通化靜電除塵器廠家

靜電除塵器的工作原理(li)是(shi)利用高壓電場使煙氣發生電離，氣流中(zhong)的粉塵荷(he)電在電場作用下與氣流分離。負極由不同斷面(mian)形狀的金屬導(dao)線(xian)制成，叫放電電極。

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(neng)受粉塵(chen)(chen)(chen)性質、設(she)備構造和(he)煙氣流(liu)速(su)等三個因素的(de)影響。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻是評價導電(dian)(dian)性的(de)指標(biao)，它(ta)對除塵(chen)(chen)(chen)效率有直接的(de)影響。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)極上，致使其重返氣流(liu)。比(bi)電(dian)(dian)阻過高，到(dao)達集(ji)塵(chen)(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度(du)會(hui)產生局部擊穿和(he)放(fang)電(dian)(dian)現象。這些情況都會(hui)造成(cheng)除塵(chen)(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，靜電除塵器運行電壓(ya)需保持40一75kV乃至(zhi)100kV以上。

工作原理

電(dian)除塵(chen)(chen)器的(de)基本原(yuan)理(li)是利用電(dian)力捕集煙氣中的(de)粉(fen)(fen)塵(chen)(chen)，主要(yao)包括(kuo)以下四個相互(hu)有關(guan)的(de)物理(li)過程：（1）氣體的(de)電(dian)離。（2）粉(fen)(fen)塵(chen)(chen)的(de)荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)(fen)塵(chen)(chen)向(xiang)電(dian)極(ji)移動。（4）荷(he)電(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕集。

荷電(dian)(dian)粉(fen)塵的(de)(de)捕集過(guo)程：在(zai)兩個(ge)曲率半徑相差較大的(de)(de)金屬(shu)陽(yang)極和陰極上，通過(guo)高壓直(zhi)流電(dian)(dian)，維(wei)持一個(ge)足以(yi)使氣體電(dian)(dian)離的(de)(de)電(dian)(dian)場(chang)，氣體電(dian)(dian)離后所產生(sheng)的(de)(de)電(dian)(dian)子(zi)：陰離子(zi)和陽(yang)離子(zi)，吸附(fu)在(zai)通過(guo)電(dian)(dian)場(chang)的(de)(de)粉(fen)塵上，使粉(fen)塵獲得電(dian)(dian)荷。荷電(dian)(dian)極性不同(tong)(tong)的(de)(de)粉(fen)塵在(zai)電(dian)(dian)場(chang)力的(de)(de)作用下(xia)，分別向(xiang)不同(tong)(tong)極性的(de)(de)電(dian)(dian)極運(yun)動，沉(chen)積在(zai)電(dian)(dian)極上，而達(da)到(dao)粉(fen)塵和氣體分離的(de)(de)目的(de)(de)。
