阜新靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利用高(gao)壓電(dian)場使煙氣(qi)發(fa)生電(dian)離，氣(qi)流中(zhong)的粉塵荷電(dian)在電(dian)場作(zuo)用下與氣(qi)流分離。負極(ji)由不同斷面形狀的金屬(shu)導線(xian)制成(cheng)，叫放(fang)電(dian)電(dian)極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能受粉塵(chen)性質、設備構造(zao)和(he)煙氣(qi)流速等三個因素的影響。粉塵(chen)的比(bi)(bi)(bi)電(dian)(dian)阻是評(ping)價導電(dian)(dian)性的指標，它對除塵(chen)效率有直接的影響。比(bi)(bi)(bi)電(dian)(dian)阻過(guo)低(di)，塵(chen)粒(li)難以保(bao)持在(zai)集塵(chen)電(dian)(dian)極上，致使其重返氣(qi)流。比(bi)(bi)(bi)電(dian)(dian)阻過(guo)高，到(dao)達集塵(chen)電(dian)(dian)極的塵(chen)粒(li)電(dian)(dian)荷不易放(fang)(fang)出，在(zai)塵(chen)層之間形成電(dian)(dian)壓梯度會產(chan)生局部擊穿和(he)放(fang)(fang)電(dian)(dian)現象。這些情況都會造(zao)成除塵(chen)效率下降。

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保持40一75kV乃至100kV以上(shang)。

工作原理

電(dian)除塵(chen)器的(de)基本(ben)原(yuan)理是利用電(dian)力(li)捕集煙氣中的(de)粉(fen)塵(chen)，主要(yao)包(bao)括以下(xia)四(si)個相互有關(guan)的(de)物理過程：（1）氣體的(de)電(dian)離。（2）粉(fen)塵(chen)的(de)荷電(dian)。（3）荷電(dian)粉(fen)塵(chen)向電(dian)極移動(dong)。（4）荷電(dian)粉(fen)塵(chen)的(de)捕集。

荷電(dian)(dian)(dian)粉(fen)塵的(de)捕集(ji)過(guo)程：在(zai)兩個曲率半(ban)徑相差較大的(de)金屬陽極(ji)和陰極(ji)上(shang)(shang)，通(tong)(tong)過(guo)高壓(ya)直流電(dian)(dian)(dian)，維(wei)持一(yi)個足(zu)以使氣(qi)體(ti)電(dian)(dian)(dian)離的(de)電(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)離后所(suo)產生的(de)電(dian)(dian)(dian)子(zi)(zi)：陰離子(zi)(zi)和陽離子(zi)(zi)，吸(xi)附(fu)在(zai)通(tong)(tong)過(guo)電(dian)(dian)(dian)場的(de)粉(fen)塵上(shang)(shang)，使粉(fen)塵獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)性不同的(de)粉(fen)塵在(zai)電(dian)(dian)(dian)場力的(de)作用下，分(fen)別向不同極(ji)性的(de)電(dian)(dian)(dian)極(ji)運動，沉積(ji)在(zai)電(dian)(dian)(dian)極(ji)上(shang)(shang)，而達(da)到粉(fen)塵和氣(qi)體(ti)分(fen)離的(de)目的(de)。
