The utility model has the advantages and positive effects that firstly, the organic materials can be digested fully, and the raw material utilization ratio can reach 75% and the gas generation rate can be increased by 20%; secondly, the raw material incrustation can be overcome, so as to ensure the thorough mixing of raw materials, improve the function of killing pathogenic fungi, and further avoid secondary pollution; thirdly, high mechanized degree, simple operation, convenient management and maintenance, safe and reliable use, and an operating cost reduced by 20% are achieved; and fourthly, the methane fermentation system is suitable for the digestion of various organic materials.

Description

A kind of efficient methane fermentation unit
Technical field:
The utility model belongs to a kind of biogas fermentation device, particularly a kind of efficient methane fermentation unit.
Background technology:
The biogas conduct is with a kind of renewable energy source, not only sanitation and hygiene, cheapness, and at aspects such as developing agricultural, environmental protection and comprehensive utilizations, progressively demonstrate unique advantages, be subjected to the country and people's great attention, but there is following defective in present big-and-middle-sized vertical high-concentration biogas fermentation device: 1, apparatus structure is simple, stirring technique is backward, and the monomer pool volume is little.2, crust is serious, fault is many, and the digestibility of material is below 60%, its major cause be material in fermentation unit process from raw material-semi green stock-wayward than the ripe order of grog-grog, can cause the raw material that digestion is not good about 25% to discharge.3, the microorganism of biogas fermentation and active sludge run off seriously, and the volume organic loading of digestive organ has only 2-3KgCOP/m 3/ d.4, existing processes all adopts single-stage stirring, pump stirring, propeller agitation, but does not all reach the ideal effect in the application that Da Chi holds.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of efficient methane fermentation unit is provided, and this device can make organic matter raw material be utilized fully, abolishes crust, improves gas production rate, reduces running cost.
As above design, the technical solution of the utility model is: the multistage stirring efficient methane of a kind of large-scale circulating type fermentation unit, form by inner cavity chamber and outer chamber, and it is characterized in that: the outer chamber internal classification is provided with a plurality of agitators, and the circulating type flow deflector is housed, agitator is housed in the inner cavity chamber; A plurality of Secondary Fermentation opening for feeds are set on inner chamber wall from top to bottom, the bottom is provided with slag notch, connects airway on the inside and outside chamber; On outer chamber, be provided with opening for feed and water-in.
Lightning rod is equipped with at above-mentioned outer chamber top.
Above-mentioned inner cavity chamber inwall and inner cavity chamber outside are equipped with the circulation heating device respectively, are interconnected between them.
Above-mentioned outer chamber is peripherally equipped with thermal insulation layer.
Above-mentioned circulation heating device adopts the solar heating device.
The utlity model has following advantage and positively effect:
1, owing to annular guiding device is set in outer chamber, material can be along flowing automatically around guiding device, organic matter raw material is progressively digested, there is not the organic matter raw material of complete digestion then to flow into inner cavity chamber's continuation fermentation by opening for feed, thereby make organic matter raw material handle digestion fully, raw material availability can reach 75%, improves factor of created gase 20%.
2, owing to multistage whipping appts is set, can abolish the raw material crust, make the raw material thorough mixing, improve the function of killing pathogenic bacteria, avoid secondary pollution in outer chamber.
3, mechanization degree height, simple to operate, management and easy to maintenance, safe in utilization, reliable, can reduce working cost 20%.
4, be applicable to multiple organic digestion.As organism such as ight soil such as ox, pig, chicken, horse, sheep and agricultural crop straws.
