Two, prefractionator I takes off the part mash after vapour and is pumped up the top for entering prefractionator II after vinasse preheating, will fermentation through distillation
Alcoholic constituent in wine with dregs is separated with vinasse, and vinasse are discharged outside tower, and alcoholic constituent rising enters rectifying column II, In in the form of gas phase
Distillation and concentration is carried out in rectifying column II, in auxiliary condenser to extract despumation in the form of foreshot, in the upper side line drawing of tower
Finished product ordinary alcohol, to extract the faints concentration of the size control tower bottom of finished wine essence amount, tower bottom light wine is pumped up into wine
Head recovery tower, the alcohol steam at II top of rectifying column, gives prefractionator I heat supply, the heat source of prefractionator II and rectifying column II by reboiler
The working condition of alcohol steam from rectifying column I, prefractionator II and rectifying column II is normal pressure, and the working method of reboiler is siphon
Formula, heating carrier are the waste water of rectifying column I,
Three, the charging of foreshot's recovery tower comes from the light wine of II bottom of rectifying column and the light wine of fusel oil eliminator, warp
The auxiliary cold extraction foreshot in tower is distilled, finished product ordinary alcohol is extracted in the middle and upper part of tower, extracts fusel oil at the middle part of tower and enter
Fusel oil eliminator, the light wine after separation enter back into foreshot's recovery tower through pump, and the alcohol steam at the top of foreshot's recovery tower passes through dilute
Heat source of the tower reboiler to dilution tower heat supply as dilution tower is released, the heat supply of foreshot's recovery tower uses primary steam, working condition
For positive pressure,
Four, dilution tower makes impurity in tower using impurity increased characteristics of rectifying coefficient under alcohol low concentration such as acetaldehyde
Top concentration aggregation, is removed, the charging for diluting tower is the thick wine from prefractionator I, passes through water in a manner of extracting foreshot and emptying
It washes the bottom in tower and obtains purer light wine, enter rectifying column I, dilution after being pumped up the heating of I waste water preheater of rectifying column
The heat source of tower is that the alcohol steam at the top of foreshot's recovery tower gives dilution tower heat supply by dilution tower reboiler, and working condition is normal
Pressure,
Five, I working condition of rectifying column is positive pressure, and the charging of rectifying column I is the light wine from dilution tower bottom, through distilling in tower
Middle and lower part side take-off fusel oil, the despumation in a manner of extracting foreshot and emptying in auxiliary condenser, in top of tower side
Line takes out semi-finished product alcohol and enters eparating methanol tower, further removes methanol, and waste water is discharged in the bottom of tower, preheats water scrubber light wine
Thinned water of the rear portion as dilution tower, a part are gone the carrier of prefractionator reboiler to generate Secondary-steam heating prefractionator, are remained
Remaining part is allocated as being discharged for waste water,
Six, eparating methanol tower is condensed using methanol in the increased characteristic of alcohol concentration Gao Shiqi rectifying coefficient at the top of tower
Device end is cold to remove methanol in the form of extracting foreshot, extracts top grade alcohol in the bottom of tower.The heating method of tower is to utilize dilution
The fume of tower is heated by reboiler, and the working condition for diluting tower is negative pressure,
Seven, impurity tower focuses on the foreshot of each tower, and head impurty is further concentrated to concentration, miscellaneous in the cold extraction of tower end
The higher industrial alcohol of matter content obtains the preferable alcohol of quality in tower reactor, is pumped up dilution tower such as and further purifies, improves excellent
The yield of grade alcohol, the heating of impurity tower is heated using the fume tail gas of rectifying column II, and working condition is normal pressure.
In the technical scheme, double thick and double smart towers produce the prefractionators II of alcohol, prefractionator I, rectifying column I, rectifying column II, dilute
Releasing tower, eparating methanol tower and foreshot's recovery tower is important technical characteristic, based on double thick and pair smart towers alcohol preparation facilities and side
