銅川靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原(yuan)理是(shi)利用(yong)高壓電(dian)場(chang)使煙氣發生電(dian)離，氣流中的(de)粉塵(chen)荷(he)電(dian)在電(dian)場(chang)作(zuo)用(yong)下與氣流分(fen)離。負極由不同斷面形狀的(de)金屬(shu)導線制成，叫(jiao)放電(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)性能受粉塵(chen)性質、設備構造(zao)和煙氣(qi)流(liu)速等三個因(yin)素的(de)(de)影響。粉塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)(de)指標(biao)，它對除塵(chen)效率有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)粒(li)難以保持在(zai)集塵(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返(fan)氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)層之間形成電(dian)(dian)(dian)壓梯度會產(chan)生局部擊穿和放電(dian)(dian)(dian)現(xian)象。這些情況都(dou)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(zhi)100kV以上。

工作原理

電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)基本原(yuan)理(li)(li)是利用電(dian)(dian)(dian)(dian)(dian)力捕(bu)集煙氣中的(de)(de)(de)粉塵(chen)，主(zhu)要包括以下四(si)個相互有關的(de)(de)(de)物(wu)理(li)(li)過程：（1）氣體(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)離(li)。（2）粉塵(chen)的(de)(de)(de)荷(he)電(dian)(dian)(dian)(dian)(dian)。（3）荷(he)電(dian)(dian)(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)(dian)(dian)極移動。（4）荷(he)電(dian)(dian)(dian)(dian)(dian)粉塵(chen)的(de)(de)(de)捕(bu)集。

荷電(dian)粉塵(chen)的(de)(de)捕(bu)集過程(cheng)：在(zai)(zai)兩(liang)個曲率半徑相差較(jiao)大的(de)(de)金屬陽極(ji)和(he)陰極(ji)上(shang)，通(tong)過高壓直流(liu)電(dian)，維持一個足(zu)以使(shi)氣體電(dian)離的(de)(de)電(dian)場，氣體電(dian)離后所產生的(de)(de)電(dian)子(zi)：陰離子(zi)和(he)陽離子(zi)，吸附在(zai)(zai)通(tong)過電(dian)場的(de)(de)粉塵(chen)上(shang)，使(shi)粉塵(chen)獲得電(dian)荷。荷電(dian)極(ji)性(xing)不同(tong)的(de)(de)粉塵(chen)在(zai)(zai)電(dian)場力的(de)(de)作用下，分(fen)(fen)別向不同(tong)極(ji)性(xing)的(de)(de)電(dian)極(ji)運(yun)動，沉積(ji)在(zai)(zai)電(dian)極(ji)上(shang)，而達(da)到粉塵(chen)和(he)氣體分(fen)(fen)離的(de)(de)目的(de)(de)。
