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)器(qi)是以(yi)靜電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收捕廢氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈(jing)化工(gong)作(zuo)(zuo)上(shang)要是依靠(kao)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)沉淀兩個系統來(lai)(lai)完成的(de)(de)，當含塵(chen)氣(qi)(qi)體(ti)(ti)(ti)(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)刺叭(ba)時，含塵(chen)氣(qi)(qi)體(ti)(ti)(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)(liu)能(neng)較均(jun)勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)。在橫斷面(mian)擴大的(de)(de)作(zuo)(zuo)用下，氣(qi)(qi)流(liu)(liu)速(su)度迅速(su)降(jiang)低，其中有(you)些較重的(de)(de)塵(chen)粒便失去速(su)度而沉降(jiang)下來(lai)(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)含塵(chen)氣(qi)(qi)體(ti)(ti)(ti)(ti)由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)人(ren)(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)(ti)中存在大量的(de)(de)電(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)子和(he)離子與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)塵(chen)結合(he)起來(lai)(lai)，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作(zuo)(zuo)用下趨向(xiang)本設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用負高壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子分別沉積在相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設備(bei)陰(yin)陽(yang)極(ji)(ji)振(zhen)打系統的(de)(de)振(zhen)打，使(shi)沉積在陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)人(ren)(ren)(ren)集灰斗 通(tong)過排(pai)灰裝置放出(chu)，回收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)(ti)排(pai)入大氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)工作(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)場使煙氣(qi)發(fa)生電(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用下與氣(qi)流(liu)分離。負極(ji)(ji)(ji)由不同斷面形(xing)狀的(de)金屬導線(xian)制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同幾何形(xing)狀的(de)金屬板(ban)制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)性能受粉(fen)塵(chen)(chen)性質、設備構造(zao)和(he)(he)煙氣(qi)流(liu)速等三個因(yin)素的(de)影響。粉(fen)塵(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)效(xiao)率(lv)有直接的(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)上，致使其重返氣(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻過高，到達(da)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)的(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿和(he)(he)放電(dian)(dian)(dian)現象(xiang)。這些(xie)情況都會(hui)造(zao)成除塵(chen)(chen)效(xiao)率(lv)下降。

電(dian)除塵器(qi)的(de)基本(ben)原理(li)是利用(yong)電(dian)力捕集煙氣(qi)中的(de)粉(fen)(fen)塵，主要(yao)包括以(yi)下四個相互有關的(de)物(wu)理(li)過程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉(fen)(fen)塵的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)(fen)塵的(de)捕集。
