Abstract

The utility model discloses a methane gas pool with both try and wet pools. The utility model is characterized in that the structure of the pool is the try and wet pools are combined together up and down. Combined with peculiar fermentation process, the methane gas pool has the advantages of labor saving, convenient management, and high factor of created gas. The methane gas pool can banlancedly create gas with a long time. The methane gas pool can be produced in the factory in batch by the materials of steel, rigid foam, glass fiber reinforced plastics, etc. The utility model can be used as a miniature methane gas pool for families, or be expanded to a relatively large-sized methane gas tank which supplies the gas intensively.

Description

Methane gas pool having both try and wet pool

The utility model relates to a kind of methane-generating pit of doing, wetting dual-purpose.

The methane-generating pit that is adopted in the prior art mostly is hydraulic type biomass pool.Ubiquity difficult deslagging, material come-up crust, Chi Rongda (generally need 6～10M ³), the low (0.2M of factor of created gase ³/ M ³/ day about) etc. problem.Though it is high slightly to do the fermentation factor of created gase, owing to feed intake in batches, is difficult to keep the long-run equilibrium aerogenesis.And upflow sludge blanket only is applicable to the sewage fermentative processing of low concentration.

Task of the present utility model provides and a kind ofly does, the upper and lower novel pool-type structure that combines in wet fermentation two ponds, in conjunction with distinctive zymotechnique, and factor of created gase height not only, and can keep balanced aerogenesis in the long period.The utility model both can be used as the small-sized methane pond of using at the family, also can expand as and concentrate the relatively large methane-generating pit that gas is used.

The methane-generating pit of doing, wetting the fermentation dual-purpose described in the utility model, it is to be cascaded by upper and lower two ponds.Upper storage reservoir can utilize organic waste such as weeds, Stalks Rod, excrement slag, rubbish to do fermentation all on the ground.The big portion of lower storage reservoir is embedded in underground, can utilize the fermentation of wetting of people, animal ight soil.

This methane-generating pit upper storage reservoir constructional feature is that the pond is shallow, mouthful big, input and output material convenient, and can completely adorn, and makes full use of pool volume, in addition owing to upper storage reservoir all on the ground, also can make full use of solar radiation and heat.After acid was produced in the upper storage reservoir hydrolysis, its acid solution can flow into lower storage reservoir by pipeline, like this, because the acid solution of upper storage reservoir is in time discharged, not only helped the dried fermentation gas of upper storage reservoir, and flowed into lower storage reservoir as feed liquid, also can promote the lower storage reservoir fermentation gas.

The big portion of the lower storage reservoir of this methane-generating pit is embedded in underground, its ight soil is to become the higher excrement slurry of concentration after filtering through filter plate and the inflow lower storage reservoir, therefore need not big discharging, only discharge the top waste liquid during discharging from the gravity flow of flash pipe, and the fermented liquid that will be enriched with a large amount of methanobacterias is retained in the pond for a long time, play a part Sludge Bed, thereby make lower storage reservoir have high loading, high efficiency performance.The biogas pressure that the utilization of lower storage reservoir liquid manure itself is produced through communicating pipe liquid manure being sprayed in the upper storage reservoir of center, two ponds, thereby quickens to blend fermentation gas under the upper storage reservoir sour water.

Advantage of the present utility model is Chi Tixiao (cubic capacity 2M ³About), two ponds are upper and lower in addition is cascaded, and takes up an area of to lack, and cost is low.Materials such as this pond can be with steel, mould firmly, glass reinforced plastic are produced in batches in factory.This pond has the performance of kinds of processes type, is dried fermentation vat as upper storage reservoir, is again the acidification pool of two-step fermentation simultaneously.Lower storage reservoir be wet fermentation vat be again the product methane pond of two-step fermentation.In addition, owing to adopt zymotechnique preferably, the feed liquid in upper and lower pond can be recycled, and water consumption is less.And do not have come-up crust phenomenon, the natural pond slag water content of upper storage reservoir is few, removes and is convenient to the land for growing field crops fertilising, and Shang Kezuo cultivates the matrix of mushroom.Natural pond, upper strata liquid after the lower storage reservoir fermentation can utilize to the manure storage pond by the flash tube drainage again, can be discharged into also that feed is made in the pond or fertilizer is made in the vegetable garden.Another advantage of the present utility model is a convenient management, saves the labour.General three of upper storage reservoir comes the moon to reload once, and can rotate by subregion in the pond, and lower storage reservoir advanced to go out for a short time once in about 5～7 days for a short time, and input and output material all can flow automatically.

The utility model is through the outdoor normal temperature fermentation test of half a year, and effect is comparatively desirable.Lower storage reservoir aerogenesis peak period only, average factor of created gase is 1.1～1.96M ³/ M ³Liquid/sky is up to 2.3～2.5M ³/ M ³Liquid/sky.Our experiments show that as long as in time reinforced, Chi Wen is more than 15 ℃, factor of created gase can remain on 1M ³/ M ³Liquid/more than the sky, about first quarter moon after October, pond temperature drop to 10 ℃, average aerogenesis 0.58M still ³/ M ³Liquid/sky.The dry-matter (TS) of the material of throwing calculates according to May 13 to 15 days October, and the biogas turnover ratio of material is 0.38M ³/ kg, TS.

Embodiment of the present utility model 1 is described as follows in conjunction with the accompanying drawings:

Accompanying drawing 1 is for doing, wet dual-purpose biomass pool structure sketch.

1 of accompanying drawing 1 is the promptly dried fermentation vat of upper storage reservoir, and 2 is the promptly wet fermentation vat of lower storage reservoir, and 3 is that the manure storage pond is again that ight soil is disposed the pond, 4 are the upper storage reservoir lid, and available lightweight material is manufactured, and 5 is water sealed tank, 6 is barrier, available steel plate or material such as mould firmly and manufacture, the aperture of 2～3mm diameter that gathers on it.7 is the dirty pipeline of acid solution of upper storage reservoir, and 8 is acid solution pipe pipe valve.14 for upper storage reservoir leads to the removable cover of lower storage reservoir, and diameter is about 50 centimeters, so that lower storage reservoir is overhauled.12 lead to communicating pipe of upper storage reservoir, 6～8 centimeters of calibers for lower storage reservoir.13 are communicating pipe nozzle upward, and its form can be that taper shape also can be a duckbill.9 is the airway in upper and lower pond, and 11 is pipe valve on the airway, and 10 is under meter.15 is lower storage reservoir flash pipe, and available lucite pipe is manufactured, and pit level is observed under the double as.17 is bulkhgead gate, and with plank or mould making firmly, 16 is Zha door Qi Bi Rod.18 is the liquid manure inflow pipe.19 is filter plate, evenly opens the aperture of 3mm diameter on it, in order to avoid impurity enters aperture, 20 is the ight soil inflow pipe.
