Description
Technical field
The utility model relates to a kind of methane-generating pit, especially adopts human or animal's movement and other organism to make the equipment of biogas and fertilizer.
Background technology
One of methane-generating pit of promoting in China rural area is the structure that adopts round shape hydraulic biomass pool type at present, M3 round tube type hydraulic biomass pool with national standard is an example, the constructional feature of its pond type is 1, main pond belongs to circular, big with respect to its capacity of other shapes (as oval, square body), wall is stressed evenly, the pond body is firm relatively, and cloth is even after the charging, and it is more abundant to ferment; 2, adopt hydraulic type, its top, main pond gas dome complete closed, discharge room (being commonly called as secondary pond) be discharging place be again water pressure house.Along with the continuous generation of biogas, liquid level increases between main pond.When using gas, biogas reduces, and the feed liquid of water pressure house is returned in the pond again.Like this, the string back and forth of part feed liquid is moving, causes the variation repeatedly of hydraulic pressure, reaches the purpose of storing and discharging biogas.
The major advantage of above methane-generating pit is 1, can inflates the supporting capacity of utilizing soil, and pond body stress performance is good; 2, be suitable for loading multiple fermentation raw material (swine excrement, crop tangerine bar etc.); 3, be convenient to frequent charging, pig house, feces of toilet can both be swept into pond at any time; 4, all contact with soil around the body of pond, insulation has certain effect to the pond body.But there is following shortcoming: 1,, the stable of pond body intensity and light fixture, kitchen range efficiency of combustion all had adverse influence with improving because air pressure changes repeatedly; 2, owing to there is not whipping appts, scum silica frost crusts easily in the pond, is difficult to fragmentation again, so the utilization ratio of fermentation raw material is not high, pond appearance factor of created gase is on the low side, and (only be 0.15M every day
3/ M
3About); 3, owing to have only a fermentation vat,, can not fully ferment when charging is frequent, when inlet amount is big, some raw materials are just overflowed without fermentation.
Summary of the invention
The purpose of this utility model is the shortcoming at existing round tube type hydraulic type biomass pool existence; provide a kind of raw material availability higher; it is more abundant to ferment; aerogenesis is more stable; factor of created gase is higher, and air feed is more even, helps protecting the pond body; can effectively solve scum silica frost crust, residue deposition problems, three grades of round tube type hydraulic type automatic sludge discharge methane-generating pits that work-ing life is long.
The utility model is provided with at least 2 Primary Fermentation ponds and at least 2 water pressure houses, the alternate successively series connection of Primary Fermentation pond and water pressure house is communicated with, the Primary Fermentation pond is a round shape, establish opening for feed in the 1st Primary Fermentation pond, in the end establish overflow port or discharge port on 1 water pressure house, the gas dome on top, Primary Fermentation pond sets out gas port respectively, and the air outlet picks out tracheae.Chi Gai can be established in top in the Primary Fermentation pond, can establish valve in the air outlet of top, Primary Fermentation pond gas dome, and inner bottom part can be established curved wall in the Primary Fermentation pond, and pond slanted floor degree is made as 3 °～5 °.The escape pipe parallel connection of top, Primary Fermentation pond gas dome.Said Primary Fermentation pond and water pressure house can be established 3 respectively.
Compare with existing methane-generating pit, the utility model has the advantages that: 1) raw material availability improves, and it is more abundant to ferment.With 1 fermentation of original 1 charging, change into 1 charging and repeatedly ferment, make fermenting raw materials more thorough.2) aerogenesis is more stable, and factor of created gase improves.Owing to do not run off substantially through the natural pond liquid heat that the upper level fermentation vat changes over to, keeps more stable leavening temperature, make aerogenesis stable and improve factor of created gase, its pond appearance factor of created gase can be from original every day of 0.15M in south
3/ M
3Bring up to 0.3M every day
3/ M
3More than.3) air feed is more even, and it is more stable to burn.Because the escape pipe parallel connection of a plurality of fermentation vats, air pressure can not rise and fall sharply and quickly during air feed, can guarantee that air feed is even, and light fixture, kitchen range efficiency of combustion are relatively stable.4) be beneficial to protection pond, Primary Fermentation pond body, guarantee that pool wall is firm.Air pressure big rise and big fall when having avoided air feed or discharging, variation repeatedly, the impact that bay wall is not constantly changed by hydraulic pressure.5) effectively solve scum silica frost crust, residue deposition problems, prolong methane-generating pit work-ing life.Owing at the bottom of the pond, be provided with curved wall, be provided with certain obliquity at the bottom of the pond, so feed liquid can be rolled automatically after the charging, fully stir, can in time destroy the crust layer, in time some solid residues are led out simultaneously, avoid the residue alluvial.6) be convenient to a large amount of chargings, be suitable for big-and-middle-sized plant and use.Because the series connection of a plurality of Primary Fermentations pond is communicated with, capacity increases, and increases possibility for a large amount of chargings.
