Description

One kind comprehensively utilizing pretreated continuously cooking system for stalk

Technical field

The utility model relates to biomass material processing technique fields, specifically a kind of to comprehensively utilize for stalk Pretreated continuously cooking system.

Background technique

Currently, the continuously cooking pretreatment unit of biomass material production alcohol fuel, mainly using pulping and paper-making The general equipment horizontal continuous cooking device of industry；The technology is originated from Sweden, introduces China the 1970s, has nearly 50 so far The history in year, is still mainstream continuously cooking device at present；Steam is blocked to form the material plug of sufficient intensity, realizes continuous fortune Row not only heats material by preheating spiral machine, also to spray into the medical fluid of part heat, make into before conical material plug screw machine Material is reacted with chemicals, the mass degradations such as part low-molecular weight lignin, and material softening, density reaches 140-160kg/m3, Into material density, morphological character, filtrate component and property, the extrusion dehydration characteristic, operation in a device of material plug screw machine All there is very big difference with biomass fuel ethanol pre-treatment method in rule；Its material plug screw machine, the dehydration casing with taper, The varying pitch of taper, the screw machine main shaft for becoming outer blade diameter, becoming main shaft root diameter, stalk compression ratio are generally not less than 1:3.5, The dehydration casing and cone screw axis of taper, configuration power is high, and helical axis, casing screen frame screen cylinder and the area Liao Sai tube wall mill Damage is serious, and service life is short, and replacement frequently, not only increases cost, but also reduce production efficiency；At the area Liao Sai rear portion, it is connected with One section of diffuser is equipped with spare medical fluid inlet tube therebetween, for injecting medical fluid, the material extracted is made to absorb chemicals It carries out bulk diffusion and increases lubricating action；But increased diffuser is equally high tightness material plug, also increases power consumption； And (mixture of stalk material and water is heterogeneous medium, over dry object in the identical medium of metered volume when inlet amount fluctuation The content of material is inconsistent, and the fluctuation of this inlet amount can also generate cumulative effect), it is easy in the minimum of cone-type spiral Bore region formed siccative area, and drier zone excessively can expand rapidly, and dry and hard material and material is made to fill in screw machine screen frame screen cylinder Frictional force increases severely, and when this friction sum is greater than the motive force of feed end helical blade, material no longer moves ahead, equipment blocking, Namely so-called material skids, and can only empty the steam of entire continuous steamer, shutdown is cleared up, even if being welded with anti-skidding Item, it is also difficult to avoid, or even equipment damage accident occur；

For pulping and paper-making is industry, the area Liao Sai is too long, can also aggravate the dislocation tearing of fibrous inside, damage fiber, Lead to that intensity decline is slurried；So play closure vapor action is the combination region of feeding plug tube and two sections of diffuser；

It is appropriate to increase the area Liao Sai tightness and length for biomass processes process, cancel diffusion area under control, increases in fiber The dislocation in portion is torn, especially damage crystal region fiber, the target exactly pursued；And tightness increases, and moisture decreases, can To save steam；

So the key equipment material plug screw machine of pulping and paper-making industry continuous steamer, produces fuel in biomass material It is non-serviceable in ethyl alcohol pretreatment；

Pulping and paper-making industry boiling stalk material, by 150-175 DEG C of high temperature, steam pressure 0.6-0.85Mpa, for a long time 60-180min, large scale chemicals carry out boiling processing to material, and chemicals accounts for about the 10-18% of material, and be T-type into Expects pipe top sprays into, and the material mass dryness fraction 40-50% entered from the area Liao Sai absorbs rapidly chemical solutions, is down to material content 25% or so, concurrent biochemical reaction, under the high chemicals content state at high temperature and initial stage, reaction makes fast progress, wherein constituting The lignin of plant structure intensity largely dissolves out, and material structure intensity is collapsed, loose softening, has certain mobility, in circle It is promoted in tubular boiling pipe by the screw machine with reduced spiral blade and moves ahead and stir, until intermediate tube completes digestion process, object Material fibre concentration only has 12-15%, other substances enter black liquor in the form of dissolved matter or colloid substances, and thin phenol water is added in discharger Decompression sprays into jetting storehouse after cooling；

The helical blade of pulping and paper-making industry horizontal continuous cooking device is variable diameter varying pitch, one section of blade diameter one section big It is small, and be equipped with eccentric blade and charging is stirred, material filling coefficient 50-75%, inside pipe wall is equipped with tread plate, is suitable for object Expect content 25% or so, fibre concentration 12-15% after boiling, and is dispersed into paper pulp state, has good fluidity, medium homogeneous Slurry；

Biomass material produces alcohol fuel pretreatment process, is not added or is added a small amount of chemicals, short processing time 1-40min handles the high 0.5-3.0Mpa of steam pressure, the high 20-50% of material solid content, the absolutely not mobility in boiling pipe, During boiling processing, the macromolecular lignin dissolution for constituting plant structure intensity is few, material less degradation, although there is part half fiber Dimension element dissolution, but microstructure strength reduction is little, and most of material is still with the presence of solid heterogeneous form；Screw machine becomes The lesser section meeting stockpiling of diameter helical blade diameter, promotes the power consumption of stirring material that will also sharply increase, it is easy to There is material folding between helical blade and round boiling inside pipe wall, material folding amount is built up, and material folding section increases, and material folding tightness increases By force, cause to promote the stuck shutdown of screw machine；

