De-dusting of Sintering Head and Tail Flue Gas
The sintering head and tail exhaust flue gas composition is complex, the sintering dust particles have many burrs on the surface and are hard, the appearance is rough, the grinding is very strong, and contains trace elements of sodium and potassium, it is easy to adhere to the inside of the equipment, and the dust contains 10-20% CaO, which is easy to scale in water. Due to the small amount of SO2 in the flue gas, the fumes are somewhat corrosive, especially when the flue gas temperature is lower than the dew point, severe acid corrosion will occur. The dust particles of the sintering head are fine, and the dust specific resistance is large. There are many dust collection points at the tail of the machine, and the dust concentration is large. Sintering head flue gas generally adopts electric dust removal, and tail gas generally adopts electric bag dust collector or bag type dust collector. At present, our company has made many achievements, including machine tail electric bag dust collector project of HBIS Group Xuansteel Company, HBIS Group Tangsteel Company and Shandong Xinhua Special Steel Group Co., Ltd. Machine head electric dust collector project of Shanxi Jianlong Industrial Co., Ltd and Jianlong Beiman Special Steel Co., Ltd , etc.
