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(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收捕(bu)廢氣(qi)(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉淀兩個(ge)系統來(lai)(lai)完成的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人氣(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流分布板(ban)以(yi)及折流板(ban)的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)(qi)流能較均勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴大的(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)(qi)流速度迅(xun)速降低(di)，其中有(you)些較重的(de)(de)塵(chen)(chen)粒便失去(qu)速度而沉降下(xia)來(lai)(lai)。進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中存在(zai)(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)粒帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下(xia)趨向本設備陽(yang)極(ji)(正極(ji)、本設備采用負高壓(ya)制)和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積在(zai)(zai)相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設備陰陽(yang)極(ji)振打系統的(de)(de)振打，使沉積在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)粉塵(chen)(chen)振落，進(jin)(jin)人集灰(hui)斗 通(tong)過(guo)排灰(hui)裝(zhuang)置放出，回收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)工作(zuo)原理是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)粉塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與氣流(liu)分離。負極(ji)(ji)由不同(tong)斷面形(xing)狀(zhuang)的(de)(de)金屬(shu)導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形(xing)狀(zhuang)的(de)(de)金屬(shu)板制(zhi)成，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)性(xing)能受粉塵(chen)性(xing)質、設備構造和煙(yan)氣流(liu)速(su)等三個因(yin)素的(de)(de)影響。粉塵(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)效(xiao)(xiao)率有直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒難以保持(chi)在(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在(zai)塵(chen)層之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)產生(sheng)局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)造成除塵(chen)效(xiao)(xiao)率下(xia)降。

電除(chu)塵(chen)器的(de)基(ji)本(ben)原理(li)(li)是利用電力捕(bu)集煙(yan)氣中的(de)粉(fen)塵(chen)，主要包括以下四個相(xiang)互(hu)有關的(de)物理(li)(li)過(guo)程: (1) 氣體的(de)電離。(2) 粉(fen)塵(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)向電極移動。(4) 荷(he)電粉(fen)塵(chen)的(de)捕(bu)集。
