臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥式靜電(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈化法(fa)來收(shou)(shou)捕廢氣(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)(de)凈化工作上(shang)要是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)淀兩個系統來完成的(de)(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)體(ti)進(jin)人氣(qi)刺叭時，含塵(chen)(chen)氣(qi)體(ti)受到氣(qi)流分布板(ban)以及折(zhe)流板(ban)的(de)(de)(de)(de)(de)調整(zheng)后，使氣(qi)流能較均勻地進(jin)人電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴(kuo)大(da)的(de)(de)(de)(de)(de)作用下，氣(qi)流速(su)度(du)迅速(su)降低，其(qi)中有(you)些(xie)較重的(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速(su)度(du)而沉(chen)降下來。進(jin)人電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含塵(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通(tong)人高(gao)壓直流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現(xian)象，使氣(qi)體(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)(de)氣(qi)體(ti)中存(cun)在(zai)大(da)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)(zi)，這些(xie)電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)(zi)與進(jin)人電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)(de)作用下趨向本(ben)設(she)備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采用負高(gao)壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)分別沉(chen)積(ji)在(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)設(she)備陰(yin)陽極(ji)(ji)振打系統的(de)(de)(de)(de)(de)振打，使沉(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人集灰(hui)斗(dou) 通(tong)過(guo)排(pai)灰(hui)裝置放出(chu)，回收(shou)(shou)有(you)物料(liao)，被)凈化的(de)(de)(de)(de)(de)氣(qi)體(ti)排(pai)入大(da)氣(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作原理是(shi)利用高壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流(liu)(liu)中的(de)(de)粉(fen)(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用下與氣(qi)流(liu)(liu)分離(li)。負極(ji)(ji)(ji)(ji)由不(bu)同(tong)斷面形狀的(de)(de)金屬導線(xian)制成(cheng)(cheng)，叫(jiao)(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。正(zheng)極(ji)(ji)(ji)(ji)由不(bu)同(tong)幾何(he)形狀的(de)(de)金屬板制成(cheng)(cheng)，叫(jiao)(jiao)集(ji)(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性能受粉(fen)(fen)塵(chen)(chen)性質、設備(bei)構造和(he)煙氣(qi)流(liu)(liu)速等三個因素的(de)(de)影(ying)(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)效率有直接的(de)(de)影(ying)(ying)響(xiang)。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難(nan)以保持在(zai)集(ji)(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，致使其重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)阻(zu)過高，到達集(ji)(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)易放出，在(zai)塵(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)壓梯度會產生局(ju)部擊穿和(he)放電(dian)(dian)(dian)現象(xiang)。這(zhe)些情況(kuang)都會造成(cheng)(cheng)除塵(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)器的基本原理(li)(li)是利用電(dian)(dian)(dian)力捕集煙氣中的粉(fen)塵(chen)，主(zhu)要(yao)包括以下(xia)四個相互有關的物理(li)(li)過程: (1) 氣體(ti)的電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)的荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)極移(yi)動(dong)。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)的捕集。
