Ikholamu yeMash ephindwe kabini enefuthe lenkqubo yokwahluka koxinzelelo loxinzelelo oluphindwe kabini
Isishwankathelo
Imveliso yodidi oluphindwe kabini lwenkqubo yotywala yenkqubo yotywala iquka inqaba ecolekileyo II, inqaba erhabaxa II, inqaba ecolekileyo I, nenqaba erhabaxa I. Enye inkqubo iqulethe iinqaba ezimbini ezirhabaxa, iinqaba ezimbini ezicolekileyo, kunye nenye. inqaba ingena kumphunga iinqaba ezine. Uxinzelelo oluhlukileyo phakathi kwenqaba kunye nenqaba kunye nokwahlukana kweqondo lokushisa zisetyenziselwa ukutshintshana ngokuthe ngcembe ubushushu ngokusebenzisa i-reboiler ukufezekisa injongo yokonga amandla. Emsebenzini, iinqaba ezimbini ezikrwada zondliwa ngaxeshanye, kwaye iinqaba ezimbini ezintle ngaxeshanye zithatha utywala. Okwangoku, inkqubo iye yakhuthazwa kubakhiqizi abaninzi botywala kunye ne-fuel ethanol.
Okwesithathu, iimpawu zenkqubo
1. Ukusetyenziswa kwamandla aphantsi, iitoni ze-1.2 zokusetyenziswa kotywala.
2. Umphunga omnye udlula kwi-reboiler ukufudumeza inqaba ecolekileyo II, inqaba ecolekileyo II umphunga ophezulu wewayini ufudumeza inqaba ekrwada ye-II ngokusebenzisa i-reboiler, inqaba ekrwada ye-II umphunga ophezulu wewayini ufudumeza ngqo inqaba entle I, kunye nenqaba entle I. I-Tower top wayini idlula I-reboiler ifudumeza ikholamu ekrwada I. Inqaba enye ingena kumphunga kunye neenqaba ezine ukufikelela kwiziphumo ezithathu zokudityaniswa kwe-thermal ukuzuza ukonga amandla.
3. Ukusebenzisa uxinzelelo kunye nokwahlukana kobushushu phakathi kwenqaba kunye nenqaba ukutshintshisa ubushushu ngokuthe ngcembe nge-reboiler, ubushushu bunokusetyenziswa ukuya kuthi ga kwinqanaba eliphezulu, ngaloo ndlela kugcinwa ngokufanelekileyo amandla.
Okwesine, inkqubo
Isihlanu, indlela yokufudumeza
Isitshixo ekugcinweni kwamandla kwenkqubo yindlela yokufudumala. Umphunga ophambili ushushu ngokungathanga ngqo yi-reboiler ukucoca inqaba II. Amanzi ajikisiweyo ngomphunga afudumeza kwangaphambili isivundiso sokuvubela esivuthiweyo kunye notywala obukrwada aze abuyele kwibhoyila itanki yamanzi athambileyo ukuze aphinde asetyenziswe; inqaba ecocekileyo ye-II umphunga wewayini udlula kwi-reboiler. Ikholamu ekrwada II ishushu; ikholamu entle I umphunga wewayini ufudunyezwa yi-reboiler kwikholamu ekrwada I.
Kule nkqubo, inqaba ekrwada I yinqaba yoxinzelelo olubi, inqaba erhabaxa II kunye nenqaba entle I ziinqaba zoxinzelelo lomoya, kwaye inqaba entle II yinqaba yoxinzelelo elungileyo. Umahluko woxinzelelo kunye nokwahluka kweqondo lokushisa zisetyenziselwa ukufudumeza okuhamba ngamanyathelo. Inqaba enye ingena kumphunga kunye neenqaba ezintathu ukuphumeza ukudityaniswa kwe-thermal enempembelelo emithathu ukufezekisa iinjongo zokonga amandla.
Okwesithandathu, ukuthambekela kwezinto eziphathekayo
Izigaba ezibini preheated fermentation mash kuqala ingena phezulu kwikholamu ekrwada I ukususa aldehyde, kwaye ke ukwahlula imash zibe ngamacandelo amabini ngokusebenzisa umsasazi: inxalenye enye ingena kwikholamu erhabaxa II, kwaye enye inxalenye ingena kwikholamu erhabaxa I. Emva kokuba i-mash evundisiweyo ingene kwinqaba ekrwada ye-II, ulwelo olubi luyasuswa ukusuka ezantsi kwinqaba, kwaye utywala obunzima bungena kwisohlwayo. inqaba I kufuneka igxininiswe kwaye ikhutshwe, kwaye inxalenye yotywala obugqityiweyo ikhutshwe kumgca wecala eliphezulu.
Emva komzantsi wenqaba ecocekileyo ndikhanyisa iwayini kunye nenqaba ekrwada I top wine vapor condensate, ingena kwinqaba ecolekileyo II, igxininise kwaye isuse kwinqaba ecolekileyo II, kwaye ikhuphe utywala obugqityiweyo kumgca wecala eliphezulu, kunye nokungcola okuphezulu kweqondo lokubilisa okufana ne-oyile yefuseli Thatha kwindawo esezantsi yenqaba entle II.
Isixhenxe, inqanaba eliqhelekileyo lokusetyenziswa kotywala kunye netafile yokuthelekisa umgangatho
