Description
Technical field
The present invention relates to a kind of ethanol method for making, particularly the liquid efficient system alcohol of a kind of wild stalk leaf.
Background technology
The world today, the energy has become Major Strategic resource and the decision-making foundation of various countries' the economic and political development and competition, and combustion can become more important in Energy resources, very finite sum is easily exhausted but as reserves such as the Main Resources coal that fires energy, oil, Sweet natural gases, and the large and destructible ecotope of exploitation use cost, thereby the further strong and resource of research and utilization regenerative power stalk leaf waste resources such as wild plant Chinese silvergrass, weeds, cauline leaf widely, through retrofit fermented soy ethanol with develop new forms of energy and seem particularly important and urgent.
Summary of the invention
The objective of the invention is for the brewage shortage of wild stalk leaf liquid ethanol and energy development problem, provide that a kind of complex art is leading, the batching fermentation is simplified, practical strong easily popularizations, wild stalk leaf raw material processed, refinement liquid state fermentation, quickness and high efficiency distillation, high yield and high quality are energy-conservation, the pure combustion value height of ethanol, green safety environmental protection, overall economic efficiency and social benefit be the new technology of the efficient brew ethanol of the wild plant stalk folic acid fining-off liquid state fermentation energy particularly significantly.
The technical scheme that the present invention adopts for achieving the above object is: the liquid efficient system alcohol of a kind of wild stalk leaf, it is characterized in that, this ethanol brew method mainly is natural disposition or dryness wild plant stalk leaf to be carried out separately first or co-grinding is refined into pulpous state or powdery raw material, again according to pulpous state raw material and powdery raw material moisture content with when conditions such as ground temperatures, add in proportion the bent and water purification of plant raw material liquid fermentation alcohol and rapidly and efficiently ferment, drop into again behind the wine with dregs material fermenting-ripening and distill also appropriateness in the block high-efficiency energy-saving wine steaming equipment and blend production ethanol.
Described wild plant stalk leaf comprises natural disposition and dryness Chinese silvergrass, weeds, cauline leaf.
Blending process: 1, equipment configuration: the large-scale wild plant stalk leaf of having purchased stacks place or warehouse and ventilating and thermal insulating fermenting house and fermentor tank or pond, weighing apparatus, pulping engine, stirrer, take out pump machine, strainer, filling machine, ethanol gyrograph and special use accumulates the settings such as tank.2, the smart ferment of allotting: first by collected natural disposition and dryness Chinese silvergrass, weeds, the moisture content of cauline leaf wild plant, take 10 as basic rate, respectively by the natural disposition Chinese silvergrass, weeds, the cauline leaf ratio is 4-3: 2-3: the 2-1 weighing, and by natural disposition raw material and lime, the water purification ratio is 6-5: 2-1: the 5-4 weighing, and it is softening to place the pond to soak 13-15 angel dryness raw material robust fibre, by the dryness Chinese silvergrass, weeds, the cauline leaf ratio is 3-2: 2-1: the 2-3 weighing, and by dryness raw material and lime, the water purification ratio is 5-4: 3-2: the 6-5 weighing, and it is softening to place the pond to soak 16-18 angel dryness raw material robust fibre.Use subsequently strainer and water purification respectively that natural disposition and dryness raw material filtration and washing is clean, drop into again and carry out dispersion and fining in the pulping engine and become the pulpous state raw material, and, water purification ratio bent with alcohol in diploma raw material is 7-6: 4-3: the 8-7 weighing dropped in fermentor tank or the pond fermentation 15-17 days, per 3 days during this time with stirrer or hand mixing 1 time, fermenting-ripening when treating that the wine with dregs material all precipitates mash and becomes not good merchantable.Experiment showed, that slurry raw material sugar content is higher and fermentation is faster, and ethanol production is higher.3, efficiently distill: the wine with dregs material of fermenting-ripening is used to take out the pump machine or manually drop into seal, heat and distill in the high energy-efficient distillation plant of monomer of performance, and by high heating value distillation in early stage, in the distillation of interim calorific value homogeneous heating, the later stage basic heating principle of high heating value distillation is distilled ethanol, stops distillation when ethanol tail degree is lower than 10 °.Front middle and later periods distillation gained ethanol is mixed and measure the ethanol number of degrees with the ethanol gyrograph, be lower than 90 ° of the required number of degrees such as the gained ethanol number of degrees and can carry out again 1-2 time and distill, can obtain required ethanol.Last wort sludge is discharged from distillation plant with mash and separate with filters, the gained wort sludge can be made making sheet raw material and feed ingredient or make biogas etc., the mash that contains low ethanol can be used as again to ferment (fermentation rate and output can be higher).4, add encapsulation: take 10 as basic rate, with gained more than 90 ° ethanol use it for anything else and be 8-6: 2-3: 2-1 in ethanol and fuel oil and ignition dope, rare gas element ratio: 1-0.8 weighing and adding mixes, can obtain high value efficiently and the alcohol fuel of safety energy-conserving environment protection, the alcohol fuel that will add again pours into to seal up for safekeeping in the jar special with filling machine and can carry and utilize.
Press the 1-4 repeatable operation, can realize the purpose of high-efficiency high-quality production wild plant ethanol.
Beneficial effect: the present invention takes the complex art theory, for existing wild plant ethanol brew shortage and energy demand and development problem, and through many experiments, to have various regeneration wild plants now and make the Energy production raw material, and namely utilize the processing of the stalk folic acids such as Chinese silvergrass, weeds, cauline leaf to carry out the ferment new technology of the efficient brew ethanol energy of raw material liquid.Therefore, complex art of the present invention is leading, the batching fermentation is simplified, practical strong easily popularizations, wild stalk leaf raw material processed, refinement liquid state fermentation, quickness and high efficiency are distilled, high yield and high quality is energy-conservation, the pure combustion value height of ethanol, green safety environmental protection, and it promotes the use of great economic benefit and energy development strategic importance.
