1、脈沖(chong)布(bu)袋除塵器(qi)的(de)清(qing)(qing)灰(hui)(hui)周(zhou)(zhou)期和(he)清(qing)(qing)灰(hui)(hui)時(shi)(shi)間(jian)是確(que)定(ding)捕(bu)集性能(neng)(neng)和(he)運行狀態(tai)的(de)重要因素。清(qing)(qing)灰(hui)(hui)周(zhou)(zhou)期、清(qing)(qing)灰(hui)(hui)時(shi)(shi)間(jian)與所采(cai)取(qu)的(de)的(de)清(qing)(qing)灰(hui)(hui)方式和(he)處理對象的(de)性質等因素有關，所以(yi)_對粉塵性質、含(han)塵濃度等進行檢(jian)測，并且進行必要的(de)檢(jian)測之后再確(que)定(ding)。清(qing)(qing)灰(hui)(hui)周(zhou)(zhou)期和(he)清(qing)(qing)灰(hui)(hui)時(shi)(shi)間(jian)的(de)確(que)定(ding)原則，考(kao)慮的(de)是能(neng)(neng)在(zai)脈沖(chong)布(bu)袋除塵器(qi)布(bu)袋上殘留下一次附著層，以(yi)確(que)保有效清(qing)(qing)灰(hui)(hui)的(de)_少時(shi)(shi)間(jian)，合理的(de)清(qing)(qing)灰(hui)(hui)周(zhou)(zhou)期。使清(qing)(qing)灰(hui)(hui)周(zhou)(zhou)期盡可能(neng)(neng)的(de)長，清(qing)(qing)灰(hui)(hui)時(shi)(shi)間(jian)短，從(cong)而能(neng)(neng)在(zai)經濟(ji)的(de)除塵設備阻(zu)力條件下運行。
2、因(yin)脈沖(chong)(chong)布(bu)袋除塵(chen)(chen)(chen)(chen)器使用的(de)工況條件不同(tong)(粉塵(chen)(chen)(chen)(chen)含量不同(tong))根據(ju)濾袋外壁沉積(ji)粉塵(chen)(chen)(chen)(chen)厚度(du)的(de)變(bian)化而引起(qi)脈沖(chong)(chong)布(bu)袋除塵(chen)(chen)(chen)(chen)器壓差(cha)值的(de)變(bian)化確(que)定清灰周期。在脈沖(chong)(chong)布(bu)袋除塵(chen)(chen)(chen)(chen)器總進(jin)(jin)出口進(jin)(jin)行壓差(cha)取樣(yang)，當脈沖(chong)(chong)布(bu)袋除塵(chen)(chen)(chen)(chen)器的(de)阻力達到上限值時（一(yi)般設定為1500pa即150mm水柱(zhu)高度(du)）開始清灰，根據(ju)差(cha)壓波動(dong)時間確(que)定合理的(de)噴(pen)吹周期。
3、脈(mo)沖布袋(dai)(dai)(dai)除(chu)塵器電(dian)磁脈(mo)沖閥(fa)(fa)的噴(pen)(pen)吹(chui)(chui)(chui)時(shi)(shi)間(jian)(jian)是電(dian)磁閥(fa)(fa)通電(dian)的時(shi)(shi)間(jian)(jian)。一般認為(wei)噴(pen)(pen)吹(chui)(chui)(chui)時(shi)(shi)間(jian)(jian)越長(chang)，噴(pen)(pen)入(ru)脈(mo)沖布袋(dai)(dai)(dai)除(chu)塵器布袋(dai)(dai)(dai)內的氣(qi)量越多，清灰(hui)效果越好。但噴(pen)(pen)吹(chui)(chui)(chui)時(shi)(shi)間(jian)(jian)增(zeng)(zeng)加(jia)到_值后，對清灰(hui)效果的影響(xiang)并不(bu)明(ming)顯。隨噴(pen)(pen)吹(chui)(chui)(chui)時(shi)(shi)間(jian)(jian)的增(zeng)(zeng)加(jia)，除(chu)塵器壓(ya)降(jiang)(jiang)很快(kuai)下降(jiang)(jiang)，而噴(pen)(pen)吹(chui)(chui)(chui)時(shi)(shi)間(jian)(jian)達到_值時(shi)(shi)，壓(ya)降(jiang)(jiang)下降(jiang)(jiang)很少，噴(pen)(pen)吹(chui)(chui)(chui)氣(qi)量卻成倍增(zeng)(zeng)加(jia)。因此想通過調(diao)節噴(pen)(pen)吹(chui)(chui)(chui)時(shi)(shi)間(jian)(jian)來降(jiang)(jiang)低脈(mo)沖布袋(dai)(dai)(dai)除(chu)塵器的壓(ya)降(jiang)(jiang)是有限的。噴(pen)(pen)吹(chui)(chui)(chui)時(shi)(shi)間(jian)(jian)一般設(she)定為(wei)0.08S。
