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(wo)式靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)中的(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)凈(jing)化工作(zuo)上要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)淀(dian)兩個系統(tong)來(lai)完成(cheng)的(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)體(ti)進(jin)人(ren)氣(qi)刺叭(ba)時，含(han)塵(chen)氣(qi)體(ti)受到氣(qi)流(liu)分布板以及折(zhe)流(liu)板的(de)(de)(de)(de)調整(zheng)后(hou)，使(shi)(shi)氣(qi)流(liu)能較均(jun)勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)流(liu)速度迅速降(jiang)(jiang)低，其(qi)中有(you)些較重的(de)(de)(de)(de)塵(chen)粒便失去速度而(er)沉(chen)降(jiang)(jiang)下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)體(ti)中存(cun)在(zai)(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)結合(he)起來(lai)，使(shi)(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用(yong)下趨向本設(she)備(bei)(bei)陽極(ji)(正(zheng)極(ji)、本設(she)備(bei)(bei)采用(yong)負(fu)高壓制)和陰極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設(she)備(bei)(bei)陰陽極(ji)振(zhen)打系統(tong)的(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉塵(chen)振(zhen)落，進(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝(zhuang)置放(fang)出，回收有(you)物料(liao)，被)凈(jing)化的(de)(de)(de)(de)氣(qi)體(ti)排入大氣(qi)。

工(gong)作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下(xia)與氣(qi)流(liu)分離。負極(ji)由不同(tong)斷面形(xing)狀(zhuang)的(de)金(jin)屬導線制成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形(xing)狀(zhuang)的(de)金(jin)屬板制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)性能受(shou)粉(fen)塵(chen)(chen)性質、設備構造和煙氣(qi)流(liu)速等三個因素(su)的(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)(dian)性的(de)指標(biao)，它對除塵(chen)(chen)效(xiao)率有直接(jie)的(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難(nan)以保持(chi)在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達(da)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出，在(zai)塵(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造成除塵(chen)(chen)效(xiao)率下(xia)降。

電除塵(chen)(chen)器的(de)基本原理(li)(li)是(shi)利用電力捕集煙氣中的(de)粉塵(chen)(chen)，主要(yao)包(bao)括以下四(si)個相(xiang)互有關的(de)物理(li)(li)過程: (1) 氣體(ti)的(de)電離。(2) 粉塵(chen)(chen)的(de)荷電。(3) 荷電粉塵(chen)(chen)向電極移(yi)動(dong)。(4) 荷電粉塵(chen)(chen)的(de)捕集。
