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)除(chu)塵(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)，它的(de)(de)凈(jing)化(hua)工(gong)作(zuo)上(shang)要是依靠(kao)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)沉淀兩(liang)個(ge)系統來(lai)完成的(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)體進(jin)(jin)(jin)人(ren)(ren)(ren)(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流分布板(ban)以(yi)及折流板(ban)的(de)(de)調整后(hou)(hou)，使氣(qi)(qi)(qi)流能(neng)較均勻地(di)進(jin)(jin)(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴大的(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)(qi)流速度迅速降(jiang)(jiang)低，其中(zhong)有些較重的(de)(de)塵(chen)粒便失去速度而(er)沉降(jiang)(jiang)下(xia)來(lai)。進(jin)(jin)(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)(ren)(ren)(ren)高壓直流電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)(qi)體電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)(hou)的(de)(de)氣(qi)(qi)(qi)體中(zhong)存在(zai)(zai)大量的(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)(jin)(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)結合起(qi)來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下(xia)趨(qu)向本設(she)備(bei)陽(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)備(bei)采用(yong)負高壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分別沉積在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設(she)備(bei)陰陽(yang)極(ji)(ji)振(zhen)(zhen)打系統的(de)(de)振(zhen)(zhen)打，使沉積在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)振(zhen)(zhen)落(luo)，進(jin)(jin)(jin)人(ren)(ren)(ren)(ren)集(ji)灰斗 通過排(pai)(pai)灰裝置放出，回收有物(wu)料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)體排(pai)(pai)入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)工作原理是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用下(xia)(xia)與氣流(liu)分(fen)離。負極(ji)(ji)由(you)不(bu)同(tong)斷面形狀(zhuang)的(de)(de)(de)金(jin)屬導線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同(tong)幾何形狀(zhuang)的(de)(de)(de)金(jin)屬板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)(chen)性質、設備(bei)構造(zao)和(he)煙氣流(liu)速等(deng)三個因(yin)素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評(ping)價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它(ta)對(dui)除塵(chen)(chen)效率有直接(jie)的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)低，塵(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生局(ju)部擊(ji)穿和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造(zao)成(cheng)除塵(chen)(chen)效率下(xia)(xia)降。
