三亞靜電除塵器廠家

靜電除塵器的(de)(de)工作原理是利用高壓電(dian)場(chang)使煙氣(qi)發(fa)生電(dian)離，氣(qi)流中的(de)(de)粉塵荷(he)電(dian)在電(dian)場(chang)作用下(xia)與氣(qi)流分離。負極(ji)由不同斷面(mian)形狀(zhuang)的(de)(de)金屬導線(xian)制成(cheng)，叫放電(dian)電(dian)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(de)性(xing)能(neng)受粉(fen)塵(chen)(chen)性(xing)質(zhi)、設(she)備構造(zao)(zao)和(he)煙氣(qi)流速等三(san)個因素的(de)影響。粉(fen)塵(chen)(chen)的(de)比(bi)電(dian)阻是評價導(dao)電(dian)性(xing)的(de)指(zhi)標，它對除(chu)塵(chen)(chen)效率有(you)直接的(de)影響。比(bi)電(dian)阻過低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)極上，致使其重返氣(qi)流。比(bi)電(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)極的(de)塵(chen)(chen)粒電(dian)荷不易放(fang)出，在塵(chen)(chen)層之間(jian)形成電(dian)壓梯(ti)度會產生局部(bu)擊穿(chuan)和(he)放(fang)電(dian)現象(xiang)。這些(xie)情(qing)況都會造(zao)(zao)成除(chu)塵(chen)(chen)效率下降(jiang)。

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(xu)保持40一75kV乃至100kV以上(shang)。

工作原理

電(dian)(dian)除塵(chen)器的(de)基本原理是利用電(dian)(dian)力捕集煙(yan)氣(qi)中的(de)粉塵(chen)，主要包(bao)括以下四個(ge)相(xiang)互有(you)關的(de)物理過程：（1）氣(qi)體的(de)電(dian)(dian)離。（2）粉塵(chen)的(de)荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)極移(yi)動。（4）荷(he)電(dian)(dian)粉塵(chen)的(de)捕集。

荷(he)(he)電(dian)(dian)粉(fen)塵(chen)(chen)(chen)(chen)的捕集過(guo)程：在兩個(ge)曲率半(ban)徑(jing)相差較大的金屬陽極和陰極上(shang)，通過(guo)高壓直流電(dian)(dian)，維(wei)持(chi)一個(ge)足以(yi)使氣(qi)體電(dian)(dian)離(li)的電(dian)(dian)場，氣(qi)體電(dian)(dian)離(li)后(hou)所(suo)產生的電(dian)(dian)子(zi)：陰離(li)子(zi)和陽離(li)子(zi)，吸附(fu)在通過(guo)電(dian)(dian)場的粉(fen)塵(chen)(chen)(chen)(chen)上(shang)，使粉(fen)塵(chen)(chen)(chen)(chen)獲(huo)得(de)電(dian)(dian)荷(he)(he)。荷(he)(he)電(dian)(dian)極性不(bu)同的粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)場力的作用下，分別向不(bu)同極性的電(dian)(dian)極運動(dong)，沉積在電(dian)(dian)極上(shang)，而達到(dao)粉(fen)塵(chen)(chen)(chen)(chen)和氣(qi)體分離(li)的目的。
