Description

Biogas production, deposit, use three utensils merge the use combined facility

One, technical field

The present invention relates to the facility of a kind of biogas production, deposit, use, particularly residents biogas production, deposit, the independent structure of use three technology, isolated operation, become three different utensils, the combined facility of merge using then.

Two, background technology:

Biogas technology has three bulks, and the one, production, the 2nd, deposit, three is to use; The biogas technology that methane-generating pit adopted of present most of residents, be to collect production, lay in, use this three bulks technical project on the structure of a methane-generating pit, such design does not break through for a long time and changes, this is incomplete, but should cut apart this three bulks technology and independent utilization, its superiority division is as follows:

Biogas production (container): biogas production technology independently is an extremely simple production technique, and under correlated condition, only needing an airtight container can set up.Container only needs to be filled with water, and is simple in structure, can select material cheaply, and materials reduce, and difficulty of construction reduces.

Biogas deposit (container): biogas redundancy technique independently, be one and extremely simply lay in technology, only need an airway, be connected in and produce in the airtight container of biogas, just the deposit that can concentrate biogas is in a container, and the biogas that container only needs can packing quality to be lighter than air can be set up.Simple in structure, and the materials of container can select material cheaply, and can endlessly lay in.

Biogas uses (container): biogas use technology independently, be one and extremely simply use technology, have two kinds of technologies the most preferred: " the one, only need in the biogas tank of a lower cost materials; produce the pressure of setting; be the kitchen range combustion efficacies; the simplest and be exactly that water hydraulic gas forms pressure assembly simple in structure cheaply, just can stablize and the isostatic air feed burns; The 2nd, only need in not having the airbag of pressing deposit biogas, gas to be extracted out direct air feed and burn to kitchen range with a miniature vacuum fan." these two kinds of technologies use mutually, learn from other's strong points to offset one's weaknesses, water hydraulic gas does not need electric power, but air feed uses in a large number; Miniature vacuum fan air feed in a large number uses, but can not use when having a power failure.

The application of the biogas technology of existing residents, often collecting biogas production, deposit, use designs on the structure of a methane-generating pit, promptly do not have the fully independently technological process of three kinds of different operating principles, can not divide concrete production, deposit, use these three kinds different biogas apparatuses.As hydraulic type biogas production, deposit, use design in the same container that the feed liquid fermentation is housed, hydraulic type, cover-floating type are the biogas deposit and use antagonism by feed liquid and the gas pressure that recoils to form, cover-floating type designs biogas deposit and use in same utensil, and is improved and next various methane-generating pits by these two kinds of pond types.Such design does not have three kinds of different principle of work, cuts apart to make its single separate structure, isolated operation, but combine, it has just produced many defectives so, and is not easy to the problem using and manage, its problem exist division as follows:

Biogas production: in the same container of producing biogas, storage must be robbed with feed liquid and be taken up space in the biogas, and useful volume is reduced, and causes and builds the pool volume increase; Biogas and the feed liquid recoil pressure that in same container, creates antagonism, pressure changes repeatedly between the 40-160cm water colunm pressure, the pond body bears highly compressed for a long time and impacts, cause biogas to leak in a large number easily, in the situation of reality, most of methane-generating pits all can not guarantee to use normally gas, particularly under the situation in winter, mostly need replenish daily use with other energy and material; The pond body is fragile, and work-ing life is not long, and in the situation of reality, most of methane-generating pits can only use 3-5 just no longer handy, or completely written-off can not having re-used; Avoid the generation of this phenomenon, necessarily require the expensive pond material of building, increased the difficulty of construction, increased and built the pond materials, in the situation of reality, cause residents to build the pond cost generally up to 1000 yuan, or the amplitude more than 1000 yuan; Owing to dried, wet two spaces are arranged partly, dried, wet spatial pressure change factor is arranged again in the pond, scum silica frost easily crusts, in case crust can thicken in increase progressively, takes up space, and raw material availability is low, and factor of created gase is low, is difficult to fragmentation again, causes the difficulty of using with management.

