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)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈(jing)化工作(zuo)上要是依(yi)靠電(dian)(dian)(dian)暈極(ji)和(he)沉(chen)淀(dian)兩個系統來(lai)完(wan)成的(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)刺(ci)叭(ba)時，含(han)塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板(ban)以及(ji)折流(liu)(liu)板(ban)的(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)(liu)能較(jiao)均(jun)勻(yun)地進人電(dian)(dian)(dian)場。在橫斷面擴大(da)(da)的(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速度(du)迅速降低，其(qi)中(zhong)有(you)些(xie)較(jiao)重(zhong)的(de)(de)塵(chen)粒(li)(li)便失(shi)去速度(du)而沉(chen)降下(xia)來(lai)。進人電(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)暈極(ji)通人高壓(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存在大(da)(da)量的(de)(de)電(dian)(dian)(dian)子和(he)離子，這些(xie)電(dian)(dian)(dian)子和(he)離子與進人電(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)結合起來(lai)，使塵(chen)粒(li)(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)(li)在電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下(xia)趨向本設(she)備(bei)陽極(ji)(正極(ji)、本設(she)備(bei)采用負高壓(ya)制)和(he)陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉(chen)積在相應的(de)(de)電(dian)(dian)(dian)極(ji)上，通過(guo)設(she)備(bei)陰陽極(ji)振打系統的(de)(de)振打，使沉(chen)積在陰陽電(dian)(dian)(dian)極(ji)上的(de)(de)粉(fen)塵(chen)振落(luo)，進人集(ji)灰斗 通過(guo)排灰裝置放(fang)出，回收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工作原理是(shi)利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙(yan)(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)流(liu)分離(li)。負(fu)極(ji)由不同(tong)斷面形(xing)(xing)狀(zhuang)的(de)(de)(de)金(jin)屬(shu)導(dao)線制成，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形(xing)(xing)狀(zhuang)的(de)(de)(de)金(jin)屬(shu)板制成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質(zhi)、設備構造和(he)煙(yan)(yan)氣(qi)流(liu)速等三個因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)效率有直接的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難(nan)以保(bao)持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，致(zhi)使(shi)其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不易(yi)放出，在塵(chen)(chen)(chen)層(ceng)之間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿(chuan)和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會(hui)造成除塵(chen)(chen)(chen)效率下降。

電(dian)除塵器的(de)(de)(de)基(ji)本(ben)原理是利用(yong)電(dian)力捕集煙氣中的(de)(de)(de)粉塵，主要包括以下四個相(xiang)互有關的(de)(de)(de)物(wu)理過程: (1) 氣體(ti)的(de)(de)(de)電(dian)離。(2) 粉塵的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移動(dong)。(4) 荷電(dian)粉塵的(de)(de)(de)捕集。
