海北靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原理是利用高壓電場(chang)使煙(yan)氣(qi)發生電離，氣(qi)流中的(de)粉(fen)塵荷電在電場(chang)作(zuo)用下與氣(qi)流分(fen)離。負極由不同(tong)斷面形狀的(de)金(jin)屬導線制成(cheng)，叫放(fang)電電極。

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(de)性能受粉塵性質、設備構造和煙氣流(liu)速等三(san)個因(yin)素(su)的(de)影響(xiang)。粉塵的(de)比電(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)性的(de)指(zhi)標，它(ta)對除塵效率(lv)(lv)有直接(jie)的(de)影響(xiang)。比電(dian)(dian)阻(zu)過低，塵粒(li)難以保持在集塵電(dian)(dian)極上(shang)，致使其重返氣流(liu)。比電(dian)(dian)阻(zu)過高，到達集塵電(dian)(dian)極的(de)塵粒(li)電(dian)(dian)荷不(bu)易放出(chu)，在塵層之(zhi)間形成電(dian)(dian)壓(ya)梯度會產(chan)生(sheng)局部擊穿和放電(dian)(dian)現(xian)象。這些情況都會造成除塵效率(lv)(lv)下(xia)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(bao)持40一75kV乃至100kV以上。

工作原理

電(dian)除塵器的(de)(de)基本原理(li)是利用電(dian)力捕集煙氣中的(de)(de)粉(fen)塵，主要包(bao)括以(yi)下四個相互有關的(de)(de)物(wu)理(li)過程：（1）氣體的(de)(de)電(dian)離(li)。（2）粉(fen)塵的(de)(de)荷電(dian)。（3）荷電(dian)粉(fen)塵向(xiang)電(dian)極移(yi)動。（4）荷電(dian)粉(fen)塵的(de)(de)捕集。

荷(he)電(dian)(dian)粉塵(chen)的(de)(de)捕集過程：在(zai)兩個曲(qu)率半(ban)徑(jing)相差較(jiao)大的(de)(de)金(jin)屬陽極和陰(yin)極上，通過高(gao)壓直流電(dian)(dian)，維持一個足以使氣體(ti)電(dian)(dian)離(li)(li)的(de)(de)電(dian)(dian)場(chang)，氣體(ti)電(dian)(dian)離(li)(li)后所產生的(de)(de)電(dian)(dian)子(zi)：陰(yin)離(li)(li)子(zi)和陽離(li)(li)子(zi)，吸附在(zai)通過電(dian)(dian)場(chang)的(de)(de)粉塵(chen)上，使粉塵(chen)獲(huo)得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極性(xing)不同的(de)(de)粉塵(chen)在(zai)電(dian)(dian)場(chang)力(li)的(de)(de)作用下，分(fen)別(bie)向(xiang)不同極性(xing)的(de)(de)電(dian)(dian)極運(yun)動，沉積(ji)在(zai)電(dian)(dian)極上，而達到粉塵(chen)和氣體(ti)分(fen)離(li)(li)的(de)(de)目的(de)(de)。
