安康靜電除塵器廠家

靜電除塵器的工作原理是利用高壓電(dian)場使煙氣發生電(dian)離，氣流(liu)中的粉(fen)塵(chen)荷電(dian)在電(dian)場作用下與氣流(liu)分離。負極由不同斷面(mian)形狀的金(jin)屬導線制成，叫放電(dian)電(dian)極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的(de)(de)(de)性(xing)(xing)能受粉塵性(xing)(xing)質、設備(bei)構(gou)造和煙氣流(liu)速等三個因素的(de)(de)(de)影響。粉塵的(de)(de)(de)比電(dian)(dian)阻是評價導電(dian)(dian)性(xing)(xing)的(de)(de)(de)指標，它對除塵效率有直接的(de)(de)(de)影響。比電(dian)(dian)阻過低，塵粒(li)難以保(bao)持在集塵電(dian)(dian)極上，致使其重返(fan)氣流(liu)。比電(dian)(dian)阻過高，到達(da)集塵電(dian)(dian)極的(de)(de)(de)塵粒(li)電(dian)(dian)荷(he)不易放出，在塵層之間形成電(dian)(dian)壓梯(ti)度會(hui)產生(sheng)局部擊(ji)穿(chuan)和放電(dian)(dian)現象。這些情(qing)況都會(hui)造成除塵效率下降。

簡介

靜電除塵器的電源由控制箱、升壓變壓器和整流器組成。電源輸出的電壓高低對除塵效率也有很大影響。因此，靜電除塵器運行電壓需保(bao)持(chi)40一(yi)75kV乃至100kV以上。

工作原理

電除塵(chen)器的(de)基本原理(li)是利用電力捕(bu)集(ji)煙氣中(zhong)的(de)粉塵(chen)，主要(yao)包括以下四個相互有關的(de)物理(li)過程(cheng)：（1）氣體(ti)的(de)電離(li)。（2）粉塵(chen)的(de)荷(he)(he)電。（3）荷(he)(he)電粉塵(chen)向電極移動(dong)。（4）荷(he)(he)電粉塵(chen)的(de)捕(bu)集(ji)。

荷電(dian)(dian)(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)的捕(bu)集過(guo)程：在(zai)兩(liang)個曲率半(ban)徑相差較大的金屬(shu)陽極(ji)和陰極(ji)上(shang)，通過(guo)高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，維持一個足以(yi)使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)的電(dian)(dian)(dian)(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后所產生的電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽離(li)子(zi)，吸附(fu)在(zai)通過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)場的粉(fen)塵(chen)(chen)上(shang)，使(shi)(shi)粉(fen)塵(chen)(chen)獲得電(dian)(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)性不(bu)同的粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的作(zuo)用下(xia)，分別向不(bu)同極(ji)性的電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)運動，沉積(ji)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，而(er)達到(dao)粉(fen)塵(chen)(chen)和氣(qi)體(ti)分離(li)的目的。
