- Discussion and Summary on the Design of Sludge Dewatering, Pumping and Storage System
摘要:- 污泥脫水、輸送及儲存系統(tǒng)是污泥處理處置工程的重要組成部分，以南寧某項目為例，介紹了污泥脫水工藝、進(jìn)泥設(shè)備、加藥系統(tǒng)及
泥水分離閥的設(shè)計及優(yōu)化建議；介紹了污泥輸送螺旋、緩存料斗及料位檢測的工程應(yīng)用特點，提出一體化破拱裝置，詳述污泥輸送泵及其故障處理方式；介紹了污泥儲存系統(tǒng)的管道、入料口的設(shè)計要點，滑架破拱裝置的設(shè)計優(yōu)化及其液壓系統(tǒng)熱平衡分析等。該項目投入運營后，脫水污泥含水率降至80%，污泥的日輸送量達(dá)到66.85 m3/d，污泥儲存系統(tǒng)儲存量達(dá)到200 m3，實現(xiàn)了污泥的減量化生產(chǎn)。最后對該工程進(jìn)行技術(shù)經(jīng)濟分析，為同類項目提供參考。
Abstract:- The systems of sludge dewatering, pumping and storage are important for sludge treatment and disposal. The design and optimization suggestion of dewatering process, sludge feeding equipment, dosing system and sludge-water separation valve were introduced through a project of sludge treatment and disposal in Nanning. As to the sludge pumping system, the technical characteristics of screw conveyor, sludge bin and material level detection were also discussed. Furthermore, the integrated arch breaker device were put forward, and the sludge pumping features and its pumping failure-solution were described in details. With regard to the sludge storage system， the design points of piping and feeding-inlet, the optimization of arch breaker device and its heat balance calculation of the hydraulically-driven system were analyzed. Since the project was put into operation, the water content of sludge was decreased to 80%, the daily transportation capacity of sludge reached 66.85 m3/d and its sludge storage capacity was more than 200 m3. The sludge reduction was realized. Finally, the technoeconomic analysis was conducted, which could provide reference for the similar projects.
