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)除塵(chen)(chen)(chen)器(qi)是(shi)以靜電(dian)凈(jing)(jing)化(hua)法(fa)來(lai)收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的粉塵(chen)(chen)(chen)，它的凈(jing)(jing)化(hua)工作(zuo)上(shang)(shang)要是(shi)依靠(kao)電(dian)暈極(ji)(ji)(ji)(ji)和沉淀(dian)兩個(ge)系統(tong)來(lai)完成的，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流(liu)分布(bu)板以及折流(liu)板的調整(zheng)后(hou)，使(shi)(shi)氣(qi)(qi)(qi)(qi)流(liu)能較均勻地進人(ren)(ren)電(dian)場。在(zai)橫斷面擴大的作(zuo)用下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速(su)(su)(su)度迅(xun)速(su)(su)(su)降低，其(qi)中(zhong)有(you)些(xie)較重的塵(chen)(chen)(chen)粒便(bian)失去速(su)(su)(su)度而沉降下(xia)來(lai)。進人(ren)(ren)電(dian)場的含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)暈極(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直流(liu)電(dian)，則在(zai)電(dian)暈極(ji)(ji)(ji)(ji)附近產生電(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)離，電(dian)離后(hou)的氣(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)大量的電(dian)子和離子，這些(xie)電(dian)子和離子與進人(ren)(ren)電(dian)場的粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)，帶(dai)電(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)場力的作(zuo)用下(xia)趨向本設備陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備采用負高壓(ya)制(zhi))和陰(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋(shi)放(fang)出電(dian)子分別(bie)沉積(ji)在(zai)相(xiang)應的電(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)，通(tong)過(guo)設備陰(yin)陽(yang)極(ji)(ji)(ji)(ji)振(zhen)(zhen)打系統(tong)的振(zhen)(zhen)打，使(shi)(shi)沉積(ji)在(zai)陰(yin)陽(yang)電(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)的粉塵(chen)(chen)(chen)振(zhen)(zhen)落，進人(ren)(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放(fang)出，回(hui)收有(you)物料，被(bei))凈(jing)(jing)化(hua)的氣(qi)(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)工(gong)作原理是利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)分離(li)。負極(ji)(ji)由(you)不同斷面形狀(zhuang)(zhuang)的(de)(de)(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀(zhuang)(zhuang)的(de)(de)(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構(gou)造(zao)和煙氣(qi)流(liu)速等三個因素(su)的(de)(de)(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以(yi)保持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使(shi)其重(zhong)返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出(chu)，在(zai)(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會產生局部(bu)擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵器的基本原理(li)是利(li)用(yong)電(dian)力捕集煙氣中(zhong)的粉(fen)塵，主(zhu)要包括以下四個(ge)相互有(you)關(guan)的物理(li)過程: (1) 氣體的電(dian)離。(2) 粉(fen)塵的荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)塵向電(dian)極(ji)移動。(4) 荷(he)(he)電(dian)粉(fen)塵的捕集。
