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。

臥式靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢氣(qi)中的(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)凈(jing)化工(gong)作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)和(he)沉(chen)淀(dian)兩個系統來完(wan)成的(de)(de)，當(dang)含塵(chen)(chen)(chen)(chen)氣(qi)體(ti)進人氣(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)(liu)分布(bu)板以(yi)及(ji)折流(liu)(liu)(liu)板的(de)(de)調(diao)整后(hou)，使(shi)氣(qi)流(liu)(liu)(liu)能(neng)較均(jun)勻地進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴大(da)的(de)(de)作(zuo)用下，氣(qi)流(liu)(liu)(liu)速度迅速降低(di)，其(qi)中有(you)些較重的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便(bian)失(shi)去速度而沉(chen)降下來。進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)通人高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)附近(jin)產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象(xiang)，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)氣(qi)體(ti)中存在大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下趨(qu)向本設備(bei)陽(yang)極(ji)(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)(ji)、本設備(bei)采用負高壓制)和(he)陰(yin)極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積在相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上，通過設備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)(ji)(ji)振打系統的(de)(de)振打，使(shi)沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)(chen)振落(luo)，進人集灰斗(dou) 通過排灰裝置放出，回收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器的(de)(de)工(gong)作原理是利用高(gao)壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用下與氣(qi)流分離。負極(ji)由不同斷面(mian)形狀的(de)(de)金屬(shu)(shu)導(dao)(dao)線制成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同幾(ji)何形狀的(de)(de)金屬(shu)(shu)板制成(cheng)，叫集(ji)塵(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器的(de)(de)性能(neng)受粉(fen)塵(chen)性質(zhi)、設(she)備(bei)構造和(he)煙氣(qi)流速等三(san)個因素的(de)(de)影響。粉(fen)塵(chen)的(de)(de)比電(dian)(dian)(dian)阻(zu)是評價導(dao)(dao)電(dian)(dian)(dian)性的(de)(de)指標(biao)，它(ta)對除(chu)(chu)(chu)塵(chen)效率有(you)直接的(de)(de)影響。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保持在集(ji)塵(chen)電(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流。比電(dian)(dian)(dian)阻(zu)過高(gao)，到達集(ji)塵(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)壓梯(ti)度會(hui)產生(sheng)局部擊穿和(he)放(fang)電(dian)(dian)(dian)現象。這些情(qing)況(kuang)都會(hui)造成(cheng)除(chu)(chu)(chu)塵(chen)效率下降。

電(dian)除塵(chen)器的(de)基本原理(li)(li)是利(li)用電(dian)力捕集(ji)煙氣中(zhong)的(de)粉(fen)(fen)塵(chen)，主(zhu)要(yao)包括以下四個相互有關的(de)物理(li)(li)過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)(fen)塵(chen)的(de)捕集(ji)。
