Description

一种污泥风干装置
技术领域
本实用新型属于污泥处理设备领域，具体为对污水污泥进行低能耗干燥处理的一种污泥风干装置。
背景技术
在城镇污水处理的过程中会产生大量的污泥，污水处理厂一般仅对其进行浓缩和脱水处理，含水率约80％的脱水污泥通常被外运处理处置。为了有效地实现污泥的减量化和资源化利用，一般会先对脱水污泥进行干燥处理。
国内外常用的污泥干燥工艺主要有流化床干燥、多层圆盘干燥、薄膜干燥、浆叶干燥和带式干燥，它们以直接或间接的方式对脱水污泥进行干燥。在实际的干燥过程中难以避免地会出现以下问题：(1)干燥设备内部元件磨损严重，导致设备的故障率较高：(2)采用中高温干燥，干燥能耗高；(3)干燥后尾气处理工序复杂，费用较高；(4)存在粉尘爆炸和火灾的可能性，具有很高的危险性。
实用新型内容
本实用新型的目的是针对以上所述污泥干燥工艺存在的不足，提供干燥耗能低、尾气污染低、设备投资少、运行稳定和安全性高的一种污泥风干装置。
本实用新型是这样实现的：一种污泥风干装置，包括最少一段风干机构、定量给料机构和除湿加热机构，
所述的风干机构包括主轴、铰刀和电机，电机的输出轴与主轴连接，电机带动主轴慢速转动，铰刀根据污泥的输送方向有规律地安装在主轴上，具有使物料翻动、破碎、移动的功能；定量给料机构与风干机构的始端连接。
所述的风干机构设置有两段，定量给料机构与第一段风干机构的始端连接，第一段风干机构的末端与第二段风干机构的始端连通，在连通处上方设置有出料口，第二段风干机构末端与第一段风干机构始端连通，使第一段风干机构与第二段风干机构形成环路结构。
所述的除湿加热机构包括除湿冷交换器、尾气热交换器、除湿热交换器、空气加热器、风机和制冷压缩机，进风口与除湿冷交换器连接，除湿冷交换器与尾气热交换器连接，尾气热交换器通过鼓风机与除湿热交换器连接，除湿热交换器与空气加热器连接，除湿冷交换器底部设有冷凝水排放管。
所述的除湿加热机构设置在风干机构的上方，空气加热器出口以管道与风干机构进风口连接；风干机构上盖排气口与尾气热交换器列管进口端连接，列管出口端集气室底部设有冷凝水收集管，上部为尾气出口。
所述的定量给料机构包括污泥贮槽和定量螺旋输送机，定量螺旋输送机设置在污泥贮槽的下方。
与现有技术相比，本实用新型具有的优点是：一是动态生产稳定性高，可实现全自动化生产；二是除湿加热机构中的冷、热能回收设置使得干燥效率高、能耗低；三是污泥在干燥装置内的停留时间可调，使得出料含水率可调；四是尾气经冷却排放冷凝水后才排出，降低了尾气处理成本；五是产出的污泥为松散颗粒状，长期存放不会厌氧发臭，更利于污泥的资源化利用。

具体实施方式
以下结合附图和具体实施例对本实用新型一种污泥风干机构进行详细的说明。
一种污泥风干机构，如图1～4所示，包括最少一段风干机构、定量给料机构和除湿加热机构，风干机构包括外壳、主轴、铰刀4和电机，电机的输出轴与主轴连接，电机带动主轴慢速转动，铰刀4根据污泥的输送方向有规律地安装在主轴上，具有使物料翻动、破碎、移动的功能；定量给料机构与风干机构的始端连接。风干机构设置有两段，定量给料机构与第一段风干机构5的始端连接，第一段风干机构5的末端与第二段风干机构8的始端通过连通通道7连通，在连通通道7处上方设置有出料口21，第二段风干机构8末端与第一段风干机构5始端连通，使第一段风干机构5与第二段风干机构8形成环路结构。
定量给料机构由包括污泥贮槽2和定量螺旋输送机3组成，定量螺旋输送机3设置在污泥贮槽2的下方。从进口1进入污泥贮槽2，由定量螺旋输送机3输送进入第一段风干机构5的始端，污泥投加量由定量螺旋输送机3的转速调节，含水率5％～35％的干污泥由风干机构内定量螺旋输送机10输送，干污泥投加量由风干机构内定量螺旋输送机10的转速调节。
除湿加热机构包括除湿冷交换器12、尾气热交换器13、除湿热交换器16、空气加热器17、鼓风机15和制冷压缩机14，进风口11与除湿冷交换器12连接，除湿冷交换器12与尾气热交换器13连接，尾气热交换器13通过鼓风机15与除湿热交换器16连接，在除湿热交换器16上设置有空气加热器17，在除湿冷交换器12底部设有冷凝水排放管22。除湿加热机构设置在第一风干机构5的上方，空气加热器出口以管道19与风干机构侧面或底部的进风口20连接；风干机构上盖排气口与尾气热交换器列管进口端连接，列管出口端集气室底部设有冷凝水收集管，上部为尾气出口。
含水率40％～85％的脱水污泥，从进口1进入污泥贮槽2，由定量螺旋输送机3输送进入第一段风干机构5的始端，污泥投加量由定量螺旋输送机3的转速调节，含水率5％～35％的干污泥由风干机构内定量螺旋输送机10输送来，干污泥投加量由风干机构内定量螺旋输送机10的转速调节；干湿污泥在铰刀4的作用力下一起混合、翻松、前移，第一段风干机构5的主轴转速为0～30转/分可调，此过程中与从进气口20来的除湿热空气进行传热传质作用，污泥中的水分被不断蒸发；至第一段风干机构5末端时，污泥含水率已下降至20％～40％之间，外观呈松散颗粒状。在挤压力的作用下，第一段风干机构5末端的污泥通过连接第一段风干机构5和第二段风干机构的连通通道7进入第二段风干机构8的始端，第二段风干的主轴转速为0～30转/分可调，在第二段风干机构8的料位高于出料口21底部时，污泥则通过出料口21排出污泥产品。进入第二段风干机构8的污泥在铰刀的作用下边翻动边前移，同时与从第二段风干机构8底部上来的除湿热空气进行传热传质作用，污泥中的水分继续被蒸发，至第二段风干机构末端时，污泥含水率已下降至5％～35％，然后通过定量螺旋输送机10输送进入第一段风干机构5的始端，与新进入第一段风干机构5的含水率在40％～85％的脱水污泥混合，进行下一个循环。
在鼓风机15的作用下，空气从除湿加热机构进口11被抽入，在除湿冷交换器12被冷却，冷凝水从空气冷凝水收集管22排出；除湿后的空气进入尾气热交换器13管外，尾气进入尾气热交换器管内，空气与尾气进行间接换热回收尾气中的热量；随后空气进入除湿热交换器16回收除湿系统热量，再进入空气加热器17将温度提高至20～200℃；最后通过通过总管18分配进入连接管道19鼓入第一段风干机构和第二段风干机构中。除湿热空气与污泥进行传热传质，使污泥的水分蒸发；尾气通过干化装置顶部的集气口被收集，在尾气热交换器13管内被冷却，冷凝水从尾气冷凝水收集管24排出，冷却后的尾气从尾气排放管23排出。
上述实施例并非是对本实用新型的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以作出各种变化和变型，因此所有等同的技术方案也应属于本发明的范畴，本实用新型的专利保护范围应由各权利要求限定。
