Description
Technical field
The present invention relates to a kind of stalk treatment process, the pre-treating process of a kind of specifically rice wheat straw solid molding fuel densification.
Background technology
Mierocrystalline cellulose is the renewable resources of quantity maximum on the earth, accounts for 35 %～50 % of plant dry weight, is the carbohydrate the widest, that content is the abundantest that distributes on the earth.For human, it is again the recyclability material of occurring in nature quantity maximum.Agricultural crop straw is the important source of agricultural organic materials, and the agricultural crop straw output in the annual whole nation can be amounted to into 660,000 tons of nitrogenous fertilizer, 9,660,000 tons of potash fertilizer, 960,000 tons of phosphate fertilizer more than 700,000,000 tons at present, is equivalent to 1/4 of national annual fertilizer amount.Yet in recent years along with social economy and growth in the living standard, the effective rate of utilization of China's stalk resource (especially in the rural area as the utilization ratio of domestic fuel) is but more and more lower.Decompose slowly because stalk is corrupt naturally, a large amount of stalks have not only been caused the great wasting of resources by on-site incineration, and burning process produces a large amount of obnoxious flavour (incomplete combustion) and flue dust, cause serious environmental to pollute, cause the common concern of the whole society.How to become " giving up " into precious, these biomass resources are made full use of, the pollution that reduces environment is a problem anxious to be solved at present.
Compare with the mineral substance fuel-based, the heat energy that stalk contained is far from, and (stalk is generally at 14～20 MJ/Kg for people imagination low like that, coal is about 18～27 MJ/Kg), and because stalk burning-point low (hydrogeneous height), sulfur-bearing low (than low tens of times of coal), ash oontent low (only be coal 10～30%), thereby theoretically stalk biomass fuel should be even more ideal, be the fuel that more cleans and do not worry forever resource problem at least.If it is be apt to add utilization,, significant undoubtedly for advocating low charcoal, resources conservation and friendly environment society now.Yet, because its density is low, transportation cost is higher, main is burning insufficient (not clean-burning in a large number volatile matter is with the flue gas loss, so actual calorific value is low), reasons such as the workload that acts as a fuel when using is big and dirty, ratio is more and more lower in actual applications to cause it.If stalk can be processed into fine and close bulk, the loss of a large amount of volatile matters when stoping burning, and make it abundant burning, not only can obviously improve heat imitates, prolong combustion time, obtain the combustion efficacy that is quite analogous to coal, and can significantly reduce the smoke pollution in when burning, and inflammable, the characteristics easily that have that coal do not have.
Yet, the high energy compression and the compact curing moulding difficult problem of stalk but are the bottlenecks of long-term fuel limitation straw utilization, especially light-weight rice and wheat stalk, not only density is low, and one deck wax is closely contained on the surface, directly machine-shaping is very high to equipment requirements, and it is carried out suitable pre-treatment, then can obviously reduce its technology difficulty.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of prior art, the pre-treating process of a kind of rice wheat straw solid molding fuel densification is provided, can effectively change the original structure composition of stalk material, keep carbon, increase cohesiveness, destroy the hydrogen bond (causing stalk to be ordered structure) in the stalk, part degraded Mierocrystalline cellulose wherein, the tight wax that the decomposing straw surface is contained becomes to be easy to machine-shaping thereby stalk is softened.
The technical scheme that the present invention solves above technical problem is:
The pre-treating process of rice wheat straw solid molding fuel densification, according to the following steps:
⑴ get the straw powder particle with the crushed stalk of weight percent moisture content≤12%;
⑵ add a spot of alkaline matter in water, be mixed with spray solution, and alkaline matter is an ammoniacal liquor or/and unslaked lime, and the amount that alkaline matter adds is the 1-2% weight percent of spray solution total amount;
⑶ be sprayed at the prepared spray solution of step ⑵ on the straw powder particle, makes the straw powder particle wetting;
⑷ insert the wetting straw powder particle of step ⑶ in the fermentation vat and fermented 8-12 hour;
⑸ add activeconstituents and stir in the straw powder particle that has fermented, activeconstituents is a Potcrate or/and saltpetre, and the amount that activeconstituents adds is the 2-3% weight percent of straw powder particle total amount.
