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)器是以靜電(dian)(dian)(dian)凈化法來收(shou)捕廢(fei)氣(qi)中(zhong)的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈化工作(zuo)(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩個系統來完成(cheng)的(de)(de)，當(dang)含(han)塵(chen)氣(qi)體(ti)進人氣(qi)刺(ci)叭時，含(han)塵(chen)氣(qi)體(ti)受到氣(qi)流分(fen)布板以及(ji)折流板的(de)(de)調整后，使(shi)氣(qi)流能較均勻地進人電(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴大的(de)(de)作(zuo)(zuo)用(yong)下，氣(qi)流速度迅速降低，其(qi)中(zhong)有(you)些(xie)較重的(de)(de)塵(chen)粒(li)便失去速度而沉降下來。進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)含(han)塵(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)通人高壓(ya)(ya)直(zhi)流電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極(ji)附(fu)近產生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)體(ti)中(zhong)存(cun)在大量的(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)塵(chen)結合起來，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作(zuo)(zuo)用(yong)下趨向本(ben)設備陽(yang)(yang)極(ji)(正極(ji)、本(ben)設備采(cai)用(yong)負(fu)高壓(ya)(ya)制)和(he)陰極(ji)(負(fu)極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子(zi)分(fen)別(bie)沉積在相應的(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設備陰陽(yang)(yang)極(ji)振打系統的(de)(de)振打，使(shi)沉積在陰陽(yang)(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉(fen)塵(chen)振落，進人集灰(hui)斗 通過(guo)排(pai)(pai)灰(hui)裝置放出，回收(shou)有(you)物料，被)凈化的(de)(de)氣(qi)體(ti)排(pai)(pai)入大氣(qi)。

工作原理

靜電(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作原理是利用高壓電(dian)場使煙(yan)氣(qi)發生電(dian)離(li)，氣(qi)流(liu)(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)在(zai)電(dian)場作用下(xia)與氣(qi)流(liu)(liu)分離(li)。負極(ji)由(you)不同(tong)斷(duan)面形狀(zhuang)(zhuang)的(de)(de)金(jin)屬(shu)導線制成(cheng)(cheng)，叫放(fang)電(dian)電(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形狀(zhuang)(zhuang)的(de)(de)金(jin)屬(shu)板制成(cheng)(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)。靜電(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)流(liu)(liu)速等(deng)三個因素(su)的(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)阻(zu)是評價導電(dian)性(xing)的(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響(xiang)。比電(dian)阻(zu)過低，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)極(ji)上，致使其重返氣(qi)流(liu)(liu)。比電(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒電(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)(chen)層之間(jian)形成(cheng)(cheng)電(dian)壓梯度會(hui)產(chan)生局部擊穿和放(fang)電(dian)現象。這些情況(kuang)都會(hui)造成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)除塵(chen)器的基本原理是(shi)利(li)用(yong)電(dian)力(li)捕(bu)集煙氣中的粉(fen)塵(chen)，主要(yao)包括(kuo)以下四個相互(hu)有關的物理過程(cheng): (1) 氣體的電(dian)離。(2) 粉(fen)塵(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向(xiang)電(dian)極移動(dong)。(4) 荷(he)電(dian)粉(fen)塵(chen)的捕(bu)集。
