采用結構(gou)(gou)形(xing)式有同心圓式、管(guan)式和蜂窩式等三種。無(wu)論哪(na)種結構(gou)(gou)，其工作原理，即在(zai)金(jin)屬(shu)導線與金(jin)屬(shu)管(guan)壁(bi)〔或機板〕間施加高(gao)壓直流(liu)電，以維持足(zu)以使氣體(ti)產生電離的電場，使陰陽(yang)機之間形(xing)成(cheng)電暈區(qu) 。
理論(lun)依據
按電(dian)(dian)(dian)(dian)場理論，正離(li)(li)(li)子(zi)吸(xi)(xi)(xi)附(fu)于(yu)(yu)帶負(fu)電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)暈機(ji)(ji)(ji)(ji)(ji)，負(fu)離(li)(li)(li)子(zi)吸(xi)(xi)(xi)附(fu)于(yu)(yu)帶正電(dian)(dian)(dian)(dian)的(de)沉(chen)淀(dian)(dian)機(ji)(ji)(ji)(ji)(ji)；所(suo)(suo)有被電(dian)(dian)(dian)(dian)離(li)(li)(li)的(de)正負(fu)離(li)(li)(li)子(zi)均充滿電(dian)(dian)(dian)(dian)暈機(ji)(ji)(ji)(ji)(ji)與沉(chen)淀(dian)(dian)機(ji)(ji)(ji)(ji)(ji)之間的(de)整個空間。當含焦油(you)霧(wu)滴(di)等雜質的(de)煤氣通過該電(dian)(dian)(dian)(dian)場時，吸(xi)(xi)(xi)附(fu)了負(fu)離(li)(li)(li)子(zi)和電(dian)(dian)(dian)(dian)子(zi)的(de)雜質在電(dian)(dian)(dian)(dian)場庫倫力的(de)作用下，移動到(dao)沉(chen)淀(dian)(dian)機(ji)(ji)(ji)(ji)(ji)后釋(shi)放出所(suo)(suo)帶電(dian)(dian)(dian)(dian)荷，并吸(xi)(xi)(xi)附(fu)于(yu)(yu)沉(chen)淀(dian)(dian)機(ji)(ji)(ji)(ji)(ji)上，從而達到(dao)凈化氣體的(de)目的(de)，通常稱為荷電(dian)(dian)(dian)(dian)現象(xiang)。當吸(xi)(xi)(xi)附(fu)于(yu)(yu)沉(chen)淀(dian)(dian)機(ji)(ji)(ji)(ji)(ji)上的(de)雜質量(liang)增(zeng)加到(dao)大于(yu)(yu)其附(fu)著力時，會自動向下 流趟，從底部排出，凈(jing)氣體(ti)(ti)則從電捕焦油器上部離開并進入(ru)下道工序(xu)。
工作(zuo)機(ji)理
氣體的放電過(guo)程(cheng) ：在(zai)通常情(qing)況下氣(qi)體是不導電(dian)的(de)，但在(zai)高壓電(dian)場的(de)作用下氣(qi)體內部的(de)電(dian)子(zi)便(bian)會獲得足夠的(de)能 量成為自 由電(dian)(dian)(dian)(dian)子(zi)而導(dao)電(dian)(dian)(dian)(dian)，被稱為自發(fa)性(xing)電(dian)(dian)(dian)(dian)離(li)(li)現象。氣(qi)體(ti)的自發(fa)性(xing)電(dian)(dian)(dian)(dian)離(li)(li)是建立(li)在非均勻(yun)(yun)性(xing)電(dian)(dian)(dian)(dian)場(chang)(chang)中(zhong)。在均勻(yun)(yun)性(xing)電(dian)(dian)(dian)(dian)場(chang)(chang)中(zhong)，隨(sui)(sui)著電(dian)(dian)(dian)(dian)壓(ya)的增(zeng)加(jia)，只要其間任何一點(dian)發(fa)生電(dian)(dian)(dian)(dian)離(li)(li)，兩(liang)機(ji)間將立(li)即充滿帶電(dian)(dian)(dian)(dian)離(li)(li)子(zi)，整個空間的氣(qi)體(ti)被擊穿。此時電(dian)(dian)(dian)(dian)流急劇增(zeng)加(jia)而形成火花放(fang)電(dian)(dian)(dian)(dian)。而在非均勻(yun)(yun)性(xing)電(dian)(dian)(dian)(dian)場(chang)(chang)中(zhong)，電(dian)(dian)(dian)(dian)場(chang)(chang)強(qiang)度則隨(sui)(sui)兩(liang)機(ji)間的距(ju)離(li)(li)增(zeng) 大而迅速下降。
工業中的(de)選擇 ：根據供(gong)電(dian)(dian)機性的(de)不(bu)同，電(dian)(dian)暈(yun)(yun)(yun)有陰電(dian)(dian)暈(yun)(yun)(yun)和陽(yang)電(dian)(dian)暈(yun)(yun)(yun)之分。在(zai)工業生產中，大多采用陰電(dian)(dian)暈(yun)(yun)(yun)，因為在(zai)相(xiang)同的(de)條件下(xia)，陰電(dian)(dian)暈(yun)(yun)(yun)可以獲得(de)比陽(yang)電(dian)(dian)暈(yun)(yun)(yun)高的(de)電(dian)(dian)流，而(er)且其閃(shan)絡電(dian)(dian)壓也遠比陽(yang)電(dian)(dian)暈(yun)(yun)(yun)放電(dian)(dian)要高。
影(ying)響(xiang)電捕性能的(de)主要(yao)因素：
由于影響操(cao)作性能(neng)的因(yin)素很多，選型時請(qing)告知(zhi)粉塵與(yu)霧滴的密度(du)、粘度(du)、比電(dian)阻、氣體溫度(du)、壓力、濕(shi)度(du)、流速與(yu)雜濃(nong)度(du)等(deng)。
