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)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)(de)凈(jing)化工作(zuo)上(shang)要是依(yi)靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和沉淀兩個系(xi)統來(lai)完成的(de)(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分布板(ban)以及(ji)折流(liu)板(ban)的(de)(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)(qi)流(liu)能較均勻(yun)地(di)進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降(jiang)低，其(qi)中有(you)些較重的(de)(de)(de)(de)(de)塵(chen)粒便失去速度(du)而沉降(jiang)下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)(tong)人(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中存在(zai)(zai)大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)結合起來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下趨向本設備(bei)(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)(bei)采用(yong)(yong)負高壓制)和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)(tong)過設備(bei)(bei)陰陽(yang)極(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)(de)振(zhen)打，使沉積在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)落(luo)，進人(ren)(ren)集灰斗 通(tong)(tong)過排灰裝置放出，回收有(you)物料(liao)，被)凈(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作原理(li)是利(li)用(yong)(yong)高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)場(chang)(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)作用(yong)(yong)下與氣(qi)流(liu)(liu)分(fen)離。負(fu)極(ji)(ji)由(you)不(bu)(bu)同斷面(mian)形(xing)狀的(de)(de)金(jin)屬導線制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)不(bu)(bu)同幾何形(xing)狀的(de)(de)金(jin)屬板制成，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)性質、設備(bei)構造(zao)和(he)煙(yan)氣(qi)流(liu)(liu)速等三個因素的(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒(li)難以(yi)保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使其重(zhong)返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會產生局(ju)部擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這(zhe)些情況都(dou)會造(zao)成除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除(chu)塵(chen)器的(de)基本原理(li)是利(li)用電(dian)(dian)力(li)捕集(ji)煙(yan)氣中(zhong)的(de)粉(fen)塵(chen)，主(zhu)要包(bao)括以下四個相互有關的(de)物理(li)過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)的(de)捕集(ji)。
