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)除塵(chen)器(qi)是以靜電(dian)(dian)(dian)凈化法來收捕廢氣(qi)中(zhong)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)(de)(de)凈化工作上(shang)要是依靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩個系統來完成的(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)體(ti)進(jin)人(ren)(ren)氣(qi)刺叭時，含(han)塵(chen)氣(qi)體(ti)受到氣(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)(de)(de)(de)調整(zheng)后，使(shi)(shi)氣(qi)流(liu)能(neng)較均勻(yun)地進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)(zai)橫(heng)斷面擴大(da)的(de)(de)(de)(de)(de)(de)作用下(xia)，氣(qi)流(liu)速度迅速降低，其中(zhong)有些較重的(de)(de)(de)(de)(de)(de)塵(chen)粒便失(shi)去速度而沉降下(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)含(han)塵(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)通(tong)人(ren)(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附(fu)近產生電(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)中(zhong)存在(zai)(zai)(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)子和(he)離子與進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)結(jie)合起來，使(shi)(shi)塵(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)(de)作用下(xia)趨向本設(she)備陽極(ji)(正極(ji)、本設(she)備采用負(fu)(fu)高壓(ya)制)和(he)陰極(ji)(負(fu)(fu)極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子分別沉積在(zai)(zai)(zai)相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設(she)備陰陽極(ji)振打系統的(de)(de)(de)(de)(de)(de)振打，使(shi)(shi)沉積在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)振落，進(jin)人(ren)(ren)集灰斗 通(tong)過排(pai)(pai)灰裝置放出，回收有物料，被)凈化的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)排(pai)(pai)入大(da)氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作原理是(shi)利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)流(liu)分離(li)。負極(ji)(ji)由不同斷面形(xing)狀(zhuang)的(de)(de)金(jin)屬導線制成(cheng)(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形(xing)狀(zhuang)的(de)(de)金(jin)屬板制成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性質(zhi)、設備構造(zao)和煙氣(qi)流(liu)速等三個(ge)因素的(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響(xiang)。比(bi)(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流(liu)。比(bi)(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)(he)不易放出(chu)，在(zai)(zai)塵(chen)(chen)(chen)(chen)(chen)層(ceng)之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造(zao)成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率下降。
