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)除塵器是以(yi)靜電(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)中(zhong)的(de)粉(fen)塵，它的(de)凈化工作上(shang)要(yao)是依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個系統來(lai)完成的(de)，當含塵氣(qi)體(ti)進(jin)(jin)(jin)(jin)人(ren)(ren)氣(qi)刺叭時，含塵氣(qi)體(ti)受到氣(qi)流(liu)(liu)(liu)分布(bu)板(ban)以(yi)及折流(liu)(liu)(liu)板(ban)的(de)調整后(hou)，使氣(qi)流(liu)(liu)(liu)能較均勻地進(jin)(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴(kuo)大(da)(da)的(de)作用(yong)下，氣(qi)流(liu)(liu)(liu)速(su)度迅速(su)降低，其(qi)中(zhong)有些(xie)(xie)較重的(de)塵粒(li)便失去速(su)度而沉降下來(lai)。進(jin)(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)含塵氣(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)高(gao)壓直流(liu)(liu)(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產(chan)生電(dian)(dian)(dian)暈現象(xiang)，使氣(qi)體(ti)電(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)離(li)(li)(li)后(hou)的(de)氣(qi)體(ti)中(zhong)存在(zai)(zai)大(da)(da)量的(de)電(dian)(dian)(dian)子(zi)和離(li)(li)(li)子(zi)，這(zhe)些(xie)(xie)電(dian)(dian)(dian)子(zi)和離(li)(li)(li)子(zi)與進(jin)(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)粉(fen)塵結(jie)合起來(lai)，使塵粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵粒(li)在(zai)(zai)電(dian)(dian)(dian)場力的(de)作用(yong)下趨向(xiang)本設備(bei)(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設備(bei)(bei)采用(yong)負高(gao)壓制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)分別沉積在(zai)(zai)相(xiang)應(ying)的(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備(bei)(bei)陰(yin)陽極(ji)(ji)振打系統的(de)振打，使沉積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)粉(fen)塵振落，進(jin)(jin)(jin)(jin)人(ren)(ren)集灰斗 通過排灰裝置放(fang)出，回收有物料，被)凈化的(de)氣(qi)體(ti)排入大(da)(da)氣(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)的工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下(xia)(xia)與氣流(liu)分離。負極由(you)不同斷面形(xing)狀(zhuang)的金(jin)(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極。正極由(you)不同幾何形(xing)狀(zhuang)的金(jin)(jin)屬板制成(cheng)，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)的性能受粉(fen)塵(chen)性質(zhi)、設備構造和煙氣流(liu)速等三(san)個因素的影響。粉(fen)塵(chen)的比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)(dian)性的指標，它對除塵(chen)效(xiao)(xiao)率有直接的影響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)粒(li)難以(yi)保持在集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極上，致(zhi)使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極的塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情(qing)況都會造成(cheng)除塵(chen)效(xiao)(xiao)率下(xia)(xia)降。

電(dian)除塵(chen)器的(de)(de)基(ji)本原理是(shi)利用電(dian)力捕(bu)集煙(yan)氣中的(de)(de)粉(fen)(fen)塵(chen)，主要(yao)包括以(yi)下四個相互有(you)關的(de)(de)物理過程: (1) 氣體(ti)的(de)(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵(chen)向電(dian)極移(yi)動。(4) 荷(he)電(dian)粉(fen)(fen)塵(chen)的(de)(de)捕(bu)集。
