摘要
国家新环保法2015年1月1日已全面实施,宁钢除尘环保达标排放形势严峻,现有指标与新标准要求存在较大的差距。铁水倒罐和精炼炉除尘系统改造是宁钢的环保工程项目之一,倒罐和精炼炉除尘系统经改造后除尘器出口颗粒物排放浓度由30 mg/m^3下降至15 mg/m^3以下,以满足国家新环保法排放要求。
the National Environmental Protection Law has been fully implemented since May 1st 2015,Ningbo Steel is facing a tough situation of reaching the emmission standard of bag filter. The current filter emmision still has a big gap between the new reqiurement. The iron floe backward de-dusting system revamping is one of the environmental protection projects of Ningbo Steel. The emmission of the filter outlet must be lower from 30 mg/Nm^3 to 15 mg/Nm^3,to achieve the new standard.
