污泥焚烧无害化处理方案设计

Project design for sludge harmless treatment by incineration

通过对合肥市城市污泥处置现状和污泥特性分析,制定了污泥焚烧无害化处理方案。详细论述了WNS污泥管道输送焚烧技术,介绍了污泥焚烧的燃煤热力发电厂主要工艺设备选型。WNS污泥管道输送系统是一种新型、高效、节能、环保型的污泥输送系统,可将其与改造后的循环流化床锅炉相结合。该方案能满足合肥市城市污泥无害化处理的要求。

Through the analysis on the current status of urban sludge disposal of Hefei city and the sludge characteristics, a scheme for sludge harmless treatment using incineration technique was formulated. The WNS sludge pipeline transportation and incineration technology were elaborated, meanwhile, the selection of main process equipments for sludge incineration in coal-fired power plant were introduced. It was proved that WNS sludge pipeline transportation was a kind of novel, efficient, energy saving, environmental protective system for sludge transportation, and the scheme combining the said system with the modified circulating fluidized bed boiler could meet the requirement of urban sludge harmless treatment of Hefei city.
