深圳靜電除塵器廠家

靜電除塵器的工作原(yuan)理是利用高壓電(dian)場(chang)使煙氣(qi)發(fa)生(sheng)電(dian)離，氣(qi)流(liu)中的粉塵荷電(dian)在電(dian)場(chang)作用下與氣(qi)流(liu)分離。負極(ji)由不同斷面(mian)形狀(zhuang)的金屬導線制成，叫放電(dian)電(dian)極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性(xing)能(neng)受粉塵(chen)性(xing)質、設備構造和(he)煙氣(qi)流速等三(san)個因素的影(ying)響(xiang)。粉塵(chen)的比電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性(xing)的指標(biao)，它對除塵(chen)效率有直(zhi)接的影(ying)響(xiang)。比電(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)粒(li)難以(yi)保持在集塵(chen)電(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)流。比電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)電(dian)(dian)(dian)極的塵(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在塵(chen)層之間形(xing)成電(dian)(dian)(dian)壓梯(ti)度會產生局部擊穿和(he)放電(dian)(dian)(dian)現(xian)象(xiang)。這些情況(kuang)都會造成除塵(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，靜電除塵器運行電壓(ya)需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除塵器的(de)基(ji)本(ben)原理是(shi)利用(yong)電(dian)(dian)(dian)力(li)捕(bu)集(ji)煙氣中的(de)粉塵，主要(yao)包(bao)括以下四(si)個相互有關的(de)物(wu)理過程：（1）氣體的(de)電(dian)(dian)(dian)離(li)。（2）粉塵的(de)荷電(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)粉塵向電(dian)(dian)(dian)極移(yi)動。（4）荷電(dian)(dian)(dian)粉塵的(de)捕(bu)集(ji)。

荷(he)電(dian)(dian)粉塵(chen)的(de)(de)捕集過(guo)程：在兩個曲率半(ban)徑相差較大的(de)(de)金屬陽(yang)極(ji)(ji)(ji)和陰(yin)極(ji)(ji)(ji)上，通(tong)過(guo)高壓直流電(dian)(dian)，維(wei)持(chi)一個足以(yi)使(shi)氣體(ti)電(dian)(dian)離(li)的(de)(de)電(dian)(dian)場(chang)，氣體(ti)電(dian)(dian)離(li)后所產生的(de)(de)電(dian)(dian)子：陰(yin)離(li)子和陽(yang)離(li)子，吸附在通(tong)過(guo)電(dian)(dian)場(chang)的(de)(de)粉塵(chen)上，使(shi)粉塵(chen)獲得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)(ji)(ji)性不同的(de)(de)粉塵(chen)在電(dian)(dian)場(chang)力的(de)(de)作用下，分別向(xiang)不同極(ji)(ji)(ji)性的(de)(de)電(dian)(dian)極(ji)(ji)(ji)運動，沉積在電(dian)(dian)極(ji)(ji)(ji)上，而達到粉塵(chen)和氣體(ti)分離(li)的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)由兩(liang)大部(bu)(bu)(bu)分(fen)(fen)組成：一(yi)部(bu)(bu)(bu)分(fen)(fen)是電(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)本(ben)體系統(tong)；另一(yi)部(bu)(bu)(bu)分(fen)(fen)是提供(gong)高(gao)壓(ya)直流電(dian)(dian)的供(gong)電(dian)(dian)裝置和(he)低(di)(di)壓(ya)自(zi)動控制系統(tong)。電(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的結構原(yuan)理圖(tu)如圖(tu)1所示，高(gao)壓(ya)供(gong)電(dian)(dian)系統(tong)為升壓(ya)變壓(ya)器(qi)(qi)供(gong)電(dian)(dian)，除(chu)塵(chen)(chen)器(qi)(qi)集塵(chen)(chen)極接地。低(di)(di)壓(ya)電(dian)(dian)控制系統(tong)用來控制電(dian)(dian)磁振打(da)錘、卸灰電(dian)(dian)極、輸灰電(dian)(dian)極以(yi)及(ji)幾個(ge)部(bu)(bu)(bu)件的溫度。
