清遠靜電除塵器廠家

靜電除塵器的(de)(de)工作原理是利(li)用(yong)(yong)高壓(ya)電場(chang)使煙氣(qi)發生(sheng)電離，氣(qi)流中的(de)(de)粉塵荷電在電場(chang)作用(yong)(yong)下與氣(qi)流分(fen)離。負極(ji)由(you)不同(tong)斷面形狀的(de)(de)金屬導線(xian)制成(cheng)，叫放電電極(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(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)流速等三個因(yin)素的影響(xiang)。粉(fen)塵(chen)(chen)的比(bi)電(dian)阻是評價導(dao)電(dian)性(xing)的指(zhi)標，它對(dui)除塵(chen)(chen)效率有直接的影響(xiang)。比(bi)電(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)極(ji)(ji)上(shang)，致使其(qi)重返氣(qi)流。比(bi)電(dian)阻過高，到(dao)達集塵(chen)(chen)電(dian)極(ji)(ji)的塵(chen)(chen)粒電(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)層之間形成(cheng)電(dian)壓梯度會(hui)產生局部擊(ji)穿和放電(dian)現象。這些情況都會(hui)造(zao)成(cheng)除塵(chen)(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(yun)行電壓(ya)需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除(chu)塵器的(de)(de)基(ji)本原(yuan)理(li)是利用電(dian)(dian)力捕(bu)集煙氣中的(de)(de)粉(fen)塵，主要包(bao)括(kuo)以下(xia)四個(ge)相互有關的(de)(de)物(wu)理(li)過程：（1）氣體的(de)(de)電(dian)(dian)離。（2）粉(fen)塵的(de)(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)塵向(xiang)電(dian)(dian)極移動。（4）荷電(dian)(dian)粉(fen)塵的(de)(de)捕(bu)集。

荷電(dian)粉塵的(de)(de)捕集過(guo)程：在兩個曲率半徑相差較大的(de)(de)金屬陽(yang)極(ji)和陰(yin)極(ji)上，通過(guo)高壓(ya)直流電(dian)，維持一個足以使(shi)氣(qi)體電(dian)離的(de)(de)電(dian)場，氣(qi)體電(dian)離后(hou)所產生的(de)(de)電(dian)子：陰(yin)離子和陽(yang)離子，吸附在通過(guo)電(dian)場的(de)(de)粉塵上，使(shi)粉塵獲得電(dian)荷。荷電(dian)極(ji)性(xing)不同(tong)的(de)(de)粉塵在電(dian)場力的(de)(de)作用(yong)下，分別(bie)向不同(tong)極(ji)性(xing)的(de)(de)電(dian)極(ji)運(yun)動，沉積在電(dian)極(ji)上，而達到粉塵和氣(qi)體分離的(de)(de)目的(de)(de)。
