Described overflow weir 2, when being charging implementation strong inverse flow, natural pond slag, natural pond liquid are entered by feed-pipe 8, through elbow 5, broken shell pipe 9, natural pond liquid is distributed to 16 central areas, two stage fermentation pond uniformly through the natural pond liquid level, through cloth wall 13 and threeway 14, is discharged by discharge nozzle 12, further behind the fermentation vat 17, enter the second order fermentation pond by overflow weir 2 and carry out fermentation gas again, form multistage fermentation, multistage decrement digestion.
The bottom of described elbow 5 is provided with bidirectional-reflux hole 10, is when pressure rises and decline feed liquid flow, and feed liquid can be two-way flow and be unlikely to elbow 5 is stopped up in bidirectional-reflux hole 10, simultaneously to two stage fermentation pond 16 additional a part of feed liquids.
The middle and lower part of the middle part of described broken shell pipe 9 and feed-pipe 8 is provided with shroud ring 6 respectively, and shroud ring 6 fixes with broken shell pipe 9 and feed-pipe 8 respectively by bolt 7, and the shroud ring 6 on the described broken shell pipe 9 links to each other by wireline 19 with shroud ring 6 on the feed-pipe 8.
Described removable cover 3 is oval slot type removable cover, and removable cover 3 is provided with sealing groove 21 with arch 4 contact positions, and described removable cover 3 is installed on the methane-generating pit skylight opening, install easily, and convenient disassembly, water does not moisten, no later stage maintenance.
The bottom of described discharge nozzle 12 is provided with threeway 14, has both sealed discharge nozzle 12, and the straight tube straight cutting produces the wander away phenomenon of methane of unit cross-sectional area, two-way the entering of liquid natural pond, natural pond slag, has increased amount of flow again.
Described elbow 5 and broken shell pipe 9, it is that charging is returned certain height again with V font elbow, with the mobilization force of feeding liquid itself, goes out through broken shell pipe 9, and liquid level crust in two stage fermentation pond is abolished at any time.
Described cloth wall 13 is to work as feed liquid by broken shell pipe 9, after the liquid level broken shell, feed liquid is distributed to 16 central areas, two stage fermentation pond, feed liquid continues to increase, and by cloth wall 13 clothes, material is distributed to the outlying area in two stage fermentation pond 16 when the generation nature flows, again through the outlying area of cloth wall 13, assemble to discharge nozzle 12, be discharged in next step fermentation vat by discharge nozzle 12, finish a loop cycle through threeway 14.
Described two stage fermentation pond 16, but unit independent operating, but multiple-unit combination operation again, operation also can spread all over the place.
Described two stage fermentation pond, flow lifting type is semicontinuous to feed intake owing to having taked, thereby the bacterium material mixes timely, has improved factor of created gase.
In two stage fermentation pond 16 heating tube can be installed, it can utilize various thermals source, as the hot water of sun power, the hot water and the various life waste heat of generator.Fermentation vat for the unit independent operating can install U type pipe additional, realizes pneumatic automated cycle, for installed additional the micro computer and the process pump of multiple-unit operation, effectively controls charging, realizes that by charging strong inverse flow stirs operation automatically.
Natural pond liquid operation is implemented
Feed liquid is entered through elbow 5 by feed-pipe 8, the feed liquid major part is to 9 operations of broken shell pipe, a very little part is in bidirectional-reflux hole 10 is discharged to two stage fermentation pond 16, in most of broken shell pipe 9 operation, going out broken shell pipe 9 breaks through the crust that floats on the zero water level line 20, feed liquid is distributed in simultaneously the central area in two stage fermentation pond 16, at this moment, feed liquid expects to mix mutually with the bacterium in the two stage fermentation pond 16, when feed liquid continues to be increased under the effect of cloth wall 13, bacterium, material distributes around the pond uniformly, the periphery of little by little assembling cloth wall 13 is finally assembled threeway 14 two ends by the assembly of cloth wall 13 by both direction, and natural pond liquid carries out aerobic and cultivates in discharge nozzle 12 is discharged to one-step fermentation pond 17, cultivate the back and discharge or enter again feed-pipe 8, reach a loop cycle this moment by overflow weir 2.
The enforcement of broken shell
In the two stage fermentation pond, compression zero water level line 20 during the biogas pressure rises, this moment zero water level line 20 following natural pond liquid, a part enters broken shell pipe 9, when zero water level line 20 drops to when equal with broken shell pipe 9 outlet, zero water level line natural pond liquid, no longer enter broken shell pipe 9, and this moment, two stage fermentation pond 16 interior biogas residue and biogas liquids were still pressed by biogas pressure, so liquid natural pond, natural pond slag is forced to flow to threeway 14, the natural pond slag, natural pond liquid, by threeway 14, through discharge nozzle 12, the natural pond slag, natural pond liquid is discharged in the one-step fermentation pond 17, and the natural pond slag in the broken shell this moment pipe 9, natural pond liquid is still by compression, when the natural pond slag, when natural pond liquid sank to bidirectional-reflux hole 10, a part was pressed to feed-pipe 8, a part in bidirectional-reflux hole 10 is discharged to two stage fermentation pond 16, anaerobically fermenting again.
Automatically row's sediment is implemented
The utility model, adopt that flow lifting type is semicontinuous to feed intake, not to feed intake in batches, after so material is absorbed by methanobacteria, though also natural subsidence is scum layer, clear water layer, active coating, sediment layer, but sediment also can not get heavy real just being pressed to threeway 14 by the pressure of biogas, in discharge nozzle 12 is discharged to one-step fermentation pond 17, carry out aerobic and cultivate.
The enforcement of cloth wall
Cloth wall 13 is fan-shaped in two stage fermentation pond 16, account for pond inner area 40%, effectively the width of cloth is penetrated area 85%, and therefore, medium-sized fermentation vat is at 1-5 group feed-pipe 8, under the effect of 1-2 discharge nozzle 12, rate of permeation is more than 95%, and therefore basic non-blind area can mix the bacterium material uniformly, fully enlarge active coating, reduced the sediment layer, the clear water layer, in time removed scum layer, thereby improved factor of created gase.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
