重慶靜電除塵器廠家

靜電除塵器的(de)(de)工作原理是(shi)利用高壓(ya)電(dian)場使(shi)煙氣(qi)(qi)發(fa)生電(dian)離，氣(qi)(qi)流中的(de)(de)粉塵(chen)荷(he)電(dian)在電(dian)場作用下與氣(qi)(qi)流分離。負(fu)極由不同斷面形狀的(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)電(dian)電(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(de)(de)性(xing)能(neng)受粉塵(chen)(chen)性(xing)質、設(she)備構造(zao)和煙氣流速等三個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比電(dian)阻是評價導電(dian)性(xing)的(de)(de)指標，它(ta)對除塵(chen)(chen)效率有直(zhi)接(jie)的(de)(de)影響(xiang)。比電(dian)阻過低，塵(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)電(dian)極上(shang)，致使其重返氣流。比電(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)極的(de)(de)塵(chen)(chen)粒(li)電(dian)荷不易放出，在塵(chen)(chen)層之間形成(cheng)電(dian)壓梯度會(hui)產(chan)生局部(bu)擊穿和放電(dian)現象。這(zhe)些(xie)情況(kuang)都會(hui)造(zao)成(cheng)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(yun)行電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)基本原(yuan)理(li)是利用電(dian)(dian)(dian)(dian)力捕(bu)集煙(yan)氣中的(de)粉塵(chen)，主(zhu)要包括(kuo)以下四個相互有(you)關的(de)物理(li)過程(cheng)：（1）氣體的(de)電(dian)(dian)(dian)(dian)離。（2）粉塵(chen)的(de)荷電(dian)(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)(dian)(dian)極(ji)移(yi)動。（4）荷電(dian)(dian)(dian)(dian)粉塵(chen)的(de)捕(bu)集。

荷(he)電(dian)粉塵的(de)捕集過(guo)程：在(zai)兩個曲(qu)率半(ban)徑相差較大的(de)金(jin)屬(shu)陽(yang)極(ji)(ji)和陰極(ji)(ji)上，通(tong)過(guo)高壓直流電(dian)，維持一個足(zu)以使氣體電(dian)離的(de)電(dian)場(chang)，氣體電(dian)離后所產生的(de)電(dian)子(zi)：陰離子(zi)和陽(yang)離子(zi)，吸附(fu)在(zai)通(tong)過(guo)電(dian)場(chang)的(de)粉塵上，使粉塵獲(huo)得電(dian)荷(he)。荷(he)電(dian)極(ji)(ji)性不(bu)同的(de)粉塵在(zai)電(dian)場(chang)力的(de)作用(yong)下，分別向(xiang)不(bu)同極(ji)(ji)性的(de)電(dian)極(ji)(ji)運動，沉積(ji)在(zai)電(dian)極(ji)(ji)上，而達到粉塵和氣體分離的(de)目的(de)。
