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(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法(fa)來收捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀(dian)兩個系統來完成的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進(jin)(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)(liu)分布板以(yi)及折流(liu)(liu)(liu)(liu)板的(de)(de)(de)(de)調(diao)整后(hou)，使(shi)(shi)氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)(liu)能較均勻地進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)(liu)速度迅速降低，其中有些較重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失(shi)去速度而(er)沉降下來。進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)通人(ren)(ren)(ren)高(gao)壓(ya)直(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體中存(cun)在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起來，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用下趨向本(ben)(ben)設(she)備(bei)陽(yang)極(ji)(正(zheng)極(ji)、本(ben)(ben)設(she)備(bei)采(cai)用負高(gao)壓(ya)制(zhi))和(he)陰極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子(zi)分別沉積(ji)在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設(she)備(bei)陰陽(yang)極(ji)振打(da)系統的(de)(de)(de)(de)振打(da)，使(shi)(shi)沉積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)(jin)人(ren)(ren)(ren)集灰斗 通過排(pai)灰裝置放出(chu)，回收有物料，被)凈(jing)化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體排(pai)入大氣(qi)(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用下(xia)與(yu)氣(qi)(qi)流(liu)分離。負(fu)極(ji)由(you)(you)不(bu)同斷(duan)面(mian)形狀的(de)(de)(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)(you)不(bu)同幾(ji)何形狀的(de)(de)(de)(de)金(jin)屬板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備(bei)構造和煙氣(qi)(qi)流(liu)速等三個因素(su)的(de)(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效(xiao)率有直(zhi)接(jie)的(de)(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以(yi)保(bao)持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會(hui)產生局部擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象。這些(xie)情況都會(hui)造成(cheng)除塵(chen)(chen)(chen)(chen)效(xiao)率下(xia)降。

電(dian)除塵(chen)(chen)器的(de)基本原理是利用電(dian)力捕(bu)集煙氣(qi)中的(de)粉塵(chen)(chen)，主要包括以下(xia)四個(ge)相互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向電(dian)極移動。(4) 荷電(dian)粉塵(chen)(chen)的(de)捕(bu)集。
