鍋爐靜電除塵器維修方法：

一(yi)(yi)、在煙(yan)箱內設計預荷(he)電(dian)裝(zhuang)置(zhi)。煙(yan)箱內預荷(he)電(dian)裝(zhuang)置(zhi)為我公司的(de)(de)(de)優勢產品之一(yi)(yi)，主(zhu)要針對一(yi)(yi)電(dian)場(chang)前(qian)一(yi)(yi)、二(er)(er)塊(kuai)極板(ban)(ban)不能被充(chong)分利(li)(li)用而(er)采取的(de)(de)(de)增效(xiao)措施，即在電(dian)場(chang)煙(yan)箱靠近(jin)電(dian)場(chang)的(de)(de)(de)一(yi)(yi)層孔(kong)板(ban)(ban)前(qian)加設一(yi)(yi)排(pai)陰極線(xian)，對孔(kong)板(ban)(ban)所在的(de)(de)(de)平面放電(dian)，使粉(fen)塵(chen)預荷(he)電(dian)，這樣可充(chong)分利(li)(li)用一(yi)(yi)電(dian)場(chang)的(de)(de)(de)前(qian)一(yi)(yi)、二(er)(er)塊(kuai)陽極板(ban)(ban)的(de)(de)(de)收(shou)塵(chen)面，而(er)且孔(kong)板(ban)(ban)也(ye)具有提器收(shou)塵(chen)效(xiao)果的(de)(de)(de)功(gong)效(xiao)。

二、在靜電(dian)除(chu)塵器(qi)(qi)頂部設(she)計擋(dang)風(feng)裝(zhuang)置(zhi)，減(jian)少煙氣(qi)的(de)逃逸(yi)。為了阻止電(dian)除(chu)塵器(qi)(qi)內部煙氣(qi)的(de)直接逃逸(yi)，在電(dian)除(chu)塵器(qi)(qi)的(de)頂部合理設(she)計擋(dang)風(feng)板，使煙氣(qi)全部經過電(dian)除(chu)塵器(qi)(qi)放電(dian)區，避免的(de)含塵煙氣(qi)逃逸(yi)。

三、增(zeng)設芒(mang)刺片(pian)，放(fang)電(dian)盲區(qu)。為了原(yuan)電(dian)除(chu)塵(chen)器的放(fang)電(dian)盲區(qu)，可在陰極框架上增(zeng)設芒(mang)刺片(pian)，增(zeng)加放(fang)電(dian)點(dian)，使經過電(dian)場的煙氣*被電(dian)離，從而達(da)到提(ti)高(gao)電(dian)除(chu)塵(chen)器除(chu)塵(chen)效率(lv)的目(mu)的。

四(si)、采(cai)用(yong)高(gao)(gao)頻(pin)電(dian)(dian)(dian)(dian)(dian)源(yuan)替換普通(tong)電(dian)(dian)(dian)(dian)(dian)源(yuan)。高(gao)(gao)頻(pin)電(dian)(dian)(dian)(dian)(dian)源(yuan)近乎純直(zhi)流，其供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)就是火(huo)花電(dian)(dian)(dian)(dian)(dian)壓(ya)，放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，粒子荷電(dian)(dian)(dian)(dian)(dian)量大(da)，故一(yi)般(ban)一(yi)、二電(dian)(dian)(dian)(dian)(dian)場(chang)可(ke)以采(cai)用(yong)高(gao)(gao)頻(pin)電(dian)(dian)(dian)(dian)(dian)源(yuan)。普通(tong)單相電(dian)(dian)(dian)(dian)(dian)源(yuan)在(zai)相同的電(dian)(dian)(dian)(dian)(dian)壓(ya)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)點，電(dian)(dian)(dian)(dian)(dian)源(yuan)峰值電(dian)(dian)(dian)(dian)(dian)壓(ya)高(gao)(gao)，放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)強(qiang)烈，尤其是末(mo)電(dian)(dian)(dian)(dian)(dian)場(chang)微細(xi)粉(fen)塵多，更利(li)于微細(xi)粉(fen)塵的電(dian)(dian)(dian)(dian)(dian)離，故三(san)、四(si)電(dian)(dian)(dian)(dian)(dian)場(chang)仍(reng)采(cai)用(yong)普通(tong)電(dian)(dian)(dian)(dian)(dian)源(yuan)，這樣(yang)不僅(jin)可(ke)以節約(yue)成本，又能提高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)除塵器整體放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)性能。

