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(yi)靜電(dian)(dian)(dian)凈化(hua)(hua)法來收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈化(hua)(hua)工作上(shang)要是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀兩個系(xi)統來完(wan)成的(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)(de)(de)調整后，使氣(qi)(qi)流(liu)能較(jiao)均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)。在橫(heng)斷面(mian)擴大(da)(da)的(de)(de)(de)作用下，氣(qi)(qi)流(liu)速(su)(su)度(du)迅速(su)(su)降(jiang)低，其中有些較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失(shi)去(qu)速(su)(su)度(du)而沉(chen)降(jiang)下來。進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中存在大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合(he)起來，使塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下趨向本設備(bei)陽極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用負高壓(ya)制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)分別沉(chen)積(ji)在相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)設備(bei)陰陽極(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)振(zhen)打，使沉(chen)積(ji)在陰陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放(fang)出，回收(shou)有物(wu)料，被)凈化(hua)(hua)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排(pai)入大(da)(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的工作原理是(shi)利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下(xia)與氣(qi)流(liu)分離。負(fu)極(ji)(ji)由不同(tong)斷面形狀(zhuang)的金(jin)屬導線制成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾(ji)何形狀(zhuang)的金(jin)屬板(ban)制成(cheng)(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和(he)(he)煙(yan)氣(qi)流(liu)速(su)等三個因素的影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的指標(biao)，它(ta)對除塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直接的影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒難(nan)以保持(chi)在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重(zhong)返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在塵(chen)(chen)(chen)(chen)(chen)層之間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生局(ju)部擊穿和(he)(he)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下(xia)降。

電(dian)除(chu)塵(chen)(chen)器的(de)基本原理是利(li)用電(dian)力捕集煙氣中的(de)粉塵(chen)(chen)，主要包括(kuo)以下四個(ge)相(xiang)互有關的(de)物理過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)(chen)向電(dian)極(ji)移動。(4) 荷(he)電(dian)粉塵(chen)(chen)的(de)捕集。
