遼源靜電除塵器廠家

靜電除塵器的工作(zuo)(zuo)原理是利用高壓電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離，氣流中的粉塵荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)(zuo)用下(xia)與(yu)氣流分離。負極由不同(tong)斷面形(xing)狀的金(jin)屬導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(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(chen)性質、設備構(gou)造(zao)和(he)煙氣流速(su)等(deng)三個因素的影響。粉塵(chen)的比電(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)性的指標(biao)，它對(dui)除(chu)塵(chen)效率有直(zhi)接(jie)的影響。比電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)粒難以保持在集塵(chen)電(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使其(qi)重返氣流。比電(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集塵(chen)電(dian)(dian)(dian)(dian)極(ji)的塵(chen)粒電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產(chan)生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)成(cheng)除(chu)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，靜電除塵器運行電壓需保持40一75kV乃至100kV以上。

工作原理

電除(chu)塵器(qi)的(de)(de)基本原理是利用電力捕(bu)集煙氣(qi)中的(de)(de)粉(fen)(fen)塵，主要包(bao)括以下(xia)四個(ge)相互有(you)關的(de)(de)物理過程：（1）氣(qi)體的(de)(de)電離。（2）粉(fen)(fen)塵的(de)(de)荷(he)(he)電。（3）荷(he)(he)電粉(fen)(fen)塵向電極移動(dong)。（4）荷(he)(he)電粉(fen)(fen)塵的(de)(de)捕(bu)集。

荷(he)電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)捕集過(guo)程(cheng)：在兩個(ge)曲率半徑相差較大的(de)(de)金屬陽(yang)極(ji)和陰(yin)極(ji)上(shang)，通過(guo)高(gao)壓直流(liu)電(dian)(dian)(dian)，維持一個(ge)足(zu)以使氣體電(dian)(dian)(dian)離的(de)(de)電(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)離后(hou)所產生的(de)(de)電(dian)(dian)(dian)子(zi)：陰(yin)離子(zi)和陽(yang)離子(zi)，吸(xi)附在通過(guo)電(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)上(shang)，使粉(fen)(fen)塵(chen)(chen)(chen)獲得(de)電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)性不同(tong)(tong)的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下，分(fen)別向(xiang)不同(tong)(tong)極(ji)性的(de)(de)電(dian)(dian)(dian)極(ji)運動，沉積在電(dian)(dian)(dian)極(ji)上(shang)，而(er)達(da)到粉(fen)(fen)塵(chen)(chen)(chen)和氣體分(fen)離的(de)(de)目的(de)(de)。
