儋州靜電除塵器廠家

靜電除塵器的(de)工作原(yuan)理(li)是(shi)利用高壓(ya)電場使煙(yan)氣(qi)發生電離，氣(qi)流(liu)中的(de)粉塵荷(he)電在電場作用下與(yu)氣(qi)流(liu)分離。負極(ji)由不同斷面形狀的(de)金(jin)屬導線(xian)制成，叫放電電極(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能受粉塵(chen)性質(zhi)、設備構造(zao)和(he)煙氣流速(su)等(deng)三(san)個因素(su)的影響。粉塵(chen)的比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的指(zhi)標(biao)，它對除(chu)(chu)塵(chen)效(xiao)率(lv)有直接的影響。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)粒(li)難以保持在集(ji)塵(chen)電(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣流。比電(dian)(dian)(dian)阻過(guo)高，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)極(ji)的塵(chen)粒(li)電(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)層之間形(xing)成電(dian)(dian)(dian)壓梯度會產(chan)生局部擊穿和(he)放(fang)電(dian)(dian)(dian)現(xian)象。這些情況都會造(zao)成除(chu)(chu)塵(chen)效(xiao)率(lv)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(chi)40一75kV乃(nai)至100kV以上。

工作原理

電(dian)除塵(chen)器(qi)的(de)(de)(de)(de)基(ji)本原理是利用電(dian)力捕(bu)集(ji)煙氣中的(de)(de)(de)(de)粉塵(chen)，主要包(bao)括(kuo)以下四個相互有關的(de)(de)(de)(de)物理過程：（1）氣體的(de)(de)(de)(de)電(dian)離。（2）粉塵(chen)的(de)(de)(de)(de)荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)向(xiang)電(dian)極移動。（4）荷(he)電(dian)粉塵(chen)的(de)(de)(de)(de)捕(bu)集(ji)。

荷(he)電(dian)(dian)(dian)粉(fen)塵的(de)(de)捕集過程(cheng)：在(zai)(zai)兩個曲(qu)率半徑相差較大的(de)(de)金(jin)屬陽極(ji)和(he)陰極(ji)上(shang)，通(tong)過高壓(ya)直(zhi)流電(dian)(dian)(dian)，維持(chi)一個足以使氣(qi)體(ti)電(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)離(li)后所產生的(de)(de)電(dian)(dian)(dian)子：陰離(li)子和(he)陽離(li)子，吸(xi)附在(zai)(zai)通(tong)過電(dian)(dian)(dian)場的(de)(de)粉(fen)塵上(shang)，使粉(fen)塵獲(huo)得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)性不同的(de)(de)粉(fen)塵在(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)作用下，分(fen)別向不同極(ji)性的(de)(de)電(dian)(dian)(dian)極(ji)運動(dong)，沉積在(zai)(zai)電(dian)(dian)(dian)極(ji)上(shang)，而達到粉(fen)塵和(he)氣(qi)體(ti)分(fen)離(li)的(de)(de)目的(de)(de)。

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除塵(chen)(chen)器由兩(liang)大(da)部(bu)分組成：一部(bu)分是(shi)電(dian)(dian)(dian)除塵(chen)(chen)器本體系(xi)統(tong)；另一部(bu)分是(shi)提供(gong)高(gao)(gao)壓(ya)(ya)直流電(dian)(dian)(dian)的(de)供(gong)電(dian)(dian)(dian)裝置和低壓(ya)(ya)自動控(kong)制系(xi)統(tong)。電(dian)(dian)(dian)除塵(chen)(chen)器的(de)結構原理圖如圖1所示，高(gao)(gao)壓(ya)(ya)供(gong)電(dian)(dian)(dian)系(xi)統(tong)為升壓(ya)(ya)變壓(ya)(ya)器供(gong)電(dian)(dian)(dian)，除塵(chen)(chen)器集塵(chen)(chen)極(ji)接地。低壓(ya)(ya)電(dian)(dian)(dian)控(kong)制系(xi)統(tong)用(yong)來控(kong)制電(dian)(dian)(dian)磁(ci)振打錘(chui)、卸(xie)灰電(dian)(dian)(dian)極(ji)、輸灰電(dian)(dian)(dian)極(ji)以及幾(ji)個部(bu)件的(de)溫度。
