仙桃靜電除塵器廠家

靜電除塵器的(de)(de)工(gong)作原理是利(li)用高(gao)壓(ya)電場使煙氣(qi)(qi)發生電離(li)(li)，氣(qi)(qi)流(liu)中的(de)(de)粉塵荷電在電場作用下與氣(qi)(qi)流(liu)分(fen)離(li)(li)。負極由不同(tong)斷面形狀的(de)(de)金(jin)屬(shu)導線制(zhi)成，叫放(fang)電電極。

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)性(xing)(xing)能受(shou)粉塵(chen)(chen)性(xing)(xing)質、設備(bei)構(gou)造(zao)和煙氣(qi)流速等三個因素的(de)影響(xiang)。粉塵(chen)(chen)的(de)比電(dian)(dian)阻是(shi)評價導電(dian)(dian)性(xing)(xing)的(de)指標，它對除(chu)塵(chen)(chen)效率有直接的(de)影響(xiang)。比電(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)極上(shang)，致使其重返(fan)氣(qi)流。比電(dian)(dian)阻過(guo)高(gao)，到達集(ji)塵(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)層之間形成電(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿和放電(dian)(dian)現象。這些情(qing)況都會(hui)造(zao)成除(chu)塵(chen)(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需保持40一(yi)75kV乃至(zhi)100kV以上。

工作原理

電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的基本原理是利用(yong)電(dian)(dian)(dian)(dian)力(li)捕集(ji)煙(yan)氣中(zhong)的粉塵(chen)，主要包括以(yi)下四(si)個相互有關的物理過程：（1）氣體的電(dian)(dian)(dian)(dian)離。（2）粉塵(chen)的荷電(dian)(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)(dian)極(ji)移(yi)動。（4）荷電(dian)(dian)(dian)(dian)粉塵(chen)的捕集(ji)。

荷(he)(he)電(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)捕集過程：在(zai)(zai)兩(liang)個曲率(lv)半徑相差較大的(de)(de)(de)金屬陽(yang)極(ji)(ji)和(he)(he)陰(yin)極(ji)(ji)上，通過高(gao)壓(ya)直流電(dian)(dian)，維持一個足以(yi)使氣(qi)體(ti)電(dian)(dian)離(li)的(de)(de)(de)電(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)離(li)后所產生的(de)(de)(de)電(dian)(dian)子(zi)：陰(yin)離(li)子(zi)和(he)(he)陽(yang)離(li)子(zi)，吸(xi)附(fu)在(zai)(zai)通過電(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)上，使粉(fen)塵(chen)獲得電(dian)(dian)荷(he)(he)。荷(he)(he)電(dian)(dian)極(ji)(ji)性不(bu)同的(de)(de)(de)粉(fen)塵(chen)在(zai)(zai)電(dian)(dian)場力(li)的(de)(de)(de)作用下，分別向不(bu)同極(ji)(ji)性的(de)(de)(de)電(dian)(dian)極(ji)(ji)運動，沉積(ji)在(zai)(zai)電(dian)(dian)極(ji)(ji)上，而達到粉(fen)塵(chen)和(he)(he)氣(qi)體(ti)分離(li)的(de)(de)(de)目(mu)的(de)(de)(de)。

基本結構

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除塵器由(you)兩大部(bu)分(fen)組(zu)成：一(yi)部(bu)分(fen)是電(dian)(dian)(dian)除塵器本體系(xi)統(tong)；另一(yi)部(bu)分(fen)是提供(gong)高壓(ya)(ya)直流(liu)電(dian)(dian)(dian)的(de)供(gong)電(dian)(dian)(dian)裝(zhuang)置和低壓(ya)(ya)自動控(kong)制系(xi)統(tong)。電(dian)(dian)(dian)除塵器的(de)結(jie)構原理圖如圖1所示，高壓(ya)(ya)供(gong)電(dian)(dian)(dian)系(xi)統(tong)為(wei)升壓(ya)(ya)變(bian)壓(ya)(ya)器供(gong)電(dian)(dian)(dian)，除塵器集塵極接地。低壓(ya)(ya)電(dian)(dian)(dian)控(kong)制系(xi)統(tong)用來控(kong)制電(dian)(dian)(dian)磁(ci)振打錘、卸灰(hui)電(dian)(dian)(dian)極、輸灰(hui)電(dian)(dian)(dian)極以及(ji)幾個(ge)部(bu)件的(de)溫度。
