污泥脫水機工作原理
簡介
污泥脫水機工作原理屬于螺旋壓榨脫水機，可以減少沉淀池及污泥濃縮池，節約污水站建設成 本。
巧妙運用自動更新濾餅過濾技術代替了傳統濾篩過濾，自身更新濾餅過濾技術確保脫水機連續穩定的泥水分離效果，通過螺桿直徑和螺距變化產生的強大擠壓力，以及游動環與固定環之間的微小縫隙，實現對污泥進行擠壓脫水，是一種新型的固液分離設備。
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.
工藝流程
工藝流程說明
1、通過絮凝實驗，確定匹配的絮凝劑種類和投加比例。如果需要用兩種絮凝劑才能有效絮凝的，建議選擇帶有兩個絮凝混合槽的脫水機。污泥池內要設置攪拌裝置，脫水機在運行之前和運行過程中，要持續攪拌污泥，保證污泥濃度的相對穩定。
2、運行MDS313污泥脫水機之前，應先用泡藥裝置泡制好絮凝劑溶液。其中高分子絮凝劑的正常的稀釋倍數為500-1000倍。污泥通過污泥輸送泵，泡制好的絮凝劑通過加藥泵，按照相應的比例同時投加到絮凝混合槽內，通過攪拌機進行充分混合形成礬花，在濃縮部進行重力濃縮，濾液從濃縮部的濾縫中排出。濾液含固量低，直接回流到原水池。
3、濃縮后的污泥沿著螺旋軸向前推進，在各種合力的作用下在脫水部充分脫水。脫水部的濾液含固量較高，可回流到絮凝混合槽再次脫水。
4、脫水后的泥餅從泥餅排出口排出，直接或通過無軸螺旋輸送機送至運泥車，進行再利用。
構造原理
的主體是由多重固定環和游動環構成，螺旋軸貫穿其中形成的過濾裝置.前段為濃縮部，后段為脫水部，將污泥的濃縮和壓榨脫水工作在一筒內完成，以*微妙的濾體模式取代了傳統的濾布和離心的過濾方式。
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.
脫水原理
污泥在濃縮部經過重力濃縮后,被運輸到脫水部,在前進的過程中隨著濾縫及螺距的逐漸變小,以及背壓板的阻擋作用下,產生*的內壓,容積不斷縮小,達到充分脫水的目的。
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.
優勢

污泥脫水的利器！
- 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
*的動、靜環濾縫結構使得設備不易堵塞，無需為防止濾縫堵塞而進行大量清洗，*減少沖洗用水量，減少內循環負擔，解決了傳統脫水設備堵塞給企業帶來的煩惱。
- 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) 連續自動運行 疊螺污泥脫水機從抽出污泥、注入藥液、排出污泥餅 
均采用自動控制，通過電控柜，與泡藥機、進泥泵、加藥泵等進行聯動，不需人員操作設備，運行不會發生堵塞、濾帶走偏或其他影響工藝安全的現象，日常保養維護簡便，24小時可以連續無人運行。*次實現了真正意義上污泥脫水連續全自動運行。
- 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) 節省運行費用一體化的整體設計，設計緊湊，大幅度節省運行費 用。低速螺旋擠壓技術，使得耗電量大幅度低；設備 
不堵塞，沖洗用水大幅度減少；24小時全自動無人運行，人工費大幅度降低。因此，本設備也真正成為符合國家政策的節能環保新型設備。
- 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) 節省工程投資 疊螺污泥脫水機本身具備污泥濃縮功能，直接處理曝氣池內好氧污泥，不需要濃縮及貯存單元，減少污水處理設施整體的占地空間和建設成本。
- 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.
