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(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化法來收(shou)捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)(jing)化工(gong)作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉淀(dian)兩個系統來完成的(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分(fen)布板以(yi)(yi)及折流板的(de)(de)調整后，使(shi)氣(qi)(qi)流能較(jiao)均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴(kuo)大的(de)(de)作用(yong)(yong)下，氣(qi)(qi)流速度(du)迅(xun)速降(jiang)低(di)，其中有些較(jiao)重的(de)(de)塵(chen)(chen)粒便失(shi)去速度(du)而沉降(jiang)下來。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人高壓(ya)直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)中存在(zai)(zai)大量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結(jie)合起來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)作用(yong)(yong)下趨向本設備陽極(ji)(正極(ji)、本設備采用(yong)(yong)負(fu)高壓(ya)制)和陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積(ji)在(zai)(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設備陰(yin)陽極(ji)振(zhen)(zhen)打系統的(de)(de)振(zhen)(zhen)打，使(shi)沉積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉塵(chen)(chen)振(zhen)(zhen)落，進(jin)人集灰斗 通過排灰裝置(zhi)放(fang)出(chu)，回(hui)收(shou)有物料，被(bei))凈(jing)(jing)化的(de)(de)氣(qi)(qi)體(ti)排入(ru)大氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原理是利(li)用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)粉塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流(liu)(liu)分離。負(fu)極(ji)由不同(tong)斷面(mian)形狀的(de)(de)金(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾(ji)何形狀的(de)(de)金(jin)屬板(ban)制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能(neng)受粉塵(chen)(chen)性質(zhi)、設(she)備構(gou)造和(he)煙氣(qi)流(liu)(liu)速(su)等三個因素的(de)(de)影(ying)(ying)響。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)效(xiao)(xiao)率有(you)直接的(de)(de)影(ying)(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返(fan)氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)(he)不易放出，在塵(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生局(ju)部(bu)擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都(dou)會(hui)造成(cheng)除(chu)塵(chen)(chen)效(xiao)(xiao)率下(xia)降。

電(dian)(dian)除塵(chen)器(qi)的(de)(de)基本原理是利用(yong)電(dian)(dian)力(li)捕(bu)集(ji)煙(yan)氣中的(de)(de)粉塵(chen)，主要包括以下四個(ge)相互有關的(de)(de)物理過程(cheng): (1) 氣體的(de)(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵(chen)的(de)(de)捕(bu)集(ji)。
