海口靜電除塵器廠家

靜電除塵器的(de)工作原理是利用高壓電(dian)(dian)(dian)場使煙氣發(fa)生電(dian)(dian)(dian)離(li)，氣流中的(de)粉塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣流分離(li)。負極(ji)(ji)由不同斷(duan)面(mian)形(xing)狀的(de)金屬導(dao)線制成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能受(shou)粉塵(chen)性質、設備構(gou)造和煙氣流速(su)等三個(ge)因素的影響(xiang)。粉塵(chen)的比(bi)電(dian)阻(zu)是評價導電(dian)性的指標，它(ta)對除塵(chen)效(xiao)率有直接的影響(xiang)。比(bi)電(dian)阻(zu)過(guo)低，塵(chen)粒(li)難以(yi)保(bao)持在集塵(chen)電(dian)極上，致使其(qi)重返氣流。比(bi)電(dian)阻(zu)過(guo)高，到(dao)達集塵(chen)電(dian)極的塵(chen)粒(li)電(dian)荷不易放(fang)(fang)出，在塵(chen)層(ceng)之(zhi)間形成電(dian)壓梯(ti)度會產生(sheng)局部(bu)擊穿和放(fang)(fang)電(dian)現象(xiang)。這些(xie)情況都(dou)會造成除塵(chen)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，靜電除塵器運行電(dian)壓需(xu)保(bao)持(chi)40一75kV乃至(zhi)100kV以上(shang)。

工作原理

電除塵(chen)器(qi)的(de)基(ji)本原理(li)是利(li)用電力捕集(ji)煙氣中的(de)粉塵(chen)，主要包括(kuo)以下四個(ge)相互有關的(de)物理(li)過程：（1）氣體(ti)的(de)電離(li)。（2）粉塵(chen)的(de)荷電。（3）荷電粉塵(chen)向電極移(yi)動。（4）荷電粉塵(chen)的(de)捕集(ji)。

荷電(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集過程：在兩個曲(qu)率半徑相差較大的(de)(de)金屬陽極(ji)和(he)陰極(ji)上，通過高壓直流電(dian)(dian)，維持一個足(zu)以使(shi)氣(qi)體(ti)(ti)電(dian)(dian)離的(de)(de)電(dian)(dian)場(chang)，氣(qi)體(ti)(ti)電(dian)(dian)離后所產生(sheng)的(de)(de)電(dian)(dian)子(zi)：陰離子(zi)和(he)陽離子(zi)，吸附(fu)在通過電(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)上，使(shi)粉(fen)塵(chen)(chen)獲得(de)電(dian)(dian)荷。荷電(dian)(dian)極(ji)性(xing)(xing)不同的(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)場(chang)力的(de)(de)作用下，分別向(xiang)不同極(ji)性(xing)(xing)的(de)(de)電(dian)(dian)極(ji)運動，沉積在電(dian)(dian)極(ji)上，而達到粉(fen)塵(chen)(chen)和(he)氣(qi)體(ti)(ti)分離的(de)(de)目的(de)(de)。
