Embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
A kind of energy-efficient white wine continuous distillation method, comprises the following steps:
Added by vinasse in the first still kettle, distill, the alcohol steam distilled out passes into distillation tower, is carried out condensation by the condenser group be connected with distillation tower and is refluxed;
Vinasse in first still kettle after distillation pass in after-fractionating still and again distill, and pass in the first still kettle by the alcohol steam distilled out, and enter in distillation tower by the first still kettle;
If when still-process needs to combine steaming grain, after-fractionating still vinasse out enter continuous in the 3rd still kettle steaming, until wine grain cooks again;
Part alcohol isolated in distillation tower is passed into the first reboiler evaporate, and evaporation gained steam is passed in the first still kettle, by this steam the composition being dissolved in alcohol in the first still kettle distilled in distillation tower and carry out unifying process;
Part water isolated in distillation tower is passed into the second reboiler evaporate, a certain amount of pure water can be supplemented in right amount in the second reboiler for controlling wine degree, second reboiler evaporation gained steam passes in after-fractionating still, by this steam, the alcoholic content in after-fractionating still is all distilled in the first still kettle, enter subsequently in distillation tower;
The steam at distillation tower top is back in tower through condensation group condensed liquid, and non-condensable gases is directly discharged by condenser group end.Have multilayer column plate in distillation tower, the condensation point of every layer of column plate is different, and various objectionable constituent are collected on different column plates, only objectionable constituent drainage in corresponding column plate need be discharged.Equally also can collect column plate from lactone component and drain lactone component.After the liquid drain mixing on all the other column plates, obtain raw wine.
When distilling first, in the second reboiler, add a certain amount of pure water, the mixing steam that the steam evaporated is evaporated after entering after-fractionating still enters the first still kettle and distills.The mixing steam distilled enters distillation tower, when reaching balance in distillation tower, re-using and draining part water from distillation tower and pass into the second reboiler and evaporate, draining part spirituous solution simultaneously and evaporate in the first reboiler.
Why the present invention adopts aforesaid method to carry out white liquor distilling, is because except containing except a certain amount of alcohol in Chinese liquor distiller grains, also containing compositions such as ester class, aldehydes, acids, other alcohols.The energy that these compositions have is water-soluble, and what have can only be dissolved in alcohol.The present invention adopts the part alcohol separated from distillation tower as raw material, alcohol steam is evaporated in the first reboiler, enter in the first still kettle, the composition that can be dissolved in alcohol in vinasse be all dissolved in alcohol and distill, then entering in distillation tower; Vinasse after the first still kettle distillation, after the composition being dissolved in alcohol is distilled, still containing a certain amount of alcoholic content.Steam is flashed to by being passed in the second reboiler from distillation tower isolated part water (appropriate pure water can be supplemented to regulate wine degree), and be passed into after-fractionating still, make the alcoholic content in after-fractionating still be dissolved in the water and all distill, then the alcohol steam that after-fractionating still is evaporated is passed in the first still kettle; By operation can by all vaporized alcohols in vinasse out like this, also other compositions also can be distilled, simultaneously the first still kettle and after-fractionating still are connected by e Foerderanlage and can realize continuously feeding and discharging, concrete then be when the vinasse after evaporation in the first still kettle to be sent in after-fractionating still (now, continue to add new vinasse in the first still kettle), then in after-fractionating still, carry out secondary distillation, discharge the vinasse after distillation from the outlet bottom after-fractionating still subsequently.For needing the technological process combining the vinasse steaming grain in distillation, the vinasse after after-fractionating still can being distilled and grain mixture are sent in the 3rd still kettle and are cooked.The fume be evaporated from the first still kettle passes in distillation tower, and carries out condensing reflux by condenser group to fume, and condensed fume is back in tower again, and in distillation tower, non-condensable gases is directly emptying after by condenser group.Fume is in a distillation column according to the difference of condensation point, the high concentration liquid of corresponding composition is accumulated at different column plates, harmful composition is as aldehydes, methyl alcohol and other assorted alcohols materials, from corresponding column plate, drainage is separated, lactone component also from corresponding column plate drainage separate, this process is similar to leaving out the beginning and the end of traditional technology, but, be more convenient for quantization operation more more accurate than traditional technology, finally after other column plate drainages various compositions mixing out, be raw wine, through follow-up blend allotment after be finished product white wine.
As shown in Figure 1, a kind of energy-efficient white wine continuous distillation plant, comprises the first still kettle 1, after-fractionating still 3, first reboiler 2, second reboiler 4, the 3rd still kettle 5, distillation tower 6, condenser group 7;
Wherein, the discharge port of the first still kettle is connected with the opening for feed of after-fractionating still, and the vapour outlet of the first still kettle is connected with distillation tower steam inlet;
The vapour outlet of after-fractionating still is connected with the steam inlet of the first still kettle; The discharge port of after-fractionating still is connected with the opening for feed of the 3rd still kettle;
The opening for feed of the first reboiler exports with the alcohol of distillation tower and is connected, and the discharge port of the first reboiler is connected with the steam inlet of the first still kettle;
The opening for feed of the second reboiler is connected with the water out of distillation tower, and the vapour outlet of the second reboiler is connected with the steam inlet of after-fractionating still;
Condenser group is connected with the vapour outlet at distillation tower top, and the liquid exit of condenser group is connected with the fluid inlet at distillation tower top.
Further, described condenser group is also provided with atmospheric vent 8; Described first reboiler and the second reboiler all adopt steam heating, the first reboiler and the second reboiler are equipped with steam inlet 9 and vapour coagulates water out 10; Sewage draining exit 11 is equipped with bottom described first reboiler and the second reboiler.
Can realize efficient distillation by said apparatus, concrete still-process is as preceding method, and each equipment in the present invention is basic chemical industry unit, so concrete structure does not repeat at this.
Chinese liquor distiller grains of the present invention adopts continuously feeding discharging, and still-process adopts and first uses alcohol distillation, then uses steam distillation, and adopts high efficiency distillation tower to carry out removal of impurities to fume.
By device of the present invention, can not only continuous still battery be realized, raise the efficiency, and the objectionable constituent in raw wine can be removed effectively, and save energy, healthy especially favourable to drinking person.
According to above-described embodiment, just the present invention can be realized well.What deserves to be explained is; under prerequisite based on said structure design, for solving same technical problem, even if some making on the invention are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the present invention, therefore it also should in protection scope of the present invention.
