Ob chav Mash kem peb-qhov sib txawv qhov sib txawv qhov siab ua kom cov txheej txheem

Nqe lus piav qhia luv:

Cov txheej txheem no tsim nyog rau kev tsim cov cawv cawv thiab roj ethanol. Cov txheej txheem no tau txais lub tebchaws patent ntawm Tuam Tshoj. Nws yog txheej txheem nkaus xwb hauv ntiaj teb uas siv ob npaug-txias ntauwd peb-txheej thermal coupling distillation thev naus laus zis los tsim cov cawv thoob ntiaj teb.

Ob-kem distillation ntau lawm ntawm cov txheej txheem cawv cawv feem ntau suav nrog cov pej thuam zoo II, cov pej thuam ntxhib II, ntauwd zoo nkauj I, thiab cov pej thuam ntxhib I. Ib qhov system muaj ob lub yees ntxhib, ob lub yees zoo, thiab ib qho pej thuam nkag mus rau chav plaub lub yees. Qhov sib txawv ntawm qhov siab ntawm tus pej thuam thiab tus pej thuam thiab qhov sib txawv ntawm qhov kub tau siv los maj mam pauv cua sov los ntawm lub reboiler kom ua tiav lub hom phiaj ntawm kev txuag hluav taws xob. Hauv kev ua haujlwm, ob lub nkuaj nyoos raug pub ib txhij, thiab ob lub yees zoo ib txhij haus cawv. Tam sim no, cov txheej txheem tau txhawb nqa hauv ntau qib cawv thiab roj ethanol cov tuam txhab tsim khoom.

Thib peb, tus yam ntxwv txheej txheem

1. Tsawg zog noj, 1.2 tons haus cawv.

2. Ib lub zog dhau los ntawm lub reboiler kom sov ntauwd zoo thib ob, cov pej thuam zoo II sab saum toj cov cawv ua rau cua sov ua rau cov pej thuam nyoos II dhau los ntawm lub reboiler, cov pej thuam nyoos II sab saum toj cawv cawv ncaj qha ua kom zoo ntauwd zoo, thiab cov pej thuam zoo Kuv ntauwd sab saum toj cawv hla dhau Lub reboiler ua kom sov cov kem nyoos I. Ib tus pej thuam nkag mus rau hauv chav thiab plaub tus yees kom ua tiav peb qhov kev sib txuas ua kom sov kom ua tiav kev txuag hluav taws xob.

3. Siv qhov sib txawv ntawm qhov siab thiab qhov kub sib txawv ntawm tus pej thuam thiab tus pej thuam kom maj mam pauv cov cua sov los ntawm lub reboiler, cov cua sov tuaj yeem siv tau rau qhov siab tshaj plaws, yog li txuag lub zog.

Tsib, cua sov txoj kev

Tus yuam sij rau kev txuag hluav taws xob ntawm cov txheej txheem yog hom cua sov. Thawj lub zog yog tsis ncaj qha rhaub los ntawm lub reboiler los ntxuav lub pej thuam II. Cov dej tso rau hauv cov dej ua ntej preheats cov txiv hmab txiv ntoo fermentation mash thiab cawv cawv thiab tom qab ntawd rov qab mus rau lub rhaub dej mos muag rau siv rov qab; cov ua kom zoo nkauj ntauwd II cov cawv cawv dhau los ntawm lub reboiler. Sab nraub qaum II yog cua sov; cov kem zoo Kuv cov cawv txiv hmab ua kom sov los ntawm lub reboiler mus rau cov kem nyoos I.

Hauv cov txheej txheem no, cov pej thuam tsis zoo Kuv yog lub tsev siab tsis zoo, cov ntxhib ntauwd II thiab cov pej thuam zoo Kuv yog cov cua siab, thiab cov pej thuam zoo II yog lub tsev siab siab. Qhov sib txawv ntawm qhov siab thiab qhov sib txawv ntawm qhov kub tau siv rau cov cua sov ib qib. Ib tus pej thuam nkag mus rau chav ua pa thiab peb lub yees kom ua tiav peb qhov kev sib txuas ua kom sov kom ua tiav lub hom phiaj txuag hluav taws xob.

Thib rau, cov khoom hloov pauv

Ob-theem preheated fermentation mash ua ntej nkag mus rau sab saum toj ntawm cov nyoos kem kuv kom tshem cov aldehyde, thiab tom qab ntawd faib cov mash ua ob ntu los ntawm tus faib khoom: ib feem nkag mus rau kab lus ntxhib II, thiab lwm qhov nkag mus rau kab lus ntxhib Kuv Tom qab cov mash fermented nkag mus rau cov pej thuam crude II, cov kua tsis zoo raug tshem tawm hauv qab ntawm tus pej thuam, thiab cov cawv nyoos nkag mus rau hauv lub pej thuam zoo Kuv yuav tsum mloog zoo thiab tso tawm, thiab ib feem ntawm cov dej cawv tiav tau muab tshem tawm ntawm sab saud sab kab.

Tom qab hauv qab ntawm cov pej thuam ua kom zoo kuv lub teeb cawv txiv hmab thiab cov pej thuam crude kuv saum cov cawv ua kua ua kua, nws nkag mus rau hauv lub tsev zoo II, mloog zoo thiab tshem tawm hauv cov pej thuam zoo II, thiab tshem tawm qee cov cawv tiav hauv kab sab saud, thiab lub siab kub npau npau impurities xws li roj fusel Nqa tawm los ntawm qis dua ntawm tus pej thuam zoo II.
