摘要:以鄂州市污泥碳化項(xiàng)目為例，介紹了連續(xù)高速碳化技術(shù)的原理、工藝設(shè)計(jì)、處理效果及運(yùn)行管理經(jīng)驗(yàn)。該工藝分為污泥接收、儲存、干化、碳化、粉塵收集、熱量回收、尾氣處理和碳化產(chǎn)品冷卻及儲存共7個單元，通過干餾氣燃燒釋放850 ℃高溫?zé)煔庾鳛闊嵩催M(jìn)行干化，可實(shí)現(xiàn)85%的污泥減量化率，產(chǎn)品碳化物可實(shí)現(xiàn)制磚資源化利用；碳化系統(tǒng)運(yùn)行中不僅提供自身的能量，還可以輸出多余能量供給干燥段，降低了污泥處理對傳統(tǒng)能源的依賴度；系統(tǒng)設(shè)計(jì)時充分考慮了調(diào)節(jié)能力，設(shè)置合理冗余量并采用合適的污泥輸送方式等以保證運(yùn)行順暢，在進(jìn)泥含水率波動（80%~85%）和有機(jī)質(zhì)含量不斷提升的情況下均可實(shí)現(xiàn)穩(wěn)定運(yùn)行，具有良好的適應(yīng)和調(diào)整能力，為我國解決市政污水廠污泥問題提供了新思路和全鏈條實(shí)證示范。
Abstract:Taking the Ezhou sludge carbonization project as an example, this paper expounds on the principle, process design, treatment effect, and operation management experience of continuous high-speed carbonization technology. The process is divided into 7 units including sludge receiving, storage, drying, carbonization, dust collection, heat recovery, tail gas treatment, carbonized product cooling and storage. The 850 ℃ high-temperature flue gas released by the combustion of retort gas is used as the heat source for drying, which can reduce sludge by 85%, and the product carbide can be used as a resource for making brick. The carbonation system can provide not only its own energy, but also excess energy for the drying section, reducing the dependence of sludge treatment on traditional energy. The system design fully considers the regulation capacity, sets reasonable redundancy and adopts appropriate sludge transportation mode to ensure smooth operation. It can achieve stable operation under the condition of fluctuation of sludge moisture content (80%-85%) and continuous improvement of organic matter. It has good adaptability and regulation capacity, and provides a new idea and full chain empirical study for solving the sludge problem of municipal sewage plants in China.
