Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific implementation mode
Such as Fig. 1, a kind of pig house biogas fermentation device, including a fermentation vat 20 and multiple raising areas 10 each raise area
10 lower section is all connected to an excrement branch pipe 11, and excrement branch pipe 11 imports excrement manifold 12, and excrement manifold 12 is connected to fermentation vat 20.
The top of the fermentation vat 20 of sealing is equipped with microorganism tank 21, and its underpart is taper, and cone tip part 22 is equipped with discharging auger
23, discharging auger 23 extends to outside fermentation vat 20 is connected to discharge tube 24 again, and fermentation vat 20 is equipped with biogas discharge pipe 25.
Biogas discharge pipe 25 is connected to pressure regulating tank 31 by check valve 33, and piston apparatus is equipped in pressure regulating tank 31
32, biogas concentrate tube 38 is connected to by check valve 33, biogas concentrate tube 38 is connected to biogas and concentrates tank 30.
The study found that production biogas efficiency it is related with temperature, methane fermentating microorganism be certain temperature range into
Row metabolic activity, can be at 8-65 DEG C, and the different aerogenesis speed of temperature height are different.At 8-65 DEG C, temperature is higher, gas production rate
It is bigger, but be not linear relationship.40-50 DEG C is biogas microorganism high temperature bacterium and the movable excessive section of mesophile, they are at this
It is all less adapted in a temperature range, thus gas production rate can decline at this time.When temperature is increased to the high temperature in 53-55 DEG C of biology
Bacterium is active, and the rate for producing biogas is most fast.Biogas fermentation temperature suddenly change, has a significant effect to biogas output, and temperature jump is super
When crossing a certain range, then it can stop aerogenesis.General normal temperature fermentation temperature will not be mutated；The mild hot fermentation of centering then requires tight
Lattice control the temperature of feed liquid.Generally, a peak of aerogenesis is at 35 DEG C or so, a higher peak at 54 DEG C or so,
Because in the two optimum fermentation temperatures, by the result of two different micropopulation participation effects.The former is medium temperature
Fermentation, the latter are hot fermentation.
So fermentation vat 20 is located in the ground（Because the temperature of underground is higher）, fermentation vat 20 is interior to be equipped with temperature sensor 28,
Combustion gas heater 40 is equipped in fermentation vat 20, combustion gas heater 40 is connected to gas pipeline 36 and exhaust piping 42, gas pipeline 36
It is connected to pressure regulating tank 31 by check valve 33, gas pipeline 36 is equipped with valve 34.
In order to radiate conveniently, combustion gas heater 40 is externally provided with multiple cooling fins 41.
Its working principle is that：
It raises the excrement that area 10 generates and fermentation vat 20 is entered by excrement manifold 12, micro- life is sprayed by microorganism tank 21
Object can ferment, and the biogas of generation enters biogas discharge pipe 25.
At this point, piston apparatus 32 rises, the air pressure in pressure regulating tank 31 reduces, and the biogas in biogas discharge pipe 25 is inhaled
Enter pressure regulating tank 31；Piston apparatus 32 declines, and the air pressure in pressure regulating tank 31 increases, and the gas in the phase enters biogas concentration
Tank 30, biogas concentrate tank 30 that can carry out central gas supply.
If 28 measured temperature of temperature sensor is less than 35 DEG C, valve 34 can be opened, gas pipeline 36 generates heat to combustion gas
Device 40 supplies combustion gas, and 40 combustion heat release of combustion gas heater improves the temperature of fermentation vat 20, and gas production rate can increase, the tail gas of burning
It is discharged by exhaust piping 42.
The residue of generation is sent out by the auger 23 that discharges, then is sent by discharge tube 24 and truck is drawn to transport.
Other content participates in the prior art.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
