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)器是以(yi)(yi)靜電(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工(gong)作上(shang)要是依靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和(he)沉淀兩個系(xi)(xi)統(tong)來(lai)完(wan)成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體進人(ren)(ren)氣(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流分(fen)布板(ban)以(yi)(yi)及折流板(ban)的(de)(de)調整后(hou)(hou)，使(shi)(shi)氣(qi)(qi)流能較均勻地進人(ren)(ren)電(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)(de)作用(yong)下，氣(qi)(qi)流速度迅速降低，其(qi)中有(you)些較重(zhong)的(de)(de)塵(chen)(chen)粒便(bian)失去速度而沉降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高(gao)壓直流電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)(hou)的(de)(de)氣(qi)(qi)體中存在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離子(zi)與進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)場力(li)的(de)(de)作用(yong)下趨(qu)向本設備陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備采用(yong)負高(gao)壓制(zhi))和(he)陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)，通(tong)過設備陰陽(yang)極(ji)(ji)(ji)(ji)振(zhen)(zhen)打系(xi)(xi)統(tong)的(de)(de)振(zhen)(zhen)打，使(shi)(shi)沉積在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)的(de)(de)粉塵(chen)(chen)振(zhen)(zhen)落，進人(ren)(ren)集灰斗 通(tong)過排(pai)灰裝置放出，回收有(you)物(wu)料(liao)，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體排(pai)入(ru)大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作(zuo)原(yuan)理(li)是利(li)用高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與(yu)氣(qi)流分離(li)。負極(ji)(ji)由不(bu)同(tong)斷面形(xing)狀(zhuang)的(de)(de)金屬(shu)導線制成(cheng)(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同(tong)幾何形(xing)狀(zhuang)的(de)(de)金屬(shu)板制成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)性質(zhi)、設備構造和煙(yan)氣(qi)流速等(deng)三(san)個因素的(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)效(xiao)率(lv)有直接的(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難(nan)以(yi)保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重(zhong)返氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)層之間(jian)形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會造成(cheng)(cheng)除(chu)塵(chen)(chen)效(xiao)率(lv)下降(jiang)。

電(dian)(dian)除塵(chen)器的(de)(de)基本原理是利用電(dian)(dian)力捕(bu)集煙氣中的(de)(de)粉(fen)塵(chen)，主要包括以下四個(ge)相互有關的(de)(de)物理過程: (1) 氣體(ti)的(de)(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)的(de)(de)捕(bu)集。