五、改進(jin)(jin)電除塵(chen)(chen)(chen)器出(chu)口(kou)煙箱(xiang)的(de)(de)設計(ji)，利(li)用斜(xie)氣流(liu)(liu)技術優化(hua)粉塵(chen)(chen)(chen)的(de)(de)沉(chen)降效(xiao)果。改進(jin)(jin)型(xing)出(chu)口(kou)封(feng)(feng)頭將上(shang)(shang)下(xia)封(feng)(feng)板(ban)(ban)設計(ji)成(cheng)(cheng)上(shang)(shang)下(xia)不對稱型(xing)，下(xia)側(ce)的(de)(de)封(feng)(feng)板(ban)(ban)傾斜(xie)度加大(da)，這樣煙氣流(liu)(liu)速在末電場內(nei)呈上(shang)(shang)大(da)下(xia)小(xiao)，即末電場和(he)出(chu)口(kou)煙箱(xiang)內(nei)下(xia)側(ce)氣流(liu)(liu)流(liu)(liu)速較低，上(shang)(shang)部(bu)流(liu)(liu)速較高(gao)，有利(li)于煙氣中灰塵(chen)(chen)(chen)的(de)(de)沉(chen)降。下(xia)側(ce)封(feng)(feng)板(ban)(ban)傾斜(xie)度加大(da)，也有利(li)于沉(chen)積在出(chu)口(kou)煙箱(xiang)下(xia)側(ce)板(ban)(ban)上(shang)(shang)的(de)(de)灰塵(chen)(chen)(chen)落入(ru)灰斗(dou)，減少末電場振打清灰造成(cheng)(cheng)的(de)(de)二次揚塵(chen)(chen)(chen)。

六、使(shi)用(yong)(yong)煙氣調(diao)質(zhi)技(ji)術(shu)，提(ti)(ti)高電(dian)除塵(chen)除塵(chen)效(xiao)率。對于原先使(shi)用(yong)(yong)標準煤(mei)能(neng)達(da)標排放的(de)電(dian)除塵(chen)器現使(shi)用(yong)(yong)劣(lie)質(zhi)低(di)硫(liu)煤(mei)將(jiang)無(wu)法達(da)到(dao)理(li)想(xiang)(xiang)運行效(xiao)率，此時提(ti)(ti)高電(dian)除塵(chen)器除塵(chen)性能(neng)具有成本效(xiao)益的(de)解決方法就(jiu)是使(shi)用(yong)(yong)“煙氣調(diao)質(zhi)技(ji)術(shu)”。我公司(si)已(yi)成功與美(mei)國燃料(liao)技(ji)術(shu)公司(si)合作(zuo)，有著全套的(de)煙氣調(diao)質(zhi)技(ji)術(shu)，用(yong)(yong)理(li)想(xiang)(xiang)的(de)設計結合自控，以組裝(zhuang)好的(de)集裝(zhuang)箱式(shi)系統，提(ti)(ti)供提(ti)(ti)高電(dian)除塵(chen)器集灰(hui)性能(neng)理(li)想(xiang)(xiang)性價(jia)比的(de)解決方法和服務，解決電(dian)除塵(chen)器因煙氣性質(zhi)變化(hua)無(wu)法達(da)到(dao)性能(neng)的(de)根本問(wen)題。
