Description
Technical field
The present invention relates to environment protection field more particularly to a kind of quick anaerobic fermentation systems of livestock and poultry liquid dung.
Background technique
A few days ago, with the growth of cultivation scale and cultivation quantity, waste discharge amount is growing therewith, and livestock and poultry cultivation is made
At odor pollution problem it is increasingly significant, thus how to handle livestock and poultry liquid dung discharge and processing problem be increasingly becoming people concern
A large focal spot.It is main that livestock and poultry feces are handled using traditional biogas project (i.e. CSTR engineering) in China, but CSTR engineering according to
So that there are construction investments is big, convenience larger by energy availability and demand relationship affect, putting into and use is disproportionate, not formed market
The problems such as convenience for changing and putting into and using is disproportionate, while traditional biogas project processing time natural pond that is long, and generating
Still contain a large amount of N, P, K in liquid, biogas residue, the standard of direct returning to farmland cannot be reached, both led to loss and the wave of nutrient
Take, there is also wastes for the potential risk of secondary environmental pollution.
Summary of the invention
The present invention long and halfway problem for the existing livestock and poultry liquid dung biogas project processing time, provides a kind of animal dung
The quick anaerobic fermentation system of water.
The technical scheme to solve the above technical problems is that a kind of quick anaerobic fermentation system of livestock and poultry liquid dung, packet
Include filtering ponds, fermentation vat and tank for sewage gas, which is characterized in that the filtering ponds are in parallel with fermentation vat, connected by partition, the filtering
Pond and fermentation vat are covered by same cover board, and the cover board is equipped with feed pipe in the filtering ponds part, are equipped in the filtering ponds
Immersible pump, the filtering ponds and fermentation bottom of pond portion and side have been coated with black film；The fermentation vat sidewall upper is equipped with discharge duct,
Middle part is equipped with several parallel flushing devices, and bottom is equipped with heating coil, the filtering bottom of pond portion and the fermentation bottom of pond portion by
Scum pipe connection, the scum pipe are fixed on the partition；The filtering ponds side wall upper part is equipped with exhaust pipe, the exhaust pipe
The other end is connect with the tank for sewage gas.
Further, the flushing device is 4-6, and each flushing device includes high-pressure pump and the ppr being attached thereto pipe, institute
Ppr pipe is stated to protrude into the fermentation vat.Flushing device can squeeze into gas in fermentation vat, utilize the impact force and recoil strength of air-flow
Livestock and poultry liquid dung broken shell solution is husky.
Further, interior between the flushing device to be equipped with one group of baffle, the height of baffle plate is lower than the fermentation vat side wall,
Bottom is equipped with logical liquid circular hole.Setting baffle can increase flushing effect, and livestock and poultry liquid dung is uniformly mixed by the logical liquid circular hole of bottom.
Further, baffle described in every group is made of two different hardboards of height.There are difference in height, the livestock and poultry liquid dung on top
It mixes also more uniform.
The scum pipe raises up 10 ° -15 ° to the fermentation vat side.Scum pipe fermentation vat side is higher than filtering ponds side,
It is more advantageous to fermentation residue reflux, bottom automatic ash ejector is realized using biogas pressure, ferments again after mixing.
The beneficial effects of the present invention are: the present invention is laid with black film, solves the problems, such as the lower infiltration of traditional bionethanation system, evade
Flushing device and baffle is arranged in the contraction situation that armored concrete is generated by temperature, humidity, solves anti-in anaerobic fermentation pond
The problem of answering material upper layer crust, fermentation vat bottom sediments solid layer of sand, the present invention is able to achieve the efficient quick place to livestock and poultry feces
Reason, Hydraulic retention time are no more than 5 days, ferment thorough and high-efficient.
