保山靜電除塵器廠家

靜電除塵器的工作原理是利用高(gao)壓電場(chang)使(shi)煙氣發生電離(li)，氣流中的粉塵(chen)荷電在電場(chang)作用下與氣流分離(li)。負(fu)極(ji)由不(bu)同斷面形(xing)狀的金屬導線制成，叫放(fang)電電極(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)(de)性能受粉塵(chen)(chen)(chen)(chen)(chen)性質、設備構造和(he)煙氣流速(su)等三(san)個因素的(de)(de)影響(xiang)(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有(you)直接的(de)(de)影響(xiang)(xiang)。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極上，致使其重返氣流。比電(dian)(dian)阻(zu)過高，到(dao)達(da)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯(ti)度會產生局部擊(ji)穿(chuan)和(he)放電(dian)(dian)現象(xiang)。這些情(qing)況都會造成(cheng)除塵(chen)(chen)(chen)(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需保(bao)持40一75kV乃(nai)至100kV以(yi)上。

工作原理

電除塵(chen)(chen)器的(de)(de)基本原理是(shi)利用(yong)電力捕(bu)集煙(yan)氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)，主要包括以下四(si)個相互有關的(de)(de)物(wu)理過程(cheng)：（1）氣(qi)體的(de)(de)電離。（2）粉(fen)塵(chen)(chen)的(de)(de)荷電。（3）荷電粉(fen)塵(chen)(chen)向(xiang)電極移動。（4）荷電粉(fen)塵(chen)(chen)的(de)(de)捕(bu)集。

荷電(dian)(dian)(dian)(dian)粉塵(chen)的(de)捕集過程：在兩個曲率半徑相差較大的(de)金屬(shu)陽(yang)極(ji)(ji)和陰極(ji)(ji)上(shang)，通過高壓直流(liu)電(dian)(dian)(dian)(dian)，維持一個足以使(shi)氣體電(dian)(dian)(dian)(dian)離的(de)電(dian)(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)(dian)離后(hou)所(suo)產生的(de)電(dian)(dian)(dian)(dian)子(zi)：陰離子(zi)和陽(yang)離子(zi)，吸附在通過電(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)上(shang)，使(shi)粉塵(chen)獲(huo)得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)(ji)性不同的(de)粉塵(chen)在電(dian)(dian)(dian)(dian)場(chang)力的(de)作用下，分別(bie)向不同極(ji)(ji)性的(de)電(dian)(dian)(dian)(dian)極(ji)(ji)運動，沉(chen)積在電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，而達(da)到粉塵(chen)和氣體分離的(de)目的(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)由兩(liang)大部(bu)分(fen)組成：一部(bu)分(fen)是電(dian)(dian)(dian)除(chu)塵(chen)器(qi)本體系(xi)統；另一部(bu)分(fen)是提供(gong)(gong)高(gao)壓(ya)(ya)直(zhi)流電(dian)(dian)(dian)的供(gong)(gong)電(dian)(dian)(dian)裝置和(he)低壓(ya)(ya)自(zi)動(dong)控(kong)制(zhi)系(xi)統。電(dian)(dian)(dian)除(chu)塵(chen)器(qi)的結構原(yuan)理圖如圖1所示，高(gao)壓(ya)(ya)供(gong)(gong)電(dian)(dian)(dian)系(xi)統為升壓(ya)(ya)變壓(ya)(ya)器(qi)供(gong)(gong)電(dian)(dian)(dian)，除(chu)塵(chen)器(qi)集塵(chen)極(ji)接(jie)地。低壓(ya)(ya)電(dian)(dian)(dian)控(kong)制(zhi)系(xi)統用來控(kong)制(zhi)電(dian)(dian)(dian)磁振打錘、卸灰(hui)電(dian)(dian)(dian)極(ji)、輸灰(hui)電(dian)(dian)(dian)極(ji)以及幾個部(bu)件的溫(wen)度。
