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)除塵器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵，它的(de)(de)(de)(de)凈化工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系統來完成的(de)(de)(de)(de)，當含塵氣(qi)體(ti)(ti)進(jin)(jin)人氣(qi)刺(ci)叭時，含塵氣(qi)體(ti)(ti)受(shou)到氣(qi)流(liu)分布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)能較(jiao)均(jun)勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷(duan)面擴(kuo)大(da)的(de)(de)(de)(de)作(zuo)用下，氣(qi)流(liu)速(su)度(du)迅速(su)降低(di)，其中(zhong)有些(xie)較(jiao)重的(de)(de)(de)(de)塵粒便(bian)失(shi)去速(su)度(du)而沉降下來。進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵氣(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人高(gao)壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵結合起來，使(shi)塵粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下趨向本設(she)備(bei)陽極(ji)(正極(ji)、本設(she)備(bei)采用負高(gao)壓(ya)制)和(he)陰(yin)極(ji)(負極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子分別沉積在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設(she)備(bei)陰(yin)陽極(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)振(zhen)(zhen)打，使(shi)沉積在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)塵振(zhen)(zhen)落，進(jin)(jin)人集灰斗 通(tong)過排灰裝置放出，回收有物料，被(bei))凈化的(de)(de)(de)(de)氣(qi)體(ti)(ti)排入(ru)大(da)氣(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作原理是(shi)利(li)用高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣發(fa)生電(dian)(dian)(dian)(dian)離，氣流中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下與(yu)氣流分離。負極由不(bu)(bu)同(tong)斷面形(xing)狀(zhuang)的(de)金(jin)屬導(dao)(dao)線(xian)制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正(zheng)極由不(bu)(bu)同(tong)幾何形(xing)狀(zhuang)的(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性能受粉塵(chen)(chen)(chen)性質(zhi)、設備構造(zao)和煙氣流速(su)等(deng)三個因素(su)的(de)影響(xiang)(xiang)。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是(shi)評價導(dao)(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)效率(lv)(lv)有直接的(de)影響(xiang)(xiang)。比電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒(li)(li)難(nan)以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致(zhi)使其重返氣流。比電(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒(li)(li)電(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)效率(lv)(lv)下降。

電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)基(ji)本原理是利用電(dian)(dian)(dian)力捕集煙氣(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，主要包括以下四(si)個(ge)相互有關的(de)(de)(de)物理過程: (1) 氣(qi)體(ti)的(de)(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)捕集。
