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。

工作原理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作(zuo)(zuo)原(yuan)理是利用高(gao)壓(ya)電(dian)(dian)場(chang)使(shi)煙氣(qi)發生(sheng)(sheng)電(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作(zuo)(zuo)用下(xia)與(yu)氣(qi)流(liu)分離。負極(ji)由(you)不同(tong)斷面形狀的(de)(de)金(jin)屬導(dao)線制成(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形狀的(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能受(shou)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)性質(zhi)、設備(bei)構造和煙氣(qi)流(liu)速等三個因素的(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻(zu)是評價(jia)導(dao)電(dian)(dian)性的(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣(qi)流(liu)。比(bi)電(dian)(dian)阻(zu)過高(gao)，到達(da)集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓(ya)梯度(du)會(hui)產生(sheng)(sheng)局部(bu)擊穿和放電(dian)(dian)現象。這些情況(kuang)都會(hui)造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)(chen)效率下(xia)降(jiang)。

電除塵器的(de)(de)(de)基本原(yuan)理是利用電力捕(bu)集(ji)煙氣中(zhong)的(de)(de)(de)粉(fen)(fen)(fen)塵，主(zhu)要包括(kuo)以下(xia)四個(ge)相互(hu)有關的(de)(de)(de)物理過(guo)程: (1) 氣體的(de)(de)(de)電離。(2) 粉(fen)(fen)(fen)塵的(de)(de)(de)荷電。(3) 荷電粉(fen)(fen)(fen)塵向電極(ji)移動。(4) 荷電粉(fen)(fen)(fen)塵的(de)(de)(de)捕(bu)集(ji)。
