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)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收(shou)捕廢氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工(gong)作上要(yao)是依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩個系(xi)統來(lai)完成的(de)(de)，當含塵(chen)(chen)氣(qi)體進人氣(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)體受到(dao)氣(qi)流分布(bu)板以(yi)及折流板的(de)(de)調整后，使(shi)(shi)氣(qi)流能較均勻(yun)地進人電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)(zai)(zai)橫斷面擴大的(de)(de)作用(yong)下，氣(qi)流速度(du)(du)迅(xun)速降低，其中有些(xie)較重的(de)(de)塵(chen)(chen)粒便(bian)失(shi)去速度(du)(du)而沉(chen)降下來(lai)。進人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)(shi)氣(qi)體電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)體中存在(zai)(zai)(zai)(zai)(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)子和離子與進人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下趨向本(ben)設備陽(yang)極(ji)(正極(ji)、本(ben)設備采用(yong)負(fu)高壓制)和陰極(ji)(負(fu)極(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)(zai)(zai)(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設備陰陽(yang)極(ji)振(zhen)(zhen)打系(xi)統的(de)(de)振(zhen)(zhen)打，使(shi)(shi)沉(chen)積(ji)在(zai)(zai)(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)粉(fen)塵(chen)(chen)振(zhen)(zhen)落，進人集灰斗 通(tong)過(guo)排灰裝置放出(chu)，回收(shou)有物料，被)凈(jing)化(hua)的(de)(de)氣(qi)體排入大氣(qi)。

工(gong)作原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵器(qi)的(de)工作(zuo)原(yuan)理(li)是利用(yong)(yong)高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)粉(fen)塵荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作(zuo)用(yong)(yong)下(xia)與氣(qi)流(liu)分離。負極(ji)由不同(tong)(tong)斷面形狀的(de)金(jin)屬(shu)導(dao)線(xian)制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)(tong)幾(ji)何形狀的(de)金(jin)屬(shu)板制成，叫集塵電(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵器(qi)的(de)性(xing)能受粉(fen)塵性(xing)質、設備構(gou)造(zao)和(he)煙(yan)氣(qi)流(liu)速等(deng)三個因素(su)的(de)影(ying)響(xiang)(xiang)。粉(fen)塵的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)塵效(xiao)率有(you)直接的(de)影(ying)響(xiang)(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵粒(li)難以保(bao)持(chi)在(zai)集塵電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集塵電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵粒(li)電(dian)(dian)(dian)(dian)(dian)荷不易放出，在(zai)塵層之間(jian)形成電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生(sheng)局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些情況都會造(zao)成除(chu)塵效(xiao)率下(xia)降。

電(dian)(dian)除(chu)塵器的基本原理是利用電(dian)(dian)力捕集煙氣中的粉塵，主(zhu)要包括以下(xia)四個(ge)相互(hu)有(you)關(guan)的物理過程: (1) 氣體(ti)的電(dian)(dian)離。(2) 粉塵的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵的捕集。
