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(wo)式靜(jing)(jing)電(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)(jing)電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩(liang)個系統來(lai)(lai)完成的(de)(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流分布(bu)板以(yi)及折流板的(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)(qi)流能較(jiao)(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷(duan)面擴大(da)的(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)(qi)流速(su)度(du)迅速(su)降低，其(qi)中(zhong)有些較(jiao)(jiao)重的(de)(de)(de)塵(chen)(chen)粒便(bian)失(shi)去(qu)速(su)度(du)而沉降下來(lai)(lai)。進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)高壓(ya)直流電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作(zuo)用下趨向本設(she)備陽極(ji)(ji)(正極(ji)(ji)、本設(she)備采(cai)用負(fu)高壓(ya)制)和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)子(zi)分別沉積(ji)在(zai)(zai)(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過(guo)設(she)備陰陽極(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)振(zhen)打(da)，使沉積(ji)在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振(zhen)落(luo)，進(jin)人(ren)集灰斗(dou) 通過(guo)排(pai)灰裝(zhuang)置放(fang)出(chu)，回收有物(wu)料(liao)，被(bei))凈(jing)化的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排(pai)入(ru)大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)除塵(chen)(chen)器的工作原理是(shi)(shi)利用高壓(ya)電(dian)場使煙氣發生電(dian)離，氣流中的粉塵(chen)(chen)荷(he)電(dian)在電(dian)場作用下與氣流分離。負(fu)極由不(bu)同(tong)(tong)斷(duan)面形(xing)狀的金(jin)屬導(dao)線制成(cheng)，叫放(fang)電(dian)電(dian)極。正極由不(bu)同(tong)(tong)幾何形(xing)狀的金(jin)屬板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)極。靜(jing)電(dian)除塵(chen)(chen)器的性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和(he)煙氣流速等三個因素的影響。粉塵(chen)(chen)的比(bi)電(dian)阻(zu)是(shi)(shi)評(ping)價導(dao)電(dian)性(xing)的指標，它(ta)對除塵(chen)(chen)效率(lv)有直接的影響。比(bi)電(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)極上，致使其重返氣流。比(bi)電(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)電(dian)極的塵(chen)(chen)粒電(dian)荷(he)不(bu)易放(fang)出，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)壓(ya)梯(ti)度會(hui)產生局部擊穿(chuan)和(he)放(fang)電(dian)現象(xiang)。這些情況都會(hui)造成(cheng)除塵(chen)(chen)效率(lv)下降(jiang)。

電(dian)(dian)除(chu)塵器的基本(ben)原理(li)是利用(yong)電(dian)(dian)力捕(bu)集煙氣中的粉(fen)塵，主要包括以下(xia)四個相互(hu)有關的物理(li)過程: (1) 氣體(ti)的電(dian)(dian)離。(2) 粉(fen)塵的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵的捕(bu)集。
