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(shi)靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)器(qi)是以(yi)靜(jing)電(dian)(dian)(dian)凈(jing)化法來(lai)收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化工(gong)作上(shang)要是依靠電(dian)(dian)(dian)暈(yun)極和沉(chen)淀(dian)兩個系(xi)(xi)統來(lai)完(wan)成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體進(jin)人(ren)氣(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分(fen)(fen)布板以(yi)及折流(liu)板的(de)(de)(de)調整(zheng)后(hou)，使(shi)(shi)(shi)氣(qi)(qi)流(liu)能較均(jun)勻地進(jin)人(ren)電(dian)(dian)(dian)場(chang)。在橫(heng)斷面擴(kuo)大的(de)(de)(de)作用下，氣(qi)(qi)流(liu)速(su)度(du)(du)迅速(su)降低，其中有些較重的(de)(de)(de)塵(chen)(chen)粒(li)便失去(qu)速(su)度(du)(du)而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由(you)于電(dian)(dian)(dian)暈(yun)極通人(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極附(fu)近(jin)產生電(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)(shi)氣(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)體中存在大量(liang)的(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些電(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合起(qi)來(lai)，使(shi)(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下趨(qu)向本設備陽(yang)極(正極、本設備采(cai)用負高(gao)壓(ya)制)和陰極(負極) ， 釋放(fang)(fang)出電(dian)(dian)(dian)子(zi)(zi)分(fen)(fen)別(bie)沉(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)極上(shang)，通過設備陰陽(yang)極振打系(xi)(xi)統的(de)(de)(de)振打，使(shi)(shi)(shi)沉(chen)積在陰陽(yang)電(dian)(dian)(dian)極上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)集灰斗(dou) 通過排灰裝置放(fang)(fang)出，回收(shou)有物(wu)料，被)凈(jing)化的(de)(de)(de)氣(qi)(qi)體排入大氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場作用下(xia)與氣流(liu)(liu)分離。負(fu)極(ji)由不(bu)同斷面形(xing)狀的(de)(de)(de)金屬導(dao)線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾(ji)何形(xing)狀的(de)(de)(de)金屬板制成(cheng)，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設(she)備(bei)構造和煙氣流(liu)(liu)速(su)等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除塵(chen)效(xiao)率有直接(jie)的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)粒難以保持在(zai)集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達(da)集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易(yi)放出(chu)，在(zai)塵(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會(hui)造成(cheng)除塵(chen)效(xiao)率下(xia)降。

電(dian)除(chu)塵器的(de)(de)基(ji)本原(yuan)理(li)(li)是利用電(dian)力捕(bu)集(ji)煙氣中的(de)(de)粉(fen)塵，主要包括以(yi)下四個相互有關的(de)(de)物理(li)(li)過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向電(dian)極移動。(4) 荷電(dian)粉(fen)塵的(de)(de)捕(bu)集(ji)。
