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。

臥式靜電除塵(chen)(chen)(chen)(chen)器是以靜電凈化(hua)法來收捕廢氣(qi)(qi)中(zhong)的(de)粉塵(chen)(chen)(chen)(chen)，它(ta)的(de)凈化(hua)工作(zuo)上(shang)要是依(yi)靠(kao)電暈(yun)極(ji)和(he)(he)沉淀兩個(ge)系統來完成的(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)能較均(jun)勻地進(jin)人電場(chang)。在(zai)(zai)橫斷面擴大(da)的(de)作(zuo)用下，氣(qi)(qi)流(liu)速(su)度迅速(su)降低，其中(zhong)有些較重的(de)塵(chen)(chen)(chen)(chen)粒便(bian)失去速(su)度而沉降下來。進(jin)人電場(chang)的(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電暈(yun)極(ji)通人高壓(ya)直流(liu)電，則在(zai)(zai)電暈(yun)極(ji)附近(jin)產生(sheng)電暈(yun)現象，使(shi)(shi)氣(qi)(qi)體(ti)電離，電離后的(de)氣(qi)(qi)體(ti)中(zhong)存在(zai)(zai)大(da)量的(de)電子(zi)(zi)(zi)和(he)(he)離子(zi)(zi)(zi)，這些電子(zi)(zi)(zi)和(he)(he)離子(zi)(zi)(zi)與進(jin)人電場(chang)的(de)粉塵(chen)(chen)(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)(chen)(chen)粒帶電，帶電塵(chen)(chen)(chen)(chen)粒在(zai)(zai)電場(chang)力的(de)作(zuo)用下趨向本(ben)設備陽極(ji)(正極(ji)、本(ben)設備采用負高壓(ya)制)和(he)(he)陰(yin)極(ji)(負極(ji)) ， 釋放(fang)(fang)出(chu)電子(zi)(zi)(zi)分(fen)別沉積(ji)在(zai)(zai)相(xiang)應(ying)的(de)電極(ji)上(shang)，通過(guo)設備陰(yin)陽極(ji)振(zhen)打系統的(de)振(zhen)打，使(shi)(shi)沉積(ji)在(zai)(zai)陰(yin)陽電極(ji)上(shang)的(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人集(ji)灰(hui)斗(dou) 通過(guo)排灰(hui)裝置放(fang)(fang)出(chu)，回收有物(wu)料(liao)，被)凈化(hua)的(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)工作原(yuan)理(li)是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)(qi)流中的(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作用下(xia)(xia)與氣(qi)(qi)(qi)流分離(li)。負極由(you)不同(tong)斷面形(xing)狀的(de)金(jin)屬(shu)導線制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極。正極由(you)不同(tong)幾何形(xing)狀的(de)金(jin)屬(shu)板制成，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)性(xing)能受(shou)粉塵(chen)(chen)性(xing)質(zhi)、設備構造(zao)和煙氣(qi)(qi)(qi)流速等三個因(yin)素的(de)影響(xiang)(xiang)。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)效率有(you)直(zhi)接的(de)影響(xiang)(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)粒(li)難以保(bao)持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極上，致使(shi)其重返氣(qi)(qi)(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成除塵(chen)(chen)效率下(xia)(xia)降(jiang)。

電(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)基本原理(li)是利用電(dian)力捕(bu)集煙氣(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)，主(zhu)要包括以下四個相(xiang)互有關的(de)(de)(de)物理(li)過(guo)程: (1) 氣(qi)體(ti)(ti)的(de)(de)(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)(chen)(chen)(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)捕(bu)集。
