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(jing)電(dian)(dian)除(chu)塵(chen)器是以靜(jing)電(dian)(dian)凈(jing)化法來收(shou)捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈(jing)化工作上(shang)(shang)要是依靠電(dian)(dian)暈(yun)(yun)極和沉(chen)淀兩(liang)個(ge)系統來完(wan)成(cheng)的(de)(de)(de)，當(dang)含塵(chen)氣(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分(fen)布板(ban)以及(ji)折流(liu)板(ban)的(de)(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)能較(jiao)均勻地進人電(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)(de)作用(yong)(yong)下(xia)，氣(qi)(qi)(qi)流(liu)速度(du)迅速降(jiang)低，其中(zhong)有些較(jiao)重的(de)(de)(de)塵(chen)粒(li)便(bian)失(shi)去速度(du)而沉(chen)降(jiang)下(xia)來。進人電(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)暈(yun)(yun)極通(tong)人高壓直流(liu)電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)(yun)極附近產生電(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)子和離(li)子，這些電(dian)(dian)子和離(li)子與(yu)進人電(dian)(dian)場的(de)(de)(de)粉塵(chen)結合(he)起來，使塵(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)場力的(de)(de)(de)作用(yong)(yong)下(xia)趨(qu)向(xiang)本設備陽(yang)極(正極、本設備采用(yong)(yong)負高壓制)和陰極(負極) ， 釋放(fang)出電(dian)(dian)子分(fen)別沉(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)極上(shang)(shang)，通(tong)過設備陰陽(yang)極振打(da)(da)系統的(de)(de)(de)振打(da)(da)，使沉(chen)積在(zai)(zai)陰陽(yang)電(dian)(dian)極上(shang)(shang)的(de)(de)(de)粉塵(chen)振落，進人集(ji)灰斗 通(tong)過排(pai)灰裝置放(fang)出，回(hui)收(shou)有物料(liao)，被)凈(jing)化的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(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)(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原理是(shi)利(li)用高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用下與氣流(liu)分離。負極(ji)由不同(tong)斷面形(xing)狀的(de)(de)(de)金屬導(dao)線制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何(he)形(xing)狀的(de)(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質(zhi)、設(she)備構造和煙(yan)氣流(liu)速(su)等三個因素(su)的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒難以保(bao)持(chi)在(zai)集塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返(fan)氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)效率(lv)下降(jiang)。

電(dian)(dian)除(chu)塵(chen)(chen)器的基本原理是利(li)用(yong)電(dian)(dian)力捕集煙氣中的粉塵(chen)(chen)，主要(yao)包括以下四個相互有關的物理過程(cheng): (1) 氣體(ti)的電(dian)(dian)離。(2) 粉塵(chen)(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵(chen)(chen)的捕集。