Biogas deposit: in fermentation vat, lay in biogas, the biogas deposit is restricted, can not endlessly lay in, in the situation of reality, summer the gas production rate height, and gas consumption is few, the gas that fecund goes out often needs venting avoiding damaging methane-generating pit, or under the effect by the antagonism recoil pressure of biogas and feed liquid, feed liquid is discharged to automatic exhaust after the gauging line of charging end opening, make a large amount of having slatterned of biogas, and the gaseous tension extra-high-speed in the air guide pipeline causes pipeline easily, joint, valve damages or gas leakage, and both having made is follow-on cover-floating type methane-generating pit, its shortcoming is same, can only in the quite little floating cover of volume, lay in, can not lay in biogas in a large number, in fact, biogas is a kind of gas that is lighter than air, volume or this expensive material of floating cover with fermentation vat are laid in biogas, cause the materials cost height of biogas deposit, and complex structure, be difficult to safeguard and maintenance meaningless increase cost again.

Biogas uses: by the antagonism recoil pressure of biogas in same container and feed liquid, produce supply gas pressure, but the antagonism of biogas and feed liquid recoil pressure change impermanence, it is low when time thes be high, therefore pressure transient all has adverse influence to the stable of light fixture, kitchen range efficiency of combustion with equilibrium with balanced; Again because methane-generating pit is easy to generate scum silica frost crust, in case crust promptly begins to occupy gas storage space, coexist in the space with biogas, the increase gas storage pressure that a spot of gas storage is just unusual slightly once not had with gas, can't normally use the user or grasps and use gas.

Except that this three bulk, improving the useful volume utilization ratio in addition, the organism utilization ratio, the deslagging technique of organic matter fermentation speed and effective descum and sediment, these several technology but have deficiency on the existing methane pool structure design, cause this cheapness of biogas and fine renewable energy resources product, can not obtain abundant development and utilization, cause the source of manure of organic biofertilizer to cause waste greatly, vast farmers also needs to buy to market with organic bio-fertilizer, cause the production and the development of Chinese Organic farming to be restricted, the meaningless again input cost that has increased Organic farming production.

Three, summary of the invention:

Biogas production, deposit, the use three technology that the invention discloses a kind of residents is the biogas combined facility that separate structure, isolated operation, merging are respectively used; Separate structure is meant production, deposit, uses three kinds of different biogas principle of work respectively, and dividing to come respectively becomes independently biogas utensil; Isolated operation is meant three kinds of different biogas utensils, independently finishes the biogas technical process of self; Merge to use to be meant that multinomial technology such as three kinds of different biogas utensils and deslagging can combine with utensil and to be connected use, the one that becomes merging is used in combination facility.Zu He residents biogas facility like this, can be according to different biogas principle of work, select different cheaply utensil building that is suitable for or the utensil structure material of making, and processing requirement by different utensils, design the manufacturing of different utensils or the construction standard of building, therefore can reduce input cost greatly, reduce the difficulty of manufacturing process and building operation; And different biogas utensils divide body structure, respectively execute its can, each one does his duty, isolated operation, the result of use and the practicality of biogas technology have been improved, simplified difficulty and the complicacy of use, solved to collect biogas production in the past, lay in, be used in the many defectives that caused on the structure of a methane-generating pit and be not easy to peasant household and used and the problem of managing with management.

Biogas production of the present invention, deposit, use three utensils merge the use combined facility, comprise " no air pressure marsh gas fermentation pool ", " no pressure biogas deposit device ", " air storage chamber ", " hydraulic pressure pond ", " miniature vacuum fan ", " scum pipe " multiple altogether different utensil compositions, different is the production that " no air pressure marsh gas fermentation pool " is exclusively used in biogas, " no pressure biogas deposit device " is exclusively used in the deposit of biogas, " air storage chamber ", " hydraulic pressure pond " reach the use that " miniature vacuum fan " is exclusively used in biogas, and flexible " scum pipe " automatically is exclusively used in deslagging.

