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(wo)式(shi)靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣中的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈化(hua)工作上(shang)(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉(chen)淀(dian)兩個系統來(lai)完成的(de)(de)(de)，當含(han)塵(chen)氣體(ti)進(jin)(jin)(jin)人(ren)(ren)氣刺叭(ba)時，含(han)塵(chen)氣體(ti)受(shou)到氣流分布板以及折流板的(de)(de)(de)調整后(hou)，使氣流能較均勻地進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴大(da)(da)的(de)(de)(de)作用(yong)下，氣流速度(du)迅速降低，其中有(you)些較重(zhong)的(de)(de)(de)塵(chen)粒(li)便失去(qu)速度(du)而沉(chen)降下來(lai)。進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)氣體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)(tong)人(ren)(ren)高壓(ya)(ya)直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象，使氣體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣體(ti)中存在大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)結合(he)起來(lai)，使塵(chen)粒(li)帶(dai)(dai)電(dian)(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)(dian)塵(chen)粒(li)在電(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作用(yong)下趨向本(ben)設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備采用(yong)負(fu)高壓(ya)(ya)制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)，通(tong)(tong)過設備陰(yin)陽(yang)極(ji)(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)振(zhen)打(da)，使沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)的(de)(de)(de)粉(fen)塵(chen)振(zhen)落(luo)，進(jin)(jin)(jin)人(ren)(ren)集灰斗 通(tong)(tong)過排灰裝置(zhi)放出，回收有(you)物料，被)凈化(hua)的(de)(de)(de)氣體(ti)排入大(da)(da)氣。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)工作原理是利用(yong)高(gao)壓電(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)離(li)(li)，氣(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用(yong)下與氣(qi)流(liu)分離(li)(li)。負極(ji)由不(bu)同(tong)斷面形(xing)狀的(de)金屬導(dao)線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾(ji)何形(xing)狀的(de)金屬板(ban)制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)流(liu)速等三個因素的(de)影響(xiang)。粉(fen)塵(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻是評價(jia)導(dao)電(dian)(dian)(dian)性(xing)的(de)指(zhi)標，它對除(chu)塵(chen)(chen)效率有直接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)現象(xiang)。這些情況都會(hui)造成(cheng)除(chu)塵(chen)(chen)效率下降。

電除塵(chen)器(qi)的基(ji)本原理是利用電力(li)捕集煙氣(qi)中的粉(fen)塵(chen)，主(zhu)要包括以下四(si)個相互有關的物理過程: (1) 氣(qi)體的電離(li)。(2) 粉(fen)塵(chen)的荷電。(3) 荷電粉(fen)塵(chen)向(xiang)電極移動。(4) 荷電粉(fen)塵(chen)的捕集。
