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)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)凈(jing)化法來(lai)收(shou)捕廢氣(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)凈(jing)化工作上(shang)要是依靠電(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩(liang)個系統來(lai)完成的(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)進(jin)(jin)人氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流分(fen)布板以及折流板的(de)(de)調整后(hou)，使氣(qi)流能(neng)較均勻地進(jin)(jin)人電(dian)(dian)(dian)場(chang)(chang)。在(zai)橫(heng)斷(duan)面(mian)擴大(da)的(de)(de)作用下(xia)，氣(qi)流速(su)度(du)迅(xun)速(su)降低，其中(zhong)有些較重的(de)(de)塵(chen)(chen)(chen)粒(li)便失去速(su)度(du)而沉(chen)降下(xia)來(lai)。進(jin)(jin)人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)通(tong)人高壓直流電(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)暈(yun)現(xian)象，使氣(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)體(ti)中(zhong)存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)子(zi)和離子(zi)與(yu)進(jin)(jin)人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合(he)起來(lai)，使塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用下(xia)趨(qu)向本設(she)(she)備陽(yang)(yang)極(ji)(正極(ji)、本設(she)(she)備采用負(fu)高壓制)和陰(yin)極(ji)(負(fu)極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通(tong)過(guo)(guo)設(she)(she)備陰(yin)陽(yang)(yang)極(ji)振打系統的(de)(de)振打，使沉(chen)積在(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進(jin)(jin)人集灰斗 通(tong)過(guo)(guo)排(pai)灰裝置放出，回收(shou)有物料，被)凈(jing)化的(de)(de)氣(qi)體(ti)排(pai)入(ru)大(da)氣(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的工作(zuo)原理是(shi)利(li)用(yong)高壓電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中的粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用(yong)下與(yu)氣(qi)流分離。負極由(you)不同斷(duan)面形狀的金(jin)屬導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不同幾何(he)形狀的金(jin)屬板制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的性能(neng)受粉塵(chen)(chen)(chen)(chen)性質、設備構造(zao)(zao)和煙氣(qi)流速等三(san)個因素的影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的指標(biao)，它對除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有(you)直接的影(ying)響(xiang)。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)粒難(nan)以(yi)保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產生局(ju)部擊穿和放(fang)電(dian)(dian)(dian)現象(xiang)。這(zhe)些情況都會(hui)造(zao)(zao)成(cheng)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵器的(de)(de)(de)基本(ben)原理是利用電(dian)(dian)力捕(bu)集(ji)煙氣(qi)中的(de)(de)(de)粉(fen)(fen)塵，主(zhu)要包(bao)括以(yi)下四個相(xiang)互有關的(de)(de)(de)物理過程: (1) 氣(qi)體(ti)的(de)(de)(de)電(dian)(dian)離(li)。(2) 粉(fen)(fen)塵的(de)(de)(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉(fen)(fen)塵向(xiang)電(dian)(dian)極移動(dong)。(4) 荷(he)(he)電(dian)(dian)粉(fen)(fen)塵的(de)(de)(de)捕(bu)集(ji)。
