慶陽靜電除塵器廠家

靜電除塵器的工作原理是利用高壓電(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)離，氣(qi)流中(zhong)的粉塵荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣(qi)流分離。負極由不同(tong)斷面(mian)形(xing)狀的金屬導線制成，叫放電(dian)(dian)電(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(xing)(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)(xing)質、設備構造(zao)和煙氣(qi)流(liu)速等三個因素的影(ying)響。粉塵(chen)(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)性(xing)(xing)的指標，它(ta)對除塵(chen)(chen)(chen)(chen)效(xiao)率有直(zhi)接(jie)的影(ying)響。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷(he)不易(yi)放出(chu)，在塵(chen)(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)現象。這些情況都會造(zao)成除塵(chen)(chen)(chen)(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(yun)行電壓需保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)除塵器(qi)的基本(ben)原理是利用電(dian)力(li)捕集煙氣中的粉塵，主要包括以下四個(ge)相互有關的物理過(guo)程：（1）氣體的電(dian)離。（2）粉塵的荷(he)電(dian)。（3）荷(he)電(dian)粉塵向(xiang)電(dian)極移動。（4）荷(he)電(dian)粉塵的捕集。

荷(he)電(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)(de)(de)捕集過(guo)程：在兩個(ge)曲率(lv)半徑相(xiang)差較大的(de)(de)(de)(de)金屬陽極(ji)(ji)和陰(yin)(yin)極(ji)(ji)上(shang)，通(tong)過(guo)高壓直流(liu)電(dian)(dian)(dian)，維(wei)持一個(ge)足以(yi)使氣體電(dian)(dian)(dian)離(li)的(de)(de)(de)(de)電(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)離(li)后(hou)所產生的(de)(de)(de)(de)電(dian)(dian)(dian)子：陰(yin)(yin)離(li)子和陽離(li)子，吸附在通(tong)過(guo)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)塵(chen)上(shang)，使粉(fen)(fen)塵(chen)獲得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)(ji)性不同(tong)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下，分別向不同(tong)極(ji)(ji)性的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)運動(dong)，沉積在電(dian)(dian)(dian)極(ji)(ji)上(shang)，而達到粉(fen)(fen)塵(chen)和氣體分離(li)的(de)(de)(de)(de)目的(de)(de)(de)(de)。
