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(shi)靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)法(fa)來收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀兩個系統(tong)來完成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場。在橫(heng)斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降(jiang)低，其中有(you)些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒便失(shi)去(qu)速度而沉降(jiang)下來。進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)(tong)人(ren)(ren)(ren)高(gao)壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)作(zuo)用(yong)下趨向本設(she)備陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采用(yong)負(fu)高(gao)壓(ya)制)和(he)陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)(fang)出電(dian)(dian)(dian)(dian)子(zi)分別沉積在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通(tong)(tong)過設(she)備陰(yin)陽(yang)(yang)極(ji)(ji)振(zhen)打(da)系統(tong)的(de)(de)(de)(de)振(zhen)打(da)，使沉積在陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)落(luo)，進(jin)(jin)人(ren)(ren)(ren)集灰斗 通(tong)(tong)過排灰裝置(zhi)放(fang)(fang)出，回收(shou)有(you)物料(liao)，被)凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工作原理(li)是利用(yong)高壓電(dian)(dian)(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)(dian)(dian)離，氣流中的(de)(de)(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用(yong)下與氣流分離。負極(ji)由不同斷(duan)面形(xing)(xing)狀(zhuang)的(de)(de)(de)金屬導(dao)(dao)線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同幾(ji)何形(xing)(xing)狀(zhuang)的(de)(de)(de)金屬板制(zhi)成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構造(zao)和煙氣流速等三個(ge)因(yin)素的(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)阻是評價(jia)導(dao)(dao)電(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它(ta)對除塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)(li)難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣流。比電(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒(li)(li)電(dian)(dian)(dian)(dian)荷(he)不易(yi)放出，在(zai)塵(chen)(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成除塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)除塵(chen)器(qi)的(de)基(ji)本原理是利用電(dian)(dian)力捕集(ji)煙氣中(zhong)的(de)粉塵(chen)，主要包括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)粉塵(chen)的(de)捕集(ji)。
