屯昌縣靜電除塵器廠家

靜電除塵器的工作原(yuan)理(li)是利用(yong)高壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流(liu)中的粉塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用(yong)下(xia)與氣(qi)流(liu)分離。負極由(you)不同斷面形狀的金屬導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的(de)(de)(de)性能受粉塵(chen)(chen)性質(zhi)、設備(bei)構(gou)造和煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)阻是評價導電(dian)性的(de)(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)效率有直接的(de)(de)(de)影響。比(bi)電(dian)阻過低，塵(chen)(chen)粒難(nan)以保持在(zai)集(ji)塵(chen)(chen)電(dian)極上，致使(shi)其重返氣(qi)流(liu)。比(bi)電(dian)阻過高(gao)，到(dao)達集(ji)塵(chen)(chen)電(dian)極的(de)(de)(de)塵(chen)(chen)粒電(dian)荷(he)不易放(fang)出(chu)，在(zai)塵(chen)(chen)層之(zhi)間形成電(dian)壓梯度會(hui)產生局部擊穿和放(fang)電(dian)現(xian)象。這些情(qing)況都會(hui)造成除(chu)塵(chen)(chen)效率下降。

簡介

靜電除塵器的電源由控制箱、升壓變壓器和整流器組成。電源輸出的電壓高低對除塵效率也有很大影響。因此，靜電除塵器運行電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)基本(ben)原理(li)是利用(yong)電(dian)(dian)(dian)力捕集(ji)煙(yan)氣中的(de)粉塵(chen)(chen)(chen)(chen)，主要包括以(yi)下四個相互有關的(de)物理(li)過程：（1）氣體的(de)電(dian)(dian)(dian)離。（2）粉塵(chen)(chen)(chen)(chen)的(de)荷電(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)粉塵(chen)(chen)(chen)(chen)向電(dian)(dian)(dian)極移動。（4）荷電(dian)(dian)(dian)粉塵(chen)(chen)(chen)(chen)的(de)捕集(ji)。

荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)捕(bu)集過(guo)程：在(zai)兩個曲(qu)率半徑(jing)相差較大的(de)(de)金屬陽極(ji)和(he)陰極(ji)上(shang)，通過(guo)高壓直(zhi)流電(dian)(dian)(dian)，維持一個足(zu)以使氣(qi)體(ti)(ti)電(dian)(dian)(dian)離的(de)(de)電(dian)(dian)(dian)場，氣(qi)體(ti)(ti)電(dian)(dian)(dian)離后所產生的(de)(de)電(dian)(dian)(dian)子：陰離子和(he)陽離子，吸附在(zai)通過(guo)電(dian)(dian)(dian)場的(de)(de)粉(fen)(fen)塵(chen)上(shang)，使粉(fen)(fen)塵(chen)獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)性不(bu)同的(de)(de)粉(fen)(fen)塵(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)作用(yong)下，分(fen)別向不(bu)同極(ji)性的(de)(de)電(dian)(dian)(dian)極(ji)運動，沉積在(zai)電(dian)(dian)(dian)極(ji)上(shang)，而達到粉(fen)(fen)塵(chen)和(he)氣(qi)體(ti)(ti)分(fen)離的(de)(de)目的(de)(de)。
