粉煤灰烘干機廠家

粉煤灰烘干機是煤粉經高溫燃燒后形成的一種似火山灰質混合材料。

它是燃(ran)燒(shao)煤(mei)的(de)發電廠將煤(mei)磨成100微米以下的(de)煤(mei)粉(fen),用預熱空氣噴入爐(lu)膛經燃(ran)燒(shao)形成懸浮狀態,產生混雜有大量不燃(ran)物(wu)的(de)高溫煙氣,經集(ji)塵裝置捕集(ji)就(jiu)得到了粉(fen)煤(mei)灰。粉(fen)煤(mei)灰的(de)化(hua)(hua)學組成與粘土質相(xiang)似,主要(yao)成分為二氧化(hua)(hua)硅、三氧化(hua)(hua)二鋁、三氧化(hua)(hua)二鐵、氧化(hua)(hua)鈣和未燃(ran)盡碳。


工(gong)作原理

濕粉(fen)煤灰由供料裝(zhuang)置進(jin)(jin)(jin)(jin)入三層(ceng)(ceng)滾筒(tong)(tong)的(de)內(nei)層(ceng)(ceng),實現順流烘(hong)干(gan)(gan), 粉(fen)煤灰在(zai)內(nei)層(ceng)(ceng)的(de)抄(chao)(chao)板(ban)(ban)下不(bu)斷抄(chao)(chao)起、散(san)落(luo)呈(cheng)(cheng)螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)(jin)式(shi)(shi)實現熱(re)交換,物(wu)(wu)(wu)(wu)(wu)料移動至內(nei)層(ceng)(ceng)的(de)另(ling)一(yi)(yi)端進(jin)(jin)(jin)(jin)入中層(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料在(zai)中層(ceng)(ceng)不(bu)斷地(di)被反(fan)復揚進(jin)(jin)(jin)(jin),呈(cheng)(cheng)進(jin)(jin)(jin)(jin)兩步(bu)退一(yi)(yi)步(bu)的(de)行(xing)(xing)進(jin)(jin)(jin)(jin)方式(shi)(shi),物(wu)(wu)(wu)(wu)(wu)料在(zai)中層(ceng)(ceng)既充(chong)分(fen)吸收內(nei)層(ceng)(ceng)滾筒(tong)(tong)散(san)發的(de)熱(re)量(liang),又吸收中層(ceng)(ceng)滾筒(tong)(tong)的(de)熱(re)量(liang),同時(shi)又延長了干(gan)(gan)燥(zao)(zao)(zao)(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)(wu)料在(zai)此(ci)達到(dao)(dao)干(gan)(gan)燥(zao)(zao)(zao)(zao)狀(zhuang)態。物(wu)(wu)(wu)(wu)(wu)料行(xing)(xing)至中層(ceng)(ceng)另(ling)一(yi)(yi)端而落(luo)入外層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料在(zai)外層(ceng)(ceng)滾筒(tong)(tong)內(nei)呈(cheng)(cheng)矩(ju)形(xing)多回路方式(shi)(shi)行(xing)(xing)進(jin)(jin)(jin)(jin),達到(dao)(dao)干(gan)(gan)燥(zao)(zao)(zao)(zao)效(xiao)(xiao)果的(de)物(wu)(wu)(wu)(wu)(wu)料在(zai)熱(re)風作(zuo)用下快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)排出(chu)滾筒(tong)(tong),沒有(you)達到(dao)(dao)干(gan)(gan)燥(zao)(zao)(zao)(zao)效(xiao)(xiao)果的(de)濕物(wu)(wu)(wu)(wu)(wu)料因自重而不(bu)能快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料在(zai)此(ci)矩(ju)形(xing)抄(chao)(chao)板(ban)(ban)內(nei)進(jin)(jin)(jin)(jin)行(xing)(xing)充(chong)分(fen)干(gan)(gan)燥(zao)(zao)(zao)(zao),由此(ci)達到(dao)(dao)干(gan)(gan)燥(zao)(zao)(zao)(zao)效(xiao)(xiao)果,完成干(gan)(gan)燥(zao)(zao)(zao)(zao)過(guo)程。


設(she)備特點

該設備與(yu)其(qi)他(ta)干燥(zao)設備相比(bi),生產(chan)(chan)能力(li)大,可連(lian)續(xu)操(cao)作; 結構簡(jian)單,操(cao)作方便(bian);故障少,維(wei)修費用低;適用范(fan)圍(wei)廣,流體阻力(li)小,可以用它干燥(zao)顆料狀物(wu)料,對于那些附著性大的(de)(de)物(wu)料也很有利;操(cao)作彈性大,生產(chan)(chan)上允許產(chan)(chan)品的(de)(de)流量(liang)有較大波(bo)動(dong)范(fan)圍(wei),不會影響產(chan)(chan)品的(de)(de)質(zhi)量(liang);清掃(sao)容易。
