阿克蘇靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原理是利用高壓電(dian)場(chang)(chang)使煙(yan)氣發生電(dian)離，氣流中的(de)粉塵荷電(dian)在電(dian)場(chang)(chang)作(zuo)用下(xia)與氣流分離。負極(ji)(ji)由不同斷面形狀的(de)金屬導線制(zhi)成，叫放電(dian)電(dian)極(ji)(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(shou)粉塵(chen)性質、設備構造(zao)和(he)煙氣流速等三個因素(su)的(de)(de)影響(xiang)。粉塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它(ta)對(dui)除塵(chen)效率有直接(jie)的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保持在集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿(chuan)和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成除塵(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(dian)壓需保(bao)持40一(yi)75kV乃至100kV以(yi)上(shang)。

工作原理

電(dian)除塵器的(de)基(ji)本原(yuan)理是利(li)用(yong)電(dian)力捕集(ji)煙(yan)氣中的(de)粉(fen)(fen)(fen)塵，主要(yao)包括以下四(si)個相互有關的(de)物理過(guo)程：（1）氣體的(de)電(dian)離。（2）粉(fen)(fen)(fen)塵的(de)荷電(dian)。（3）荷電(dian)粉(fen)(fen)(fen)塵向(xiang)電(dian)極移(yi)動。（4）荷電(dian)粉(fen)(fen)(fen)塵的(de)捕集(ji)。

荷(he)電(dian)(dian)粉塵的(de)(de)(de)(de)(de)捕集過程：在(zai)兩個曲率(lv)半徑相差(cha)較大的(de)(de)(de)(de)(de)金屬陽極(ji)(ji)和(he)(he)陰極(ji)(ji)上(shang)，通(tong)過高壓直流電(dian)(dian)，維(wei)持(chi)一(yi)個足(zu)以使(shi)氣(qi)(qi)體(ti)電(dian)(dian)離(li)(li)的(de)(de)(de)(de)(de)電(dian)(dian)場，氣(qi)(qi)體(ti)電(dian)(dian)離(li)(li)后(hou)所產生(sheng)的(de)(de)(de)(de)(de)電(dian)(dian)子(zi)：陰離(li)(li)子(zi)和(he)(he)陽離(li)(li)子(zi)，吸附在(zai)通(tong)過電(dian)(dian)場的(de)(de)(de)(de)(de)粉塵上(shang)，使(shi)粉塵獲得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)(ji)性不(bu)同的(de)(de)(de)(de)(de)粉塵在(zai)電(dian)(dian)場力(li)的(de)(de)(de)(de)(de)作(zuo)用下，分別向(xiang)不(bu)同極(ji)(ji)性的(de)(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)運動，沉積在(zai)電(dian)(dian)極(ji)(ji)上(shang)，而達到(dao)粉塵和(he)(he)氣(qi)(qi)體(ti)分離(li)(li)的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)由兩大(da)部分(fen)組成：一(yi)部分(fen)是電(dian)(dian)除塵(chen)(chen)(chen)器(qi)本體系(xi)統(tong)；另一(yi)部分(fen)是提供高(gao)壓(ya)(ya)(ya)直流電(dian)(dian)的供電(dian)(dian)裝置和低壓(ya)(ya)(ya)自(zi)動控制系(xi)統(tong)。電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的結(jie)構(gou)原理圖(tu)如圖(tu)1所示(shi)，高(gao)壓(ya)(ya)(ya)供電(dian)(dian)系(xi)統(tong)為(wei)升壓(ya)(ya)(ya)變壓(ya)(ya)(ya)器(qi)供電(dian)(dian)，除塵(chen)(chen)(chen)器(qi)集塵(chen)(chen)(chen)極接地。低壓(ya)(ya)(ya)電(dian)(dian)控制系(xi)統(tong)用來(lai)控制電(dian)(dian)磁(ci)振打錘、卸灰(hui)電(dian)(dian)極、輸灰(hui)電(dian)(dian)極以及幾個部件的溫度。
