Abstract
A method for generating marsh gas by sewage features that the level of organic sewage can be reversely raised to digest, discharge sewage and recover marsh gas. A stage-1 and a stage-2 pits are built to control the gas output of gas tube. The gas in stage-1 pit raises the level of liquid in stage-2 pit. The water pressure of stage-(pit is basically used to supply water to stage-2 pit whose water inlet is higher than level of liquid, benefiting level change in stage-1 pit and changing height of water inlet with stage-1 pit.
Description
The invention belongs to the defeated pressure device of biogas energy environmental protection facility and gas-liquid.
At present, existing patent application " fully automatic hydrodynamic operator by anaerobic energy " methane-generating pit, the international show of inventions gold medal in Beijing, it is the full-automatic facility of the self-supporting energy of anaerobically fermenting, number of patent application 901095621 and (hereinafter to be referred as " researchs ") such as " researchs of methane-generating pit fermented liquid automatic circulating system ", automatically natural pond liquid raise-position recycle is held environmental recvery facilities such as coprodaecum in automatic flushing lavatory, though their level of preceding paragraph makes biogas technology that very high level of automation be arranged, if the fermentation vat jar will stop production will be to the repacking of old pond the time.Its liquid raise-position flushing automatization charging discharging stirring etc. does not conform to and is suitable for family expenses pond (medium-sized or above optimum), and consequent " research " does not fit into conventional household methane tank yet.In order to open up a kind of more easy to be large, medium and small type natural pond liquid raise-position system based on small-sized pond, if to the above-mentioned rational faculty of doing " research ", proposing relative scheme is improved, be added on artificial or control automatically to gas flow size and switching, to not specific pond type, especially in conventional family expenses hydraulic biomass pool power base application, also just can be extensively and the situation that can not stop production in old pond under add the simple and easy configuration of facility.
" the two ponds of high-low pressure " content described in " research " is: " build two methane-generating pits, a pond is the standard normal hydraulic type biomass pool for the low pressure pond, and another pond is a high voltage pool.The shared ager in two ponds is flat at the bottom of zero-pressure liquid level and the ager.Low pressure pond input and output material is the same with common hydraulic type biomass pool, can be used as the one grade fermemtation pond of solid-liquid mixed fermentation.High voltage pool can make the biological filter, does the second order fermentation pond.A high-order pipe is established in the high voltage pool water outlet, and pipe is high need press high height and methane-generating pit intensity and decide by fermented liquid.Water inlet pipe is " U " shape pipe or " big pipe box tubule ", and pipe height ratio zero-pressure liquid level is to the high 100-200mm of elevation (size by ager bottom surface and high voltage pool zero-pressure liquid level area is decided) on high-order pipe top." U " shape pipe is introduced identical with the front.Water outlet is also introduced identical with the front with return water mode and principle.Two pond airways lead to apparatus by behind the coupling device with a pipeline.Coupling device can be made a water bottle, and the water of bottle end dress certain altitude inserts two airways by bottle stopper, and one connects the low pressure pond, and one connects high voltage pool.Air guide pipe range in low pressure pond is the high voltage pool water column height of high pressure limiting.The airway that connects apparatus is drawn with Y-tube from high voltage pool.The gas of high voltage pool elder generation usefulness during with gas, stand-by gas are when being lower than low pressure pond air pressure, and the gas in low pressure pond is exported by coupling device.The gas of high voltage pool can not lead to the low pressure pond owing to be subjected to water seal." (above-mentioned low pressure pond is to call low-level culture pool in the following text; High voltage pool, title secondary pond).
