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)除塵器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收(shou)捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵，它的(de)(de)(de)(de)(de)(de)(de)凈(jing)化工作上(shang)要是依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極和(he)沉淀(dian)兩個系統(tong)來完(wan)成的(de)(de)(de)(de)(de)(de)(de)，當(dang)含塵氣(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含塵氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布(bu)板(ban)(ban)以及(ji)折流(liu)(liu)板(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)調(diao)整后(hou)，使(shi)(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷(duan)面擴(kuo)大(da)的(de)(de)(de)(de)(de)(de)(de)作用(yong)(yong)下，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其(qi)中有些較重的(de)(de)(de)(de)(de)(de)(de)塵粒便失去速度而沉降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)(de)含塵氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極通人(ren)(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵結合起來，使(shi)(shi)塵粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)(de)(de)作用(yong)(yong)下趨向(xiang)本(ben)設(she)備(bei)陽極(正極、本(ben)設(she)備(bei)采(cai)用(yong)(yong)負高(gao)壓制)和(he)陰(yin)(yin)極(負極) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積在(zai)相應的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)，通過設(she)備(bei)陰(yin)(yin)陽極振打(da)系統(tong)的(de)(de)(de)(de)(de)(de)(de)振打(da)，使(shi)(shi)沉積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵振落，進(jin)(jin)人(ren)(ren)集灰(hui)(hui)斗 通過排灰(hui)(hui)裝置放出，回收(shou)有物料，被)凈(jing)化的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)工作(zuo)原(yuan)理是(shi)利用高壓電(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)發生電(dian)(dian)離，氣(qi)流中的(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分離。負極由不同斷面形狀的(de)金(jin)屬導線制成，叫放(fang)電(dian)(dian)電(dian)(dian)極。正極由不同幾何形狀的(de)金(jin)屬板制成，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極。靜(jing)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造和(he)煙(yan)氣(qi)流速(su)等三個因素的(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)性(xing)的(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直接(jie)的(de)影響。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極上，致使(shi)其重返氣(qi)流。比(bi)電(dian)(dian)阻過高，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)(chen)層(ceng)之(zhi)間形成電(dian)(dian)壓梯(ti)度會(hui)產生局(ju)部擊穿和(he)放(fang)電(dian)(dian)現象。這(zhe)些情況(kuang)都會(hui)造成除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)除塵器的(de)(de)(de)基本原理是利(li)用電(dian)(dian)(dian)力捕集(ji)煙氣中的(de)(de)(de)粉塵，主要(yao)包(bao)括以下四(si)個相互有關的(de)(de)(de)物理過程: (1) 氣體的(de)(de)(de)電(dian)(dian)(dian)離(li)。(2) 粉塵的(de)(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉塵的(de)(de)(de)捕集(ji)。
