臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥式靜電(dian)(dian)除塵(chen)(chen)(chen)器(qi)是以靜電(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)化工作上(shang)要(yao)是依(yi)靠(kao)電(dian)(dian)暈極和(he)沉(chen)淀兩個系統來(lai)完成(cheng)的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分(fen)布板以及折(zhe)流(liu)板的(de)(de)(de)(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)流(liu)能較(jiao)(jiao)均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)場(chang)(chang)。在橫斷(duan)面擴大的(de)(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)流(liu)速(su)(su)度(du)迅速(su)(su)降低(di)，其中(zhong)(zhong)有些(xie)較(jiao)(jiao)重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去(qu)速(su)(su)度(du)而沉(chen)降下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈極通(tong)人(ren)高壓(ya)直(zhi)流(liu)電(dian)(dian)，則在電(dian)(dian)暈極附近產生電(dian)(dian)暈現象，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在大量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)子(zi)和(he)離子(zi)，這些(xie)電(dian)(dian)子(zi)和(he)離子(zi)與進(jin)(jin)人(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)作用下趨(qu)向本設(she)備陽(yang)(yang)極(正(zheng)極、本設(she)備采用負(fu)高壓(ya)制)和(he)陰極(負(fu)極) ， 釋放(fang)出電(dian)(dian)子(zi)分(fen)別沉(chen)積在相應的(de)(de)(de)(de)(de)電(dian)(dian)極上(shang)，通(tong)過設(she)備陰陽(yang)(yang)極振(zhen)打(da)系統的(de)(de)(de)(de)(de)振(zhen)打(da)，使沉(chen)積在陰陽(yang)(yang)電(dian)(dian)極上(shang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通(tong)過排(pai)灰裝置放(fang)出，回收有物料，被)凈(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)工(gong)作(zuo)原(yuan)理是(shi)利用高(gao)壓(ya)電(dian)(dian)(dian)場使(shi)(shi)煙(yan)氣發生電(dian)(dian)(dian)離(li)，氣流中(zhong)的(de)(de)(de)粉塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用下與氣流分離(li)。負極(ji)由不同斷面形(xing)狀(zhuang)的(de)(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同幾何形(xing)狀(zhuang)的(de)(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)性能受粉塵(chen)(chen)性質(zhi)、設備構造(zao)和(he)煙(yan)氣流速等三(san)個(ge)因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)性的(de)(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)粒(li)難以保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)(shi)其重(zhong)返氣流。比電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷(he)(he)不易放(fang)(fang)出(chu)，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯度會產生局部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)現(xian)象(xiang)。這些情況都會造(zao)成(cheng)除塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)除(chu)塵(chen)器的基本原理是利用電(dian)(dian)(dian)力捕集(ji)煙(yan)氣中的粉(fen)(fen)塵(chen)，主要包括(kuo)以下(xia)四(si)個(ge)相互有(you)關的物(wu)理過程: (1) 氣體的電(dian)(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)的荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)向電(dian)(dian)(dian)極(ji)移(yi)動。(4) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)的捕集(ji)。
