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)除塵器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)捕廢(fei)氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉塵，它的(de)(de)(de)(de)(de)凈化(hua)工作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀(dian)兩個系統(tong)來(lai)完成的(de)(de)(de)(de)(de)，當含(han)(han)塵氣(qi)(qi)(qi)體(ti)(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺叭時(shi)，含(han)(han)塵氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分布板以(yi)及折流板的(de)(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流能較(jiao)均勻(yun)地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴(kuo)大(da)的(de)(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)流速度(du)迅速降低，其中有些較(jiao)重(zhong)的(de)(de)(de)(de)(de)塵粒(li)便失去(qu)速度(du)而沉(chen)降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)(han)塵氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在大(da)量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉塵結合(he)起來(lai)，使(shi)塵粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作用(yong)下趨(qu)向本設備陽(yang)(yang)極(ji)(正極(ji)、本設備采(cai)用(yong)負高(gao)壓(ya)制)和陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設備陰陽(yang)(yang)極(ji)振打(da)系統(tong)的(de)(de)(de)(de)(de)振打(da)，使(shi)沉(chen)積在陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)(de)粉塵振落(luo)，進人(ren)(ren)集灰斗 通過排灰裝置放(fang)出，回收(shou)有物料，被)凈化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)工作原理是利(li)用高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)(de)粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣流(liu)(liu)分離。負極(ji)(ji)由(you)不同斷面形(xing)狀(zhuang)的(de)(de)金(jin)(jin)屬導線制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形(xing)狀(zhuang)的(de)(de)金(jin)(jin)屬板(ban)制成，叫(jiao)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)性能受(shou)粉(fen)(fen)塵(chen)性質、設備(bei)構造(zao)和(he)煙氣流(liu)(liu)速(su)等三(san)個因素的(de)(de)影響。粉(fen)(fen)塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它(ta)對除塵(chen)效率有直接(jie)的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)粒難以保(bao)持在(zai)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使其重返氣流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)層之間(jian)形(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會(hui)(hui)產生局部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造(zao)成除塵(chen)效率下(xia)降。

電(dian)除(chu)塵(chen)(chen)器的基本(ben)原理是利(li)用電(dian)力捕(bu)集(ji)煙氣(qi)中的粉塵(chen)(chen)，主要包括以(yi)下四個相互有(you)關的物理過程(cheng): (1) 氣(qi)體(ti)(ti)的電(dian)離。(2) 粉塵(chen)(chen)的荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向電(dian)極移動。(4) 荷電(dian)粉塵(chen)(chen)的捕(bu)集(ji)。
