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)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)凈化(hua)工作上要(yao)是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和沉(chen)(chen)淀兩個系統(tong)來(lai)完成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)分布(bu)板(ban)以及折流(liu)板(ban)的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)能較均勻地進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫(heng)斷面擴大(da)的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降低，其中(zhong)有些較重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去速度(du)而沉(chen)(chen)降下(xia)來(lai)。進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通(tong)(tong)人(ren)高(gao)壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)子(zi)(zi)(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)子(zi)(zi)(zi)與進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用下(xia)趨向本設(she)備陽(yang)極(ji)(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)(ji)、本設(she)備采(cai)用負高(gao)壓(ya)制)和陰極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別沉(chen)(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上，通(tong)(tong)過(guo)設(she)備陰陽(yang)極(ji)(ji)(ji)(ji)(ji)振(zhen)(zhen)打系統(tong)的(de)(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)(chen)積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進人(ren)集灰斗 通(tong)(tong)過(guo)排(pai)灰裝置(zhi)放出，回收(shou)(shou)有物料(liao)，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)(qi)(qi)(qi)。

工作原理

靜(jing)(jing)電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)(de)工作原理是利用(yong)高壓(ya)(ya)電(dian)(dian)場(chang)(chang)使煙氣(qi)發生電(dian)(dian)離(li)，氣(qi)流中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)(chang)作用(yong)下(xia)與氣(qi)流分(fen)離(li)。負(fu)極(ji)(ji)由不(bu)(bu)同斷面形(xing)狀的(de)(de)(de)(de)金屬(shu)導線(xian)制成，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)(bu)同幾何形(xing)狀的(de)(de)(de)(de)金屬(shu)板(ban)制成，叫集(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)。靜(jing)(jing)電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)(de)性能受粉(fen)塵(chen)(chen)性質、設備構造和(he)煙氣(qi)流速等三(san)個因素的(de)(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)阻是評價導電(dian)(dian)性的(de)(de)(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)效(xiao)率(lv)(lv)有直接的(de)(de)(de)(de)影響(xiang)。比電(dian)(dian)阻過(guo)低，塵(chen)(chen)粒(li)難以保(bao)持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)上，致(zhi)使其重返氣(qi)流。比電(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)荷不(bu)(bu)易放出，在(zai)塵(chen)(chen)層之間形(xing)成電(dian)(dian)壓(ya)(ya)梯度會(hui)產生局(ju)部擊穿和(he)放電(dian)(dian)現象。這些情況都會(hui)造成除(chu)塵(chen)(chen)效(xiao)率(lv)(lv)下(xia)降。

電(dian)(dian)除塵(chen)器的(de)基本(ben)原理是利用(yong)電(dian)(dian)力捕集(ji)煙氣中(zhong)的(de)粉(fen)塵(chen)，主(zhu)要包(bao)括以下四個相(xiang)互有關的(de)物理過(guo)程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)的(de)捕集(ji)。
