沼液污泥固液分离机

沼液污泥固液分离机

 简介

沼液污泥固液分离机属于螺旋压榨脱水机，可以减少沉淀池及污泥浓缩池，节约污水站建设成 本。

沼液污泥固液分离机巧妙运用自动更新滤饼过滤技术代替了传统滤筛过滤，自身更新滤饼过滤技术确保脱水机连续稳定的泥水分离效果，通过螺杆直径和螺距变化产生的强大挤压力，以及游动环与固定环之间的微小缝隙，实现对污泥进行挤压脱水，是一种新型的固液分离设备。

Multi-Disk Screw Press( Hereinafter referred as MDS ) belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. MDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

• Can be widely used in municipal sewage, food, slaughtering breeding, printing and dyeing, oil chemical industry, paper making, leather, pharmaceutical and other industries of sludge dewatering;
• Exclusive pre-concentration design, applicable sludge concentration of 2000mg/L-50000mg/L;
• Due to the innovation of the structure design, it is highly suitable to various high and low concentration sludge, most especially for the oily ones.

2) 不易堵塞

独特的动、静环滤缝结构使得设备不易堵塞，无需为防止滤缝堵塞而进行大量清洗，彻底减少冲洗用水量，减少内循环负担，解决了传统脱水设备堵塞给企业带来的烦恼。

•   Due to rotation of helical axis, the moving rings begin detaching from the fixed rings while continuously starting the self-cleaning process.  As a result, the ubiquitous clogging is avoided. Therefore, it can handle oily sludge without any trouble while separating the water from the sludge easily. In addition, there is no need to add large quantity of flushing water and there is no odor and no secondary pollution during the dewatering process.

3) 连续自动运行
 叠螺污泥脱水机从抽出污泥、注入药液、排出污泥饼  

均采用自动控制，通过电控柜，与泡药机、进泥泵、加药泵等进行联动，不需人员操作设备，运行不会发生堵塞、滤带走偏或其他影响工艺安全的现象，日常保养维护简便，24小时可以连续无人运行。*次实现了真正意义上污泥脱水连续全自动运行。

•  There are no easily blocked pieces such as belt and filtration pore in Multi-Disk Screw Press. Combining with the auto control system, the machine runs very safely and simply and can be programmed according to the requirement of the users. It can operate automatically for 24 hours, unmanned.

4) 节省运行费用
一体化的整体设计，设计紧凑，大幅度节省运行费 用。低速螺旋挤压技术，使得耗电量大幅度低；设备 不堵塞，冲洗用水大幅度减少；24小时全自动无人运行，人工费大幅度降低。因此，本设备也真正成为符合国家政策的节能环保新型设备。

• Multi-Disk Screw Press works by the machine’s internal pressure and needs no large scale integrations like rollers. It saves energy and water and has very minimal noise because of low running speed (2-4 r/min). The average unit power consumption is only 0.1-0.01kwh/kg-DS (1/8 of Belt Press and 1/20 of Centrifuge), and can greatly reduce the running cost of wastewater treatment system.

5) 节省工程投资
 叠螺污泥脱水机本身具备污泥浓缩功能，直接处理曝气池内好氧污泥，不需要浓缩及贮存单元，减少污水处理设施整体的占地空间和建设成本。

• Multi-Disk Screw Press can treat sludge in aeration tank and secondary sedimentation tank without setting sludge thickeners. Therefore, this can decrease the total investment, avoid phosphorus release from the sludge thickeners and sludge storage tanks and enhance phosphorus removal effect of the wastewater treatment system.
• Save construction investments on sludge thickeners and costs on mixers, air compressors, flushing pumps and other auxiliary equipment.
• Occupy smaller space, reducing the construction investment on dewatering room.

 沼液污泥固液分离机

沼液污泥固液分离机的主体是由多重固定环和游动环构成，螺旋轴贯穿其中形成的过滤装置.前段为浓缩部，后段为脱水部，将污泥的浓缩和压榨脱水工作在一筒内完成，以独特微妙的滤体模式取代了传统的滤布和离心的过滤方式。

Layers of the spacers, which are Fixed and Moving Rings, are secured in place by a tie rod. The inner diameters of the Moving Rings are slightly smaller than the outer diameter of the screw and their rings. Mobilized by the screw, it continuously cleans the sludge out of the gaps, therefore, preventing clogging.

 沼液污泥固液分离机

污泥在浓缩部经过重力浓缩后,被运输到脱水部,在前进的过程中随着滤缝及螺距的逐渐变小,以及背压板的阻挡作用下,产生*的内压,容积不断缩小,达到充分脱水的目的。

The initial section of dewatering drum is the Thickening Zone, where the solid-liquid separating process takes place and where the filtrate will also be discharged. The pitch of the screw and the gaps between the rings decrease at the end of dewatering drum, hence increasing its internal pressure. At the end, the End Plate further increases the pressure, so as to discharge dry sludge cake.

  沼液污泥固液分离机工艺流程

沼液污泥固液分离机工艺流程说明

1、通过絮凝实验，确定匹配的絮凝剂种类和投加比例。如果需要用两种絮凝剂才能有效絮凝的，建议选择带有两个絮凝混合槽的脱水机。污泥池内要设置搅拌装置，脱水机在运行之前和运行过程中，要持续搅拌污泥，保证污泥浓度的相对稳定。
2、运行MDS313污泥脱水机之前，应先用泡药装置泡制好絮凝剂溶液。其中高分子絮凝剂的正常的稀释倍数为500-1000倍。污泥通过污泥输送泵，泡制好的絮凝剂通过加药泵，按照相应的比例同时投加到絮凝混合槽内，通过搅拌机进行充分混合形成矾花，在浓缩部进行重力浓缩，滤液从浓缩部的滤缝中排出。滤液含固量低，直接回流到原水池。
3、浓缩后的污泥沿着螺旋轴向前推进，在各种合力的作用下在脱水部充分脱水。脱水部的滤液含固量较高，可回流到絮凝混合槽再次脱水。
4、脱水后的泥饼从泥饼排出口排出，直接或通过无轴螺旋输送机送至运泥车，进行再利用。

Two former digits means the MDS cylinder diameter, the last digit shows the number of the screw shafts, such as MDS 312, it means the MDS cylinder diameter is 310mm, the number of the screw shafts is two.

② Sludge Treatment Capacity=DS Standard Capacity÷Sludge Concentration (DS stands for Dried Sludge, 0% moisture.)

* Throughput of each model is based on sludge cake with 85% water content.

* There is no certain upper limitation on inlet sludge concentration, however, the target sludge must be flowable.

* Throughput of DAF Sludge is based on sludge containing much fat, oil, and grease such as meat processing applications etc.

* Throughput of Mixed Sludge (Primary Sludge and Waste Activated Sludge) and Aerobically Digested Sludge is based on sludge containing more than 30% fiber (200 mesh) against Total Solids.
