佳木斯靜電除塵器廠家

靜電除塵器的工作原理是利(li)用(yong)高壓(ya)電場使煙氣(qi)(qi)發(fa)生電離，氣(qi)(qi)流(liu)中的粉塵(chen)荷電在電場作用(yong)下(xia)與氣(qi)(qi)流(liu)分離。負極(ji)由不同(tong)斷面(mian)形狀的金屬(shu)導線制成，叫放(fang)電電極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的(de)性(xing)能受粉(fen)塵性(xing)質(zhi)、設備構造和(he)煙(yan)氣(qi)流速等三個(ge)因素的(de)影響。粉(fen)塵的(de)比(bi)電(dian)阻是(shi)評價導電(dian)性(xing)的(de)指標，它對除塵效率有直接的(de)影響。比(bi)電(dian)阻過(guo)低，塵粒(li)難以保持在(zai)集塵電(dian)極上(shang)，致使其(qi)重(zhong)返氣(qi)流。比(bi)電(dian)阻過(guo)高，到達集塵電(dian)極的(de)塵粒(li)電(dian)荷不易放(fang)出，在(zai)塵層之間形成電(dian)壓梯度會產生局(ju)部擊穿和(he)放(fang)電(dian)現象。這(zhe)些情況都會造成除塵效率下(xia)降(jiang)。

簡介

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(xu)保(bao)持40一75kV乃至100kV以上(shang)。

工作原理

電(dian)(dian)(dian)除塵器(qi)的(de)基本原理是利用電(dian)(dian)(dian)力捕集(ji)煙氣中的(de)粉(fen)塵，主(zhu)要包括以下四個相互(hu)有關(guan)的(de)物(wu)理過程：（1）氣體(ti)的(de)電(dian)(dian)(dian)離(li)。（2）粉(fen)塵的(de)荷(he)電(dian)(dian)(dian)。（3）荷(he)電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極(ji)移動(dong)。（4）荷(he)電(dian)(dian)(dian)粉(fen)塵的(de)捕集(ji)。

荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕集過(guo)程：在兩個曲率半徑相差較大(da)的(de)金(jin)屬陽(yang)(yang)極(ji)(ji)(ji)和(he)陰極(ji)(ji)(ji)上，通過(guo)高壓直流電(dian)(dian)，維(wei)持一個足以使(shi)(shi)氣(qi)體電(dian)(dian)離(li)(li)的(de)電(dian)(dian)場(chang)，氣(qi)體電(dian)(dian)離(li)(li)后所產生的(de)電(dian)(dian)子：陰離(li)(li)子和(he)陽(yang)(yang)離(li)(li)子，吸附在通過(guo)電(dian)(dian)場(chang)的(de)粉(fen)(fen)塵(chen)(chen)上，使(shi)(shi)粉(fen)(fen)塵(chen)(chen)獲(huo)得(de)電(dian)(dian)荷。荷電(dian)(dian)極(ji)(ji)(ji)性(xing)不(bu)同的(de)粉(fen)(fen)塵(chen)(chen)在電(dian)(dian)場(chang)力的(de)作用(yong)下(xia)，分(fen)別向不(bu)同極(ji)(ji)(ji)性(xing)的(de)電(dian)(dian)極(ji)(ji)(ji)運動(dong)，沉積在電(dian)(dian)極(ji)(ji)(ji)上，而達(da)到粉(fen)(fen)塵(chen)(chen)和(he)氣(qi)體分(fen)離(li)(li)的(de)目的(de)。
