陵水黎族自治縣靜電除塵器廠家

靜電除塵器的(de)工作原(yuan)理是利用高壓電(dian)場使煙氣(qi)發生電(dian)離，氣(qi)流(liu)中(zhong)的(de)粉(fen)塵荷電(dian)在電(dian)場作用下與氣(qi)流(liu)分離。負極由不同斷(duan)面形狀(zhuang)的(de)金(jin)屬導線制(zhi)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(xing)(xing)能受(shou)粉(fen)塵性(xing)(xing)質、設備構造(zao)(zao)和煙(yan)氣流(liu)速等三個因素的影(ying)響(xiang)。粉(fen)塵的比電(dian)阻(zu)是評價導電(dian)性(xing)(xing)的指(zhi)標，它對(dui)除塵效(xiao)率有(you)直接的影(ying)響(xiang)。比電(dian)阻(zu)過低，塵粒(li)難(nan)以保持在集塵電(dian)極上(shang)，致使其重返氣流(liu)。比電(dian)阻(zu)過高，到達集塵電(dian)極的塵粒(li)電(dian)荷不易放(fang)(fang)出，在塵層之間形成電(dian)壓梯度會產生局部(bu)擊穿和放(fang)(fang)電(dian)現象(xiang)。這些(xie)情況都會造(zao)(zao)成除塵效(xiao)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(xing)電壓需保持(chi)40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除塵器(qi)的(de)(de)基本原理是利用(yong)電(dian)(dian)(dian)力捕集煙(yan)氣中(zhong)的(de)(de)粉塵，主要包括(kuo)以下四個相互有關(guan)的(de)(de)物理過(guo)程：（1）氣體的(de)(de)電(dian)(dian)(dian)離。（2）粉塵的(de)(de)荷電(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)粉塵向(xiang)電(dian)(dian)(dian)極移動。（4）荷電(dian)(dian)(dian)粉塵的(de)(de)捕集。

荷電粉(fen)塵的(de)捕集過(guo)程：在兩個曲率(lv)半徑(jing)相(xiang)差較(jiao)大(da)的(de)金屬陽極(ji)和(he)陰極(ji)上(shang)，通過(guo)高壓直(zhi)流電，維持一(yi)個足以(yi)使(shi)氣體(ti)電離的(de)電場，氣體(ti)電離后所產生(sheng)的(de)電子：陰離子和(he)陽離子，吸附在通過(guo)電場的(de)粉(fen)塵上(shang)，使(shi)粉(fen)塵獲得電荷。荷電極(ji)性不同的(de)粉(fen)塵在電場力的(de)作用下，分別向不同極(ji)性的(de)電極(ji)運動，沉(chen)積在電極(ji)上(shang)，而達到(dao)粉(fen)塵和(he)氣體(ti)分離的(de)目的(de)。
