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)除塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)是以(yi)靜電(dian)凈(jing)化法來(lai)收(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)化工作(zuo)上要(yao)是依(yi)靠電(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和(he)(he)沉淀兩個系(xi)統(tong)來(lai)完成的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進人(ren)(ren)(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流分布(bu)板以(yi)及折(zhe)流板的(de)(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流能較均勻地進人(ren)(ren)(ren)(ren)(ren)電(dian)場(chang)。在橫斷(duan)面(mian)擴(kuo)大的(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)(qi)(qi)流速度迅速降低，其(qi)中有些較重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒(li)便失去(qu)速度而沉降下來(lai)。進人(ren)(ren)(ren)(ren)(ren)電(dian)場(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通人(ren)(ren)(ren)(ren)(ren)高(gao)壓(ya)(ya)直(zhi)流電(dian)，則(ze)在電(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附近產生電(dian)暈(yun)現(xian)象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)離(li)，電(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中存在大量的(de)(de)(de)(de)(de)電(dian)子(zi)和(he)(he)離(li)子(zi)，這些電(dian)子(zi)和(he)(he)離(li)子(zi)與進人(ren)(ren)(ren)(ren)(ren)電(dian)場(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)結(jie)合(he)起來(lai)，使塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒(li)帶(dai)電(dian)，帶(dai)電(dian)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)粒(li)在電(dian)場(chang)力的(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下趨向本設備(bei)陽極(ji)(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)(ji)、本設備(bei)采用(yong)(yong)負高(gao)壓(ya)(ya)制(zhi))和(he)(he)陰(yin)極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)子(zi)分別沉積在相(xiang)應的(de)(de)(de)(de)(de)電(dian)極(ji)(ji)(ji)(ji)(ji)上，通過設備(bei)陰(yin)陽極(ji)(ji)(ji)(ji)(ji)振(zhen)(zhen)打(da)系(xi)統(tong)的(de)(de)(de)(de)(de)振(zhen)(zhen)打(da)，使沉積在陰(yin)陽電(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進人(ren)(ren)(ren)(ren)(ren)集(ji)灰斗 通過排灰裝置放(fang)出，回收(shou)有物料，被)凈(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理(li)是(shi)利用(yong)高(gao)壓電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用(yong)下與氣(qi)(qi)流分離(li)。負極由不(bu)同斷面形(xing)(xing)狀的(de)(de)(de)金(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不(bu)同幾(ji)何形(xing)(xing)狀的(de)(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質(zhi)、設備構造(zao)(zao)和煙(yan)氣(qi)(qi)流速等三(san)個因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除塵(chen)(chen)(chen)效率(lv)有(you)直接(jie)的(de)(de)(de)影響。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒(li)難以保(bao)持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使(shi)其(qi)重返氣(qi)(qi)流。比電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)層之間(jian)形(xing)(xing)成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部(bu)擊穿和放電(dian)(dian)(dian)現象。這些情(qing)況都(dou)會(hui)造(zao)(zao)成(cheng)除塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)(dian)除塵(chen)器(qi)的基(ji)本原(yuan)理是利用電(dian)(dian)(dian)力捕集煙氣中的粉(fen)塵(chen)，主(zhu)要包括以下四個相互有關的物理過程: (1) 氣體(ti)的電(dian)(dian)(dian)離(li)。(2) 粉(fen)塵(chen)的荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)的捕集。
