正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器的性能受粉塵性質、設備構造和煙氣流速等三個因素的影響。粉塵的比電阻是評價導電性的指標，它對除塵效率有直接的影響。比電阻過低，塵粒難以保持在集塵電極上，致使其重返氣流。比電阻過高，到達集塵電極的塵粒電荷不易放出，在塵層之間形成電壓梯度會產生局部擊穿和放電現象。這些情況都會造成除塵效率下降。

靜電除塵器的電源由控制箱、升壓變壓器和整流器組成。電源輸出的電壓高低對除塵效率也有很大影響。因此，靜電除塵器運行電壓需保持40一75kV乃至100kV以上。

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)運行(xing)電(dian)(dian)(dian)壓需(xu)保持40一75kV乃至(zhi)100kV以上。正(zheng)極(ji)由(you)(you)不同(tong)幾(ji)何形狀(zhuang)的(de)(de)(de)(de)金(jin)屬板制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)(qi)流(liu)速等三個因(yin)素的(de)(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)阻(zu)(zu)(zu)是(shi)評(ping)價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標(biao)，它(ta)對除(chu)(chu)塵(chen)(chen)效率(lv)有直接的(de)(de)(de)(de)影響。比電(dian)(dian)(dian)阻(zu)(zu)(zu)過低(di)，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其(qi)重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)阻(zu)(zu)(zu)過高(gao)，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷(he)(he)不易放出，在塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿和放電(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)效率(lv)下降。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)工作原理(li)是(shi)利用(yong)(yong)高(gao)壓電(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用(yong)(yong)下與(yu)氣(qi)(qi)流(liu)分離。負極(ji)由(you)(you)不同(tong)斷面形狀(zhuang)的(de)(de)(de)(de)金(jin)屬導線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。
