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)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它(ta)的(de)(de)凈(jing)化工(gong)作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極和(he)沉淀兩個系(xi)統(tong)來(lai)完成的(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)(de)調整后(hou)(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴大的(de)(de)作用(yong)下，氣(qi)(qi)(qi)流(liu)速度(du)迅速降低，其中有些(xie)(xie)較重的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)便失去速度(du)而沉降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈極通(tong)人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈極附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中存在大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)作用(yong)下趨向本設(she)備(bei)(bei)陽(yang)極(正極、本設(she)備(bei)(bei)采(cai)用(yong)負高壓制)和(he)陰極(負極) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積(ji)(ji)在相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)，通(tong)過(guo)設(she)備(bei)(bei)陰陽(yang)極振(zhen)打系(xi)統(tong)的(de)(de)振(zhen)打，使(shi)沉積(ji)(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放出(chu)，回收(shou)有物料，被(bei))凈(jing)化的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排(pai)入(ru)大氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的工作(zuo)原理(li)是利用高壓電(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與(yu)氣(qi)(qi)流分(fen)離(li)。負極由(you)不同(tong)斷面形狀(zhuang)的金屬導線(xian)制成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)不同(tong)幾何形狀(zhuang)的金屬板制成，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構(gou)造和(he)煙(yan)氣(qi)(qi)流速等三個因素的影(ying)響。粉(fen)塵(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性(xing)的指(zhi)標，它(ta)對除塵(chen)(chen)(chen)效率有直接(jie)的影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒難以保持(chi)在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)壓梯(ti)度(du)會產生局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況(kuang)都(dou)會造成除塵(chen)(chen)(chen)效率下(xia)降。

電除塵(chen)器(qi)的(de)(de)基本原(yuan)理是利用電力捕(bu)集煙氣中的(de)(de)粉(fen)塵(chen)，主要包括以下四個相互有關的(de)(de)物理過程: (1) 氣體(ti)(ti)的(de)(de)電離。(2) 粉(fen)塵(chen)的(de)(de)荷電。(3) 荷電粉(fen)塵(chen)向電極移動(dong)。(4) 荷電粉(fen)塵(chen)的(de)(de)捕(bu)集。
