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)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)(chen)淀兩個系統(tong)來(lai)完成的(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人氣(qi)(qi)刺(ci)叭時，含塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分(fen)布板以(yi)及折(zhe)流板的(de)(de)調整后，使氣(qi)(qi)流能較(jiao)均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴(kuo)大的(de)(de)作(zuo)(zuo)用下(xia)，氣(qi)(qi)流速度(du)迅速降(jiang)低，其中有些較(jiao)重的(de)(de)塵(chen)(chen)粒便失去速度(du)而沉(chen)(chen)降(jiang)下(xia)來(lai)。進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人高(gao)壓(ya)直(zhi)流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)中存(cun)在(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結(jie)合起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)(zuo)用下(xia)趨向本(ben)設備(bei)(bei)(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)(bei)(bei)采用負高(gao)壓(ya)制)和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設備(bei)(bei)(bei)陰陽(yang)極(ji)(ji)(ji)振打(da)系統(tong)的(de)(de)振打(da)，使沉(chen)(chen)積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)振落，進(jin)人集(ji)灰斗 通過排灰裝置放出，回收有物(wu)料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)排入(ru)大氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作(zuo)原理(li)是利用(yong)高(gao)壓電(dian)(dian)(dian)場使煙氣(qi)發(fa)生電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用(yong)下與氣(qi)流分離。負極由(you)不(bu)同斷面形狀的(de)(de)金屬導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不(bu)同幾何形狀的(de)(de)金屬板制成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質(zhi)、設備構造(zao)和(he)(he)煙氣(qi)流速等三(san)個因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難(nan)以(yi)保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)流。比電(dian)(dian)(dian)阻過高(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)(chen)層(ceng)之間(jian)形成電(dian)(dian)(dian)壓梯度會產生局部擊穿和(he)(he)放電(dian)(dian)(dian)現象。這些情況都會造(zao)成除塵(chen)(chen)(chen)效率下降(jiang)。

電(dian)除塵(chen)器的(de)基(ji)本原理是利(li)用電(dian)力捕集(ji)煙氣(qi)(qi)中的(de)粉塵(chen)，主要(yao)包括(kuo)以(yi)下四個相互有關的(de)物理過程(cheng): (1) 氣(qi)(qi)體(ti)的(de)電(dian)離(li)。(2) 粉塵(chen)的(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)向電(dian)極移動。(4) 荷電(dian)粉塵(chen)的(de)捕集(ji)。
