(1) 由于(yu)粉塵與水相互交(jiao)融形成的霧滴具有(you)良好的導電(dian)性，因此，能夠(gou)收集靜電(dian)除塵器不能收集的黏性、高比(bi)電(dian)阻的粉塵。

(2) 沒(mei)有振(zhen)打裝(zhuang)置而采用單管單沖裝(zhuang)置，不存在二次飛揚問題，也(ye)不存在傳動裝(zhuang)置容易出故(gu)障的問題。

(3) 能(neng)提(ti)供幾倍于(yu)靜電(dian)(dian)除塵器的(de)(de)電(dian)(dian)暈功率，具有(you)很高的(de)(de)除霧(wu)除塵效率，尤其(qi)對于(yu)細小(xiao)的(de)(de)粉塵顆粒(li)、霧(wu)滴、氣溶膠(jiao)、金(jin)屬顆粒(li)、酸霧(wu)等具有(you)很強的(de)(de)捕集能(neng)力。電(dian)(dian)極(ji)(ji)(ji)之間(jian)的(de)(de)電(dian)(dian)場(chang)Ex為半(ban)徑方向(xiang)，其(qi)值為  式中:  U:施加在(zai)電(dian)(dian)極(ji)(ji)(ji)間(jian)的(de)(de)電(dian)(dian)壓；R:外部(bu)電(dian)(dian)極(ji)(ji)(ji)的(de)(de)半(ban)徑；r:內(nei)部(bu)電(dian)(dian)極(ji)(ji)(ji)的(de)(de)半(ban)徑；X:空間(jian)任一點離(li)軸線(xian)的(de)(de)距離(li)。

(4) 在采(cai)用(yong)微機控制(zhi)電(dian)源和新型放(fang)電(dian)電(dian)極(ji)的情況下，煙氣(qi)中的粉塵顆(ke)粒、霧滴、氣(qi)溶(rong)膠、金(jin)屬顆(ke)粒、酸霧等(deng)在電(dian)場(chang)的驅進速度(du)可(ke)以達到0.1m/s以上(shang)，有的高(gao)達0.19m/s。(本(ben)公司(si)生產的新型放(fang)電(dian)電(dian)極(ji)經(jing)實踐使用(yong)測得二次電(dian)暈電(dian)流大(da)于(yu)0.6mA/m。)

　　特(te)別值得注意的(de)是寬極(ji)距的(de)濕(shi)式(shi)(shi)靜電(dian)(dian)除(chu)霧除(chu)塵(chen)器，在提(ti)高除(chu)塵(chen)除(chu)霧效率，降低除(chu)塵(chen)除(chu)霧成(cheng)本方面(mian)有很大的(de)優勢，同時也是解(jie)決電(dian)(dian)暈閉塞的(de)方法之一(yi)，是目前濕(shi)式(shi)(shi)靜電(dian)(dian)除(chu)霧除(chu)塵(chen)器發展的(de)一(yi)個新趨勢。

　　總(zong)之，濕式(shi)靜(jing)電除(chu)(chu)霧除(chu)(chu)塵器(qi)特點是除(chu)(chu)霧除(chu)(chu)塵效率(lv)高，高可達到99.99%,能捕集1um左(zuo)右的粒子，且壓(ya)力損失小，一般(ban)為(wei)0.2～0.5kPa,運行穩定。由于濕式(shi)靜(jing)電除(chu)(chu)霧除(chu)(chu)塵器(qi)里有液(ye)體介(jie)質存(cun)在且溫度在露點以下，因此(ci)選材時必(bi)須考慮介(jie)質的耐溫耐腐蝕性。

電暈閉塞

　　注意當煙(yan)氣(qi)中含(han)塵(chen)、酸霧濃度(du)越(yue)高(gao)(gao)則二次電(dian)(dian)流越(yue)小。當煙(yan)氣(qi)含(han)塵(chen)霧濃度(du)高(gao)(gao)到某種程度(du)時，電(dian)(dian)場空(kong)間的(de)(de)負離子數(shu)量(liang)已(yi)不能(neng)(neng)滿足大量(liang)塵(chen)霧粒子所需(xu)，因(yin)此塵(chen)霧所得的(de)(de)能(neng)(neng)量(liang)很(hen)低(di)(di)，(表現為它的(de)(de)驅進速度(du)很(hen)低(di)(di))捕(bu)集效率(lv)顯(xian)著降(jiang)低(di)(di)，就像電(dian)(dian)場被屏蔽(bi)，故稱電(dian)(dian)暈閉塞。解(jie)決辦法是采(cai)用(yong)(yong)寬極距的(de)(de)設計以提高(gao)(gao)電(dian)(dian)壓、提高(gao)(gao)電(dian)(dian)場強度(du)；采(cai)用(yong)(yong)新型的(de)(de)放電(dian)(dian)電(dian)(dian)極以及生(sheng)產操作中采(cai)取(qu)降(jiang)低(di)(di)煙(yan)氣(qi)含(han)塵(chen)霧的(de)(de)措施等(deng)。

電暈(yun)(yun)電極(ji)(ji)肥大:氣體電離(li)產生的(de)正離(li)子被(bei)吸引(yin)回電暈(yun)(yun)電極(ji)(ji)的(de)途中，煙氣中有少(shao)量塵粒(li)被(bei)它(ta)轟(hong)擊而荷正電，便(bian)向負(fu)極(ji)(ji)性的(de)電暈(yun)(yun)電極(ji)(ji)運動并(bing)沉(chen)積(ji)在極(ji)(ji)線上而形(xing)成。解決辦法是提高運行電壓和沖洗次數。
