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(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕(bu)廢氣(qi)(qi)中的粉塵(chen)(chen)，它的凈(jing)化(hua)工作上要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩(liang)個系(xi)統來完成(cheng)的，當含塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體(ti)受到(dao)氣(qi)(qi)流(liu)(liu)(liu)(liu)分(fen)布(bu)板以(yi)及折流(liu)(liu)(liu)(liu)板的調整后(hou)(hou)，使(shi)氣(qi)(qi)流(liu)(liu)(liu)(liu)能較均勻地(di)進(jin)人電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的作用下(xia)，氣(qi)(qi)流(liu)(liu)(liu)(liu)速度迅速降低，其(qi)中有些(xie)較重的塵(chen)(chen)粒(li)(li)便(bian)失(shi)去速度而沉降下(xia)來。進(jin)人電(dian)(dian)(dian)(dian)場的含塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人高壓直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)(hou)的氣(qi)(qi)體(ti)中存在(zai)(zai)大(da)量的電(dian)(dian)(dian)(dian)子和(he)離子，這些(xie)電(dian)(dian)(dian)(dian)子和(he)離子與進(jin)人電(dian)(dian)(dian)(dian)場的粉塵(chen)(chen)結(jie)合起來，使(shi)塵(chen)(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的作用下(xia)趨(qu)向本設(she)備陽(yang)極(ji)(正(zheng)極(ji)、本設(she)備采用負高壓制)和(he)陰(yin)(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分(fen)別沉積在(zai)(zai)相應的電(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設(she)備陰(yin)(yin)陽(yang)極(ji)振打系(xi)統的振打，使(shi)沉積在(zai)(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)上的粉塵(chen)(chen)振落，進(jin)人集灰(hui)斗 通(tong)過排灰(hui)裝置放出，回收有物料，被)凈(jing)化(hua)的氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)工作原理是利用(yong)高(gao)(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣流分離。負極(ji)由不同斷面形(xing)狀的(de)(de)(de)(de)金(jin)屬(shu)導(dao)線制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形(xing)狀的(de)(de)(de)(de)金(jin)屬(shu)板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)性能受粉(fen)(fen)塵(chen)(chen)(chen)性質、設備構造和煙氣流速等三個因(yin)素的(de)(de)(de)(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評(ping)價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指(zhi)標，它對除塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難(nan)以保(bao)持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高(gao)(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些情(qing)況都會造成(cheng)除塵(chen)(chen)(chen)效(xiao)率下降(jiang)。
