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)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法(fa)來收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)凈化(hua)(hua)工(gong)作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極和沉(chen)淀兩(liang)個系(xi)統來完成的(de)(de)(de)(de)，當(dang)含塵(chen)氣(qi)(qi)(qi)體進人氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流(liu)(liu)(liu)分布板以(yi)及(ji)折(zhe)流(liu)(liu)(liu)板的(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)(liu)能較(jiao)均勻地進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面(mian)擴大的(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度(du)迅速(su)降(jiang)低，其中有些較(jiao)重的(de)(de)(de)(de)塵(chen)粒(li)便失去速(su)度(du)而沉(chen)降(jiang)下(xia)來。進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極通人高壓直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈極附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)體中存在大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)結(jie)合起來，使(shi)塵(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用下(xia)趨向本設(she)備陽(yang)極(正極、本設(she)備采(cai)用負(fu)高壓制(zhi))和陰(yin)(yin)極(負(fu)極) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別(bie)沉(chen)積(ji)在相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極上，通過設(she)備陰(yin)(yin)陽(yang)極振(zhen)打(da)系(xi)統的(de)(de)(de)(de)振(zhen)打(da)，使(shi)沉(chen)積(ji)在陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)(de)粉塵(chen)振(zhen)落，進人集(ji)灰斗 通過排灰裝置(zhi)放出，回(hui)收(shou)有物料，被)凈化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵器的(de)工作原理(li)是利用(yong)高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的(de)粉(fen)(fen)塵荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)流(liu)分離(li)。負極(ji)由不(bu)同(tong)斷面形(xing)狀的(de)金屬導(dao)線制(zhi)成，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形(xing)狀的(de)金屬板制(zhi)成，叫集塵電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵器的(de)性能受粉(fen)(fen)塵性質、設備構造和(he)煙氣(qi)流(liu)速等三(san)個因素的(de)影響。粉(fen)(fen)塵的(de)比(bi)電(dian)(dian)(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)(dian)(dian)性的(de)指(zhi)標，它對除(chu)塵效率(lv)有(you)直接的(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵粒難以(yi)保持在集塵電(dian)(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達集塵電(dian)(dian)(dian)(dian)極(ji)的(de)塵粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放(fang)出，在塵層之間(jian)形(xing)成電(dian)(dian)(dian)(dian)壓梯度會產(chan)生(sheng)局(ju)部擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)現(xian)象。這些情(qing)況都(dou)會造成除(chu)塵效率(lv)下降。

電(dian)(dian)除塵器的基本原(yuan)理(li)是利用電(dian)(dian)力捕(bu)集(ji)煙氣中的粉(fen)(fen)塵，主(zhu)要包(bao)括以(yi)下四個相互有關的物理(li)過程: (1) 氣體的電(dian)(dian)離(li)。(2) 粉(fen)(fen)塵的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉(fen)(fen)塵的捕(bu)集(ji)。
