XWD型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)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)(de)(de)凈(jing)化工作上要是(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩個系統(tong)來(lai)(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)受到(dao)氣(qi)(qi)(qi)(qi)流分布板以及折流板的(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)流能較均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流速(su)度(du)迅(xun)速(su)降低(di)，其(qi)中(zhong)有些(xie)較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉降下來(lai)(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)通(tong)人(ren)高壓直(zhi)流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些(xie)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)作用下趨(qu)向本(ben)設備(bei)陽極(ji)(正(zheng)極(ji)、本(ben)設備(bei)采用負高壓制(zhi))和(he)陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分別沉積在(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通(tong)過設備(bei)陰陽極(ji)振打系統(tong)的(de)(de)(de)(de)振打，使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振落(luo)，進(jin)(jin)人(ren)集灰斗 通(tong)過排灰裝置放出，回(hui)收有物料(liao)，被(bei))凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵器(qi)的(de)(de)工(gong)作(zuo)原理(li)是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)(liu)中的(de)(de)粉塵荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流(liu)(liu)分離(li)。負極(ji)(ji)(ji)(ji)由不(bu)同斷面形(xing)(xing)狀的(de)(de)金屬導線制成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由不(bu)同幾(ji)何(he)形(xing)(xing)狀的(de)(de)金屬板制成，叫(jiao)集(ji)(ji)塵電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵器(qi)的(de)(de)性(xing)能(neng)受粉塵性(xing)質、設備構造(zao)和煙氣(qi)流(liu)(liu)速等三個因素的(de)(de)影響。粉塵的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵效率有直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵粒難以保(bao)持在(zai)集(ji)(ji)塵電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)，致使其重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到達集(ji)(ji)塵電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)的(de)(de)塵粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)塵層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)成除(chu)塵效率下降。

電(dian)除(chu)塵(chen)(chen)器(qi)的(de)基本原理是利(li)用(yong)電(dian)力捕(bu)集煙氣(qi)中的(de)粉(fen)(fen)塵(chen)(chen)，主要包括以下四個相(xiang)互(hu)有(you)關的(de)物理過程(cheng): (1) 氣(qi)體(ti)的(de)電(dian)離(li)。(2) 粉(fen)(fen)塵(chen)(chen)的(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕(bu)集。
