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(wo)式靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈化(hua)法來(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈化(hua)工作上要是依(yi)靠(kao)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)和沉(chen)淀(dian)兩(liang)個系統來(lai)(lai)完成的(de)(de)(de)(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)受(shou)到氣(qi)(qi)(qi)流(liu)(liu)分布板以(yi)及折(zhe)流(liu)(liu)板的(de)(de)(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)流(liu)(liu)能較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴(kuo)大(da)的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速(su)度(du)迅速(su)降(jiang)低，其(qi)中有些(xie)較(jiao)重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉(chen)降(jiang)下(xia)來(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈(yun)(yun)現象(xiang)，使(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些(xie)電(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合(he)起(qi)來(lai)(lai)，使(shi)(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)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)趨(qu)向本設(she)備陽(yang)(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備采用(yong)負高壓(ya)制)和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)(zi)分別(bie)沉(chen)積(ji)在(zai)(zai)相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過設(she)備陰陽(yang)(yang)極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)(de)(de)振打(da)，使(shi)(shi)沉(chen)積(ji)在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落，進(jin)人(ren)(ren)集(ji)灰(hui)斗 通(tong)過排灰(hui)裝置(zhi)放(fang)出，回收有物料(liao)，被)凈化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作原(yuan)理是利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)場使(shi)煙(yan)氣發生電(dian)(dian)(dian)離，氣流(liu)(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用(yong)下與(yu)氣流(liu)(liu)分離。負極(ji)由(you)(you)不同(tong)斷面形(xing)狀的(de)金屬(shu)導線(xian)制(zhi)成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)(you)不同(tong)幾何(he)形(xing)狀的(de)金屬(shu)板制(zhi)成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備構造和(he)煙(yan)氣流(liu)(liu)速等三個因(yin)素的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性(xing)(xing)的(de)指(zhi)標(biao)，它對除塵(chen)(chen)(chen)效率有直接的(de)影響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以(yi)保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其(qi)重返氣流(liu)(liu)。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產(chan)生局部擊穿和(he)放電(dian)(dian)(dian)現象。這些(xie)情況都會(hui)(hui)造成除塵(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵器(qi)的(de)(de)基本原(yuan)理(li)是利用電(dian)(dian)力捕(bu)集(ji)(ji)煙氣(qi)中的(de)(de)粉(fen)塵，主要(yao)包括以下四個相互有(you)關的(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)電(dian)(dian)離。(2) 粉(fen)塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵向(xiang)電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉(fen)塵的(de)(de)捕(bu)集(ji)(ji)。
