如今我國在日(ri)益發(fa)展的經濟環(huan)境下,要(yao)(yao)求日(ri)益嚴格,電(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)煙塵(chen)(chen)排放已不能(neng)適應新(xin)標(biao)準(zhun)(zhun)的要(yao)(yao)求,將電(dian)除(chu)(chu)(chu)塵(chen)(chen)設(she)備(bei)改造(zao)成(cheng)袋式(shi)除(chu)(chu)(chu)塵(chen)(chen)器(qi)則可以(yi)實(shi)現煙塵(chen)(chen)低濃(nong)度排放,新(xin)標(biao)準(zhun)(zhun)的要(yao)(yao)求,所以(yi)說(shuo)電(dian)改袋已成(cheng)為當前乃至今后電(dian)除(chu)(chu)(chu)塵(chen)(chen)設(she)備(bei)改造(zao)的主(zhu)(zhu)流,為了(le)跟得上主(zhu)(zhu)流的步伐諾(nuo)和早(zao)已做好準(zhun)(zhun)備(bei),成(cheng)功把靜電(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)改造(zao)為布袋除(chu)(chu)(chu)塵(chen)(chen)器(qi),并且我們(men)的這一(yi)新(xin)型(xing)設(she)備(bei)成(cheng)功運(yun)用在除(chu)(chu)(chu)塵(chen)(chen)市場的領域里。
拆除(chu)(chu)電除(chu)(chu)塵(chen)設備及頂部的(de)(de)部件。包括板(ban)、振打裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)、上(shang)下(xia)框架、整流(liu)變壓器、多孔板(ban)和(he)頂部蓋板(ban)等,通(tong)常只留下(xia)一個(ge)空殼。安裝(zhuang)(zhuang)(zhuang)除(chu)(chu)塵(chen)器進(jin)、出(chu)口(kou)(kou)煙(yan)(yan)道(dao)擋板(ban)閥。有些改造可能涉及到(dao)煙(yan)(yan)道(dao)和(he)除(chu)(chu)塵(chen)器進(jin)、出(chu)口(kou)(kou)的(de)(de)改造。對(dui)進(jin)入各室(shi)的(de)(de)煙(yan)(yan)氣(qi)量要(yao)(yao)計算,并(bing)進(jin)行氣(qi)流(liu)分布實驗,各室(shi)的(de)(de)氣(qi)流(liu)相對(dui)均勻。在除(chu)(chu)塵(chen)設備殼安裝(zhuang)(zhuang)(zhuang)煙(yan)(yan)氣(qi)導(dao)流(liu)板(ban)和(he)氣(qi)流(liu)均布裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)。導(dao)流(liu)板(ban)的(de)(de)設計要(yao)(yao)考慮磨。
電(dian)(dian)(dian)除塵(chen)(chen) 芒刺線(xian)(xian)線(xian)(xian)可以安(an)裝(zhuang)在臥式(shi)或立式(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)中,具有伏安(an)特性好(hao),對粉塵(chen)(chen)比(bi)電(dian)(dian)(dian)阻變化的(de)適(shi)應性,截止電(dian)(dian)(dian)壓(ya)比(bi)使用其它電(dian)(dian)(dian)暈線(xian)(xian)的(de)收塵(chen)(chen)器(qi)高兩萬伏以長處。電(dian)(dian)(dian)暈線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)能(neng)力的(de)好(hao)壞與(yu)電(dian)(dian)(dian)暈放(fang)(fang)電(dian)(dian)(dian)整個尖(jian)度(du)(既曲率)有關,;當電(dian)(dian)(dian)暈放(fang)(fang)電(dian)(dian)(dian)尖(jian)角有粉塵(chen)(chen)會聚(ju)時其曲率就較(jiao)小(xiao),這樣(yang)對它放(fang)(fang)電(dian)(dian)(dian)的(de)有很大的(de)影響。
安裝清灰系統。清灰系統主要包括壓縮空氣設備及管線、脈沖閥、儲氣罐、噴吹管及相關的電器元件。一般都設3種清灰裝置,電袋復合除塵器即差(cha)壓自動(dong)(dong)反吹清(qing)灰(hui)、時間繼(ji)電器自動(dong)(dong)清(qing)灰(hui)和(he)(he)手(shou)動(dong)(dong)清(qing)灰(hui)。根據濾袋(dai)的(de)使(shi)用壽命和(he)(he)積(ji)塵情況。保護(hu)系(xi)統的(de)安裝。包括旁(pang)路煙道(dao)、除塵設(she)備(bei)煙氣(qi)溫(wen)報警和(he)(he)緊急降溫(wen)裝置(zhi)。為了鍋爐(lu)(lu)點火燃油損壞(huai)濾袋(dai)而設(she)置(zhi)旁(pang)路煙道(dao)時,涉及到鍋爐(lu)(lu)與除塵器的(de)銜接和(he)(he)配合,另一個為題是煙溫(wen),大多數鍋爐(lu)(lu)的(de)世紀(ji)煙溫(wen)均過設(she)計值,有些溫(wen)幅度還較大,通過運行調試及投(tou)入(ru)吹灰(hui)器來控制。
電(dian)暈(yun)的型式有(you)(you)好多種,放(fang)電(dian)尖(jian)角(jiao)越(yue)多則電(dian)暈(yun)的也就越(yue)好,但是(shi)放(fang)電(dian)尖(jian)角(jiao)越(yue)多,制(zhi)作及安裝較(jiao)為(wei)難題.電(dian)暈(yun)線(xian)一般(ban)都(dou)接(jie)有(you)(you)高壓(ya)電(dian),需要有(you)(you)良(liang)好的絕緣(yuan)裝置,電(dian)暈(yun)線(xian)之間(jian)的間(jian)隔(ge)(ge)要適當,間(jian)隔(ge)(ge)太遠影響電(dian)暈(yun)的電(dian)流,間(jian)隔(ge)(ge)太近,電(dian)暈(yun)線(xian)間(jian)可能會產(chan)生(sheng)屏弊現象(xiang),造(zao)成電(dian)暈(yun)線(xian)表(biao)面電(dian)場強度減弱.集塵(chen)(chen)集塵(chen)(chen)的上下部(bu)都(dou)是(shi)固定的,并(bing)且集塵(chen)(chen)都(dou)是(shi)接(jie)地.一般(ban)要求粉塵(chen)(chen)易于(yu)沉(chen)(chen)降在極板(ban)上,在振(zhen)打的時(shi)候所產(chan)生(sheng)的二次揚塵(chen)(chen)少,同時(shi)還要求板(ban)較(jiao)為(wei)輕便(bian),又(you)要有(you)(you)的剛(gang)度,振(zhen)打時(shi)粉塵(chen)(chen)易于(yu)沉(chen)(chen)落又(you)不會發生(sheng)變形(xing)。
