詳細介紹

煤粉灰烘干機

煤粉灰(hui)烘干(gan)機是煤粉經高(gao)溫(wen)燃燒(shao)后形成的(de)一(yi)種似火山灰(hui)質混合材(cai)料。

它是燃(ran)燒煤(mei)(mei)的(de)發(fa)電廠將煤(mei)(mei)磨(mo)成(cheng)(cheng)100微(wei)米(mi)以下的(de)煤(mei)(mei)粉,用預熱空氣噴入爐膛經(jing)燃(ran)燒形成(cheng)(cheng)懸(xuan)浮狀態(tai),產生混雜有大量不燃(ran)物(wu)的(de)高溫煙氣,經(jing)集塵裝置捕(bu)集就(jiu)得到(dao)了粉煤(mei)(mei)灰(hui)。粉煤(mei)(mei)灰(hui)的(de)化學組成(cheng)(cheng)與粘土(tu)質相似,主要成(cheng)(cheng)分為二氧(yang)化硅、三氧(yang)化二鋁、三氧(yang)化二鐵、氧(yang)化鈣(gai)和未燃(ran)盡碳。


工作原理

濕(shi)粉(fen)煤灰由供(gong)料(liao)(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)入三層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘(hong)干, 粉(fen)煤灰在(zai)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板(ban)下不(bu)斷(duan)抄(chao)起、散(san)落(luo)呈(cheng)(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)式實現熱(re)交換,物料(liao)(liao)(liao)(liao)移動(dong)至內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)(jin)(jin)入中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘(hong)干,物料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)(jin)(jin)(jin),呈(cheng)(cheng)進(jin)(jin)(jin)(jin)兩步退一步的(de)(de)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)方式,物料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既充分(fen)吸(xi)收內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)發(fa)的(de)(de)熱(re)量,又吸(xi)收中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)熱(re)量,同時(shi)又延(yan)長了(le)干燥(zao)(zao)時(shi)間(jian),物料(liao)(liao)(liao)(liao)在(zai)此(ci)(ci)達到干燥(zao)(zao)狀態。物料(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)一端而落(luo)入外(wai)(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),物料(liao)(liao)(liao)(liao)在(zai)外(wai)(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內呈(cheng)(cheng)矩(ju)形多回路方式行(xing)(xing)(xing)進(jin)(jin)(jin)(jin),達到干燥(zao)(zao)效果的(de)(de)物料(liao)(liao)(liao)(liao)在(zai)熱(re)風作(zuo)用下快速(su)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達到干燥(zao)(zao)效果的(de)(de)濕(shi)物料(liao)(liao)(liao)(liao)因自重而不(bu)能快速(su)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin),物料(liao)(liao)(liao)(liao)在(zai)此(ci)(ci)矩(ju)形抄(chao)板(ban)內進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)充分(fen)干燥(zao)(zao),由此(ci)(ci)達到干燥(zao)(zao)效果,完成干燥(zao)(zao)過程。


設備特點

該設備與其(qi)他干燥(zao)設備相比,生產(chan)(chan)能(neng)力大,可(ke)連續操作; 結構簡單,操作方便;故障(zhang)少,維(wei)修費用低;適用范圍(wei)廣,流體阻力小(xiao),可(ke)以用它干燥(zao)顆料(liao)狀物(wu)料(liao),對于那些附著性大的(de)物(wu)料(liao)也很有利(li);操作彈性大,生產(chan)(chan)上允許產(chan)(chan)品的(de)流量(liang)有較(jiao)大波動范圍(wei),不會(hui)影響(xiang)產(chan)(chan)品的(de)質量(liang);清(qing)掃(sao)容易(yi)。
