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)(dian)(dian)(dian)除塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化法來(lai)收(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)粉(fen)塵(chen),它的(de)(de)(de)(de)(de)凈(jing)(jing)化工作(zuo)上要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉(chen)(chen)(chen)淀兩個(ge)系統來(lai)完成的(de)(de)(de)(de)(de),當(dang)含塵(chen)氣(qi)(qi)(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭時(shi),含塵(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板(ban)以及折流(liu)(liu)板(ban)的(de)(de)(de)(de)(de)調整(zheng)后,使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較均(jun)勻(yun)地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)作(zuo)用下,氣(qi)(qi)(qi)(qi)流(liu)(liu)速度迅速降低,其中(zhong)有(you)些較重的(de)(de)(de)(de)(de)塵(chen)粒(li)便失去速度而沉(chen)(chen)(chen)降下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian),則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附(fu)近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang),使氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li),電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi),這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)結合起來(lai),使塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian),帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)作(zuo)用下趨(qu)向本設(she)備(bei)陽極(ji)(正極(ji)、本設(she)備(bei)采(cai)用負高壓制)和(he)陰極(ji)(負極(ji)) , 釋放(fang)(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)(chen)(chen)積(ji)在(zai)(zai)相應(ying)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上,通(tong)過設(she)備(bei)陰陽極(ji)振(zhen)(zhen)打(da)系統的(de)(de)(de)(de)(de)振(zhen)(zhen)打(da),使沉(chen)(chen)(chen)積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落,進(jin)(jin)人(ren)集灰斗(dou) 通(tong)過排灰裝置放(fang)(fang)出,回收(shou)有(you)物料,被)凈(jing)(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入大(da)氣(qi)(qi)(qi)(qi)。
工作原(yuan)理
靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)工作(zuo)原理是(shi)利用(yong)高壓電(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)離,氣(qi)流(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣(qi)流(liu)分離。負(fu)極(ji)由不同斷面形(xing)狀(zhuang)(zhuang)的(de)(de)(de)(de)金(jin)屬導線制成(cheng),叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何(he)形(xing)狀(zhuang)(zhuang)的(de)(de)(de)(de)金(jin)屬板制成(cheng),叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構造和煙氣(qi)流(liu)速(su)等三個因素的(de)(de)(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)(zu)是(shi)評價導電(dian)(dian)(dian)性的(de)(de)(de)(de)指標(biao),它對除塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)(lv)有直接的(de)(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過低(di),塵(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang),致(zhi)使(shi)其重返(fan)氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過高,到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易放出,在(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿(chuan)和放電(dian)(dian)(dian)現象。這(zhe)些情況都會造成(cheng)除塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)(lv)下降。
電(dian)除(chu)塵器的(de)(de)基(ji)本原理(li)是利用電(dian)力(li)捕集(ji)煙氣中的(de)(de)粉塵,主要包括(kuo)以(yi)下(xia)四個相互有(you)關的(de)(de)物理(li)過(guo)程: (1) 氣體的(de)(de)電(dian)離。(2) 粉塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移動。(4) 荷電(dian)粉塵的(de)(de)捕集(ji)。