Can draw from literary composition: " the two ponds of high-low pressure " of this structure need establish the methane-generating pit of two approximate size, (there is certain lifting rate the side) is that the source of the gas that is " high voltage pool " (secondary pond) almost needs to advance natural pond liquid (sewage) raise-position by (" high voltage pool ") self-produced self-sufficiency because the secondary pond can not substitute this with little volume, because secondary pond normal gas producing amount is few, so just, the propelling quantity of unfavorable sewage, thus the practical value amount influenced.Especially the volume of building the secondary pond in public lavatory or family expenses pond, rural area in normally is low-level culture pool 1/3 or 1/4, because of after normally being digested and when the sewage of low-level culture pool water pressure house (6) stop certain hour enters secondary pond (being high voltage pool) by low-level culture pool, its gas deliverability is less, if strengthen the secondary pool volume, will make the cost of the original cost high voltage pool higher more than conventional pond.So it is little that the secondary pool volume can only be built, therefore make progress expel liquid also just still less, so under normal circumstances, low-level culture pool water pressure house (6) liquid is few because of secondary pond usefulness gas output gas, so it is also little that liquid is introduced the flow quantity in secondary pond, water pressure house () liquid mainly refluxes, and is to enter low-level culture pool.As lavatory volume 8m
3Low-level culture pool set up secondary pond fermentation vat again, secondary pond 2m
3Hold the 0.05m that is everlasting according to every cubic metre of pond of intrinsic experience public lavatory institute actual motion secondary pond factor of created gase
3About, main pond is 0,15m
3, i.e. 2m
3The secondary pond day and night the up reversal water yield at 0.1m
3About, especially the secondary pond repeatedly use gas, its hydraulic fluid total amount is about 0.05, natural pond liquid will satisfy twenty or thirty people's lavatory discharging coprodaecum or the flushing dose of the swinery more than five is insufficient, if strengthen secondary pond volume again, can be not more satisfactory from output and income.Especially to fermentation vat or three grades of ponds (two ponds that the secondary pond is above) of low concentration operation, the digestive organ of above relay anaerobic digestion flow process, liquid measure advances will be still less.
And " the high low level two ponds " content described in " research " is: " two pond zero-pressure liquid levels are one high and one low, and the discrepancy in elevation is fermented liquid force feed height and deciding optionally.The shared ager in two ponds, ager and high-order pond zero-pressure liquid level absolute altitude are together.Low level pond rising pipe exceeds at the bottom of the ager, and is flat with the highest liquid storage of ager position.The charging mouth of pipe and ager top are flat.At the bottom of the high-order pond water outlet bobbin carriage, length equates with low pressure pond rising pipe.Water inlet pipe is " U " shape pipe, is provided with identical with " U " shape pipe of introducing previously.Also available " big pipe box tubule ".When stopping to use gas, the fermented liquid in low level pond is pressed onto ager, and material mouthful when the fermented liquid in high-order pond flows to the low level pond by high-order rising pipe (or lavatory squat position or raw materials pretreatment pond) enters the low level pond.During with gas in the high-order pond liquid level be lower than the ager liquid level, the fermented liquid of ager just is back to high-order pond by " U " shape pipe, thus the realization automated cycle sees Fig. 5 for details." (above-mentioned low level pond is a low-level culture pool, high-order secondary pond).
It this sure be " high low level pond " than the benefit in " the two ponds of high-low pressure " be that low-level culture pool can be to secondary pond air feed, so even secondary pond gas production rate is few, still having the low-level culture pool aerodynamic force to advance replenishes, so do not influence effectively liquid input of secondary pond, but its structure disadvantageously: low-level culture pool feed and exhaust tube (9) footpath can only be little, can not be greatly (in order to avoid by in a large amount of again back pressure low-level culture pools of the high liquid of voltage rise and lose unidirectional hydraulic fluid raise-position effect), thereby brought the input and output material difficulty, be unfavorable for normal operation, so still be not suitable for the propulsive practical application of high organism pond liquid, it requires relatively need carry out branch filter etc. to the pre-treatment of general material, so extensively unsuitable.
According to the problems referred to above the present invention a kind of new gas control method is proposed, can relatively obviously improve after the improvement and just use effect, biogas presses natural pond liquid not have the automatic unidirectional raise-position of the power consumption of adding, and reaches the energy general assemble in the coventional type hydraulic type biomass pool, and air pressure lifting liquid measure is many.Do not influence the turnover easily of high organic assorted material again, reduced cost, can reduce secondary (7) volume several times, brought installation, production all to be easy to carry out.
