Description

Liquid backflow two closed liquid in natural pond rise and seal the dried fermentation reactor of garage type
Technical field
The utility model relates to a kind of natural pond liquid two closed liquid dried fermentation reactor of sealing garage type that rises that refluxes, and belongs to agriculture organic solid castoff recycling field.
Background technology
The mass-producing biogas technology had caused people's very big concern in the last few years in the application of renewable energy source and field of environment protection, but running cost height, economic benefit low be the existing unsolved problem of biogas engineering always.North cold area particularly, owing to be subjected to low temperature effect, winter, the aerogenesis power consumption was big, did not almost have economic benefit and can talk.Tracing it to its cause, is that the fermentation materials dry matter content is in a liquid state between 6%～10% because existing biogas fermentation technology mainly is based on the wet method biogas technology, and need with big water gaging heating waste the energy for reaching the anaeration in normal temperature leavening temperature winter.
Its fermentation materials dry matter content of dry method biogas technology can reach 20%～40%, and it is solid-state that raw material is, and is used for biogas production, except that solid content height own can reduce the power consumption, also can utilize the aerobic intensification of material, and therefore, winter, power consumption can reduce greatly.Simultaneously, do not have natural pond liquid again and produce, its fermentation residuum can be made into fertilizer, realizes zero pollutant discharge basically.But fermentation equipment is perfect not enough in the existing dry method biogas fermentation engineering application process, has the input and output material difficulty, shortcoming such as conduct heat, mass transfer is inhomogeneous.
Based on above-mentioned situation, this patent has been researched and developed natural pond liquid two closed liquid dried fermentation reactor of sealing garage type that rises that refluxes, and emphasis has solved problems such as dry method biogas fermentation input and output material difficulty, material heat and mass difficulty.
Summary of the invention
Technical problem to be solved in the utility model is: at dry method biogas fermentation device input and output material difficulty in the prior art, and problem such as fermentation materials conducts heat, mass transfer is inhomogeneous.Provide a kind of two closed liquid of natural pond liquid backflow that are suitable for cultural solid organic waste biogas fermentations such as livestock and poultry cultivation ight soil and agricultural crop straw to rise and seal the dried fermentation reactor of garage type.
The utility model is like this design: liquid two closed liquid dried fermentation reactor of sealing garage type that rises that refluxes in a kind of natural pond is characterized in that: mainly be made of rise sealed structure, natural pond liquid reflux of biogas fermentation groove 3, flexible biogas film 6, two closed liquid; Described two closed liquid sealed structure that rises comprises C type groove 9 and the liquid pipe 2 that rises; Described natural pond liquid reflux comprises backflash 7, collecting tank 8, reflux pump 1 and shower 4.Described biogas fermentation groove 3 is provided with the C type groove 9 that two traps are closed, be pressed in the C type groove 9 flexible biogas film 6 and liquid rise the pipe 2.Described biogas fermentation groove 3 adopts the shape of three enclosure wall recording quantity, and an end face and a side are opened wide.
The invention has the beneficial effects as follows: adopt the natural pond liquid of above-mentioned design two closed liquid dried fermentation reactor of sealing garage type that rises that refluxes, the cell body of biogas fermentation groove adopts the shape of three enclosure wall recording quantity, an end face and a side are opened wide, motor vehicle and transport mixer can enter, and input and output material is with to mix fermentation materials convenient especially.Biogas fermentation groove open-mouth adopts flexible biogas film to cover, and adopts two closed liquid sealed structure that rises to seal between flexible biogas film and biogas fermentation groove body of wall, and seal operation is simple, safe and reliable.Natural pond liquid reflux evenly sprays into natural pond liquid from the material top, reclaims from the material bottom, utilizes the osmosis of liquid to solve the uneven problem of fermentation materials heat and mass.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 2 is the enlarged view of A part among Fig. 1
Among the figure: 1. reflux pump, the 2. liquid pipe that rises, 3. biogas fermentation groove, 4. shower, 5. fermentation materials, 6. flexible biogas film, 7. backflash, 8. collecting tank, 9.C type groove
Embodiment
As shown in Figure 1, liquid two closed liquid dried fermentation reactor of sealing garage type that rises that refluxes in this natural pond mainly is made of rise sealed structure, natural pond liquid reflux of biogas fermentation groove 3, flexible biogas film 6, two closed liquid; Wherein two closed liquid sealed structure that rises comprises C type groove 9 and the liquid pipe 2 that rises; Natural pond liquid reflux comprises backflash 7, collecting tank 8, reflux pump 1 and shower 4.With 80% of cubic capacity in the biogas fermentation groove is each inlet amount, fermentation materials 5 is the dried maize straw section of fresh pig dung and 10～15mm, mass ratio 2.5: 1, stir with transport mixer after the charging, carried out aerobic treatment 3～5 days, and stirred every day 2 times, when temperature reaches more than 50 ℃, add 30% left and right sides inoculum and stir, transport mixer is withdrawed from.Flexible biogas film is covered biogas fermentation groove open-mouth, and flexible biogas film 6 and the liquid pipe 2 that rises is pressed in the C type groove 9, the feeding pipe 2 topping up bodies pressurization of rising makes flexible biogas film 6 sealings cover biogas fermentation grooves 3, carry out the dry method anaerobically fermenting and produce biogas, about about 20 days of this process.The biogas that produces becomes clean fuel through dehydration, desulfurization.Residue part behind the anaerobically fermenting is used for anaerobically fermenting as inoculum, and rest part becomes the high-quality green organic fertilizer by simple aerobic treatment, perhaps sells as chemical fertilizer through processing treatment.
