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(wo)式靜(jing)電(dian)除塵(chen)(chen)器是以靜(jing)電(dian)凈(jing)化(hua)法(fa)來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的粉(fen)塵(chen)(chen)，它的凈(jing)化(hua)工作(zuo)上要是依靠(kao)電(dian)暈(yun)極(ji)和沉(chen)(chen)(chen)淀兩個(ge)系統來(lai)完(wan)成(cheng)的，當含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流分(fen)布(bu)板(ban)以及折流板(ban)的調(diao)整(zheng)后，使(shi)氣(qi)(qi)(qi)流能較均勻(yun)地(di)進人(ren)電(dian)場(chang)。在橫斷面擴大的作(zuo)用下(xia)，氣(qi)(qi)(qi)流速度迅(xun)速降低，其中(zhong)有(you)(you)些較重的塵(chen)(chen)粒(li)(li)便(bian)失去(qu)速度而沉(chen)(chen)(chen)降下(xia)來(lai)。進人(ren)電(dian)場(chang)的含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)暈(yun)極(ji)通(tong)人(ren)高壓(ya)直流電(dian)，則(ze)在電(dian)暈(yun)極(ji)附近(jin)產生電(dian)暈(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)離(li)，電(dian)離(li)后的氣(qi)(qi)(qi)體(ti)中(zhong)存在大量(liang)的電(dian)子(zi)(zi)和離(li)子(zi)(zi)，這(zhe)些電(dian)子(zi)(zi)和離(li)子(zi)(zi)與進人(ren)電(dian)場(chang)的粉(fen)塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒(li)(li)帶(dai)電(dian)，帶(dai)電(dian)塵(chen)(chen)粒(li)(li)在電(dian)場(chang)力的作(zuo)用下(xia)趨向本設備陽極(ji)(正極(ji)、本設備采用負高壓(ya)制)和陰(yin)極(ji)(負極(ji)) ， 釋放(fang)出電(dian)子(zi)(zi)分(fen)別沉(chen)(chen)(chen)積(ji)在相(xiang)應的電(dian)極(ji)上，通(tong)過設備陰(yin)陽極(ji)振打(da)系統的振打(da)，使(shi)沉(chen)(chen)(chen)積(ji)在陰(yin)陽電(dian)極(ji)上的粉(fen)塵(chen)(chen)振落，進人(ren)集灰斗 通(tong)過排灰裝置放(fang)出，回收有(you)(you)物料(liao)，被(bei))凈(jing)化(hua)的氣(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)工(gong)作(zuo)原理(li)是利(li)用(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)離，氣(qi)(qi)(qi)流(liu)(liu)(liu)中的(de)粉(fen)(fen)(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作(zuo)用(yong)下與氣(qi)(qi)(qi)流(liu)(liu)(liu)分(fen)離。負極(ji)由(you)不(bu)同斷面(mian)形狀(zhuang)(zhuang)的(de)金屬導(dao)(dao)線制成，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同幾何形狀(zhuang)(zhuang)的(de)金屬板制成，叫集塵(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)性能受粉(fen)(fen)(fen)塵(chen)性質(zhi)、設備(bei)構造和煙氣(qi)(qi)(qi)流(liu)(liu)(liu)速等三個因素(su)的(de)影(ying)響。粉(fen)(fen)(fen)塵(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它對(dui)除(chu)塵(chen)效率有直接的(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保持在(zai)集塵(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)(qi)流(liu)(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出，在(zai)塵(chen)層之間(jian)形成電(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造成除(chu)塵(chen)效率下降。

電(dian)(dian)除塵(chen)器的(de)基本原理是利用(yong)電(dian)(dian)力捕集煙(yan)氣中的(de)粉(fen)塵(chen)，主要包括以(yi)下四個相(xiang)互有關的(de)物理過程: (1) 氣體(ti)的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)的(de)捕集。
