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)(dian)除塵(chen)(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)化(hua)工(gong)作上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和沉淀兩個系統來完(wan)成(cheng)的(de)(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流(liu)(liu)分(fen)布板以(yi)及折流(liu)(liu)板的(de)(de)(de)(de)(de)調整后(hou)，使(shi)(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均(jun)勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴(kuo)大(da)的(de)(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速度(du)迅速降(jiang)(jiang)低，其中有(you)些較重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去速度(du)而沉降(jiang)(jiang)下(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與(yu)進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合起(qi)來，使(shi)(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作用下(xia)趨向本設備陽(yang)(yang)極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設備采用負(fu)高壓制)和陰極(ji)(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別(bie)沉積在(zai)(zai)相(xiang)應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上，通過設備陰陽(yang)(yang)極(ji)(ji)(ji)(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)(de)振(zhen)(zhen)打，使(shi)(shi)沉積在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進人(ren)集灰斗 通過排灰裝(zhuang)置放(fang)出，回(hui)收有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)除塵(chen)器的(de)(de)(de)工作原理是利(li)用(yong)高壓電(dian)(dian)場使煙氣(qi)發生電(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉塵(chen)荷電(dian)(dian)在電(dian)(dian)場作用(yong)下(xia)與氣(qi)流分離。負極(ji)(ji)由不(bu)同斷面形(xing)狀的(de)(de)(de)金屬(shu)導(dao)線(xian)制成，叫(jiao)(jiao)放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何(he)形(xing)狀的(de)(de)(de)金屬(shu)板制成，叫(jiao)(jiao)集塵(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除塵(chen)器的(de)(de)(de)性(xing)能受粉塵(chen)性(xing)質(zhi)、設備構(gou)造和(he)煙氣(qi)流速等三個因(yin)素的(de)(de)(de)影響。粉塵(chen)的(de)(de)(de)比(bi)電(dian)(dian)阻是評價導(dao)電(dian)(dian)性(xing)的(de)(de)(de)指(zhi)標，它對除塵(chen)效率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)粒難(nan)以保持在集塵(chen)電(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流。比(bi)電(dian)(dian)阻過(guo)高，到達集塵(chen)電(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)粒電(dian)(dian)荷不(bu)易放出，在塵(chen)層之間形(xing)成電(dian)(dian)壓梯度會產生局部擊(ji)穿和(he)放電(dian)(dian)現象。這(zhe)些情況都會造成除塵(chen)效率下(xia)降。

電(dian)除塵(chen)器的(de)基本原理是利用(yong)電(dian)力捕(bu)集煙氣中的(de)粉(fen)(fen)塵(chen)，主要包括以(yi)下四個相互有關(guan)的(de)物理過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)(fen)塵(chen)的(de)捕(bu)集。
