An aisle 4, the long hole of the rectangle that 4 two sides of aisle are depth 2m are equipped between the group of gas pond, all methane-generating pit groups are placed in long hole；
The methane-generating pit group is made of multiple tangent round methane-generating pits 3 that misplace two-by-two, is mixed between three methane-generating pits tangent to each other
Solidifying soil component 8, the 1m above ground level of concrete component 8；The bottom of each methane-generating pit 3 is connected to feed pipe 31 and residue outlet 32, into
Expects pipe 31 and residue outlet 32 lead to 4 two sides of aisle from underground, and all feed pipes 31 and residue outlet 32 are respectively through the first valve
Door 311 and the second valve 321 are connected on three branch pipes 5, and the feed pipe 31 and residue outlet 32 of same group of methane-generating pit group both can be common
It connects on a branch pipe, can also connect on more branch pipes, all branch pipes 5 are connected to again on same root general pipeline 6, and each branch pipe 5 is all provided with
It sets in 4 side of aisle；One pump 7 is installed, third valve 61 and the 4th valve are passed through in the both ends of general pipeline 6 respectively on general pipeline 6
62 are connected in the inlet and outlet of pump 7；Pre fermentation pond 1 is connected to 7 import of pump and third valve through the 5th valve 11 by pipeline
On general pipeline 6 between door 61；Storage biogas residue pond 2 is connected between the outlet of pump 7 and the 4th valve 62 by pipeline through the 6th valve 21
General pipeline 6 on.
As shown in figure 5, methane-generating pit 3 includes biogas slurry pond 33, the air storage chamber 34 communicated with biogas slurry pond top and is fixed on gas storage
Barrier 35 inside room 34；33 inner wall of biogas slurry pond is equipped with plastic body, and 33 bottom of pond of biogas slurry pond is inverted round table, the inverted round table
The angle of bus and axis is 15 °, and residue outlet 32 connects with pool aottom center, the biogas slurry pond side wall on edge on feed pipe 31 and inverted round table
Tangent setting；34 upper end of air storage chamber for being located most closely to the methane-generating pit of 4 side of aisle is fixedly connected with push-pull rod, two neighboring storage
A connecting rod is connected between gas chamber 34；34 top of air storage chamber is connected to biogas pipe, and all biogas pipes are coupled with biogas
On branch pipe, the biogas pipe of same group of methane-generating pit group can be connect jointly on a biogas branch pipe, can also be connect on more biogas branch pipes,
All biogas branch pipes are connected to again on same root biogas general pipeline；34 top of air storage chamber is connected to rain pipe, all rain pipes
It is coupled on rainwater branch pipe, the rain pipe of same group of methane-generating pit group can be connect jointly on a rainwater branch pipe, can also be connect more

Pump, for draining.
The working principle of the present embodiment:
Good several aisle are first divided when construction of marsh gas tank to use as daily production operation, aisle requirement is straight and more long more
Good, width is advisable with facilitating personnel to operate walking；Since the present embodiment is fed using pump from pre fermentation pond, mechanism intensity
Greatly, the angle of the bus and axis at inverted round table methane-generating pit bottom can be set as 15 °, and methane-generating pit bottom top edge is the circle of a high 20cm
Ring, for generating cyclone mixing biogas slurry when feed tube and allowing biogas residue turn, when stopping material, biogas slurry rotation is slowed down, and slowly gives natural pond
One centripetal force of slag promotes pool aottom center to be discharged in storage biogas residue pond from residue outlet biogas residue；Concrete component is first is that be used to occupy
Space does not allow generated biogas leakage to pollute；Second is that playing the role of fixed air storage chamber and balance air storage chamber lifting；It walks
Road two sides can be used for installing branch pipe, biogas branch pipe and rainwater branch pipe etc..The another ground near methane-generating pit group according to production needs
Under build several pre fermentation ponds, to methane-generating pit group press in order loop cycle feed；It is heavy for biogas residue that storage biogas residue pond is built on the ground
It is transported outward behind shallow lake；The pump being mounted on general pipeline is for flowing the fluid in pipe by assigned direction.As shown in Figures 3 and 4, it is mounted on
Branch pipe on the side of every aisle is responsible for the charging of its place methane-generating pit group and slags tap, when needing to feed, the first valve of unlatching,
4th valve and the 5th valve simultaneously close off the second valve, third valve and the 6th valve, then start pump, from pre fermentation
Pond gives each methane-generating pit to be fed one by one；When needing to slag tap, the second valve, third valve and the 6th valve are opened, is closed at the
One valve, the 4th valve and the 5th valve, then start pump, are one by one transported to biogas residue from each methane-generating pit in storage biogas residue pond.
Every branch pipe to methane tank feeding or is slagged tap, fed and slagged tap one by one in order by region according to production plan in daily production
Without carrying out everyday, the period can feed and slag tap and carry out on the same day depending on specific actual conditions, first feed morning and go out again at dusk
Slag.Unavoidably when slagging tap to take the biogas slurry that discharged out of, this is left part of biogas slurry by visual actual conditions after biogas residue precipitating more
Amount is extracted into pre fermentation pond and does starter.Air storage chamber is fastened on the rod on concrete component by rope, can be played
The effect that locking air storage chamber does not allow it arbitrarily to rotate, to avoid biogas pipe and rain pipe tangled up and knotted, when each biogas is finished,
So that air storage chamber is swung back and forth by swinging push-pull rod, then drive adjacent air storage chamber to swing back and forth together by connecting rod, thus band
It moves the indoor barrier stirring dross of each gas storage and biogas slurry obscures acceleration and produces gas.Since the diameter of air storage chamber and barrier is generally 2.5
Rice or so, and weight is little, can carry out lifting maintenance by dedicated pylon.
In conclusion combined biogas pool of the invention is designed to multiple groups methane-generating pit group, pass through the machine being mounted on general pipeline
Pump can be by region in order from each branch pipe one by one to methane tank feeding and slagging tap, design science of the present invention, strong operability, manufacture
Simply, cheap, and repair it is convenient, without will must entirely place under repair as other large and medium-sized methane-generating pits.
It is pointed out that the technical concepts and features of above-described embodiment only to illustrate the invention, it is ripe its object is to allow
The personage for knowing technique cans understand the content of the present invention and implement it accordingly, and protection model of the invention can not be limited with this
It encloses.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
