煙臺靜電除塵器廠家

靜電除塵器的工作原(yuan)理(li)是利用(yong)高壓電(dian)(dian)場使(shi)煙(yan)氣發生電(dian)(dian)離(li)，氣流(liu)中(zhong)的粉塵荷電(dian)(dian)在電(dian)(dian)場作用(yong)下(xia)與(yu)氣流(liu)分離(li)。負極由不同斷面形狀的金(jin)屬(shu)導線制成，叫放(fang)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(de)性能受粉(fen)塵(chen)(chen)性質、設備構造和煙氣流(liu)速等三個因素(su)的(de)影(ying)響。粉(fen)塵(chen)(chen)的(de)比電(dian)阻是評價導電(dian)性的(de)指標，它對除塵(chen)(chen)效率有(you)直接的(de)影(ying)響。比電(dian)阻過低，塵(chen)(chen)粒(li)難以(yi)保持(chi)在(zai)(zai)集(ji)塵(chen)(chen)電(dian)極上，致(zhi)使其重返氣流(liu)。比電(dian)阻過高，到達(da)集(ji)塵(chen)(chen)電(dian)極的(de)塵(chen)(chen)粒(li)電(dian)荷不(bu)易放出(chu)，在(zai)(zai)塵(chen)(chen)層之間形(xing)成電(dian)壓梯度(du)會產生局部擊(ji)穿和放電(dian)現象。這些情況都會造成除塵(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，靜電除塵器運行電壓(ya)需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)(chen)器的基本原理是利用(yong)電(dian)(dian)力(li)捕集煙氣(qi)中(zhong)的粉(fen)(fen)塵(chen)(chen)，主(zhu)要包括以下四個相互有關的物理過程：（1）氣(qi)體的電(dian)(dian)離(li)。（2）粉(fen)(fen)塵(chen)(chen)的荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉(fen)(fen)塵(chen)(chen)向(xiang)電(dian)(dian)極移動。（4）荷(he)電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的捕集。

荷電(dian)(dian)(dian)(dian)粉塵(chen)的(de)(de)(de)捕集過程：在(zai)兩個曲率半徑相(xiang)差較大的(de)(de)(de)金屬陽極(ji)(ji)和陰極(ji)(ji)上(shang)，通過高壓直流電(dian)(dian)(dian)(dian)，維持(chi)一(yi)個足以(yi)使氣體電(dian)(dian)(dian)(dian)離(li)的(de)(de)(de)電(dian)(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)(dian)離(li)后(hou)所產生的(de)(de)(de)電(dian)(dian)(dian)(dian)子：陰離(li)子和陽離(li)子，吸附在(zai)通過電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)上(shang)，使粉塵(chen)獲得(de)電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)(ji)性(xing)不同(tong)的(de)(de)(de)粉塵(chen)在(zai)電(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作用下，分別(bie)向不同(tong)極(ji)(ji)性(xing)的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)運(yun)動，沉積在(zai)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，而達到粉塵(chen)和氣體分離(li)的(de)(de)(de)目的(de)(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵器(qi)由(you)兩(liang)大部(bu)(bu)分(fen)組成：一部(bu)(bu)分(fen)是電(dian)(dian)(dian)除(chu)塵器(qi)本體系統；另一部(bu)(bu)分(fen)是提供(gong)(gong)(gong)高壓直流電(dian)(dian)(dian)的(de)(de)供(gong)(gong)(gong)電(dian)(dian)(dian)裝置和低壓自動控(kong)(kong)制系統。電(dian)(dian)(dian)除(chu)塵器(qi)的(de)(de)結(jie)構(gou)原理圖如圖1所示，高壓供(gong)(gong)(gong)電(dian)(dian)(dian)系統為(wei)升壓變壓器(qi)供(gong)(gong)(gong)電(dian)(dian)(dian)，除(chu)塵器(qi)集塵極接(jie)地(di)。低壓電(dian)(dian)(dian)控(kong)(kong)制系統用來控(kong)(kong)制電(dian)(dian)(dian)磁(ci)振打錘、卸(xie)灰(hui)電(dian)(dian)(dian)極、輸(shu)灰(hui)電(dian)(dian)(dian)極以及幾個部(bu)(bu)件的(de)(de)溫度(du)。