Biomass material produces alcohol fuel pretreatment, has essential area with the pulping digestion process of pulping and paper-making industry Not, the physical characteristic and chemical characteristic of material are also entirely different；

So the continuous steamer of pulping and paper-making industry is in biomass material production alcohol fuel pretreatment It is non-serviceable；

Continuous steamer is unable to normal use using field in stalk biomass comprehensive, cause industrial production line without Method operates normally；Currently, the continuously cooking device that the high price that a domestic limited pilot production line uses is introduced, including the U.S. Including Europe, the cellulosic ethanol industrial production line of operation is built up in the whole world, is no more than 10 in total, is all using this Also all there is the above problem in continuously cooking device, normal boot-strap rate is generally lower than 40%, and stalk cellulose ethanol industryization is promoted It is substantially at dead state, seriously constrains the development that stalk biomass comprehensive utilizes industry；

Also a kind of material is directly loadable into tank by the way of steam-explosion jar batch process, logical steam to 0.5-3Mpa, when Between 1-10min, then rapid Open valve pressure release release realizes steam blasting, it is therefore an objective to using the heat power of steam from inside Tear broken plant cell structures, improve its specific surface area, with improve enzymatic hydrolysis can and rate；And drop hemicellulose at high temperature Solution is pentose；

This steam explosion mode, has the disadvantage that, first is that stalk material be packed into tank in be relatively stationary, biological material and What is contained inside it is unable to the moisture of convection current during heating, is all the non-conductor of heat, thermal conductivity is very poor, 1-10min's Short time heating can not make internal moisture and plant body tissue be heated to balanced apparent temperature, and what instrument was shown is only Temperature outside material, due to thermally conductive bad inside material, it may appear that apparent temperature gradient is poor, i.e. gauge pressure displays temperature pressure It is higher, but stalk internal batch temperature is lower, and the demolition effect of anticipation cannot be realized in decompression release；Second is that mass dryness fraction compared with Moisture inside high organization structure of the plant is less, cannot generate enough steam blasting power, and the physiology channel of plant absorbs Moisture needs the time to complete water suction and permeates and realize the process that profit rises, and the diffusion process that this process is molten there are also leachable, do not have The profit having had rises, the demolition effect that cannot have been realized；Third is that the hyperbaric heating of short time, the material appearance outer dimension of steam explosion It is very broken, but and it is not all that the tearing generated inside the institutional framework is broken, and the microcosmic specific surface area of material does not increase very much, right Enzyme preparation can and rate help it is little；It is a large amount of first to steam when valve opening fourth is that even if the initial spray detonation pressure power of steam-explosion jar is very high Vapour preferentially sprays, and pressure inside the tank reduces rapidly, and most of material is continuously sprayed under lower and lower pressure state, not only The high temperature that anticipation is not achieved sprays quick-fried effect, and material homogeneity is very poor, is unacceptable for big industrialized production；Five It is that this steam-explosion jar loading density is extremely difficult to 100kg/m3, steam consumption is very high, and utilization ratio of device is very low；Sixth is that the fortune of interval Line mode, the charging of frequent Open valve lead to that working efficiency is extremely low, labor intensity is very big, cannot achieve industrialized production；Seven Being the charging of frequent normal pressure can opening spurts with being brought rapidly up, and makes the frequent acute variation of pot temperature, can generate metal fatigue, easily There is safety accident；

The purpose of pretreatment, first is that making in organization structure of the plant, except the avicel cellulose part for the profit that cannot absorb water Outside, other can absorb water in the tissue and micropore that profit rises, and fully absorb moisture, increase it in conjunction with the amount of water and absorption water, plant Intracorporal moisture converts heat into kinetic energy in decompression release, and volume sharply expands, and generates blast action, and tearing plant is micro- See tissue；Second is that heating time will guarantee that thermally conductive undesirable inside plant tissues are almost the same with external temperature, make plant Physiology channel absorbs moisture, completes the molten diffusion process out of infiltration and leachable, realizes that preferably profit rises, and can be only achieved anticipation Demolition effect；Third is that pressure release time is shorter, unit time self-energy density is higher under same pressure difference, demolition effect more Good, best blast action, is that frequent, a small amount of, quick pressure release is spurted；Fourth is that reduce and prevent the thermalization occurred under high temperature Reaction is learned, prevents the generation of enzymatic hydrolysis and fermentation mortifier.

Therefore, it is necessary to comprehensively utilize the technical characteristic and material characteristic of pretreatment according to biomass material, design is new Continuously cooking system, with adapted biomass raw material comprehensive utilization pretreatment process specifications, realize continuous-stable Operation reduces power consumption and steam consumption, achievees the purpose that fast decompression spurts tearing material, and reduces to steaming in boiling pipe Steam pressure generates the influence of fluctuation.
