用鼓风爐炼铜的冶炼过程中,烧結机担負有烧結与焙烧的双重任务;将选矿所得的极細粒精矿烧結成块与焙烧掉一部份硫,因此烧結机除去产出滿足生产的多孔状烷结块外,还产出大量含有SO_2的烟气。这种烟气若不加以处理以去掉SO_2,而排入烟囱送入空中散布于附近大气中,这样就产生两个問題: 1.大量有毒的SO_2长时間弥漫于空气中,使冶炼厂附近周围数十里内地表植物以及江河中的魚类动物都遭受严重的恶劣影响; 2.使大量对工业及农业发展有重要意义的硫磺未回收利用,造成不可弥补的損失。由于此种烟气中所含SO_2很低,平均为2～3
Smelting furnace with blast furnace smelting process, sinter sintering and roasting assume the dual task; the beneficiation of the ultrafine particles concentrate sintered and roasted off a part of the sulfur, so the sintering machine removed Output to meet the production of porous alkane cakes, but also produce a lot of smoke containing SO2. This flue gas, if left untreated to remove SO2 and discharged into the chimney into the air and scattered in the nearby atmosphere, poses two problems: 1. A large amount of toxic SO2 diffuses into the air for a long time, causing the vicinity of the smelter Surface plants on the surface of dozens of miles and fish species in rivers and rivers have suffered serious adverse effects; 2. Unreasonable losses have been caused by a large amount of sulfur that is of great significance to industrial and agricultural development and has not been recycled. Due to the low SO 2 content in this flue gas, the average is 2 ~ 3
