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(wo)式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)(de)(de)凈化工作(zuo)(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉淀兩個系統來完成的(de)(de)(de)(de)(de)(de)，當(dang)含(han)塵(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)(jin)人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分(fen)布板以及折流(liu)(liu)板的(de)(de)(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)流(liu)(liu)能較(jiao)均勻地進(jin)(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)(zuo)用下，氣(qi)(qi)流(liu)(liu)速(su)度迅速(su)降(jiang)低，其(qi)中有(you)些較(jiao)重(zhong)的(de)(de)(de)(de)(de)(de)塵(chen)粒便(bian)失去速(su)度而沉降(jiang)下來。進(jin)(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人(ren)(ren)(ren)高(gao)壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)(dian)子和離子與進(jin)(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)結合(he)起來，使(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)(zuo)用下趨向本設(she)備陽極(ji)(正(zheng)極(ji)、本設(she)備采用負高(gao)壓(ya)制)和陰(yin)(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分(fen)別(bie)沉積在(zai)相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設(she)備陰(yin)(yin)陽極(ji)振(zhen)打系統的(de)(de)(de)(de)(de)(de)振(zhen)打，使(shi)沉積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)(de)粉塵(chen)振(zhen)落(luo)，進(jin)(jin)(jin)人(ren)(ren)(ren)集灰斗 通(tong)過排灰裝置放出，回收(shou)有(you)物料，被(bei))凈化的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)工(gong)作(zuo)原理是利用高壓電(dian)(dian)(dian)場使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)(de)粉塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)流(liu)(liu)分離。負(fu)極(ji)(ji)由(you)不同斷面(mian)形狀的(de)(de)(de)金(jin)屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀的(de)(de)(de)金(jin)屬板制成(cheng)，叫(jiao)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)性(xing)(xing)能受粉塵(chen)性(xing)(xing)質、設備(bei)構造和煙(yan)氣(qi)流(liu)(liu)速(su)等三個因(yin)素的(de)(de)(de)影響。粉塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性(xing)(xing)的(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)效率有(you)直(zhi)接的(de)(de)(de)影響。比電(dian)(dian)(dian)阻過低，塵(chen)粒難以保持在集塵(chen)電(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重(zhong)返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)阻過高，到達集塵(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)荷不易放出，在塵(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯度(du)會產生(sheng)局部擊(ji)穿(chuan)和放電(dian)(dian)(dian)現象。這(zhe)些情(qing)況都會造成(cheng)除(chu)塵(chen)效率下(xia)降。

電除塵(chen)器的基(ji)本原理(li)是利用電力(li)捕集煙氣中(zhong)的粉塵(chen)，主要(yao)包括以(yi)下四個相互(hu)有(you)關的物理(li)過程: (1) 氣體(ti)(ti)的電離。(2) 粉塵(chen)的荷(he)電。(3) 荷(he)電粉塵(chen)向電極移(yi)動。(4) 荷(he)電粉塵(chen)的捕集。
