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)靜電(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈化(hua)法來收捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈化(hua)工作(zuo)(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和(he)(he)沉(chen)淀兩個系(xi)統來完成的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)(jin)人(ren)氣(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)(liu)分(fen)布板(ban)(ban)以(yi)及折流(liu)(liu)板(ban)(ban)的(de)(de)調整后(hou)，使氣(qi)(qi)流(liu)(liu)能(neng)較均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場。在橫斷面擴(kuo)大(da)的(de)(de)作(zuo)(zuo)用(yong)(yong)下(xia)，氣(qi)(qi)流(liu)(liu)速(su)度迅速(su)降低，其中(zhong)有些較重的(de)(de)塵(chen)(chen)粒(li)便失(shi)去速(su)度而沉(chen)降下(xia)來。進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通人(ren)高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)體(ti)中(zhong)存在大(da)量的(de)(de)電(dian)(dian)(dian)子和(he)(he)離子，這(zhe)些電(dian)(dian)(dian)子和(he)(he)離子與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)(chen)結(jie)合起(qi)來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)場力的(de)(de)作(zuo)(zuo)用(yong)(yong)下(xia)趨向本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備(bei)采用(yong)(yong)負高壓制(zhi))和(he)(he)陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分(fen)別沉(chen)積在相(xiang)應(ying)的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)，通過設(she)備(bei)陰陽(yang)極(ji)(ji)(ji)(ji)振打(da)系(xi)統的(de)(de)振打(da)，使沉(chen)積在陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)的(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝(zhuang)置(zhi)放出，回收有物料，被)凈化(hua)的(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除塵(chen)器的工作原(yuan)理是利(li)用(yong)高壓電(dian)(dian)(dian)場(chang)使煙氣發(fa)生(sheng)電(dian)(dian)(dian)離，氣流中的粉塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用(yong)下與氣流分離。負(fu)極(ji)(ji)(ji)由不同斷面(mian)形(xing)(xing)狀的金(jin)屬(shu)導線制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同幾何形(xing)(xing)狀的金(jin)屬(shu)板(ban)制(zhi)成(cheng)，叫(jiao)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)除塵(chen)器的性(xing)能受粉塵(chen)性(xing)質(zhi)、設備構造和煙氣流速等三個(ge)因素的影響。粉塵(chen)的比(bi)電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性(xing)的指標，它(ta)對除塵(chen)效率(lv)有直接(jie)的影響。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保持在集塵(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，致使其重返氣流。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)的塵(chen)粒(li)電(dian)(dian)(dian)荷不易放(fang)出(chu)，在塵(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)(dian)現象(xiang)。這些情況(kuang)都會造成(cheng)除塵(chen)效率(lv)下降。

電(dian)除(chu)塵(chen)(chen)器(qi)的(de)基本原理(li)是利(li)用(yong)電(dian)力捕集(ji)煙氣中(zhong)的(de)粉(fen)(fen)塵(chen)(chen)，主要包(bao)括以(yi)下四個相互(hu)有(you)關的(de)物理(li)過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕集(ji)。
