    氣(qi)(qi)體(ti)的(de)(de)放電(dian)(dian)(dian)(dian)過程 ：在通常情況下(xia)(xia)氣(qi)(qi)體(ti)是不導電(dian)(dian)(dian)(dian)的(de)(de)，但在高壓電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)作用下(xia)(xia)氣(qi)(qi)體(ti)內部的(de)(de)電(dian)(dian)(dian)(dian)子(zi)便(bian)會獲得足夠的(de)(de)能量成(cheng)為自由電(dian)(dian)(dian)(dian)子(zi)而導電(dian)(dian)(dian)(dian)，被稱為自發性(xing)電(dian)(dian)(dian)(dian)離現象(xiang)。氣(qi)(qi)體(ti)的(de)(de)自發性(xing)電(dian)(dian)(dian)(dian)離是建(jian)立在非均勻性(xing)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)中。在均勻性(xing)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)中，隨著電(dian)(dian)(dian)(dian)壓的(de)(de)增加(jia)，只(zhi)要其(qi)間(jian)任何一點發生電(dian)(dian)(dian)(dian)離，兩極間(jian)將立即充滿帶電(dian)(dian)(dian)(dian)離子(zi)，整個空間(jian)的(de)(de)氣(qi)(qi)體(ti)被擊穿。此(ci)時電(dian)(dian)(dian)(dian)流(liu)急劇增加(jia)而形(xing)成(cheng)火花放電(dian)(dian)(dian)(dian)。而在非均勻性(xing)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)中，電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)強度則隨兩極間(jian)的(de)(de)距(ju)離增大(da)而迅速下(xia)(xia)降。

    工業(ye)中的(de)選(xuan)擇(ze) ：根據供電(dian)(dian)(dian)極性的(de)不(bu)同，電(dian)(dian)(dian)暈(yun)(yun)(yun)有(you)陰(yin)電(dian)(dian)(dian)暈(yun)(yun)(yun)和陽(yang)電(dian)(dian)(dian)暈(yun)(yun)(yun)之(zhi)分(fen)。在工業(ye)生產中，大(da)多采用陰(yin)電(dian)(dian)(dian)暈(yun)(yun)(yun)，因為在相(xiang)同的(de)條件下，陰(yin)電(dian)(dian)(dian)暈(yun)(yun)(yun)可以(yi)獲得比陽(yang)電(dian)(dian)(dian)暈(yun)(yun)(yun)高的(de)電(dian)(dian)(dian)流，而且其(qi)閃(shan)絡電(dian)(dian)(dian)壓也遠比陽(yang)電(dian)(dian)(dian)暈(yun)(yun)(yun)放電(dian)(dian)(dian)要高。

結(jie)構電(dian)(dian)捕焦(jiao)油(you)器由電(dian)(dian)捕焦(jiao)油(you)器主(zhu)體和供給高壓直流(liu)電(dian)(dian)的整流(liu)設(she)(she)備組成。電(dian)(dian)捕焦(jiao)油(you)器均由筒(tong)(tong)體、沉淀(dian)極、電(dian)(dian)暈極和電(dian)(dian)氣(qi)(qi)(qi)絕緣箱四大部分組成。筒(tong)(tong)體是圓筒(tong)(tong)形(xing)的(內徑根據煤氣(qi)(qi)(qi)流(liu)量決定)，并帶有(you)封頭，筒(tong)(tong)體上部設(she)(she)有(you)出氣(qi)(qi)(qi)管(guan)(guan)，下部設(she)(she)有(you)進氣(qi)(qi)(qi)管(guan)(guan)，并設(she)(she)有(you)兩個(ge)人孔和一個(ge)防(fang)爆閥。
