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)式靜電(dian)(dian)(dian)(dian)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕廢氣(qi)(qi)中(zhong)的(de)粉(fen)(fen)塵(chen)，它(ta)的(de)凈(jing)化(hua)工作(zuo)上要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極和(he)(he)沉淀兩(liang)個(ge)系統來完成的(de)，當含(han)塵(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)(jin)人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)流分布板以(yi)及折流板的(de)調整后，使(shi)氣(qi)(qi)流能(neng)較均勻地進(jin)(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)作(zuo)用下，氣(qi)(qi)流速度迅速降低，其中(zhong)有些較重的(de)塵(chen)粒(li)(li)便失(shi)去速度而(er)沉降下來。進(jin)(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)含(han)塵(chen)氣(qi)(qi)體(ti)(ti)由(you)于(yu)電(dian)(dian)(dian)(dian)暈(yun)極通(tong)人(ren)高壓直流電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)與(yu)進(jin)(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)粉(fen)(fen)塵(chen)結合(he)起來，使(shi)塵(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)作(zuo)用下趨向本(ben)(ben)設(she)備陽(yang)(yang)極(正極、本(ben)(ben)設(she)備采用負(fu)高壓制)和(he)(he)陰極(負(fu)極) ， 釋(shi)放(fang)出(chu)電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積(ji)在(zai)(zai)相應(ying)的(de)電(dian)(dian)(dian)(dian)極上，通(tong)過設(she)備陰陽(yang)(yang)極振打系統的(de)振打，使(shi)沉積(ji)在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)極上的(de)粉(fen)(fen)塵(chen)振落，進(jin)(jin)(jin)人(ren)集灰斗 通(tong)過排(pai)灰裝(zhuang)置放(fang)出(chu)，回收有物料，被(bei))凈(jing)化(hua)的(de)氣(qi)(qi)體(ti)(ti)排(pai)入大(da)氣(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)(de)工(gong)作原(yuan)理是利用高(gao)壓電(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用下(xia)(xia)與氣(qi)(qi)流分離。負極(ji)(ji)由不同斷面形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金屬導(dao)線(xian)制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不同幾(ji)何形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金屬板(ban)制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備構(gou)造(zao)和(he)煙氣(qi)(qi)流速等三個因素的(de)(de)(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指(zhi)標，它對(dui)除塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)(de)(de)影響。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)(qi)流。比電(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度(du)會(hui)產生局部擊穿和(he)放(fang)電(dian)(dian)(dian)現象。這些(xie)情況都會(hui)造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率下(xia)(xia)降。
