XDCD型低壓脈沖袋式除塵器是一種采用脈沖清灰方式的小型脈沖袋式除塵器,它具有結構緊湊,清灰方式簡單可靠,更換濾袋方便,收塵效率高等優點,廣泛應用于冶金、化工、建材等工礦企業。
工作原理
含(han)塵(chen)氣(qi)(qi)體(ti)(ti)由(you)進(jin)氣(qi)(qi)口進(jin)入箱(xiang)(xiang)體(ti)(ti),通(tong)過(guo)(guo)(guo)濾袋得以凈化,凈氣(qi)(qi)經(jing)文(wen)氏管進(jin)入上(shang)箱(xiang)(xiang)體(ti)(ti),從排氣(qi)(qi)口排出(chu),濾袋外表面粉塵(chen)不斷增加,使除(chu)塵(chen)器(qi)阻力增大,為(wei)(wei)是設備阻力維持在_范(fan)圍,要_濾袋表面的灰(hui)(hui)(hui)塵(chen),清(qing)灰(hui)(hui)(hui)時(shi)(shi)由(you)控制儀(yi)定期(qi)(qi)順(shun)序觸發各控制閥,開啟(qi)電磁脈(mo)沖(chong)(chong)閥,使氣(qi)(qi)包內(nei)壓縮(suo)空(kong)氣(qi)(qi)由(you)噴(pen)(pen)吹管上(shang)的噴(pen)(pen)追噴(pen)(pen)出(chu)(一次風),通(tong)過(guo)(guo)(guo)文(wen)氏管誘(you)導數倍(bei)于一次風的周(zhou)圍空(kong)氣(qi)(qi)(二次風)進(jin)入濾袋,在瞬間(jian)產生(sheng)振(zhen)動(dong)波(bo)與(yu)逆(ni)向(xiang)氣(qi)(qi)流,抖(dou)下粉塵(chen),落(luo)入下箱(xiang)(xiang)體(ti)(ti),經(jing)卸灰(hui)(hui)(hui)閥排出(chu)機(ji)體(ti)(ti)。在清(qing)灰(hui)(hui)(hui)過(guo)(guo)(guo)程中(zhong),每次噴(pen)(pen)吹的時(shi)(shi)間(jian)稱(cheng)脈(mo)沖(chong)(chong)寬度,一般僅0.1-0.2秒,全部濾袋完成一個清(qing)灰(hui)(hui)(hui)循環(huan)的時(shi)(shi)間(jian)稱(cheng)為(wei)(wei)脈(mo)沖(chong)(chong)周(zhou)期(qi)(qi)。
