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(wo)式靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化法(fa)來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的粉(fen)(fen)塵(chen)(chen)，它的凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和沉(chen)淀兩(liang)個系統來(lai)完成的，當(dang)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)(qi)流(liu)分(fen)布(bu)板以及折流(liu)板的調(diao)整后，使(shi)(shi)氣(qi)(qi)(qi)(qi)流(liu)能較均勻地進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)。在(zai)(zai)(zai)橫斷面擴大(da)的作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降低，其中(zhong)(zhong)有些較重的塵(chen)(chen)粒(li)便(bian)失去速度而(er)沉(chen)降下(xia)來(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的氣(qi)(qi)(qi)(qi)體(ti)中(zhong)(zhong)存在(zai)(zai)(zai)大(da)量的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的粉(fen)(fen)塵(chen)(chen)結合(he)起來(lai)，使(shi)(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)力的作用(yong)下(xia)趨向本(ben)設(she)(she)備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)(she)備采用(yong)負(fu)高壓制)和陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積在(zai)(zai)(zai)相應的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設(she)(she)備陰陽(yang)極(ji)(ji)(ji)振打系統的振打，使(shi)(shi)沉(chen)積在(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的粉(fen)(fen)塵(chen)(chen)振落，進人(ren)(ren)(ren)集灰斗 通過(guo)排灰裝置(zhi)放出(chu)，回收(shou)有物料，被)凈化的氣(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)除(chu)塵(chen)(chen)器的工作原理是利用高(gao)壓(ya)電(dian)(dian)場使煙(yan)氣(qi)發生(sheng)電(dian)(dian)離(li)，氣(qi)流中的粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作用下與氣(qi)流分(fen)離(li)。負極(ji)由不同斷面(mian)形狀的金屬導(dao)線(xian)制(zhi)成，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不同幾(ji)何形狀的金屬板制(zhi)成，叫集(ji)塵(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)器的性(xing)能受(shou)粉(fen)塵(chen)(chen)性(xing)質、設備構造(zao)(zao)和(he)煙(yan)氣(qi)流速等三個因(yin)素的影響(xiang)。粉(fen)塵(chen)(chen)的比(bi)電(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)性(xing)的指(zhi)標，它對除(chu)塵(chen)(chen)效率有直接的影響(xiang)。比(bi)電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒(li)難以(yi)保持在集(ji)塵(chen)(chen)電(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)流。比(bi)電(dian)(dian)阻(zu)過(guo)高(gao)，到達集(ji)塵(chen)(chen)電(dian)(dian)極(ji)的塵(chen)(chen)粒(li)電(dian)(dian)荷(he)不易放出，在塵(chen)(chen)層之間形成電(dian)(dian)壓(ya)梯度會(hui)產生(sheng)局(ju)部擊穿(chuan)和(he)放電(dian)(dian)現象(xiang)。這些情況(kuang)都會(hui)造(zao)(zao)成除(chu)塵(chen)(chen)效率下降(jiang)。

電除塵(chen)(chen)器(qi)的(de)(de)(de)基本原理(li)是利用電力捕集煙氣中(zhong)的(de)(de)(de)粉塵(chen)(chen)，主(zhu)要包括以下四(si)個相互有關的(de)(de)(de)物理(li)過程: (1) 氣體(ti)(ti)的(de)(de)(de)電離。(2) 粉塵(chen)(chen)的(de)(de)(de)荷(he)電。(3) 荷(he)電粉塵(chen)(chen)向電極(ji)移動(dong)。(4) 荷(he)電粉塵(chen)(chen)的(de)(de)(de)捕集。
