撫州靜電除塵器廠家

靜電除塵器的工(gong)作(zuo)原理是利(li)用高壓電(dian)場(chang)使(shi)煙(yan)氣發生電(dian)離，氣流中的粉塵(chen)荷電(dian)在電(dian)場(chang)作(zuo)用下與(yu)氣流分離。負(fu)極(ji)由(you)不同(tong)斷面(mian)形狀的金屬(shu)導線(xian)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(xing)能受(shou)粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣流速等(deng)三(san)個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)阻(zu)是評價導電(dian)性(xing)的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)影響。比電(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)粒(li)難以(yi)保持在集塵(chen)(chen)(chen)(chen)電(dian)極上，致使其重返氣流。比電(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)電(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)荷不易放出，在塵(chen)(chen)(chen)(chen)層之間形成電(dian)壓梯(ti)度(du)會產生局部擊穿(chuan)和(he)放電(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)(chen)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(xu)保持40一75kV乃至100kV以(yi)上。

工作原理

電(dian)(dian)除塵器的基本(ben)原理是利用電(dian)(dian)力捕集(ji)煙(yan)氣中的粉(fen)(fen)塵，主要包括以下四(si)個相互有關的物理過程：（1）氣體的電(dian)(dian)離。（2）粉(fen)(fen)塵的荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移動(dong)。（4）荷電(dian)(dian)粉(fen)(fen)塵的捕集(ji)。

荷電(dian)(dian)粉塵(chen)的(de)(de)捕(bu)集過(guo)程：在(zai)(zai)兩個曲率半徑(jing)相差較(jiao)大的(de)(de)金(jin)屬陽極(ji)(ji)和陰(yin)極(ji)(ji)上，通(tong)過(guo)高壓直(zhi)流(liu)電(dian)(dian)，維持(chi)一個足以使氣體電(dian)(dian)離(li)(li)(li)的(de)(de)電(dian)(dian)場，氣體電(dian)(dian)離(li)(li)(li)后(hou)所產生的(de)(de)電(dian)(dian)子：陰(yin)離(li)(li)(li)子和陽離(li)(li)(li)子，吸附在(zai)(zai)通(tong)過(guo)電(dian)(dian)場的(de)(de)粉塵(chen)上，使粉塵(chen)獲得電(dian)(dian)荷。荷電(dian)(dian)極(ji)(ji)性不同的(de)(de)粉塵(chen)在(zai)(zai)電(dian)(dian)場力的(de)(de)作用(yong)下，分別(bie)向不同極(ji)(ji)性的(de)(de)電(dian)(dian)極(ji)(ji)運動，沉積在(zai)(zai)電(dian)(dian)極(ji)(ji)上，而達到(dao)粉塵(chen)和氣體分離(li)(li)(li)的(de)(de)目的(de)(de)。
