The system is simple in structure, improves the concentration and the yield of the product ethanol, reduces the energy consumption in later period of rectification, and is beneficial to recovering enzyme in the fermentation process, thus improving the fermentation level of the straw ethanol and reducing the production cost.
Description
Technical field
The utility model belongs to the fermentative production of ethanol technical field, is specifically related to a kind of coupling and separates fed-batch fermentation stalk alcoholic acid system.
Background technology
Along with the consumption of Nonrenewable resources such as oil, coal, utilize biomass resource to produce reproducible substitute energy and just causing global concern.Wherein, utilizing the agricultural crop straw of enormous amount is the focus of renewable energy source domain for raw material production ethanol.
Proportion is little, pipe-line transportation is difficult and mix characteristics such as inhomogeneous because stalk has, and has caused the difficulty of stalk ethanol fermentation.Common fermentation system comprises enzymolysis device and fermentor tank at present, and the stalk enzymolysis is fermentable sugar, then sugar is converted into ethanol; Independent fermentor tank is also arranged, and enzymolysis and fermentation are all carried out in fermentor tank.But existing fermentation system exists product inhibition, enzyme dosage than deficiencies such as big and difficult recovery.Therefore how to improve the ethanol content in the fermented liquid, and reduce the key that the product inhibition is a raising stalk ethanol fermentation level simultaneously.
Around how improving ethanol content, eliminating problems such as product suppresses, the recycling of realization enzyme, develop novel fermentation system, will reduce production costs and play important promoter action improving stalk ethanol fermentation level.
Summary of the invention
The purpose of this utility model is to provide a kind of coupling that can improve the ethanol yield to separate fed-batch fermentation stalk alcoholic acid system.
The utility model is by the following technical solutions:
A kind of coupling separates fed-batch fermentation stalk alcoholic acid system, comprises fermentor tank, and the discharge port of fermentor tank is connected with the opening for feed of equipment for separating liquid from solid, and the liquid exit of equipment for separating liquid from solid is connected with vacuum flasher.
The solid outlet of described equipment for separating liquid from solid is connected with fermentor tank top.
The flash gas outlet of described vacuum flasher is connected with water cooler, and the liquid exit of water cooler is connected with the ethanol collector.
The bottom liquid outlet of described vacuum flasher is connected with the top of fermentor tank by pump.
The top of described fermentor tank is provided with the feed supplement device.
Be provided with vacuum pump between described water cooler and the ethanol collector.
The mode that the utility model adopts the stalk feed supplement to combine with vacuum separation, vacuum separator is set, be used for vacuum separation ethanol, vacuum separator can reduce alcoholic acid inhibition in the fermenting process, improve product concentration of ethanol and yield, can also reduce later stage rectifying energy consumption, and help the recovery of enzyme in the fermenting process; Between fermentor tank and vacuum flasher, equipment for separating liquid from solid is set, make fermentation materials earlier through solid-liquid separation, liquid portion enters vacuum flasher and carries out flash separation ethanol, solid part behind the flash separation ethanol after remaining material and the solid-liquid separation continues to return ferment tank, makes the fermentation materials in the fermenting process keep good mobility; The feed supplement device that fermentor tank top is provided with is used for feed supplement in fermentor tank, thus the material concentration in the control fermentor tank and the material concentration of whole fermentation period.Of the present utility model simple in structure, can improve product concentration of ethanol and yield, can also reduce later stage rectifying energy consumption, and help the recovery of enzyme in the fermenting process, thereby improve stalk ethanol fermentation level, reduce production costs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Coupling as shown in Figure 1 separates fed-batch fermentation stalk alcoholic acid system, comprise fermentor tank 2, the top of fermentor tank 2 is provided with feed supplement device 1, the discharge port 21 of fermentor tank 2 is connected with the opening for feed 83 of equipment for separating liquid from solid 8, the solid outlet 82 of equipment for separating liquid from solid 8 is connected with fermentor tank 2 tops, the liquid exit 81 of equipment for separating liquid from solid 8 is connected with vacuum flasher 3, the flash gas of vacuum flasher 3 outlet 32 is connected with water cooler 4, the liquid exit 41 of water cooler 4 is connected with ethanol collector 6, the bottom liquid outlet 31 of vacuum flasher 3 is connected with the top of fermentor tank 2 by pump 7, is provided with vacuum pump 5 between water cooler 4 and the ethanol collector 6.
When the utility model uses, stalk raw materials ferments in fermentor tank 2, when the alcohol concn of fermentation materials in the fermentor tank 2 during greater than 3% (v/v), the material of emitting fermentor tank 2 enters equipment for separating liquid from solid 8, liquid portion after the solid-liquid separation enters vacuum flasher 3, solid part returns fermentor tank 2 and continues fermentation, open vacuum flasher 3 and vacuum pump 5, in vacuum flasher 3, carry out flash separation, ethanol after the gasification is collected in after water cooler 4 coolings and waits for next step processing in the ethanol collector 6, and the liquid of the not gasification of vacuum flasher 3 bottoms returns fermentor tank 2 by pump 7 and continues fermentation; Flash distillation is closed vacuum flasher 3 and vacuum pump 5 after finishing, and simultaneously by feed supplement device 1 feed supplement in fermentor tank 2, the control material concentration is 15%, continue fermentation, above process circulation is constantly carried out, after solid material concentration reaches 50% in fermentor tank 2, no longer carry out feed supplement, fermentation ends.
Arrow is the material trend among Fig. 1.
