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)(chen)(chen)器是以靜電(dian)(dian)凈化法來(lai)收(shou)捕廢氣中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)凈化工(gong)作上(shang)(shang)(shang)要是依靠電(dian)(dian)暈(yun)(yun)極和(he)沉淀兩(liang)個系統(tong)來(lai)完成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣體進(jin)(jin)人(ren)氣刺叭時，含塵(chen)(chen)(chen)氣體受到氣流(liu)分(fen)布板以及(ji)折流(liu)板的(de)(de)(de)調整后(hou)，使氣流(liu)能較均勻地進(jin)(jin)人(ren)電(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)作用(yong)下，氣流(liu)速度迅速降低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速度而沉降下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)含塵(chen)(chen)(chen)氣體由于電(dian)(dian)暈(yun)(yun)極通(tong)人(ren)高壓直流(liu)電(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)暈(yun)(yun)極附近產(chan)生電(dian)(dian)暈(yun)(yun)現象(xiang)，使氣體電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)氣體中存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)子和(he)離(li)(li)子，這(zhe)些電(dian)(dian)子和(he)離(li)(li)子與進(jin)(jin)人(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合起來(lai)，使塵(chen)(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)作用(yong)下趨(qu)向本設備陽極(正極、本設備采用(yong)負(fu)高壓制(zhi))和(he)陰極(負(fu)極) ， 釋放(fang)出電(dian)(dian)子分(fen)別沉積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)極上(shang)(shang)(shang)，通(tong)過設備陰陽極振打系統(tong)的(de)(de)(de)振打，使沉積在(zai)(zai)陰陽電(dian)(dian)極上(shang)(shang)(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振落(luo)，進(jin)(jin)人(ren)集灰(hui)斗 通(tong)過排灰(hui)裝(zhuang)置放(fang)出，回收(shou)有物料，被(bei))凈化的(de)(de)(de)氣體排入大(da)氣。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的工作原理(li)是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)(qi)流(liu)(liu)中的粉(fen)塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)(qi)(qi)流(liu)(liu)分離(li)。負極(ji)由(you)不同(tong)(tong)斷面(mian)形狀的金屬(shu)導(dao)線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不同(tong)(tong)幾何形狀的金屬(shu)板(ban)制(zhi)成(cheng)，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的性(xing)能(neng)受粉(fen)塵(chen)(chen)性(xing)質、設備構造(zao)和(he)煙氣(qi)(qi)(qi)流(liu)(liu)速(su)等三個因素的影響。粉(fen)塵(chen)(chen)的比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的指標，它(ta)對除塵(chen)(chen)效(xiao)率有直接的影響。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣(qi)(qi)(qi)流(liu)(liu)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)(he)不易(yi)放出，在塵(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都(dou)會造(zao)成(cheng)除塵(chen)(chen)效(xiao)率下降。

電(dian)除塵(chen)器的(de)(de)(de)基本原理(li)是利用(yong)電(dian)力捕(bu)集煙氣(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)，主要包(bao)括以下四(si)個相互有關的(de)(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)塵(chen)的(de)(de)(de)捕(bu)集。
