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)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)化工作上要是依(yi)靠(kao)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉淀兩個系(xi)統來完成的(de)(de)(de)(de)(de)，當(dang)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體受(shou)到氣(qi)(qi)(qi)流分布板以及折流板的(de)(de)(de)(de)(de)調整(zheng)后(hou)，使氣(qi)(qi)(qi)流能較均(jun)勻(yun)地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴大(da)(da)的(de)(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)流速(su)度迅速(su)降(jiang)(jiang)低，其中有(you)些較重的(de)(de)(de)(de)(de)塵(chen)(chen)粒便失去(qu)速(su)度而沉降(jiang)(jiang)下(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)(ya)直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體中存(cun)在大(da)(da)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)結(jie)合起來，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作用下(xia)趨向本(ben)設備(bei)(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)(bei)采用負(fu)高壓(ya)(ya)制)和(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積(ji)在相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過設備(bei)(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振(zhen)打(da)系(xi)統的(de)(de)(de)(de)(de)振(zhen)打(da)，使沉積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)振(zhen)落，進(jin)人(ren)(ren)集灰斗 通(tong)過排灰裝(zhuang)置(zhi)放出，回(hui)收有(you)物料(liao)，被)凈(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體排入大(da)(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作原(yuan)理是利(li)用(yong)高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下(xia)與氣(qi)流(liu)分離。負極(ji)(ji)由不(bu)同斷(duan)面(mian)形(xing)狀(zhuang)的(de)(de)金屬導線制(zhi)成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不(bu)同幾何形(xing)狀(zhuang)的(de)(de)金屬板(ban)制(zhi)成，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設(she)備(bei)構造(zao)和煙氣(qi)流(liu)速等三個因素的(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對(dui)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接(jie)的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放出(chu)，在塵(chen)(chen)(chen)(chen)(chen)層之間(jian)形(xing)成電(dian)(dian)(dian)(dian)壓梯度會(hui)產生局(ju)部(bu)擊穿和放電(dian)(dian)(dian)(dian)現(xian)象。這些情況都會(hui)造(zao)成除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效率(lv)下(xia)降。
