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(shi)靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)凈化法來(lai)收(shou)捕廢(fei)氣(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈化工作上(shang)要(yao)是(shi)依靠(kao)電(dian)(dian)(dian)(dian)暈極和(he)沉(chen)(chen)淀兩個系統(tong)來(lai)完成的(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受(shou)到氣(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及折流(liu)板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能(neng)較(jiao)均勻(yun)地進人(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷(duan)面(mian)擴大(da)的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)流(liu)速度(du)迅速降低，其中有(you)些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速度(du)而沉(chen)(chen)降下(xia)來(lai)。進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)暈極通(tong)(tong)人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極附近(jin)產生電(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中存在(zai)(zai)大(da)量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)結合起(qi)來(lai)，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下(xia)趨向本(ben)設備陽(yang)極(正極、本(ben)設備采用負高壓制)和(he)陰極(負極) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積(ji)在(zai)(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)極上(shang)，通(tong)(tong)過設備陰陽(yang)極振(zhen)打(da)系統(tong)的(de)(de)(de)振(zhen)打(da)，使(shi)沉(chen)(chen)積(ji)在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進人(ren)集(ji)灰斗 通(tong)(tong)過排灰裝(zhuang)置放出，回收(shou)有(you)物料，被)凈化的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的工作原理(li)是利(li)用(yong)(yong)高壓(ya)電(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)(yong)下與氣(qi)流分(fen)離(li)。負極由(you)不同斷(duan)面形狀的金屬導(dao)線制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)不同幾何形狀的金屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備(bei)構造(zao)(zao)和(he)煙(yan)氣(qi)流速(su)等三個(ge)因(yin)素的影響。粉塵(chen)(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的指標，它對除(chu)塵(chen)(chen)(chen)(chen)效率有直接的影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使(shi)其重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之(zhi)間(jian)形成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)現象。這(zhe)些(xie)情況都(dou)會造(zao)(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電除(chu)塵(chen)(chen)器(qi)的(de)基本(ben)原理(li)是利用電力捕集煙氣中(zhong)的(de)粉塵(chen)(chen)，主要包括(kuo)以下四(si)個相互有關的(de)物理(li)過(guo)程: (1) 氣體(ti)的(de)電離。(2) 粉塵(chen)(chen)的(de)荷電。(3) 荷電粉塵(chen)(chen)向電極移動(dong)。(4) 荷電粉塵(chen)(chen)的(de)捕集。
