Description

一种移动式污泥脱水设备及其应用 技术领域
本发明涉及一种移动式污泥脱水设备及其应用，属于污泥处理技术领域。
背景技术
近年来，镇村污染防治得到了高度的重视，镇村污水治理市场迅速打开，镇村污水处理项目在各地得到快速发展。
此类污水处理项目涉及大量的镇、村级小型污水处理站，呈现规模小(日处理量一般为200～1000m 3/d)、数量多、站点分散、污泥产生量少的问题，且运营维护过程中，村镇污水厂污泥处理的问题日益突出。传统设计方案是考虑在污水厂区设置污泥储存池，定期使用污泥罐车抽走，外运至集中点处理，但储存池内的污泥含水率一般在95％～99％，污泥外运体积大，导致运输费用高、效率低，且存在污泥二次污染的环境风险；若采取传统污水厂做法，在每个污水处理站点设置固定式污泥脱水***，因单个站点产泥量有限，污泥脱水设备运行不稳定，且项目建设投资大、运行成本高、运营维护难度大。
发明内容
针对现有技术中的问题，本发明提供一种移动式污泥脱水设备及其应用，本发明通过巧妙的设计将污泥调理、脱水、存储集成于一标准集装箱中，具有车载可移动性，能实现“一套设备，多点使用”。

作为优选方案，所述絮凝投药装置内设双格，分别为第一格和第二格，第一格和第二格分别由下方设有孔洞的两隔板和左右两侧侧壁围成，各格内均设有搅拌桨；自动投药装置位于第一格的上方，观察口位于第二格的上方。
作为优选方案，所述絮凝投药装置的前侧壁上部设溢流口，右侧壁下部设排空管。
作为优选方案，所述泥饼衔接斗槽上部设定位置处设有泥位开关，泥位开关与PLC控制柜电性连接，当泥饼衔接斗槽内的脱水污泥的位置高于泥位开关位置时，泥位开关将信号反馈给PLC控制柜，设备自动停止工作。
作为优选方案，输泥管为蛇形管，输泥管的弯头处均设有检查口。
作为优选方案，出泥管和输泥管上均设有用于监测管压的压力表。
作为优选方案，所述污泥储存料仓顶部设有仓顶泥位开关，底部设有仓底泥位开关，仓底泥位开关位于排泥螺杆泵位上方，仓顶泥位开关和仓底泥位开关均与PLC控制柜电性连接，当污泥储存料仓内脱水污泥位置高于仓顶泥位开关或低于仓底泥位开关时，仓顶泥位开关或仓底泥位开关将信号反馈给PLC控制柜，设备自动停止工作。
作为优选方案，所述集装箱内设置有通向絮凝投药装置顶部的爬梯。
作为优选方案，所述集装箱大小采用平板车车载箱体尺寸，采用标准平板车运输。
上述移动式污泥脱水设备在污泥处理上的应用，具体步骤为：采用标准平板车运输集成成套设备的集装箱至村镇污水厂站，在外接水泵的作用下，村镇污水厂站污泥池内的泥水被抽吸至絮凝投药装置中，开启双格内的搅拌桨的同时开启自动投药装置投加污泥调理药剂，泥水通过隔板下方孔洞从第一格进入第二格中，泥水在加药搅拌过程中形成大颗粒絮体，经絮凝后的泥水通过连接管溢流进入叠螺脱水机进行脱水，泥水分离成含水率为80％的脱水污泥和滤液，其中，滤 液进入滤液槽内并经滤液排空管排出，脱水污泥落入泥饼衔接斗槽中，在污泥转移螺杆泵的作用下，脱水污泥经输泥管被输送至污泥储存料仓中存储，存储于污泥储存料仓中的脱水污泥在排泥螺杆泵的作用下经出泥管排出。
从以上描述可以看出，本发明具备以下优点：
(1)本发明装置通过巧妙的设计将污泥调理、脱水、存储集成于一标准集装箱中，并可实现车载可移动性，实现“一套设备，多点使用”。同时，考虑到乡村道路情况较差，大型车辆行驶较为困难，而本套设备标准集装箱体所匹配的平板车对该类道路适应性较强。
(2)传统污泥调理设备需预先将干粉PAM搅拌溶解成液体后再与泥水混合，溶解搅拌所需时间需0.5小时以上。本发明装置絮凝加药装置可实现进泥同时直接投加干粉PAM与泥水混合溶解，搅拌后形成大颗粒絮体，相较传统方式更为省时便捷，且节约了占地。
(3)本发明装置主体污泥脱水设备选择叠螺脱水机，该类设备相较带式、板框等脱水设备噪音小能耗低、体积小、装机功率小，较为匹配村镇污水处理站点面积小、距离住宅近、变压器装机容量小等特点。
(4)本发明装置污泥料仓中部设置了搅拌桨，解决了污泥存储时间长容易板结导致排泥不畅的问题。
(5)就解决村镇污水处理站点污泥处理问题，本套装置相较传统污水厂污泥处理方式大幅节约了投资成本及运行维护成本；同时相较时下较为常用的罐车运输泥水的方式，由于污泥脱水后体积的大幅降低亦大幅降低了运输成本。
