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)除塵(chen)(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈化法來(lai)收(shou)捕(bu)廢氣(qi)中的(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)凈化工(gong)作(zuo)上要是(shi)依(yi)靠電(dian)(dian)(dian)暈極(ji)和(he)(he)沉(chen)淀兩(liang)個(ge)系統來(lai)完成的(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)進(jin)人(ren)(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分布板(ban)以及(ji)折流(liu)(liu)板(ban)的(de)(de)調整(zheng)后，使氣(qi)流(liu)(liu)能較均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫斷面(mian)擴大(da)的(de)(de)作(zuo)用下(xia)(xia)，氣(qi)流(liu)(liu)速(su)度迅速(su)降低，其中有(you)些較重的(de)(de)塵(chen)(chen)(chen)(chen)粒便失去(qu)速(su)度而沉(chen)降下(xia)(xia)來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)通(tong)人(ren)(ren)高(gao)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)暈現(xian)象(xiang)，使氣(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)體(ti)中存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下(xia)(xia)趨向本設備陽(yang)極(ji)(正極(ji)、本設備采(cai)用負(fu)高(gao)壓制)和(he)(he)陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分別(bie)沉(chen)積(ji)(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設備陰陽(yang)極(ji)振打(da)系統的(de)(de)振打(da)，使沉(chen)積(ji)(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)上的(de)(de)粉塵(chen)(chen)(chen)(chen)振落(luo)，進(jin)人(ren)(ren)集灰斗 通(tong)過(guo)排灰裝(zhuang)置放出，回收(shou)有(you)物料，被(bei))凈化的(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作(zuo)用下與(yu)氣(qi)流(liu)分離。負極(ji)(ji)(ji)由不同(tong)斷面形狀(zhuang)的(de)(de)(de)金屬導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同(tong)幾何形狀(zhuang)的(de)(de)(de)金屬板(ban)制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)性能(neng)受(shou)粉塵(chen)(chen)性質、設備構(gou)造和(he)煙(yan)氣(qi)流(liu)速等三個因素的(de)(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對(dui)除(chu)塵(chen)(chen)效率有(you)直接(jie)的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒(li)難以保(bao)持在(zai)(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)上，致使(shi)其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過(guo)高(gao)，到達(da)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在(zai)(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯(ti)度會(hui)產生局部擊穿和(he)放電(dian)(dian)(dian)現象。這些情況都會(hui)造成除(chu)塵(chen)(chen)效率下降。

電除(chu)塵(chen)器的(de)基(ji)本原理是(shi)利用電力捕(bu)(bu)集煙氣中(zhong)的(de)粉塵(chen)，主要包括以下四個(ge)相(xiang)互(hu)有關(guan)的(de)物理過程: (1) 氣體(ti)(ti)的(de)電離(li)。(2) 粉塵(chen)的(de)荷(he)電。(3) 荷(he)電粉塵(chen)向(xiang)電極移動。(4) 荷(he)電粉塵(chen)的(de)捕(bu)(bu)集。
