博爾塔拉靜電除塵器廠家

靜電除塵器的(de)工作原(yuan)理是利用高壓電(dian)場使煙氣發生電(dian)離，氣流中的(de)粉塵荷電(dian)在電(dian)場作用下與氣流分離。負極由不同斷(duan)面形狀(zhuang)的(de)金(jin)屬導(dao)線(xian)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。靜電除塵器廠家的性能受(shou)粉(fen)塵性質、設(she)備構(gou)造和(he)煙氣流(liu)速等(deng)三(san)個因素的影(ying)響。粉(fen)塵的比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)性的指標，它對除(chu)塵效率(lv)有直接的影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵粒難以保(bao)持在集(ji)塵電(dian)(dian)(dian)(dian)(dian)極上，致使其重返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵電(dian)(dian)(dian)(dian)(dian)極的塵粒電(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵層之間(jian)形成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產(chan)生局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造成除(chu)塵效率(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，靜電除塵器運行電壓需保(bao)持40一75kV乃至(zhi)100kV以上(shang)。

工作原理

電除塵器的(de)基本原理(li)是利用電力捕集(ji)煙氣(qi)中的(de)粉(fen)(fen)塵，主要包括以(yi)下四(si)個相互有(you)關的(de)物(wu)理(li)過程(cheng)：（1）氣(qi)體的(de)電離。（2）粉(fen)(fen)塵的(de)荷(he)電。（3）荷(he)電粉(fen)(fen)塵向電極移動。（4）荷(he)電粉(fen)(fen)塵的(de)捕集(ji)。

荷電(dian)(dian)粉(fen)(fen)(fen)塵的(de)(de)捕(bu)集過程：在兩個曲(qu)率半徑相差較大的(de)(de)金屬(shu)陽極(ji)(ji)(ji)和陰極(ji)(ji)(ji)上，通(tong)過高壓直流電(dian)(dian)，維持一(yi)個足以使氣體電(dian)(dian)離(li)的(de)(de)電(dian)(dian)場，氣體電(dian)(dian)離(li)后所產生的(de)(de)電(dian)(dian)子(zi)：陰離(li)子(zi)和陽離(li)子(zi)，吸附在通(tong)過電(dian)(dian)場的(de)(de)粉(fen)(fen)(fen)塵上，使粉(fen)(fen)(fen)塵獲得(de)電(dian)(dian)荷。荷電(dian)(dian)極(ji)(ji)(ji)性(xing)不(bu)同的(de)(de)粉(fen)(fen)(fen)塵在電(dian)(dian)場力的(de)(de)作用下，分別(bie)向不(bu)同極(ji)(ji)(ji)性(xing)的(de)(de)電(dian)(dian)極(ji)(ji)(ji)運動(dong)，沉積在電(dian)(dian)極(ji)(ji)(ji)上，而達(da)到粉(fen)(fen)(fen)塵和氣體分離(li)的(de)(de)目的(de)(de)。
