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)除塵(chen)(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)法來收捕(bu)廢氣(qi)中的(de)粉(fen)塵(chen)(chen)(chen)，它(ta)的(de)凈(jing)化(hua)工作(zuo)上(shang)要(yao)是(shi)依靠(kao)電(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)沉淀兩(liang)個系統來完成的(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)進人(ren)(ren)(ren)氣(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)受到氣(qi)流分布(bu)板(ban)以(yi)及(ji)折流板(ban)的(de)調整后，使(shi)氣(qi)流能較均勻地(di)進人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)作(zuo)用下(xia)(xia)，氣(qi)流速度迅速降低(di)，其中有(you)些較重的(de)塵(chen)(chen)(chen)粒(li)(li)便失(shi)去速度而沉降下(xia)(xia)來。進人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)暈(yun)(yun)極(ji)通人(ren)(ren)(ren)高(gao)壓(ya)直流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)氣(qi)體(ti)(ti)(ti)(ti)中存在(zai)大量的(de)電(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)子和(he)離(li)子與進人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)粉(fen)塵(chen)(chen)(chen)結(jie)合(he)起(qi)來，使(shi)塵(chen)(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)(li)在(zai)電(dian)(dian)(dian)場(chang)力的(de)作(zuo)用下(xia)(xia)趨(qu)向(xiang)本設備陽極(ji)(正極(ji)、本設備采用負(fu)高(gao)壓(ya)制)和(he)陰極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分別(bie)沉積在(zai)相應的(de)電(dian)(dian)(dian)極(ji)上(shang)，通過設備陰陽極(ji)振打(da)系統的(de)振打(da)，使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)極(ji)上(shang)的(de)粉(fen)塵(chen)(chen)(chen)振落，進人(ren)(ren)(ren)集(ji)灰(hui)(hui)斗 通過排灰(hui)(hui)裝置(zhi)放(fang)出，回收有(you)物料，被)凈(jing)化(hua)的(de)氣(qi)體(ti)(ti)(ti)(ti)排入大氣(qi)。

工作(zuo)原(yuan)理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)工作原理是(shi)利用高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流分離(li)。負極(ji)由(you)不(bu)同斷面(mian)形(xing)狀的(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不(bu)同幾何(he)形(xing)狀的(de)金屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)性(xing)(xing)能(neng)受粉塵(chen)(chen)性(xing)(xing)質、設備構造(zao)和(he)煙氣(qi)(qi)流速等(deng)三(san)個因素的(de)影響(xiang)(xiang)。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)指標(biao)，它(ta)對除(chu)塵(chen)(chen)效率有(you)直接的(de)影響(xiang)(xiang)。比電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成(cheng)除(chu)塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)(chen)(chen)器的(de)基(ji)本原理是利用(yong)電(dian)(dian)力捕(bu)集煙氣(qi)中的(de)粉(fen)塵(chen)(chen)(chen)，主要包括以下四個(ge)相互有關的(de)物(wu)理過程: (1) 氣(qi)體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)(chen)(chen)向電(dian)(dian)極移(yi)動(dong)。(4) 荷電(dian)(dian)粉(fen)塵(chen)(chen)(chen)的(de)捕(bu)集。
