XWD型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)靜電(dian)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)(de)凈化(hua)(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)能較均勻地(di)進人電(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴大(da)的(de)(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流(liu)速度迅速降低(di)，其中有些(xie)較重(zhong)的(de)(de)(de)(de)(de)塵(chen)粒便失去速度而沉(chen)(chen)降下來(lai)。進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通人高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在大(da)量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)粉塵(chen)結合起來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)(de)(de)作(zuo)用下趨(qu)向本設(she)(she)(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)(she)(she)備采(cai)用負高(gao)壓(ya)制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積(ji)在相應(ying)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設(she)(she)(she)備陰(yin)陽(yang)極(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)(de)振(zhen)打，使沉(chen)(chen)積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉塵(chen)振(zhen)落(luo)，進人集灰斗 通過排灰裝置放出(chu)，回(hui)收有物料，被)凈化(hua)(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)工作原(yuan)理(li)是(shi)利用高壓電(dian)(dian)(dian)(dian)場(chang)(chang)使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)作用下(xia)與(yu)氣(qi)流(liu)分離(li)。負極(ji)由不同(tong)斷(duan)面(mian)形狀的(de)(de)(de)金(jin)屬(shu)導(dao)線制成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形狀的(de)(de)(de)金(jin)屬(shu)板制成，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)性能受(shou)粉(fen)塵(chen)性質、設備構(gou)造和煙(yan)氣(qi)流(liu)速等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導(dao)電(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)效率有(you)直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保持在(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出，在(zai)塵(chen)層之間(jian)形成電(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些情況(kuang)都(dou)會(hui)造成除(chu)塵(chen)效率下(xia)降。

電(dian)(dian)除塵器的(de)(de)基本原理是利用電(dian)(dian)力捕集(ji)煙氣中的(de)(de)粉塵，主要包括以下四個相互有(you)關的(de)(de)物理過程: (1) 氣體(ti)的(de)(de)電(dian)(dian)離(li)。(2) 粉塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉塵的(de)(de)捕集(ji)。
