Ob chav Mash kem peb-txhim kho qhov sib txawv siab distillation txheej txheem
Txheej txheem cej luam
Cov txheej txheem ob-kab distillation ntawm cov txheej txheem dej cawv feem ntau yog cov pej thuam zoo II, cov pej thuam ntxhib II, cov pej thuam ua kom zoo nkauj I, thiab cov pej thuam ntxhib I. Ib qho system muaj ob lub tsev loj, ob lub tsev zoo, thiab ib qho. pej thuam nkag mus rau hauv chav plaub yees. Lub siab sib txawv ntawm tus pej thuam thiab tus pej thuam thiab qhov sib txawv ntawm qhov kub thiab txias yog siv los maj mam pauv cov cua sov los ntawm reboiler kom ua tiav lub hom phiaj ntawm kev txuag hluav taws xob. Hauv kev ua haujlwm, ob lub tuam tsev crude yog noj ib txhij, thiab ob lub tsev zoo tib yam siv cawv. Tam sim no, cov txheej txheem tau raug txhawb nqa hauv ntau lub tuam txhab cawv thiab roj ethanol.
Thib peb, cov yam ntxwv ntawm cov txheej txheem
1. Tsawg zog noj, 1.2 tons ntawm cawv haus.
2. Ib lub zog dhau los ntawm lub reboiler kom sov cov pej thuam zoo II, cov pej thuam zoo II sab saum toj cawv vapor heats lub crude ntauwd II los ntawm lub reboiler, lub crude ntauwd II sab saum toj wine vapor ncaj qha heats lub zoo pej thuam kuv, thiab lub zoo pej thuam kuv Ntauwd sab saum toj wine hla dhau Lub reboiler heats lub crude kem I. Ib tug pej thuam nkag mus rau hauv lub chav thiab plaub yees kom ua tau peb-zoo thermal coupling kom ua tau lub zog txuag.
3. Siv qhov sib txawv ntawm qhov sib txawv thiab qhov kub ntawm qhov sib txawv ntawm cov pej thuam thiab cov pej thuam kom maj mam pauv cov cua sov los ntawm cov reboiler, cov cua sov tuaj yeem siv rau qhov siab tshaj plaws, yog li txuag hluav taws xob zoo.
Plaub, txheej txheem
Tsib, cua sov txoj kev
Tus yuam sij rau kev txuag hluav taws xob ntawm cov txheej txheem yog cua sov hom. Thawj chav yog indirect rhuab los ntawm reboiler los ntxuav lub pej thuam II. Lub chav dej condensed preheats lub mature fermentation mash thiab crude cawv thiab ces rov qab mus rau lub boiler mos dej tank rau rov siv dua; lub refined ntauwd II caw vapor hla dhau lub reboiler. Lub crude kem II yog rhuab; lub zoo kem kuv caw vapor yog rhuab los ntawm lub reboiler mus rau crude kem I.
Hauv cov txheej txheem no, tus pej thuam crude I yog lub siab tsis zoo, cov pej thuam ntxhib II thiab cov pej thuam zoo kuv yog cov tsev siab hauv huab cua, thiab cov pej thuam zoo II yog lub siab zoo. Qhov sib txawv ntawm qhov sib txawv thiab qhov kub thiab txias yog siv rau cov cua sov stepwise. Ib tus pej thuam nkag mus rau hauv chav thiab peb lub yees kom ua tiav peb qhov cuam tshuam thermal coupling kom ua tiav lub hom phiaj txuag hluav taws xob.
Thib rau, cov khoom siv sib txawv
Ob-theem preheated fermentation mash ua ntej nkag mus rau sab saum toj ntawm cov crude kem kuv kom tshem tawm cov aldehyde, thiab ces faib cov mash mus rau hauv ob qhov chaw los ntawm distributor: ib feem nkag mus rau hauv coarse kem II, thiab ib feem nkag mus rau hauv coarse kem I. Tom qab cov fermented mash nkag mus rau hauv lub crude pej thuam II, cov kua phem raug tshem tawm hauv qab ntawm lub pej thuam, thiab cov dej cawv crude nkag mus rau hauv lub zoo pej thuam kuv. tau concentrated thiab tso tawm, thiab ib feem ntawm cov cawv tiav lawm yog muab tawm ntawm kab sab sauv.
Tom qab lub hauv qab ntawm lub refined pej thuam kuv teeb wine thiab crude ntauwd kuv sab saum toj wine vapor condensate, nws nkag mus rau hauv lub zoo pej thuam II, concentrates thiab tshem tawm nyob rau hauv lub zoo pej thuam II, thiab tshem tawm ib co ntawm cov tiav cawv nyob rau hauv lub sab sauv kab, thiab qhov kub kub taw tes impurities xws li roj fusel Tshem tawm ntawm sab qis ntawm cov pej thuam zoo II.
