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(shi)靜電(dian)(dian)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化法(fa)來收捕廢氣中的(de)粉塵(chen)，它的(de)凈(jing)化工(gong)作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)(he)沉淀兩個系(xi)(xi)統來完成(cheng)的(de)，當(dang)含塵(chen)氣體進人氣刺叭時(shi)，含塵(chen)氣體受到(dao)氣流分布板(ban)以及折流板(ban)的(de)調整后，使(shi)(shi)氣流能較(jiao)均勻地進人電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷面擴大(da)的(de)作(zuo)(zuo)用下(xia)(xia)，氣流速(su)度(du)迅(xun)速(su)降(jiang)低，其中有些較(jiao)重的(de)塵(chen)粒便失去速(su)度(du)而沉降(jiang)下(xia)(xia)來。進人電(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)氣體由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)氣體中存在(zai)(zai)(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與(yu)進人電(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)結合起來，使(shi)(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)作(zuo)(zuo)用下(xia)(xia)趨向本(ben)(ben)設(she)(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)(ben)設(she)(she)備(bei)采用負高(gao)壓(ya)制(zhi))和(he)(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積(ji)在(zai)(zai)(zai)相應的(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設(she)(she)備(bei)陰(yin)陽極(ji)(ji)(ji)振打系(xi)(xi)統的(de)振打，使(shi)(shi)沉積(ji)在(zai)(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)粉塵(chen)振落，進人集灰斗 通過(guo)排灰裝置放出，回收有物料，被)凈(jing)化的(de)氣體排入大(da)氣。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)工作原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場(chang)(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離(li)(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)(chang)作用下與氣(qi)流(liu)分離(li)(li)。負極(ji)由不(bu)同斷面形(xing)狀的(de)(de)(de)金屬導(dao)(dao)線制(zhi)成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不(bu)同幾(ji)何形(xing)狀的(de)(de)(de)金屬板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)性(xing)(xing)能受粉塵(chen)(chen)(chen)性(xing)(xing)質、設備構造和(he)(he)煙(yan)氣(qi)流(liu)速等(deng)三個因(yin)素的(de)(de)(de)影(ying)響(xiang)(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是(shi)評價導(dao)(dao)電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)效率有直接的(de)(de)(de)影(ying)響(xiang)(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)壓梯度會(hui)(hui)產生局部擊穿和(he)(he)放電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)(hui)造成除塵(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)器的基本原理是利用電(dian)(dian)(dian)力捕集(ji)(ji)煙氣中的粉塵(chen)，主要包括(kuo)以下四個相互有關的物(wu)理過程: (1) 氣體的電(dian)(dian)(dian)離。(2) 粉塵(chen)的荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)(dian)粉塵(chen)的捕集(ji)(ji)。
