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。

臥式靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)是以(yi)靜電(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈化(hua)工作上(shang)要是依靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉(chen)(chen)淀兩個系統來(lai)完成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受(shou)到氣(qi)(qi)(qi)(qi)流(liu)分布(bu)板以(yi)及折流(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)場(chang)。在橫斷面擴大(da)的(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)速度迅(xun)速降低，其中有些較(jiao)重(zhong)的(de)(de)(de)塵(chen)(chen)粒(li)便失(shi)去速度而沉(chen)(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體中存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起(qi)來(lai)，使(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下趨向本設(she)備陽(yang)(yang)極(ji)(正極(ji)、本設(she)備采用(yong)負高(gao)壓制(zhi))和(he)陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設(she)備陰(yin)陽(yang)(yang)極(ji)振打系統的(de)(de)(de)振打，使(shi)沉(chen)(chen)積在陰(yin)陽(yang)(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)集灰斗 通過(guo)排(pai)灰裝置(zhi)放出，回收有物(wu)料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體排(pai)入大(da)氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原理(li)是利用高壓電(dian)(dian)(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下與(yu)氣(qi)流(liu)分離。負極(ji)(ji)由不同斷(duan)面形狀的(de)(de)金屬導線制成(cheng)(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何(he)形狀的(de)(de)金屬板制成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)性質、設備(bei)構造和(he)煙氣(qi)流(liu)速等三個因素的(de)(de)影(ying)(ying)響。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)影(ying)(ying)響。比電(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣(qi)流(liu)。比電(dian)(dian)(dian)阻(zu)過高，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易(yi)放出，在(zai)塵(chen)(chen)層(ceng)之間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)壓梯(ti)度(du)會產生(sheng)局部擊穿和(he)放電(dian)(dian)(dian)現(xian)象。這些(xie)情況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)效(xiao)率下降(jiang)。

電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)基本原理(li)是利用電(dian)(dian)力(li)捕(bu)集煙氣中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，主(zhu)要包括以(yi)下(xia)四個相互有關的(de)(de)物理(li)過程: (1) 氣體(ti)的(de)(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)(chen)(chen)(chen)(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)捕(bu)集。
