攀枝花靜電除塵器廠家

靜電除塵器的工作(zuo)(zuo)原理是利(li)用(yong)高(gao)壓電(dian)(dian)場使煙(yan)氣發生電(dian)(dian)離(li)，氣流中的粉塵荷(he)電(dian)(dian)在電(dian)(dian)場作(zuo)(zuo)用(yong)下與氣流分離(li)。負極由不同斷面(mian)形狀的金(jin)屬導線制成，叫放電(dian)(dian)電(dian)(dian)極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構造(zao)和(he)煙氣流速等(deng)三個因素的影響(xiang)(xiang)。粉塵(chen)(chen)(chen)的比電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性(xing)的指標，它對除塵(chen)(chen)(chen)效率有(you)直接的影響(xiang)(xiang)。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒(li)難(nan)以保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其(qi)重返氣流。比電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)層之間(jian)形成電(dian)(dian)(dian)壓梯度會產生局部擊穿和(he)放電(dian)(dian)(dian)現象(xiang)。這些情況(kuang)都會造(zao)成除塵(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(yun)行電壓(ya)需保(bao)持40一75kV乃至100kV以上。

工作原理

電(dian)除塵器的(de)基本原理是利(li)用電(dian)力捕(bu)集(ji)煙氣中的(de)粉塵，主要包括(kuo)以下四個相互(hu)有(you)關的(de)物理過程(cheng)：（1）氣體(ti)的(de)電(dian)離。（2）粉塵的(de)荷電(dian)。（3）荷電(dian)粉塵向電(dian)極(ji)移動(dong)。（4）荷電(dian)粉塵的(de)捕(bu)集(ji)。

荷(he)(he)電(dian)(dian)粉(fen)(fen)塵的(de)捕集過(guo)程：在兩個(ge)曲率(lv)半徑相(xiang)差較大的(de)金屬陽極和陰極上(shang)，通過(guo)高壓(ya)直流電(dian)(dian)，維(wei)持一個(ge)足以使氣(qi)(qi)體(ti)電(dian)(dian)離的(de)電(dian)(dian)場(chang)(chang)，氣(qi)(qi)體(ti)電(dian)(dian)離后(hou)所產生的(de)電(dian)(dian)子(zi)：陰離子(zi)和陽離子(zi)，吸附在通過(guo)電(dian)(dian)場(chang)(chang)的(de)粉(fen)(fen)塵上(shang)，使粉(fen)(fen)塵獲得電(dian)(dian)荷(he)(he)。荷(he)(he)電(dian)(dian)極性(xing)(xing)不同的(de)粉(fen)(fen)塵在電(dian)(dian)場(chang)(chang)力(li)的(de)作用下，分(fen)別向不同極性(xing)(xing)的(de)電(dian)(dian)極運動，沉(chen)積在電(dian)(dian)極上(shang)，而達到粉(fen)(fen)塵和氣(qi)(qi)體(ti)分(fen)離的(de)目(mu)的(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除塵(chen)器由兩大部(bu)分組(zu)成：一(yi)部(bu)分是電(dian)(dian)(dian)除塵(chen)器本體系(xi)統(tong)；另一(yi)部(bu)分是提供(gong)高(gao)壓(ya)直流電(dian)(dian)(dian)的供(gong)電(dian)(dian)(dian)裝置和低壓(ya)自動控(kong)制系(xi)統(tong)。電(dian)(dian)(dian)除塵(chen)器的結(jie)構(gou)原理圖(tu)如圖(tu)1所(suo)示，高(gao)壓(ya)供(gong)電(dian)(dian)(dian)系(xi)統(tong)為升(sheng)壓(ya)變壓(ya)器供(gong)電(dian)(dian)(dian)，除塵(chen)器集塵(chen)極接地。低壓(ya)電(dian)(dian)(dian)控(kong)制系(xi)統(tong)用來控(kong)制電(dian)(dian)(dian)磁振打錘、卸灰電(dian)(dian)(dian)極、輸(shu)灰電(dian)(dian)(dian)極以及幾個部(bu)件的溫度。
