遼寧靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原(yuan)理是利用高壓電(dian)(dian)場使煙氣發生電(dian)(dian)離(li)，氣流中的(de)粉塵(chen)荷電(dian)(dian)在電(dian)(dian)場作(zuo)用下與氣流分離(li)。負(fu)極由不同斷面形狀的(de)金屬導(dao)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(de)(de)性(xing)(xing)能受(shou)粉塵(chen)性(xing)(xing)質、設備構造(zao)和煙氣流速等三個因素的(de)(de)影響(xiang)。粉塵(chen)的(de)(de)比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)(xing)的(de)(de)指標(biao)，它對除塵(chen)效(xiao)率有直接的(de)(de)影響(xiang)。比電(dian)(dian)阻(zu)過低，塵(chen)粒(li)難(nan)以保持在(zai)集塵(chen)電(dian)(dian)極上，致(zhi)使其重(zhong)返氣流。比電(dian)(dian)阻(zu)過高，到達集塵(chen)電(dian)(dian)極的(de)(de)塵(chen)粒(li)電(dian)(dian)荷不易(yi)放出，在(zai)塵(chen)層之間形成電(dian)(dian)壓梯度會(hui)產生局(ju)部擊(ji)穿和放電(dian)(dian)現象。這些(xie)情況都會(hui)造(zao)成除塵(chen)效(xiao)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(dian)壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)器的(de)基本原(yuan)理是利用電(dian)(dian)力捕(bu)集煙氣中(zhong)的(de)粉(fen)塵(chen)，主要包括以下(xia)四個相互有關的(de)物理過程：（1）氣體(ti)的(de)電(dian)(dian)離(li)。（2）粉(fen)塵(chen)的(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。（4）荷電(dian)(dian)粉(fen)塵(chen)的(de)捕(bu)集。

荷(he)電(dian)粉(fen)(fen)塵(chen)的(de)捕(bu)集過程(cheng)：在(zai)兩(liang)個曲率半徑相差較大的(de)金屬陽(yang)極(ji)和陰極(ji)上(shang)(shang)，通過高壓直流電(dian)，維持一個足以使(shi)氣(qi)體電(dian)離的(de)電(dian)場，氣(qi)體電(dian)離后所產生的(de)電(dian)子(zi)：陰離子(zi)和陽(yang)離子(zi)，吸附在(zai)通過電(dian)場的(de)粉(fen)(fen)塵(chen)上(shang)(shang)，使(shi)粉(fen)(fen)塵(chen)獲得電(dian)荷(he)。荷(he)電(dian)極(ji)性(xing)(xing)不同(tong)的(de)粉(fen)(fen)塵(chen)在(zai)電(dian)場力的(de)作用(yong)下，分別向不同(tong)極(ji)性(xing)(xing)的(de)電(dian)極(ji)運動(dong)，沉積在(zai)電(dian)極(ji)上(shang)(shang)，而達(da)到粉(fen)(fen)塵(chen)和氣(qi)體分離的(de)目的(de)。
