Technical field

The utility model belongs to a kind of large vol methane-generating pit technology.

Background technology

Existing methane-generating pit generally is family pond type, and low capacity pond type is adapted to peasant family and uses.For the heavy livestock feedlot, just inapplicable.If according to home-use small-sized methane pond, just need build a lot of, the one, uneconomical, the 2nd, floor space is big, and the 3rd, manage and use the gas inconvenience.In addition, methane-generating pit is in service can automatic shell-breaking, and to prolong input and output material methane-generating pit technology be a kind of through practice for many years, the moulding methane-generating pit of operational excellence to the methane-generating pit technology that increases gas deliverability as helping automatically.But large methane tank prevents crust, and to improve gas production rate, the biogas material advances the processing the pond before, and the timely discharge of natural pond slag and natural pond liquid etc. etc. still is a new problem in the methane-generating pit.

Summary of the invention

This practical purpose discloses a kind of tunnel like exactly and helps automatically and prolong the input and output material methane-generating pit.The technical problem that solves is the fermentative processing in advance of the raw material before the pond into, and charging is concentrated relatively and natural pond material in the pond produced and impacts tipping effect; Biogas is concentrated and is convenient to carry, and natural pond liquid can be concentrated under the liquid pressure in the pond voluntarily in the methane-generating pit, and the natural pond slag can be pushed and concentrate by liquid buoyancy in natural pond in the pond, so that processing etc.

Concrete scheme is as follows:

A kind of tunnel like is helped automatically and is prolonged the input and output material methane-generating pit, and by charging pond, material-output tank, the material pre-treatment of fermentation vat and natural pond, transmission ﹠ distribution gas etc. partly constitute, and key is that the pond system becomes by the charging pond through fermentation vat to material-output tank, from up to down the tunnel like of Qing Xieing; Oral area is the charging pond, and the middle part is a fermentation vat, and foot is a material-output tank.A U-shaped feed-pipe is installed between charging Chi Kou and fermentation vat; Sidewall has the sediment relief outlet in the bottom of material-output tank, and wall is equipped with the sediment pumping line outward; Be positioned at liquid position, natural pond sidewall in the material-output tank middle and lower part and have natural pond liquid relief outlet, wall is equipped with natural pond liquid dispatch pipe outward.The material-output tank mouth can also be made and be convenient to the tubular outlet that directed voluntarily inner chamber of discharging is a curved channel under the hydraulic action in the pond of natural pond slag, and the cross section of curved channel is square or circular, realizes the purpose that the natural pond slag is discharged under the hydraulic action in the pond voluntarily.

In addition,, be connected with the charging pond, be used for doing acidifying and promptly diluting fermentative processing in advance advancing natural pond material before the pond by gate at the deposit equalizing tank of charging pond peripheral hardware in respect of a capping state.Make again the time simultaneously, concentrate the natural pond material of relative quantity, fermentation vat is had the impact effect of long period greatly, effectively solve fermentation vat crust problem to the fermentation vat charging.

Just can be made into a kind of tunnel like according to such scheme helps automatically and prolongs the input and output material methane-generating pit, because the pond system becomes tunnel like, fermentation vat has long bigger space, the natural pond material that holds is many, in addition, has used the U-shaped feed-pipe between charging pond and fermentation vat, natural pond material through anticipating in the feasible deposit equalizing tank is after playing lock, concentrate to enter in the fermentation vat process, produce the effect of impacting fermentation pond material, avoided fermentation vat top layer crust problem.Because fermentation vat is in the position of tunnel shape obliquity maximum, in the pond sediment can be rapidly along the pond underflow to material-output tank the bottom wait to discharge.And the natural pond material concentrates on fermenting tank for fermentation under the effect of liquid suspension power in the pond, and the biogas of generation is being concentrated to Chi Ding top, use to be sent.Natural pond slag side after the fermentation ends is gathered in the top between material-output tank, discharges from natural pond slag discharge port; Natural pond liquid is in the material-output tank middle part, is sent by natural pond liquid dispatch pipe; Settling concentrates on the material-output tank bottom, is sent by the sediment pumping line.Like this, make this kind tunnel like help automatically and prolong the input and output material methane-generating pit that can move aerogenesis continuously, this separate type deslagging, discharge opeing and the sedimental whole process of row are all carried out in not influencing the methane-generating pit works better.Adapt to large-scale feedlot and utilize excrement of animals or municipal wastes to be converted into biogas energy, reduce production costs, a technology of increasing income.

