電捕(bu)焦油器與機械除焦油器相比，具有捕(bu)焦油效率高、阻力損(sun)失小(xiao)、氣(qi)(qi)體處理量大等特(te)點．不(bu)僅可保證(zheng)后續(xu)工序對氣(qi)(qi)體質量的要求．提高產品回收率，而且可明顯改善操作環境。

按電(dian)(dian)(dian)場(chang)(chang)理論， 正離子(zi)(zi)吸(xi)附(fu)于(yu)帶(dai)負電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)暈極(ji)(ji)，負離子(zi)(zi)吸(xi)附(fu)于(yu)帶(dai)正電(dian)(dian)(dian)的(de)(de)沉淀(dian)(dian)極(ji)(ji)；所(suo)有(you)被電(dian)(dian)(dian)離的(de)(de)正負離子(zi)(zi)均(jun)充滿電(dian)(dian)(dian)暈極(ji)(ji)與沉淀(dian)(dian)極(ji)(ji)之間(jian)的(de)(de)整(zheng)個(ge)空間(jian)。當含焦油(you)霧滴等雜質的(de)(de)煤氣(qi)(qi)通(tong)過該電(dian)(dian)(dian)場(chang)(chang)時(shi)，吸(xi)附(fu)了負離子(zi)(zi)和電(dian)(dian)(dian)子(zi)(zi)的(de)(de)雜質在電(dian)(dian)(dian)場(chang)(chang)庫(ku)倫(lun)力的(de)(de)作用下，移動(dong)(dong)到(dao)沉淀(dian)(dian)極(ji)(ji)后釋放出(chu)所(suo)帶(dai)電(dian)(dian)(dian)荷，并吸(xi)附(fu)于(yu)沉淀(dian)(dian)極(ji)(ji)上，從而達到(dao)凈(jing)化氣(qi)(qi)體(ti)的(de)(de)目的(de)(de)，通(tong)常稱(cheng)為(wei)荷電(dian)(dian)(dian)現象。當吸(xi)附(fu)于(yu)沉淀(dian)(dian)極(ji)(ji)上的(de)(de)雜質量增加到(dao)大于(yu)其附(fu)著力時(shi)，會自動(dong)(dong)向下流趟(tang)，從電(dian)(dian)(dian)捕(bu)焦油(you)器底部(bu)排出(chu)，凈(jing)氣(qi)(qi)體(ti)則從電(dian)(dian)(dian)捕(bu)焦油(you)器上部(bu)離開并進入下道工序(xu)。
