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)式靜電(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)凈(jing)化法來(lai)收捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化工作(zuo)上(shang)(shang)(shang)要是依(yi)靠電(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)(he)沉淀兩個系統來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)能較(jiao)均勻地(di)進(jin)人電(dian)(dian)場(chang)。在橫斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)速度迅速降低，其中(zhong)有(you)些較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去(qu)速度而(er)沉降下(xia)來(lai)。進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高壓直(zhi)流(liu)電(dian)(dian)，則(ze)在電(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在大量(liang)的(de)(de)(de)(de)電(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)，這些電(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)與(yu)進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)作(zuo)用(yong)下(xia)趨向本設備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采用(yong)負高壓制)和(he)(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放出(chu)電(dian)(dian)子(zi)(zi)分別沉積(ji)在相(xiang)應(ying)的(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)(shang)，通過(guo)設備(bei)陰陽(yang)極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)振打(da)，使(shi)(shi)沉積(ji)在陰陽(yang)電(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)(shang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振落，進(jin)人集灰斗 通過(guo)排灰裝置放出(chu)，回收有(you)物料，被)凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)工作(zuo)原理是利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)(li)，氣(qi)流中(zhong)的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分離(li)(li)。負極(ji)(ji)由(you)不同(tong)斷面形狀的(de)(de)金屬(shu)導(dao)線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同(tong)幾(ji)何形狀的(de)(de)金屬(shu)板(ban)制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)性能(neng)受(shou)粉塵(chen)(chen)(chen)(chen)(chen)性質、設備構造和煙氣(qi)流速(su)等三個(ge)因(yin)素的(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有(you)直接(jie)的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不易(yi)放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)產生局部(bu)擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器的(de)(de)基本(ben)原理(li)(li)是(shi)利(li)用電(dian)(dian)力捕(bu)集煙氣中的(de)(de)粉塵(chen)，主要(yao)包括(kuo)以下四個相互有關的(de)(de)物理(li)(li)過程: (1) 氣體的(de)(de)電(dian)(dian)離(li)。(2) 粉塵(chen)的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)極移(yi)動。(4) 荷(he)電(dian)(dian)粉塵(chen)的(de)(de)捕(bu)集。
