Description
Technical field
The invention belongs to feed arrangement technical field, more particularly, to a kind of charging dress for stalk anaerobic fermentation gas making
Put.
Background technology
With the increasingly depleted of the fossil energies such as oil, coal, hydrogen, as a kind of new renewable and clean energy resource, enjoys pass
Note.In the various preparation methods of hydrogen, Unareobic fermentation hydrogen making with energy consumption little, hydrogen-producing speed is fast, stability is high, can profit
With substrate spectrum wide the features such as receive much concern.The substrate of Hydrogen Bio-production By Anaerobic Fermentation institute is mostly soluble sugar, shallow lake at present
Powder and its corresponding organic wastewater.China is large agricultural country, and the yield of agricultural crop straw is very big, not only environment is brought huge
Big pressure, and utilization ratio is relatively low, and a large amount of straws are not rationally utilized, and can carry out anaerobic fermentation product using straw
Raw hydrogen, it has considerable economic benefit and environmental benefit.Existing laboratory stalk anaerobic fermentation hydrogen making achieved with
Notable achievement, however substantial amounts of prepare hydrogen during encounter difficulty, be embodied in: existing stalk anaerobic fermentation
Gas maker is based on liquid feed, when with straw for substrate, because stalk fibre light specific gravity, pliability are strong, existing
Device can only introduce anti-lead device the liquid part in charging in charging, and straw hardly enters reactor in itself, and easily
Result in blockage, in the case of difficult feed, reactor discharging equally can be made difficult, so greatly reduce the product of stalk fermentation
Hydrogen amount, has had a strong impact on the production efficiency of enterprise.
Content of the invention
Present invention aim to overcome that the deficiencies in the prior art and provide and a kind of be used for stalk anaerobic fermentation gas making
Feed arrangement.
The object of the present invention is achieved like this: a kind of feed arrangement for stalk anaerobic fermentation gas making, and its feature exists
In: feed arrangement is arranged on reactor body top, and feed arrangement includes charging aperture buffer, and in charging aperture buffer, middle part sets
It is equipped with agitator, agitator side is provided with charging aperture, at charging aperture, is provided with butterfly valve, agitator opposite side is provided with air inlet pipe
And escape pipe, wherein, air inlet pipe is passed through charging aperture buffer bottom, and charging aperture buffer top is provided with closure, closure
It is provided with sealing ring and agitator between, charging aperture buffer bottom is provided with horizontal spiral propeller, immediately below agitator
Horizontal spiral propeller on be provided with feed opening, horizontal spiral propeller discharge end is arranged on reactor body internal upper part, horizontal
Spiral propeller discharge end bottom is provided with discharging opening, horizontal spiral propeller is internally provided with spiral handspike, horizontal spiral
Propeller outer end is provided with motor.
Inside described charging aperture buffer and it is provided with abrasive rubber layer inside horizontal spiral propeller.
The tangent plane of described horizontal spiral propeller is trapezoidal.
Described horizontal spiral propeller is cone, horizontal spiral propeller top and charging aperture buffer bottom phase
Cut.
Helical blade is provided with described spiral handspike, the helical blade spacing at feed opening is more than the spiral shell of discharge outlet
Rotation blade pitgh, helical blade is tangent with abrasive rubber layer.
The present invention has following good effect: existing horizontal spiral propeller is transformed, by horizontal screw propulsion
Device is changed to trapezoidal cross-section, and that is, laterally spiral propeller cross section at material inlet is big, and discharging opening cross section is little, meanwhile, horizontal
The larger one end in section, helical blade spacing is larger, the less one end in cross section, and helical blade spacing is less, so can make
Material is very easy to enter horizontal spiral propeller, is gradually reduced with horizontal spiral propeller inner diameter, between helical blade
Away from being also gradually reduced, this structure can increase the motive force of horizontal spiral propeller, reduces clogged up with material；Laterally screw propulsion
The device inwall abrasive rubber layer tangent with helical blade, is prevented from the idle running with blade for the material, not enough or do not have in material
When having subsequent material follow-up, the material in horizontal spiral propeller is fully advanced reactor, this uneven trapezoidal horizontal spiral shell
Rotation propeller solves the problems, such as to feed incomplete, severe obstruction in straw fill process, and whole feed arrangement is capable of material
Under anaerobic environment continuous, feed completely, solve stalk anaerobic fermentation produce hydrogen scale-up continuous, stablize charging and ask
Topic, has promoted the development of Hydrogen Production in Straw Fermentation industry, has had considerable economic benefit and environmental benefit.
