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)器(qi)是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)凈化工作(zuo)(zuo)上(shang)(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩個系(xi)統來(lai)(lai)(lai)完成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)(liu)能(neng)較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)作(zuo)(zuo)用下，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其(qi)中有些較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速度而沉降下來(lai)(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)中存在(zai)大(da)量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)(lai)(lai)，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)作(zuo)(zuo)用下趨向本設備(bei)(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)(bei)采用負高壓制)和(he)陰(yin)(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通過(guo)設備(bei)(bei)陰(yin)(yin)陽(yang)極(ji)(ji)振(zhen)打(da)系(xi)統的(de)(de)(de)振(zhen)打(da)，使沉積在(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)(ren)集(ji)灰斗 通過(guo)排(pai)灰裝置放出，回收有物料，被)凈化的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理(li)

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)(de)工作原理(li)是利用高壓電(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣發(fa)生(sheng)(sheng)電(dian)(dian)(dian)離，氣流(liu)中(zhong)的(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場(chang)作用下與氣流(liu)分離。負極(ji)由不同(tong)(tong)斷面形(xing)狀的(de)(de)(de)(de)(de)金屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同(tong)(tong)幾何(he)形(xing)狀的(de)(de)(de)(de)(de)金屬板制成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)(de)性能受粉(fen)(fen)塵(chen)(chen)性質(zhi)、設備(bei)構造(zao)和煙(yan)氣流(liu)速等三個因(yin)素的(de)(de)(de)(de)(de)影響(xiang)。粉(fen)(fen)塵(chen)(chen)的(de)(de)(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指(zhi)標，它對除(chu)(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)(de)(de)影響(xiang)。比(bi)(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難以保持在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在(zai)(zai)塵(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度(du)會(hui)產生(sheng)(sheng)局(ju)部(bu)擊穿和放電(dian)(dian)(dian)現象(xiang)。這(zhe)些情況(kuang)都會(hui)造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)(dian)除(chu)塵器的基本原理是利用(yong)電(dian)(dian)(dian)(dian)力捕集(ji)(ji)煙氣中(zhong)的粉(fen)塵，主要(yao)包(bao)括以下四個相互有關的物理過(guo)程: (1) 氣體的電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵的荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵的捕集(ji)(ji)。