" no air pressure marsh gas fermentation pool " is airtight container, and design has between fermentation vat, feed-pipe, discrepancy, flexible automatic row's sediment pipe, water vent, gas port, Gong Gai, water reservoir, detritus pool; Fermenting container is shaped as cylindrical, and the pond body is a brick mix structure, and methane-generating pit pond body is the thick shell of 4-6cm; Fermentation vat is imbedded underground, is used to adorn organism, water, biogas bacterium etc. and secluding air, and organism is fermented in the pond; Feed-pipe is located at by the body of pond, is used to into organic matter raw material and water; Be located between discrepancy by the body of pond, and be higher than the through ground of pond body, be used to pass in and out the passage in the pond, be convenient to maintenance and maintenance, and clear up, be used to set simultaneously the feed liquid elevation of water surface again; Flexible automatic row's sediment pipe is located between discrepancy other, bottom tube mouth straight cutting is gone into the fermentation vat bottom position, upper orifice is a little more than the elevation of water surface of setting between coming in and going out, then be hung on the outside between discrepancy at ordinary times, treat that the time spent takes off the pipe section that top can be crooked, be bent downwardly the back and form the height of water pressure that descends suddenly, discharge at the next automatic sediment of pressure with the fermentation vat bottommost; Water vent is located at top between discrepancy, is used for discharging automatically the water liquid that has more in the fermentation vat, is used to set simultaneously the elevation of water surface of fermentation vat again, remains the useful volume of full dress fermentation; Gas port is located on the vertical guide pipeline of fermentation vat arch lid, and production well and a little more than the water vent height that sets is used for automatically the biogas of institute's output in the outside discharging pond.

" no pressure biogas deposit device " is airtight container, and design has airbag, adjustable pressure limiting valve, gas port, two admittance tracheaes; Airbag is plastic cloth or plastic-coated fabric manufacturing, hangs on the buildingss such as house, is used to lay in biogas; Adjustable pressure limiting valve is the observable transparent tube of a U-shaped, dress water liquid in the pipe, with the height of water as water column cm pressure, be used for setting and regulating " air storage chamber " and the biogas deposit in " hydraulic pressure pond " and the pressure criteria of use, two mouth of pipe upper ends at U-shaped, and be higher than the interior water liquid place of pipe a pipeline that can lead directly to is arranged, a valve is arranged in the pipeline, valve is closed when the pressure delivering gas, when not having the delivering gas of pressure, open the valve passage of straight-through pipeline, by directly not having the pressure gas transmission through airway in the fermentation vat; Gas port is located on airbag, is used for the air inlet deposit or uses for exhaust; Two admittance tracheaes, the external threeway of gas port, other other two logical respectively connects an airway, is used to connect other utensil.

" hydraulic pressure pond " respectively is a container with " air storage chamber ", it is underground that air storage chamber is that brick mix structure is embedded in, the former water liquid that is equipped with of air storage chamber, at the top of air storage chamber one little space is arranged, communicate with the gas port of fermentation vat, be used to lay in biogas, gas-storing capacity is set in maximum using gas quantitative standards amplitude, the residents methane-generating pit divides deposit biogas three times by three meals in a day, and quantitative criterion can reach result of use under normal conditions; It is underground that the hydraulic pressure pond is that brick mix structure is embedded in, there is a small tubes passage to communicate with the bottommost of air storage chamber, hydraulic pressure pond and be higher than air storage chamber, it is that bottom, hydraulic pressure pond differs 15-20cm with the air storage chamber top that the residents methane-generating pit is higher than amplitude, be used for air storage chamber water liquid is all drained into the hydraulic pressure pond, and produce the water column cm pressure that sets when using biogas; The gas port of gas port and fermentation vat is a same guide pipeline, and promptly fermentation vat enters the air inlet port of air storage chamber and the gas port of air storage chamber is same gas port.

" miniature vacuum fan " is a small-sized alternating-current vacuum fan, can select impeller pump vacuum fan or oxygenating machine for use, family's residents supply gas pressure is designed to the water colunm pressure greater than 16cm, other uses the pressure design of the combustion efficacy of biogas by demand, can be in choosing on the market, be connected to one of them the parted hair airway on " no pressure biogas deposit device " two admittance feed channel, to the burner air feed.

The method of attachment of several different utensils: " no air pressure marsh gas fermentation pool " outwards has two gas ports, a gas port is connected to " air storage chamber ", another gas port connects four-way after connecing airway again, other three is common to and connects other utensil, the two admittance tracheaes of " no pressure biogas deposit device ", after one of them airway connects " adjustable pressure limiting valve ", be connected to wherein logical in the four-way again, after another airway connects " miniature vacuum fan ", be connected to wherein logical in the four-way again, last in the four-way leads to and connects burner.

