Description
Technical field
The utility model relates to the methane-generating pit technical field, is specifically related to the barrel-shaped methane-generating pit of a kind of novel Novel flat.
Background technology
The common advantage of GB/4750-2002 " domestic methane tank standard collective drawings ", " 04-B small-sized efficient methane-generating pit " trial run scheme, southern biogas production and comprehensive utilization technique, biogas production work training teaching materials: 1. facilitate the pump drainage biogas residue and biogas liquid, 2. build the pond cost lower, after 3. ight soil, stalk etc. being processed, produce biogas.Shortcoming: 1. the gas leakage of leaking (bay wall body seepage, construction there is not uniform mixing, no vibration and of poor quality, the factors such as removable cover and pipe fitting poor sealing cause gas leakage).2. air storage insufficient space, pressure are little, and the peasant can be with biogas amount (every day 0.2-0.5m very little
3the family that complete less than is 3-5 mouthfuls is 1-1.5 m day by day
3the biogas consumption; Only have tolerance when foot in dog days could be by the natural pond hydraulic pressure between air storage to 20-40 centimetres of water pressure houses, have biogas can with).3. floor space is large, and pond shallow (fermentation vat is grown 2.7 meters, dark 1.7 meters and is contained 20 centimetres of removable covers), volume is too little, and can not store too many raw material does not just have more dry-matter to carry out voluminous biogas.4. (have reinforced or only add a defective material, do not stir or stir inhomogeneous, and the bed thickness that causes crusting reaches 20-40 centimetres, the thickest reaches 1 meter in the not good at management or no management of peasant; Slagging-off once in 2 years, can cause biogas yeast perhaps very little, for a long time all can not normally produce biogas).5. " three natural ponds " comprehensive utilization is few, and publicity understanding not.
