那曲靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原理是利用高壓電(dian)(dian)場(chang)使(shi)煙氣(qi)發(fa)生電(dian)(dian)離(li)，氣(qi)流中的(de)粉(fen)塵荷電(dian)(dian)在電(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分離(li)。負極(ji)由不同斷面形(xing)狀的(de)金屬(shu)導(dao)線(xian)制(zhi)成，叫放電(dian)(dian)電(dian)(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(de)性(xing)(xing)能受粉塵(chen)(chen)性(xing)(xing)質、設備(bei)構造(zao)和煙氣(qi)流速等(deng)三個因(yin)素的(de)影響。粉塵(chen)(chen)的(de)比(bi)電(dian)阻(zu)是評價導電(dian)性(xing)(xing)的(de)指標，它對除塵(chen)(chen)效(xiao)率有直接的(de)影響。比(bi)電(dian)阻(zu)過低，塵(chen)(chen)粒(li)(li)難(nan)以保持在(zai)集塵(chen)(chen)電(dian)極(ji)上(shang)，致使其重返氣(qi)流。比(bi)電(dian)阻(zu)過高，到達集塵(chen)(chen)電(dian)極(ji)的(de)塵(chen)(chen)粒(li)(li)電(dian)荷不易放出，在(zai)塵(chen)(chen)層之間形成電(dian)壓梯度會(hui)產生局部擊穿和放電(dian)現象。這(zhe)些(xie)情況都會(hui)造(zao)成除塵(chen)(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，靜電除塵器運行電壓(ya)需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)器(qi)的(de)(de)基本原理是利用電(dian)(dian)力(li)捕集煙(yan)氣中(zhong)的(de)(de)粉(fen)(fen)(fen)塵(chen)，主要包(bao)括以(yi)下四個(ge)相(xiang)互有(you)關的(de)(de)物理過程：（1）氣體的(de)(de)電(dian)(dian)離。（2）粉(fen)(fen)(fen)塵(chen)的(de)(de)荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉(fen)(fen)(fen)塵(chen)向(xiang)電(dian)(dian)極移(yi)動。（4）荷(he)電(dian)(dian)粉(fen)(fen)(fen)塵(chen)的(de)(de)捕集。

荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)(chen)的(de)(de)捕集過程：在兩個(ge)曲率半徑相差較大的(de)(de)金(jin)屬陽極(ji)和(he)陰(yin)(yin)極(ji)上，通過高壓(ya)直流電(dian)(dian)(dian)(dian)，維持(chi)一(yi)個(ge)足以使氣體電(dian)(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)(dian)離(li)后所產生的(de)(de)電(dian)(dian)(dian)(dian)子(zi)：陰(yin)(yin)離(li)子(zi)和(he)陽離(li)子(zi)，吸附在通過電(dian)(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)(chen)(chen)上，使粉(fen)塵(chen)(chen)(chen)獲得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)性(xing)不同的(de)(de)粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力(li)的(de)(de)作用(yong)下，分(fen)別向不同極(ji)性(xing)的(de)(de)電(dian)(dian)(dian)(dian)極(ji)運(yun)動(dong)，沉(chen)積在電(dian)(dian)(dian)(dian)極(ji)上，而達到粉(fen)塵(chen)(chen)(chen)和(he)氣體分(fen)離(li)的(de)(de)目的(de)(de)。
