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)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕(bu)廢氣(qi)中的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈化工作(zuo)(zuo)上(shang)(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩個系統(tong)來(lai)完成的(de)(de)(de)，當含塵(chen)(chen)氣(qi)體(ti)進(jin)人(ren)(ren)(ren)氣(qi)刺叭時，含塵(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)(liu)分布(bu)板以及折流(liu)(liu)(liu)板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)(liu)(liu)能較(jiao)均勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面(mian)擴大(da)的(de)(de)(de)作(zuo)(zuo)用下，氣(qi)流(liu)(liu)(liu)速(su)度(du)迅速(su)降低，其中有些較(jiao)重的(de)(de)(de)塵(chen)(chen)粒便失去速(su)度(du)而沉降下來(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)(ren)(ren)高壓(ya)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)體(ti)中存在(zai)大(da)量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)(zuo)用下趨向(xiang)本設(she)(she)備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)(she)備采用負高壓(ya)制)和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)(shang)，通(tong)過(guo)設(she)(she)備陰陽極(ji)(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)(shang)的(de)(de)(de)粉塵(chen)(chen)振落(luo)，進(jin)人(ren)(ren)(ren)集灰(hui)斗 通(tong)過(guo)排灰(hui)裝置(zhi)放(fang)出，回收有物料，被(bei))凈化的(de)(de)(de)氣(qi)體(ti)排入(ru)大(da)氣(qi)。

工作原理(li)

靜電(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)工作原(yuan)理是利用高(gao)壓電(dian)場使煙(yan)氣(qi)發生電(dian)離，氣(qi)流中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)在電(dian)場作用下與氣(qi)流分離。負極(ji)(ji)(ji)(ji)(ji)由不同(tong)斷面形狀的(de)(de)金(jin)屬(shu)導(dao)線制(zhi)成(cheng)，叫放電(dian)電(dian)極(ji)(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)(ji)由不同(tong)幾何形狀的(de)(de)金(jin)屬(shu)板(ban)制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)(ji)(ji)(ji)。靜電(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)性能(neng)受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和煙(yan)氣(qi)流速(su)等三個因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)阻(zu)是評價導(dao)電(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效率有直接(jie)的(de)(de)影(ying)響。比電(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以保持(chi)在集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)(ji)(ji)(ji)上，致使其重返氣(qi)流。比電(dian)阻(zu)過(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)(ji)(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)荷(he)不易放出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)壓梯(ti)度(du)會(hui)產生局部擊穿和放電(dian)現象。這些情況(kuang)都會(hui)造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵器的基本原理是(shi)利用(yong)電(dian)(dian)(dian)力捕集煙氣中的粉(fen)(fen)塵，主要包括以下四個相互有關的物(wu)理過程: (1) 氣體(ti)的電(dian)(dian)(dian)離(li)。(2) 粉(fen)(fen)塵的荷(he)(he)電(dian)(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)(dian)粉(fen)(fen)塵向(xiang)電(dian)(dian)(dian)極移動。(4) 荷(he)(he)電(dian)(dian)(dian)粉(fen)(fen)塵的捕集。
