【正文】 本科畢業(yè)設計（論文） 250 噸 /天印染污泥干化及焚燒處理 工藝設計 學 院 環(huán)境科學與工程 專 業(yè) 環(huán)境工程 設計總說明 隨著印染行業(yè)蓬勃發(fā)展，我國對印染廢水處理力度在不斷加大，每天處理污水產(chǎn)生相應大量污泥 ,污泥量日益增加，產(chǎn)生的污泥的組成成分日益復雜，如處理不 當，必然會對自然環(huán)境造成二次污染，存在比較嚴重的環(huán)境安全隱患。 本設計要求處理 250 噸 /天的印染污泥 ，原污泥為經(jīng)過板框壓濾機壓濾過的含水率約82%的濕污泥。針對印染污泥的特點， 結(jié) 合國外處理污泥的成功經(jīng)驗以及國內(nèi)對印染污泥的成熟工藝，決定選用先干化后焚燒的工藝。該工藝具有 工藝成熟、穩(wěn)定、節(jié)能、占地少、效率高 等優(yōu)點?；竟に嚵鞒虨椋簝δ嗍?→回轉(zhuǎn)烘干機 →制磚機 →焚燒爐 →爐渣、煤灰等 回收。 本設計所用的主要設備有 28m 型回轉(zhuǎn)烘干機、 AB200 型焚燒爐、 QTY815型 砌塊成型機、 ppw647 脈沖布袋收塵器、 16m脫硫塔、 LXT5 型活性炭吸附塔。工程總投資為 1305 萬元，每年的總運行費用為 萬元。 關鍵詞： 印染污泥 干化 焚燒 回收利 用 Design illuminate With printing and dyeing industry vigorous development, the printing and dyeing wastewater treatment in growing, every day to produce large amounts of sewage sludge, the sludge quantity increasing, the ponents of sludge produced by the increasingly plex, such as improper handling, is bound to cause secondary pollution to the natural environment, there are serious environmental safety hidden trouble. 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 設計名稱 .......................................................... 1 設計要求 .......................................................... 1 處理處置的一般要求 ................................................ 1 2 設計背景 .............................................................. 3 國內(nèi)外污泥處理處置現(xiàn)狀 ............................................ 3 項目意義 .......................................................... 4 印染污泥的特點 .................................................... 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 設計范圍、依據(jù)及原則 .................................................. 8 設計范圍 .......................................................... 8 設計依據(jù) .......................................................... 8 國家法律、法規(guī)及政策 ........................................... 8 地方法規(guī)及政策 ................................................. 9 技術規(guī)范 和行業(yè)標準 ............................................. 9 3 設計原則 ........................................................ 10 4 工藝流程及說明 ....................................................... 11 5 設計內(nèi)容 ............................................................. 13 廠址 ............................................................. 13 總圖布置 ...................................................... 13 廠區(qū)道路和運輸 ................................................ 13 結(jié)構設計 ...................................................... 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 干化設備 ...................................................... 16 選型計算 ...................................................... 21 焚燒工藝 ......................................................... 23 焚燒設備 ...................................................... 24 工藝設計 ...................................................... 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 土建及設備投資概算 ............................................... 35 其他費用部分 ..................................................... 37 管理費用 ......................................................... 37 預備費用 ......................................................... 37 工程總投資 ....................................................... 38 運行費用概算 ..................................................... 38 7 勞動保護、安全生產(chǎn)及消防 ............................................. 40 勞動保護與安全生產(chǎn) ............................................... 40 消防 ............................................................. 40 8 構筑物一覽表 ......................................................... 42 9 主要設備一覽表 ....................................................... 43 結(jié) 論 ................................................................... 44 參考文獻 ................................................................ 45 致謝 ................................................................
