隨州靜電除塵器廠家

靜電除塵器的工(gong)作原理是利用高壓電場使(shi)煙(yan)氣發(fa)生電離(li)，氣流中(zhong)的粉(fen)塵荷電在電場作用下與氣流分離(li)。負(fu)極由不同斷面形狀的金屬導線制(zhi)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(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設(she)備構(gou)造和煙氣(qi)流速等三個(ge)因素的(de)影響。粉(fen)塵(chen)(chen)的(de)比電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性(xing)的(de)指(zhi)標，它(ta)對(dui)除塵(chen)(chen)效率有直接(jie)的(de)影響。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難以(yi)保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致使其(qi)重返氣(qi)流。比電(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)壓梯度(du)會(hui)產生局部擊穿和放電(dian)(dian)(dian)現象。這(zhe)些情況都會(hui)造成除塵(chen)(chen)效率下(xia)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(zhi)100kV以上。

工作原理

電(dian)(dian)除塵(chen)器的(de)基本原(yuan)理是利用電(dian)(dian)力捕集煙氣中的(de)粉(fen)塵(chen)，主(zhu)要包括以下四個(ge)相互有關的(de)物理過程：（1）氣體的(de)電(dian)(dian)離。（2）粉(fen)塵(chen)的(de)荷(he)(he)電(dian)(dian)。（3）荷(he)(he)電(dian)(dian)粉(fen)塵(chen)向(xiang)電(dian)(dian)極移動。（4）荷(he)(he)電(dian)(dian)粉(fen)塵(chen)的(de)捕集。

荷電(dian)(dian)粉(fen)(fen)塵(chen)的(de)捕(bu)集過程：在(zai)兩個曲率半(ban)徑相差較大的(de)金屬(shu)陽(yang)極(ji)和(he)陰極(ji)上，通(tong)過高(gao)壓直流電(dian)(dian)，維(wei)持一個足以(yi)使氣體電(dian)(dian)離(li)的(de)電(dian)(dian)場，氣體電(dian)(dian)離(li)后所產生的(de)電(dian)(dian)子(zi)(zi)：陰離(li)子(zi)(zi)和(he)陽(yang)離(li)子(zi)(zi)，吸附(fu)在(zai)通(tong)過電(dian)(dian)場的(de)粉(fen)(fen)塵(chen)上，使粉(fen)(fen)塵(chen)獲得電(dian)(dian)荷。荷電(dian)(dian)極(ji)性不同的(de)粉(fen)(fen)塵(chen)在(zai)電(dian)(dian)場力(li)的(de)作(zuo)用下，分(fen)別向不同極(ji)性的(de)電(dian)(dian)極(ji)運動(dong)，沉積在(zai)電(dian)(dian)極(ji)上，而達到粉(fen)(fen)塵(chen)和(he)氣體分(fen)離(li)的(de)目(mu)的(de)。
