考虑功能的污泥资源化关键装置的构造设计

Construction Design of Key Equipment in Resource Utilization of Sewage Sludge

为解决城市生活污水处理后的副产品污泥的二次污染问题,提出研制将有害的污泥变成有用资源的机械装置。基于污泥脱水后与煤粉颗粒混合与成型形成可燃烧燃料的功能规划,在研究分析机构混合送进腔型和湿固体颗粒体物料受力运动之间的相互牵连关系的基础上,以进出物料总量的平衡和湿固体颗粒体物料在机构中充分混合的运动特性为理论依据,建立了以曲线外壁、变螺距螺旋叶片腔型的结构模型。经试验验证,获得污泥资源化关键装置结构模型的参数与约束关系,由此为自主研制开发新型高效的现代污水处理后污泥资源化装置的关键设备提供理论基础。

To solve the problem of secondary pollution from sludge made by treated sanitary waste, this paper proposes to design mechanic equipment to develop sludge into usable resource. Based on the fact that dewatering sludge mixed with buggy will become fuel, it analyzes the concern of automatic mix feeder and wetted rigid granules when they stressed, the wet solid particles in the body material motion characteristics in an organization full mixed theoretical basis for the establishment of a curved outer wall, the variable pitch helical blade cavity structure model by experimental verification. This paper sets up the parameter of corn equipment for disposal trend of sewage sludge which is tested by experiment, and provides theoretical principle for developing corn equipment of treated sanitary waste.
