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)(chen)(chen)(chen)器(qi)是以靜電(dian)(dian)(dian)(dian)凈化法(fa)來收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)凈化工作(zuo)上(shang)要(yao)是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)(chen)淀兩(liang)個(ge)系統來完成的(de)(de)，當(dang)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分布板以及折流(liu)板的(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)能較均勻地(di)進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷面(mian)擴大(da)的(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流(liu)速度(du)迅速降低，其中(zhong)有些較重(zhong)的(de)(de)塵(chen)(chen)(chen)(chen)粒便(bian)失去速度(du)而沉(chen)(chen)降下(xia)來。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存在大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結(jie)合(he)起來，使塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下(xia)趨(qu)向(xiang)本設備陽極(ji)(ji)(正極(ji)(ji)、本設備采用負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)(chen)積在相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備陰陽極(ji)(ji)振(zhen)打系統的(de)(de)振(zhen)打，使沉(chen)(chen)積在陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)(ren)(ren)集(ji)灰(hui)斗 通過排灰(hui)裝置放出，回收有物料，被)凈化的(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)(de)(de)工(gong)作原理(li)是利用高壓電(dian)(dian)場使(shi)煙氣(qi)(qi)發生(sheng)電(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用下與氣(qi)(qi)流(liu)分(fen)離(li)。負(fu)極(ji)由(you)不同斷面形(xing)狀的(de)(de)(de)(de)(de)(de)金屬導線制(zhi)成，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形(xing)狀的(de)(de)(de)(de)(de)(de)金屬板制(zhi)成，叫(jiao)集塵(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)(de)(de)性能受(shou)粉(fen)塵(chen)(chen)性質、設(she)備構(gou)造和煙氣(qi)(qi)流(liu)速等三個因素(su)的(de)(de)(de)(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)(de)(de)比電(dian)(dian)阻是評(ping)價導電(dian)(dian)性的(de)(de)(de)(de)(de)(de)指標，它(ta)對除塵(chen)(chen)效率(lv)有直接的(de)(de)(de)(de)(de)(de)影響(xiang)。比電(dian)(dian)阻過低，塵(chen)(chen)粒難以(yi)保持在(zai)集塵(chen)(chen)電(dian)(dian)極(ji)上，致(zhi)使(shi)其(qi)重返氣(qi)(qi)流(liu)。比電(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)層之間(jian)形(xing)成電(dian)(dian)壓梯度會產生(sheng)局(ju)部擊穿(chuan)和放電(dian)(dian)現象。這(zhe)些(xie)情況都會造成除塵(chen)(chen)效率(lv)下降(jiang)。

電(dian)(dian)除塵(chen)(chen)(chen)器的(de)基(ji)本原理是利用電(dian)(dian)力捕(bu)集煙氣中的(de)粉塵(chen)(chen)(chen)，主(zhu)要包括以(yi)下四(si)個(ge)相互有關(guan)的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵(chen)(chen)(chen)的(de)捕(bu)集。
