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。

臥式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化工作上要是(shi)依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀(dian)兩(liang)個系統(tong)來(lai)(lai)(lai)完成(cheng)的(de)(de)(de)(de)，當(dang)含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)(jin)(jin)人氣(qi)(qi)(qi)刺叭時，含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及折流(liu)板的(de)(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)能較均勻(yun)地進(jin)(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)作用下(xia)(xia)，氣(qi)(qi)(qi)流(liu)速度迅速降低，其(qi)中有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失(shi)去速度而沉降下(xia)(xia)來(lai)(lai)(lai)。進(jin)(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通人高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)子(zi)(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)子(zi)(zi)(zi)與進(jin)(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)(lai)(lai)，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)作用下(xia)(xia)趨向本設備(bei)(bei)陽極(ji)(正極(ji)、本設備(bei)(bei)采用負(fu)高壓制)和(he)陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分(fen)別沉積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設備(bei)(bei)陰陽極(ji)振(zhen)(zhen)打系統(tong)的(de)(de)(de)(de)振(zhen)(zhen)打，使(shi)沉積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)(jin)(jin)人集(ji)灰斗 通過排灰裝置放出，回收有物料(liao)，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的工作(zuo)原理是(shi)利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中的粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣(qi)(qi)流分離。負極(ji)由不同斷面形狀的金(jin)(jin)屬導(dao)線(xian)制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形狀的金(jin)(jin)屬板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質(zhi)、設(she)備構造(zao)和煙(yan)氣(qi)(qi)流速等三個因素的影響。粉(fen)塵(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評(ping)價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的指標，它對除塵(chen)(chen)(chen)效率有直(zhi)接(jie)的影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒(li)難以保持(chi)在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到(dao)達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產(chan)生局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情(qing)況(kuang)都會造(zao)成(cheng)除塵(chen)(chen)(chen)效率下降。

電除塵(chen)(chen)器的(de)(de)基本原(yuan)理是利用電力捕集煙(yan)氣中的(de)(de)粉塵(chen)(chen)，主(zhu)要包括(kuo)以下四個相(xiang)互有關的(de)(de)物(wu)理過程: (1) 氣體的(de)(de)電離。(2) 粉塵(chen)(chen)的(de)(de)荷電。(3) 荷電粉塵(chen)(chen)向(xiang)電極移(yi)動。(4) 荷電粉塵(chen)(chen)的(de)(de)捕集。
