Described anaerobically fermenting mechanism is methane-generating pit, be arranged on raw materials pretreatment mechanism lower end, it adopts domes, be two skene arch compositions up and down, comprise more than 2 and pond of itemizing, each single pond comprises fermentation vat 6, feed-pipe 7, natural pond liquid storage pool 8, liquid discharge pipe 9 and airway 10, airway 10 is communicated with gas storage holder 11 with fermentation vat 6, described gas storage holder 11 is provided with two, each single pond gas storage holder 11 is collected to large gas-holder, the natural pond liquid storage pool 8 in each single pond is pooled to natural pond liquid hold tank, is provided with liquid discharge pipe 9.
Stirrer can be provided with at described Dan Chi top, improve attenuation degree.
Two-stage precipitate and separate groove in the utility model raw materials pretreatment mechanism effectively can improve the sedimentation effect of solid matter in solidliquid mixture, and described density pond provides two solid matter output channels simultaneously, improves the efficiency of subsequent solid mass treatment; This biogas fermentation device is rational in infrastructure, stress performance good, weather resistance is strong; This device adopts many ponds to combine, can effective water distribution and to dam pollution, bears greater impact load, ensure that piggery wastewater is able to efficient process; This device is suited measures to local conditions, laid down cost is low, construction period is short, go into operation then and take effect, good sewage processing effect, rear utilization is reasonable, become large-scale " pig-natural pond-really " development mode of pig farm, biogas engineering and garden spot, economy and environment benefit is very remarkable, and results form investment level is high, achieves the lower cost under equal index.
Accompanying drawing explanation
Fig. 1 is the structural representation of described plant biogas fermentation device;
Fig. 2 is described two-stage precipitate and separate groove structural representation;
Fig. 3 is the internal structure schematic diagram in described single pond;
In figure, density pond 3, flash trapping stage device No. 2, two, 1, density pond, discharge pipe 4, square breach 5, fermentation vat 6, feed-pipe 7, natural pond liquid storage pool 8, liquid discharge pipe 9, airway 10, gas storage holder 11.
Embodiment
Below in conjunction with accompanying drawing and explanation, the present invention is further described.
embodiment 1
As shown in Figure 1, 2, 3, a kind of plant biogas fermentation device described in the present embodiment, comprises raw materials pretreatment mechanism and anaerobically fermenting mechanism; Described raw materials pretreatment mechanism is solid-liquid separator, comprise flash trapping stage device 1 and secondary separation device, wherein flash trapping stage device 1 is woven plastics filter screen or bamboo sieve plate, and it is arranged between pig house and fermentation unit, from height to low setting, favourable physical features is utilized to carry out raw material gravity flow; Described secondary separation device is two-stage precipitate and separate groove, the density pond that this precipitate and separate groove is not waited by two volumes is formed by connecting, No. two density pond 3 volumes are 2 to 3 times of density pond 2 volume, pipe material 4 is all set out bottom a density pond 2 and No. two density ponds 3, and be equipped with a square breach 5 above side, to realize the flowing of solidliquid mixture; Arrange breach between a density pond 2 and No. two density ponds 3 to enter No. two density ponds 3 by the post-depositional solidliquid mixture of one-level and carry out secondary deposition; Liquid after secondary deposition is discharged by No. two density pond 3 opposite side setting party v notch vs 5; Described anaerobically fermenting mechanism is methane-generating pit, be arranged on raw materials pretreatment mechanism lower end, it adopts domes, be two skene arch compositions up and down, comprise more than 2 and pond of itemizing, each single pond comprises fermentation vat 6, feed-pipe 7, natural pond liquid storage pool 8, liquid discharge pipe 9 and airway 10, airway 10 is communicated with gas storage holder 11 with fermentation vat 6, described gas storage holder 11 is provided with two, each single pond gas storage holder 11 is collected to large gas-holder, the natural pond liquid storage pool 8 in each single pond is pooled to natural pond liquid hold tank, is provided with liquid discharge pipe 9.
During the work of this device, carry out according to following flow process: first the solidliquid mixture after flash trapping stage device 1 is separated enters a less density pond 2 of volume, because the density of solid matter is higher than the density of liquid, solid matter will deposit in a density pond 2 greatly.Meanwhile, because the volume restriction in hydraulic shock and density pond makes a part of solid matter can not deposit in a density pond 2, the liquid in a density pond 2 can be suspended at the middle and upper levels.And automatically can enter No. two density ponds 3 by the square breach 5 in side, a density pond 2 after the solid matter on upper strata to certain altitude, the mixture recovery be actually a density pond 2 processed deposits again.The volume that No. two density ponds 3 are larger and less mobility make solid matter obtain enough depositing times and space, the solid matter do not deposited in a density pond 2 is fully deposited, improves the quality of biogas fermentation material.
