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(shi)靜電(dian)(dian)除塵(chen)(chen)器是(shi)(shi)以(yi)靜電(dian)(dian)凈(jing)化(hua)法來(lai)(lai)收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵(chen)(chen)，它的(de)凈(jing)化(hua)工作(zuo)上要是(shi)(shi)依靠電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)(ji)和沉淀兩個系(xi)統來(lai)(lai)完成的(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進人(ren)(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時(shi)，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)分布板以(yi)及折流(liu)(liu)(liu)板的(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)能較(jiao)均(jun)勻地進人(ren)(ren)(ren)(ren)電(dian)(dian)場。在橫斷面(mian)擴大的(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度迅速(su)降(jiang)低，其中(zhong)有(you)些較(jiao)重的(de)塵(chen)(chen)粒便失去速(su)度而沉降(jiang)下來(lai)(lai)。進人(ren)(ren)(ren)(ren)電(dian)(dian)場的(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由(you)于電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)(ji)通人(ren)(ren)(ren)(ren)高壓(ya)直流(liu)(liu)(liu)電(dian)(dian)，則在電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)(ji)附近產生電(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在大量(liang)的(de)電(dian)(dian)子和離子，這(zhe)些電(dian)(dian)子和離子與進人(ren)(ren)(ren)(ren)電(dian)(dian)場的(de)粉(fen)塵(chen)(chen)結合(he)起(qi)來(lai)(lai)，使(shi)塵(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)場力的(de)作(zuo)用下趨向本設備陽極(ji)(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)(ji)、本設備采(cai)用負高壓(ya)制)和陰(yin)(yin)極(ji)(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)子分別沉積(ji)在相應的(de)電(dian)(dian)極(ji)(ji)(ji)(ji)(ji)(ji)上，通過(guo)設備陰(yin)(yin)陽極(ji)(ji)(ji)(ji)(ji)(ji)振打(da)系(xi)統的(de)振打(da)，使(shi)沉積(ji)在陰(yin)(yin)陽電(dian)(dian)極(ji)(ji)(ji)(ji)(ji)(ji)上的(de)粉(fen)塵(chen)(chen)振落，進人(ren)(ren)(ren)(ren)集灰(hui)斗 通過(guo)排灰(hui)裝(zhuang)置放出，回收有(you)物料，被)凈(jing)化(hua)的(de)氣(qi)(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流分離。負極(ji)(ji)由不(bu)同斷(duan)面形狀的(de)(de)(de)(de)(de)金屬導線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何形狀的(de)(de)(de)(de)(de)金屬板制(zhi)成(cheng)(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造和(he)煙(yan)氣(qi)流速(su)等三個因素的(de)(de)(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓梯度會產(chan)生(sheng)局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些情況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效率下(xia)降(jiang)。

電(dian)除塵(chen)器的(de)基(ji)本原理是利(li)用電(dian)力捕集煙(yan)氣(qi)中的(de)粉(fen)塵(chen)，主要包括以下四個(ge)相(xiang)互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)的(de)捕集。
