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(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)是(shi)(shi)以(yi)靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)法(fa)來(lai)(lai)收捕(bu)廢氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作(zuo)上要是(shi)(shi)依靠電(dian)(dian)(dian)暈極(ji)和沉淀兩(liang)個系(xi)統(tong)來(lai)(lai)完(wan)成的(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布板以(yi)及折流板的(de)(de)調整(zheng)后(hou)，使(shi)(shi)氣(qi)(qi)流能較均勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面(mian)擴大(da)的(de)(de)作(zuo)用下，氣(qi)(qi)流速度(du)迅速降低，其(qi)中有些較重的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速度(du)而沉降下來(lai)(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)通人(ren)(ren)(ren)高壓(ya)直流電(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)暈現(xian)象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)子和離(li)子與(yu)進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結(jie)合起來(lai)(lai)，使(shi)(shi)塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下趨向本設(she)(she)備陽極(ji)(正極(ji)、本設(she)(she)備采(cai)用負(fu)高壓(ya)制)和陰(yin)極(ji)(負(fu)極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子分別沉積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)上，通過(guo)設(she)(she)備陰(yin)陽極(ji)振打(da)系(xi)統(tong)的(de)(de)振打(da)，使(shi)(shi)沉積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落，進(jin)人(ren)(ren)(ren)集灰斗 通過(guo)排灰裝置放出(chu)，回收有物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工(gong)作原理(li)

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作原(yuan)理是(shi)利(li)用(yong)(yong)高壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用(yong)(yong)下(xia)與氣(qi)流(liu)分離。負(fu)極由不同斷面形狀的(de)(de)金屬導線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不同幾(ji)何(he)形狀的(de)(de)金屬板(ban)制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)(xing)能受(shou)粉塵(chen)(chen)(chen)(chen)(chen)性(xing)(xing)質、設備(bei)構造和煙氣(qi)流(liu)速(su)等三個因素的(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性(xing)(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)(chen)效率(lv)(lv)有直接的(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯度(du)會產生局部(bu)擊(ji)穿和放(fang)電(dian)(dian)(dian)現象(xiang)。這些情況(kuang)都(dou)會造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)(chen)效率(lv)(lv)下(xia)降。

電除塵(chen)器(qi)的(de)基本(ben)原(yuan)理是利用電力捕(bu)集煙氣中的(de)粉(fen)塵(chen)，主要包括以(yi)下四個相(xiang)互有關的(de)物(wu)理過程: (1) 氣體(ti)的(de)電離。(2) 粉(fen)塵(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)向電極(ji)移(yi)動(dong)。(4) 荷(he)電粉(fen)塵(chen)的(de)捕(bu)集。
