Evaporation ndi crystallization teknoloji
Molasses mowa zinyalala madzi asanu zotsatira evaporation chipangizo
Mwachidule
Gwero, makhalidwe ndi kuvulaza kwa molasses mowa madzi oipa
Molasses mowa wastewater ndi mkulu-concentration ndi mkulu-mtundu organic zinyalala zotayidwa ku msonkhano mowa wa fakitale shuga kupanga mowa pambuyo nayonso mphamvu molasses. Lili ndi mapuloteni ambiri ndi zinthu zina zakuthupi, komanso lili ndi mchere wambiri monga Ca ndi Mg komanso wochuluka kwambiri. SO2 ndi zina zotero. Nthawi zambiri, pH yamadzi otayira mowa ndi 4.0-4.8, COD ndi 100,000-130,000 mg/1, BOD ndi 57-67,000 mgSs, 10.8-82.4 mg/1. Kuonjezera apo, madzi ambiri amtundu uwu ndi acidic, ndipo mtundu wake ndi wapamwamba kwambiri, wa bulauni-wakuda, makamaka kuphatikizapo mtundu wa caramel, mtundu wa phenolic, mtundu wa Maillard ndi zina zotero. Popeza madzi otayira amakhala ndi pafupifupi 10% zolimba, ndende yake ndi yochepa ndipo sangathe kugwiritsidwa ntchito. Ngati atayidwa mwachindunji m'mitsinje ndi m'minda popanda chithandizo, awononga kwambiri madzi abwino ndi chilengedwe, kapena kupangitsa nthaka kukhala acidity ndi compaction, komanso kukula kwa matenda a mbewu. Momwe mungathanirane ndi kugwiritsa ntchito madzi otayira mowa wa molasses ndi vuto lalikulu la chilengedwe lomwe makampani a shuga akukumana nawo.
Molasses mowa wotayira madzi amawononga kwambiri ndipo ali ndi chroma yambiri, yomwe imakhala yovuta kuchotsa pogwiritsa ntchito biochemical. Kuwotchera kwambiri kapena feteleza wamadzi wochuluka kwambiri ndiye njira yochizira bwino kwambiri pakadali pano.
Chipangizochi chimagwiritsa ntchito njira zisanu zokakamiza kuzungulira kutsika pansi, ndi nthunzi yodzaza ngati gwero la kutentha, kutentha kwamtundu umodzi ndi ntchito zisanu. Madzi otayira mowa wa molasses omwe ali ndi 5 mpaka 6% amakhazikika ndikusinthidwa, ndipo slurry yokhazikika yokhala ndi ≥ 60% imatumizidwa ku chotenthetsera kuti chiwotchedwe, ndipo kutentha komwe kumapangidwa kumakhutitsa nthunzi ya chipangizocho. Sungunulani madzi osungunuka kubwereranso ku gawo lapitalo kuti muchepetse madzi.
Chachiwiri, ndondomeko otaya tchati
Chachitatu, ndondomeko makhalidwe
1. Khazikitsani evaporator yopuma kuti ichotse zinthuzo, zomwe zimatha kuzindikira kuyeretsa kosalekeza ndikuwonetsetsa kupanga kosalekeza.
2. Chipangizocho chimatengera kuwongolera pulogalamu yodziwikiratu kuti ipulumutse ndalama zantchito.
3. High processing dzuwa ndi ntchito khola.
4. Pogwiritsa ntchito slurry wandiweyani kubwerera ku boiler, molasi amatha kupanga mowa popanda kuwonjezera mafuta.
5. Evaporator yopuma imayikidwa kuti iwonongeke, yomwe imatha kuzindikira kuyeretsa kosalekeza ndikuwonetsetsa kupanga kosalekeza.
6. Mowa ukhoza kupangidwa kuchokera ku molasi popanda kuwonjezera mafuta mu slurry wokhuthala kuti ugwiritsidwenso ntchito ndi ma molasi.
