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)(dian)(dian)除(chu)塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來收(shou)捕廢氣(qi)中(zhong)(zhong)(zhong)的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈化(hua)工作(zuo)上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)(he)沉淀兩個系統(tong)來完成的(de)(de)(de)，當含塵(chen)氣(qi)體(ti)(ti)進人(ren)氣(qi)刺叭時，含塵(chen)氣(qi)體(ti)(ti)受到氣(qi)流(liu)分布板(ban)以及(ji)折流(liu)板(ban)的(de)(de)(de)調整后(hou)(hou)，使(shi)(shi)氣(qi)流(liu)能(neng)較均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)作(zuo)用下(xia)，氣(qi)流(liu)速(su)度(du)迅速(su)降低，其中(zhong)(zhong)(zhong)有些較重的(de)(de)(de)塵(chen)粒(li)便失去速(su)度(du)而沉降下(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附(fu)近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)(hou)的(de)(de)(de)氣(qi)體(ti)(ti)中(zhong)(zhong)(zhong)存在(zai)大(da)量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)結合起來，使(shi)(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下(xia)趨向(xiang)本設(she)備陽(yang)極(ji)(正(zheng)極(ji)、本設(she)備采用負高壓制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設(she)備陰陽(yang)極(ji)振(zhen)打系統(tong)的(de)(de)(de)振(zhen)打，使(shi)(shi)沉積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)振(zhen)落(luo)，進人(ren)集(ji)灰斗 通過排灰裝置放(fang)出(chu)，回收(shou)有物料(liao)，被)凈化(hua)的(de)(de)(de)氣(qi)體(ti)(ti)排入(ru)大(da)氣(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的工作原理是利(li)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(liu)中的粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用下(xia)(xia)與氣(qi)流(liu)分離。負極由不(bu)同斷面形狀(zhuang)的金屬導線制成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正(zheng)極由不(bu)同幾(ji)何形狀(zhuang)的金屬板制成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構造(zao)和煙(yan)氣(qi)流(liu)速等三(san)個因素的影(ying)響。粉(fen)塵(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的指標，它對除(chu)(chu)塵(chen)(chen)效率有直(zhi)接(jie)的影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒難(nan)以(yi)保(bao)持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出，在塵(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部(bu)擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象(xiang)。這(zhe)些情況都會造(zao)成(cheng)(cheng)除(chu)(chu)塵(chen)(chen)效率下(xia)(xia)降。

電(dian)(dian)除塵(chen)(chen)器的(de)基本原理是利用電(dian)(dian)力捕(bu)(bu)集煙氣中的(de)粉塵(chen)(chen)，主(zhu)要包括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)向(xiang)電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵(chen)(chen)的(de)捕(bu)(bu)集。
