摘要
莱钢265m2烧结机通过采用沉降式微负压抽风除尘技术和水幕墙除尘技术,优化混合机加水方式,密封处理混合机进料端等措施,彻底解决了区域扬尘问题,有效抑制二次扬现象,提高了二混造球质量,降低了固体燃耗,1#265m2烧结机粉尘浓度由治理前的185.4mg/m3降为治理后的7.9mg/m3,实现了达标排放。
Through using dedusting technology by drawing wind with micro-negative pressure and dedusting technology with water wall, optimizing adding water type of mixing machine, closed feeding end of mixing machine and so on, the problem of flying dust was solved in field, the problem of second flying dust was restricted, the pelletizing quality of second mixing was risen and solid fuel consumption was decreased in Laiwu Steel＇ s 265 m^2 sintering machine. The dust thickness of No.1 265 m2 sintering machine was decreased from 185.4 mg/m3 （before government） to 7.9 mg/m3 （after government） and the emission of reach the standard was achieved.
