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(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)(jing)化工作(zuo)上(shang)(shang)要是(shi)依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)淀兩(liang)個系(xi)統(tong)來(lai)完成的(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受(shou)到(dao)氣(qi)(qi)(qi)流分布板以及折流板的(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)流能較均(jun)勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴(kuo)大(da)(da)的(de)(de)作(zuo)用(yong)(yong)下(xia)，氣(qi)(qi)(qi)流速(su)(su)(su)度迅速(su)(su)(su)降低，其中有(you)些(xie)較重的(de)(de)塵(chen)(chen)粒便失(shi)去速(su)(su)(su)度而沉(chen)降下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高(gao)(gao)壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中存在(zai)(zai)大(da)(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(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)結合起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)(yong)下(xia)趨向本(ben)設(she)備陽極(ji)(正(zheng)極(ji)、本(ben)設(she)備采用(yong)(yong)負高(gao)(gao)壓制)和陰(yin)極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通過(guo)設(she)備陰(yin)陽極(ji)振(zhen)打系(xi)統(tong)的(de)(de)振(zhen)打，使沉(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)人(ren)集(ji)灰斗 通過(guo)排灰裝(zhuang)置放出(chu)，回收有(you)物料，被)凈(jing)(jing)化的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排入大(da)(da)氣(qi)(qi)(qi)。

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)(de)工作(zuo)原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流(liu)(liu)分離。負極(ji)由不同斷面形(xing)狀的(de)(de)(de)(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何(he)形(xing)狀的(de)(de)(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)性(xing)質、設備構(gou)造和煙氣(qi)流(liu)(liu)速等三個因素的(de)(de)(de)(de)影響。粉(fen)(fen)塵(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指(zhi)標(biao)，它對除(chu)塵(chen)(chen)效(xiao)(xiao)率(lv)(lv)有直接的(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難(nan)以保持在(zai)(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重返(fan)氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出，在(zai)(zai)(zai)塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯(ti)度(du)會(hui)產生局(ju)部(bu)擊穿和放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)除(chu)塵(chen)(chen)效(xiao)(xiao)率(lv)(lv)下降(jiang)。

電除塵器的(de)基本原理(li)是利用電力捕集(ji)煙氣中(zhong)的(de)粉(fen)塵，主要(yao)包括以下四個相互有關的(de)物理(li)過(guo)程: (1) 氣體的(de)電離。(2) 粉(fen)塵的(de)荷電。(3) 荷電粉(fen)塵向(xiang)電極移動。(4) 荷電粉(fen)塵的(de)捕集(ji)。
