Iinkcukacha zeMveliso

Iithegi zeMveliso

Isishwankathelo

Imveliso yodidi oluphindwe kabini lwenkqubo yotywala yenkqubo yotywala iquka inqaba ecolekileyo II, inqaba erhabaxa II, inqaba ecokisekileyo I, kunye nenqaba erhabaxa I. Enye inkqubo iqulethe iinqaba ezimbini ezirhabaxa, iinqaba ezimbini ezicokisekileyo, kunye nenye. inqaba ingena kumphunga iinqaba ezine.Uxinzelelo olwahlukileyo phakathi kwenqaba kunye nenqaba kunye nokwahluka kobushushu kusetyenziselwa ukutshintshana ngokuthe ngcembe ubushushu nge-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 epholileyo 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 ukuphumeza ukudityaniswa kwe-thermal eneziphumo ezintathu ukuphumeza 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 kwangaphambi kokuvundisela okuvuthiweyo kunye notywala obukrwada aze abuyele kwibhoyila itanki lamanzi 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 nomahluko wobushushu usetyenziselwa ukufudumeza okuhamba ngenyathelo.Inqaba enye ingena kumphunga kunye neenqaba ezintathu ukuphumeza ukudityaniswa kwe-thermal enempembelelo emithathu ukufezekisa iinjongo zokonga amandla.

Okwesithandathu, ukuthambekela kwezinto eziphathekayo

Inqanaba ezibini preheated fermentation mash kuqala ingena phezulu kwikholamu ekrwada I ukususa aldehyde, kwaye ke ukwahlula imash zibe ngamacandelo amabini ngokusebenzisa umsasazi: inxalenye ingena kwikholamu erhabaxa II, kwaye enye inxalenye ingena kwikholamu erhabaxa I. Emva kokuba i-mash evundiweyo ingene kwinqaba ekrwada ye-II, ulwelo olubi luyasuswa ukusuka ezantsi kwinqaba, kwaye utywala obukrwada bungena kwinqaba ecocekileyo ukuze kugxininiswe kwaye kukhutshwe, kwaye inxalenye yotywala obugqityiweyo ikhutshwe phezulu. umgca wecala.

Emva komzantsi wenqaba ecokisiweyo ndikhanyisa iwayini kunye nenqaba ekrwada I top vapor condensate yewayini, ingena kwinqaba ecolekileyo II, igxininise kwaye isuse kwinqaba entle II, kwaye ikhuphe utywala obugqityiweyo kumgca wecala eliphezulu, kunye nokungcola okuphezulu kweqondo lokubilisa okufana neoyile yefuseli Thatha kwindawo esezantsi yenqaba ecolekileyo II.
