Description
Technical field:
This utility model belongs to energy field, is specifically related to a kind of family semi continuous stalk anaerobic fermentation device.
Background technology:
With agricultural crop straw as fermentation raw material, fermentation technology substantially pulverizes, regulate C/N ratio, feed, ferment and discharging, wherein, due to straw light specific gravity and its characteristic fibrous structure so that input and output material becomes affects the key link that biogas engineering is properly functioning.Generally use and crushed stalk is smaller szie, alleviates, by means such as sprays in screw pump extruding charging, fermentation tank, the input and output material difficulty brought because of straw self physicochemical property, but pulverize as smaller szie, bringing more energy consumption, the most tiny straw dust can cause the infringement healthy to operator and there is potential safety hazard.Screw pump and spray can improve the efficiency of input and output material and alleviate the mass transfer problem brought because straw is floating, but acts on relatively limited.Collect and the difficulty of accumulating additionally, straw methane engineering there is also fermentation raw material.Straw light specific gravity, volume is big, not readily transportable.Straw was agricultural production garbage originally, if but as material collection, straw former owner rise in price randomness is bigger.Straw is combustibles, and the stacking of a large amount of concentration exists potential safety hazard, needs to pulverize, if ventilation condition is bad is easily caused dust explosion before especially feeding intake.The stalk marsh gas demonstrative project major part of government investment cannot be properly functioning because of reasons such as straw collecting cost height and accumulating difficulties, and part is not gone into operation after even building up, discarded when the problem running link not yet exposes.
Summary of the invention:
The purpose of this utility model is to overcome existing straw methane engineering input and output material difficulty, material collection and the defect of accumulating difficulty, there is provided a kind of input and output material simple for people, it is not necessary to a large amount of collections and accumulating raw material, the family semi continuous stalk anaerobic fermentation device that aerogenesis is continual and steady.
The purpose of this utility model is realized by following technical proposals.
Family of the present utility model semi continuous stalk anaerobic fermentation device, mainly it is sequentially connected with is constituted by installation for fermenting 1, appendix 3 and family fluid seal gas holder 4, it is characterized in that installation for fermenting 1 is made up of the parallel connection of multiple fermentation unit 2, fermentation unit 2 is made up of top cover 5 and fermentation vat 10, being provided with appendix interface 9 on top cover 5, top cover 5 bottom is provided with rod-shaped weight 8；Fermentation vat 10 lip is provided with tank 6, and tank 6 is corresponding with top cover 5.
In such scheme, charging and the discharge method of described fermentation unit 2 are as follows:
During charging, open top cover 5, after simply being prescinded by straw chopper, load the nylon net bag adding counterweight, straw bag is put in fermentation vat 10, then top cover 5；During discharging, the stalk fermentation residue in mesh bag directly proposes, and unnecessary biogas slurry passes through liquid pumped.
This utility model is towards plantation peasant household, and making full use of oneself straw waste that produces of peasant household is fermentation raw material, uses dispersion and the mode for the treatment of in situ, solves straw collecting, to transport and store Financial cost high and raw material is difficult to ensure problem.Whole installation for fermenting is semi continuous fermentation, ensure that stability and the persistence of whole device aerogenesis, single fermentation unit is batch fermentation technique, utilizing manpower and simple tool, open fermentation unit top cover, straw is incorporated with the nylon net bag of counterweight after chopper simply prescinds, straw bag puts into fermentation vat, realize the disposable input and output material of packed raw material, hand labor intensity Relatively centralized, the problem solving the floating and input and output material difficulty that straw causes because of doughnut structure.The recycling of straw had both solved problem of environmental pollution, agrees with and reduces waste emission at present, the overall background of built environment friendly society, compensate for again rural energy sources limited, and the short slab that price is high meets social development and rural area productive life needs.
In sum, this utility model overcome existing straw methane engineering input and output material difficulty, material collection and accumulating difficulty defect, it is provided that family semi continuous stalk anaerobic fermentation device input and output material simple, need not collect in a large number and accumulating raw material, aerogenesis is continual and steady.

Detailed description of the invention
It is described in further detail this utility model below by embodiment, but this utility model is not limited only to described embodiment.
Embodiment one
The family semi continuous stalk anaerobic fermentation device of this example is to be sequentially connected with constituted by installation for fermenting 1, appendix 3 and family fluid seal gas holder 4, installation for fermenting 1 is made up of the parallel connection of nine fermentation unit 2, fermentation unit 2 is made up of top cover 5 and fermentation vat 10, being provided with appendix interface 9 on top cover 5, top cover 5 bottom is provided with rod-shaped weight 8；Fermentation vat 10 lip is provided with tank 6, and tank 6 is corresponding with top cover 5.
Each fermentation unit 2 is long and width is 0.71m, deep 2m.
Fermentation unit 2 upper end is the open mixing structure of brick, and there is tank 6 deep for 30cm on top, corresponding with red-sludge plastic top cover 5.Red-sludge plastic top cover 5 is the square of lower ending opening, and lower end is fixed with non-corrosive metal (NCM) rod-shaped weight 8, in order to guarantee fermentation unit air-tightness under no more than 3kPa pressure.
Leave appendix interface 9 on red-sludge plastic top cover 5, nine produced biogas of fermentation unit 2 through the family fluid seal gas holder 4 that appendix 3 input pressure is 2kPa, biogas after family fluid seal gas holder 4 output dehydration, desulfurization for cooking, heating energy.
Each fermentation unit 2 of the family semi continuous stalk anaerobic fermentation device of this example is batch fermentation device, and i.e. in an anaerobism cycle (an anaerobism cycle is about 30 days, suitably can adjust according to property of raw material and fermentation temperature), an input and output material is once.During charging, open top cover 5, after simply being prescinded by straw chopper, load the nylon net bag adding counterweight, straw bag is put in fermentation vat 10, then top cover 5.During discharging, the stalk fermentation residue in mesh bag directly proposes, and unnecessary biogas slurry passes through liquid pumped.Labor intensity is little and Relatively centralized, it is to avoid the heavy operation of input and output material every day, the problem that simultaneously also avoid continuous feed mode input and output material difficulty.Fermentation unit 2 is within an anaerobism cycle, and gas production from low to high, progressively declines after reaching peak value, and for whole installation for fermenting, total gas production is the summation of nine fermentation unit 2 gas production.Although each fermentation unit 2 is in different fermentation stages, gas production is different, but after whole installation for fermenting is in steady operational status, nine different fermentations unit 2 are exactly in the different phase in anaerobism cycle, every 1/9 anaerobism cycle, gradually change the raw material of a fermentation unit 2, and so forth, whole installation for fermenting is in the state of dynamic equilibrium, and gas production is the most stable.
