許昌靜電除塵器廠家

靜電除塵器的工作原(yuan)理是利用(yong)高壓電(dian)場(chang)使(shi)煙(yan)氣發生電(dian)離，氣流中的粉塵荷(he)電(dian)在電(dian)場(chang)作用(yong)下(xia)與氣流分離。負極由(you)不(bu)同(tong)斷面(mian)形狀的金屬導線制成，叫放電(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)性(xing)能(neng)受粉塵(chen)性(xing)質(zhi)、設備(bei)構造和(he)煙氣(qi)流速等三(san)個(ge)因素的(de)影(ying)響。粉塵(chen)的(de)比(bi)(bi)電(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)性(xing)的(de)指標(biao)，它對除(chu)塵(chen)效(xiao)率有直(zhi)接的(de)影(ying)響。比(bi)(bi)電(dian)(dian)阻過低，塵(chen)粒(li)難以保持在集塵(chen)電(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流。比(bi)(bi)電(dian)(dian)阻過高，到達集塵(chen)電(dian)(dian)極(ji)的(de)塵(chen)粒(li)電(dian)(dian)荷不易(yi)放(fang)出，在塵(chen)層之間形成電(dian)(dian)壓梯度會(hui)(hui)產生(sheng)局部擊(ji)穿和(he)放(fang)電(dian)(dian)現(xian)象。這些情(qing)況都會(hui)(hui)造成除(chu)塵(chen)效(xiao)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(bao)持40一75kV乃至100kV以上。

工作原理

電(dian)除塵(chen)器的基本原理(li)是利用(yong)電(dian)力捕集煙氣中的粉塵(chen)，主(zhu)要(yao)包括以下四(si)個(ge)相(xiang)互(hu)有關的物理(li)過程：（1）氣體的電(dian)離(li)。（2）粉塵(chen)的荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)向電(dian)極移動。（4）荷(he)電(dian)粉塵(chen)的捕集。

荷(he)電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集(ji)過(guo)(guo)程(cheng)：在(zai)(zai)兩(liang)個曲率半徑相差較大(da)的(de)(de)金屬陽極(ji)和陰極(ji)上(shang)，通過(guo)(guo)高壓直流電(dian)，維持一個足以使氣(qi)體電(dian)離的(de)(de)電(dian)場，氣(qi)體電(dian)離后所產生(sheng)的(de)(de)電(dian)子(zi)(zi)(zi)：陰離子(zi)(zi)(zi)和陽離子(zi)(zi)(zi)，吸(xi)附在(zai)(zai)通過(guo)(guo)電(dian)場的(de)(de)粉(fen)塵(chen)(chen)上(shang)，使粉(fen)塵(chen)(chen)獲(huo)得電(dian)荷(he)。荷(he)電(dian)極(ji)性不(bu)同(tong)的(de)(de)粉(fen)塵(chen)(chen)在(zai)(zai)電(dian)場力的(de)(de)作用下，分別向(xiang)不(bu)同(tong)極(ji)性的(de)(de)電(dian)極(ji)運(yun)動，沉積在(zai)(zai)電(dian)極(ji)上(shang)，而達(da)到粉(fen)塵(chen)(chen)和氣(qi)體分離的(de)(de)目的(de)(de)。
