Description
Technical field
The present invention relates to a kind of production equipment to there is the material of microcellular structure to carry out Steam explosion treatment, is biomass profit
With the crucial processing equipment of the, industry such as biochemical industry, fermented soy, fixed-end forces.
Background technology
The technological essence of steam blasting (Steam Explosion) is：The steam molecule for infiltering inside plant tissues is short
Time bursts release finishes, it is therefore an objective to is decomposed raw material by purpose with less energy.Steam explosive machine is by the raw material in container
With high steam in the range of Millisecond, airspace is suspended in the form of fried dissipate.This process not only make use of steam
High pressure potential energy, more important is making internal steam work be converted into mechanical energy, realize adiabatic expansion acting.Due to its action time
Short, energy density is high and active position is concentrated, and makes to penetrate into the stream molecule production between the macromoleculars such as cellulose and lignin
Raw powerful destructive power, sufficiently can decompose material on macromolecular level, be that base is created in the biochemical treatments such as later stage enzyme hydrolysis
Plinth condition.
Current steam explosion equipment can only be referred to as hot spraying device, and its basic model is：Filled in a pressure vessel bottom
Valve is put, realizes that pressure discharges suddenly by the quick opening of valve, thermal jet is produced and puts effect.Mainly asked existing for this pattern
Topic is：Because deflation section is much smaller relative to pressure vessel containment, and high pressure valve opening speed is limited, high steam
The pressure releasing process time length, generally 3~10 seconds, it is difficult to reach Millisecond, can not realize steam adiabatic expansion do work, drop
Low energy density, makes material degree of decomposition not high.And when vessel volume increases, valve can not equal proportion amplification, more draw
The big gap in deflation section and vessel volume, makes pressure releasing process extend further.Therefore this thermal jet mode playback produces not
Real steam explosive-crushing phenomenon.In addition, also a kind of simulate the skill of steam explosive-crushing process by the continuous extrusion way of screw rod
Art pattern, is characterized in：Solid content or material dry body are extruded by high stress and produce high temperature, should in its outlet extruding
After power disappears, material is expanded.This technical process is not to fill the pressure that can be broken out in a manner of gas penetrates into inside plant tissues
Contracting gas energy, and it is exploded in the short time and discharge, therefore do not possess the condition of " quick-fried ", can not be from molecule also without quick-fried sound
Break original cellulose macromolecule lattice in level.The result is that carrying out compression solid with huge power consumption, cellulose is not produced but
The Expected Results of preprocessing substance, the enzyme hydrolysis for the later stage help little.
The content of the invention
The invention aims to overcome the deficiency of above-mentioned prior art, there is provided one kind is completed using steam ejection principle
The instantaneous ejection type Steam explosive machine of steam blasting process.Because the passage opening of producing of the Steam explosive machine make use of steaming caused by the difference of section
Vapour launch pressure, this just overcome traditional thermal jet put technique with processing volume increase and deflation time extend the problem of, with cylinder
Body volume increases, and section difference also accordingly increases, and is consistent the ejection speed of cylinder body, is laid a good foundation for technique amplification.
The purpose of the present invention is achieved in the following ways：
The present invention includes：Outer cylinder body, inner cylinder body, receive storehouse, framework, draw gas explosion cylinder and its control system.Wherein, inner cylinder body
It is set in outer cylinder body, upper and lower side is provided with seal assembly, and periphery is provided with guide collar, can exist vertically in the case where drawing the driving of gas explosion cylinder
Slided up and down in outer cylinder body；Outer cylinder body, which is installed on, receives storehouse top, and is communicated by valve with steam-out (SO) pipeline.Outer cylinder body,
Inner cylinder body, receive storehouse, draw gas explosion cylinder and its control system to be mounted on lower portion.Outer cylinder body bottom is provided with up-small and down-big
Conical seal (contact) face flange port, inner cylinder body bottom are provided with the elastic seal assembly of expandable.Inner cylinder body circumferentially opens appropriate sky
Hole, so that the steam in inner cylinder body is externally produced with material.The course of work of instantaneous ejection type Steam explosive machine is such：
After material is added in inner cylinder body, when running up certain position by drawing gas explosion cylinder driving inner cylinder body, inner casing
The upper-lower seal compression area of body is equal, can now open steam and enter valve, steam is entered interior outer cylinder body；It is pre- when reaching
After fixed pressure permeation equilibration time, steam off enters valve, while starts quick-fried system of drawing, and driving inner cylinder body starts to transport downwards
OK；When inner cylinder body runs downwards moment, the conical seal (contact) face of the lower seal assembly of inner cylinder body along outer cylinder body bottom radially ejects,
Expand the downward compression area of inner cylinder body, trigger inner cylinder body by downward vapor pressure differential, so as to drive inner cylinder body at a high speed to
Lower sling movement, the steam in inner cylinder body are externally produced with material by the circumferential cavity of inner cylinder body, realize steam blasting process.
It is an advantage of the invention that：
1st, steam explosion deflation section of the invention is equal to container section, and it is sudden at utmost to realize outburst.Compared to thermal jet
Put deflation time in device and be limited by deflation valve and container size, deflation time of the invention and vessel volume size without
Close, be that large-scale steam explosion equipment has got through technology channel on the premise of ensureing that steam explosion effect is constant.
2nd, the present invention accelerates driving inner cylinder body by steam pressure unstability, and caused steam ejection effect energy is huge,
High-speed driving inner cylinder body is realized, its driving force is directly proportional to compression section difference above and below container, and making inner cylinder body, no matter scale of construction quality is big
It is small to be rapidly completed steam explosion opening.
3rd, due to completing explosion within the moment of Millisecond, water vapour is made to have carried out adiabatic expansion acting, by internal steam work
It is converted into mechanical energy and acts on biomass histocyte interlayer, improves blasting energy density, material is fully decomposed,
So that the steam dwell time is shortened to tens seconds by more than ten minutes, added without chemicals, not only saved steam energy consumption,
And improve the production capacity of equipment.
4th, the present invention produces process due to whole materials and completed in moment, avoids in hot spraying device first second and the tenth
Second sprays the problem of cooking level difference of material, i.e. " preceding ripe rear raw " problem, and biochemical characteristic height is provided for subsequent treatment
Unified pretreated material.Meet process consistency requirement in industrialized production.
