Description
Technical field
The present invention relates to biomass ferment and prepare the production of fuel ethanol method, relate in particular to the transformation that the alcoholic acid early pre-treatment process is produced in wherein fermenting process and infiltration evaporation coupling, belong to the alcohol fuel preparation field.
Background technology
Biomass ferment prepares the concern that alcohol fuel has caused countries in the world, wherein especially using Mierocrystalline cellulose (as the straw of farm crop) is the inexorable trend of alcohol fuel development as fermented product fermentative preparation alcohol fuel, so get through the heat subject that technological line that cellulose fermentation prepares alcohol fuel just becomes various countries scientist extensive concern.A large amount of accumulations of the meta-bolites of fermenting process (ethanol) have bigger feedback inhibition to fermenting process, and this can have a strong impact on ethanol yield.In recent years, in order to eliminate the restraining effect of product, improve fermentation efficiency, the coupled technological line is carried out in fermenting process and sepn process to be obtained paying attention to day by day, the new fermenting process of the exploitation that particularly fermenting process and infiltration evaporation sepn process is coupled becomes one of main research topic of current fermentation engineering to obtain high spirit yield.This technology is earlier infiltration evaporation alcohol permselective membrane and biological fermentation process to be coupled, and the ethanol of generation in time shifts out fermentation system, and then improves fermentation rate, and according to estimates, this technology can be raised the efficiency 15-80 doubly; Adopt water permeable membrane then, substitute traditional rectifying with the infiltration evaporation process, required energy consumption is original 10%, therefore utilizes the infiltration evaporation technology to come the ethanol of separate fermentation production can reach the purpose that reduces cost.
Wherein contain 15～40% consolidate and contain thing (xylogen of failing to ferment) in the cellulose fermentation system, this can bring serious pollution to the infiltration evaporation sepn process in downstream, in report in the past, reactant in the biological fermentation reactor will just can enter the infiltration evaporation sepn process through pre-treatment such as micro-filtrations, such technological process is the running cost height not only, industry member is difficult to accept, but also increased the possibility of microbiological contamination, both can influence the further metabolism of thalline, increased the zymic mortality ratio again, cause fermentation rate to descend, and himself also can be accompanied by serious inhibition accumulative total phenomenon, cause the fermenting process instability.Therefore, develop a kind of new pretreatment technology and just become the basis that can the coupling technique of fermenting process and infiltration evaporation sepn process trouble-free operation.
Summary of the invention
The objective of the invention is in order to reduce the technical costs of pre existing treatment process, a kind of fermentation that improves the stability etc. of fermenting process and propose and the infiltration evaporation pretreated technology of fermentation system in the production ethanol process that is coupled, with raising zymamsis yield, and the pollution of reduction infiltrating and vaporizing membrane sepn process.
Technical scheme of the present invention is: in the fermentor tank bottom design a kind of built-in filter separator the outstanding admittedly thing of fermentation system can be separated with clear liquid, the clear liquid part is at first entered an accumulator tank by negative pressure filtration, be transported to the infiltration evaporation membrane separation apparatus by transferpump then, and alleviate the obstruction of the built-in filter separator in fermentor tank bottom by the seepage remaining liquid circulation flushing of infiltration evaporation process.The tunning of fermentor tank also enters accumulator tank easily under the atmosphere of negative pressure.Technical process after the improvement is fit to and being connected of infiltration evaporation process more, increased fermenting process and the infiltration evaporation process matching degree between the two, make the contamination phenomenon of infiltration evaporation process in downstream obtain comparatively significantly improving, also make whole fermentation process more stable.
Concrete technical scheme of the present invention is:
The pretreated technology of fermentation system in a kind of fermentation and the infiltration evaporation coupling production ethanol process, it is characterized in that biomass produce ethanol in fermentation cylinder for fermentation under microbial process, when the ethanol volumetric concentration reaches 1-25% in the jar, under the effect of vacuum system, clear liquid in the fermentor tank is transported in the accumulator tank after the filtering net formula separator of fermentor tank bottom filters, by transferpump clear liquid is transported to the infiltration evaporation membrane separation apparatus, the infiltration evaporation membrane separation apparatus is under the effect of vacuum system, the ethanol that makes of having fermented in the clear liquid is adsorbed to composite membrane surface and the dissolving in the infiltration evaporation membrane separation apparatus, diffuses through the device that is condensed after the per-meate side that film enters infiltrating and vaporizing membrane then and collects and obtain spissated ethanol.The present invention is under the effect of vacuum system, and the design of the filtering net formula separator bottom fermentor tank takes outstanding admittedly thing and the clear liquid in the separate fermentation liquid, and the filtering net formula separator of fermentor tank bottom is made up of filtration medium and fixed support part.The most key in the design of filtering net formula separator is the filtration medium of choosing respective aperture according to the fermentation system of reality, and (material can be mullite, Al comprising the chip inorganic separating film
2O
3, ZrO
2, TiO
2), agglomerating porous alloy plate, husky steel plate, stainless steel filtering nets etc. have the multichannel interface on filtering net formula separator, situation according to reality, employing is oozed in liquid round-robin mode washing and filtering dielectric surface, and according to situation about stopping up, selects several roads interface for use, and regulate flow rate corresponding (0m/s-1m/s), to reduce the pollution of filtering net formula separator.
Filtering net formula separator of the present invention and infiltration evaporation process adopt same vacuum system to provide process required motivating force.Pressure when separating with infiltration evaporation during filtration is roughly 50-500Pa.
Above-mentioned infiltration evaporation membrane separation apparatus is made up of membrane module and composite membrane (saturating pure composite membrane).Wherein composite membrane (saturating pure composite membrane) is made up of supporter and the active separating layer that ethanol is had avidity that is prepared in supporting body surface.The support body material that the present invention adopts can be inorganic mullite, Al
2O
3, ZrO
2, TiO
