XWD型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)除塵器(qi)是以靜(jing)電(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉塵，它的(de)(de)(de)凈化(hua)工作上(shang)要(yao)是依靠電(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系統來(lai)完成的(de)(de)(de)，當(dang)含塵氣(qi)(qi)(qi)體進人(ren)(ren)氣(qi)(qi)(qi)刺(ci)叭(ba)時，含塵氣(qi)(qi)(qi)體受到(dao)氣(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)流能較(jiao)均(jun)勻地進人(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴大的(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)流速(su)(su)度(du)迅(xun)速(su)(su)降低(di)，其中有些較(jiao)重的(de)(de)(de)塵粒便失去(qu)速(su)(su)度(du)而沉降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高(gao)壓直(zhi)流電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)(qi)體中存在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這些電(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與進人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵結合起來(lai)，使(shi)塵粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵粒在(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下趨(qu)向本(ben)設(she)備陽(yang)極(ji)(正極(ji)、本(ben)設(she)備采(cai)用(yong)負(fu)高(gao)壓制)和(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)(zi)分(fen)別(bie)沉積(ji)在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通過設(she)備陰(yin)陽(yang)極(ji)振打(da)系統的(de)(de)(de)振打(da)，使(shi)沉積(ji)在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉塵振落(luo)，進人(ren)(ren)集(ji)灰(hui)斗 通過排(pai)灰(hui)裝置放出(chu)，回收有物料(liao)，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)體排(pai)入大氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的工作原理是利用高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)分離(li)。負極(ji)(ji)(ji)由(you)不(bu)(bu)同斷面形(xing)狀的金屬導(dao)(dao)線制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不(bu)(bu)同幾何形(xing)狀的金屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設(she)備構造和煙氣(qi)流(liu)速等三個因素的影響(xiang)。粉(fen)塵(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評(ping)價導(dao)(dao)電(dian)(dian)(dian)(dian)性(xing)的指標，它對(dui)除塵(chen)(chen)效(xiao)率有直接(jie)的影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)粒難(nan)以保持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在塵(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情況都會造成(cheng)除塵(chen)(chen)效(xiao)率下降。

電(dian)除塵器的(de)基本(ben)原(yuan)理是利用電(dian)力捕集(ji)煙(yan)氣(qi)中的(de)粉(fen)塵，主要包(bao)括以下四(si)個相互有(you)關的(de)物理過程: (1) 氣(qi)體(ti)的(de)電(dian)離。(2) 粉(fen)塵的(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)塵的(de)捕集(ji)。
