定安縣靜電除塵器廠家

靜電除塵器的工作原理是利(li)用高壓電(dian)場(chang)使煙氣發生電(dian)離(li)，氣流中的粉塵(chen)荷電(dian)在電(dian)場(chang)作用下與氣流分(fen)離(li)。負極由不同斷面形(xing)狀的金(jin)屬導線制成(cheng)，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粉塵性質、設備(bei)構造和煙氣流速等三個因素的影響。粉塵的比(bi)電(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)性的指標，它對除(chu)(chu)塵效率有直接(jie)的影響。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵粒(li)難以(yi)保(bao)持(chi)在集塵電(dian)(dian)(dian)(dian)極上，致使其重返氣流。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達集塵電(dian)(dian)(dian)(dian)極的塵粒(li)電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵層之間形成電(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局(ju)部擊穿(chuan)和放電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會(hui)造成除(chu)(chu)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(ya)需保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)除(chu)塵(chen)器的(de)基本原理是利用(yong)電(dian)力(li)捕集煙氣(qi)中的(de)粉塵(chen)，主(zhu)要包括以下四個相互有關的(de)物理過程：（1）氣(qi)體的(de)電(dian)離。（2）粉塵(chen)的(de)荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)向(xiang)電(dian)極移動。（4）荷(he)電(dian)粉塵(chen)的(de)捕集。

荷(he)電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕集(ji)過程：在(zai)兩個曲率半徑相差較大(da)的(de)金屬(shu)陽極(ji)(ji)和陰(yin)極(ji)(ji)上，通過高(gao)壓直流電(dian)(dian)(dian)，維持(chi)一個足以使(shi)氣體電(dian)(dian)(dian)離(li)的(de)電(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)離(li)后所(suo)產(chan)生(sheng)的(de)電(dian)(dian)(dian)子(zi)：陰(yin)離(li)子(zi)和陽離(li)子(zi)，吸附在(zai)通過電(dian)(dian)(dian)場(chang)的(de)粉(fen)(fen)塵(chen)(chen)上，使(shi)粉(fen)(fen)塵(chen)(chen)獲得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)(ji)性不同的(de)粉(fen)(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場(chang)力的(de)作用下，分(fen)別向不同極(ji)(ji)性的(de)電(dian)(dian)(dian)極(ji)(ji)運動，沉積在(zai)電(dian)(dian)(dian)極(ji)(ji)上，而(er)達到(dao)粉(fen)(fen)塵(chen)(chen)和氣體分(fen)離(li)的(de)目的(de)。
