WESP由電暈線（陰極(ji)）、沉淀極(ji)（陽(yang)極(ji)）、絕緣箱和供電電源組(zu)成(cheng)

接通35-84千伏(fu)的(de)(de)(de)可(ke)調高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)后(hou)，使(shi)懸掛在器內的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)不斷發射出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)，把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)間(jian)部(bu)分氣體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離成正(zheng)負離子(zi)而(er)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，按照同性相斥、異性相吸的(de)(de)(de)原理(li)，荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)的(de)(de)(de)粉塵(chen)顆(ke)粒各(ge)自(zi)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)性相反(fan)的(de)(de)(de)方向(xiang)移動，正(zheng)離子(zi)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)移動，而(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)負離子(zi)則移向(xiang)沉(chen)淀(dian)陽(yang)極(ji)。分散在氣體(ti)(ti)中的(de)(de)(de)酸霧(wu)(wu)、粉塵(chen)等(deng)與帶負電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離子(zi)相碰撞而(er)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)作用下(xia)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)酸霧(wu)(wu)、粉塵(chen)等(deng)移向(xiang)沉(chen)淀(dian)陽(yang)極(ji)內壁(bi)上，靠(kao)自(zi)重和(he)間(jian)斷沖洗順壁(bi)而(er)下(xia)，使(shi)煙(yan)氣得(de)到(dao)凈化(hua)。
