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(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器是以(yi)靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)中(zhong)的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈化工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)(chen)淀(dian)兩個(ge)系統來(lai)完成的(de)(de)(de)，當含塵(chen)氣(qi)體進(jin)人氣(qi)刺叭(ba)時，含塵(chen)氣(qi)體受到氣(qi)流分布板(ban)以(yi)及折流板(ban)的(de)(de)(de)調整后(hou)，使氣(qi)流能較均勻地(di)進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫(heng)斷面擴(kuo)大的(de)(de)(de)作(zuo)用下，氣(qi)流速度迅速降(jiang)低，其中(zhong)有些較重(zhong)的(de)(de)(de)塵(chen)粒便失去速度而沉(chen)(chen)降(jiang)下來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)氣(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人高(gao)壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)體中(zhong)存在大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與(yu)進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)結合(he)起來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下趨(qu)向(xiang)本(ben)(ben)設(she)備(bei)陽極(ji)(正極(ji)、本(ben)(ben)設(she)備(bei)采用負高(gao)壓制)和陰(yin)極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別(bie)沉(chen)(chen)積(ji)在相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設(she)備(bei)陰(yin)陽極(ji)振打系統的(de)(de)(de)振打，使沉(chen)(chen)積(ji)在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉塵(chen)振落，進(jin)人集灰斗 通過排(pai)灰裝置放出(chu)，回收有物(wu)料，被)凈化的(de)(de)(de)氣(qi)體排(pai)入大氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)工作(zuo)原(yuan)理是利用高壓電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)粉塵(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與氣(qi)(qi)流(liu)分離。負極(ji)(ji)由不同斷面形狀的(de)(de)(de)金(jin)屬導線制成(cheng)(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形狀的(de)(de)(de)金(jin)屬板制成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)性(xing)能(neng)受(shou)粉塵(chen)性(xing)質(zhi)、設備構造(zao)和煙氣(qi)(qi)流(liu)速等三(san)個因(yin)素的(de)(de)(de)影響(xiang)。粉塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標(biao)，它對除塵(chen)效率有直接的(de)(de)(de)影響(xiang)。比電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)粒(li)難以保(bao)持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使其(qi)重(zhong)返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過高，到(dao)達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)產(chan)生(sheng)局部(bu)擊(ji)穿和放電(dian)(dian)(dian)(dian)現(xian)象。這些情況都(dou)會(hui)造(zao)成(cheng)(cheng)除塵(chen)效率下(xia)降(jiang)。

電(dian)(dian)(dian)除塵(chen)器的(de)基本(ben)原理是利用電(dian)(dian)(dian)力捕(bu)集(ji)煙氣中的(de)粉塵(chen)，主要包括以下(xia)四個相(xiang)互有關的(de)物理過(guo)程: (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉塵(chen)的(de)捕(bu)集(ji)。
