Abstract
The invention relates to a test device for determining parameters of steam explosion technology, belonging to physics test equipment. In the current technology mode, which realizes steam explosion through fast valve opening, long pressure release time reduces the energy density, so the material decomposition degree is low, little facilitating later enzymatic hydrolysis. The technological test bench based on the principle of cylinder explosion piston provided by the invention can finish the steam explosion within milliseconds, improving the energy density and fully decomposing the material. The technical principle of the test bench is also reflected in the design of industrial steam explosion devices, which accurately simulates the production environment for future industrialization of steam explosion and, thereby, accurately determining parameters of the steam explosion technology and providing fiber pretreatment materials for metaphase experiments of biochemical treatment such as enzymatic hydrolysis and the like. Experiments of the invention are relatively independent, creating conditions for contrast tests and final parameter determination.
Description
Technical field
The present invention relates to a kind of steam explosive-crushing technology be carried out the experimental rig that technological parameter is determined, be physical test equipment.
Background technology
The technological essence of steam explosive-crushing (Steam Explosion) is: will infilter the inner compressed sudden release of gas short time of plant tissue and finish, purpose is with less energy raw material to be decomposed by purpose.Steam explosive machine be with the raw material in the container in the scope of Millisecond, be suspended in airspace with fried form of loosing.Because its action time is short, energy density is high and concentrated, and steam molecule can be penetrated between the big molecule such as cellulose and lignin, can on big molecular level material be decomposed fully, and basic condition is created in biochemical treatments such as late enzyme hydrolysis.
The basic model of the present quick-fried technology of vapour is: at a pressure vessel bottom device valve, realize that by opening fast of valve pressure discharges suddenly, produce the quick-fried effect of vapour.The subject matter that this pattern exists is that the pressure releasing process time of high steam is long, is difficult to reach Millisecond, has reduced energy density, makes the material degree of decomposition not high.Therefore this technology mode can only spurt pattern as heat, does not produce real steam explosive-crushing phenomenon.In addition, also have a kind of technology mode of simulating the steam explosive-crushing process by the continuous extrusion way of screw rod, be characterized in: solid content or title material dry body are subjected to heavily stressed extruding and produce high temperature, and after its outlet extrusion stress disappeared, material was expanded.This technical process is not the filled compression gas energy that can break out of mode that infiltrates plant tissue inside with gas, and blast discharges in the short time to make it, therefore do not possess the condition of " quick-fried ", do not have quick-fried sound yet, can't break original cellulose macromolecule lattice from molecular level.Consequently come compression solid, but do not produce the pretreated Expected Results of cellulosic material with huge power consumption, little for the enzyme hydrolysis help in later stage.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned prior art, a kind of technique testing desk that utilizes the detonation piston principle can finish the steam explosive-crushing process in the time of Millisecond is provided.The know-why of this testing stand is embodied in the design of the quick-fried equipment of industrialization vapour too, this has just accurately simulated the production technology environment for steam explosive-crushing suitability for industrialized production in the future, thereby realize that steam explosive-crushing technology is carried out correct technological parameter to be determined, and provide the fiber pretreated feedstock for testing the mid-term of biochemical treatments such as enzyme hydrolysis.
The objective of the invention is to realize in the following manner:
The present invention includes: quick-fried core, recovery cover, steam generator, experimental bench framework, electrical system, pneumatic system, steam pipe system.Wherein, quick-fried core apparatus is inner in reclaiming cover, and quick-fried core is made up of detonation and quick-fried body piston, and detonation and quick-fried body piston are slip cooperating relationship, realize slipper seal by O type circle.Recovery cover, steam generator, electrical system, pneumatic system, steam pipe system all are installed on experimental bench framework inside.The course of work of steam explosion technique testing desk is such: earlier the explosion matter material is packed in the quick-fried body piston; When the steam generator generation reaches the steam of test requirements document pressure, open steam and enter valve, make steam enter quick-fried core; After reaching the predetermined pressure permeation equilibration time of test, steam off enters valve, starts pneumatic system simultaneously, drives quick-fried body piston, does rectilinear motion in detonation, and it is prominent quick-fried to cause inner steam.In blasting process, material is sprayed into reclaims cover, for collecting and sampling.
Advantage of the present invention is:
1, the present invention drives quick-fried body piston by pneumatic system, and the steam explosive-crushing process was finished in the time of Millisecond, has improved energy density, and material is fully decomposed.
2, the present invention can accurately control vapour detonation pressure power and dwell time, can be the quick-fried production of vapour and determines accurate technological parameter.
3, the present invention test at every turn relatively independent, noiseless mutually, for contrast test and determine that optimal processing parameter created condition.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is that the right front square shaft of one embodiment of the invention is surveyed view.
Fig. 2 is the quick-fried core full sectional view of this embodiment.
With reference to accompanying drawing, the present invention includes: quick-fried core 1, recovery cover 2, steam generator 3, experimental bench framework 4, electrical system 5, pneumatic system 6, steam pipe system 7, detonation 8, quick-fried body piston 9,0 type circle 10, steam enter valve 11.
In Fig. 1 embodiment: quick-fried core 1 is installed on and reclaims cover 2 inside, and quick-fried core 1 is by detonation 8 and quick-fried body piston 9 Form, detonation 8 is slip cooperating relationship with quick-fried body piston 9, realizes slipper seal by O type circle 10. Reclaim cover 2, steam generator 3, electrical system 5, pneumatic system 6, steam pipe system 7 all are installed on experimental bench framework 4 Inner.
The course of work of the present invention is such: the explosion matter material is packed in the quick-fried body piston 9 earlier; Work as steam generation Device 3 produces when reaching the steam of test requirements document pressure, opens steam and enters valve 11, makes steam enter quick-fried core 1; After reaching the predetermined pressure permeation equilibration time of test, steam off enters valve 11, starts simultaneously pneumatic system 6, drive quick-fried body piston 9, in detonation 8, do rectilinear motion, cause inner steam blast. In blasting process, Material is injected into and reclaims cover 2, for collecting and sampling.
The specific embodiment
QB-200 type steam explosion technique testing desk is the concrete enforcement of foregoing invention.This type testing stand is equipped with the 50KW gas steam generator, maximum working pressure (MWP) 6MPa, and 405 milliliters of each quick-fried test volumes of vapour per hour on average can be finished 20 groups of tests, and the complete quick-fried technological parameter of vapour can be provided for the quick-fried equipment of continuous vapour of suitability for industrialized production.
