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)除塵(chen)器是以靜(jing)電(dian)(dian)凈(jing)化(hua)法來收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)，它的(de)(de)凈(jing)化(hua)工作(zuo)上要是依(yi)靠(kao)電(dian)(dian)暈(yun)極(ji)(ji)和(he)(he)沉(chen)淀兩(liang)個(ge)系(xi)統來完(wan)成(cheng)的(de)(de)，當(dang)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)進(jin)人氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分布板(ban)(ban)以及折(zhe)流(liu)板(ban)(ban)的(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能較均勻地(di)進(jin)人電(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大(da)的(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流(liu)速度迅速降低，其中(zhong)有些較重的(de)(de)塵(chen)粒(li)便(bian)失去速度而沉(chen)降下來。進(jin)人電(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)人高壓(ya)直(zhi)流(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)極(ji)(ji)附近產生(sheng)電(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存在(zai)大(da)量(liang)的(de)(de)電(dian)(dian)子(zi)和(he)(he)離子(zi)，這些電(dian)(dian)子(zi)和(he)(he)離子(zi)與進(jin)人電(dian)(dian)場(chang)的(de)(de)粉塵(chen)結合起來，使(shi)塵(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)場(chang)力的(de)(de)作(zuo)用下趨(qu)向本(ben)設(she)備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采用負高壓(ya)制)和(he)(he)陰(yin)(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)子(zi)分別沉(chen)積在(zai)相應的(de)(de)電(dian)(dian)極(ji)(ji)上，通(tong)(tong)過(guo)(guo)設(she)備陰(yin)(yin)陽極(ji)(ji)振打系(xi)統的(de)(de)振打，使(shi)沉(chen)積在(zai)陰(yin)(yin)陽電(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)振落，進(jin)人集灰(hui)斗 通(tong)(tong)過(guo)(guo)排灰(hui)裝(zhuang)置放出(chu)，回收有物料，被(bei))凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作原理(li)是利用高壓電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下與氣(qi)流分離。負極(ji)由不同斷面形狀的(de)(de)金屬(shu)導線制成(cheng)，叫(jiao)(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何(he)形狀的(de)(de)金屬(shu)板制成(cheng)，叫(jiao)(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設(she)備(bei)構造(zao)和煙氣(qi)流速(su)等(deng)三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)性(xing)(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)效率有直接(jie)的(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣(qi)流。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放出(chu)，在(zai)塵(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)現(xian)象。這(zhe)些情(qing)況(kuang)都(dou)會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)效率下降。

電除塵器(qi)的(de)(de)基本原理是利用電力(li)捕集(ji)煙(yan)氣(qi)中的(de)(de)粉(fen)(fen)塵，主要包括以下四個相互有關(guan)的(de)(de)物理過程: (1) 氣(qi)體的(de)(de)電離。(2) 粉(fen)(fen)塵的(de)(de)荷電。(3) 荷電粉(fen)(fen)塵向電極移動。(4) 荷電粉(fen)(fen)塵的(de)(de)捕集(ji)。
