Embodiment
Below in conjunction with accompanying drawing the utility model slot type methane-generating pit is further described:
Side in rectangular methane-generating pit main body 7 is provided with acidifying detritus pool 2 and the charging pond 5 that is connected, acidifying detritus pool 2 one sides are provided with sewage inlet 1, the sewage routeway 3 that opposite side links to each other with charging pond 5 is provided with grid 4, the bottom in charging pond 5 connects feed-pipe 6, feed-pipe 6 stretches into fermentation vat 8 bottoms that are positioned at methane-generating pit main body 7 inside, three row's fixed legs 13 are arranged in the fermentation vat 8, the stirring pipe 14 that is connected is installed on every row's fixed leg, have several on the stirring pipe 14 and be the jet hole that isosceles triangle is arranged, the top of methane-generating pit main body 7 is equipped with removable movable aperture plate 10 and pool cover 11, has the air outlet 12 that joins with user's stove and accessory inlet pipe on the pool cover 11; The opposite side of methane-generating pit main body 7 is provided with deslagging pond 15 and two hydraulic pressure ponds 18 that communicate, the top in hydraulic pressure pond 18 is provided with overflow port 19, the bottom is provided with the overflow pipe 17 that is connected with fermentation vat 8, be provided with automatic sludge discharge pipe 16 between deslagging pond 15 and the fermentation vat 8, automatic sludge discharge pipe 16 is relative with feed-pipe 6 and arranges; The outlet position of feed-pipe 6 in fermentation vat 8 is lower than movable aperture plate 10; Be provided with slope 9 at the bottom of the pond of fermentation vat 8, the inlet of automatic sludge discharge pipe 16 is located at extreme lower position in the pond; The sewage inlet 1 of acidifying detritus pool 2 is higher than the overflow port 19 on 18 tops, hydraulic pressure pond.
The height of described methane-generating pit main body 7 exceeds with the maximum pressure value that produces in the fermentation vat, generally gets 40 centimetres-60 centimetres.
Slope 9 at the bottom of the described pond is put the slope from feed-pipe 6 to automatic sludge discharge pipe 16 directions, can unrestricted flow be advisable with the natural pond slag.
Described overflow pipe 17 is stretched downwards along pool wall after stretching in the fermentation vat, and its degree of depth surpasses 20-50 centimetre of movable aperture plate 10 degree of depth.
The working process of the utility model slot type methane-generating pit is as follows:
The working process of continuously feeding technology is: the animal manure current enter charging pond 5 through grid 4 after acidifying detritus pool 2 sediments are handled, and flow into fermentation vat 8 from feed-pipe 6 again.Other raw material such as stalk then after the chopping stack retting is handled, directly adds from charging pond 5, enters fermentation vat 8 through feed-pipe 6.Liquid manure and other stalk are blended in fermentation generation biogas in the airtight fermentation vat 8, and 12 discharge from the air outlet.
The working process of batch feeding process is: the animal manure current enter charging pond 5 through grid 4 after acidifying detritus pool 2 sediments are handled, and flow into fermentation vats 8 from feed-pipe 6 again; Other raw material such as stalk then after the chopping stack retting is handled, open movable aperture plate 10 and pool cover 11 after, directly from pond body top charging, buckle well movable aperture plate 10 and pool cover 11 then.Liquid manure and other stalk are blended in fermentation generation biogas in the airtight fermentation vat 8, and 12 discharge from the air outlet.
Because raw material fermentation gas in fermentation vat 8, air pressure increases, and the natural pond liquid in the fermentation vat 8 is pressed into hydraulic pressure pond 18 by overflow pipe 17, and the liquid level of fermentation vat 8 descends, and the liquid level in hydraulic pressure pond 18 rises, and when surpassing overflow port 19, natural pond liquid just overflows from overflow port 19; Pond external application gas, the air pressure in the fermentation vat 8 reduces, and under the effect in hydraulic pressure pond 18, the liquid level of fermentation vat 8 gos up, and the natural pond liquid capacity and the air pressure of fermentation vat 8 are remained in the certain limit.Because below liquid level, the crust layer can't generate, and has improved the stalk fermentation effect simultaneously all the time for the buffer action of movable aperture plate 10, scum silica frost and stalk.
Slope 9 at the bottom of the fermentation pond, edge, fresh feed limit is toward the mouth of pipe direction motion of automatic sludge discharge pipe 16, and stalk dissolves the back sedimentation of rotting by fermentation, is piled up in the minimum position of fermentation vat at last, under the internal pressure effect of pond, is discharged to deslagging pond 15 from automatic sludge discharge pipe 16.When needing to stir in the pond, stirring pipe 14 is connected force (forcing) pump, force (forcing) pump is taken out natural pond liquid or external biogas from hydraulic pressure pond 18, and the jet hole on stirring pipe 14 penetrates natural pond liquid or biogas, thereby the natural pond liquid in the agitated pool, anaerobion is fully contacted with fermentation raw material, improve factor of created gase, and destroy and prevent the liquid level crust.
When after operation after a while, throw out increases in the fermentation vat, and stalk fermentation reaches some cycles, in the time of must carrying out big discharging, perhaps during batch charging fermentation discharging, open pool cover 11 and movable aperture plate 10 after, operator just can enter easily and carry out the discharging operation in the pond.
