摘　　要：孟加拉国达卡市Dasherkandi(达舍尔甘地)污泥干化焚烧工程,采用“污泥喷雾干化+回转窑焚烧”工艺,设置2座300 t/d的喷雾干化塔及2台■3.7 m×16 m回转窑,烟气净化采用“旋风除尘器-活性炭喷射吸附-布袋除尘器-臭氧除臭-三级脱酸喷淋塔”工艺流程,以达到排放要求。项目运行结果表明,烟气指标低于排放限值,灰渣属于一般固废,用于制砖或路基材料。“Sludge spray drying+Rotary kiln incineration”process were used in the sludge drying and incineration project at Dasherkandi in Dhaka of Bangladesh and is equipped with two 300 t/d spray drying towers and two■3.7 m×16 m rotary kilns.The flue gas purification system consists of cyclone dust separator,activated carbon adsorption,bag filter,ozone deodorization and wet deacidification,and the exhaust is required to meet the exhaust standard.The operation results of the project showed that the flue gas emission index lower than the discharge limit.The slag are general solid wastes,which are used as brick making or road foundation materials for recycling.
