巴音郭楞靜電除塵器廠家

靜電除塵器的(de)工作原理是利(li)用(yong)高(gao)壓電(dian)場使煙(yan)氣發生電(dian)離，氣流中的(de)粉塵荷電(dian)在電(dian)場作用(yong)下與(yu)氣流分離。負極由不同斷(duan)面形狀的(de)金屬導線制成，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(xing)(xing)能受粉塵(chen)性(xing)(xing)質(zhi)、設備構(gou)造和煙氣流速等三個因(yin)素的影響。粉塵(chen)的比電(dian)(dian)阻是評價導電(dian)(dian)性(xing)(xing)的指標，它對除塵(chen)效率有直接的影響。比電(dian)(dian)阻過低，塵(chen)粒難以保持在集塵(chen)電(dian)(dian)極上，致(zhi)使其重返氣流。比電(dian)(dian)阻過高，到達集塵(chen)電(dian)(dian)極的塵(chen)粒電(dian)(dian)荷不易放(fang)出，在塵(chen)層之間形成電(dian)(dian)壓梯度會產生局部擊穿(chuan)和放(fang)電(dian)(dian)現象。這些情(qing)況(kuang)都(dou)會造成除塵(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(xing)電壓需保(bao)持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)除(chu)塵(chen)器(qi)的基(ji)本原理是(shi)利用(yong)電(dian)(dian)力捕(bu)集(ji)煙氣中的粉(fen)塵(chen)，主要包(bao)括以下(xia)四個相(xiang)互有關的物理過程：（1）氣體的電(dian)(dian)離。（2）粉(fen)塵(chen)的荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。（4）荷電(dian)(dian)粉(fen)塵(chen)的捕(bu)集(ji)。

荷電(dian)(dian)(dian)(dian)(dian)粉(fen)塵的捕集過程：在兩個曲率半(ban)徑(jing)相差較大的金(jin)屬陽(yang)極(ji)(ji)和陰極(ji)(ji)上(shang)，通過高壓直流電(dian)(dian)(dian)(dian)(dian)，維持(chi)一個足以使(shi)氣體電(dian)(dian)(dian)(dian)(dian)離(li)的電(dian)(dian)(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)(dian)(dian)離(li)后所產生的電(dian)(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽(yang)離(li)子(zi)，吸附在通過電(dian)(dian)(dian)(dian)(dian)場的粉(fen)塵上(shang)，使(shi)粉(fen)塵獲(huo)得電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)性不(bu)同(tong)的粉(fen)塵在電(dian)(dian)(dian)(dian)(dian)場力的作用下，分(fen)別向不(bu)同(tong)極(ji)(ji)性的電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)運動，沉積在電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，而達到粉(fen)塵和氣體分(fen)離(li)的目的。