The technical solution used in the present invention is characterized as: " no air pressure marsh gas fermentation pool " is full dress fermentation, behind the output biogas, enter " air storage chamber " by the gas port guiding gas, before entering, hindered by original water liquid in the air storage chamber, because resistance makes gas can't enter air storage chamber for the moment, biogas is forced to the back back-pressure and returns, the antagonism of feed liquid recoil pressure in generation and the pond, antagonism recoil pressure compression is in the decline of the feed liquid in the tiny guide pipeline under the gas port, the feed liquid that descends is discharged from " no air pressure marsh gas fermentation pool " water vent of setting height, the methane gas producing amount progressively increases, antagonism recoil pressure is progressively increased, just cause also being in that the feed liquid in the tiny guide pipeline progressively descends under the gas port, the degree of depth that descends causes water column cm poor with the setting height of " no air pressure marsh gas fermentation pool ", this water column cm difference is biogas and the formed water column cm of feed liquid antagonism recoil pressure pressure, when the formed water column cm of antagonism recoil pressure pressure is consistent with the water liquid resistance in the air storage chamber, water liquid resistance in the air storage chamber just can begin to get excited, the water liquid that impulsion power can be got excited in the air storage chamber enters into the hydraulic pressure pond, the hydraulic pressure pond is higher than air storage chamber, two Room total heights be " hydraulic pressure biogas use the pond " water column cm limit of pressure, have only when the formed water column cm of antagonism recoil pressure pressure and " hydraulic pressure pond ", when the two Room total height water columns of " air storage chamber " are consistent, could all be discharged to the water in the air storage chamber in the hydraulic pressure pond, at this moment the biogas of being laid in the air storage chamber, its pressure is the water column cm limit of pressure of two Room total heights, gas in " air storage chamber " enters burner behind gas port and airway, open valve pressure and can form the burning result of use, when not using biogas, to constantly there be biogas to enter air storage chamber, cause air storage chamber pressure after limit of pressure, to begin again to increase, therefore the gas in " air storage chamber " through gas port and airway after adjustable pressure limiting valve enter automatically in " no pressure biogas deposit device ", the pressure that adjustable pressure limiting valve is set is consistent with the limit of pressure of air storage chamber, the gas that has more the so adjustable pressure limiting valve of under pressure impulsion, can getting excited, automatically enter endlessly then in " no pressure biogas deposit device ", endless deposit, and on another airway of " no pressure biogas deposit device ", be connected to " miniature vacuum fan ", when needing usefulness gas vacuum fan is connected with the mains, open the valve of the preceding airway of vacuum fan, just can extract a great reserve of biogas in " no pressure biogas deposit device " out, the air feed burning is used.

The obtained technical progress of the present invention is: the biogas production of residents, deposit, use three kinds of different biogas principle of work to go to finish by three kinds of different structure utensils, variant utensil isolated operation does not mix mutually, technology applied defect and management use problem when mixed in together have been eliminated, " no air pressure marsh gas fermentation pool " is exclusively used in the task of finishing biogas production, the fermentation vat volume of can completely having adorned fermentation 100% utilization, improved useful volume, raw material availability 100%, improved factor of created gase, and the impact that is not stressed of the pressure that does not have deposit biogas in the pond, pond body not only can increase the service life, the residents methane-generating pit can ensure user's lifelong use, all right shell structure reduces materials, can reduce the quality standard of select materials again, and reduction difficulty of construction, because isolated operation has improved result of use and practicality, not only user-friendly and management, and function increases, the organism sediment can be got rid of automatically, big cleaning can be do not needed; " no pressure biogas deposit device " is exclusively used in the task of finishing the biogas deposit, and 1 cube of m only is several yuans, can increase margin with a plurality of airbags, can significantly reduce the gas storage cost, can make gas storage unrestricted again, but commercialization production; " air storage chamber ", " hydraulic pressure pond " and " miniature vacuum fan " are exclusively used in the use of biogas, two kinds that provide to the user are used in combination mode, can adopt as much as possible again simultaneously not have and press the mode of carrying biogas, increase the service life as much as possible and avoid the biogas of air guide pipeline and utensil to leak.

