Description
Technical field
The present invention relates to a kind of stalk fermentation system, more particularly to a kind of honeybee van-type stalk fermentation system and its fermentation side
Method, belongs to biogas engineering field.
Background technology
Agricultural crop straw mixes as a kind of special biogas fermentation material with easily floating, hardly possible（Layering is serious）, knot
The features such as shell, are highly detrimental to uniform mass transfer and high-efficiency fermenting in installation for fermenting.In engineer applied, different economy are occurred in that
The biogas fermentation device of input and different fermentations scale.These devices are generally by changing the material characteristic of stalk --- crush
Deng pretreatment, requirement of the existing installation for fermenting to fermentation materials characteristic is adapted to, to reach the purpose of smooth input and output material.For example,
China Patent Publication No. CN203200264U discloses a kind of efficient hybrid anaerobic fermentation device, and publication date is 09 month 2013 18
Day, including tank body, feed pipe, discharge nozzle, discharge pipeline, biogas pipe, biogas stirring pipe, tank deck stirring motor, stirrer paddle, waterpower
Deflection plate, biogas protective cover and heating coil.The core of the patent is to put into reach by substantial amounts of mechanical agitation energy consumption
The purpose of even stirring.For another example, China Patent Publication No. CN102876566A discloses a kind of upper deflector type stalk type movable type natural pond
Gas fermentation tank, publication date is on 01 16th, 2013, and it is the slanting baffle of folding shape that at least three pieces arrangements are provided with its tank body, and every piece tiltedly
The bottom of plate washer is provided with sediment mouthful, in addition to the slant block board positioned at tank body topmost, the upper end of remaining slanting baffle and tank body
Scum silica frost passage is left between inwall；Feed hopper and gas outlet are provided with the top of tank body, the feed pipe that is connected with feed hopper and are returned
Flow tube extends bottom in tank body；Tank body lower part is provided with the sediment residual cake valve below foot slanting baffle, and tank body top is provided with
Scum silica frost residual cake valve below topmost slanting baffle.The patent does not consider anaerobe and stalk material in zymotic fluid
Effectively mixing.
Above-mentioned prior art such as is required to crush stalk at the pretreatment.Cause existing stalk marsh gas continuous fermentation apparatus thing
Material concentration is low（Fermentation TS≤3%）, generally existing fermentation operation energy consumption is big, gas producing efficiency is relatively low, and anaerobic digestion gas production efficiency is low
Deficiency, seriously constrains the long-term Effec-tive Function of rice straw biogas engineering.
Due to rice straw be easy to float material characteristic, even across the pretreatment of powder state, into installation for fermenting after,
It is difficult to ensure that its uniform mass transfer.Further, since rice straw itself has content of lignin higher, the 10%- of its dry weight is accounted for
15%, it is difficult by anaerobe catabolism without treatment so that its overall flow in the reactor is poor, easily makes
Into line clogging.In addition, the floatation characteristic of rice straw, easily makes it form scum silica frost on the surface of zymotic fluid, relative to feces of livestock and poultry
Class reactor is easier crust, causes fermentation raw material to waste, while also inhibits the release of biogas.
Therefore, a kind of new anaerobic reactor for being suitable to section shape or whole strain rice straw is researched and developed, meets China's biogas engineering
Development trend, with good technical feasibility and application prospect.However, its key issue is to improve fermentation concentration, have
The uniform mass transfer effect of realization of effect, the purpose of engineering volume term rate is improved so as to reach.In China Patent No.
A kind of van-type continuous feeding and discharging anaeroic digestor is disclosed in 2011205315851, its publication date is on 07 18th, 2012.Its
The problem of presence is as follows：1st, need to set track in inside reactor, to keep the stabilization in fermentation railway carriage or compartment, the construction to fermentation system
Level requirement is higher, and high in the operation level requirement of later stage operation maintenance process, and mass transfer effect is poor, it is clear that do not meet rural area
The low present situation of Operation and Maintenance level.2nd, the patent does not take into full account the mass exchange inside zymotic fluid and stalk fermentation area so that
Stalk heap block is larger, is unfavorable for the infiltration and materials exchange of zymotic fluid.Additionally, the device not to the flow field inside installation for fermenting just
The effective design of row so that can not preferably realize that uniform initiative, fermentation blind area are more.In this case, straw are easily caused
Organic acid in stalk fermentation zone produces excessive, it is impossible to discharge in time, while the anaerobe in zymotic fluid is again less than enough
Organic matter carry out metabolism so that the gas production rate of installation for fermenting is not high.
In addition, in German straw methane engineering, there is the two-phase zymotechnique of use " garage type ", set on installation for fermenting top
Meter mouth spray, the method for the mouth that blowed floating in installation for fermenting bottom design biogas, to realize having for stalk material and fermentative microorganism
Effect contact, but such stalk soaks that rear heap block is larger, and gravity is larger, it is necessary to larger power just can overturn stalk, and very
Hardly possible upset is uniform, therefore is extremely difficult to uniformly mix purpose.
The content of the invention
It is an object of the invention to the above mentioned problem for overcoming prior art to exist, there is provided a kind of honeybee van-type stalk fermentation system
And its fermentation process.The present invention can effectively ensure that being fully contacted for anaerobe and stalk thing, improve the hair of fermentation reactor
Ferment concentration and gas producing efficiency, while prevent stalk from floating crusting, realize the smooth input and output material of material and simplify operation maintenance, and
Stalk need not be pre-processed, reduce the pretreatment of raw material operating process of stalk engineering.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of honeybee van-type stalk fermentation system, it is characterised in that：Including installation for fermenting, closure is provided with installation for fermenting, sent out

In installation for fermenting, then lift closure and coordinate with installation for fermenting water-stop, installation for fermenting is in sealed environment；Connection feed liquor
Pipeline, disconnects circulation line, and zymotic fluid is injected in installation for fermenting, and the zymotic fluid in control installation for fermenting is in maximum water level
Afterwards, water influent pipeline is disconnected, communication loop pipeline makes zymotic fluid be flowed in liquid baffling fermentation passage, and zymotic fluid is filled in fermentation
Interior formation baffling is put, zymotic fluid fully penetrates into stalk filling area, make stalk filling area anaerobic digestion methane production.
