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.
