沈陽靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利用高壓(ya)電(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中的粉塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分離。負極由(you)不(bu)同斷面形狀的金屬導線制成(cheng)，叫(jiao)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能受(shou)粉(fen)塵性質、設備(bei)構造和(he)(he)煙氣流速等三(san)個因素的影響(xiang)。粉(fen)塵的比(bi)電(dian)阻是評價導電(dian)性的指標，它對除塵效率有直(zhi)接的影響(xiang)。比(bi)電(dian)阻過(guo)低，塵粒(li)難(nan)以(yi)保持(chi)在集塵電(dian)極(ji)上(shang)，致使(shi)其重返氣流。比(bi)電(dian)阻過(guo)高，到達集塵電(dian)極(ji)的塵粒(li)電(dian)荷不易放出(chu)，在塵層之間(jian)形成電(dian)壓梯度會產生(sheng)局部擊穿(chuan)和(he)(he)放電(dian)現(xian)象(xiang)。這些情況都(dou)會造成除塵效率下降。

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(bao)持40一75kV乃(nai)至100kV以上。

工作原理

電(dian)除塵器的基本原理是(shi)利用電(dian)力捕集(ji)煙氣中的粉(fen)塵，主(zhu)要包括(kuo)以下(xia)四個(ge)相互有關的物理過程：（1）氣體(ti)的電(dian)離。（2）粉(fen)塵的荷電(dian)。（3）荷電(dian)粉(fen)塵向電(dian)極移動。（4）荷電(dian)粉(fen)塵的捕集(ji)。

荷(he)電(dian)(dian)粉(fen)(fen)(fen)(fen)塵(chen)(chen)(chen)的捕集過程：在(zai)兩個曲率(lv)半徑相(xiang)差較大的金屬陽(yang)極(ji)(ji)(ji)(ji)和(he)陰極(ji)(ji)(ji)(ji)上，通(tong)過高壓直(zhi)流電(dian)(dian)，維持(chi)一(yi)個足(zu)以使氣體(ti)電(dian)(dian)離(li)的電(dian)(dian)場(chang)，氣體(ti)電(dian)(dian)離(li)后所產(chan)生的電(dian)(dian)子：陰離(li)子和(he)陽(yang)離(li)子，吸附在(zai)通(tong)過電(dian)(dian)場(chang)的粉(fen)(fen)(fen)(fen)塵(chen)(chen)(chen)上，使粉(fen)(fen)(fen)(fen)塵(chen)(chen)(chen)獲(huo)得(de)電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)(ji)(ji)(ji)性(xing)(xing)不同的粉(fen)(fen)(fen)(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)場(chang)力的作用下，分別向(xiang)不同極(ji)(ji)(ji)(ji)性(xing)(xing)的電(dian)(dian)極(ji)(ji)(ji)(ji)運動，沉積(ji)在(zai)電(dian)(dian)極(ji)(ji)(ji)(ji)上，而達到(dao)粉(fen)(fen)(fen)(fen)塵(chen)(chen)(chen)和(he)氣體(ti)分離(li)的目的。
