發布時間：2019年11月12日</div> </div> <div class="JSX_10"> <div id="Z_12_NY_J"> <p>　　用在燃柴鍋爐上，設施裝好后運行3個月布袋堵死變形，當初用的是耐高溫METAMAX(美塔斯)針刺過濾氈<strong><a class="insidelink" href="http://www.bonweexpo.com" title="除塵器濾袋">除塵器濾袋</a></strong>，經鑒定是該布袋需要長期保持60°以上溫度防潮，系統沒設計有保溫設施濾袋受潮后無法再正常使用。以上是個客戶針對于他們安裝的脈沖除塵器在使用過程中提出的問題，首先得要找到<strong>除塵器濾袋</strong>被堵死的原因分析出原因才會找到解決辦法。針對于脈沖除塵器堵袋現象不外乎是粉塵濕度太大，粉塵又潮又細，或者是粉塵溫度過高。</p> <p>　　其實這也是<strong>脈沖除塵器</strong>應用中常見問題，碩航環保技術就這樣的問題給出以下幾點建議：</p> <p>　　1.清灰程序更改：因為離線可以清灰，在線不行，而且打開觀察孔也無粉塵，說明布袋已經堵死，風機抽不上力。所以建議把清灰程序作更改，在脈沖控制儀上將脈沖間隔調小、脈沖寬度調大、循環間隔調小。</p> <p>　　2.濾袋材質：因為沒有保溫所以濾袋的防水性能很重要，表面覆層PTFE膜效果或好些（雖然你說后選的PPS袋子已經防水了）</p> <p>　　3.還是建議給氣箱脈沖除塵器殼體上加保溫層，考慮到除塵器是安裝在室外，冬天溫差很大，煙氣溫度很容易低于露點，那樣對濾袋的過濾性能影響很大，而且在這種情況下一旦堵死濾袋幾乎100%報廢。</p> <p>　　最后說點題外話，使用柴禾作燃料的鍋爐，其粉塵粒徑很細很細（墨粉），加上不保溫，所以除塵器錐體料斗上一定要加震擊器。</p> </div> <div class="CENTER_HUI_XU YIN_C">  <div id="bdshare" class="bdshare_t bds_tools_32 get-codes-bdshare"> <a
