Shown in Fig. 3 b, Fig. 3 c, ground between input and output material between the inside and outside circular orbit in arc feed bin chassis, the above back of the whole 1m of intensification downwards bunching is that doline forms slag deposit buildup pond, natural pond, is used for the useless natural pond slag that deposit buildup is taken out of from the natural pond slag scraper plate of being installed by the feed bin chassis between aerogenesis gas storage; Flare opening at the bottom of the pond has PVC (or other corrosion resistant materials make) blow-off pipe to connect, and the logical upper ground surface of blow-off pipe docks with the water-in of slush pump, the rising pipe feeding slag liquid separate tank of slush pump.

It between aerogenesis gas storage the topmost integral part of annular methane-generating pit group, material fermentation here in natural pond is decomposed production biogas and is stored, capacity (quantity of holding feed bin) in the annular methane-generating pit group between aerogenesis gas storage is can be anisometric, because, in the large-scale annular methane-generating pit group, different ring arc methane-generating pits, can select to add different classes of natural pond material, natural pond material difference then the aerogenesis cycle also different, the aerogenesis cycle is again a decision condition of holding feed bin quantity between the gas storage of decision aerogenesis, so, different ring arc methane-generating pit in the annular methane-generating pit group, can expect and select to drop into different classes of natural pond by regulating the quantity that has feed bin between aerogenesis gas storage.

Shown in Fig. 3 a, between each aerogenesis gas storage of annular methane-generating pit group, Steel Concrete arc caping vertex near divider wall between input and output material, be embedded with the above stainless steel escape pipe of diameter 15cm, and the escape pipe between adjacent aerogenesis gas storage, link along inner arc wall between input and output material or outer arc wall, be between each aerogenesis gas storage of annular methane-generating pit group, not only Xia Mian natural pond liquid is UNICOM, and the biogas on top also is UNICOM, like this, it is identical just making the air pressure between aerogenesis gas storage all in the annular methane-generating pit group, below the liquid level of natural pond liquid also be same level; Both can unify to dispatch the outgoing management of biogas, also can unify the production management of annular methane-generating pit group.

Shown in Fig. 3 c, bottom between all aerogenesis gas storage of full annular methane-generating pit group and between input and output material, circle wall and cylindrical wall in pasting, the above stainless steel temperature adjustment pipe of diameter 15cm respectively is installed, also can only the temperature adjustment pipe be installed at interior round wall, because, the feed bin chassis is bigger than cylindrical wall apart from the gap of interior round wall, have more installing space, on the cylindrical wall, install and to move the cylindrical rail wheel under the feed bin chassis in suitably, to abdicate the space that the temperature adjustment pipe is installed; The boiler that temperature adjustment pipe and methane-generating pit are outer or the heating pipe line of heat power plant are connected, and during liquid temperature decline between aerogenesis gas storage, the wide hot water of available boiler or thermoelectricity makes liquid temperature interior between aerogenesis gas storage reach the temperature of best aerogenesis at temperature adjustment pipe internal recycle.

Reach on the arc caping outside the whole inside and outside round wall of annular methane-generating pit group, attached subsides bag can be kept the temperature in the annular methane-generating pit group by the foam heat-insulation layer more than the thickness 10cm, reduces the temperature adjustment expense.

The hydraulic pressure of annular methane-generating pit group is transferred liquid pool, both can be positioned at the round formula of annular methane-generating pit group ring inside shown in Fig. 3 a, also can be the external circular type that is positioned at annular methane-generating pit group ring outside; The hydraulic pressure of annular methane-generating pit group transfers liquid pool to select interior circle formula or external circular type, the size that depends on the annular methane-generating pit group total area, circle formula hydraulic pressure is transferred liquid pool in can selecting when the total area of annular methane-generating pit group is less than or equal to area round in the ring, when the area of annular methane-generating pit group greater than ring in during the area of circle, can only select external circular type hydraulic pressure accent liquid pool; No matter interior round formula or external circular type, hydraulic pressure are transferred all levels of the Chi Ding of liquid pool and the feed inlet and outlet between each input and output material, the bottom level of divider wall at the bottom of the pond and between each input and output material; On the outer arc wall between each input and output material, it is above and transfer UNICOM's mouth of liquid pool bottom level with hydraulic pressure all to be reserved with diameter 40cm, makes hydraulic pressure transfer the water of liquid pool freedom to go out, to go between input and output material swimmingly; Hydraulic pressure is transferred the water capacity of liquid pool, be no less than the above capacity summation of divider wall bottom water horizontal line between all the aerogenesis gas storage of annular methane-generating pit group.

The slag liquid separate tank of annular methane-generating pit group shown in Fig. 3 a, is distributed in each near on the caping between the ring arc aerogenesis gas storage of interior circle wall one side between input and output material (also can be distributed in the Chi Ding that external circular type hydraulic pressure is transferred liquid pool).Slag liquid separate tank is shown in Fig. 3 d, be square or rectangle (A is that vertical view, the B of slag liquid separate tank is that front view, the C of slag liquid separate tank is the side cutaway view of slag liquid separate tank), the pond slanted floor is transferred liquid pool and is left water outlet 1 to hydraulic pressure, at the bottom of the pond, prop one deck and pond base slope top level and be covered with the skeleton construction sieve plate 2 of spacing 10cm, diameter 2cm circular hole, the stone layer 3 that sieve plate upper berth one deck particle diameter 3cm is above, thick 10cm is above, top shop one deck of stone layer or the close net 4 of which floor 60 purpose polyethylene can reach the filtration purpose; The degree of depth of slag liquid separate tank (containing the stone layer) should be about 60cm, and capacity is less than the capacity in slag deposit buildup pond, natural pond; Natural pond slag and natural pond liquid when slag deposit buildup pond, natural pond, sent into slag liquid separate tank by slush pump together after, natural pond liquid sees through close net and stone layer, goes into hydraulic pressure through the pond underflow of slag liquid separate tank and transfers liquid pool, the natural pond slag is then stayed slag liquid separate tank, removes behind the liquid of the clean natural pond of drop.

The structure of the annular feed bin group of annular methane-generating pit group and the annular feed bin group of hopper and circular methane-generating pit and hopper is just the same with configuration.Just, in the feed bin group of the annular methane-generating pit group of forming by N feed bin, represent the numeral of feed bin quantity N to become greatly; Because the radius of the circular methane-generating pit of the radius ratio of annular methane-generating pit group is a lot of greatly, so the length on the inside and outside arc limit of interior feed bin of annular methane-generating pit group and hopper is approaching; In the annular methane-generating pit group, the interior axle rail wheel of feed bin group is that the interior round wall of embracing annular methane-generating pit group turns round as interior axle; Annular feed bin group is installed between each aerogenesis gas storage of annular methane-generating pit group and the bottom between input and output material shown in Fig. 3 b, Fig. 3 c.
