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)(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法(fa)來(lai)收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)工(gong)作上要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)淀兩個系(xi)統(tong)(tong)來(lai)完成(cheng)的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受(shou)到氣(qi)(qi)流分布(bu)板以及折流板的(de)(de)(de)調整后，使氣(qi)(qi)流能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)。在橫斷(duan)面(mian)擴大的(de)(de)(de)作用下，氣(qi)(qi)流速(su)度迅速(su)降低，其中有(you)些(xie)較重的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)便失(shi)去速(su)度而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)高壓直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附(fu)近(jin)產生(sheng)電(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)中存在大量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與(yu)進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合(he)起來(lai)，使塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)在電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)力的(de)(de)(de)作用下趨向本(ben)設(she)備(bei)(bei)陽(yang)(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備(bei)(bei)采用負高壓制)和(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設(she)備(bei)(bei)陰(yin)陽(yang)(yang)極(ji)(ji)(ji)振打系(xi)統(tong)(tong)的(de)(de)(de)振打，使沉(chen)積在陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振落，進(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝置(zhi)放出，回收(shou)有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器的工作原理(li)是(shi)利用高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下(xia)與氣(qi)流(liu)分離(li)。負極(ji)由不同斷面形(xing)狀的金屬導線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同幾(ji)何形(xing)狀的金屬板制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器的性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備(bei)構造和煙氣(qi)流(liu)速等(deng)三(san)個因素的影響。粉(fen)塵(chen)(chen)的比電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)的指標，它(ta)對除(chu)(chu)(chu)塵(chen)(chen)效(xiao)率有直接的影響。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)粒(li)難(nan)以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)高，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)層(ceng)之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)現象。這(zhe)些情況(kuang)都會(hui)造成(cheng)除(chu)(chu)(chu)塵(chen)(chen)效(xiao)率下(xia)降。

電除塵(chen)器(qi)的基本原理是利用(yong)電力捕集煙氣(qi)中(zhong)的粉(fen)塵(chen)，主要包括(kuo)以(yi)下四(si)個(ge)相互有關的物理過程: (1) 氣(qi)體的電離。(2) 粉(fen)塵(chen)的荷電。(3) 荷電粉(fen)塵(chen)向電極移(yi)動。(4) 荷電粉(fen)塵(chen)的捕集。
