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(jing)電除(chu)塵(chen)(chen)(chen)(chen)(chen)器是(shi)以(yi)(yi)靜(jing)電凈化法來收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它(ta)的(de)(de)(de)(de)(de)凈化工作上(shang)要是(shi)依靠電暈極(ji)(ji)和(he)沉淀兩個系統來完成的(de)(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體進人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流(liu)(liu)分(fen)布板(ban)以(yi)(yi)及折流(liu)(liu)板(ban)的(de)(de)(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較(jiao)均勻(yun)地進人(ren)電場。在(zai)橫斷面擴(kuo)大(da)(da)的(de)(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)流(liu)(liu)速度(du)迅(xun)速降(jiang)低(di)，其中有(you)些較(jiao)重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)便失去速度(du)而(er)沉降(jiang)下來。進人(ren)電場的(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體由于電暈極(ji)(ji)通人(ren)高壓(ya)直流(liu)(liu)電，則(ze)在(zai)電暈極(ji)(ji)附近產(chan)生電暈現(xian)象，使(shi)氣(qi)(qi)(qi)體電離(li)，電離(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體中存在(zai)大(da)(da)量的(de)(de)(de)(de)(de)電子(zi)和(he)離(li)子(zi)，這(zhe)些電子(zi)和(he)離(li)子(zi)與進人(ren)電場的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)(chen)(chen)粒(li)帶電，帶電塵(chen)(chen)(chen)(chen)(chen)粒(li)在(zai)電場力的(de)(de)(de)(de)(de)作用下趨向(xiang)本設(she)(she)(she)備(bei)陽(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)(she)(she)備(bei)采用負高壓(ya)制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電子(zi)分(fen)別沉積(ji)(ji)在(zai)相應的(de)(de)(de)(de)(de)電極(ji)(ji)上(shang)，通過設(she)(she)(she)備(bei)陰陽(yang)極(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)(de)(de)振(zhen)打(da)，使(shi)沉積(ji)(ji)在(zai)陰陽(yang)電極(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)集灰(hui)(hui)斗 通過排灰(hui)(hui)裝(zhuang)置放出，回收(shou)有(you)物(wu)料，被)凈化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體排入大(da)(da)氣(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與氣流(liu)分離(li)。負極(ji)(ji)由不(bu)同斷面形狀的(de)(de)金屬導(dao)(dao)線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何形狀的(de)(de)金屬板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)性質、設(she)備構造(zao)和(he)煙氣流(liu)速(su)等三(san)個(ge)因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致(zhi)使其重(zhong)返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出(chu)，在塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)效率下(xia)降。

電除塵(chen)器的(de)(de)(de)基本原理是利用(yong)電力(li)捕集煙氣中的(de)(de)(de)粉(fen)塵(chen)，主要包括以下四個相互(hu)有關(guan)的(de)(de)(de)物理過(guo)程: (1) 氣體的(de)(de)(de)電離。(2) 粉(fen)塵(chen)的(de)(de)(de)荷電。(3) 荷電粉(fen)塵(chen)向電極移動(dong)。(4) 荷電粉(fen)塵(chen)的(de)(de)(de)捕集。
