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)(dian)除塵(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢(fei)氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈化工(gong)作(zuo)上(shang)要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)(ren)氣(qi)(qi)刺(ci)叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)(de)(de)調整后(hou)，使(shi)(shi)(shi)氣(qi)(qi)流(liu)能較均勻地(di)進人(ren)(ren)電(dian)(dian)(dian)(dian)場。在橫(heng)斷面擴大的(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)速度迅速降低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)粒便失去速度而沉(chen)降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在大量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)結(jie)合起來(lai)，使(shi)(shi)(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用(yong)下趨向本設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用(yong)負高壓制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放(fang)出(chu)電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備(bei)陰(yin)陽(yang)極(ji)(ji)振打(da)系(xi)統的(de)(de)(de)振打(da)，使(shi)(shi)(shi)沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)振落，進人(ren)(ren)集灰斗 通過排灰裝置放(fang)出(chu)，回收有物料(liao)，被(bei))凈化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)粉(fen)(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)流(liu)分離。負極(ji)(ji)由(you)不(bu)(bu)同斷面形(xing)狀(zhuang)的(de)金屬導線制成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)(bu)同幾何形(xing)狀(zhuang)的(de)金屬板(ban)制成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)性能(neng)受粉(fen)(fen)塵(chen)(chen)(chen)性質、設備構造和煙氣(qi)流(liu)速等三(san)個因素(su)的(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性的(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)效率(lv)有(you)直接的(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)粒難(nan)以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使(shi)其重(zhong)返(fan)氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過高(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)現象(xiang)。這些情(qing)況(kuang)都會(hui)造成除(chu)(chu)塵(chen)(chen)(chen)效率(lv)下(xia)降。

電除塵(chen)器的(de)(de)(de)(de)基本(ben)原理是利用電力捕集煙氣中的(de)(de)(de)(de)粉(fen)塵(chen)，主(zhu)要包括以下四個相(xiang)互(hu)有關的(de)(de)(de)(de)物理過程: (1) 氣體(ti)(ti)的(de)(de)(de)(de)電離。(2) 粉(fen)塵(chen)的(de)(de)(de)(de)荷電。(3) 荷電粉(fen)塵(chen)向電極移動(dong)。(4) 荷電粉(fen)塵(chen)的(de)(de)(de)(de)捕集。
