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)(dian)除(chu)塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)(lai)收捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)凈化(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和(he)沉淀兩個(ge)系統來(lai)(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)體進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)(liu)分布(bu)板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)(de)(de)調(diao)整后，使氣(qi)(qi)流(liu)(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷(duan)面擴大(da)的(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)流(liu)(liu)速度迅(xun)速降(jiang)低，其中有些較重的(de)(de)(de)(de)塵(chen)粒便失去(qu)速度而沉降(jiang)下(xia)來(lai)(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通人(ren)(ren)高(gao)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)體中存在(zai)(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉塵(chen)結(jie)合起來(lai)(lai)，使塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作(zuo)用下(xia)趨(qu)向本設備陽極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設備采用負高(gao)壓制)和(he)陰極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分別沉積(ji)在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上，通過(guo)設備陰陽極(ji)(ji)(ji)(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)振(zhen)(zhen)打，使沉積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)振(zhen)(zhen)落，進(jin)(jin)人(ren)(ren)集灰斗 通過(guo)排灰裝置放出，回收有物料(liao)，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)體排入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作原理是利用(yong)高(gao)壓電(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場(chang)作用(yong)下與(yu)氣(qi)流分離。負(fu)極由不(bu)同斷面形(xing)狀的(de)金(jin)屬(shu)導線(xian)制成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不(bu)同幾何(he)形(xing)狀的(de)金(jin)屬(shu)板(ban)制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質(zhi)、設備構造(zao)和煙(yan)氣(qi)流速等三個因素的(de)影響。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)(chen)效率(lv)(lv)有直接的(de)影響。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重(zhong)返氣(qi)流。比(bi)電(dian)(dian)(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯(ti)度(du)會產生局(ju)部擊(ji)穿和放電(dian)(dian)(dian)現象。這些(xie)情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)效率(lv)(lv)下降。

電(dian)(dian)除塵器的基本原理(li)是利用電(dian)(dian)力捕集煙氣(qi)中的粉塵，主要包括以下四個相互(hu)有(you)關的物理(li)過(guo)程(cheng): (1) 氣(qi)體的電(dian)(dian)離。(2) 粉塵的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的捕集。
