玉林靜電除塵器廠家

靜電除塵器的工作(zuo)原理(li)是利用高壓電(dian)(dian)場使煙氣(qi)發生(sheng)電(dian)(dian)離(li)，氣(qi)流中的粉塵荷(he)電(dian)(dian)在電(dian)(dian)場作(zuo)用下與氣(qi)流分離(li)。負極由(you)不同斷面(mian)形狀的金屬(shu)導線制成，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)性能受粉(fen)塵(chen)性質(zhi)、設備構造和(he)煙(yan)氣流(liu)速等三(san)個因素的(de)影響。粉(fen)塵(chen)的(de)比電(dian)(dian)阻是評(ping)價導電(dian)(dian)性的(de)指標，它對(dui)除塵(chen)效(xiao)率有(you)直(zhi)接的(de)影響。比電(dian)(dian)阻過(guo)低，塵(chen)粒難以保持在集塵(chen)電(dian)(dian)極上，致使(shi)其重(zhong)返氣流(liu)。比電(dian)(dian)阻過(guo)高，到達集塵(chen)電(dian)(dian)極的(de)塵(chen)粒電(dian)(dian)荷不易(yi)放(fang)出，在塵(chen)層之間形成電(dian)(dian)壓梯度會(hui)產生局部擊穿和(he)放(fang)電(dian)(dian)現(xian)象。這些情況都會(hui)造成除塵(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，靜電除塵器運行電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)除塵(chen)(chen)器的(de)基本原理是利用電(dian)力捕集煙氣中的(de)粉塵(chen)(chen)，主要包括以(yi)下四個相互有關的(de)物理過程：（1）氣體的(de)電(dian)離(li)。（2）粉塵(chen)(chen)的(de)荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)(chen)向(xiang)電(dian)極移(yi)動。（4）荷(he)電(dian)粉塵(chen)(chen)的(de)捕集。

荷(he)電(dian)(dian)(dian)粉塵的(de)(de)(de)(de)捕集(ji)過(guo)程：在兩個曲率半徑(jing)相差較大的(de)(de)(de)(de)金屬(shu)陽(yang)極(ji)(ji)和陰極(ji)(ji)上(shang)(shang)，通過(guo)高(gao)壓直流(liu)電(dian)(dian)(dian)，維持一個足以使氣(qi)體(ti)電(dian)(dian)(dian)離(li)的(de)(de)(de)(de)電(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)離(li)后所產生的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)：陰離(li)子(zi)(zi)和陽(yang)離(li)子(zi)(zi)，吸附在通過(guo)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵上(shang)(shang)，使粉塵獲得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)(ji)性(xing)不同(tong)的(de)(de)(de)(de)粉塵在電(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)作用下，分別向不同(tong)極(ji)(ji)性(xing)的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)運動(dong)，沉(chen)積在電(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，而達(da)到粉塵和氣(qi)體(ti)分離(li)的(de)(de)(de)(de)目的(de)(de)(de)(de)。
