崇左靜電除塵器廠家

靜電除塵器的(de)(de)工作原理是利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)場(chang)使煙氣發(fa)生電(dian)(dian)(dian)離，氣流中的(de)(de)粉塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用(yong)下與氣流分離。負極(ji)由不同斷面形狀(zhuang)的(de)(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。

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(neng)受粉塵(chen)(chen)性質、設備構造和煙氣(qi)流(liu)速等三個因素的(de)影(ying)響。粉塵(chen)(chen)的(de)比(bi)電(dian)(dian)阻(zu)是評價導電(dian)(dian)性的(de)指標，它對除塵(chen)(chen)效率有直接的(de)影(ying)響。比(bi)電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒(li)(li)難以保持在(zai)集塵(chen)(chen)電(dian)(dian)極(ji)(ji)上，致(zhi)使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒(li)(li)電(dian)(dian)荷不易(yi)放出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)壓梯度(du)會產生局部(bu)擊穿和放電(dian)(dian)現象。這些情(qing)況都(dou)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(yun)行電(dian)壓需保持40一75kV乃至(zhi)100kV以上(shang)。

工作原理

電(dian)(dian)(dian)除塵器的(de)基本原(yuan)理(li)是(shi)利用電(dian)(dian)(dian)力捕(bu)集(ji)煙氣中(zhong)的(de)粉(fen)塵，主(zhu)要(yao)包括以(yi)下四個相互有(you)關(guan)的(de)物理(li)過程：（1）氣體的(de)電(dian)(dian)(dian)離(li)。（2）粉(fen)塵的(de)荷(he)(he)電(dian)(dian)(dian)。（3）荷(he)(he)電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極(ji)移(yi)動(dong)。（4）荷(he)(he)電(dian)(dian)(dian)粉(fen)塵的(de)捕(bu)集(ji)。

荷(he)(he)電(dian)(dian)(dian)粉(fen)塵的(de)(de)(de)(de)捕集(ji)過(guo)程(cheng)：在兩(liang)個曲率(lv)半徑相差(cha)較大的(de)(de)(de)(de)金屬陽極和陰(yin)極上，通(tong)過(guo)高壓直流電(dian)(dian)(dian)，維(wei)持(chi)一個足(zu)以(yi)使(shi)氣(qi)(qi)體電(dian)(dian)(dian)離的(de)(de)(de)(de)電(dian)(dian)(dian)場(chang)，氣(qi)(qi)體電(dian)(dian)(dian)離后所產生(sheng)的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)：陰(yin)離子(zi)(zi)和陽離子(zi)(zi)，吸(xi)附在通(tong)過(guo)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵上，使(shi)粉(fen)塵獲得電(dian)(dian)(dian)荷(he)(he)。荷(he)(he)電(dian)(dian)(dian)極性不同的(de)(de)(de)(de)粉(fen)塵在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用下，分別向不同極性的(de)(de)(de)(de)電(dian)(dian)(dian)極運動，沉積在電(dian)(dian)(dian)極上，而達(da)到(dao)粉(fen)塵和氣(qi)(qi)體分離的(de)(de)(de)(de)目的(de)(de)(de)(de)。
