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(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)(hua)法(fa)來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)(hua)工作上要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)淀兩(liang)個系(xi)統來完成的(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體進(jin)(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體受到(dao)氣(qi)(qi)(qi)(qi)流(liu)(liu)分(fen)布(bu)板以及折流(liu)(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)流(liu)(liu)能較(jiao)均勻地進(jin)(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷(duan)面擴(kuo)大(da)(da)(da)的(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流(liu)(liu)速(su)(su)度迅速(su)(su)降(jiang)低，其(qi)中(zhong)有些較(jiao)重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速(su)(su)度而沉(chen)降(jiang)下來。進(jin)(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)高壓(ya)(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在(zai)(zai)大(da)(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下趨向(xiang)本設(she)備(bei)陽(yang)(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采用負(fu)(fu)高壓(ya)(ya)制)和(he)陰極(ji)(ji)(ji)(負(fu)(fu)極(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)子(zi)分(fen)別(bie)沉(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過設(she)備(bei)陰陽(yang)(yang)極(ji)(ji)(ji)振打(da)系(xi)統的(de)(de)(de)振打(da)，使(shi)沉(chen)積在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落，進(jin)(jin)(jin)人(ren)集灰斗 通(tong)過排灰裝置放(fang)出(chu)，回收有物料(liao)，被)凈(jing)(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入大(da)(da)(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工作原理是利用(yong)高壓電(dian)(dian)場使煙氣(qi)發生電(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用(yong)下與氣(qi)流(liu)(liu)分離。負極由不(bu)(bu)同(tong)斷面形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)導線制成，叫放(fang)(fang)電(dian)(dian)電(dian)(dian)極。正極由不(bu)(bu)同(tong)幾何形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)板制成，叫集塵(chen)(chen)(chen)電(dian)(dian)極。靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性能受(shou)粉塵(chen)(chen)(chen)性質、設備(bei)構造和煙氣(qi)流(liu)(liu)速(su)等(deng)三個因素的(de)(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)性的(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)效(xiao)率(lv)有直接的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)極上，致使其重返氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)電(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不(bu)(bu)易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)壓梯度會(hui)產生局(ju)部擊穿和放(fang)(fang)電(dian)(dian)現象。這些情(qing)況都會(hui)造成除塵(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)除塵器的(de)(de)基本原理是利用電(dian)力捕集(ji)煙(yan)氣(qi)中的(de)(de)粉(fen)塵，主(zhu)要包括以下四(si)個相(xiang)互有關的(de)(de)物理過程: (1) 氣(qi)體(ti)的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向(xiang)電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)塵的(de)(de)捕集(ji)。
