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)(dian)除(chu)塵(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)工作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極和(he)沉(chen)淀兩個(ge)系(xi)(xi)統來完成(cheng)的(de)(de)(de)，當(dang)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)分布板(ban)以及折流(liu)(liu)(liu)板(ban)的(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)能較均勻(yun)地(di)進人(ren)電(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴大的(de)(de)(de)作用下(xia)(xia)，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度(du)迅速(su)降低，其中(zhong)(zhong)有(you)些(xie)較重的(de)(de)(de)塵(chen)(chen)粒便失(shi)去速(su)度(du)而沉(chen)降下(xia)(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)暈極通(tong)(tong)人(ren)高(gao)壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈極附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中(zhong)(zhong)存在大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)(chen)結合起來，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下(xia)(xia)趨向本(ben)設(she)備(bei)陽(yang)(yang)極(正極、本(ben)設(she)備(bei)采用負(fu)高(gao)壓制)和(he)陰(yin)極(負(fu)極) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上(shang)，通(tong)(tong)過設(she)備(bei)陰(yin)陽(yang)(yang)極振打(da)系(xi)(xi)統的(de)(de)(de)振打(da)，使沉(chen)積在陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進人(ren)集灰斗(dou) 通(tong)(tong)過排(pai)灰裝置放出，回收有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)(qi)。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作原理是(shi)利用高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣發生電(dian)(dian)(dian)(dian)離(li)，氣流中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場作用下與氣流分離(li)。負(fu)極由不(bu)(bu)同(tong)斷面形(xing)狀(zhuang)的(de)(de)金(jin)屬導線(xian)制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不(bu)(bu)同(tong)幾何(he)形(xing)狀(zhuang)的(de)(de)金(jin)屬板制成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造(zao)(zao)和(he)(he)煙氣流速等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是(shi)評(ping)價導電(dian)(dian)(dian)(dian)性的(de)(de)指標，它對(dui)除塵(chen)(chen)(chen)(chen)效率(lv)有直接(jie)的(de)(de)影響。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使(shi)其重返氣流。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)(he)不(bu)(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)(chen)層之(zhi)間(jian)形(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生局部擊(ji)穿和(he)(he)放電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)(zao)成除塵(chen)(chen)(chen)(chen)效率(lv)下降。

電除塵(chen)(chen)器的(de)(de)(de)基本原理(li)是利用(yong)電力捕集煙氣(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，主要包括以下四(si)個相互有關的(de)(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)(de)電離。(2) 粉(fen)塵(chen)(chen)的(de)(de)(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)(chen)向(xiang)電極移動。(4) 荷(he)電粉(fen)塵(chen)(chen)的(de)(de)(de)捕集。
