脈沖除塵器設備,中央除塵設備工程-東莞市龍記環?？萍加邢薰?/title> <meta name="description" content="工作原理1. 脈沖除塵器設備是指通過噴吹壓縮空氣的方法除掉過濾介質(布袋或濾筒)上附著的粉塵。2. 根據除塵器設備的大小可能有幾組脈沖閥，由脈沖控制儀或PLC控制，每次開一組脈沖閥來除去它所控制的那部分布袋或濾筒的灰塵，而其他的布袋或濾筒正常工作，隔一段時間后下一組脈沖閥打開，清理下一部分除塵器由灰斗、上箱體、中箱體、下箱體等部分組成，上、中、下箱體為分室結構。3. 工作時，含塵氣體由進風道進入灰" /> <meta name="keywords"

style="font-size:15px;">產品概述</span></span></div> <p><span style="font-size: 16px;">工作原理</span></p><p><span style="font-size: 16px;">1. 脈沖除塵器設備是指通過噴吹壓縮空氣的方法除掉過濾介質(布袋或濾筒)上附著的粉塵。</span></p><p><span style="font-size: 16px;">2. 根據除塵器設備的大小可能有幾組脈沖閥，由脈沖控制儀或PLC控制，每次開一組脈沖閥來除去它所控制的那部分布袋或濾筒的灰塵，而其他的布袋或濾筒正常工作，隔一段時間后下一組脈沖閥打開，清理下一部分除塵器由灰斗、上箱體、中箱體、下箱體等部分組成，</span></p><p><span style="font-size: 16px;">上、中、下箱體為分室結構。</span></p><p><span style="font-size: 16px;">3. 工作時，含塵氣體由進風道進入灰斗，粗塵粒直接落入灰斗底部，細塵粒隨氣流轉折向上進入中、下箱體，粉塵積附在濾袋外表面，過濾后的氣體進入上箱體至凈氣集合管-排風道，經排風機排至大氣。</span></p><p><span style="font-size: 16px;">4. 清灰過程是先切斷該室的凈氣出口風道，使該室的布袋處于無氣流通過的狀態(分室停風清灰)。然后開啟脈沖閥用壓縮空氣進行脈沖噴吹清灰，切斷閥關閉時間足以保證在噴吹后從濾袋上剝離的粉塵沉降至灰斗，避免了粉塵在脫離濾袋表面后又隨氣流附集到相鄰</span><span style="font-size: 16px;">濾袋表面的現象，使濾袋清灰徹底，并由可編程序控制儀對排氣閥、脈沖閥及卸灰閥等進行全自動控制。</span></p><p><span style="font-size: 16px;">5. 含塵氣體由進風口進入，經過灰斗時，氣體中部分大顆粒粉塵受慣性力和重力作用被分離出來，直接落入灰斗底部。含塵氣體通過灰斗后進入中箱體的濾袋過濾區，氣體穿過濾袋，粉塵被阻留在濾袋外表面，凈化后的氣體經濾袋口進入上箱體后，再由出風口排出。</span></p><p><span style="font-size: 16px;">應用范圍：電石爐除塵、鋁制品廠、鋼鐵廠除塵、垃圾焚燒除塵、水泥廠除塵、冶煉除塵、燃煤鍋爐及電廠除塵、其應用領域以高溫、較大煙氣量為特色。</span></p><p><span style="font-size: 16px;"><br/></span></p><p style="text-align: center;"><img
