Description
Technical field
The utility model belongs to ethanol complete production unit technical field, particularly a kind of alcohol production device that does not have distillation plant.
Background technology
Existing ethanol and fuel ethanol production process are: feedstock production-→ fermentation-→ distillation-→ ethanol-→ dehydration-→ dehydrated alcohol-→ alcohol fuel.Feedstock production is divided into the preparation of starchiness, molasses and fibrous material.Starchy material need carry out pre-treatment such as removal of impurities, pulverizing, ferments after the saccharification liquefaction processing again; After need diluting, molasses raw material ferments again; Fibrous material need carry out acid hydrolysis or enzymic hydrolysis is fermented then.Zymamsis comprises preparation, enlarged culturing and the industrial fermentation of distillery yeast, obtains sophisticated karusen at last.
In alcohol industry is produced, all need through distillation workshop section from the fermenting-ripening wine with dregs to finished product alcohol, distillation workshop section was divided into for two steps: the first is separated a still-process (claiming again slightly to heat up in a steamer) with alcohol and all volatile impunties from the fermenting-ripening wine with dregs.The distillatory result obtains crude alcohol and vinasse (comprising water and non-volatility impurity), and used equipment is called distillation tower (wine with dregs tower or topping still); It two is to remove impurity in the crude alcohol, further improve the process of ethanol concn, can obtain finished product and fusel wet goods byproduct, and used equipment is rectifying tower.Alcohol production all adopts continuous still battery, rectification process both at home and abroad, and this technology is divided into two tower flow processs, three-column process flow and multitower flow process again.Rectifying tower is wherein most important operating equipment, and whether its stable operation is directly connected to the height of quality product.Distillation workshop section is the workshop section of energy consumption maximum, accounts for alcohol (this moment, 95% (W) alcohol was finished product) and produces about 60% of total energy consumption.
The method of dehydrated alcohol preparation can reduce two big classes: rectification method and absorption method.Rectification method is divided into azeotropic dehydration, ion-exchange evaporation again and adds dehydration of salt method etc.The used energy consumption of this azeotropic distillation accounts for about 1/3 of whole dehydrated alcohol production process total energy consumption, and therefore this method energy consumption is too high, also has pollutant emission simultaneously.
Alcohol fuel adds denaturing agent and obtains in dehydrated alcohol.The production of fuel ethanol cost depends primarily on the height of dehydrated alcohol production energy consumption.
The utility model content
The utility model purpose is to provide the fuel ethanol production device of the low no distillation plant of a kind of energy consumption.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of alcohol production device, comprise fermentor tank, fermentor tank is the normal pressure fermentor tank, the fermentor tank material outlet is connected with the vacuum flasher material inlet by pipeline, and flasher gaseous state material outlet is connected with interchanger, vaporizer, dehydration tower by pipeline successively; The outlet of flasher liquid material is connected with fermentor tank by the pipeline that is serially connected with suction pump.
Flasher comprises that the top connects the one-level flasher of vacuum pump, one-level flasher discharge port is connected with the secondary flash vessel opening for feed by pipeline, final stage flasher gaseous state material outlet is connected with vacuum interchanger opening for feed by pipeline, and vacuum interchanger discharge port is connected with vaporizer top opening for feed; The outlet of final stage flasher liquid material is connected with fermentor tank by the pipeline that is serially connected with suction pump.
Final stage flasher bottom discharge mouth is connected with the opening for feed of described discharge port top by the pipeline that is serially connected with suction pump and interchanger.
Vaporizer bottom discharge mouth is connected with the opening for feed of described discharge port top by the pipeline that is serially connected with suction pump and interchanger.
The utility model combines normal pressure fermentor tank and the vacuum separation equipment more than the one-level, adopts while fermenting isolating method, can effectively remove the feedback inhibition of meta-bolites, improves fermentation production rate.Simultaneously, the product after separating is carried out flash distillation, the raffinate after the flash distillation turns back in the fermentor tank, enters dehydration tower after the products therefrom vaporization and dewaters and obtain target product.The used heat of sepn process is 40-70 ℃ a low-grade heat, can realize that waste heat utilizes again.Utilize the utility model to produce ethanol, can remove the maximum distillation plant of power consumption in traditional dehydrated alcohol production technique, do not need large-scale vaccum-pumping equipment, also can utilize the low grade heat energy in the ethanol production process, facility investment is little, and energy consumption is low.
The utility model can be controlled at the concentration of fermentor tank intracellular metabolite product below 4% (wt), and mash is after separator separates, and the alcohol concn of getting back in the fermentor tank is lower than 1 ‰ (wt).
The utility model is applicable to the biomass of all alcohol production raw materials, and basic material can add continuously.