Embodiment

Below in conjunction with accompanying drawing,, scheme is specified as embodiment.

Example one, with reference to Fig. 1, described big obliquity tunnel like is helped automatically and is prolonged the input and output material methane-generating pit, the important feature of its structure is 5 to cover 7 parallelly with the pond at the bottom of the fermentation vat, from up to down tilts with same obliquity, its section shape is like a tunnel.The lower end is exactly a material-output tank 3, and the bottom is convenient to the concentrated sediment that flows to of sediment and is exported for to export curved concave surface to sediment, is pumped into outside the pond.Charging pond 9 is in a high position outside the wall of fermentation vat 6 upper ends, the two has round mouth, a U-shaped feed-pipe 12 is installed at the round mouth place two ponds are communicated with, and caliber is according to size and the natural pond material supply situation design and the manufacturing in pond.Lay in equalizing tank 11 and tightly be connected with charging pond 9, it is a chamber that charging Chi Kou is connected with deposit equalizing tank middle part, and the two installs a gate 10 controls, when having only charging, and ability starting gate 10.The inlet of deposit equalizing tank is collected with excrement of animals and is carried canal to be communicated with.The excrement of animals of collection is focused at any time concentrate in the deposit equalizing tank and do pre-treatment, play the initial fermentation acidizing effect.In fermentation vat top cover 7 position perforate topmost biogas pneumatic tube 8 is installed.Because fermentation vat 6 is tunnel like, upper space is less, and promptly the air storage chamber capacity is little, so the biogas of output will be delivered to 8 in the outside gas storage equipment from managing at any time in the pond.Be this kind pond type, need have outside gas-holder or storehouse.Open the sediment outlet in discharging pool wall bottom, wall is installed a sediment pumping line 1 outward; Open the waste firedamp liquid outlet at pool wall place on the lower side, liquid position, the natural pond of material-output tank, a natural pond liquid dispatch pipe 2 is installed, pump lift should consider that settling is requirement in the material-output tank fully extracting out, is installed in the material-output tank mouth deeply according to the pond.Material-output tank lid 4 has only material-output tank 3 sealings when needing the natural pond on taking-up material-output tank top slag, just opens Chi Gai and slags tap.The capacity of the methane-generating pit of present embodiment is 200m ³Pump lift is 15m, and fermentation vat slanted floor degree is generally greater than 20 degree.

Example two, with reference to Fig. 2, at the bottom of the fermentation vat 5 obliquitys 10 the degree about, material-output tank 3 is also at lowermost end, the pool wall upper shed at the bottom of the material-output tank is positioned at the pool wall upper shed that the natural pond liquid level is put, and sediment pumping line 1 and natural pond liquid dispatch pipe 2 are installed respectively, pump is installed on the end face of pond.The upper space of fermentation vat 6 is the gas storage pond, by near the perforate material-output tank 3 pneumatic tube 8 is installed at the pond end face, delivers to place with gas requirement.Charging pond 9 is adopted and is helped the structure of prolonging the input and output material methane-generating pit automatically, be that half of charging pond is suspended from the upper space of fermentation vat 6 ingress, second half then is communicated with by gate 10 with deposit equalizing tank 11, and it is a chamber that charging Chi Kou also is communicated with deposit equalizing tank middle part, and the deposit equalizing tank also is in a high position.The processing of its fermentation working process and natural pond slag, natural pond liquid and sediment is all identical with example one.

Above-mentioned two examples, deposit equalizing tank 11 were both made acidification in advance to the natural pond material of collecting, and the while filters deposition foreign material such as sand, stone, soil again and removes, and avoids entering in the fermentation vat 6, had guaranteed natural pond material quality and the workload that reduces the material-output tank cleaning.

With reference to Fig. 3 or 1,2,5 shapes of making obliquity at the bottom of the pond of methane-generating pit, it is square or circular arc tubular outlet that its material-output tank 3 export department's inner chambers are made cross section, makes the natural pond slag in the pond under the action of hydraulic force, the directed discharge.A rotation door-plate 13 is installed in the tubular exit.Like this,, make that the natural pond slag after fermentation will be pushed to the material-output tank oral area voluntarily, and under the internal hydraulic pressure reactive force, oral area door-plate 13 is pushed open that the natural pond slag is sent automatically, realize that the manpower of exempting from of natural pond slag is slagged tap because fermentation vat 6 and charging pond 9 are in high relatively position.When not arranging the natural pond slag, then close automatically.
