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)除(chu)塵(chen)器是(shi)以靜電(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)(lai)收捕廢氣(qi)中(zhong)的(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)，它的(de)(de)(de)(de)(de)凈(jing)(jing)化(hua)工作上要是(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)(chen)淀兩個(ge)系(xi)統(tong)來(lai)(lai)完成(cheng)的(de)(de)(de)(de)(de)，當含(han)(han)塵(chen)氣(qi)體進(jin)人(ren)氣(qi)刺(ci)叭時(shi)，含(han)(han)塵(chen)氣(qi)體受到(dao)氣(qi)流分布板(ban)以及折流板(ban)的(de)(de)(de)(de)(de)調(diao)整(zheng)后，使(shi)氣(qi)流能較(jiao)均勻(yun)地進(jin)人(ren)電(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)(de)作用下，氣(qi)流速度迅速降低(di)，其(qi)中(zhong)有些(xie)較(jiao)重(zhong)的(de)(de)(de)(de)(de)塵(chen)粒(li)便(bian)失去速度而沉(chen)(chen)降下來(lai)(lai)。進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)(han)塵(chen)氣(qi)體由(you)于電(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高(gao)(gao)壓直流電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)(de)氣(qi)體中(zhong)存在(zai)(zai)大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和離子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)結(jie)合起來(lai)(lai)，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作用下趨向(xiang)本設備(bei)(bei)陽(yang)(yang)極(ji)(正極(ji)、本設備(bei)(bei)采用負(fu)高(gao)(gao)壓制)和陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積在(zai)(zai)相(xiang)應(ying)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通過(guo)設備(bei)(bei)陰陽(yang)(yang)極(ji)振打系(xi)統(tong)的(de)(de)(de)(de)(de)振打，使(shi)沉(chen)(chen)積在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)振落，進(jin)人(ren)集灰(hui)斗 通過(guo)排灰(hui)裝(zhuang)置放出，回收有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)(de)(de)氣(qi)體排入大氣(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原理是利(li)用高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流分離。負極(ji)由(you)不同(tong)斷面(mian)形(xing)(xing)狀的(de)(de)(de)金屬導線制成，叫(jiao)(jiao)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形(xing)(xing)狀的(de)(de)(de)金屬板制成，叫(jiao)(jiao)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(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和煙氣(qi)流速(su)等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)(xiao)率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)(shi)其重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達(da)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)(chen)層之(zhi)間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產(chan)生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象(xiang)。這些情況(kuang)都會(hui)造(zao)成除(chu)塵(chen)(chen)(chen)(chen)效(xiao)(xiao)率下(xia)降。
