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(shi)靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)(qi)中的(de)粉(fen)塵(chen)(chen)，它(ta)的(de)凈化工作上要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)沉(chen)淀兩個(ge)系統來(lai)完(wan)成的(de)，當(dang)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)分(fen)布(bu)板以(yi)及折流(liu)板的(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)流(liu)能較(jiao)均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面(mian)擴大的(de)作用(yong)下，氣(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有些較(jiao)重(zhong)的(de)塵(chen)(chen)粒(li)便(bian)失去速(su)度而沉(chen)降下來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)體(ti)(ti)中存在(zai)(zai)大量的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作用(yong)下趨向本設備陽(yang)極(ji)(正極(ji)、本設備采用(yong)負高壓(ya)制)和(he)陰極(ji)(負極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積(ji)在(zai)(zai)相應(ying)的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設備陰陽(yang)極(ji)振打系統的(de)振打，使(shi)沉(chen)積(ji)在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)粉(fen)塵(chen)(chen)振落，進(jin)人集灰(hui)斗 通過排灰(hui)裝(zhuang)置放出，回收有物料，被)凈化的(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是(shi)利用高(gao)壓電(dian)(dian)場使煙氣(qi)發生(sheng)電(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作(zuo)用下與(yu)氣(qi)流(liu)分離。負極(ji)由(you)不(bu)同斷面形(xing)狀的(de)(de)(de)金屬(shu)導線(xian)制成，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同幾何形(xing)狀的(de)(de)(de)金屬(shu)板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備構造(zao)和煙氣(qi)流(liu)速等三個(ge)因素(su)的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)性(xing)(xing)的(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)效率有直接(jie)的(de)(de)(de)影響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難(nan)以保持在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)。比電(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不(bu)易(yi)放出，在塵(chen)(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)壓梯度會(hui)產生(sheng)局部擊(ji)穿和放電(dian)(dian)現象(xiang)。這(zhe)些情況(kuang)都會(hui)造(zao)成除塵(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵器的(de)(de)(de)基本原理是利用電(dian)(dian)力捕集(ji)煙氣中的(de)(de)(de)粉(fen)(fen)塵，主要包括以下四個相互有關(guan)的(de)(de)(de)物理過程: (1) 氣體(ti)的(de)(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵的(de)(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉(fen)(fen)塵的(de)(de)(de)捕集(ji)。
