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(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕(bu)廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)粉(fen)(fen)塵(chen)，它的(de)凈化工作上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)和沉(chen)淀兩個(ge)系統(tong)(tong)來(lai)完成(cheng)的(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時(shi)，含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流分(fen)布(bu)板以(yi)及折(zhe)流板的(de)調(diao)整后(hou)(hou)，使(shi)氣(qi)(qi)(qi)(qi)流能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫(heng)斷面擴大的(de)作用下，氣(qi)(qi)(qi)(qi)流速度迅速降低，其中(zhong)有(you)些較重的(de)塵(chen)粒便失去速度而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)通人(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)(hou)的(de)氣(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)(zai)(zai)大量的(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(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)(fen)塵(chen)結合起來(lai)，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作用下趨向(xiang)本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設(she)備(bei)采用負(fu)高壓(ya)制)和陰(yin)(yin)極(ji)(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積在(zai)(zai)(zai)相應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)(shang)，通過設(she)備(bei)陰(yin)(yin)陽(yang)極(ji)(ji)(ji)(ji)(ji)振(zhen)打系統(tong)(tong)的(de)振(zhen)打，使(shi)沉(chen)積在(zai)(zai)(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)(shang)的(de)粉(fen)(fen)塵(chen)振(zhen)落，進(jin)人(ren)集灰(hui)斗(dou) 通過排灰(hui)裝置放出(chu)，回收有(you)物料，被(bei))凈化的(de)氣(qi)(qi)(qi)(qi)體(ti)排入(ru)大氣(qi)(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)工作(zuo)原(yuan)理是(shi)利用高壓(ya)電(dian)場(chang)使煙(yan)(yan)氣(qi)發生(sheng)(sheng)電(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)荷電(dian)在(zai)電(dian)場(chang)作(zuo)用下與氣(qi)流(liu)分離(li)。負(fu)極(ji)由(you)不(bu)(bu)同(tong)斷面形(xing)狀的(de)(de)(de)金(jin)屬導(dao)線制成(cheng)，叫放(fang)電(dian)電(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同(tong)幾(ji)何形(xing)狀的(de)(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)電(dian)極(ji)。靜(jing)電(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)性質、設(she)備構造和煙(yan)(yan)氣(qi)流(liu)速等三個因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)的(de)(de)(de)比電(dian)阻是(shi)評價導(dao)電(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)效率有(you)直接的(de)(de)(de)影(ying)響。比電(dian)阻過低，塵(chen)粒難以保持在(zai)集塵(chen)電(dian)極(ji)上，致使其(qi)重(zhong)返氣(qi)流(liu)。比電(dian)阻過高，到達集塵(chen)電(dian)極(ji)的(de)(de)(de)塵(chen)粒電(dian)荷不(bu)(bu)易(yi)放(fang)出，在(zai)塵(chen)層之(zhi)間形(xing)成(cheng)電(dian)壓(ya)梯度會產生(sheng)(sheng)局部(bu)擊穿和放(fang)電(dian)現象。這些(xie)情況都會造成(cheng)除(chu)塵(chen)效率下降(jiang)。

電(dian)除塵器的(de)(de)基本原理(li)是利(li)用電(dian)力(li)捕(bu)集(ji)煙氣中的(de)(de)粉塵，主要包括以下(xia)四個相(xiang)互有(you)關的(de)(de)物理(li)過程: (1) 氣體(ti)的(de)(de)電(dian)離。(2) 粉塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移(yi)動。(4) 荷電(dian)粉塵的(de)(de)捕(bu)集(ji)。
