3, simultaneously can produce 500,000,000 tons of fertilizers, this just for least cost and high benefit process that people live and the waste of production provides best-of-breed technology measure, for resource regeneration and social sustainable development provide technical guarantee.
Existing domestic biogas technology, still the technological phase that rests on lower concentration, poor efficiency, its main drawback is as follows: what 1, traditional methane tank technology adopted is lower concentration zymotechnique, and solid content is low, material concentration is generally only in 6% left and right operation, and production efficiency is low; In structure, have defect, not exclusively, gas producing efficiency is low in digestion.2, present wet type biogas pond is still pass by the original shape of little biogas and is amplified, and charging and the process of slagging tap are poor, and feces of livestock and poultry decomposes thoroughly being difficult to, and makes gas efficiency low, also has insulation difficulty, sand discharge is difficult and the difficult problem such as top junction lid is failed solution.
Utility model content
For above-mentioned deficiency of the prior art, the purpose of this utility model is to provide a kind of insulation, can carry out from stirring, application fee is low and natural pond liquid measure is few and the broad-minded high efficient marsh gas tank in production natural pond, and they can be in the rural households that scale is less relatively.
In order to reach foregoing invention object, the technical solution adopted in the utility model is: a kind of high efficient marsh gas tank that utilizes feces of livestock and poultry is provided, it comprises the high efficient marsh gas tank that utilizes feces of livestock and poultry, comprises biomass pool body, is provided with opening for feed, biogas output tube and ash shoot in described biomass pool body; The middle part of described biomass pool body is provided with the filter mesh layer of a thick slag floating of restriction; The sidewall of described biomass pool body is comprised of inner sealant layer, insulating brick-layer and outer sealing layers, is also provided with one deck impervious barrier on described inner sealant layer; On described biogas output tube, by magnetic valve, be connected with an arm, described arm is connected with biomass pool body, and the distance between the end of arm and the diapire of biomass pool body is arranged in 2cm-5cm.
During design, preferred described opening for feed is connected with the lower end of biomass pool body sidewall.
During design, further on preferred described ash shoot, a sealing cover is installed.
During design, further on preferred described biogas output tube, be provided with moisture eliminator.
During design, more further on preferred described biogas output tube, be also provided with devulcanizer.
Compare with the methane-generating pit of prior art, the beneficial effects of the utility model are:
The feces of livestock and poultry that the filter mesh layer arranging can make to enter by opening for feed is immersed in and in solution, carries out anaerobic reaction, the biogas entering by arm can stir the solution in biomass pool body, make organism fully and microorganism carry out aerobic reaction, guaranteed that this programme has advantages of few compared with the natural pond liquid measure of large biogas production amount and generation; Insulating brick-layer in biomass pool body sidewall can guarantee reaction produces in biomass pool body heat not to external diffusion to improve the fermentation rate of solution in biomass pool body; Arranging of impervious barrier can avoid natural pond liquid to permeate to the external world, causes methane-generating pit environment around to be polluted.
Accompanying drawing explanation
Fig. 1 is the structural representation that utilizes the high efficient marsh gas tank of feces of livestock and poultry.
Wherein, 1, outer sealing layers; 2, insulating brick-layer; 3, opening for feed; 4, inner sealant layer; 5, biogas output tube; 6, arm; 7, magnetic valve; 8, moisture eliminator; 9, devulcanizer; 10, ash shoot; 11, biomass pool body; 12, filter mesh layer.
Embodiment
As shown in Figure 1, this utilizes the high efficient marsh gas tank of feces of livestock and poultry to comprise and utilizes the high efficient marsh gas tank of feces of livestock and poultry to comprise biomass pool body 11, be provided with opening for feed 3, biogas output tube 5 and ash shoot 10 in described biomass pool body 11; The middle part of described biomass pool body 11 is provided with the filter mesh layer 12 of a thick slag floating of restriction; Filter mesh layer 12 can stop that feces of livestock and poultry, thick slag etc. are to floating, it is immersed in fully and in solution, carries out anaerobic reaction.
The sidewall of biomass pool body 11 is comprised of inner sealant layer 4, insulating brick-layer 2 and outer sealing layers 1, insulating brick-layer 2 can guarantee heat that the interior reaction of biomass pool body 11 produces not to external diffusion to improve the fermentation rate of biomass pool body 11 interior solution.On described inner sealant layer 4, be also provided with one deck impervious barrier, it avoids natural pond liquid to permeate to the external world, causes methane-generating pit environment around to be polluted.
