class="ez-toc-section" id="i-2"></span></h2> <p>1、洗滌方式的性能及效率，從數據可看出第二種洗滌方式的處理率較低，必須與其它處理方式結合使用，第三種和第四種洗滌方式的處理率高，但所需的動力也最大，處理小風量的廢氣才經濟，用來處理大風量的工程動力部分投資過大。根據本工程實際情況，單套處理系統風量在25000~38000m3/h左右，屬于稍大風量，本工程擬采用性價比高的第一種技術—噴霧填料吸收塔。<br /> 2、吸收液的選擇，堿性廢氣和含氰廢氣：采用硫酸亞鐵溶液吸收。采用硫酸亞鐵水溶液作為吸收液時，PH保持在弱酸狀態，可以使凈化效率達到90%以上。故將含氰廢氣與NaOH廢氣一并處理。<br /> 3、工藝流程說明，廢氣處理設備的工作原理是將氣體中的污染物質分離出來，轉化為無害物質，以達到凈化氣體的的目的。它屬于微分接觸逆流式，塔體內的填料是氣液雨相接觸的基本構件。它能提供足夠大的表面積，對氣液流動又不致造成過大的阻力。吸收劑是處理廢氣的主要媒體，它的性質和濃度是根據廢氣的性質來選配。廢氣由風管吸入，自下而上穿過填料層；循環吸收劑由塔頂通過霧化液體分布器，形成的水霧勻地噴淋到填料層中，沿著填料層表面向下流動，進入循環水箱。由于上升氣流和下降霧化吸收劑在填料中不斷接觸，上升氣體中流質的濃度愈來愈低，凈化器排出少量沒被吸附、吸收的有害物質及粉塵再經活性炭過濾、吸附，經活性炭吸附后潔凈氣體達標排放。</p> <h2>電鍍廠廢氣處理特點<span class="ez-toc-section" id="i-3"></span></h2> <p>1、本設備可用鋼塑料和玻璃鋼制作，技術先進，運行成本低。<br /> 2、低風阻設計，凈化效率高、能耗低、安全性高、適用面廣。<br /> 3、塔內不帶電設計，安全性高，使用壽命長。<br /> 4、多重凈化，粉塵、油膏攔截率高，針對成分復雜的廢氣，綜合處理能力強。<br /> 5、該設備具有占地面積小、便于維修、附屬設備少、無二次污染等特點。</p> <h2>電鍍廠噴漆廢氣處理排放標準與治理方案<span class="ez-toc-section" id="i-4"></span></h2> <p>1、連續不間斷的處理廢氣，（天燃氣RTO為間歇工作模式）這在垃圾焚燒尾氣，凹版印刷有機廢氣處理應用方面尤為重要。<br /> 2、廣譜性：能夠處理高濃度、成分復雜、易燃易爆及含有大量水分、固態、油狀物的工業廢氣，實現達標排放。<br /> 3、不消耗天然氣，無碳排放問題，沒有閥門等運動部件，能夠無故障，不間斷運行上萬小時。<br /> 4、風阻小，能耗低：處理2萬立方米/小時的燃氣RTO，為克服陶瓷蓄熱體風阻就需要功耗為90千瓦的引風機。</p> <h3>2.1從源頭減少廢氣的產生<span class="ez-toc-section" id="21"></span></h3> <p>1、電鍍前處理的堿洗除油、酸洗去銹或去氧化皮過程中，可在溶液中分別添加堿霧抑制劑和酸霧抑制劑，從而大大減少堿霧和酸霧的逸出。與此同時，還可在各電鍍槽的槽口兩側各增加一塊窄窄的、可活動的擋風板，除可遮蓋陽極掛鉤、陽極板和加熱器而使槽面顯得整潔，更能因可視槽液面積的縮小而增強槽邊的排風效果，從而減少了廢氣對車間環境的污染。