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)除塵器是以(yi)靜電(dian)(dian)(dian)(dian)凈化法來(lai)收(shou)捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉塵，它的(de)(de)(de)凈化工(gong)作(zuo)上要是依靠電(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)(chen)淀兩個(ge)系統來(lai)完成(cheng)的(de)(de)(de)，當含(han)塵氣(qi)(qi)體進(jin)人(ren)氣(qi)(qi)刺叭時，含(han)塵氣(qi)(qi)體受到氣(qi)(qi)流(liu)(liu)分(fen)布板以(yi)及折流(liu)(liu)板的(de)(de)(de)調整后(hou)(hou)，使(shi)氣(qi)(qi)流(liu)(liu)能較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴(kuo)大(da)的(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)流(liu)(liu)速度迅速降(jiang)低，其中(zhong)有(you)些(xie)較(jiao)重(zhong)的(de)(de)(de)塵粒便失去速度而(er)沉(chen)(chen)降(jiang)下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)(hou)的(de)(de)(de)氣(qi)(qi)體中(zhong)存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵結合(he)起來(lai)，使(shi)塵粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵粒在電(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作(zuo)用下(xia)趨向(xiang)本設(she)備(bei)陽(yang)極(ji)(正極(ji)、本設(she)備(bei)采用負高壓制)和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積在相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過設(she)備(bei)陰(yin)陽(yang)極(ji)振(zhen)(zhen)打(da)系統的(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)沉(chen)(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵振(zhen)(zhen)落，進(jin)人(ren)集灰斗 通過排灰裝置放出，回收(shou)有(you)物料，被)凈化的(de)(de)(de)氣(qi)(qi)體排入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作原理是利(li)用高壓電(dian)(dian)場(chang)使(shi)煙氣發(fa)生電(dian)(dian)離，氣流(liu)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣流(liu)分離。負極(ji)(ji)由不同(tong)斷面(mian)形狀的(de)(de)(de)金屬導(dao)線(xian)制成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何(he)形狀的(de)(de)(de)金屬板制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)(chen)性質、設(she)備構造和煙氣流(liu)速等三(san)個因素的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)阻是評價導(dao)電(dian)(dian)性的(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣流(liu)。比(bi)電(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)現象。這些情況都會造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率下降。

電除(chu)塵(chen)(chen)器(qi)的(de)(de)基本原理是利用電力(li)捕集煙氣中的(de)(de)粉塵(chen)(chen)，主要包括以下四個相(xiang)互有(you)關的(de)(de)物理過(guo)程(cheng): (1) 氣體(ti)的(de)(de)電離。(2) 粉塵(chen)(chen)的(de)(de)荷電。(3) 荷電粉塵(chen)(chen)向電極移動。(4) 荷電粉塵(chen)(chen)的(de)(de)捕集。
