The operation principle of the present invention is that：
This equipment is to use steam blasting i.e. steam explosion（Steam Explosion）, it is the explosion realized using steam ejection principle
Process carries out pretreated technology to bagasse.This equipment be will infilter bagasse organization internal steam molecule instantaneous relase it is complete
Finish, so that internal steam work is converted into mechanical energy and act on bagasse histocyte interlayer, the fiber in plant cell is lignin
It bonds, under high temperature, high steam effect, cellulose crystallity improves, and the degree of polymerization declines, hemicellulose fraction degradation, wood
Quality softens, and lateral strength of connection declines, or even softening is plastic, when the material sudden pressure reduction full of steam, in hole
Gas play expansion, generate " explosion " effect, can be partially stripped lignin, and be fiber fines by raw material tearing.Present device
Steam blasting can play the role of following several respects：First, the effect of class acidic hydrolysis and thermal degradation：During steam blasting,
High-pressure hot steam enters in fibrous raw material, and penetrates into the gap inside bagasse fibre, due to the synergy of water vapour and heat
Class acid degradation and the thermal degradation of bagasse fibre raw material, lower-molecular substance dissolution are generated, fibrous polymer degree declines；Second is that class
Mechanical breaking acts on：When high steam discharges, penetrated into the hot steam molecule inside bagasse fibre in a manner of air-flow from
More closed hole high speed abrupt release comes out, and the high speed moment flowing of fibrous inside and surrounding hot steam makes fiber
Mechanical breaking to a certain extent.This fracture is not showed only as the fracture of the key in cellulose macromolecule, and reduction end group increases, fine
The destruction of the internal hydrogen bond of dimension element, is also embodied by the destruction of the destruction and partially crystallizable area of amorphous region；Third, hydrogen bond destruction：
During steam blasting, water vapour is penetrated into each hole of bagasse fibre and is formed with the part of hydroxyl on cellulose molecular chain
Hydrogen bond.High temperature, high pressure and aqueous condition can aggravate the destruction to cellulose inside hydrogen bond again simultaneously, and dissociate new hydroxyl,
Increase the adsorption capacity of bagasse.Moment pressure release explosion makes each interpore water vapour moment in bagasse be rejected to air
In, interrupt the hydrogen bond in Bagasse-cellulose.Cellulose is by rapid cooling to room temperature while intramolecular hydrogen bond is broken so that
Cellulose supramolecular structure is " frozen ", only least a portion of hydrogen bond recombination.Solvent molecule is set to be easily accessible piece interlayer in this way, and
The solvent of infiltration further carries out solvation with Bagasse-cellulose macromolecular chain, and causes the destruction of hydrogen bond in remaining molecules,
The movement for accelerating glucose ring group finally results in the complete destruction of other crystalline regions, until being completely dissolved；Fourth, structural rearrangement is made
With：Under high temperature, high pressure, Bagasse-cellulose intramolecular hydrogen bond is increased by a degree of destruction, the mobility of cellulose chain
Add, is conducive to cellulose and changes to ordered structure, meanwhile, the fracture of cellulose molecular chain makes cellulose chain be easier to rearrange.
To dissociate the feedstock into the bagasse slurry of flocculence with less energy, since this equipment had both avoided chemically treated two
Secondary pollution problem, and solve the problems, such as that current biological treatment efficiency is low, it is the biomass conversion most promising pretreatment in field
Technology.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
