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(shi)靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法(fa)來收(shou)捕(bu)廢氣(qi)中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極和沉(chen)淀兩(liang)個(ge)系統(tong)來完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)體進(jin)人氣(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)體受到氣(qi)流分布板以及(ji)折流板的(de)(de)(de)(de)調整后(hou)，使氣(qi)流能較均(jun)勻地(di)進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)流速(su)度(du)迅速(su)降低(di)，其中有(you)些(xie)較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)粒便失去(qu)速(su)度(du)而沉(chen)降下(xia)來。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)體由(you)于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通(tong)人高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)體中存在(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與(yu)進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合(he)起來，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下(xia)趨向(xiang)本(ben)設(she)備陽(yang)極(正極、本(ben)設(she)備采用負高(gao)壓制)和陰(yin)極(負極) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通(tong)過設(she)備陰(yin)陽(yang)極振(zhen)(zhen)打系統(tong)的(de)(de)(de)(de)振(zhen)(zhen)打，使沉(chen)積在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振(zhen)(zhen)落，進(jin)人集(ji)灰斗 通(tong)過排灰裝置放出，回收(shou)有(you)物(wu)料，被(bei))凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)體排入大氣(qi)。

工作原(yuan)理(li)

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工(gong)作(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)(dian)場使煙(yan)(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)用下(xia)(xia)與(yu)氣(qi)流分離。負極由不(bu)同(tong)斷面形(xing)狀(zhuang)(zhuang)的(de)(de)(de)金(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不(bu)同(tong)幾何形(xing)狀(zhuang)(zhuang)的(de)(de)(de)金(jin)屬板(ban)制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)(chen)性(xing)質、設備(bei)構造(zao)和(he)煙(yan)(yan)氣(qi)流速等三(san)個因素(su)的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率(lv)有直(zhi)接的(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)流。比(bi)(bi)電(dian)(dian)(dian)(dian)阻過高，到(dao)達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)(he)不(bu)易(yi)放出，在塵(chen)(chen)(chen)(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿(chuan)和(he)放電(dian)(dian)(dian)(dian)現象。這些情(qing)況都(dou)會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率(lv)下(xia)(xia)降。
