金昌靜電除塵器廠家

靜電除塵器的工作原(yuan)理是利用高壓電場使煙氣(qi)發生電離，氣(qi)流中的粉塵荷電在(zai)電場作用下與氣(qi)流分(fen)離。負(fu)極(ji)由不同斷(duan)面形狀的金屬導線制(zhi)成(cheng)，叫放電電極(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)性能受粉塵(chen)性質、設備(bei)構(gou)造和煙氣流速(su)等(deng)三個因素(su)的(de)影(ying)響(xiang)。粉塵(chen)的(de)比電(dian)阻(zu)是評價導電(dian)性的(de)指標，它對除塵(chen)效率有直(zhi)接的(de)影(ying)響(xiang)。比電(dian)阻(zu)過(guo)低，塵(chen)粒難(nan)以保持在集塵(chen)電(dian)極上，致使(shi)其重返氣流。比電(dian)阻(zu)過(guo)高(gao)，到達集塵(chen)電(dian)極的(de)塵(chen)粒電(dian)荷不易放出，在塵(chen)層之(zhi)間形成(cheng)(cheng)電(dian)壓梯(ti)度(du)會產(chan)生(sheng)局(ju)部(bu)擊(ji)穿和放電(dian)現象。這(zhe)些情況都會造成(cheng)(cheng)除塵(chen)效率下降(jiang)。

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(yi)上(shang)。

工作原理

電(dian)(dian)除塵器(qi)的(de)(de)基(ji)本原理是利用電(dian)(dian)力捕集煙氣中的(de)(de)粉塵，主要包(bao)括以下四個相(xiang)互(hu)有關的(de)(de)物理過(guo)程：（1）氣體的(de)(de)電(dian)(dian)離(li)。（2）粉塵的(de)(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉塵向電(dian)(dian)極(ji)移動。（4）荷電(dian)(dian)粉塵的(de)(de)捕集。

荷電(dian)(dian)(dian)(dian)(dian)粉塵(chen)的(de)(de)(de)(de)捕集過程：在(zai)(zai)兩個曲(qu)率半徑相差較(jiao)大(da)的(de)(de)(de)(de)金屬陽(yang)極(ji)(ji)和陰極(ji)(ji)上(shang)，通過高壓直流電(dian)(dian)(dian)(dian)(dian)，維持(chi)一個足以使氣(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)場(chang)，氣(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)后(hou)所產(chan)生的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子：陰離(li)(li)(li)子和陽(yang)離(li)(li)(li)子，吸附在(zai)(zai)通過電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)上(shang)，使粉塵(chen)獲(huo)得(de)電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)性(xing)不同的(de)(de)(de)(de)粉塵(chen)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用下，分別向不同極(ji)(ji)性(xing)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)運(yun)動，沉積在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，而達到粉塵(chen)和氣(qi)體分離(li)(li)(li)的(de)(de)(de)(de)目的(de)(de)(de)(de)。
