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)(dian)(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈化工作(zuo)(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)(he)沉淀(dian)兩個系統(tong)來完成的(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)進人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)(de)(de)(de)(de)調(diao)整后，使氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴(kuo)大的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降低，其中有些較(jiao)重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速度而沉降下來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)中存在大量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(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)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用下趨向本設(she)備(bei)陽極(ji)(正極(ji)、本設(she)備(bei)采用負高壓(ya)制)和(he)(he)陰極(ji)(負極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積在相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設(she)備(bei)陰陽極(ji)振打系統(tong)的(de)(de)(de)(de)(de)(de)振打，使沉積在陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落(luo)，進人(ren)集(ji)灰斗 通過排(pai)灰裝置放出，回收(shou)有物料，被)凈化的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)排(pai)入大氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作原理是(shi)利用(yong)高(gao)壓(ya)電(dian)(dian)場(chang)使煙氣發生電(dian)(dian)離，氣流(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)(zai)電(dian)(dian)場(chang)作用(yong)下(xia)與氣流(liu)分離。負極(ji)由(you)不(bu)同(tong)斷面形狀的(de)(de)金屬導線制成(cheng)，叫放(fang)(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同(tong)幾(ji)何(he)形狀的(de)(de)金屬板(ban)制成(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣流(liu)速等(deng)三個因素的(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)性(xing)的(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)(chen)(chen)效率有直接(jie)的(de)(de)影響。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣流(liu)。比(bi)電(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放(fang)(fang)出，在(zai)(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓(ya)梯度會(hui)產生局部(bu)擊穿和(he)放(fang)(fang)電(dian)(dian)現象(xiang)。這些情(qing)況都會(hui)造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)除塵器的(de)基本原理(li)是(shi)利用電(dian)力捕集煙氣中的(de)粉(fen)塵，主要包括以(yi)下(xia)四個相互有關的(de)物理(li)過程(cheng): (1) 氣體的(de)電(dian)離(li)。(2) 粉(fen)塵的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵向電(dian)極移動(dong)。(4) 荷(he)電(dian)粉(fen)塵的(de)捕集。
