摘要
常州市污泥焚烧中心一期工程设计规模400 t/d,设三条生产线。核心技术采用日本搅拌筒式干燥机+双桨叶式干燥机和回旋式焚烧炉,实现全干污泥的入炉稳定焚烧,烟气处理采用“干法脱酸+布袋除尘+湿法洗涤”工艺。臭气处理按源头分级管控、分类收集和多途径处理的原则设计,异味控制效果良好。工程运行稳定良好,整个系统烟气热能回收及污染物控制性能优良。
The design scale of Changzhou sludge incineration center phaseⅠproject is 400 t/d,and there are three production lines.The core technology,namely mixing cylinder dryer,double-paddle dryer and gyratory incinerator,is imported from Japan to achieve stable incineration of completely dry sludge in the furnace.The flue gas is purified by the process of dry deacidification,bag dust removal and wet scrubbing.The odor treatment process is designed according to the principles of source classification control,classified collection and multi-method treatment,and good odor control performance is achieved.The project operates stably,and the whole system has excellent performance of flue gas heat recovery and pollutant control.