The above core of Gai Shu method, it is the control circulation of adopting with gas (amount), can make low-level culture pool (6) combine unidirectional automatically upwards relay marsh liquid raise-position step by step with secondary pond (7), and its feed inlet and outlet can be big, also can be little, it is also few so promptly to have solved " high voltage pool " aerogenesis hydraulic fluid, and the problem of low level pond low-level culture pool (6) input and output material, also is suitable for being applied to the equipped propelling natural pond liquid in new, the old type of hydraulic type pond.
Lead to secondary pond (7) to holding as Fig. 1 low-level culture pool airway by switch (1) pilot-gas with gas tool switch (3), switch (2) also can be established in the secondary pond, switch (3) can be used as defeated with air cock (3), it also can be a pressure limiting displacement switch, switch (1) (3) can when promptly opening (1), promptly can close (3) near interlock control, open (3) and promptly can close (1), also can separate near each self-acting control; If with a trident on-off control, switch (1) (2) (3) can be only with switch (1) the threeway control of one three port, and the rotation of switch (1) is respectively: low-level culture pool (6) (without gas the time) conductive gas is led to secondary; The general gas place (when using gas) of holding, secondary pond is selected by switch (1) rotation, and system selector switch (1) closes, and switch (2) is logical with switch (3), and above-mentioned two paths of threeway Push And Release are controlled still the same notion.
As among this figure, if gas is adopted multiple circulation Variable Control, to reach the needs that certain air feed rises liquid measure, promptly as adopting current difference control method: when low-level culture pool leads to switch (1) employing quantitative (crack) in secondary pond, its throughput rate amount is approximate must not reach greater than secondary pond (jar) and low-level culture pool synchronous boost, at this moment aerogenesis boosts to belong to and boosts slowly, the tolerance that is low-level culture pool supply secondary pond is less, and because switch (3) is defeated when using gas, but gas belongs to the moment amount of confessing, the flow of secondary pond output gas is confessed tolerance much larger than low-level culture pool, so the liquid of water pressure house (10) mostly draws in the secondary pond through water inlet pipe (), water pressure house (1) liquid descends.When switch (3) when stopping to use gas transmission, because of low-level culture pool pressure greater than the secondary pond, switch (1) continues gas transmission to the secondary pond and advances, the liquid the secondary pond in continues to rise to through rising pipe (8) water pressure house (9) of ground, secondary pond.
When implementing, above is to transfer to according to the crack amount of described switch (1): the discharge opeing flow velocity of secondary pond rising pipe is not opened because of switch (1) has tangible pulse ripple greatly for suitable, (if this illustrated that secondary pond pressure ratio low-level culture pool is pressed low a bit just) and adjust switch (1) during without gas at aerogenesis.
According to above control relation, another kind is, switch (1) goes to closes, and promptly as above-mentioned form, when on the aerogenesis during certain pressure, switch (1) opens wide, and makes low-level culture pool gas pulse secondary pond, and the liquid pulse flushing that the secondary pond must be pressed also can utilize stirs the secondary pond; During without gas, low-level culture pool secondary pond can gas UNICOM, switch during with gas (3) is opened, switch (1) cuts out and makes not UNICOM of low-level culture pool secondary pond gas, and switch (2) secondary pond and defeated control with device switch (2) this switch of gas UNICOM (1) surely containing multiple degree as: but above-mentioned ajar switch (1); But and also the same switch of Push And Release (3) of switch (1) in the revertive control of Push And Release phase; Switch (1) is promptly arranged by the pass---the instruction control scope of crack and standard-sized sheet, be flexibly or almost use the control device of rotary valve flow and reach the control requirement of the unidirectional raise-position of air pressure liquid.Especially it is even more ideal switch (1) to be carried out various automatic controls, particularly can establish the transmission trip switch (1) that the liquid level lifting moves according to water pressure house (10).As switch (1) can be flexible pipe spare, (hanging) established in flexible pipe spare lower end a float (12), the certain depth that float goes out to be hung under water pressure house (10) maximum water level is the above certain altitude of lowest water level line, promptly rise to when exceeding that float is unsettled to hang certain altitude when the water pressure house liquid level, switch (1) is to the gas transmission of secondary pond; And with gas one-level water pressure house (10) liquid small part back pressure low-level culture pool, when dropping to float, liquid level hangs in water pressure house, or liquid level is reduced to former suspension place of nearly float and is resetted, gas can not be from the logical secondary pond of flexible pipe spare (1), and one-level water pressure house () liquid is with entering secondary pond with gas from water inlet pipe (14) with gas secondary pond.These forms can be built and are the vertical propelling liquid of tower.
