Operation principle of the present utility model is：
This equipment is to use steam blasting i.e. steam explosion（Steam Explosion）, realized using steam ejection principle
The technology that blast process is pre-processed to bagasse.This equipment is instantaneously to release the steam molecule for infiltering bagasse organization internal
Discharge complete, it is wood to make the fiber that internal steam work is converted into mechanical energy and acts in bagasse histocyte interlayer, plant cell
Quality is bonded, and under high temperature, high steam effect, cellulose crystallity is improved, and the degree of polymerization declines, hemicellulose fraction drop
Solution, lignin softening, horizontal strength of connection declines, or even softening is plastic, when the material sudden pressure reduction full of steam, hole
Gas play expansion in gap, produces " explosion " effect, can be partially stripped lignin, and is fiber fines by raw material tear.This practicality
The steam blasting of novel device can play following several respects effect：One is the effect of class acidic hydrolysis and thermal degradation：Steam is quick-fried
During broken, high-pressure hot steam enters in fibrous raw material, and the space penetrated into inside bagasse fibre, due to water vapour and heat
Synergy is produced under class acid degradation and the thermal degradation of bagasse fibre raw material, lower-molecular substance dissolution, fibrous polymer degree
Drop；Two be the effect of class mechanical breaking：When high steam discharges, the vapours molecule penetrated into inside bagasse fibre is with air-flow
Mode come out from compared with blind bore gap high speed abrupt release, the flowing of high speed moment of fibrous inside and surrounding vapours makes
Mechanical breaking to a certain extent occurs for fiber.This fracture is not showed only as the key fracture in cellulose macromolecule, reducing end
The destruction of hydrogen bond, is also embodied by the destruction of amorphous region and the destruction in partially crystallizable area inside base increase, cellulose；Three be hydrogen bond
Destruction：During steam blasting, water vapour penetrate into each hole of bagasse fibre in and with the portion on cellulose molecular chain
Divide hydroxyl formation hydrogen bond.High temperature, high pressure and aqueous condition can aggravate the destruction to cellulose inside hydrogen bond again simultaneously, dissociate
New hydroxyl, adds the adsorption capacity of bagasse.Moment pressure release explosion makes each interpore water vapour moment row in bagasse
Except the hydrogen bond into air, interrupted in Bagasse-cellulose.Cellulose is rapidly cooled to while intramolecular hydrogen bond is broken
Room temperature so that cellulose supramolecular structure is " frozen ", only least a portion of hydrogen bond restructuring.So it is easily accessible solvent molecule
Piece interlayer, and the solvent penetrated into further carries out solvation with Bagasse-cellulose macromolecular chain, and cause hydrogen in remaining molecules
The destruction of key, accelerates the motion of glucose ring group, finally results in the complete destruction of other crystalline regions, until being completely dissolved；Four are
Structural rearrangement is acted on：Under high temperature, high pressure, Bagasse-cellulose intramolecular hydrogen bond is by a certain degree of destruction, cellulose chain
Mobility increase, be conducive to cellulose to change to ordered structure, meanwhile, the fracture of cellulose molecular chain makes cellulose chain more
Easily rearrange.So as to dissociate the feedstock into the bagasse slurry of flocculence with less energy, because this equipment had both been avoided
Chemically treated secondary pollution problem, solves the problem of current biological treatment efficiency is low again, is that biomass conversion field most has
The preconditioning technique of prospect.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
