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)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)收捕(bu)廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈化(hua)工(gong)作(zuo)(zuo)上要(yao)是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)(yun)極和(he)沉淀兩個系(xi)統(tong)(tong)來(lai)完(wan)成(cheng)的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)分布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)(zuo)用(yong)下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降低，其中(zhong)有(you)些較重的(de)(de)塵(chen)(chen)粒便失(shi)去速度而沉降下(xia)來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由于(yu)電(dian)(dian)(dian)(dian)暈(yun)(yun)極通(tong)人(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)極附近產生電(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)結合(he)起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)(zuo)用(yong)下(xia)趨向本(ben)設(she)備陽極(正極、本(ben)設(she)備采用(yong)負高(gao)壓(ya)制)和(he)陰極(負極) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)極上，通(tong)過(guo)設(she)備陰陽極振打(da)系(xi)統(tong)(tong)的(de)(de)振打(da)，使沉積(ji)在(zai)陰陽電(dian)(dian)(dian)(dian)極上的(de)(de)粉(fen)塵(chen)(chen)振落(luo)，進(jin)(jin)人(ren)集(ji)灰(hui)斗 通(tong)過(guo)排(pai)灰(hui)裝置放出，回收有(you)物料，被)凈化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)體排(pai)入(ru)大(da)氣(qi)(qi)(qi)(qi)。

工(gong)作(zuo)原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)工作(zuo)原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)使煙(yan)(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)作(zuo)用下與氣(qi)(qi)流分離(li)。負(fu)極(ji)(ji)由不同斷面形(xing)(xing)狀(zhuang)的(de)(de)(de)(de)金屬導線制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾(ji)何(he)形(xing)(xing)狀(zhuang)的(de)(de)(de)(de)金屬板制成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)性(xing)能受(shou)粉(fen)(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設(she)備構造和煙(yan)(yan)氣(qi)(qi)流速等三(san)個因素的(de)(de)(de)(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出(chu)，在(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生(sheng)局(ju)部擊(ji)穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除(chu)塵器(qi)的基(ji)本(ben)原理是利用電(dian)(dian)力(li)捕集(ji)煙(yan)氣中的粉(fen)塵，主要包括以下四個相互有關的物理過程: (1) 氣體(ti)的電(dian)(dian)離(li)。(2) 粉(fen)塵的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉(fen)塵的捕集(ji)。
