焦作靜電除塵器廠家

靜電除塵器的工作(zuo)原理(li)是(shi)利用高壓電(dian)(dian)(dian)場使煙氣發(fa)生電(dian)(dian)(dian)離，氣流中(zhong)的粉(fen)塵荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用下與氣流分離。負極由不同斷面形(xing)狀的金屬導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。

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(xing)能受粉(fen)塵(chen)(chen)性(xing)質(zhi)、設備(bei)構造和煙氣(qi)流速等三個因素的影響。粉(fen)塵(chen)(chen)的比電(dian)阻(zu)是(shi)評價導電(dian)性(xing)的指標，它對除塵(chen)(chen)效率有直(zhi)接的影響。比電(dian)阻(zu)過低，塵(chen)(chen)粒(li)難(nan)以保持在(zai)集塵(chen)(chen)電(dian)極上，致(zhi)使其重(zhong)返氣(qi)流。比電(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)電(dian)極的塵(chen)(chen)粒(li)電(dian)荷不易(yi)放(fang)出，在(zai)塵(chen)(chen)層之間(jian)形(xing)成電(dian)壓梯度會產生局部擊穿和放(fang)電(dian)現象。這些(xie)情況(kuang)都會造成除塵(chen)(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(zhi)100kV以上。

工作原理

電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)基(ji)本原理(li)是利用(yong)電(dian)(dian)(dian)(dian)力(li)捕(bu)集(ji)(ji)煙氣(qi)中的(de)(de)粉(fen)(fen)塵(chen)，主要包括以下四個相互有(you)關(guan)的(de)(de)物(wu)理(li)過程：（1）氣(qi)體的(de)(de)電(dian)(dian)(dian)(dian)離。（2）粉(fen)(fen)塵(chen)的(de)(de)荷電(dian)(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)向(xiang)電(dian)(dian)(dian)(dian)極移動。（4）荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)捕(bu)集(ji)(ji)。

荷(he)(he)電(dian)粉(fen)(fen)(fen)塵(chen)(chen)的(de)(de)(de)(de)捕(bu)集過(guo)程：在兩個曲率半徑相差較大的(de)(de)(de)(de)金(jin)屬陽(yang)極(ji)(ji)和陰極(ji)(ji)上，通(tong)過(guo)高壓直(zhi)流電(dian)，維持一個足以(yi)使氣體電(dian)離(li)的(de)(de)(de)(de)電(dian)場(chang)，氣體電(dian)離(li)后所產(chan)生的(de)(de)(de)(de)電(dian)子(zi)：陰離(li)子(zi)和陽(yang)離(li)子(zi)，吸附(fu)在通(tong)過(guo)電(dian)場(chang)的(de)(de)(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)上，使粉(fen)(fen)(fen)塵(chen)(chen)獲得(de)電(dian)荷(he)(he)。荷(he)(he)電(dian)極(ji)(ji)性(xing)不同(tong)的(de)(de)(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)在電(dian)場(chang)力的(de)(de)(de)(de)作用下，分別向不同(tong)極(ji)(ji)性(xing)的(de)(de)(de)(de)電(dian)極(ji)(ji)運動(dong)，沉積在電(dian)極(ji)(ji)上，而達到粉(fen)(fen)(fen)塵(chen)(chen)和氣體分離(li)的(de)(de)(de)(de)目的(de)(de)(de)(de)。
