Description
Technical field
The present invention relates to technical field of methane, more particularly to a kind of defoaming methane-generating pit.
Background technology
Biogas is made of multiple gases mixing, and wherein main component is methane.It has often been said that biogas fermentation refer to natural pond
Gas bacterial decomposition organic matter, produces the process of biogas.According to the effect of all kinds of bacteriums in marsh gas fermentation processes, biogas bacteria can be with
It is divided into two major classes.First kind bacterium is called decomposer, its effect be by complicated organic matter resolve into simple organic matter and
Carbon dioxide etc..There is special decomposition of cellulose among them, be cellulose-decomposing bacteria；There is special decomposing protein, be albumen
Decomposer；Have special lipolytic, cry lipolysis bacterium；Second class bacterium, which cries, contains methane bacteria, is usually methane backeria, it
Effect is that simple organic matter and carbon dioxide are aoxidized or are reduced into methane.Therefore, organic matter becomes the process of biogas, all right
Than producing a kind of two procedures of product in factory：It is that decomposing bacteria adds the organic matter of the complexity such as excrement, stalk, weeds first
Work is into semi-finished product, i.e., compound simple in structure；Besides under the action of methane bacteria, simple compound is processed into production
Product, that is, generate methane.With the development of China's biogas science and technology and the popularization of rural household biogas, according to local requirement
There is the hydraulic type pond of fixed ledge with condition, household methane tanks such as temperature, geology, take off lid hydraulic type pond, hanging tube type hydraulic type greatly
Water hydraulic type pond, separation cover-floating type pond, semi-plastic type pond, Full-plastic pond and pot type pond are returned in pond, meandering distribution hydraulic type pond, top.Shape
Formula is although varied, but sums up substantially by hydraulic type biomass pool, float cover type biogas generating pit, semi-plastic type methane-generating pit and pot type
Four kinds of fundamental types of methane-generating pit change what is formed.Wherein hydraulic type biomass pool has lot of advantages, is mainly manifested in following four
Aspect：First, pond body structure tension performance is good, and makes full use of the bearing capacity of soil, so labor and material saving, cost compares
It is low.2nd, suitable for loading a variety of fermentation raw materials, particularly substantial amounts of crop material, collect manure to rural area highly beneficial.3rd, for ease of
Often charging, lavatory, pigsty can be built in above methane-generating pit, and excrement can be swept into pond at any time.4th, around methane-generating pit all with soil
Earth contacts, and has certain effect to pond body insulation.Although hydraulic type biomass pool has the advantages of above, there is also many shortcomings：
First, since air pressure changes repeatedly, this has unfavorable shadow to pond body intensity and lamps and lanterns, the stabilization of kitchen range efficiency of combustion and raising
Ring.Second, due to no agitating device, scum silica frost easily crusts in pond, and is difficult to crush, so the utilization rate of fermentation raw material is not
Height, pond hold factor of created gase, i.e., the gas production of every cubic metre pool volume diel is relatively low.Third, since removable cover diameter cannot increase,
To fermentation raw material for the methane-generating pit based on stalk, the big Comparision that discharges is difficult.Publication No. CN 201296755, it is open
Day disclosed a kind of spherical Water pressure type glass fibre reinforced plastic methane, including episphere for the Chinese patent literature of on 08 26th, 2009
And lower semisphere, and it is furnished with feed pipe and gas-guide tube；The feed pipe tilts from episphere and is inserted between gas storage and stretches into lower semisphere
In sweathouse；Gas-guide tube is arranged on the top of episphere and is communicated between gas storage；Discharge port on the episphere side wall is equipped with one
The curved tailgate of a indent；Discharge port is directly communicated with the side wall of water pressure chamber, and the gravity support of water pressure chamber is in the outer wall of episphere
On.
Discharge outlet of the patent document on episphere side wall sets the curved tailgate of an indent, discharge port directly with
Water pressure chamber side wall communicates, when the methane quantity produced in sweathouse is larger, when biogas is full of between gas storage, liquid in sweathouse due to
The pressure of biogas and decline liquid level, when liquid drops to curved baffle bottom, biogas more than needed is just along curved baffle wall
Discharged from water pressure chamber, so as to avoid the excessive and quick-fried pond of air pressure.But the patent document is floated since structure design is unreasonable in pond
Slag easily crusts, and is difficult to crush, so the utilization rate of fermentation raw material is not high, factor of created gase is very low.
The content of the invention
The defects of in order to overcome the above-mentioned prior art, the present invention provide a kind of defoaming methane-generating pit, and the present invention is by setting too
Positive energy heat collector, can keep temperature good in fermenting cellar, and motor drives blade rotation to produce whirlpool, can make proferment
Material fully decomposes, and then improves biogas output.
