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)除塵(chen)(chen)(chen)器是(shi)(shi)以靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕(bu)廢氣(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工作(zuo)上(shang)(shang)要是(shi)(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉(chen)淀兩個(ge)系統來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)進(jin)(jin)(jin)人氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流分布板以及折流板的(de)(de)(de)(de)調(diao)整(zheng)后(hou)，使(shi)氣(qi)流能較均(jun)勻地進(jin)(jin)(jin)人電(dian)(dian)(dian)場。在橫斷面(mian)擴大(da)的(de)(de)(de)(de)作(zuo)用下，氣(qi)流速度(du)迅速降(jiang)低(di)，其中有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失(shi)去速度(du)而沉(chen)降(jiang)下來(lai)。進(jin)(jin)(jin)人電(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高(gao)壓(ya)直流電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈(yun)現(xian)象(xiang)，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)(de)氣(qi)體(ti)中存在大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)與進(jin)(jin)(jin)人電(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下趨向本(ben)設備(bei)陽(yang)(yang)極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本(ben)設備(bei)采用負高(gao)壓(ya)制)和陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)分別沉(chen)積在相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)，通過設備(bei)陰(yin)陽(yang)(yang)極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)振打(da)，使(shi)沉(chen)積在陰(yin)陽(yang)(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)振落(luo)，進(jin)(jin)(jin)人集灰斗 通過排灰裝置放出(chu)，回收有物料，被)凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

靜電(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)工作(zuo)(zuo)原理(li)是利(li)用高(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)場(chang)(chang)使(shi)煙(yan)氣發生電(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)(chang)作(zuo)(zuo)用下(xia)與氣流(liu)分(fen)離(li)。負極(ji)(ji)由(you)不(bu)同(tong)斷面形(xing)狀的(de)(de)金屬導線制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)不(bu)同(tong)幾何形(xing)狀的(de)(de)金屬板(ban)制成(cheng)(cheng)，叫集塵(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)性能受(shou)粉(fen)塵(chen)性質、設(she)備構造和(he)煙(yan)氣流(liu)速等三個因素的(de)(de)影(ying)響。粉(fen)塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)(de)指(zhi)標，它(ta)對除塵(chen)效率(lv)有直接的(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)粒難(nan)以保持在(zai)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)阻過高(gao)(gao)，到(dao)達集塵(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)荷(he)不(bu)易放(fang)出，在(zai)塵(chen)層之(zhi)間(jian)形(xing)成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)(ya)梯度會產生局部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)現象。這些情況都會造成(cheng)(cheng)除塵(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵(chen)(chen)器(qi)的(de)基本原理是利用電(dian)(dian)力捕集煙氣中(zhong)的(de)粉(fen)(fen)塵(chen)(chen)，主要包括以下四個相互(hu)有關的(de)物(wu)理過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕集。
