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)(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化法來(lai)收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)(de)凈(jing)(jing)化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極和(he)沉(chen)淀兩個系統來(lai)完成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)體進(jin)人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體受到(dao)氣(qi)(qi)流(liu)(liu)分(fen)布板(ban)以及折(zhe)流(liu)(liu)板(ban)的(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)流(liu)(liu)能(neng)較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)流(liu)(liu)速(su)度迅(xun)速(su)降低，其中有(you)些較(jiao)重(zhong)的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速(su)度而沉(chen)降下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極通人(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)(yun)極附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)(qi)體中存在(zai)(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)作用下(xia)趨向本設(she)備陽(yang)極(正(zheng)極、本設(she)備采用負高壓制)和(he)陰(yin)(yin)極(負極) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積(ji)在(zai)(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通過設(she)備陰(yin)(yin)陽(yang)極振(zhen)打系統的(de)(de)(de)(de)振(zhen)打，使(shi)沉(chen)積(ji)在(zai)(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)人(ren)集(ji)灰(hui)斗 通過排灰(hui)裝置放(fang)出，回收(shou)有(you)物(wu)料(liao)，被)凈(jing)(jing)化的(de)(de)(de)(de)氣(qi)(qi)體排入大(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)工作(zuo)原理(li)是利用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分離(li)。負極由(you)不(bu)同斷面(mian)形狀(zhuang)的(de)(de)金屬(shu)(shu)導線(xian)制成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同幾(ji)何形狀(zhuang)的(de)(de)金屬(shu)(shu)板(ban)制成，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)性(xing)能受(shou)粉(fen)(fen)塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備(bei)構(gou)造(zao)和煙氣(qi)流速等(deng)三個因(yin)素的(de)(de)影響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)(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)指標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有(you)直接的(de)(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易(yi)放出(chu)，在塵(chen)(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情況(kuang)都會造(zao)成除(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降(jiang)。

電(dian)(dian)(dian)(dian)除塵器的基(ji)本原理是利用電(dian)(dian)(dian)(dian)力捕集煙(yan)氣(qi)中(zhong)的粉(fen)塵，主要包(bao)括以(yi)下四個相互(hu)有(you)關的物理過程: (1) 氣(qi)體(ti)的電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵的荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵的捕集。
