摘 要:目前我国已建污泥焚烧项目中烟气的脱酸工艺多采用湿法为主的路线,对于采用“孤岛式”模式建设的项目,脱酸废水实现零排成本较高,湿法为主的脱酸路线运行成本不具有优势。以某“孤岛式”污泥焚烧项目脱酸工艺为研究对象,分析了常用的脱酸工艺特点,同时从脱酸药剂选择、脱酸效率分配、飞灰螯合等方面设定了7个方案,比较了不同工艺组合方案的运行成本,论证了本项目选择脱酸工艺路线的合理性;并结合废水排放、飞灰螯合的可行性提出了污泥焚烧项目烟气脱酸工艺选择的建议,为污泥焚烧新建或工艺改造项目设计提供参考建议。At present,the deacidification process of flue gas of established sludge incineration projects in China mostly adopts the wet process-based route.For the projects constructing in the“isolated island”mode,the cost of zero discharge of deacidification wastewater is high,while the operation cost of the wet-based deacidification route has no advantages.The deacidification process of an“isolated island”sludge incineration project was taken as the research object,the characteristics of the commonly used deacidification process were analyzed.Meanwhile,seven schemes were set up from the aspects of deacidification agent selection,deacidification efficiency allocation,fly ash chelation and so on,in order to contrast the operating cost of different process combination schemes,and demonstrate the rationality of the selection of deacidification process route for this project.Finally,suggestions on the selection of flue gas deacidification process for sludge incineration projects were put forward combined with the feasibility of wastewater discharge and fly ash chelation,which could provide reference suggestions for the design of new sludge incineration or process transformation projects.
