    氣體(ti)(ti)的(de)(de)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程 ：在(zai)通常(chang)情況下氣體(ti)(ti)是(shi)不(bu)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)，但在(zai)高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)作用(yong)下氣體(ti)(ti)內部的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子便會(hui)獲得足夠的(de)(de)能(neng)量成為自(zi)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子而導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，被(bei)稱為自(zi)發性電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)現象。氣體(ti)(ti)的(de)(de)自(zi)發性電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)是(shi)建立在(zai)非均勻性電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場中(zhong)。在(zai)均勻性電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場中(zhong)，隨(sui)著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)增(zeng)加，只(zhi)要其間任何一點發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，兩極間將(jiang)立即(ji)充(chong)滿(man)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)子，整個空間的(de)(de)氣體(ti)(ti)被(bei)擊穿。此時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流急(ji)劇(ju)增(zeng)加而形成火花放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。而在(zai)非均勻性電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場中(zhong)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場強度則隨(sui)兩極間的(de)(de)距離(li)(li)增(zeng)大而迅速下降。

    工(gong)業(ye)中的選擇 ：根據(ju)供電(dian)(dian)(dian)極(ji)性的不同，電(dian)(dian)(dian)暈(yun)(yun)(yun)有陰電(dian)(dian)(dian)暈(yun)(yun)(yun)和(he)陽(yang)電(dian)(dian)(dian)暈(yun)(yun)(yun)之分。在工(gong)業(ye)生產(chan)中，大多采(cai)用陰電(dian)(dian)(dian)暈(yun)(yun)(yun)，因為在相(xiang)同的條件下，陰電(dian)(dian)(dian)暈(yun)(yun)(yun)可以獲得比陽(yang)電(dian)(dian)(dian)暈(yun)(yun)(yun)高的電(dian)(dian)(dian)流，而且其閃(shan)絡電(dian)(dian)(dian)壓也(ye)遠比陽(yang)電(dian)(dian)(dian)暈(yun)(yun)(yun)放電(dian)(dian)(dian)要(yao)高。

結構電(dian)捕焦(jiao)(jiao)油器由電(dian)捕焦(jiao)(jiao)油器主體和(he)供給高壓直(zhi)流電(dian)的整流設備組(zu)成。電(dian)捕焦(jiao)(jiao)油器均由筒(tong)體、沉淀極(ji)、電(dian)暈極(ji)和(he)電(dian)氣(qi)絕緣箱四大部分組(zu)成。筒(tong)體是圓筒(tong)形的(內徑根據煤氣(qi)流量決定)，并(bing)帶有(you)(you)封頭，筒(tong)體上部設有(you)(you)出氣(qi)管，下部設有(you)(you)進(jin)氣(qi)管，并(bing)設有(you)(you)兩個(ge)人孔(kong)和(he)一(yi)個(ge)防爆閥。
