Description
Technical field
The invention belongs to methane-generating pit fields, and in particular to methane-generating pit is used in a kind of fermentation of environmental-protection organic matter matter.
Background technique
Biogas be organic substance in an anaerobic environment, under conditions of certain temperature, humidity, pH value, pass through micro- life
Object fermentation, a kind of fuel gas of generation.
With China's expanding economy, social progress, life of urban resident is further improved, but rural resident
There are still many problems for life.Since mankind's activity is frequent, the energy, a large amount of air storage stalks and feces of livestock and poultry are largely consumed
Deng, cause great amount of carbon dioxide discharge, aggravated greenhouse effects.
New countryside construction seems very necessary.This requires development rural ecological mode of agriculture, improve rural environment,
The ambitious goal increased farmers' income.Wherein comprehensive utilization methane-generating pit is exactly an important channel for changing rural environment, biogas
The use in pond can be reduced the generation of problem above to a certain extent.And build a methane-generating pit and can be used 20 years or so, it is comprehensive
Conjunction make good use of methane-generating pit not only can it is energy saving, improve and protection environment, there are also save chemical fertilizer and pesticide, improve crops
Many benefits such as yield and quality, promotion and the development of drive animal husbandry.
But when the usage amount of biogas in methane-generating pit is little, it is easy to cause biogas bulk deposition in methane-generating pit, Jin Erhui
Pressure in pond is greatly increased, security risk is easily caused.To solve the above-mentioned problems, common practice has two in the prior art
Kind, one is being vented directly in atmosphere, alleviate pressure in methane-generating pit, this method will lead to energy dissipation and environmental pollution,
When in biogas methane and air mix according to a certain percentage when, it is also possible to set off an explosion, cause security risk；Second is meeting
In addition one gas collector is set outside methane-generating pit spare, but for average family, biogas is excessive in usual pond
Situation is less, if a gas collector is separately provided, not only increases cost, and increase occupied area and safety are hidden
Suffer from.
Summary of the invention
The technical problems to be solved by the present invention are: biogas is in methane-generating pit when bulk deposition in the prior art, either
The problem of freely discharging or in addition collecting all existing defects is, and it is an object of the present invention to provide a kind of environment-friendly type to solve the above problems is organic
Fermentation of materials methane-generating pit.
The present invention is achieved through the following technical solutions:
A kind of environmental-protection organic matter matter fermentation methane-generating pit, including the methane-generating pit ontology with inlet port and outlet port, institute
It states in methane-generating pit ontology and pumping equipment is installed；
The pumping equipment includes the kickboard for being placed on biogas slurry surface in methane-generating pit ontology, multiple to be fixed below kickboard
Float, the venthole in kickboard between float run through methane-generating pit through kickboard and the drain inner tube that extend into biogas slurry
Ontology and be located at methane-generating pit ontology apical position at drain outer tube and one end connect with the top of drain inner tube, the other end
The connection hose being connected to drain outer tube；
The drain inner tube is fixed in kickboard, if the length for the drain inner tube extending into biogas slurry is L, then L is less than
20cm。
Kickboard in the present invention can follow the lifting of biogas slurry and go up and down, and be always positioned at the surface of biogas slurry in methane-generating pit ontology,
Thus biogas slurry only can be extruded into methane-generating pit ontology effectively when methane content increase leads to pressure increase in methane-generating pit ontology.
Thus, by the setting of above structure, in the excessive situation of biogas, do not have to discharge biogas, by the pressure of biogas by biogas slurry
It is pressed into drain inner tube, the biogas slurry that will be pressed into drain inner tube by connecting hose is discharged to drain outer tube, and then outside drain
Methane-generating pit ontology is discharged in pipe, alleviates the intrinsic pressure of methane-generating pit, solves security risk caused by biogas accumulation excessively.
Mode of the invention makes drain inner tube bottom end be always maintained at place by the synergy between drain inner tube and kickboard
In the supernatant liquor of biogas slurry, thus the supernatant liquor being only discharged in biogas slurry, it is reduced by the way that supernatant liquor is discharged in time
The intrinsic pressure of methane-generating pit, and then guarantee the safety of methane-generating pit.Thus the present invention is in the case where guaranteeing methane-generating pit safety, no
It is only capable of effectively biogas being avoided to be discharged in air, reduces and even avoid pollution, effectively save energy wave caused by biogas empties
Take and biogas evacuation procedure present in security risk；Moreover, setting through the invention separately increases without outside methane-generating pit
If a biogas collection device, reduces and increase biogas collection device and increased occupied area, while reducing increase gas collection
The cost input of device, effect are more significant.
Moreover, the setting of structure through the invention, moreover it is possible to which the dross being effectively isolated in biogas slurry avoids the discharge of dross, should
Setting is not only only capable of that dross fermentation is maximumlly utilized to generate biogas, the effective rate of utilization of organic matter is improved, it can also effectively
Environmental pollution caused by the discharge of dross is avoided, effect is very significant.
Further, the float is in up big and down small conical structure.The kickboard is made of hard plastic board, described floating
Son is made of foamed plastics, and kickboard swims in biogas slurry surface by the effect of float.
By the optimal setting of above structure and material, the surface that kickboard swims in biogas slurry always, and side can be effectively ensured
Just the biogas generated in biogas slurry is stacked into the top of methane-generating pit ontology, does not influence the generation of biogas.
Residue is taken out of when entering in drain inner tube in order to avoid biogas slurry, avoids the blocking of drain inner tube, while effectively convenient
Residue is discharged from discharge port, and methane-generating pit ontology bottom end is arranged in inclined-plane, and drain inner tube is located at the top of surface bottom.
It is that drain inner tube is always positioned at inclined-plane in order to avoid the movement or rotation of kickboard drive the shift in position of drain inner tube
The top of bottom end is also equipped with U-shaped locating part on the inner sidewall of the methane-generating pit ontology, is additionally provided in the kickboard and protrudes into U
Limit latch in the U-type groove of type locating part.
Preferably, the U-shaped locating part is two, is separately positioned on the opposite sides of methane-generating pit ontology.
Further, the connection hose is flange-connection stainless steel metal flexible pipe, the length of the connection hose and the height of U-shaped locating part
It spends identical.The length of the L is 5~10cm, and the height of the float is less than L at least 1cm.
Compared with prior art, the present invention having the following advantages and benefits:
1, mode of the invention effectively can avoid biogas from being discharged in air, reduce and even avoid pollution, effectively saving natural pond
Energy waste and security risk caused by gas emptying；And the present invention is not necessarily to increase occupied area, and reduces cost input,
Security performance is improved, effect is more significant；
2, the dross in biogas slurry is isolated by kickboard in the present invention, prevents dross to be discharged by drain pipe, avoids the row of dross
Environment is polluted out, while preferably generating biogas using dross fermentation, improves the utilization rate of organic matter.
