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)除塵(chen)(chen)(chen)器(qi)是以(yi)(yi)靜電(dian)凈(jing)(jing)化法(fa)來收(shou)捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)(jing)化工作上要是依靠(kao)電(dian)暈極(ji)(ji)(ji)(ji)和沉淀兩個系(xi)統來完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體進人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)分布(bu)板(ban)以(yi)(yi)及(ji)折(zhe)流(liu)(liu)(liu)板(ban)的(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)能(neng)較均勻地進人(ren)(ren)電(dian)場(chang)。在橫斷面擴(kuo)大(da)的(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度(du)迅速(su)降低，其中(zhong)有(you)些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去速(su)度(du)而沉降下來。進人(ren)(ren)電(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)暈極(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高(gao)壓直(zhi)流(liu)(liu)(liu)電(dian)，則(ze)在電(dian)暈極(ji)(ji)(ji)(ji)附近產生電(dian)暈現象，使氣(qi)(qi)(qi)(qi)體電(dian)離(li)(li)，電(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在大(da)量的(de)(de)(de)(de)電(dian)子(zi)和離(li)(li)子(zi)，這些電(dian)子(zi)和離(li)(li)子(zi)與進人(ren)(ren)電(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)粒帶電(dian)，帶電(dian)塵(chen)(chen)(chen)粒在電(dian)場(chang)力的(de)(de)(de)(de)作用(yong)下趨向本設(she)備(bei)(bei)陽(yang)(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備(bei)(bei)采用(yong)負高(gao)壓制(zhi))和陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)子(zi)分別沉積在相(xiang)應的(de)(de)(de)(de)電(dian)極(ji)(ji)(ji)(ji)上，通(tong)過(guo)設(she)備(bei)(bei)陰陽(yang)(yang)極(ji)(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)振(zhen)打，使沉積在陰陽(yang)(yang)電(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落，進人(ren)(ren)集灰(hui)斗 通(tong)過(guo)排(pai)(pai)灰(hui)裝置放出，回收(shou)有(you)物(wu)料，被(bei))凈(jing)(jing)化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體排(pai)(pai)入(ru)大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)工作(zuo)原理是(shi)(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)流分離。負極(ji)由不同斷(duan)面形狀(zhuang)的(de)(de)金屬(shu)導(dao)線制成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾(ji)何形狀(zhuang)的(de)(de)金屬(shu)板(ban)制成，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設備構造和(he)煙(yan)氣(qi)流速等(deng)三個(ge)因素的(de)(de)影響。粉(fen)塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)(shi)評(ping)價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標(biao)，它對除(chu)(chu)塵(chen)效(xiao)率(lv)有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)低，塵(chen)粒(li)難以(yi)保持在(zai)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)高，到達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出(chu)，在(zai)塵(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況(kuang)都會造成除(chu)(chu)塵(chen)效(xiao)率(lv)下(xia)降。

電(dian)除塵(chen)器的(de)基本原理是利用電(dian)力捕集煙(yan)氣中(zhong)的(de)粉塵(chen)，主要(yao)包(bao)括以下四個相互有關的(de)物理過程: (1) 氣體(ti)(ti)的(de)電(dian)離(li)。(2) 粉塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)向電(dian)極(ji)移動。(4) 荷(he)電(dian)粉塵(chen)的(de)捕集。
