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)除塵器是(shi)以靜電(dian)(dian)(dian)凈(jing)化(hua)(hua)法來收捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉塵，它的(de)(de)(de)凈(jing)化(hua)(hua)工作上(shang)要是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀(dian)兩個系(xi)(xi)統來完成的(de)(de)(de)，當含塵氣(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含塵氣(qi)(qi)(qi)(qi)(qi)體(ti)受(shou)到(dao)氣(qi)(qi)(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流能(neng)較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面(mian)擴大(da)的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)(qi)流速度迅速降低，其(qi)中(zhong)有(you)些較(jiao)重的(de)(de)(de)塵粒便失去速度而沉降下(xia)來。進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含塵氣(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通(tong)人(ren)高壓直流電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)子和(he)離(li)子與進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵結合起來，使(shi)塵粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵粒在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用下(xia)趨(qu)向本設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采用負高壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分(fen)別(bie)沉積(ji)在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)設(she)備陰(yin)陽(yang)極(ji)(ji)振打系(xi)(xi)統的(de)(de)(de)振打，使(shi)沉積(ji)在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵振落，進(jin)人(ren)集灰(hui)斗 通(tong)過(guo)排(pai)(pai)灰(hui)裝置放(fang)出，回收有(you)物(wu)料(liao)，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排(pai)(pai)入大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)器的(de)工作原理(li)是利用(yong)高壓電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)粉塵(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作用(yong)下(xia)與氣(qi)(qi)流分(fen)離。負極(ji)由不同斷面形(xing)(xing)狀(zhuang)的(de)金(jin)屬(shu)導線(xian)制(zhi)成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形(xing)(xing)狀(zhuang)的(de)金(jin)屬(shu)板(ban)制(zhi)成(cheng)，叫集塵(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)器的(de)性(xing)(xing)能受粉塵(chen)性(xing)(xing)質、設備構造和煙(yan)氣(qi)(qi)流速(su)等三個因素(su)的(de)影響(xiang)。粉塵(chen)的(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性(xing)(xing)的(de)指標，它對除塵(chen)效率有直(zhi)接的(de)影響(xiang)。比電(dian)(dian)(dian)阻過低，塵(chen)粒難以保持在(zai)(zai)集塵(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其(qi)重返氣(qi)(qi)流。比電(dian)(dian)(dian)阻過高，到達(da)集塵(chen)電(dian)(dian)(dian)極(ji)的(de)塵(chen)粒電(dian)(dian)(dian)荷不易放出(chu)，在(zai)(zai)塵(chen)層之(zhi)間形(xing)(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生局(ju)部(bu)擊穿和放電(dian)(dian)(dian)現象。這些情(qing)況(kuang)都會造成(cheng)除塵(chen)效率下(xia)降。

電(dian)(dian)除塵(chen)(chen)器(qi)的(de)基本(ben)原理是利用電(dian)(dian)力捕(bu)集煙氣中的(de)粉(fen)(fen)(fen)塵(chen)(chen)，主要包括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)(fen)(fen)塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)(fen)塵(chen)(chen)向(xiang)電(dian)(dian)極(ji)移(yi)動。(4) 荷電(dian)(dian)粉(fen)(fen)(fen)塵(chen)(chen)的(de)捕(bu)集。