Four, description of drawings:

Figure one is the present invention's's " no air pressure marsh gas fermentation pool " vertical view, and figure two is the one-piece construction synoptic diagram of all facilities of the present invention.

Five, embodiment:

In the specific embodiment of the present invention, feed-pipe 5 connects the blowdown ditch, methane-generating pit and pigsty, connections such as lavatory, water and organism enter into fermentation vat 1 through feed-pipe 5, output biogas is decomposed in fermentation in airtight container 1, fermentation vat 1 is full charging fermentation, scum silica frost covers 2 times at arch and is pressed in the water, decomposing and fermenting fully, do not produce scum silica frost crust phenomenon, the biogas of the output productive set that floats naturally covers under 2 the top in arch, it is the end opening of gas exhaust duct 3, biogas overflows outside the pond through gas exhaust duct 3 natures, at

valve

19,21,22 and the obstruction of adjustable pressure limiting valve 17 under, biogas enters in airtight air storage chamber 11 through another escape orifice 15 on gas exhaust duct 3 tops, the water liquid that flows into from hydraulic pressure pond 10 is arranged in the airtight air storage chamber 11, are being banketed in 4 top in air storage chamber 11 and hydraulic pressure pond 10, continuous output gas in the fermentation vat 1, gas constantly enters in the air storage chamber 11, cause the gas storage pressure in the air storage chamber 11 to rise, water liquid in the air storage chamber 11 can be expelled back in the hydraulic pressure pond 10 through pipeline 14 by the gas storage pressure that rises, gas storage pressure in the air storage chamber 11 rises to and air storage chamber, when the two Room total heights in hydraulic pressure pond are consistent, at this moment pressure promptly is the pressure of the water column centimetre of two Room total heights, water liquid in the air storage chamber 11 all can be drained in the hydraulic pressure pond 10, the pressure of setting adjustable pressure limiting valve 17 is consistent with the water column cm pressure of two Room total heights, perhaps slightly high, when at this moment the pressure of the gas storage pressure in air storage chamber 11 and the adjustable pressure limiting valve that sets maintains an equal level, both counteracted by pressure, biogas is through airway 16 adjustable pressure limiting valve 17 of can getting excited, enter into no pressure biogas deposit device 18 endless deposits automatically, what the present invention was designed outwards carries the mode of biogas to have two kinds by methane-generating pit, a kind of is that pressure is carried biogas, mode of movement is the biogas of output in the fermentation vat 1, constantly enter in the air storage chamber 11, in running into air storage chamber 11 under the water blocking of original water liquid, force the gas back-pressure and return in the gas exhaust duct 3, form the water liquid in the gas back-pressure gas exhaust duct 3, water liquid is pressed progressively to descend, water liquid is discharged minor amount of water liquid in the gas exhaust duct 3 by water port 24, discharge great water liquid and just form great water column cm pressure, can progressively the water liquid in the air storage chamber 11 be drained in the hydraulic pressure pond 10 by the pressure that progressively forms, at last water liquid all is drained in the hydraulic pressure pond 10, at this moment discharge head reaches the water column cm pressure of two Room total heights, the pressure of gas back-pressure gas exhaust duct 3 also can just be emptied to original water liquid in the gas exhaust duct 3 end opening of gas exhaust duct 3, the water liquid height 26 that sets in the former gas exhaust duct 3 is consistent with the height of methane-generating pit drainage pipeline 24, behind the water liquid in the emptied of exhaust gases pipeline 3, water level decline by the gas exhaust duct 3 after methane-generating pit drainage pipeline 24 and feed-pipe 5 elevation of water surface and the emptying forms the height of water, produce the water column cm pressure in gas exhaust duct 3, but owing in the fermentation vat gas storage is not arranged, so fermentation vat still is no atmospheric pressure state, produce pressure then and carry biogas, be the pressure that is always keeping consistent in the air storage chamber 11 with adjustable pressure limiting valve 17, and transfer out biogas through adjustable pressure limiting valve 17, its shortcoming is to carry because of pressure, require air storage chamber air tight condition height, but because gas storage pressure is lower, general only between the 40cm water colunm pressure, also ensure air tight condition easily; Another kind is that no pressure is carried biogas, method is after holding hydraulic pressure pond water liquid completely, open the cover plate of small sircle hole 12 above the hydraulic pressure pond 10, stretching hand goes in the hydraulic pressure pond 10 with obstruction 13 obstructions suitable for reading with 14 pipelines, water liquid can't pass back in the air storage chamber 11 more like this, the pressure of water liquid in air storage chamber 11 disappears automatically so, make air storage chamber become passive state, after no pressure, the gas adjustable pressure limiting valve 17 of can't getting excited, at this moment can open valve 21, the provisional use that eliminates adjustable pressure limiting valve, airway 16 becomes does not so have the gas pipe line of pressure, and biogas flows naturally and flows in the no air pressure biogas deposit device 18, but do not press the life-time service of carrying support facility because of having, and 100% avoids leaking biogas; The designed biogas use-pattern of the present invention has two kinds, and a kind of is that hydraulic pressure biogas uses, by the gas that contracts of the water hydraulic in the hydraulic pressure pond 10, treat the full gas of air storage chamber storage after, during use, open the valve 19 before the kitchen range 20, air feed uses for kitchen range 20 igniting; Another kind is the gas use that miniature water pump 23 is extracted out not to be had in the pressure biogas deposit device 18, method is to open the startup work of connecting with the mains of

