id="productID" name="productID" value="491756" /><p>　　造紙廠鍋爐煙氣處理設備是為造紙廠生產中產生的廢氣和廢物而生產的除塵設備。鍋爐是造紙廠生產的心臟，主要動力是每個造紙廠。在造紙廠的生產過程中，會產生樹皮、廢木、黑液等多種廢物。生物質流化床鍋爐燃燒和燃氣鍋爐是目前備受推崇的方法:一方面處理廢物，節省掩埋廢物的人力和空間;另一方面，它產生了大量用于生產的蒸汽，提高了造紙廠的經濟效益，一舉兩得。在以往的環保要求中，對造紙廠氮氧化合物的要求并不高。目前，如何以低成本降低氮氧化合物的排放已經成為造紙企業生產活動的首要任務。因此，科杰環保專門為造紙廠鍋爐設計了這種高效的除塵設備，可以解決造紙廠的環境污染問題。目前已在多家造紙廠投入使用，效果良好。</p><p>　　造紙廠鍋爐煙氣處理設備的工作原理:</p><p>　　含塵氣由下部開口法蘭進入過濾室，粗顆粒直接落入塵倉內。含塵氣體由濾袋過濾，灰塵留在袋表，凈氣通過袋口進入凈氣室，風扇排入大氣。隨著濾袋表面塵埃不斷增加，程序控制器開始工作，逐個開啟脈沖閥，使壓縮空氣通過噴嘴，使濾袋猛然膨脹。逆流作用下，袋體表面的塵埃迅速脫離濾袋，落入灰倉，由卸灰閥排出。隨著過濾條件的進行，濾袋上的灰塵越積越多。當設備阻力達到限定阻力值(一般設定為1500Pa)時，清灰控制裝置根據差壓設定值或清灰時間設定值自動關閉一室離線閥，然后按設定程序打開電控脈沖閥進行停風吹風，利用壓縮空氣瞬間吹風增加濾袋內的壓力，將濾袋上的灰塵抖落(即使是粘稠的灰塵也能清除)到灰斗中，由排灰機構排出。由于設備分為幾個箱區，上述過程是逐箱進行的。一箱區域清灰后，其余箱區仍正常運行，機組連續運轉。要想處理高濃度粉塵，關鍵是強除塵時間_短(每次清灰每次需要0.1-0.2秒)。本實用新型除塵效率高，占地面積小，運行穩定，性能可靠，維修方便。</p><p>　　造紙廠除塵器的檢查和維護:</p><p>　　造紙廠鍋爐煙氣處理設備在修理機箱內部時，需要選擇一些_的涂料，以防腐蝕。一般情況下，由于凈化氣體多為酸性，環氧樹脂耐酸涂料較多。箱體縫隙通常包括橡膠墊、橡膠墊、石棉墊等。，以防止氣體泄漏。隨著時間的延長，一些墊片會老化變形，損壞脫落，導致漏風加重。維修時，發現上述表象應認真對待，或更換，或堵漏，盡量防止漏風。對于現有的堵漏材料猜測，環氧樹脂和防漏膠泥都是較好的數據，如因粉塵沖刷而形成孔洞則要補焊。</p><p>　　在我國空氣污染日益嚴重的情況下，鍋爐排放的煙氣成為環保部門控制的重點，排放標準不斷提高。為了達到規定的排放，大多數鍋爐用戶選擇鍋爐除塵器。為了_鍋爐除塵器的正常運行，我們應該經常檢查和維護鍋爐除塵器。</p><p>　　檢查鍋爐除塵器積灰情況。</p><p>　　1.布袋的壓力取決于過濾布袋的材料和厚度。新安裝的布袋通風能力強，壓力降低。時間長了，壓降會增加。在使用過程中，應正確選擇清灰時間和頻率。</p><p>　　2.生產過程中注意觀察鍋爐袋式除塵器的U型壓力計。U型壓力計充滿相應的液體(一般用水調色)，兩端通過管道連接到袋式過濾器的外部和內部，以檢測袋式過濾器的壓降。</p><p>　　3.壓差大表示除塵器布袋過濾器積灰堵塞嚴敢，需要清洗布袋或更換布袋。</p><p>　　4.U型壓力計兩側水柱高度差_為布袋壓差，1mm水柱高度表示壓差為10Pa。</p><p>　　(二)更換鍋爐除塵器除塵設備過濾器。</p><p>　　一、故障判斷。</p><p>　　鍋爐除塵器使用時間長，布袋容易板結。通過檢查u型壓力計，可以判斷其板結情況，決定是否維護或更換布袋。</p><p>　　二、除塵設備布袋的維護和更換。</p><p>　　1.關閉引風機電源和壓縮空氣閥。</p><p>　　2.打開鍋爐除塵器的檢查門，拆下脈沖噴射管，拆下布袋骨架的緊固壓片和螺釘(注意:零件不要掉入除塵器內部，否則容易損壞除塵器的除塵系統)，逐一取出布袋。</p><p>　　3.將布袋從骨架上取下，用于縮空氣吹干凈，如果布袋板結嚴審，清洗不干凈，則更換相同型號的布袋。</p><p>　　4.檢查布袋骨架是否損壞或變形，校正或更換。</p><p>　　5.安裝后，關閉除塵器門，打開壓縮空氣閥和電源，檢查啟動是否正常。</p><p>　　造紙廠鍋爐除塵設備的特點:</p><p>　　1.采用脈沖噴吹除塵技術，不需預除塵設備，除塵能力強，可一次性處理1000mg/m3的煙塵，排放小于50mg/m3，除塵效率高，排放濃度低，漏風系數小，能耗低，鋼耗少，占地面積小，運行穩定可靠，經濟效益好。</p><p>　　2.箱體密封性好，密封性好，檢查門采用優質的密封性，生產過程采用煤油檢漏，漏風率低。</p><p>　　3.進出口風道緊湊，裝置均勻，氣流阻力小。</p><p>　　采用分室停脈沖清灰，清灰周期長，消耗低，可成倍延長濾袋及脈沖閥的使用壽命。</p><p>　　5.可不停機換袋，維修不影響設備正常運行。</p><p>　　6.采用上部抽袋方式，_換袋操作。</p><p
