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)(dian)(dian)除塵(chen)器(qi)是以(yi)(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)(lai)收捕廢氣(qi)中(zhong)的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈化工作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)(chen)淀(dian)兩個系統來(lai)(lai)完成的(de)(de)，當(dang)含塵(chen)氣(qi)體進(jin)(jin)人氣(qi)刺叭(ba)時，含塵(chen)氣(qi)體受到氣(qi)流分布板以(yi)(yi)及(ji)折流板的(de)(de)調整(zheng)后，使氣(qi)流能較(jiao)均勻地(di)進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴大(da)的(de)(de)作用下，氣(qi)流速(su)度迅(xun)速(su)降低，其中(zhong)有(you)些(xie)較(jiao)重的(de)(de)塵(chen)粒便(bian)失去速(su)度而沉(chen)(chen)降下來(lai)(lai)。進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)氣(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附(fu)近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)氣(qi)體中(zhong)存在大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子與(yu)進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)結合起來(lai)(lai)，使塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用下趨向本(ben)(ben)設(she)備(bei)陽極(ji)(ji)(正極(ji)(ji)、本(ben)(ben)設(she)備(bei)采(cai)用負(fu)高壓(ya)制)和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別(bie)沉(chen)(chen)積(ji)在相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設(she)備(bei)陰陽極(ji)(ji)振(zhen)打系統的(de)(de)振(zhen)打，使沉(chen)(chen)積(ji)在陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)(jin)人集(ji)灰(hui)斗 通過排灰(hui)裝置放出，回收有(you)物(wu)料，被)凈化的(de)(de)氣(qi)體排入大(da)氣(qi)。

工作(zuo)原(yuan)理

靜(jing)電(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原理是利用(yong)高(gao)壓(ya)電(dian)場使(shi)煙(yan)氣(qi)發生電(dian)離，氣(qi)流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)在電(dian)場作(zuo)用(yong)下與氣(qi)流(liu)分離。負極(ji)由不同(tong)斷面形(xing)狀的(de)(de)金屬導線制成(cheng)，叫放(fang)電(dian)電(dian)極(ji)。正極(ji)由不同(tong)幾何(he)形(xing)狀的(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)極(ji)。靜(jing)電(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造和(he)煙(yan)氣(qi)流(liu)速等(deng)三個(ge)因素(su)的(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)阻(zu)是評價導電(dian)性的(de)(de)指(zhi)標(biao)，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接(jie)的(de)(de)影響(xiang)。比(bi)電(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)(chen)(chen)電(dian)極(ji)上，致使(shi)其重返氣(qi)流(liu)。比(bi)電(dian)阻(zu)過(guo)高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)壓(ya)梯(ti)度(du)會產生局(ju)部(bu)擊穿和(he)放(fang)電(dian)現象。這(zhe)些情況(kuang)都會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)除塵器的基本(ben)原(yuan)理是利用電(dian)(dian)力(li)捕集(ji)煙(yan)氣中(zhong)的粉塵，主要包括以(yi)下四個(ge)相互(hu)有關的物理過程: (1) 氣體的電(dian)(dian)離。(2) 粉塵的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的捕集(ji)。
