汕尾靜電除塵器廠家

靜電除塵器的(de)工作原(yuan)理是利用高壓(ya)電(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)粉(fen)塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)分(fen)離。負極(ji)由不同斷面(mian)形(xing)狀的(de)金屬導(dao)線(xian)制成，叫放電(dian)(dian)(dian)電(dian)(dian)(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)性能受粉塵(chen)(chen)(chen)性質(zhi)、設備構(gou)造(zao)和(he)煙(yan)氣(qi)流速(su)等三個因素(su)的(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性的(de)指(zhi)標(biao)，它對(dui)除塵(chen)(chen)(chen)效率(lv)(lv)有(you)直接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返氣(qi)流。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯(ti)度會(hui)產(chan)生(sheng)局部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)現象(xiang)。這些情況都(dou)會(hui)造(zao)成(cheng)除塵(chen)(chen)(chen)效率(lv)(lv)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(xing)電壓需保(bao)持40一75kV乃至100kV以上。

工作原理

電(dian)除塵器的(de)(de)基本原理是利用電(dian)力捕集煙氣中的(de)(de)粉(fen)塵，主(zhu)要(yao)包括(kuo)以下四個相互(hu)有關的(de)(de)物理過程(cheng)：（1）氣體的(de)(de)電(dian)離。（2）粉(fen)塵的(de)(de)荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)塵向(xiang)電(dian)極(ji)移動(dong)。（4）荷(he)電(dian)粉(fen)塵的(de)(de)捕集。

荷(he)電(dian)(dian)粉塵的(de)捕集過(guo)程：在(zai)兩個(ge)曲率半徑相差較(jiao)大的(de)金(jin)屬陽極(ji)和(he)陰極(ji)上，通(tong)過(guo)高壓直流(liu)電(dian)(dian)，維持一(yi)個(ge)足(zu)以使氣(qi)體(ti)電(dian)(dian)離(li)的(de)電(dian)(dian)場(chang)，氣(qi)體(ti)電(dian)(dian)離(li)后所產(chan)生的(de)電(dian)(dian)子：陰離(li)子和(he)陽離(li)子，吸附在(zai)通(tong)過(guo)電(dian)(dian)場(chang)的(de)粉塵上，使粉塵獲得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)性不同的(de)粉塵在(zai)電(dian)(dian)場(chang)力的(de)作用(yong)下，分別向不同極(ji)性的(de)電(dian)(dian)極(ji)運動，沉積(ji)在(zai)電(dian)(dian)極(ji)上，而達到粉塵和(he)氣(qi)體(ti)分離(li)的(de)目(mu)的(de)。

基本結構

靜(jing)電(dian)(dian)電(dian)(dian)除(chu)(chu)塵器(qi)由兩大部(bu)(bu)分(fen)組成：一部(bu)(bu)分(fen)是(shi)電(dian)(dian)除(chu)(chu)塵器(qi)本體(ti)系統(tong)(tong)；另一部(bu)(bu)分(fen)是(shi)提供高(gao)壓(ya)直流電(dian)(dian)的供電(dian)(dian)裝(zhuang)置(zhi)和低(di)壓(ya)自(zi)動控(kong)制系統(tong)(tong)。電(dian)(dian)除(chu)(chu)塵器(qi)的結(jie)構原理圖如圖1所示，高(gao)壓(ya)供電(dian)(dian)系統(tong)(tong)為升壓(ya)變壓(ya)器(qi)供電(dian)(dian)，除(chu)(chu)塵器(qi)集塵極(ji)(ji)(ji)接地。低(di)壓(ya)電(dian)(dian)控(kong)制系統(tong)(tong)用來控(kong)制電(dian)(dian)磁振打錘、卸灰(hui)(hui)電(dian)(dian)極(ji)(ji)(ji)、輸灰(hui)(hui)電(dian)(dian)極(ji)(ji)(ji)以(yi)及幾(ji)個部(bu)(bu)件的溫度(du)。