As high density organic sewage (thing) fermentation vat gases such as straw fermentations on the mountain region, advance low level (city, rural area) pond liquid to comprise the discharging of rising that can the hydraulic fluid liter hoists of the gas of other character.
Because " the high low level pond " inconvenience still described in " research " is useful for coventional type hydraulic type pond, so the system and device that is constituted with regard to this control novel method according to above-mentioned, awards the comparison of following produce effects: with " the two ponds of high-low pressure " promptly on hydraulic type ultimate principle basis.When example with 8m
3Low-level culture pool daily gas rate is 0.15m
3Chi Rong, gas production rate evaluation gas 1.2m
3, secondary pond factor of created gase is 0.05m
3, and 2m
3It is 0.1m that the secondary pond holds daily gas
3Gas production rate (hydraulic fluid amount), by the normal design water pressure house, its volume equals normal day generation 1/2 volume.The design of water pressure house (10) useful volume is at 0.6m
3More than, if adopt control method of the present invention, can change secondary pond volume and about 0.3, (can extrude ≈ 0.6m round the clock
3Left and right sides liquid, former pond " high-low pressure two ponds " institute's " research " volume of building of the volume ratio in secondary pond falls for a short time nearly 6 times thus, rises liquid (water) automatically and improves nearly 6 times on the contrary, and positive and negative (build less and have more) two kinds of benefit additions can be compared to liquid measure and rise than original technology and many 20-40 times.Building up said system just can have high benefit ground to build such secondary pond or be easy to box batch production production.It advance the secondary pond for low-level culture pool or more than three grades relay to rise liquid level be weight especially.
Fig. 2, be having built up gradient shape pond between low-level culture pool and secondary pond or secondary pond and the secondary pond, the place of being separated by of Chi Yuchi build lock, valve (17) or pipe broadcast connect control UNICOM, more than these forms, can the sewage that does not produce biogas be advanced, also available other gaseous tension relay advances liquid in higher position, thereby can reduce the pressure intensity of accepting of container.
They can mix the parts of liquid level in the liquid level controlled observation ponds such as " biology increases the ferment device " or outer exposed conduit in addition.Each pond of same UNICOM is pushed into air guide spool footpath and should equates, and the pipeline that communicates distance preferably equates.
From as can be known above-mentioned, former " research " as being beneficial to " high low level pond ", mainly water outlet realizes unidirectional control to low-level culture pool (6), and the little side of turnover bore is beneficial to operation; " the two ponds of high-low pressure " mainly are each self-supporting air pressure liquid of gas in low-level culture pool, secondary pond, a large amount of back pressure low-level culture pools of low-level culture pool water pressure house (10); So secondary pond voltage rise liquid liquid measure is few, this gas circuit control is to be used in " high low level pond ", and feature of the present invention can rise liquid in low-level culture pool gas propulsive two ponds mainly to control going out the airshed size and closing of airway (), and one-level water pressure house () liquid is supplied with the water inlet of secondary pond substantially.So low-level culture pool water pressure house () bore is () greatly.So that application popularization, again and water inlet pipe also can enter in the secondary pond and combine with flexible pipe and float, the mouth of a river is located in the secondary pond on the liquid level, so help the variation of low-level culture pool (liquid water inlet volume) liquid level and change.Then make the height and the low-level culture pool respective change of water-in.
