萬寧靜電除塵器廠家

靜電除塵器的工作原理是(shi)利用高壓電(dian)場(chang)使煙氣發生電(dian)離，氣流中的粉塵荷電(dian)在(zai)電(dian)場(chang)作用下與氣流分離。負極(ji)由不同(tong)斷面形狀的金屬(shu)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)(xing)能受粉塵(chen)(chen)性(xing)(xing)質、設備構造和(he)煙氣流速等(deng)三個因素的影響。粉塵(chen)(chen)的比(bi)(bi)電(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)性(xing)(xing)的指標(biao)，它(ta)對除(chu)塵(chen)(chen)效(xiao)率(lv)有直接的影響。比(bi)(bi)電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致使其重(zhong)返氣流。比(bi)(bi)電(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)壓梯度(du)會(hui)(hui)產生(sheng)局部擊(ji)穿(chuan)和(he)放電(dian)(dian)(dian)現(xian)象(xiang)。這些情況(kuang)都會(hui)(hui)造成除(chu)塵(chen)(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，靜電除塵器運行電壓需(xu)保持40一75kV乃(nai)至100kV以上。

工作原理

電(dian)除塵(chen)器的(de)基本(ben)原(yuan)理(li)是利用電(dian)力捕集煙氣中的(de)粉塵(chen)，主要包括以下四個(ge)相互有關的(de)物理(li)過程：（1）氣體的(de)電(dian)離。（2）粉塵(chen)的(de)荷(he)(he)電(dian)。（3）荷(he)(he)電(dian)粉塵(chen)向電(dian)極移動。（4）荷(he)(he)電(dian)粉塵(chen)的(de)捕集。

荷(he)電(dian)(dian)粉塵(chen)的(de)(de)(de)捕集(ji)過程：在(zai)(zai)兩個(ge)曲(qu)率半徑相(xiang)差(cha)較大(da)的(de)(de)(de)金屬(shu)陽極(ji)和(he)(he)陰極(ji)上(shang)(shang)，通過高壓直流電(dian)(dian)，維持一個(ge)足以使氣體(ti)電(dian)(dian)離(li)的(de)(de)(de)電(dian)(dian)場(chang)(chang)(chang)，氣體(ti)電(dian)(dian)離(li)后所產生的(de)(de)(de)電(dian)(dian)子：陰離(li)子和(he)(he)陽離(li)子，吸附在(zai)(zai)通過電(dian)(dian)場(chang)(chang)(chang)的(de)(de)(de)粉塵(chen)上(shang)(shang)，使粉塵(chen)獲得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)性(xing)不同(tong)的(de)(de)(de)粉塵(chen)在(zai)(zai)電(dian)(dian)場(chang)(chang)(chang)力的(de)(de)(de)作(zuo)用(yong)下，分別向不同(tong)極(ji)性(xing)的(de)(de)(de)電(dian)(dian)極(ji)運動，沉積在(zai)(zai)電(dian)(dian)極(ji)上(shang)(shang)，而達到(dao)粉塵(chen)和(he)(he)氣體(ti)分離(li)的(de)(de)(de)目的(de)(de)(de)。
