Description

Two-phase inoculation anaerobic dry fermentation device
Technical field
The utility model relates to a kind of solid anaerobic fermentation device, especially can realize continuous feeding and discharging, stablizes aerogenesis, evenly the dry fermentation device of inoculation.
Background technology
At present, known dry fermentation device is for solving anaerobic sealing problem, and the form that mainly adopts intermittent type to ferment in batches is by being provided with several same fermentation unit, solve the problem that intermittent type ferments in batches and fermentation raw material continue to produce, but can cause the instability of biogas output and biogas composition; Modes such as main in addition employing spray solve the problem of higher material of dry substance concentration and inoculum uniform contact, but need set up spawn culture and enriching apparatus.
Summary of the invention
For overcome do that fermentation adopts intermittent type to ferment in batches to be caused can not continuous feeding and discharging, aerogenesis is unstable and need increase problem such as spawn culture enriching apparatus, the utility model provides a kind of novel dry fermentation device, this device can not only continuous feeding and discharging, also can solve the problem of evenly inoculating by the two-phase inoculation measure of Digestive system backflow and revolution cloth.
The technical scheme that its technical problem that solves the utility model adopts is: two-phase inoculation anaerobic dry fermentation apparatus main body is made up of material pretreatment pool, anaerobic dry fermentation device and material-transporting system.The material pretreatment pool comprises Digestive system import, spiral stirrer and mixture outlet, and the Digestive system import is located at the treating pond bottom, and the discharging outlet is located at the middle and upper part for the treatment of pond; The anaerobic dry fermentation device comprises vertical type anaerobic fermentor tank and the revolution cloth system that is provided with material inlet, methane outlet, Digestive system outlet and the outlet of natural pond slag, material inlet and methane outlet are located at the top of fermentor tank respectively, Digestive system outlet and the outlet of natural pond slag are separately positioned on the middle and lower part of fermentor tank, and the revolution cloth system is distributed in the top of fermentor tank.The material outlet of material pretreatment pool is connected with revolution cloth system in the anaerobic dry fermentation device by material-transporting system, and the Digestive system import of material pretreatment pool is connected with Digestive system outlet in the anaerobic dry fermentation device.In the device operational process, fresh material mixes with the Digestive system that comes out that refluxes from fermentor tank, realizes direct inoculation; Mixture evenly feeds intake from the top by the revolution cloth system, under the effect of gravity, the liquid portion of bacterial classification enrichment is migration at a slow speed relatively downwards, and material is inoculated indirectly, thereby increased the probability that microorganism contacts with material greatly, reached the purpose of even inoculation.
The beneficial effects of the utility model are to realize continuous feeding and discharging and evenly inoculation easily in degradable solid organism, generation biogas; simple and reasonable; fermenting speed is fast, and the advantage that slag fertilizer efficiency high and no waste liquid in natural pond produces can satisfy the large-scale production requirement.
Description of drawings
Below in conjunction with accompanying drawing utility model is further specified.
Accompanying drawing is a principle schematic of the present utility model.
1. vertical type fermentation tank bodies among the figure, 2. material pretreatment pool, 3. Digestive system reflux, 4. pretreatment pool opening for feed, 5. spiral stirrer, 6. material-transporting system, 7. revolution cloth system, the 8. new bed of material, 9. dynamic seed layer 10. digests liquid layer, 11. natural pond slags outlets, 12. methane outlets.
Specific embodiments
In the accompanying drawings, the Digestive system in the Digestive system reflux (3) flows into material pretreatment pool (2), mixes with the fresh material that drops into from opening for feed (4), and stirs with spiral stirrer (5).Material enters revolution cloth system (7) by feed system (6), drops into fermentation tank body (1) behind uniform distribution, forms the solid-state new bed of material (1).Because the effect of discharging and gravity, original solid materials sinks in the tank body, forms dynamic seed layer (9), and liquid material is migration at a slow speed downwards, forms feed liquid layer (10).
