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。

臥式靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈化法來(lai)(lai)(lai)收捕廢氣(qi)中(zhong)(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈化工(gong)作(zuo)(zuo)上要是依靠(kao)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和沉淀兩個系(xi)統(tong)來(lai)(lai)(lai)完成的(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進人(ren)氣(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)分布板以及折(zhe)流(liu)板的(de)(de)(de)調整后，使氣(qi)流(liu)能較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面(mian)擴大(da)(da)(da)的(de)(de)(de)作(zuo)(zuo)用下，氣(qi)流(liu)速度(du)迅速降低(di)，其中(zhong)(zhong)有些較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失(shi)去速度(du)而沉降下來(lai)(lai)(lai)。進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)體(ti)(ti)(ti)中(zhong)(zhong)存在(zai)大(da)(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)(dian)子和離(li)子與進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)結合(he)起來(lai)(lai)(lai)，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)(zuo)用下趨(qu)向本(ben)設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備采(cai)用負(fu)高壓(ya)制)和陰(yin)(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子分別(bie)沉積在(zai)相(xiang)應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設備陰(yin)(yin)陽(yang)極(ji)(ji)(ji)振打系(xi)統(tong)的(de)(de)(de)振打，使沉積在(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)振落(luo)，進人(ren)集灰斗 通過排(pai)灰裝置放出，回收有物料，被(bei))凈化的(de)(de)(de)氣(qi)體(ti)(ti)(ti)排(pai)入大(da)(da)(da)氣(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣流中的粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣流分離(li)。負極(ji)(ji)由(you)(you)不(bu)同斷面(mian)形(xing)狀的金(jin)(jin)屬導(dao)線制(zhi)成，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)(you)不(bu)同幾何形(xing)狀的金(jin)(jin)屬板制(zhi)成，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設(she)備構(gou)造和煙氣流速(su)等(deng)三個因素(su)的影(ying)響。粉塵(chen)(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評(ping)價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的指標，它對除(chu)塵(chen)(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接的影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵(chen)器的(de)基本原(yuan)理是利用電(dian)力捕集煙氣中(zhong)的(de)粉(fen)塵(chen)，主要(yao)包括以下(xia)四個相(xiang)互有關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵(chen)的(de)捕集。
