous metallurgy copper, lead and zinc smelting furnaces white flue gas purification should use air filter cotton, overall non-ferrous metallurgical industry of environmental protection is relatively backward, reconstruction work is false, the demand for air filter cotton is bigger.

 

    Air filter cotton equipment becoming larger work. Cement line jealous raw meal grinding, cement mill, kiln head, preheater with air filter cotton dust catcher of processing the air volume is more and more big, the cement industry air filter cotton bag dusting of industry a bright spot in 2009.
