烏海靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利用(yong)(yong)高壓電場(chang)使煙氣發生(sheng)電離(li)，氣流中的粉塵(chen)荷電在電場(chang)作(zuo)用(yong)(yong)下(xia)與(yu)氣流分離(li)。負極(ji)由不同斷面形狀的金(jin)屬導(dao)線制(zhi)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(de)性能受粉塵(chen)性質、設(she)備構(gou)造和(he)煙(yan)氣(qi)流速(su)等三個因素的(de)影(ying)響(xiang)。粉塵(chen)的(de)比電(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)性的(de)指標(biao)，它對除塵(chen)效率有直接的(de)影(ying)響(xiang)。比電(dian)(dian)阻(zu)過低，塵(chen)粒難以保持在集塵(chen)電(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)流。比電(dian)(dian)阻(zu)過高，到達集塵(chen)電(dian)(dian)極(ji)的(de)塵(chen)粒電(dian)(dian)荷(he)不易放出，在塵(chen)層之間形(xing)成電(dian)(dian)壓梯(ti)度會產生局部擊穿(chuan)和(he)放電(dian)(dian)現象。這(zhe)些情況都會造成除塵(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，靜電除塵器運行電壓需保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)除塵器(qi)的(de)(de)基本(ben)原理(li)是利用電(dian)力捕(bu)集(ji)煙氣(qi)中的(de)(de)粉(fen)塵，主要包括以下四個相(xiang)互有關的(de)(de)物理(li)過程：（1）氣(qi)體的(de)(de)電(dian)離。（2）粉(fen)塵的(de)(de)荷電(dian)。（3）荷電(dian)粉(fen)塵向電(dian)極移(yi)動。（4）荷電(dian)粉(fen)塵的(de)(de)捕(bu)集(ji)。

荷電(dian)(dian)(dian)(dian)(dian)粉塵的(de)(de)捕集過程：在(zai)兩個曲率半徑(jing)相差較大的(de)(de)金屬陽(yang)極(ji)和(he)陰極(ji)上，通(tong)過高壓直流電(dian)(dian)(dian)(dian)(dian)，維持一個足以(yi)使氣體(ti)電(dian)(dian)(dian)(dian)(dian)離的(de)(de)電(dian)(dian)(dian)(dian)(dian)場，氣體(ti)電(dian)(dian)(dian)(dian)(dian)離后所產生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子：陰離子和(he)陽(yang)離子，吸附在(zai)通(tong)過電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵上，使粉塵獲得(de)電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極(ji)性不同的(de)(de)粉塵在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)下，分別向不同極(ji)性的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)運動(dong)，沉積在(zai)電(dian)(dian)(dian)(dian)(dian)極(ji)上，而達到粉塵和(he)氣體(ti)分離的(de)(de)目的(de)(de)。

基本結構

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)由兩大(da)部(bu)分組成：一部(bu)分是電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)本體系(xi)(xi)統；另一部(bu)分是提(ti)供高壓(ya)直流電(dian)(dian)(dian)的供電(dian)(dian)(dian)裝(zhuang)置和低壓(ya)自(zi)動(dong)控(kong)(kong)制(zhi)系(xi)(xi)統。電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)的結構原理圖如圖1所示，高壓(ya)供電(dian)(dian)(dian)系(xi)(xi)統為(wei)升壓(ya)變壓(ya)器(qi)供電(dian)(dian)(dian)，除(chu)(chu)塵(chen)器(qi)集塵(chen)極接地。低壓(ya)電(dian)(dian)(dian)控(kong)(kong)制(zhi)系(xi)(xi)統用來(lai)控(kong)(kong)制(zhi)電(dian)(dian)(dian)磁振打錘、卸灰(hui)(hui)電(dian)(dian)(dian)極、輸灰(hui)(hui)電(dian)(dian)(dian)極以及(ji)幾個(ge)部(bu)件的溫度。
