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)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈化工(gong)作(zuo)上要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀兩個(ge)系統(tong)來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)流分布板以及折流板的(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流能較(jiao)均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷面(mian)擴(kuo)大的(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)(qi)(qi)流速度(du)迅(xun)速降低，其中有(you)些較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速度(du)而沉降下(xia)來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中存在大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下(xia)趨向本設備陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設備采用負(fu)高壓(ya)制)和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設備陰陽極(ji)(ji)振打系統(tong)的(de)(de)(de)(de)振打，使(shi)沉積在陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)振落，進(jin)(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝置放出，回收有(you)物料(liao)，被(bei))凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)工作原理是利(li)用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)(liu)中的(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣流(liu)(liu)分離(li)。負極(ji)(ji)由不(bu)同斷(duan)面(mian)形狀的(de)金(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何形狀的(de)金(jin)屬板制成(cheng)，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設(she)備構造和煙氣流(liu)(liu)速等(deng)三個因素(su)的(de)影(ying)響。粉(fen)塵(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)效(xiao)率有(you)直接的(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)粒(li)難以保(bao)持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產(chan)生(sheng)局(ju)部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)現(xian)象(xiang)。這些(xie)情況都會造成(cheng)除塵(chen)效(xiao)率下降。

電(dian)除塵器(qi)的(de)(de)基本原(yuan)理是利用電(dian)力捕集煙氣(qi)中(zhong)的(de)(de)粉(fen)塵，主要包括以下四個相(xiang)互有關的(de)(de)物理過程: (1) 氣(qi)體的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵的(de)(de)捕集。
