哈密靜電除塵器廠家

靜電除塵器的工作原理是(shi)利用高壓電(dian)(dian)場(chang)使(shi)煙氣發(fa)生電(dian)(dian)離，氣流(liu)中的粉塵荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣流(liu)分離。負極(ji)(ji)由不同斷面(mian)形狀的金屬導線制成，叫放電(dian)(dian)電(dian)(dian)極(ji)(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)(de)性能受粉塵(chen)(chen)(chen)(chen)(chen)性質、設(she)備構(gou)造和(he)煙氣流速等三個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻是(shi)評價導電(dian)(dian)性的(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)難(nan)以保持(chi)在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極上，致使(shi)其重返氣流。比(bi)電(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)電(dian)(dian)荷(he)不易放出，在塵(chen)(chen)(chen)(chen)(chen)層之間形成電(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿(chuan)和(he)放電(dian)(dian)現象。這些情況都會(hui)造成除塵(chen)(chen)(chen)(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需保(bao)持40一75kV乃至100kV以上。

工作原理

電(dian)除塵器的(de)(de)基本原理(li)是利(li)用電(dian)力捕集煙氣中的(de)(de)粉塵，主要包括以下四個相互有(you)關(guan)的(de)(de)物理(li)過程：（1）氣體(ti)的(de)(de)電(dian)離。（2）粉塵的(de)(de)荷(he)(he)電(dian)。（3）荷(he)(he)電(dian)粉塵向電(dian)極移動。（4）荷(he)(he)電(dian)粉塵的(de)(de)捕集。

荷電(dian)(dian)粉(fen)塵的(de)(de)捕集過程(cheng)：在(zai)(zai)兩個(ge)曲率(lv)半(ban)徑(jing)相差較大的(de)(de)金屬陽極(ji)和陰極(ji)上(shang)，通過高壓直流電(dian)(dian)，維持(chi)一個(ge)足以使(shi)氣體(ti)電(dian)(dian)離的(de)(de)電(dian)(dian)場，氣體(ti)電(dian)(dian)離后所(suo)產生(sheng)的(de)(de)電(dian)(dian)子(zi)：陰離子(zi)和陽離子(zi)，吸附在(zai)(zai)通過電(dian)(dian)場的(de)(de)粉(fen)塵上(shang)，使(shi)粉(fen)塵獲得電(dian)(dian)荷。荷電(dian)(dian)極(ji)性(xing)不(bu)同(tong)的(de)(de)粉(fen)塵在(zai)(zai)電(dian)(dian)場力的(de)(de)作用下，分別向不(bu)同(tong)極(ji)性(xing)的(de)(de)電(dian)(dian)極(ji)運動，沉積在(zai)(zai)電(dian)(dian)極(ji)上(shang)，而達到粉(fen)塵和氣體(ti)分離的(de)(de)目(mu)的(de)(de)。