<br /> 2、去除鋼鐵件上的氧化皮時，可采用噴丸工藝取代部分化學酸洗或采用無酸酸洗工藝，這樣便可在源頭上大大減少酸性廢氣的產生。<br /> 3、對于銅件，用混合酸(硫酸加硝酸)清洗或用硝酸退鍍時，可通過加入少量尿素來抑制和削減氮氧化物的產生。不提倡單純用硝酸酸洗和退鍍。<br /> 4、在鍍鉻槽中加入少量F-53(全氟烷基醚磺酸鹽)，就可抑制鉻酸霧的產生。若鍍鉻槽中還有聚乙烯或聚氯乙烯空心塑料球漂浮在液面，則抑霧效果會更好。</p> <h2>電鍍廢氣主要有：<span class="ez-toc-section" id="i-5"></span></h2> <p>1、粉塵：主要由噴砂、打磨、拋光等工序產生，含有沙粒、金屬氧化物以及纖維性粉塵。<br /> 2、酸性廢氣：采用鹽酸硫酸等酸性物質進行酸洗拋光工藝產生，有氯化氫、二氧化硫、氟化氫等酸霧，具有強烈的腐蝕性。<br /> 3、堿性廢氣：電鍍過程中使用的氫氧化鈉、碳酸鈣、磷酸鈉等堿性物質，加上加熱工藝產生。<br /> 電鍍廠廢氣主要有以下幾種：<br /> 1、含塵廢氣。主要由噴砂、磨光及拋光等工序產生，含有沙粒、金屬氧化物及纖維粉塵。<br /> 2、酸性廢氣。由于鹽酸、硫酸等酸性物質進行酸洗、出光和化學拋光等工藝所產生，如：氯化氫、二氧化硫、氟化氫、硫化氫及磷酸等氣體和酸霧。<br /> 3、堿性廢氣。由于使用氫氧化鈉、碳酸鈉及磷酸鈉等堿性物質，由于加熱等工藝操作所產生的堿性氣體。<br /> 4、含鉻廢氣。在鍍鉻工藝中產生的鉻酸霧，毒性極大。<br /> 5、含氰廢氣。由氰化電鍍殘生，如氰化鍍銅、鍍鋅及仿金等。</p> <h2>電鍍廠廢氣處理方法有哪些？<span class="ez-toc-section" id="i-6"></span></h2> <p>1、可以將車間內的點收集改為點收集與面收集相結合的方式，即對重點污染物排放處設置存污染廢氣收集裝置，對整個車間還設置面收集，保證車間空氣中的污染物濃度沒有超過限值。<br /> 2、可以綜合酸堿性廢氣、鉻霧、氰化物、氮氧化物等噴淋液的特點，制備出一種能同時吸收所有廢氣的吸收液，或研究一套綜合吸收的工藝流程，保證電鍍生產中所有廢氣都被吸收凈化。<br /> 3、源頭控制，優化電鍍設計工藝流程，減少污染物的排放，并加緊對電鍍污染物進行分析和研究，制定有針對性的廢氣治理技術難題解決方案。<br /> 1、吸附效率高,能力強；<br /> 1、能夠同時處理多種混合有機廢氣；<br /> 2、設備構造緊湊，占地面積小，維護管理簡單，運轉成本低廉；<br /> 3、采用自動化控制運轉設計，操作簡易、安全；</p> <h2>廢氣處理噴淋塔技術特點：<span class="ez-toc-section" id="i-7"></span></h2> <p>1、廢氣治理設備凈化效率高：采用特殊結構的、比表面積大的填料作為傳質和脫水填料；<br /> 2、有機廢氣處理工藝簡潔，安裝方便，維護保養簡單，不需專人看護；<br /> 3、運行費用低，工程造價低，經濟適用；<br /> 4、低噪聲、低能耗、輕巧耐用，外形美觀；</p> <div class='yarpp-related'> <h3>Related posts:</h3><ol> <li><a