Thereby founded special-purpose organic sewage and do not had the power consumption of adding, reverse raise-position blowdown system or comprise upstream discharges the pneumatic riser pipe step by step road formula relay of various liquid such as other sewage, and each pond (pipe) but return, dirty UNICOM connects the method and the configuration-system that advance (going out) material automatically that discharging or pond smpa pulse are washed lavatory, poultry.
The former achievement in research of the former relatively hydraulic type biomass pool self-circulation of the present invention has obvious improvement effect.

Fig. 3 is except that adopting Fig. 1,2 aforesaid methods, can also make former " the two ponds of high-low pressure " that are cited and make comparisons, " high low level pond " but enter the way of practicality, that must be furnished with it the hydraulic pressure movable guard exactly, can conveniently open cover to alleviate the difficult problem of the little inconvenient charging discharging of Inlet and outlet water bore shown in the civilian Central Plains figure, certainly it is better preferably to join " fully automatic hydrodynamic operator by anaerobic energy " described hydraulic pressure movable guard various ways, but this diagram technology 1,2 also water distribution press movable guard.
Identical (but gas control is without switch (1), because the water pressure house of Fig. 3 (10) can directly go back to the former pond of liquid (low-level culture pool 6) not as Fig. 1, Fig. 2 with gas the time than secondary formula (7) the water inlet water outlet form of the shape formulas that crouch in two of Fig. 2 pipes for this Fig. 3.Be that Fig. 3 aerogenesis or feed liquor (material) are right, rising pipe (14) discharge opeing give water pressure house (10) or directly row give the feed-pipe (9) (requiring decide) in next stage pond according to the difference of disposing of sewage, liquid advances groove (19) from water pressure house (10) and enters upper level high position pond---secondary pond (7) through water inlet pipe (13) again when with gas; Different is, and it adds in former " research " and is furnished with the hydraulic pressure movable guard (this form helps utilizing groove to penetrate with part in the pond, dark etc. as pressure limiting), movable guard (20) but be furnished with fixation means, before advancing thick shape solid materials or opening cover when slagging tap, the available air cock control of cover top conduit (5) that cover communicates with the pond is UNICOM not, in order to avoid pool gas leaks outside, gas in the cover is put used up then, then cover is broken away from fixation means.Like this, can the available again gas of aerogenesis in the pond, the discharging of not reloading the like this removable cover of avoiding breaking a seal is slagged tap and is become flat stopping production with stopping production.
Though the pool structure of Fig. 3 is different from secondary pond (7) shape among Fig. 2, but its circulation process route (form) is similar, it can be the water drain form equally, gate joint control system at the bottom of four kinds of flow line 1 ponds is arranged, the 2nd, rising pipe (14) goes out, water inlet pipe advances, reverse up-flow (or other establishing, and self carries out technology such as fully automatic working circulation in this pond), the 3rd, it is dirty step by step that rising pipe (14) goes out to enter next stage pond opening for feed (9), the 4th, rising pipe or other are considered the clear liquid body and are supplied with water pressure house (10), (slime flux mouth (pipe) wants one-level more roomy than one-level by water pressure house overflow step by step downwards, to receive the increase step by step of downstream circulation) preferably be provided with opening for feed (8 as Fig. 1,9) supporting form, excessive cleaner liquid mouth (19) is defeated by water pressure house (10-11-12), fall in the supply pool than strong sewage, this form can independently be put its (8) and be carried out the shunting of removing contamination on the ground.If water pressure house is built in as concentrating (circumference) Yu Chiding among Fig. 3, can establish hollow ring recess cover in addition, cover covers within the water pressure house, movable guard (20) or comprise, outside the rising pipe, the foul smell of avoiding sewage, adopt longer water pressure house to link to each other among Fig. 2 between secondary pond (7) if be same as, but can be top compact part part sealing on the water pressure house, the head and the tail dividing plate also should award certain depth between the water channel of sealed part is pressed, when should use up gas to ensure still can water seal biogas, and on water pressure house (10) sealing top, set up airway in suitable place.
They should notice that common place is that the parallel relation that flux should be noted pressure and circulation is controlled in line-spacing, pipe circulation footpath, and reach the corresponding discharge relation of overflow liquid at different levels.
