Description
Technical field
A kind of stalk fermentation system, more particularly to a kind of honeybee van-type stalk fermentation system are the utility model is related to, belongs to natural pond
Gas engineering field.
Background technology
Agricultural crop straw has easily floating, difficult mixing as a kind of special biogas fermentation material（Layering is serious）, knot
The features such as shell, uniform mass transfer and high-efficiency fermenting are highly detrimental in installation for fermenting.In engineer applied, there are different economy
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 efficiently 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 reach equal by substantial amounts of mechanical agitation energy consumption input
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 are on 01 16th, 2013, slanting baffle of at least three pieces arrangements for folding shape are provided with its tank body, every piece tiltedly
The bottom of plate washer is provided with sediment mouth, 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；The top of tank body is provided with feed hopper and gas outlet, the feed pipe being connected with feed hopper and returns
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
Expect that concentration is low（Ferment TS≤3%）, generally existing fermentation operation energy consumption is big, gas producing efficiency is relatively low, and anaerobic digestion gas production efficiency is low etc.
Deficiency, seriously constrain the long-term Effec-tive Function of rice straw biogas engineering.
Because rice straw is easy to the material characteristic that floats, 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 higher content of lignin, the 10%- of its dry weight is accounted for
15%, it is difficult by anaerobe catabolism without processing so that its overall flow in the reactor is poor, easily makes
Into line clogging.In addition, the floatation characteristic of rice straw, it is easily made to form scum silica frost on the surface of zymotic fluid, relative to feces of livestock and poultry
Class reactor is easier to crust, and 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, there is good technical feasibility and application prospect.However, its key issue is to improve fermentation concentration, had
The uniform mass transfer effect of realization of effect, so as to reach the purpose for improving engineering volume term rate.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 existing 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 does not meet rural area
The horizontal low present situation of Operation and Maintenance.2nd, the patent does not take into full account zymotic fluid and the mass exchange inside stalk fermentation area so that
Stalk heap block is larger, is unfavorable for the infiltration and materials exchange of zymotic fluid.In addition, the device not to the flow field inside installation for fermenting just
The effective design of row so that can not preferably realize that uniformly 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 blows 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, gravity is larger, it is necessary to larger power can just overturn stalk, and very
Hardly possible upset is uniform, therefore is extremely difficult to uniformly mix purpose.
The content of the invention
The purpose of this utility model is to overcome above mentioned problem existing for prior art, there is provided a kind of honeybee van-type stalk fermentation
System.The utility model can effectively ensure that the abundant contact of anaerobe and stalk thing, and the fermentation for improving fermentation reactor is dense
