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)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)凈(jing)(jing)化(hua)法來收捕廢氣(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)要是依靠(kao)電(dian)(dian)暈極(ji)和(he)沉(chen)淀(dian)兩個系(xi)(xi)統來完(wan)成的(de)(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)進(jin)人氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)受到氣(qi)流(liu)分布板以及(ji)折流(liu)板的(de)(de)(de)(de)調整(zheng)后，使(shi)氣(qi)流(liu)能較均勻地進(jin)人電(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)(da)的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)流(liu)速度迅速降低，其中(zhong)有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速度而沉(chen)降下來。進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)由于電(dian)(dian)暈極(ji)通(tong)人高壓直流(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈極(ji)附近(jin)產(chan)生電(dian)(dian)暈現象(xiang)，使(shi)氣(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后的(de)(de)(de)(de)氣(qi)體(ti)(ti)中(zhong)存在(zai)大(da)(da)量的(de)(de)(de)(de)電(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)子(zi)和(he)離子(zi)與(yu)進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下趨向(xiang)本設(she)(she)備陽(yang)極(ji)(正(zheng)極(ji)、本設(she)(she)備采用(yong)負高壓制)和(he)陰極(ji)(負極(ji)) ， 釋(shi)放出(chu)電(dian)(dian)子(zi)分別沉(chen)積在(zai)相應的(de)(de)(de)(de)電(dian)(dian)極(ji)上(shang)，通(tong)過(guo)設(she)(she)備陰陽(yang)極(ji)振打(da)系(xi)(xi)統的(de)(de)(de)(de)振打(da)，使(shi)沉(chen)積在(zai)陰陽(yang)電(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)人集灰斗 通(tong)過(guo)排灰裝置放出(chu)，回收有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)(de)氣(qi)體(ti)(ti)排入大(da)(da)氣(qi)。

工作原理(li)

靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)工作原理是利用高(gao)壓電(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)離(li)，氣(qi)流中的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣(qi)流分離(li)。負極(ji)由不(bu)同斷面形(xing)(xing)狀(zhuang)的(de)金屬(shu)導線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形(xing)(xing)狀(zhuang)的(de)金屬(shu)板制(zhi)成(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)性能受(shou)粉塵(chen)(chen)(chen)(chen)性質、設備構(gou)造(zao)和煙(yan)氣(qi)流速等三個因(yin)素的(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)阻是評(ping)價導電(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)(chen)效率有(you)直接(jie)的(de)影(ying)響(xiang)。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以(yi)保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣(qi)流。比電(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出(chu)，在塵(chen)(chen)(chen)(chen)層之間(jian)形(xing)(xing)成(cheng)(cheng)電(dian)(dian)壓梯度會(hui)產(chan)生局部擊穿(chuan)和放電(dian)(dian)現象。這些(xie)情況(kuang)都會(hui)造(zao)成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)器的(de)基本原理(li)是利用(yong)電(dian)(dian)(dian)力捕(bu)集煙氣中的(de)粉(fen)塵(chen)，主要包括以下(xia)四個相互有關的(de)物理(li)過(guo)程: (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)的(de)捕(bu)集。
