Description
Technical field
The present invention relates to anaerobic fermentation technology, a kind of dress of scum silica frost in clearance curve tunnel type methane-generating pit is related in particular to
Put.
Background technology
After hydraulic type biomass pool runs a period of time, because a part of fermentation raw material and accompaniment are in the presence of buoyancy
It can float, produce scum silica frost, and then form fine and close crust.It causes the biogas produced in pond to gather and be obstructed, dischargeable capacity and gas storage
Between diminish, raw material availability reduction, the problems such as gas production is reduced occur.For example crust problem it is serious when, often make one it is complete
Good methane-generating pit becomes in " ill pond, useless pond ".Crust has turned into the protrusion hard nut to crack that current methane-generating pit is present.
Number of patent application 200520096563.1, a kind of device for removing methane-generating pit liquid level scum silica frost crust, prompting is
Using the storage pool and its flusher savings biogas pressure of a unidirectional inflow and outflow, after biogas pressure reduction, spray is utilized
Spill device and drench scum silica frost crust, drenched sinking is allowed to, to achieve the goal.
The method that online someone gives ingenious solution the scum in methane tank crust：When methane tank gas production amount is low in the winter time, first
The biogas in methane-generating pit is finished, all switches are opened, methane-generating pit is in zero-pressure state.Biogas connection is removed from airway tube
Sebific duct, allows daily produced biogas to airborne release, then to be added water naturally into methane-generating pit, is in methane-generating pit and completely fills state
5-7 days out of service.So the scum silica frost on methane-generating pit upper strata can be made to be immersed in biogas slurry, in the case of constant pressure, scum silica frost will be certainly
It is dynamic to drop down to form sediment, recycle automatic slag discharge device to draw out biogas residue to come.
Curve tunnel type methane-generating pit is also hydraulic type biomass pool, and only curve tunnel type pressure limiting valve used for methane tank is replaced
Water pressure chamber, monomer pond holds many in 1000m3More than, it is be used as in large-scale production biogas more, occur in marsh gas fermentation processes
A large amount of scum silica frost, grow situation caused by above-mentioned crust also occur if do not dealt with the time one.Because curve tunnel type methane-generating pit is
It is operated in continuous flow procedure, biogas pressure during pressure limiting valve pressure limiting between gas storage is substantially stabilization, the i.e. natural pond of sweathouse
Liquid horizontal plane is basicly stable, will not be significantly raised and lowered as existing hydraulic type biomass pool horizontal plane, it is clear that above-mentioned is skilful
The wonderful method and patented technology for solving the scum in methane tank crust is in spite of effectively can not being all applicable.
A kind of divisional application of methane-generating pit of the invention as the applying date 2017 year 06 month 07 is difficult to solve this technology
Topic.

The device of scum silica frost.
To realize goal of the invention, present invention employs following technical proposals.
The device of scum silica frost in a kind of removing methane-generating pit, including hydraulic type curve tunnel type methane-generating pit, a fixed U-tube
Between before and after envelope wall bottom is connected across between terminal gas storage through curve tunnel type methane-generating pit, U-tube enters before envelope wall between gas storage
Mouthful than in methane-generating pit pressure limiting valve pressure limiting in pond sweathouse the low 0.2~10cm of biogas slurry horizontal plane, U-tube after envelope wall between gas storage
One closed scum filtering device of outlet connection, closed scum filtering device is connected with water pumper suction hose water, and water pumper is produced when working
Pull of vacuum, makes in pond between biogas slurry horizontal plane and gas storage the U-tube entrance formation height of water before envelope wall, and the scum silica frost of suspension is preferential
Fall into the biogas slurry between gas storage before envelope wall after U-tube entrance, filtering scum silica frost to be extracted out by water pumper, stay in the scum silica frost of filter core then every mistake
Certain time opens closed scum filtering device removable cover and takes out filter core removing.
U-tube entrance is a word V-arrangement funnel inlet before envelope wall between gas storage.
The closed scum filtering device filter core that U-tube is exported after provided with envelope wall between removable cover outer casing container and parcel gas storage
Composition,
U-tube is to pour to be made on envelope wall between gas storage.
Water pumper delivery port is connected with methane-generating pit stirring pipe water, and biogas slurry press-in stirring pipe, stirring fermentation are extracted out by water pumper
Between.
As a result of abovementioned technology, the present invention can obtain following technique effects.
