喀什靜電除塵器廠家

靜電除塵器的工作原(yuan)理是利用高壓電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流中(zhong)的粉塵荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下(xia)與氣(qi)流分離(li)。負極(ji)由(you)不同斷(duan)面形狀的金(jin)屬導線(xian)制成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能(neng)受粉(fen)塵(chen)(chen)性質、設(she)備構造和煙氣流(liu)速(su)等三(san)個因素的影(ying)響。粉(fen)塵(chen)(chen)的比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的指(zhi)標，它對(dui)除塵(chen)(chen)效率(lv)有直接的影(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難(nan)以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返氣流(liu)。比電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)粒電(dian)(dian)(dian)荷不易(yi)放(fang)出(chu)，在塵(chen)(chen)層之間(jian)形成電(dian)(dian)(dian)壓梯度會(hui)產(chan)生局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情況都會(hui)造成除塵(chen)(chen)效率(lv)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(xu)保持(chi)40一(yi)75kV乃至100kV以(yi)上(shang)。

工作原理

電除塵(chen)器的(de)(de)(de)基本原(yuan)理是利用電力(li)捕集煙氣中(zhong)的(de)(de)(de)粉(fen)塵(chen)，主要包括以(yi)下四(si)個(ge)相互有(you)關的(de)(de)(de)物理過程：（1）氣體的(de)(de)(de)電離。（2）粉(fen)塵(chen)的(de)(de)(de)荷電。（3）荷電粉(fen)塵(chen)向電極移(yi)動。（4）荷電粉(fen)塵(chen)的(de)(de)(de)捕集。

荷電(dian)(dian)(dian)粉(fen)(fen)(fen)塵(chen)的(de)(de)(de)(de)捕集(ji)過程：在兩(liang)個曲率半徑相差較大的(de)(de)(de)(de)金屬陽極(ji)和(he)陰極(ji)上(shang)，通(tong)過高壓直流(liu)電(dian)(dian)(dian)，維(wei)持(chi)一個足以使(shi)氣體電(dian)(dian)(dian)離(li)的(de)(de)(de)(de)電(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)離(li)后(hou)所產生的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和(he)陽離(li)子(zi)，吸(xi)附在通(tong)過電(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)(fen)塵(chen)上(shang)，使(shi)粉(fen)(fen)(fen)塵(chen)獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)性不(bu)同(tong)(tong)的(de)(de)(de)(de)粉(fen)(fen)(fen)塵(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下，分別向不(bu)同(tong)(tong)極(ji)性的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)運(yun)動，沉積在電(dian)(dian)(dian)極(ji)上(shang)，而達到(dao)粉(fen)(fen)(fen)塵(chen)和(he)氣體分離(li)的(de)(de)(de)(de)目的(de)(de)(de)(de)。
