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)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法來收(shou)捕(bu)廢氣(qi)中的(de)粉塵(chen)，它的(de)凈化(hua)(hua)工(gong)作上(shang)要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀(dian)兩個系(xi)統來完(wan)成的(de)，當含(han)塵(chen)氣(qi)體(ti)進人(ren)(ren)(ren)(ren)氣(qi)刺叭時，含(han)塵(chen)氣(qi)體(ti)受(shou)到氣(qi)流(liu)分布(bu)板以及(ji)折流(liu)板的(de)調整(zheng)后，使氣(qi)流(liu)能較(jiao)(jiao)均勻地進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴(kuo)大的(de)作用下，氣(qi)流(liu)速度迅速降低，其中有些(xie)較(jiao)(jiao)重的(de)塵(chen)粒便失去速度而沉(chen)降下來。進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)含(han)塵(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)(tong)人(ren)(ren)(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)氣(qi)體(ti)中存在大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)粉塵(chen)結合起來，使塵(chen)粒帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)作用下趨向本設(she)備陽(yang)(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)備采用負(fu)高壓制(zhi))和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積(ji)在相應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)(tong)過(guo)設(she)備陰陽(yang)(yang)極(ji)(ji)振(zhen)打系(xi)統的(de)振(zhen)打，使沉(chen)積(ji)在陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)粉塵(chen)振(zhen)落，進人(ren)(ren)(ren)(ren)集灰斗 通(tong)(tong)過(guo)排(pai)灰裝(zhuang)置放(fang)出，回收(shou)有物(wu)料，被)凈化(hua)(hua)的(de)氣(qi)體(ti)排(pai)入大氣(qi)。

工作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作(zuo)原(yuan)理(li)是利(li)用高(gao)壓(ya)電(dian)(dian)場(chang)使(shi)煙氣(qi)發生(sheng)電(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作(zuo)用下與氣(qi)流(liu)分離。負極(ji)由不(bu)同斷面形(xing)(xing)狀的(de)金屬導線制(zhi)成(cheng)(cheng)(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形(xing)(xing)狀的(de)金屬板制(zhi)成(cheng)(cheng)(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)(chen)性(xing)質、設備構造和煙氣(qi)流(liu)速等三個因素的(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻是評價(jia)導電(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率有直(zhi)接的(de)影(ying)響。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致(zhi)使(shi)其重返(fan)氣(qi)流(liu)。比(bi)電(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易(yi)放出，在(zai)塵(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)(cheng)(cheng)電(dian)(dian)壓(ya)梯度(du)會產生(sheng)局部擊穿和放電(dian)(dian)現象。這(zhe)些(xie)情況都會造成(cheng)(cheng)(cheng)除塵(chen)(chen)(chen)效(xiao)率下降。

電除塵(chen)器的(de)(de)基本原(yuan)理是利用電力捕(bu)集煙氣中的(de)(de)粉塵(chen)，主要(yao)包括以下四個(ge)相互有(you)關的(de)(de)物理過程: (1) 氣體(ti)的(de)(de)電離。(2) 粉塵(chen)的(de)(de)荷電。(3) 荷電粉塵(chen)向電極(ji)移動。(4) 荷電粉塵(chen)的(de)(de)捕(bu)集。
