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)除塵(chen)器是(shi)以靜電(dian)(dian)凈化(hua)法來(lai)(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)(zhong)的粉塵(chen)，它的凈化(hua)工(gong)作上要是(shi)依靠電(dian)(dian)暈(yun)極(ji)(ji)和(he)(he)沉淀(dian)兩(liang)個系統(tong)(tong)來(lai)(lai)完成的，當(dang)含(han)(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺(ci)叭時，含(han)(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)(liu)分布板(ban)以及折流(liu)(liu)(liu)板(ban)的調整后，使氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)(liu)能較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)場。在橫斷面擴(kuo)大(da)的作用下，氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)(liu)速(su)(su)度迅速(su)(su)降低，其中(zhong)(zhong)有些較(jiao)重的塵(chen)粒(li)便失去速(su)(su)度而沉降下來(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)場的含(han)(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)高(gao)壓直流(liu)(liu)(liu)電(dian)(dian)，則在電(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后的氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在大(da)量的電(dian)(dian)子(zi)和(he)(he)離子(zi)，這些電(dian)(dian)子(zi)和(he)(he)離子(zi)與進(jin)人(ren)(ren)電(dian)(dian)場的粉塵(chen)結合起來(lai)(lai)，使塵(chen)粒(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)粒(li)在電(dian)(dian)場力(li)的作用下趨(qu)向本設備(bei)陽(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本設備(bei)采(cai)用負高(gao)壓制)和(he)(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)子(zi)分別沉積在相應的電(dian)(dian)極(ji)(ji)上，通(tong)過設備(bei)陰陽(yang)極(ji)(ji)振(zhen)打(da)系統(tong)(tong)的振(zhen)打(da)，使沉積在陰陽(yang)電(dian)(dian)極(ji)(ji)上的粉塵(chen)振(zhen)落，進(jin)人(ren)(ren)集灰斗 通(tong)過排灰裝置放出，回(hui)收(shou)有物料，被)凈化(hua)的氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)工作原理是(shi)利用高(gao)壓電(dian)(dian)場使(shi)煙氣發生電(dian)(dian)離，氣流(liu)(liu)中的(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用下與氣流(liu)(liu)分離。負極由不(bu)同斷面形狀的(de)金(jin)屬(shu)導線制成，叫放電(dian)(dian)電(dian)(dian)極。正極由不(bu)同幾(ji)何形狀的(de)金(jin)屬(shu)板制成，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設(she)備構造和(he)(he)煙氣流(liu)(liu)速等三個因素(su)的(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)性(xing)的(de)指(zhi)標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有(you)直接的(de)影響。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒難(nan)以保持在(zai)集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極上，致(zhi)使(shi)其(qi)重返氣流(liu)(liu)。比電(dian)(dian)阻(zu)過高(gao)，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間(jian)形成電(dian)(dian)壓梯度會產生局(ju)部擊(ji)穿和(he)(he)放電(dian)(dian)現象。這些(xie)情(qing)況都(dou)會造成除塵(chen)(chen)(chen)(chen)(chen)效率下降。

電除(chu)塵(chen)器的(de)基本原理是利(li)用(yong)電力捕集煙氣(qi)中(zhong)的(de)粉(fen)塵(chen)，主要包括(kuo)以下四個(ge)相(xiang)互有(you)關的(de)物理過程: (1) 氣(qi)體的(de)電離。(2) 粉(fen)塵(chen)的(de)荷電。(3) 荷電粉(fen)塵(chen)向(xiang)電極移動。(4) 荷電粉(fen)塵(chen)的(de)捕集。
