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(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈化(hua)工作(zuo)上要(yao)是(shi)依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)和(he)沉淀兩個系(xi)統來(lai)完成的(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及(ji)折流(liu)板的(de)(de)(de)(de)調(diao)整后，使氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降低(di)，其中有(you)些較(jiao)重的(de)(de)(de)(de)塵(chen)粒(li)便(bian)失去速度(du)而沉降下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)通人(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)附近(jin)產(chan)生電(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體中存在(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這些電(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)結合起(qi)來(lai)，使塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用(yong)下趨向本(ben)設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負(fu)高(gao)壓制)和(he)陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋(shi)放(fang)(fang)出電(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積(ji)在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設(she)備(bei)陰陽(yang)極(ji)(ji)(ji)振(zhen)(zhen)打(da)系(xi)統的(de)(de)(de)(de)振(zhen)(zhen)打(da)，使沉積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落，進(jin)(jin)人(ren)集(ji)灰(hui)斗 通過(guo)排灰(hui)裝置放(fang)(fang)出，回收(shou)有(you)物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入大(da)氣(qi)(qi)(qi)(qi)。

工作(zuo)原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)工(gong)作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中(zhong)的(de)(de)粉(fen)(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)(qi)流分離(li)。負極(ji)(ji)由不同(tong)(tong)斷面(mian)形(xing)狀的(de)(de)金(jin)屬導線制成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)(tong)幾何形(xing)狀的(de)(de)金(jin)屬板(ban)制成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)性(xing)能受粉(fen)(fen)塵(chen)性(xing)質(zhi)、設備(bei)構(gou)造和煙氣(qi)(qi)流速(su)等三個因素的(de)(de)影(ying)響。粉(fen)(fen)塵(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指(zhi)標，它(ta)對除塵(chen)效(xiao)率(lv)有(you)直接(jie)的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)粒(li)難(nan)以保(bao)持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重返氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出(chu)，在塵(chen)層(ceng)之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產(chan)生局部擊(ji)穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)(cheng)除塵(chen)效(xiao)率(lv)下降。

電(dian)(dian)除(chu)塵(chen)器(qi)的(de)基本原(yuan)理是(shi)利用電(dian)(dian)力捕(bu)集煙氣中的(de)粉(fen)(fen)(fen)塵(chen)，主(zhu)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)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)(fen)(fen)塵(chen)的(de)捕(bu)集。
