       1、削減除(chu)(chu)(chu)塵器(qi)的(de)(de)漏(lou)風(feng)(feng)景象(xiang):(1)除(chu)(chu)(chu)塵器(qi)在制(zhi)造(zao)裝置(zhi)進程中(zhong),要(yao)嚴厲(li)執行(xing)JC/T532焊(han)(han)接規范進行(xing)焊(han)(han)接,根絕除(chu)(chu)(chu)塵器(qi)少焊(han)(han)、漏(lou)焊(han)(han)景象(xiang)。(2)除(chu)(chu)(chu)塵器(qi)的(de)(de)卸料口應(ying)采用(yong)密封功能優越的(de)(de)鎖(suo)風(feng)(feng)安裝,當前(qian)首要(yao)以氣動(dong)或(huo)電動(dong)的(de)(de)鎖(suo)風(feng)(feng)閥為主。需要(yao)時(shi),可采用(yong)雙級(ji)鎖(suo)風(feng)(feng)安裝。一臺脈(mo)沖袋(dai)式除(chu)(chu)(chu)塵器(qi)的(de)(de)漏(lou)風(feng)(feng)率應(ying)節制(zhi)在≤3%局限。   

       2、嚴厲節制(zhi)增(zeng)濕(shi)塔(ta)的(de)(de)噴(pen)水量(liang):當水泥干法(fa)線窯尾的(de)(de)冷(leng)(leng)卻安裝采用(yong)(yong)增(zeng)濕(shi)塔(ta)時,不克不及單(dan)方面追(zhui)求降(jiang)溫結(jie)果(guo)而加大噴(pen)水量(liang),必需(xu)在(zai)確保除塵器(qi)進口溫度的(de)(de)狀(zhuang)況下嚴厲節制(zhi)增(zeng)濕(shi)塔(ta)的(de)(de)噴(pen)水量(liang)。增(zeng)濕(shi)塔(ta)盡量(liang)采用(yong)(yong)優質的(de)(de)噴(pen)槍,使噴(pen)出的(de)(de)水精密平均,用(yong)(yong)起碼(ma)的(de)(de)用(yong)(yong)水量(liang)到達 佳(jia)的(de)(de)冷(leng)(leng)卻調質結(jie)果(guo)。   

       3、不(bu)(bu)變(bian)煙(yan)氣溫(wen)(wen)度(du)在(zai)(zai)較小局限(xian)內:當(dang)處置的(de)(de)煙(yan)氣溫(wen)(wen)度(du)偏(pian)(pian)高時,須(xu)立刻接(jie)納降(jiang)低(di)操作溫(wen)(wen)度(du)、放涼風(feng)等降(jiang)溫(wen)(wen)辦(ban)法;當(dang)煙(yan)氣溫(wen)(wen)度(du)偏(pian)(pian)低(di)時,須(xu)立刻接(jie)納進步操作溫(wen)(wen)度(du)等升溫(wen)(wen)辦(ban)法。使煙(yan)氣溫(wen)(wen)度(du)能不(bu)(bu)變(bian)在(zai)(zai)規則的(de)(de)局限(xian)內,確保(bao)除塵器(qi)正常不(bu)(bu)變(bian)的(de)(de)運轉電(dian)磁脈沖閥,削減結露景象。   

       4、削減脈(mo)(mo)沖噴吹氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體與(yu)除(chu)塵(chen)器(qi)內(nei)(nei)部煙氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)溫(wen)差(cha)與(yu)去濕處(chu)置(zhi):當時(shi)(shi)國內(nei)(nei)緊(jin)縮(suo)(suo)(suo)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體的(de)(de)常用的(de)(de)供(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)道(dao)路首(shou)要(yao)是:緊(jin)縮(suo)(suo)(suo)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)——儲(chu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)罐——氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan)三聯(lian)件——氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)包——電(dian)磁脈(mo)(mo)沖閥(fa)。這(zhe)種(zhong)供(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)方法具有投資(zi)少、設備簡略(lve)的(de)(de)長處(chu),然則當外界空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)溫(wen)渡(du)過(guo)(guo)(guo)低時(shi)(shi),緊(jin)縮(suo)(suo)(suo)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體處(chu)置(zhi)不充沛(pei)、易結露(lu)。當外界空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)溫(wen)渡(du)過(guo)(guo)(guo)低且空(kong)(kong)(kong)(kong)壓氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)站(zhan)間隔較遠時(shi)(shi),供(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)道(dao)路可(ke)(ke)采(cai)用:緊(jin)縮(suo)(suo)(suo)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)——儲(chu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)罐——氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan)三聯(lian)件——空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)枯燥(zao)機——空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)加熱器(qi)——氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)包(氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)包敷(fu)設保溫(wen)資(zi)料)——脈(mo)(mo)沖閥(fa)。這(zhe)種(zhong)供(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)方法去濕充沛(pei)、徹(che)底,脈(mo)(mo)沖噴吹氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體與(yu)除(chu)塵(chen)器(qi)內(nei)(nei)部煙氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)溫(wen)差(cha)小,不易發生(sheng)(sheng)結露(lu)。當空(kong)(kong)(kong)(kong)壓氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)站(zhan)間隔不遠,氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan)三聯(lian)件中(zhong)的(de)(de)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)(guo)(guo)濾器(qi)可(ke)(ke)以知足去濕需求(qiu)時(shi)(shi),只需留意(yi)將空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)(guo)(guo)濾器(qi)接(jie)近氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)包處(chu)即可(ke)(ke),因而可(ke)(ke)省去空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)枯燥(zao)器(qi)這(zhe)一環節。當溫(wen)渡(du)過(guo)(guo)(guo)低時(shi)(shi),氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)路管道(dao)、氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)包及脈(mo)(mo)沖閥(fa)都必需接(jie)納保溫(wen)辦法,避免發生(sheng)(sheng)緊(jin)縮(suo)(suo)(suo)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)冷凝和除(chu)塵(chen)器(qi)發生(sheng)(sheng)結露(lu)。   

       5、增(zeng)強除(chu)塵器(qi)的(de)隔熱(re)(re)(re)保(bao)溫(wen)辦法(fa):除(chu)塵器(qi)的(de)殼體必(bi)需(xu)接納(na)隔熱(re)(re)(re)保(bao)溫(wen)辦法(fa),除(chu)塵器(qi)的(de)保(bao)溫(wen)普通采用(yong)巖棉、硅酸鋁板、珍珠(zhu)膨(peng)脹巖等(deng)導熱(re)(re)(re)系數低,絕熱(re)(re)(re)功(gong)能(neng)好,吸水率低,耐熱(re)(re)(re)功(gong)能(neng)好的(de)保(bao)溫(wen)資(zi)(zi)料(liao)。資(zi)(zi)料(liao)的(de)導熱(re)(re)(re)系數普通不超(chao)越(yue)0.23W/m.K。保(bao)溫(wen)資(zi)(zi)料(liao)的(de)厚度應依(yi)據地點的(de)地輿地位、本(ben)地的(de)年 低溫(wen)度、年均(jun)勻(yun)溫(wen)度而(er)定,詳細(xi)可依(yi)據“節制單元熱(re)(re)(re)損掉法(fa)”的(de)核算公式核算確定。
