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)(dian)除(chu)塵(chen)(chen)器是(shi)(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈化法來收捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈化工作(zuo)上(shang)要(yao)是(shi)(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀(dian)兩個系統來完成的(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)(qi)(qi)流分(fen)布板(ban)以(yi)及折流板(ban)的(de)(de)調整(zheng)后(hou)(hou)，使(shi)氣(qi)(qi)(qi)(qi)(qi)流能較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流速度迅速降(jiang)低(di)，其(qi)中有些較(jiao)重的(de)(de)塵(chen)(chen)粒便(bian)失去(qu)速度而沉(chen)降(jiang)下來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人(ren)(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)(hou)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中存(cun)在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下趨向本(ben)設(she)(she)備(bei)(bei)陽(yang)(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設(she)(she)備(bei)(bei)采用(yong)負(fu)高(gao)壓制)和陰(yin)(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設(she)(she)備(bei)(bei)陰(yin)(yin)陽(yang)(yang)極(ji)(ji)振打(da)系統的(de)(de)振打(da)，使(shi)沉(chen)積在(zai)陰(yin)(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)(chen)振落，進(jin)人(ren)(ren)集灰斗 通(tong)過排灰裝置放出(chu)，回(hui)收有物料，被)凈化的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)工作(zuo)原理是利用(yong)高壓電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離(li)，氣流(liu)(liu)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用(yong)下與氣流(liu)(liu)分離(li)。負極(ji)由不同斷面形狀的(de)(de)(de)(de)(de)金(jin)屬導(dao)線制成(cheng)(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形狀的(de)(de)(de)(de)(de)金(jin)屬板(ban)制成(cheng)(cheng)(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備(bei)構造和(he)煙氣流(liu)(liu)速等三個因素的(de)(de)(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性(xing)(xing)的(de)(de)(de)(de)(de)指標，它(ta)對除(chu)(chu)(chu)塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以(yi)保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使其重返氣流(liu)(liu)。比電(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)層之(zhi)間形成(cheng)(cheng)(cheng)電(dian)(dian)(dian)壓梯(ti)度會(hui)產(chan)生局部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)現象。這些(xie)情(qing)況都會(hui)造成(cheng)(cheng)(cheng)除(chu)(chu)(chu)塵(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵器的(de)(de)基本(ben)原理是利(li)用(yong)電(dian)力捕(bu)集(ji)煙(yan)氣(qi)(qi)中的(de)(de)粉塵，主要包括以下四個相互有關的(de)(de)物(wu)理過程: (1) 氣(qi)(qi)體(ti)的(de)(de)電(dian)離。(2) 粉塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移動(dong)。(4) 荷電(dian)粉塵的(de)(de)捕(bu)集(ji)。