The effluent sewerage that is constituted is along the reverse process form, it can infiltrate the technology part of " fully automatic hydrodynamic operator by anaerobic energy ", with and wait biology, physics, chemical technology method, the overflow port of water pressure house wall (pipe) can be through the liquid of filtering, digestion with top, the following water footpath mouth of the valve during the water pressure house partition wall, bore expands with the amount of downstream sewage, and the collection chamber on the water pressure house is as the outfall sewer top in case of necessity.They can be that wherein, their water pressure house (10) both also had been the linkage section of the pipe of outfall sewer as the form in " high low level pond " (" the two ponds of high-low pressure ").
Fig. 2 and Fig. 3 have following useful form:
1, play anaerobic-aerobic fluidization treatment sewage, to the favourable staging treating that both distributed of digestion process situation, system flows back to and receives or utilization again, reduces scale of investment again widely.
2, the source shunting of removing contamination reduces and handles volume, improves fermentation concentration.Avoid again rainwater (my god) unprocessed dash (band) of sewage gone into river pollution.The shunting owing to remove contamination even enter again in the pond after having 3-4 digestion zone industrial sewage to go into water pressure house in the pond, can not exert an influence to anaerobic fermentation zone.
3, overcome present water drain with (asking) out of sight, out of mind and following aqueous vapor body water body has directly produced the stench of air and well water is contaminated
4, utilize that anaerobism power is contrary tries hard to recommend into that the sewage raise-position is thrown into high-order intermountain, plant water, with fertile or be circulated in the flushing lavatory and hold field etc.
5, can utilize gate respectively or unified control (as gas (move) gate valve of available " fully automatic hydrodynamic operator by anaerobic energy ", " energy of flow is controlled dynamic force generating unit more ") open or close pulse pond hypostasis), utilize dirt in the pond save up strength can or the actings such as release drive water turbine of rising potential energy.
6, comprise can not or the sewage of less product biogas also can establish airway and insert the below, pond, the implementation gas mixing is mixed, and the reverse propelling of sewage, accomplish to kill two birds with one stone as utilizing certain season (time) electric power to fill surplusly, be power conversion gas or biogas compression cycle input native system hydraulic fluid raise-position digestion, accumulation of energy, water reclaimed.The street water drain can be joined this system, if when pond (6-7) should not be joined in the position, can be assigned under the buildings field of razor clam barnyard, is led in locating as water drain by water pressure house and joins with other water pressure house etc.
7, native system can be connected in rivers, and the rivers water source is used the Tilly atmospherically
8, it also adapts to and comprises basin recess configuration, but Dan Chi and single pond also adapt on island with cogroup pond relay outfit ... along the river, river, trench city (road) is littoral is equipped with.
Fig. 4 section mainly is: adopt the anaerobism forms with water drain (water pressure house) most areas (10-11-12), it also can be an anoxic ditch form to be applicable to Fig. 2, Fig. 3, respectively adapted or do not add and join methane-generating pit (6,7) and have the anaerobism sewer line of one's own.If top (side) of pond (6 or 7) is to carry out to press oxygen formula water drain, in order to make water drain anaerobism section partly become effective water pressure house, can lead to gas hood (23) (seeing appended drawings 2) to the gas of methane-generating pit through on-off control, by gas hood again the airway (5) on lead UNICOM this Fig. 4 top make winner pond (6-7) when gas hood gas transmission (using gas), impel water pressure house (10-12) that pond (6-7) infused, at this moment, and gas hood (23) must be given road under water (water pressure house 10-12 gas transmission maybe can main pond (6-7) and their the direct intercommunication of water pressure house gas separately), in order to avoid the water drain anaerobism partly produces vacuum and calms the anger and can not fail during the gas transmission of pond (6-7), each volume of water drain among the figure, area should and be designed by each parameter of the water yield under the plumbing according to hydraulic type biomass pool ultimate principle technology.Each supports oneself the pond, also can join to be merged into bigger defeated streaming system.