The solution that a spot of alkaline matter of adding is mixed with in water is chemical treatment solution, chemical treatment solution is sprayed on the crushing straw, make crushing straw wetting, the minimum water molecules of these structures progressively enters into the macromolecular mass inside of stalk cellulose by infiltration, cause its original very orderly fiber hydrogen bond structure to be destroyed on a small quantity, reach the purpose of destroying hydrogen bond, it is comparatively slow to destroy the hydrogen bond process, but (high temperature in the coalification process can make liquid water become the obvious enhanced steam of seepage force for the biological treatment (cellulose-decomposing bacteria propagation) in a step and coalification technology and moulding after being, under the effect of coalification technology mesohigh, can destroy rapidly stalk cellulose inside hydrogen bond and by the ordered structure that forms, thereby reduce the difficulty of high-pressure molding) have laid a good foundation.Add a spot of alkali (as ammoniacal liquor, unslaked lime etc.), can not influence under the active prerequisite of cellulose-decomposing bacterium, obviously improve the infiltration efficient of water molecules and the destructive force of the inner hydrogen bond of cellulosic molecule, even Mierocrystalline cellulose is also had the direct degradation capability of part.
In the straw powder particle that has fermented, add activeconstituents and stir, activeconstituents be Potcrate or/and saltpetre plays the effect of ignition dope, help the sufficient combustion of later stage stalk solid molding fuel when using.
Yet,, differ to establish a capital and need take above-mentioned biochemical treatment at different stalks.For the sawdust that is easy to process, cotton stalk, corn stalk etc., may not need long biological fermentation to handle, even simple water can be processed after moistening; But for straw, especially wheat straw, (, also can obviously reduce) that biochemical treatment may be still essential to the requirement of biochemical treatment if plurality of raw materials is mixed.
Therefore, among the above step ⑵, also add domestication's oxytolerant, alkali proof Mierocrystalline cellulose decomposition tyrothricin in the spray solution, the amount that domestication's oxytolerant, alkali proof Mierocrystalline cellulose decompose the tyrothricin adding is the 0.5-1.5% weight percent of spray solution total amount.

The technical scheme that the present invention further limits is:
The pre-treating process of aforesaid rice wheat straw solid molding fuel densification, among the step ⑶, the amount that spray solution is sprayed is every kilogram of straw powder particle spray 40-80 gram.
The pre-treating process of aforesaid rice wheat straw solid molding fuel densification, among the step ⑴, the granularity of straw powder particle is 1-10 ㎜.
The pre-treating process of aforesaid rice wheat straw solid molding fuel densification, among the step ⑶, the temperature of flushing liquor is the 60-80 degree.Such temperature helps activeconstituents and Mierocrystalline cellulose and decomposes that tyrothricin is more effective to play a role.
The invention has the beneficial effects as follows: it is to adopt method simple and feasible biology, chemistry to handle stalk that stalk biochemistry of the present invention is handled, destroy the hydrogen bond (causing stalk to be ordered structure) in the stalk, part degraded Mierocrystalline cellulose wherein, the tight wax that the decomposing straw surface is contained becomes to be easy to machine-shaping thereby stalk is softened.Because biochemical treatment, especially the effect of cellulose-decomposing bacteria excretory cellulase, not only destroyed the ordered structure of original hydrogen bond in the stalk fibre and formation thereof effectively, and macromolecular Mierocrystalline cellulose is directly degraded to some extent, even the part wax also may be decomposed in the process that biological fermentation is handled, thereby the difficulty of its machine-shaping is significantly reduced.
