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)(dian)(dian)除塵(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕(bu)廢氣(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化工作上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀兩個系(xi)統(tong)來完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)(liu)分(fen)布板(ban)以(yi)及折(zhe)流(liu)(liu)板(ban)的(de)(de)(de)(de)調整后(hou)(hou)，使(shi)氣(qi)流(liu)(liu)能較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面(mian)擴大的(de)(de)(de)(de)作用下，氣(qi)流(liu)(liu)速(su)度迅速(su)降(jiang)低，其中有些較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速(su)度而沉降(jiang)下來。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)(hou)的(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)中存在(zai)(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合(he)起來，使(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下趨向(xiang)本(ben)設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備(bei)采(cai)用負(fu)高壓制)和(he)陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉積(ji)在(zai)(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通過設備(bei)陰(yin)陽(yang)極(ji)(ji)振打系(xi)統(tong)的(de)(de)(de)(de)振打，使(shi)沉積(ji)在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進(jin)(jin)人(ren)集灰斗 通過排灰裝(zhuang)置放出，回收(shou)有物料(liao)，被)凈化的(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)排入大氣(qi)。

工作(zuo)原理

靜電(dian)除塵(chen)器(qi)的(de)(de)工作原理是利用高(gao)壓電(dian)場(chang)使煙氣(qi)(qi)發生(sheng)電(dian)離(li)，氣(qi)(qi)流中的(de)(de)粉(fen)塵(chen)荷電(dian)在電(dian)場(chang)作用下(xia)與氣(qi)(qi)流分離(li)。負極(ji)由(you)不(bu)同斷面形狀的(de)(de)金屬導線(xian)制成，叫放電(dian)電(dian)極(ji)。正(zheng)極(ji)由(you)不(bu)同幾何形狀的(de)(de)金屬板制成，叫集塵(chen)電(dian)極(ji)。靜電(dian)除塵(chen)器(qi)的(de)(de)性能受(shou)粉(fen)塵(chen)性質、設備(bei)構造和(he)煙氣(qi)(qi)流速等三個(ge)因素(su)的(de)(de)影(ying)響。粉(fen)塵(chen)的(de)(de)比電(dian)阻是評價導電(dian)性的(de)(de)指標，它對(dui)除塵(chen)效率(lv)有直接的(de)(de)影(ying)響。比電(dian)阻過低(di)，塵(chen)粒(li)難(nan)以保持在集塵(chen)電(dian)極(ji)上(shang)，致使其重返氣(qi)(qi)流。比電(dian)阻過高(gao)，到達集塵(chen)電(dian)極(ji)的(de)(de)塵(chen)粒(li)電(dian)荷不(bu)易放出，在塵(chen)層之間形成電(dian)壓梯度會(hui)產生(sheng)局部擊穿和(he)放電(dian)現象。這(zhe)些情(qing)況都會(hui)造成除塵(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵(chen)(chen)器的(de)基本原理(li)是利用電(dian)(dian)力捕集煙氣中的(de)粉(fen)塵(chen)(chen)，主要包括以下四個相(xiang)互(hu)有關的(de)物理(li)過(guo)程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集。
