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)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)(lai)收(shou)捕(bu)廢氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)(de)凈(jing)化(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和(he)沉(chen)淀兩個系(xi)統來(lai)(lai)(lai)完(wan)成的(de)(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流分(fen)布板(ban)以及(ji)折流板(ban)的(de)(de)(de)(de)調整后，使氣(qi)(qi)流能較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷(duan)面擴大的(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)流速(su)度迅速(su)降低，其(qi)中(zhong)(zhong)有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失(shi)去速(su)度而沉(chen)降下來(lai)(lai)(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通人(ren)高壓直流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)暈現(xian)象(xiang)，使氣(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)體中(zhong)(zhong)存在(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)子和(he)離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起(qi)來(lai)(lai)(lai)，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用下趨向本設(she)備陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備采用負高壓制)和(he)陰(yin)(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子分(fen)別沉(chen)積在(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通過設(she)備陰(yin)(yin)陽極(ji)(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)振(zhen)打，使沉(chen)積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通過排灰裝置放出(chu)，回收(shou)有物料(liao)，被)凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)(qi)體排入大氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)(de)(de)工(gong)作(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣(qi)(qi)流(liu)分離。負(fu)極(ji)由不(bu)同(tong)斷面形狀的(de)(de)(de)(de)(de)金屬(shu)導線制成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形狀的(de)(de)(de)(de)(de)金屬(shu)板制成，叫(jiao)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設備構造和煙(yan)氣(qi)(qi)流(liu)速等三個因(yin)素的(de)(de)(de)(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指標(biao)，它對(dui)除(chu)塵(chen)效率有直接(jie)的(de)(de)(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)粒(li)(li)難以(yi)保持在集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)塵(chen)粒(li)(li)電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)層之間(jian)形成電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度(du)會(hui)產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成除(chu)塵(chen)效率下降。

電(dian)(dian)除塵器的(de)(de)基本原理是利用電(dian)(dian)力捕集煙氣(qi)中的(de)(de)粉(fen)(fen)塵，主要包括以下四個相(xiang)互(hu)有關的(de)(de)物理過程: (1) 氣(qi)體的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵的(de)(de)荷(he)(he)(he)電(dian)(dian)。(3) 荷(he)(he)(he)電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移(yi)動(dong)。(4) 荷(he)(he)(he)電(dian)(dian)粉(fen)(fen)塵的(de)(de)捕集。
