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)除(chu)塵(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)凈化法來(lai)收捕廢氣(qi)中(zhong)的粉塵(chen)(chen)(chen)，它(ta)的凈化工作(zuo)(zuo)上(shang)要是依靠電(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩個系統來(lai)完成的，當(dang)含塵(chen)(chen)(chen)氣(qi)體進(jin)人(ren)(ren)氣(qi)刺(ci)叭時(shi)，含塵(chen)(chen)(chen)氣(qi)體受到氣(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的調整后，使(shi)氣(qi)流(liu)(liu)能(neng)較均勻地進(jin)人(ren)(ren)電(dian)(dian)場。在橫斷面(mian)擴(kuo)大(da)的作(zuo)(zuo)用下(xia)，氣(qi)流(liu)(liu)速(su)度(du)迅速(su)降低，其中(zhong)有(you)(you)些較重的塵(chen)(chen)(chen)粒便(bian)失去速(su)度(du)而(er)沉降下(xia)來(lai)。進(jin)人(ren)(ren)電(dian)(dian)場的含塵(chen)(chen)(chen)氣(qi)體由(you)于電(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)高壓(ya)直(zhi)流(liu)(liu)電(dian)(dian)，則在電(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生電(dian)(dian)暈(yun)現象，使(shi)氣(qi)體電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的氣(qi)體中(zhong)存在大(da)量的電(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些電(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)場的粉塵(chen)(chen)(chen)結(jie)合(he)起(qi)來(lai)，使(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)場力的作(zuo)(zuo)用下(xia)趨向本(ben)設備(bei)陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備(bei)采用負(fu)高壓(ya)制)和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)子(zi)(zi)分別沉積在相應(ying)的電(dian)(dian)極(ji)(ji)上(shang)，通過(guo)(guo)設備(bei)陰陽極(ji)(ji)振(zhen)(zhen)打系統的振(zhen)(zhen)打，使(shi)沉積在陰陽電(dian)(dian)極(ji)(ji)上(shang)的粉塵(chen)(chen)(chen)振(zhen)(zhen)落(luo)，進(jin)人(ren)(ren)集灰斗 通過(guo)(guo)排灰裝置放(fang)出，回收有(you)(you)物料，被)凈化的氣(qi)體排入大(da)氣(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的工作原理是(shi)利(li)用高壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)(liu)中的粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流(liu)(liu)分(fen)離(li)。負極(ji)(ji)由不同斷面形(xing)狀的金屬導(dao)線制成，叫放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形(xing)狀的金屬板(ban)制成，叫集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的性能受(shou)粉塵(chen)(chen)性質、設備構造和煙氣(qi)流(liu)(liu)速等三個因素的影響(xiang)。粉塵(chen)(chen)的比電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評(ping)價導(dao)電(dian)(dian)(dian)(dian)性的指標(biao)，它對除塵(chen)(chen)效率有(you)直接的影響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒難以保持在(zai)集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達(da)集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)(fang)出，在(zai)塵(chen)(chen)層(ceng)之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生局部(bu)擊穿(chuan)和放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會造成除塵(chen)(chen)效率下(xia)降。

電(dian)除塵(chen)(chen)器(qi)的(de)(de)基(ji)本原理是利用電(dian)力(li)捕集(ji)(ji)煙氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)，主(zhu)要包括以下四個相互有關的(de)(de)物(wu)理過程: (1) 氣(qi)體(ti)的(de)(de)電(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷(he)(he)(he)電(dian)。(3) 荷(he)(he)(he)電(dian)粉(fen)塵(chen)(chen)向電(dian)極移動。(4) 荷(he)(he)(he)電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集(ji)(ji)。
