In this design, projects required to treat 250 tons/day printing and dyeing sludge. Moisture content of the original sludge， which has been pressed by the frame filter， is approximately 82%. Aiming at the characteristic of dyeing sludge, and in the light of the successful experience of external treatment of dyeing sludge and mature technology of internal treatment of that, we select drying and incineration technology. Such a technology has the advantage of mature, stable, energysaving, small footprint and high efficiency. Basic process is: Stored mud room → Rotary dryer brick machine → Incinerator slag → Ash and other recycled. The main equipment used in the design is 28m Rotary Dryer, AB200 type incinerator, QTY815 block making machine, ppw647 Pulse bag filter, 16m desulfurization tower, LXT5type activated carbon adsorption tower. The total investment is million yuan, the total annual operating cost is 12,643,400 yuan Keywords： dyeing sludge mummification incineration recycle 目錄 1 概述 .................................................................. 1 設(shè)計(jì)名稱 .......................................................... 1 設(shè)計(jì)要求 .......................................................... 1 處理處置的一般要求 ................................................ 1 2 設(shè)計(jì)背景 .............................................................. 3 國內(nèi)外污泥處理處置現(xiàn)狀 ............................................ 3 項(xiàng)目意義 .......................................................... 4 印染污泥的特點(diǎn) .................................................... 4 印染污泥適用處理方法 .............................................. 4 印染污泥穩(wěn)定化方法 ............................................. 5 印染污泥的無害化方法 ........................................... 5 印染污泥的最終處置 ............................................. 6 3 設(shè)計(jì)范圍、依據(jù)及原則 .................................................. 8 設(shè)計(jì)范圍 .......................................................... 8 設(shè)計(jì)依據(jù) .......................................................... 8 國家法律、法規(guī)及政策 ........................................... 8 地方法規(guī)及政策 ................................................. 9 技術(shù)規(guī)范 和行業(yè)標(biāo)準(zhǔn) ............................................. 9 3 設(shè)計(jì)原則 ........................................................ 10 4 工藝流程及說明 ....................................................... 11 5 設(shè)計(jì)內(nèi)容 ............................................................. 13 廠址 ............................................................. 13 總圖布置 ...................................................... 13 廠區(qū)道路和運(yùn)輸 ................................................ 13 結(jié)構(gòu)設(shè)計(jì) ...................................................... 13 廠區(qū)道路、大門、圍墻 .......................................... 14 干化工藝 ......................................................... 14 干化過程 ...................................................... 14 加熱方式 ...................................................... 14 污泥干化的熱源 ................................................ 15 污泥干化的系統(tǒng)組成： .......................................... 16 干化設(shè)備 ...................................................... 16 選型計(jì)算 ...................................................... 21 焚燒工藝 ......................................................... 23 焚燒設(shè)備 ...................................................... 24 工藝設(shè)計(jì) ...................................................... 25 煙氣處理工藝 ..................................................... 27 除塵系統(tǒng) ...................................................... 28 雙堿法脫硫 .................................................... 30 活性炭吸附法脫氮 .............................................. 32 灰渣處理系統(tǒng) ..................................................... 33 6 成本概算 ............................................................. 34 勞動定員 ......................................................... 34 土建及設(shè)備投資概算 ............................................... 35 其他費(fèi)用部分 ..................................................... 37 管理費(fèi)用 ......................................................... 37 預(yù)備費(fèi)用 ......................................................... 37 工程總投資 ....................................................... 38 運(yùn)行費(fèi)用概算 ..................................................... 38 7 勞動保護(hù)、安全生產(chǎn)及消防 ............................................. 40 勞動保護(hù)與安全生產(chǎn) ............................................... 40 消防 ............................................................. 40 8 構(gòu)筑物一覽表 ......................................................... 42 9 主要設(shè)備一覽表 ....................................................... 43 結(jié) 論 ................................................................... 44 參考文獻(xiàn) ......................................