valve

22 and 19 vacuum fan 23, air feed uses for kitchen range 20 igniting then, for the residents methane-generating pit is that two kinds of methods that biogas two kinds of methods of carrying and biogas use are used in combination, under the situation that electricity is arranged at ordinary times, adopt the method for no pressure delivering gas and miniature vacuum fan using gas, the monthly consumption of miniature vacuum fan is only about 2 degree, and under the situation that has a power failure, adopt the method for pressure delivering gas and hydraulic pressure using gas; Draining of the present invention and deslagging mode be, the methane-generating pit draining mouth of pipe 24 of setting, and the natural pond liquid that has more in fermentation vat 1 can flow in the water reservoir 7 naturally through the draining mouth of pipe 24; On the wall in 6 outsides between discrepancy, design has a special-purpose scum pipe 8, scum pipe 8 tops be can be crooked pipeline, crooked amplitude arrives at 25 of scum pipe 8 and highly locates, flexible department is hung on top, 6 outside between discrepancy at ordinary times, the crooked pipeline bottom is connected to plastics tubing, and be fixed in 6 outsides between discrepancy, the end opening 27 of scum pipe 8 passes between discrepancy 6 and enters into the fermentation vat inner bottom part, when the needs deslagging, the curved tube that is hung on 6 outsides between discrepancy can be taken off, bend towards in the detritus pool 9 that (water reservoir 7 is two ponds of up-down structure with

detritus pool

9,7 ponds are last, 9 ponds are following, 25 knees with scum pipe 8 suitable for reading, 9 ponds are high together, also cover 2 bottom tops at fermentation vat arch, water level is unlikely to drop to the end opening of feed-pipe 5 when deslagging, can avoid advancing air from the outside goes into the

fermentation vat

1, and 9 ponds grow than 7 ponds, grow part and be the dew mouth of detritus pool, be beneficial to scum pipe 8 to 9 pond bendings, make organic fertilizer and use with being convenient to from 9 ponds, slag tap), at this moment by after the bending original elevation of water surface is reduced to scum pipe 25 places suddenly, with feed-pipe, water level between discrepancy forms the height of water, under the height of water, form downward hydraulic action, sediment in the fermentation vat 1 can be entered in detritus pool 9 through scum pipe 8, if but when entering, have sediment in fermentation vat 1, to stop up the end opening 27 of scum pipe 8, even the height of water is arranged, but water liquid flows without the end opening 27 of scum pipe 8, cause water liquid can't flow in the scum pipe 8, at this moment can open 6 vertical cover plates between discrepancy, with a waddy sediment of end opening 27 is arranged, make its water liquid arrive end opening 27 places, make the water liquid scum pipe 8 of under pressure, flowing through automatically, at this moment just produce the hydrodynamic(al) effect, can be between coming in and going out the top with general agricultural tools, sediment is dug, by water liquid is mobile sediment is discharged in the detritus pool 9 together, after having arranged slag, again the curved part of scum pipe 8 is hung back original position, to keep the useful volume in original fermentation vat 1.
