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(wo)式靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)器是以(yi)(yi)靜(jing)電(dian)(dian)(dian)(dian)凈化法(fa)來收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩(liang)個系統來完成的(de)(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)體進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分布板(ban)以(yi)(yi)及折流(liu)板(ban)的(de)(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴大的(de)(de)(de)(de)(de)作用下，氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降低，其中有些較重的(de)(de)(de)(de)(de)塵(chen)粒便失去速(su)度(du)而沉(chen)降下來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)附(fu)近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)體中存在大量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)(dian)子和離(li)子與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)結合起來，使(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)(de)(de)作用下趨向本(ben)設(she)備陽(yang)(yang)極(ji)(正極(ji)、本(ben)設(she)備采用負高壓制)和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過設(she)備陰(yin)陽(yang)(yang)極(ji)振打(da)(da)系統的(de)(de)(de)(de)(de)振打(da)(da)，使(shi)沉(chen)積(ji)在陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)振落，進(jin)人(ren)(ren)集灰斗 通過排灰裝置放出，回收(shou)有物料，被)凈化的(de)(de)(de)(de)(de)氣(qi)(qi)體排入大氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的工作(zuo)(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作(zuo)(zuo)用下與(yu)氣(qi)流(liu)分(fen)離。負(fu)極(ji)由不同斷(duan)面形(xing)狀的金屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形(xing)狀的金屬板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的性能受粉(fen)塵(chen)(chen)性質(zhi)、設備構造和煙(yan)氣(qi)流(liu)速(su)等三個因素(su)的影(ying)響。粉(fen)塵(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)(dian)性的指標(biao)，它對除(chu)塵(chen)(chen)效率(lv)有直接的影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以(yi)保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放出(chu)，在(zai)塵(chen)(chen)層(ceng)之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)(hui)造成(cheng)除(chu)塵(chen)(chen)效率(lv)下降(jiang)。

電除塵(chen)器的(de)(de)基本原理是(shi)利用(yong)電力捕集(ji)(ji)煙氣中的(de)(de)粉塵(chen)，主要包括以下四個相(xiang)互(hu)有關(guan)的(de)(de)物理過(guo)程: (1) 氣體的(de)(de)電離。(2) 粉塵(chen)的(de)(de)荷電。(3) 荷電粉塵(chen)向電極移(yi)動。(4) 荷電粉塵(chen)的(de)(de)捕集(ji)(ji)。
