XWD型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)(chen)(chen)器是以靜(jing)電(dian)(dian)凈(jing)(jing)化法來收捕廢(fei)氣(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈(jing)(jing)化工作(zuo)上要是依靠電(dian)(dian)暈極(ji)和(he)(he)沉(chen)(chen)淀兩個(ge)系(xi)統(tong)來完(wan)成(cheng)的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)受到(dao)氣(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)調整(zheng)后(hou)，使(shi)(shi)氣(qi)(qi)流(liu)能(neng)較均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)場(chang)。在(zai)(zai)(zai)(zai)橫斷(duan)面擴大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)速度迅(xun)速降低，其中(zhong)有些較重的(de)(de)塵(chen)(chen)(chen)粒(li)便失去速度而沉(chen)(chen)降下來。進(jin)人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)暈極(ji)通人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)，則在(zai)(zai)(zai)(zai)電(dian)(dian)暈極(ji)附近(jin)產生(sheng)電(dian)(dian)暈現象(xiang)，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)體(ti)中(zhong)存在(zai)(zai)(zai)(zai)大(da)量(liang)的(de)(de)電(dian)(dian)子(zi)和(he)(he)離子(zi)，這(zhe)些電(dian)(dian)子(zi)和(he)(he)離子(zi)與進(jin)人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)結合(he)起來，使(shi)(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)(zai)(zai)電(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下趨向本設(she)備陽極(ji)(正極(ji)、本設(she)備采用(yong)負高(gao)壓(ya)制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積(ji)在(zai)(zai)(zai)(zai)相應的(de)(de)電(dian)(dian)極(ji)上，通過(guo)設(she)備陰陽極(ji)振打系(xi)統(tong)的(de)(de)振打，使(shi)(shi)沉(chen)(chen)積(ji)在(zai)(zai)(zai)(zai)陰陽電(dian)(dian)極(ji)上的(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)人(ren)(ren)集(ji)灰斗 通過(guo)排灰裝置(zhi)放(fang)出，回收有物料，被)凈(jing)(jing)化的(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作原理是利(li)用(yong)高壓(ya)(ya)電(dian)(dian)場使煙氣(qi)(qi)(qi)發生電(dian)(dian)離，氣(qi)(qi)(qi)流中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)在(zai)電(dian)(dian)場作用(yong)下與氣(qi)(qi)(qi)流分離。負(fu)極(ji)(ji)由不同(tong)斷面形(xing)狀的(de)(de)(de)金屬導線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何(he)形(xing)狀的(de)(de)(de)金屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)性(xing)質(zhi)、設(she)備構造和煙氣(qi)(qi)(qi)流速(su)等三個因素的(de)(de)(de)影響。粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)的(de)(de)(de)指(zhi)標(biao)，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)難(nan)以保持在(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)(qi)(qi)流。比(bi)電(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)電(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)壓(ya)(ya)梯度會(hui)產生局部擊穿和放電(dian)(dian)現(xian)象。這些(xie)情況都會(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)除塵(chen)器(qi)的(de)(de)(de)基(ji)本原理是利用電(dian)力捕集(ji)煙氣中的(de)(de)(de)粉塵(chen)，主要(yao)包括以下四個相互有關(guan)的(de)(de)(de)物理過程: (1) 氣體的(de)(de)(de)電(dian)離。(2) 粉塵(chen)的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)向(xiang)電(dian)極移動(dong)。(4) 荷電(dian)粉塵(chen)的(de)(de)(de)捕集(ji)。
