營口靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原理是利用高壓電(dian)場使煙氣發生電(dian)離，氣流(liu)中的(de)粉塵(chen)荷電(dian)在電(dian)場作(zuo)用下與氣流(liu)分離。負極(ji)由(you)不(bu)同(tong)斷面形狀(zhuang)的(de)金屬導線制成，叫放電(dian)電(dian)極(ji)。

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)性能受(shou)粉塵(chen)(chen)(chen)性質(zhi)、設(she)備構造(zao)(zao)和煙氣(qi)流(liu)速(su)等三(san)個因(yin)素的(de)(de)影(ying)(ying)響。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻是評價導電(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效率(lv)有(you)直接的(de)(de)影(ying)(ying)響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)極上(shang)，致(zhi)使其(qi)重返(fan)氣(qi)流(liu)。比電(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度(du)會(hui)產生局部擊穿和放(fang)電(dian)(dian)現象。這些情況都會(hui)造(zao)(zao)成(cheng)除(chu)塵(chen)(chen)(chen)效率(lv)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(yun)行電壓需保持40一75kV乃至100kV以上(shang)。

工作原理

電(dian)除塵(chen)(chen)器(qi)的基(ji)本原理(li)是(shi)利用(yong)電(dian)力捕集(ji)煙(yan)氣(qi)中的粉塵(chen)(chen)，主要包括以下四個相互有(you)關的物理(li)過程：（1）氣(qi)體的電(dian)離。（2）粉塵(chen)(chen)的荷電(dian)。（3）荷電(dian)粉塵(chen)(chen)向電(dian)極(ji)移動(dong)。（4）荷電(dian)粉塵(chen)(chen)的捕集(ji)。

荷(he)電(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)捕集過(guo)程：在(zai)兩個(ge)曲(qu)率半徑相(xiang)差(cha)較大的(de)(de)金屬陽(yang)極和(he)(he)陰極上，通過(guo)高壓直流電(dian)(dian)，維持(chi)一個(ge)足(zu)以(yi)使氣體電(dian)(dian)離(li)(li)的(de)(de)電(dian)(dian)場，氣體電(dian)(dian)離(li)(li)后所產生的(de)(de)電(dian)(dian)子：陰離(li)(li)子和(he)(he)陽(yang)離(li)(li)子，吸附在(zai)通過(guo)電(dian)(dian)場的(de)(de)粉(fen)(fen)塵(chen)上，使粉(fen)(fen)塵(chen)獲得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極性(xing)不(bu)(bu)同的(de)(de)粉(fen)(fen)塵(chen)在(zai)電(dian)(dian)場力的(de)(de)作用下(xia)，分(fen)(fen)別(bie)向不(bu)(bu)同極性(xing)的(de)(de)電(dian)(dian)極運(yun)動(dong)，沉積在(zai)電(dian)(dian)極上，而達到(dao)粉(fen)(fen)塵(chen)和(he)(he)氣體分(fen)(fen)離(li)(li)的(de)(de)目的(de)(de)。
