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)除塵(chen)(chen)器是以靜(jing)(jing)電(dian)(dian)凈化(hua)法來收(shou)捕廢氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)粉塵(chen)(chen)，它的(de)凈化(hua)工作上要(yao)是依靠電(dian)(dian)暈(yun)極(ji)(ji)和(he)(he)沉淀兩個系(xi)統(tong)來完成的(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)分(fen)布板(ban)以及折流(liu)板(ban)的(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均(jun)勻地進(jin)(jin)(jin)人(ren)電(dian)(dian)場。在(zai)橫斷面擴大的(de)作用下，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降低(di)，其中(zhong)(zhong)有(you)些較(jiao)重的(de)塵(chen)(chen)粒便失去速度而沉降下來。進(jin)(jin)(jin)人(ren)電(dian)(dian)場的(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由(you)于(yu)電(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)高壓(ya)直(zhi)流(liu)電(dian)(dian)，則(ze)在(zai)電(dian)(dian)暈(yun)極(ji)(ji)附(fu)近產生電(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后(hou)的(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)大量(liang)的(de)電(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這些電(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與進(jin)(jin)(jin)人(ren)電(dian)(dian)場的(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶(dai)(dai)電(dian)(dian)，帶(dai)(dai)電(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)場力的(de)作用下趨向本設(she)(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)(she)備采用負高壓(ya)制)和(he)(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)子(zi)分(fen)別沉積(ji)在(zai)相應的(de)電(dian)(dian)極(ji)(ji)上，通(tong)過(guo)設(she)(she)備陰陽(yang)極(ji)(ji)振打(da)系(xi)統(tong)的(de)振打(da)，使(shi)沉積(ji)在(zai)陰陽(yang)電(dian)(dian)極(ji)(ji)上的(de)粉塵(chen)(chen)振落，進(jin)(jin)(jin)人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放出，回(hui)收(shou)有(you)物料，被(bei))凈化(hua)的(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的工作(zuo)原(yuan)理是(shi)利(li)用(yong)高壓電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)離(li)(li)，氣(qi)流中的粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用(yong)下(xia)與氣(qi)流分離(li)(li)。負極(ji)(ji)由不同(tong)斷面形(xing)狀(zhuang)的金屬導(dao)線(xian)制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不同(tong)幾何形(xing)狀(zhuang)的金屬板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和(he)煙(yan)氣(qi)流速(su)等三個(ge)因(yin)素的影響。粉塵(chen)(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)阻是(shi)評價(jia)導(dao)電(dian)(dian)(dian)性(xing)的指標，它對除塵(chen)(chen)(chen)(chen)效率有直(zhi)接的影響。比(bi)電(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣(qi)流。比(bi)電(dian)(dian)(dian)阻過(guo)高，到(dao)達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局部(bu)擊(ji)穿和(he)放(fang)電(dian)(dian)(dian)現(xian)象。這些情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)除塵(chen)器的基(ji)本原理(li)是利(li)用電(dian)力捕集(ji)煙氣中的粉塵(chen)，主要包括以(yi)下四個(ge)相互有關的物(wu)理(li)過程: (1) 氣體的電(dian)離。(2) 粉塵(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)的捕集(ji)。
