廣西靜電除塵器廠家

靜電除塵器的工作原理是利用高壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)離，氣流中的粉塵(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下與氣流分離。負極由不同(tong)斷面形狀的金(jin)屬導線(xian)制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(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)(de)性(xing)能受粉塵(chen)性(xing)質、設備構造(zao)和煙氣流速等三個因素的(de)(de)影響。粉塵(chen)的(de)(de)比(bi)電(dian)阻(zu)是評價導電(dian)性(xing)的(de)(de)指標(biao)，它對除塵(chen)效率有直接(jie)的(de)(de)影響。比(bi)電(dian)阻(zu)過低(di)，塵(chen)粒(li)難(nan)以(yi)保持在(zai)集塵(chen)電(dian)極(ji)上，致使其(qi)重返氣流。比(bi)電(dian)阻(zu)過高，到達集塵(chen)電(dian)極(ji)的(de)(de)塵(chen)粒(li)電(dian)荷不(bu)易放(fang)出(chu)，在(zai)塵(chen)層之間形成(cheng)電(dian)壓梯度會產(chan)生(sheng)局部擊(ji)穿和放(fang)電(dian)現象。這些情況都(dou)會造(zao)成(cheng)除塵(chen)效率下(xia)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40一75kV乃至100kV以(yi)上。

工作原理

電(dian)(dian)除(chu)塵(chen)(chen)器的(de)基本原理是利用電(dian)(dian)力捕集煙(yan)氣中的(de)粉塵(chen)(chen)，主要包括以下四個相(xiang)互有關的(de)物理過程：（1）氣體的(de)電(dian)(dian)離。（2）粉塵(chen)(chen)的(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移動。（4）荷電(dian)(dian)粉塵(chen)(chen)的(de)捕集。

荷(he)(he)電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)捕集過(guo)程(cheng)：在(zai)兩個曲率半(ban)徑相(xiang)差較(jiao)大的(de)金屬陽極(ji)和(he)陰極(ji)上，通過(guo)高壓直(zhi)流電(dian)(dian)(dian)(dian)，維持一(yi)個足以使(shi)氣體(ti)電(dian)(dian)(dian)(dian)離的(de)電(dian)(dian)(dian)(dian)場(chang)，氣體(ti)電(dian)(dian)(dian)(dian)離后所產生(sheng)的(de)電(dian)(dian)(dian)(dian)子：陰離子和(he)陽離子，吸附在(zai)通過(guo)電(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)(fen)塵(chen)上，使(shi)粉(fen)(fen)塵(chen)獲得(de)電(dian)(dian)(dian)(dian)荷(he)(he)。荷(he)(he)電(dian)(dian)(dian)(dian)極(ji)性不同的(de)粉(fen)(fen)塵(chen)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)作用下，分別向不同極(ji)性的(de)電(dian)(dian)(dian)(dian)極(ji)運動，沉積在(zai)電(dian)(dian)(dian)(dian)極(ji)上，而(er)達到粉(fen)(fen)塵(chen)和(he)氣體(ti)分離的(de)目的(de)。

靜(jing)電(dian)(dian)電(dian)(dian)除(chu)塵(chen)器(qi)(qi)由兩(liang)大部(bu)分組成(cheng)：一部(bu)分是電(dian)(dian)除(chu)塵(chen)器(qi)(qi)本體系(xi)(xi)統(tong)(tong)；另(ling)一部(bu)分是提供(gong)高(gao)壓直流電(dian)(dian)的(de)(de)供(gong)電(dian)(dian)裝置和低壓自動控(kong)(kong)制系(xi)(xi)統(tong)(tong)。電(dian)(dian)除(chu)塵(chen)器(qi)(qi)的(de)(de)結(jie)構原理圖(tu)如圖(tu)1所示，高(gao)壓供(gong)電(dian)(dian)系(xi)(xi)統(tong)(tong)為升壓變壓器(qi)(qi)供(gong)電(dian)(dian)，除(chu)塵(chen)器(qi)(qi)集塵(chen)極(ji)接地(di)。低壓電(dian)(dian)控(kong)(kong)制系(xi)(xi)統(tong)(tong)用來(lai)控(kong)(kong)制電(dian)(dian)磁振(zhen)打(da)錘、卸灰電(dian)(dian)極(ji)、輸灰電(dian)(dian)極(ji)以及幾(ji)個(ge)部(bu)件的(de)(de)溫度。
