XWD型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)(dian)除塵(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)中(zhong)(zhong)(zhong)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)(de)(de)凈(jing)化工(gong)作上(shang)要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和沉(chen)(chen)淀兩個系統來(lai)完成(cheng)的(de)(de)(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分(fen)布板(ban)(ban)以(yi)及折流(liu)(liu)板(ban)(ban)的(de)(de)(de)(de)(de)調整(zheng)后(hou)(hou)，使(shi)氣(qi)(qi)流(liu)(liu)能較(jiao)(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)(de)(de)(de)(de)作用下，氣(qi)(qi)流(liu)(liu)速(su)(su)度(du)迅速(su)(su)降(jiang)低(di)，其中(zhong)(zhong)(zhong)有些較(jiao)(jiao)重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失(shi)去(qu)速(su)(su)度(du)而沉(chen)(chen)降(jiang)下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)人(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)(zhong)(zhong)存在(zai)大量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作用下趨向(xiang)本(ben)設備(bei)陽(yang)極(ji)(正(zheng)極(ji)、本(ben)設備(bei)采(cai)用負(fu)高(gao)壓制)和陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)(chen)積在(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設備(bei)陰陽(yang)極(ji)振(zhen)(zhen)打(da)(da)系統的(de)(de)(de)(de)(de)振(zhen)(zhen)打(da)(da)，使(shi)沉(chen)(chen)積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落(luo)，進(jin)人(ren)集灰(hui)斗 通(tong)過排(pai)灰(hui)裝置放出，回(hui)收有物(wu)料，被(bei))凈(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)(de)工作(zuo)(zuo)原理(li)是利用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣發(fa)生電(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)(zuo)用下與(yu)氣流分離。負(fu)極(ji)(ji)(ji)由(you)不(bu)同斷面形(xing)(xing)狀的(de)(de)(de)金屬(shu)導(dao)線制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不(bu)同幾何形(xing)(xing)狀的(de)(de)(de)金屬(shu)板制成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設(she)備構造和(he)煙(yan)氣流速(su)等三個因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標(biao)，它對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使其重返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會(hui)產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)造成除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率下降。

電除塵(chen)器的基本原理(li)是利用(yong)電力(li)捕集(ji)煙氣(qi)中(zhong)的粉塵(chen)，主要包括以下(xia)四(si)個(ge)相互有關的物理(li)過程: (1) 氣(qi)體(ti)(ti)的電離(li)。(2) 粉塵(chen)的荷電。(3) 荷電粉塵(chen)向電極移動。(4) 荷電粉塵(chen)的捕集(ji)。
